today's mission actually began back on

88
00:18:32,470 --> 00:18:29,520
saturday may 30th when falcon 9 launched

89
00:18:34,789 --> 00:18:32,480
dragon from historic launch pad 39a at

90
00:18:36,789 --> 00:18:34,799
kennedy space center in florida

91
00:18:38,390 --> 00:18:36,799
following that successful liftoff bob

92
00:18:40,630 --> 00:18:38,400
and doug arrived at the space station

93
00:18:43,190 --> 00:18:40,640
just 19 hours later and have been there

94
00:18:45,750 --> 00:18:43,200
ever since while on board station for

95
00:18:48,070 --> 00:18:45,760
the last two months bob and doug have

96
00:18:50,230 --> 00:18:48,080
done over 100 hours of work on

97
00:18:52,390 --> 00:18:50,240
microgravity science experiments and

98
00:18:54,390 --> 00:18:52,400
performed four space walks with fellow

99
00:18:57,190 --> 00:18:54,400
nasa astronaut and station commander

100
00:18:59,270 --> 00:18:57,200
chris cassidy dragon's return to earth

101
00:19:01,270 --> 00:18:59,280
will mark the completion of spacex's

102
00:19:03,350 --> 00:19:01,280
second demonstration mission for nasa's

103
00:19:05,270 --> 00:19:03,360
commercial crew program this is an

104
00:19:07,190 --> 00:19:05,280
important and final milestone which will

105
00:19:09,430 --> 00:19:07,200
allow spacex to start flying official

106
00:19:11,350 --> 00:19:09,440
crude missions starting later this year

107
00:19:13,750 --> 00:19:11,360
and it's been a really

108
00:19:15,669 --> 00:19:13,760
eventful 24 hours

109
00:19:17,510 --> 00:19:15,679
for the dragon crew for the

110
00:19:18,950 --> 00:19:17,520
international space station just for

111
00:19:19,830 --> 00:19:18,960
everybody that's been following this

112
00:19:22,150 --> 00:19:19,840
mission

113
00:19:25,110 --> 00:19:22,160
as we literally just heard bob and doug

114
00:19:26,870 --> 00:19:25,120
now awake inside crew dragon endeavour

115
00:19:27,750 --> 00:19:26,880
getting a special message from their

116
00:19:29,830 --> 00:19:27,760
sons

117
00:19:32,310 --> 00:19:29,840
to wake them up on their return day so

118
00:19:33,909 --> 00:19:32,320
that was just really special

119
00:19:35,590 --> 00:19:33,919
they've been flying free from the

120
00:19:38,310 --> 00:19:35,600
international space station for almost

121
00:19:40,630 --> 00:19:38,320
12 hours now since they departed

122
00:19:42,549 --> 00:19:40,640
yesterday they were able to get on board

123
00:19:45,350 --> 00:19:42,559
pack everything up and autonomously

124
00:19:48,710 --> 00:19:45,360
undock from the space station at 4 35 pm

125
00:19:50,870 --> 00:19:48,720
pacific time on saturday and after that

126
00:19:53,029 --> 00:19:50,880
dragon was on its way began a series of

127
00:19:55,110 --> 00:19:53,039
departure burns to move it slowly up and

128
00:19:56,789 --> 00:19:55,120
around the station eventually down below

129
00:19:58,470 --> 00:19:56,799
and out in front getting out of the

130
00:20:00,789 --> 00:19:58,480
neighborhood bringing us out of those

131
00:20:03,110 --> 00:20:00,799
joint operations and setting it up for

132
00:20:04,789 --> 00:20:03,120
its eventual journey home we're going to

133
00:20:06,470 --> 00:20:04,799
be bringing you our live coverage we've

134
00:20:08,149 --> 00:20:06,480
been going ever since

135
00:20:10,070 --> 00:20:08,159
before they got into dragon and we're

136
00:20:11,669 --> 00:20:10,080
going to continue all the way through to

137
00:20:13,430 --> 00:20:11,679
splash down some of the major stuff

138
00:20:15,830 --> 00:20:13,440
coming up will be when we jettison

139
00:20:17,750 --> 00:20:15,840
dragon's trunk we execute the deorbit

140
00:20:20,230 --> 00:20:17,760
burn and then we hit that splashdown

141
00:20:22,630 --> 00:20:20,240
which right now is targeted for 11 48

142
00:20:24,310 --> 00:20:22,640
a.m pacific as kate just said off the

143
00:20:26,950 --> 00:20:24,320
coast of florida we're looking off the

144
00:20:28,470 --> 00:20:26,960
coast of pensacola uh one thing to note

145
00:20:31,110 --> 00:20:28,480
we're not going to be able to show you

146
00:20:32,870 --> 00:20:31,120
every step of dragon's journey as we're

147
00:20:35,270 --> 00:20:32,880
going to have sporadic views inside the

148
00:20:37,350 --> 00:20:35,280
cabin once bob and doug let us want back

149
00:20:38,870 --> 00:20:37,360
on board once they're done with their

150
00:20:40,230 --> 00:20:38,880
post sleep period

151
00:20:42,070 --> 00:20:40,240
and there will be a communications

152
00:20:44,310 --> 00:20:42,080
blackout that we'll have during the

153
00:20:46,549 --> 00:20:44,320
final phases of re-entry and that'll

154
00:20:48,549 --> 00:20:46,559
last for about six minutes but dragon

155
00:20:50,789 --> 00:20:48,559
continues flying itself it's a planned

156
00:20:52,870 --> 00:20:50,799
blackout and we'll see them on the other

157
00:20:55,430 --> 00:20:52,880
side yeah so as you just heard bob and

158
00:20:57,110 --> 00:20:55,440
doug are now awake and entering their

159
00:20:58,390 --> 00:20:57,120
post-sleep period so that's about an

160
00:21:00,630 --> 00:20:58,400
hour-long

161
00:21:02,870 --> 00:21:00,640
period where they're able to get up

162
00:21:04,870 --> 00:21:02,880
stretch their legs have their breakfast

163
00:21:06,470 --> 00:21:04,880
and get ready for splashdown day really

164
00:21:09,270 --> 00:21:06,480
exciting day it's it's going to be a

165
00:21:11,350 --> 00:21:09,280
really busy day for them

166
00:21:13,669 --> 00:21:11,360
more so on the on the second side of

167
00:21:15,750 --> 00:21:13,679
this they had to

168
00:21:18,950 --> 00:21:15,760
it's a 19 hour journey essentially from

169
00:21:21,270 --> 00:21:18,960
space station to that splashdown and

170
00:21:23,350 --> 00:21:21,280
we do that very specifically whenever a

171
00:21:25,590 --> 00:21:23,360
journey from the space station to

172
00:21:27,830 --> 00:21:25,600
the actual splashdown is longer than six

173
00:21:29,350 --> 00:21:27,840
hours we have to build in sleep for our

174
00:21:32,390 --> 00:21:29,360
crew members otherwise they end up

175
00:21:33,909 --> 00:21:32,400
pulling about 20 plus hour days and we

176
00:21:36,070 --> 00:21:33,919
don't want them going through something

177
00:21:38,310 --> 00:21:36,080
as dynamic as that reentry that splashed

178
00:21:40,230 --> 00:21:38,320
down in the ocean got to get rested yeah

179
00:21:41,830 --> 00:21:40,240
got to make sure it's it's almost it's

180
00:21:43,590 --> 00:21:41,840
like pilots it's like anybody else you

181
00:21:45,750 --> 00:21:43,600
have kind of that very strict crew duty

182
00:21:48,390 --> 00:21:45,760
day so they are awake now though they've

183
00:21:49,750 --> 00:21:48,400
got some post-sleep time and

184
00:21:51,430 --> 00:21:49,760
after that

185
00:21:52,950 --> 00:21:51,440
they'll be ready to monitor dragon the

186
00:21:54,310 --> 00:21:52,960
whole way down because it is going to be

187
00:21:56,310 --> 00:21:54,320
pretty much all automated yeah

188
00:21:58,390 --> 00:21:56,320
absolutely they'll have everything

189
00:22:00,950 --> 00:21:58,400
available for them on their screens as

190
00:22:02,630 --> 00:22:00,960
they monitor telemetry and attitude and

191
00:22:04,630 --> 00:22:02,640
all that good stuff

192
00:22:07,029 --> 00:22:04,640
so yeah really exciting day as we

193
00:22:09,830 --> 00:22:07,039
approach our uh as we approach

194
00:22:12,070 --> 00:22:09,840
splashdown here in a matter of a few

195
00:22:13,669 --> 00:22:12,080
hours which is crazy to think that this

196
00:22:14,789 --> 00:22:13,679
all started two months ago and here we

197
00:22:17,909 --> 00:22:14,799
are

198
00:22:19,990 --> 00:22:17,919
time certainly flew by so uh while bob

199
00:22:22,070 --> 00:22:20,000
and doug are now in their post-sleep

200
00:22:23,990 --> 00:22:22,080
period let's check in with the team in

201
00:22:28,870 --> 00:22:24,000
mission control houston and nasa's

202
00:22:33,029 --> 00:22:30,789
thanks kate i cannot imagine a better

203
00:22:34,950 --> 00:22:33,039
wake-up call for our two space dads as

204
00:22:36,870 --> 00:22:34,960
you can tell we've changed locations

205
00:22:39,190 --> 00:22:36,880
since our teams were on for undocking

206
00:22:40,870 --> 00:22:39,200
and departure as part of the coronavirus

207
00:22:42,470 --> 00:22:40,880
protections we have in place to protect

208
00:22:44,149 --> 00:22:42,480
our flight controllers performing

209
00:22:45,510 --> 00:22:44,159
critical operations here in mission

210
00:22:47,590 --> 00:22:45,520
control houston

211
00:22:49,270 --> 00:22:47,600
since dragon's departure it's been back

212
00:22:50,710 --> 00:22:49,280
to business as usual for our

213
00:22:53,029 --> 00:22:50,720
international space station flight

214
00:22:55,990 --> 00:22:53,039
controllers we transitioned out of the

215
00:22:57,590 --> 00:22:56,000
joint operations after dragon departed

216
00:22:59,909 --> 00:22:57,600
the approach ellipsoid but have

217
00:23:02,630 --> 00:22:59,919
continued to monitor bob and doug's

218
00:23:04,870 --> 00:23:02,640
flight home the team here in houston is

219
00:23:07,430 --> 00:23:04,880
still playing a few roles with dragon's

220
00:23:09,430 --> 00:23:07,440
return trip and recovery are toppo or

221
00:23:10,470 --> 00:23:09,440
trajectory operations and planning

222
00:23:12,710 --> 00:23:10,480
officer

223
00:23:14,870 --> 00:23:12,720
is continuing to monitor dragon's path

224
00:23:16,710 --> 00:23:14,880
on the lookout for any conjunctions or

225
00:23:19,350 --> 00:23:16,720
chances of any space debris that could

226
00:23:21,270 --> 00:23:19,360
get in the way of dragon's return we

227
00:23:23,669 --> 00:23:21,280
also have a representative from nasa's

228
00:23:25,990 --> 00:23:23,679
flight operations directorate on console

229
00:23:27,750 --> 00:23:26,000
to serve as an information clearinghouse

230
00:23:30,230 --> 00:23:27,760
for all nasa personnel supporting

231
00:23:33,110 --> 00:23:30,240
splashdown and providing input should

232
00:23:34,630 --> 00:23:33,120
any changes to return need to take place

233
00:23:36,710 --> 00:23:34,640
there's also our space flight

234
00:23:39,270 --> 00:23:36,720
meteorology group actively providing

235
00:23:41,830 --> 00:23:39,280
weather updates to our two nasa and

236
00:23:43,990 --> 00:23:41,840
spacex teams together making sure that

237
00:23:47,190 --> 00:23:44,000
the weather in the gulf is clear for

238
00:23:49,990 --> 00:23:47,200
landing later today and finally our lso

239
00:23:51,590 --> 00:23:50,000
orlando support officer is on standby in

240
00:23:53,990 --> 00:23:51,600
the event that we would run into any

241
00:23:55,750 --> 00:23:54,000
major issues that would cause dragon to

242
00:23:57,909 --> 00:23:55,760
end up in an unsupported splashdown

243
00:23:59,750 --> 00:23:57,919
location where we'd then call upon

244
00:24:01,990 --> 00:23:59,760
support from our department of defense

245
00:24:03,510 --> 00:24:02,000
colleagues we'll continue to monitor all

246
00:24:05,909 --> 00:24:03,520
the way through splashdown today from

247
00:24:09,269 --> 00:24:05,919
mission control houston until then back

248
00:24:11,350 --> 00:24:09,279
to you dan and kate in hawthorne

249
00:24:12,470 --> 00:24:11,360
all right thank you so much courtney so

250
00:24:14,470 --> 00:24:12,480
we're going to walk you through some of

251
00:24:16,710 --> 00:24:14,480
the dynamic activities that are coming

252
00:24:18,870 --> 00:24:16,720
up now that the crew is awake as we said

253
00:24:20,710 --> 00:24:18,880
it's going to be a couple of hours uh

254
00:24:22,710 --> 00:24:20,720
roughly six hours from now so we still

255
00:24:24,390 --> 00:24:22,720
got a little bit of a ways to go

256
00:24:26,390 --> 00:24:24,400
but once we start getting ready for

257
00:24:28,070 --> 00:24:26,400
dragon to come home there's a very

258
00:24:30,230 --> 00:24:28,080
specific set of milestones that will

259
00:24:32,310 --> 00:24:30,240
take place one of the first ones that'll

260
00:24:34,070 --> 00:24:32,320
happen is we'll do a slew maneuver which

261
00:24:36,070 --> 00:24:34,080
is essentially changing dragon's

262
00:24:38,390 --> 00:24:36,080
attitude to get it ready to jettison the

263
00:24:39,990 --> 00:24:38,400
trunk uh the trunk of the spacecraft if

264
00:24:41,430 --> 00:24:40,000
you can think of dragon it's kind of two

265
00:24:43,029 --> 00:24:41,440
different parts you have the top part

266
00:24:44,470 --> 00:24:43,039
which is the capsule where the crew is

267
00:24:47,590 --> 00:24:44,480
and the cargo and then you have the

268
00:24:49,350 --> 00:24:47,600
trunk which has uh the solar array that

269
00:24:51,190 --> 00:24:49,360
has been generating all the electricity

270
00:24:53,110 --> 00:24:51,200
for dragon throughout its flight

271
00:24:55,190 --> 00:24:53,120
and also the radiator which is used to

272
00:24:56,950 --> 00:24:55,200
reject heat created by all dragon

273
00:24:58,950 --> 00:24:56,960
systems and we get rid of that trunk

274
00:25:00,870 --> 00:24:58,960
before we re-enter it burns up in the

275
00:25:02,870 --> 00:25:00,880
atmosphere and that reveals the heat

276
00:25:05,750 --> 00:25:02,880
shield of the capsule itself so we'll

277
00:25:07,750 --> 00:25:05,760
first do a maneuver at about 10 48 a.m

278
00:25:10,310 --> 00:25:07,760
pacific just to get ready for that

279
00:25:11,750 --> 00:25:10,320
jettison then the claw mechanism will

280
00:25:13,909 --> 00:25:11,760
separate that's what actually connects

281
00:25:15,909 --> 00:25:13,919
the trunk to the dragon spacecraft

282
00:25:17,750 --> 00:25:15,919
followed just seconds later by that

283
00:25:19,669 --> 00:25:17,760
trunk separation

284
00:25:22,230 --> 00:25:19,679
yeah then after we jettison that trunk

285
00:25:24,630 --> 00:25:22,240
away we will then maneuver or slew to

286
00:25:26,310 --> 00:25:24,640
deorbit burn attitude and that is

287
00:25:29,350 --> 00:25:26,320
essentially putting the vehicle in the

288
00:25:32,149 --> 00:25:29,360
proper position for that deorbit burn uh

289
00:25:36,070 --> 00:25:32,159
the deorbit burn will commence at 10 50

290
00:25:38,070 --> 00:25:36,080
10 10 and 10 56 a.m pacific time and

291
00:25:41,110 --> 00:25:38,080
it'll last for about 11 and a half

292
00:25:44,070 --> 00:25:41,120
minutes that deorbit burn is essentially

293
00:25:46,390 --> 00:25:44,080
placing dragon endeavor on its final

294
00:25:48,310 --> 00:25:46,400
trajectory to the landing uh landing

295
00:25:49,750 --> 00:25:48,320
point off the coast of florida near

296
00:25:52,310 --> 00:25:49,760
pensacola

297
00:25:55,590 --> 00:25:52,320
after that deorbit burn is completed at

298
00:25:57,750 --> 00:25:55,600
11 11 a.m we will be closing that nose

299
00:25:59,590 --> 00:25:57,760
cone again we want to reuse these

300
00:26:01,430 --> 00:25:59,600
capsules and protecting that forward

301
00:26:04,149 --> 00:26:01,440
hatch at the top of the capsule is

302
00:26:05,909 --> 00:26:04,159
essential as that is where the dragon

303
00:26:07,990 --> 00:26:05,919
capsule endeavor or where the dragon

304
00:26:09,350 --> 00:26:08,000
capsule crew capsule

305
00:26:11,350 --> 00:26:09,360
connects to the international space

306
00:26:13,909 --> 00:26:11,360
station and that's what the crew uses to

307
00:26:15,750 --> 00:26:13,919
ingress an egress from the capsule so we

308
00:26:18,549 --> 00:26:15,760
will close that nose cone to protect the

309
00:26:20,950 --> 00:26:18,559
hatch for re-entry uh around then just a

310
00:26:22,630 --> 00:26:20,960
couple minutes after that uh the dragon

311
00:26:25,190 --> 00:26:22,640
capsule will begin to re-enter the

312
00:26:26,789 --> 00:26:25,200
earth's atmosphere so a lot of plasma

313
00:26:27,990 --> 00:26:26,799
will be building up on the exterior of

314
00:26:30,310 --> 00:26:28,000
the capsule

315
00:26:32,789 --> 00:26:30,320
and as such we won't be able to command

316
00:26:34,950 --> 00:26:32,799
the vehicle from here but it is steering

317
00:26:37,669 --> 00:26:34,960
itself it is completely autonomous but

318
00:26:39,350 --> 00:26:37,679
we will be experiencing an unexpected

319
00:26:42,789 --> 00:26:39,360
communications blackout and that will

320
00:26:45,350 --> 00:26:42,799
begin at 11 36 a.m and it'll last for

321
00:26:47,190 --> 00:26:45,360
about six minutes so uh while that's

322
00:26:48,710 --> 00:26:47,200
happening we will have what's called

323
00:26:50,710 --> 00:26:48,720
entry interface

324
00:26:53,269 --> 00:26:50,720
that is whenever the vehicle will begin

325
00:26:56,789 --> 00:26:53,279
to experience the aerodynamic pressures

326
00:26:59,990 --> 00:26:56,799
and loads of earth's atmosphere so uh

327
00:27:01,990 --> 00:27:00,000
that's what the really exciting point

328
00:27:05,430 --> 00:27:02,000
and then we will get our communications

329
00:27:08,070 --> 00:27:05,440
back at 11 42 a.m so all that kind of

330
00:27:09,909 --> 00:27:08,080
leading up to the big visual fun part

331
00:27:13,190 --> 00:27:09,919
the parachutes

332
00:27:14,950 --> 00:27:13,200
come out in two different stages we'll

333
00:27:17,190 --> 00:27:14,960
start off with the drogue parachutes

334
00:27:19,029 --> 00:27:17,200
those will do the initial slowing now

335
00:27:20,310 --> 00:27:19,039
you have to imagine when dragon starts

336
00:27:23,190 --> 00:27:20,320
hitting the earth's atmosphere it's

337
00:27:25,269 --> 00:27:23,200
moving about 17 500 miles an hour that's

338
00:27:27,350 --> 00:27:25,279
its orbital velocity as it's flying

339
00:27:29,190 --> 00:27:27,360
around planet earth by the time the

340
00:27:31,190 --> 00:27:29,200
drogue shoots come out just after that

341
00:27:33,669 --> 00:27:31,200
de-orbit burn and that re-entry it's

342
00:27:35,909 --> 00:27:33,679
already slowed down to about 350 miles

343
00:27:38,470 --> 00:27:35,919
an hour two drove shoots will come out

344
00:27:40,070 --> 00:27:38,480
and do the uh some initial slowing of

345
00:27:41,990 --> 00:27:40,080
the vehicle and also stabilize the

346
00:27:43,669 --> 00:27:42,000
capsule as it continues to descend

347
00:27:45,750 --> 00:27:43,679
through the thicker part of earth's

348
00:27:48,789 --> 00:27:45,760
atmosphere those drugs should come out

349
00:27:52,070 --> 00:27:48,799
right around 11 44 a.m pacific while the

350
00:27:54,389 --> 00:27:52,080
capsule is about 18 000 feet in altitude

351
00:27:57,269 --> 00:27:54,399
uh just less than a minute after those

352
00:27:59,110 --> 00:27:57,279
droves are done with their job they will

353
00:28:01,750 --> 00:27:59,120
jettison and they'll actually draw out

354
00:28:03,350 --> 00:28:01,760
four main parachutes which will do the

355
00:28:06,710 --> 00:28:03,360
final slowing of the vehicle those will

356
00:28:09,029 --> 00:28:06,720
pop out at about 6 500 feet in altitude

357
00:28:10,950 --> 00:28:09,039
and when the spacecraft's moving only

358
00:28:12,950 --> 00:28:10,960
119 miles an hour so we've already

359
00:28:14,710 --> 00:28:12,960
slowed down quite a bit by that point

360
00:28:17,190 --> 00:28:14,720
those main parachutes will do the final

361
00:28:19,590 --> 00:28:17,200
slowing down before we do the splashdown

362
00:28:21,750 --> 00:28:19,600
it'll be moving at about 15 or 16 miles

363
00:28:23,909 --> 00:28:21,760
an hour once it hits the water and at

364
00:28:27,510 --> 00:28:23,919
that point we are looking at it at about

365
00:28:31,029 --> 00:28:27,520
11 48 a.m pacific for their splashdown

366
00:28:34,149 --> 00:28:31,039
in the gulf off of the coast of florida

367
00:28:35,830 --> 00:28:34,159
yeah and of course uh the recovery team

368
00:28:37,190 --> 00:28:35,840
will be there ready and waiting for bob

369
00:28:39,510 --> 00:28:37,200
and doug

370
00:28:41,909 --> 00:28:39,520
in preparation for this splashdown uh

371
00:28:44,230 --> 00:28:41,919
the the recovery team has been busy over

372
00:28:46,549 --> 00:28:44,240
the last week one of their big ticket

373
00:28:49,269 --> 00:28:46,559
items has been the final selection of

374
00:28:51,350 --> 00:28:49,279
the landing site to increase the options

375
00:28:53,430 --> 00:28:51,360
for space station departure the teams

376
00:28:55,269 --> 00:28:53,440
identified a total of seven possible

377
00:28:57,669 --> 00:28:55,279
splashdown locations

378
00:28:58,950 --> 00:28:57,679
also in order to meet nasa's timeline

379
00:29:05,669 --> 00:28:58,960
for

380
00:29:08,070 --> 00:29:05,679
the the potential splashdown locations

381
00:29:10,549 --> 00:29:08,080
have to be close to a port as well as

382
00:29:12,389 --> 00:29:10,559
medical facilities so with all of that

383
00:29:13,990 --> 00:29:12,399
in mind add the evolving weather

384
00:29:16,870 --> 00:29:14,000
conditions from

385
00:29:19,350 --> 00:29:16,880
tropical storm isaiah and it's easy to

386
00:29:21,190 --> 00:29:19,360
see how determining the landing site is

387
00:29:23,830 --> 00:29:21,200
a complex process

388
00:29:25,990 --> 00:29:23,840
since dragon is capable of splashdown on

389
00:29:27,990 --> 00:29:26,000
either side of the florida panhandle we

390
00:29:29,750 --> 00:29:28,000
actually have two identical and fully

391
00:29:32,230 --> 00:29:29,760
equipped recovery vessels ready and

392
00:29:33,990 --> 00:29:32,240
waiting to support so one is in the gulf

393
00:29:35,190 --> 00:29:34,000
of mexico and the other in the atlantic

394
00:29:36,870 --> 00:29:35,200
ocean which

395
00:29:39,510 --> 00:29:36,880
of course will stay there

396
00:29:41,990 --> 00:29:39,520
so the go navigator is the vessel that

397
00:29:44,950 --> 00:29:42,000
we have in the gulf of mexico and like i

398
00:29:47,830 --> 00:29:44,960
said today we'll be splashing down just

399
00:29:49,510 --> 00:29:47,840
off the coast of pensacola florida

400
00:29:51,830 --> 00:29:49,520
now in addition to weather which has

401
00:29:53,510 --> 00:29:51,840
really been the key thing we've been

402
00:29:55,110 --> 00:29:53,520
watching over the last it's kind of been

403
00:29:56,870 --> 00:29:55,120
a theme to this mission as we were

404
00:29:58,630 --> 00:29:56,880
watching weather so closely for their

405
00:30:01,029 --> 00:29:58,640
launch and we've been watching it very

406
00:30:02,789 --> 00:30:01,039
closely for this return the crew sleep

407
00:30:05,590 --> 00:30:02,799
schedule is actually a really important

408
00:30:06,950 --> 00:30:05,600
factor in how we decide how long it's

409
00:30:08,630 --> 00:30:06,960
going to take for them to come home and

410
00:30:10,950 --> 00:30:08,640
which landing opportunities we're going

411
00:30:12,950 --> 00:30:10,960
to take i mean every single day dragon

412
00:30:15,269 --> 00:30:12,960
has multiple landing opportunities that

413
00:30:16,789 --> 00:30:15,279
are identified by the spacex team and

414
00:30:18,870 --> 00:30:16,799
then those will range anywhere from

415
00:30:20,950 --> 00:30:18,880
about six hours from station to a

416
00:30:22,950 --> 00:30:20,960
splashdown all the way up to in excess

417
00:30:25,110 --> 00:30:22,960
of 30 hours from an undoctor's flash

418
00:30:27,430 --> 00:30:25,120
down so we try to target the ones that

419
00:30:29,510 --> 00:30:27,440
are in that sweet spot where we're not

420
00:30:30,950 --> 00:30:29,520
going 30 hours from them leaving to

421
00:30:33,029 --> 00:30:30,960
getting back home

422
00:30:34,630 --> 00:30:33,039
but we're also going at an appropriate

423
00:30:36,789 --> 00:30:34,640
amount of time where they're going to be

424
00:30:38,310 --> 00:30:36,799
out of a sleep schedule in between to

425
00:30:39,110 --> 00:30:38,320
make sure they're rested up and ready to

426
00:30:41,590 --> 00:30:39,120
go

427
00:30:43,990 --> 00:30:41,600
for the actual splashdown itself and all

428
00:30:46,389 --> 00:30:44,000
of those recovery operations

429
00:30:48,710 --> 00:30:46,399
dragon's going to change quite a bit

430
00:30:51,350 --> 00:30:48,720
over the course of this reentry as we

431
00:30:53,190 --> 00:30:51,360
said it's made up of both the capsule

432
00:30:55,590 --> 00:30:53,200
and the trunk right now

433
00:30:57,190 --> 00:30:55,600
it weighs in at a little over 27 000

434
00:30:59,909 --> 00:30:57,200
pounds and that trunk is jettisoned it

435
00:31:03,029 --> 00:30:59,919
will go all the way about 21 000 pounds

436
00:31:04,549 --> 00:31:03,039
and again during the heat of reentry is

437
00:31:05,830 --> 00:31:04,559
going to build up on the capsule it's

438
00:31:07,750 --> 00:31:05,840
going to build up a plasma that will

439
00:31:09,509 --> 00:31:07,760
give us that communications blackout

440
00:31:12,389 --> 00:31:09,519
it's also going to heat up the capsule

441
00:31:14,789 --> 00:31:12,399
to about 3 500 degrees fahrenheit during

442
00:31:16,230 --> 00:31:14,799
that re-entry yeah which interestingly

443
00:31:18,549 --> 00:31:16,240
enough uh

444
00:31:20,230 --> 00:31:18,559
the interior of the cabin uh will

445
00:31:22,310 --> 00:31:20,240
actually remain quite comfortable there

446
00:31:23,909 --> 00:31:22,320
are a number of systems in place to make

447
00:31:25,750 --> 00:31:23,919
sure that bob and doug won't be heating

448
00:31:28,310 --> 00:31:25,760
up along with the exterior of the

449
00:31:30,149 --> 00:31:28,320
capsule uh they're expected to i think

450
00:31:31,669 --> 00:31:30,159
the internal capsule temperature is

451
00:31:33,509 --> 00:31:31,679
supposed to stay around 85 degrees

452
00:31:35,830 --> 00:31:33,519
fahrenheit maximum

453
00:31:37,669 --> 00:31:35,840
but there will be cold air flushing

454
00:31:39,830 --> 00:31:37,679
throughout the cabin and throughout bob

455
00:31:40,870 --> 00:31:39,840
and doug suits throughout the reentry

456
00:31:42,710 --> 00:31:40,880
phase so

457
00:31:45,909 --> 00:31:42,720
they really won't be breaking too much

458
00:31:47,990 --> 00:31:45,919
of a sweat during that re-entry period

459
00:31:50,470 --> 00:31:48,000
also something to note

460
00:31:52,710 --> 00:31:50,480
the exterior of the capsule as you may

461
00:31:53,909 --> 00:31:52,720
if you followed along with our demo one

462
00:31:56,470 --> 00:31:53,919
recovery

463
00:31:57,350 --> 00:31:56,480
will due to those extreme temperatures

464
00:32:01,509 --> 00:31:57,360
the

465
00:32:03,669 --> 00:32:01,519
hours of seeing dragon in its pristine

466
00:32:06,149 --> 00:32:03,679
white condition after that re-entry it

467
00:32:08,389 --> 00:32:06,159
will come back with a lot of that

468
00:32:10,870 --> 00:32:08,399
space dust essentially we'll see a lot

469
00:32:12,710 --> 00:32:10,880
of the charring on the external sides of

470
00:32:14,870 --> 00:32:12,720
the of the capsule to the thermal

471
00:32:17,350 --> 00:32:14,880
protective systems that are basically

472
00:32:19,509 --> 00:32:17,360
built to insulate the dragon capsule and

473
00:32:21,830 --> 00:32:19,519
make sure that everything stays safe

474
00:32:23,669 --> 00:32:21,840
during that very heated re-entry period

475
00:32:25,110 --> 00:32:23,679
yeah it's going to be very dynamic for

476
00:32:27,350 --> 00:32:25,120
them it's going to be a new experience i

477
00:32:28,870 --> 00:32:27,360
mean they're experienced astronauts but

478
00:32:30,149 --> 00:32:28,880
this is their first time coming home in

479
00:32:32,070 --> 00:32:30,159
a capsule

480
00:32:34,070 --> 00:32:32,080
both had previously flown on space

481
00:32:35,990 --> 00:32:34,080
shuttle missions so they were used to

482
00:32:37,750 --> 00:32:36,000
kind of the glide down of the space

483
00:32:39,190 --> 00:32:37,760
shuttle onto a runway this is going to

484
00:32:40,470 --> 00:32:39,200
be their first time landing in the

485
00:32:42,389 --> 00:32:40,480
capsule and this is going to be the

486
00:32:45,110 --> 00:32:42,399
first time we've splashed down a capsule

487
00:32:47,509 --> 00:32:45,120
with american astronauts in over 45

488
00:32:48,870 --> 00:32:47,519
years uh the final apollo mission apollo

489
00:32:53,750 --> 00:32:48,880
soyuz

490
00:32:55,750 --> 00:32:53,760
making that splashdown back in 1975. so

491
00:32:58,149 --> 00:32:55,760
another historical milestone here with

492
00:33:00,389 --> 00:32:58,159
this mission that we're going to be

493
00:33:02,230 --> 00:33:00,399
taking today once they actually splash

494
00:33:04,549 --> 00:33:02,240
down on the water though we have a

495
00:33:07,110 --> 00:33:04,559
combined spacex and nasa team that's

496
00:33:09,669 --> 00:33:07,120
going to be standing by to recover them

497
00:33:11,110 --> 00:33:09,679
there will be a little over 40 people on

498
00:33:13,509 --> 00:33:11,120
go navigator

499
00:33:14,549 --> 00:33:13,519
and it's a mix of spacex personnel who

500
00:33:17,269 --> 00:33:14,559
are there

501
00:33:18,149 --> 00:33:17,279
to safe the capsule get it rigged up to

502
00:33:19,669 --> 00:33:18,159
get

503
00:33:20,549 --> 00:33:19,679
lifted out of the water and out of the

504
00:33:22,389 --> 00:33:20,559
boat

505
00:33:24,470 --> 00:33:22,399
and also some medical personnel along

506
00:33:27,029 --> 00:33:24,480
with the nasa contingent where both bob

507
00:33:29,269 --> 00:33:27,039
and doug's flight surgeons are with the

508
00:33:31,190 --> 00:33:29,279
contingent on the boat there they are

509
00:33:34,549 --> 00:33:31,200
responsible for their medical care

510
00:33:36,070 --> 00:33:34,559
before flight during flight and after

511
00:33:38,070 --> 00:33:36,080
and so they'll be there just to help

512
00:33:39,669 --> 00:33:38,080
them out of the capsule and do their

513
00:33:41,350 --> 00:33:39,679
initial medical check right there on the

514
00:33:43,830 --> 00:33:41,360
boat before they make their way back to

515
00:33:46,149 --> 00:33:43,840
shore yeah so earlier in the week bob

516
00:33:47,990 --> 00:33:46,159
and doug did a couple of interviews from

517
00:33:50,470 --> 00:33:48,000
while they were still on station and one

518
00:33:52,470 --> 00:33:50,480
of the questions asked them was are you

519
00:33:55,269 --> 00:33:52,480
nervous about returning

520
00:33:57,830 --> 00:33:55,279
and they said no we've rehearsed this

521
00:33:59,669 --> 00:33:57,840
with the team many many times both uh

522
00:34:01,909 --> 00:33:59,679
digitally as well as in person with the

523
00:34:05,590 --> 00:34:01,919
recovery team actually practicing the

524
00:34:07,110 --> 00:34:05,600
egress operations from the capsule so

525
00:34:08,230 --> 00:34:07,120
coincidentally they said they're they're

526
00:34:10,389 --> 00:34:08,240
not worried about it they're more

527
00:34:13,030 --> 00:34:10,399
worried about the health of their family

528
00:34:15,990 --> 00:34:13,040
uh in the in the midst of the pandemic

529
00:34:17,909 --> 00:34:16,000
more so than uh the return itself uh

530
00:34:20,790 --> 00:34:17,919
when i think about the return i can't

531
00:34:22,950 --> 00:34:20,800
help but to think of g-forces

532
00:34:25,109 --> 00:34:22,960
the the g-forces that we're expecting

533
00:34:27,750 --> 00:34:25,119
them to experience on the way back down

534
00:34:29,829 --> 00:34:27,760
is around four g's they also got around

535
00:34:31,589 --> 00:34:29,839
four g's on the ascent portion of the

536
00:34:33,349 --> 00:34:31,599
mission so this really shouldn't be

537
00:34:34,710 --> 00:34:33,359
anything that they haven't experienced

538
00:34:37,030 --> 00:34:34,720
previously

539
00:34:38,790 --> 00:34:37,040
that is if you think of roller coasters

540
00:34:41,349 --> 00:34:38,800
that's about what a

541
00:34:43,750 --> 00:34:41,359
i would say higher level roller coaster

542
00:34:47,030 --> 00:34:43,760
would deliver as about four g's i tend

543
00:34:49,190 --> 00:34:47,040
to avoid roller coasters at all costs so

544
00:34:50,869 --> 00:34:49,200
you probably won't find me in a crew

545
00:34:52,950 --> 00:34:50,879
capsule anytime soon

546
00:34:53,990 --> 00:34:52,960
that being said bob and doug like we

547
00:34:55,750 --> 00:34:54,000
said before

548
00:34:57,910 --> 00:34:55,760
have rehearsed this many times with the

549
00:34:59,109 --> 00:34:57,920
recovery team with the mission control

550
00:35:00,790 --> 00:34:59,119
operators

551
00:35:01,910 --> 00:35:00,800
and they're excited to come home and

552
00:35:03,190 --> 00:35:01,920
we're looking forward to having them

553
00:35:04,950 --> 00:35:03,200
back on earth

554
00:35:07,270 --> 00:35:04,960
yeah there's

555
00:35:09,510 --> 00:35:07,280
not a ton for them to do between now and

556
00:35:11,270 --> 00:35:09,520
then uh just a couple of the activities

557
00:35:13,589 --> 00:35:11,280
that bob and doug will be doing inside

558
00:35:15,990 --> 00:35:13,599
of dragon they're obviously going to be

559
00:35:17,349 --> 00:35:16,000
monitoring throughout the deorbit burn

560
00:35:19,430 --> 00:35:17,359
prior to that though they're going to be

561
00:35:21,030 --> 00:35:19,440
getting suited back up

562
00:35:23,349 --> 00:35:21,040
they're wearing those launch and entry

563
00:35:25,270 --> 00:35:23,359
suits for all the dynamic phases

564
00:35:27,190 --> 00:35:25,280
obviously for launch and then they wore

565
00:35:28,470 --> 00:35:27,200
them during all the proximity operations

566
00:35:30,790 --> 00:35:28,480
around the space station they'll be in

567
00:35:32,790 --> 00:35:30,800
the suits once more for the actual

568
00:35:35,109 --> 00:35:32,800
splashdown itself again those those

569
00:35:36,710 --> 00:35:35,119
suits are there as just another line of

570
00:35:38,470 --> 00:35:36,720
protection for the crew members

571
00:35:40,470 --> 00:35:38,480
obviously the capsule keeping them safe

572
00:35:42,310 --> 00:35:40,480
in a very hazardous environment of outer

573
00:35:44,550 --> 00:35:42,320
space or

574
00:35:46,950 --> 00:35:44,560
burning up on re-entry with all of that

575
00:35:48,710 --> 00:35:46,960
heat uh and then the suits are just

576
00:35:50,069 --> 00:35:48,720
another line of defense so they'll have

577
00:35:52,390 --> 00:35:50,079
they'll have those worn they'll be

578
00:35:54,470 --> 00:35:52,400
wearing those during the reentry uh

579
00:35:56,390 --> 00:35:54,480
they'll actually do what's called a suit

580
00:35:59,349 --> 00:35:56,400
flush just before they re-enter where

581
00:36:01,109 --> 00:35:59,359
they just inject some cool down nitrox

582
00:36:03,990 --> 00:36:01,119
into the suits just to help with kind of

583
00:36:05,829 --> 00:36:04,000
that conditioning inside of the capsule

584
00:36:07,670 --> 00:36:05,839
and before they get suited up they'll be

585
00:36:09,670 --> 00:36:07,680
doing what's known as fluid loading

586
00:36:10,630 --> 00:36:09,680
that's very common for returning crew

587
00:36:12,790 --> 00:36:10,640
members

588
00:36:15,190 --> 00:36:12,800
you can end up getting very dehydrated

589
00:36:17,910 --> 00:36:15,200
and the fluid loading can help kind of

590
00:36:20,390 --> 00:36:17,920
minimize uh the unpleasant effects of

591
00:36:22,470 --> 00:36:20,400
re-entering a gravity environment

592
00:36:24,870 --> 00:36:22,480
it's very common for returning crew

593
00:36:27,750 --> 00:36:24,880
members from long duration missions

594
00:36:29,589 --> 00:36:27,760
to have some orthostatic intolerance to

595
00:36:31,829 --> 00:36:29,599
have their vestibular system which is

596
00:36:34,230 --> 00:36:31,839
responsible for just maintaining your

597
00:36:36,310 --> 00:36:34,240
balance your motion uh to just really be

598
00:36:38,150 --> 00:36:36,320
all out of whack it's the same when you

599
00:36:40,230 --> 00:36:38,160
first get on board the space station and

600
00:36:41,910 --> 00:36:40,240
you're in microgravity and your inner

601
00:36:43,349 --> 00:36:41,920
ear is trying to tell you which way is

602
00:36:46,230 --> 00:36:43,359
up which way is down it doesn't really

603
00:36:47,750 --> 00:36:46,240
exist anymore and the human body adapts

604
00:36:49,589 --> 00:36:47,760
to that when you're up there for several

605
00:36:51,349 --> 00:36:49,599
months at a time and so when you get

606
00:36:53,990 --> 00:36:51,359
back down to earth it can be a little

607
00:36:56,790 --> 00:36:54,000
bit jarring but that's why we have a lot

608
00:37:00,310 --> 00:36:56,800
of trained personnel there on site ready

609
00:37:02,150 --> 00:37:00,320
to help them out of the castle

610
00:37:05,750 --> 00:37:02,160
jay if you're ready we are ready for the

611
00:37:09,990 --> 00:37:06,790
coffee

612
00:37:11,190 --> 00:37:10,000
um yeah as stated dragon's in a healthy

613
00:37:13,270 --> 00:37:11,200
state

614
00:37:16,630 --> 00:37:13,280
we are proceeding toward the primary

615
00:37:20,390 --> 00:37:18,950
and your timeline is current

616
00:37:22,790 --> 00:37:20,400
to pensacola

617
00:37:25,270 --> 00:37:22,800
the weather's looking great forecasted

618
00:37:26,470 --> 00:37:25,280
winds are one knot and seas are very

619
00:37:27,670 --> 00:37:26,480
calm

620
00:37:29,589 --> 00:37:27,680
we are working an issue with the

621
00:37:32,230 --> 00:37:29,599
generator on the recovery ship that has

622
00:37:34,950 --> 00:37:32,240
eliminated power redundancy but we're

623
00:37:36,630 --> 00:37:34,960
working a plan to get a backup generator

624
00:37:38,870 --> 00:37:36,640
even without this resolved we do expect

625
00:37:41,030 --> 00:37:38,880
the ship to be at the designated

626
00:37:43,589 --> 00:37:41,040
landing site and no impact to your

627
00:37:49,990 --> 00:37:43,599
egress timeline and that is all we have

628
00:37:55,589 --> 00:37:52,470
okay we copy all that's uh news about

629
00:37:57,349 --> 00:37:55,599
the weather and uh i'm sure the folks on

630
00:37:59,510 --> 00:37:57,359
the ship will get something sorted out

631
00:38:06,230 --> 00:37:59,520
uh with that generator thanks for the

632
00:38:09,990 --> 00:38:07,990
hey a good read back and we'll keep you

633
00:38:19,750 --> 00:38:10,000
posted as we

634
00:38:24,870 --> 00:38:23,030
all right so a quick rundown of where we

635
00:38:27,349 --> 00:38:24,880
stand right now for bob and doug that

636
00:38:29,670 --> 00:38:27,359
was from the court jay aranja in the

637
00:38:31,589 --> 00:38:29,680
mission control room just behind us uh

638
00:38:34,150 --> 00:38:31,599
the core just as a reminder it's kind of

639
00:38:36,069 --> 00:38:34,160
like capcom if you followed our missions

640
00:38:38,069 --> 00:38:36,079
throughout our history that is really

641
00:38:39,910 --> 00:38:38,079
the sole person who's there to talk to

642
00:38:41,510 --> 00:38:39,920
bob and doug and be their advocate down

643
00:38:43,990 --> 00:38:41,520
here on the ground

644
00:38:46,870 --> 00:38:44,000
so as he said we are still on track for

645
00:38:48,310 --> 00:38:46,880
a splashdown today in pensacola

646
00:38:50,069 --> 00:38:48,320
he gave a couple of those weather

647
00:38:52,870 --> 00:38:50,079
details we're looking at wind speeds of

648
00:38:55,829 --> 00:38:52,880
about one knot so just around a mile and

649
00:38:57,589 --> 00:38:55,839
a half per hour and very calm seas out

650
00:38:59,109 --> 00:38:57,599
there weather was the thing we were

651
00:39:00,069 --> 00:38:59,119
really looking for

652
00:39:01,670 --> 00:39:00,079
and if you checked out some of the

653
00:39:03,430 --> 00:39:01,680
information we had online we were

654
00:39:05,589 --> 00:39:03,440
looking for wind speeds less than about

655
00:39:07,829 --> 00:39:05,599
10 miles an hour so we're well under

656
00:39:10,630 --> 00:39:07,839
that for this flash down today we ended

657
00:39:12,470 --> 00:39:10,640
up getting pretty spectacular weather

658
00:39:14,550 --> 00:39:12,480
conditions for this

659
00:39:16,230 --> 00:39:14,560
obviously some pretty nasty weather

660
00:39:18,550 --> 00:39:16,240
around florida right now that a lot of

661
00:39:20,310 --> 00:39:18,560
people are having to deal with um and

662
00:39:22,710 --> 00:39:20,320
three of our potential landing zones

663
00:39:24,390 --> 00:39:22,720
were actually in the path of that storm

664
00:39:26,630 --> 00:39:24,400
yeah you as you've heard just mentioned

665
00:39:28,710 --> 00:39:26,640
before tropical storm or hurricane as it

666
00:39:29,829 --> 00:39:28,720
was previously referred to before it got

667
00:39:32,150 --> 00:39:29,839
downgraded

668
00:39:34,310 --> 00:39:32,160
isaiah was creating a little bit of

669
00:39:36,710 --> 00:39:34,320
problem for us on the east coast of

670
00:39:38,550 --> 00:39:36,720
florida as like we mentioned before

671
00:39:40,390 --> 00:39:38,560
three of our potential landing sites

672
00:39:42,870 --> 00:39:40,400
were there on the east coast

673
00:39:44,790 --> 00:39:42,880
ruled out due to unfavorable weather due

674
00:39:46,790 --> 00:39:44,800
to that tropical storm

675
00:39:49,030 --> 00:39:46,800
but like we just mentioned the gulf of

676
00:39:50,630 --> 00:39:49,040
mexico is looking really good

677
00:39:51,589 --> 00:39:50,640
one mile an hour wind that's like

678
00:39:53,589 --> 00:39:51,599
nothing

679
00:39:55,430 --> 00:39:53,599
and with really small waves

680
00:39:57,990 --> 00:39:55,440
bob and doug will be very comfortable

681
00:39:59,510 --> 00:39:58,000
and safe whenever they do reach the

682
00:40:01,510 --> 00:39:59,520
atlantic ocean

683
00:40:03,910 --> 00:40:01,520
excuse me the gulf of mexico the other

684
00:40:05,910 --> 00:40:03,920
thing you heard called out there was a

685
00:40:07,589 --> 00:40:05,920
generator problem that we're having on

686
00:40:09,990 --> 00:40:07,599
the recovery vessel

687
00:40:11,750 --> 00:40:10,000
basically there are two generators and

688
00:40:14,550 --> 00:40:11,760
one of them is down currently so the

689
00:40:16,630 --> 00:40:14,560
team is working on a backup generator so

690
00:40:19,829 --> 00:40:16,640
that uh there is no single point failure

691
00:40:22,069 --> 00:40:19,839
on the from the generator aspect on the

692
00:40:24,550 --> 00:40:22,079
recovery ship so working that in line

693
00:40:27,190 --> 00:40:24,560
but all good news that everything will

694
00:40:29,349 --> 00:40:27,200
be in place on time for bob and doug

695
00:40:32,470 --> 00:40:29,359
splashdown which we're anticipating to

696
00:40:34,950 --> 00:40:32,480
be around 11 30 a.m pacific seems hard

697
00:40:37,430 --> 00:40:34,960
to believe that that's still so soon and

698
00:40:39,510 --> 00:40:37,440
yet so far away yeah right now

699
00:40:41,270 --> 00:40:39,520
still have a couple of hours but weather

700
00:40:42,950 --> 00:40:41,280
is going to continue to hold it looks

701
00:40:43,670 --> 00:40:42,960
like

702
00:40:47,829 --> 00:40:43,680
the

703
00:40:49,349 --> 00:40:47,839
eastern coast of florida

704
00:40:51,910 --> 00:40:49,359
has created some pretty favorable

705
00:40:53,750 --> 00:40:51,920
conditions for us in the gulf just to

706
00:40:56,550 --> 00:40:53,760
remind you we do

707
00:40:58,870 --> 00:40:56,560
undock only when we had both a prime and

708
00:41:01,190 --> 00:40:58,880
an alternate so we were able to get good

709
00:41:02,950 --> 00:41:01,200
weather we have several pairings

710
00:41:04,550 --> 00:41:02,960
since there are seven different landing

711
00:41:06,950 --> 00:41:04,560
zones you have multiple pairings that

712
00:41:09,030 --> 00:41:06,960
you can have so you could have pensacola

713
00:41:11,270 --> 00:41:09,040
as a prime in panama city as a prime or

714
00:41:12,710 --> 00:41:11,280
tampa as your alternate

715
00:41:15,510 --> 00:41:12,720
so you have a bunch of these different

716
00:41:16,630 --> 00:41:15,520
options and we had several pairs that

717
00:41:19,109 --> 00:41:16,640
were go

718
00:41:20,950 --> 00:41:19,119
at that final go-no-go meeting just

719
00:41:23,109 --> 00:41:20,960
about six hours before undocking

720
00:41:25,270 --> 00:41:23,119
yesterday the ones that we were able to

721
00:41:27,990 --> 00:41:25,280
select was pensacola for our prime and

722
00:41:30,150 --> 00:41:28,000
panama city for our alternate if for

723
00:41:32,790 --> 00:41:30,160
some reason we did have to wave off

724
00:41:35,349 --> 00:41:32,800
today panama city would likely be our

725
00:41:37,349 --> 00:41:35,359
alternate we still have about an hour a

726
00:41:39,030 --> 00:41:37,359
little less than an hour where dragon

727
00:41:40,150 --> 00:41:39,040
has the capability to change that

728
00:41:41,750 --> 00:41:40,160
alternate

729
00:41:43,829 --> 00:41:41,760
mid-flight

730
00:41:45,589 --> 00:41:43,839
if for some reason weather moved in on

731
00:41:47,910 --> 00:41:45,599
panama city and took it out of the

732
00:41:50,390 --> 00:41:47,920
equation but weather still looking good

733
00:41:52,230 --> 00:41:50,400
at both sites uh most importantly still

734
00:41:54,550 --> 00:41:52,240
looking good at our prime site today

735
00:41:56,950 --> 00:41:54,560
yeah like we mentioned before uh all of

736
00:41:59,750 --> 00:41:56,960
these sites are determined based on the

737
00:42:02,470 --> 00:41:59,760
fact that they have to be accessible uh

738
00:42:03,910 --> 00:42:02,480
so relatively close to shore by the

739
00:42:06,790 --> 00:42:03,920
recovery vessel

740
00:42:09,510 --> 00:42:06,800
and also close to medical facilities so

741
00:42:11,109 --> 00:42:09,520
that whenever bob and doug are

742
00:42:12,870 --> 00:42:11,119
taken off the

743
00:42:14,550 --> 00:42:12,880
off the vessel that they're able to be

744
00:42:17,109 --> 00:42:14,560
close to a hospital and medical

745
00:42:19,990 --> 00:42:17,119
treatment if necessary but like we said

746
00:42:21,670 --> 00:42:20,000
before there were seven potential sites

747
00:42:23,910 --> 00:42:21,680
three of them ruled out thanks to

748
00:42:26,550 --> 00:42:23,920
weather on the east coast

749
00:42:28,790 --> 00:42:26,560
and we are now targeting the gulf of

750
00:42:31,829 --> 00:42:28,800
mexico off the coast of pensacola

751
00:42:35,270 --> 00:42:31,839
florida as our primary landing site

752
00:42:36,870 --> 00:42:35,280
and once bob and doug splash down it'll

753
00:42:39,270 --> 00:42:36,880
a lot of things are going to happen in

754
00:42:40,630 --> 00:42:39,280
really quick succession just to make

755
00:42:42,230 --> 00:42:40,640
sure that we can get the capsule out of

756
00:42:44,630 --> 00:42:42,240
the water and get them out of the

757
00:42:46,550 --> 00:42:44,640
capsule just as rapidly as possible

758
00:42:47,589 --> 00:42:46,560
within minutes actually

759
00:42:50,069 --> 00:42:47,599
the

760
00:42:51,349 --> 00:42:50,079
teams here in mission control hawthorne

761
00:42:53,030 --> 00:42:51,359
will actually

762
00:42:54,630 --> 00:42:53,040
do a check on the vehicle systems

763
00:42:57,430 --> 00:42:54,640
following splashdown and they'll give

764
00:42:59,510 --> 00:42:57,440
the go to the recovery teams to proceed

765
00:43:02,069 --> 00:42:59,520
we expect that to be just within a

766
00:43:04,150 --> 00:43:02,079
minute or two of that splashdown

767
00:43:06,950 --> 00:43:04,160
the spacex recovery personnel will put

768
00:43:09,190 --> 00:43:06,960
two fast boats of smaller boats off of

769
00:43:11,510 --> 00:43:09,200
the prime recovery vessel which itself

770
00:43:13,270 --> 00:43:11,520
is about three nautical miles away or so

771
00:43:15,030 --> 00:43:13,280
from the splashdown point

772
00:43:17,190 --> 00:43:15,040
which is about a 30 minute journey for

773
00:43:19,430 --> 00:43:17,200
the boat at the speed it travels those

774
00:43:21,430 --> 00:43:19,440
two fast boats will hit the water and

775
00:43:22,710 --> 00:43:21,440
move in quickly on the capsule once they

776
00:43:24,470 --> 00:43:22,720
get the go

777
00:43:26,950 --> 00:43:24,480
one of the first jobs that they'll have

778
00:43:29,270 --> 00:43:26,960
is to go in and actually kind of sniff

779
00:43:31,109 --> 00:43:29,280
around the the capsule itself where

780
00:43:33,109 --> 00:43:31,119
they're looking for any trace signatures

781
00:43:36,069 --> 00:43:33,119
vapors of what's known as hypergolic

782
00:43:37,829 --> 00:43:36,079
fuels so dragon uses hypergolic fuels

783
00:43:40,470 --> 00:43:37,839
these are fuels that you don't need an

784
00:43:42,470 --> 00:43:40,480
ignition source to make them ignite

785
00:43:44,790 --> 00:43:42,480
basically just throwing them together

786
00:43:45,750 --> 00:43:44,800
will create a an explosion which is what

787
00:43:49,349 --> 00:43:45,760
a

788
00:43:50,950 --> 00:43:49,359
controlled explosion

789
00:43:53,430 --> 00:43:50,960
so they'll sniff around the capsule for

790
00:43:54,710 --> 00:43:53,440
any hypergolics as long as that comes

791
00:43:56,390 --> 00:43:54,720
back at negative

792
00:43:58,630 --> 00:43:56,400
they can move in and start rigging the

793
00:43:59,990 --> 00:43:58,640
capsule itself to get lifted up and i

794
00:44:02,069 --> 00:44:00,000
know that's going to be a pretty

795
00:44:04,069 --> 00:44:02,079
exciting operation to see yeah there

796
00:44:06,069 --> 00:44:04,079
were actually somebody climbing on top

797
00:44:08,150 --> 00:44:06,079
of the capsule itself to perform that

798
00:44:09,910 --> 00:44:08,160
rigging that individual is highly

799
00:44:12,069 --> 00:44:09,920
specialized and trained for that

800
00:44:14,470 --> 00:44:12,079
operation because as you can imagine

801
00:44:15,750 --> 00:44:14,480
climbing on top of an oddly shaped uh

802
00:44:18,630 --> 00:44:15,760
capsule

803
00:44:21,030 --> 00:44:18,640
in the ocean makes it wet and so having

804
00:44:23,190 --> 00:44:21,040
to get on top of there and secure the

805
00:44:25,990 --> 00:44:23,200
rigging in preparation for lifting onto

806
00:44:28,069 --> 00:44:26,000
the deck of the recovery ship uh that's

807
00:44:29,829 --> 00:44:28,079
a quite a specific job and that person

808
00:44:31,589 --> 00:44:29,839
has undergone hours and hours of

809
00:44:34,069 --> 00:44:31,599
training in order to perform those

810
00:44:37,109 --> 00:44:34,079
operations safely so once that is all

811
00:44:38,150 --> 00:44:37,119
done uh the excuse me the capsule will

812
00:44:40,710 --> 00:44:38,160
then be

813
00:44:43,190 --> 00:44:40,720
lifted hoisted up onto the deck of the

814
00:44:45,990 --> 00:44:43,200
recovery ship and then they'll be placed

815
00:44:47,109 --> 00:44:46,000
back down but the will open the side

816
00:44:47,990 --> 00:44:47,119
hatch so

817
00:44:50,390 --> 00:44:48,000
for

818
00:44:52,950 --> 00:44:50,400
international space station operations

819
00:44:55,589 --> 00:44:52,960
we use the forward hatch or the hatch on

820
00:44:58,550 --> 00:44:55,599
top of the capsule in order to ingress

821
00:45:00,710 --> 00:44:58,560
an egress for this particular operation

822
00:45:02,390 --> 00:45:00,720
of recovery they will actually be coming

823
00:45:04,230 --> 00:45:02,400
out of the side hatch

824
00:45:06,150 --> 00:45:04,240
once that side hatch is opened our

825
00:45:07,589 --> 00:45:06,160
flight surgeon will pop his head in and

826
00:45:09,750 --> 00:45:07,599
make sure everything is good and that

827
00:45:11,990 --> 00:45:09,760
they're both feeling good uh and then

828
00:45:14,390 --> 00:45:12,000
we'll pull bob and doug out and have

829
00:45:16,710 --> 00:45:14,400
them proceed to the medical tent so

830
00:45:19,430 --> 00:45:16,720
something about these uh recovery ships

831
00:45:20,630 --> 00:45:19,440
they're actually fully equipped medical

832
00:45:22,710 --> 00:45:20,640
facilities

833
00:45:24,390 --> 00:45:22,720
bob and doug will both go through

834
00:45:25,829 --> 00:45:24,400
a little bit of a screening once once

835
00:45:27,829 --> 00:45:25,839
they're on deck

836
00:45:30,550 --> 00:45:27,839
and then after that they'll actually hop

837
00:45:33,109 --> 00:45:30,560
on an airplane and get sent back to

838
00:45:35,589 --> 00:45:33,119
excuse me yeah get sent back to texas

839
00:45:37,430 --> 00:45:35,599
yeah for most of our

840
00:45:39,190 --> 00:45:37,440
splashdown locations

841
00:45:42,710 --> 00:45:39,200
the crew gets taken off the boat in a

842
00:45:45,190 --> 00:45:42,720
helicopter there is one specific landing

843
00:45:47,589 --> 00:45:45,200
zone and it's the one off cape canaveral

844
00:45:48,309 --> 00:45:47,599
which we were at kind of a further one

845
00:45:51,510 --> 00:45:48,319
for

846
00:45:54,150 --> 00:45:51,520
demo one demo one uh we splashed down a

847
00:45:55,349 --> 00:45:54,160
little over 200 kilometer or 200 miles

848
00:45:57,190 --> 00:45:55,359
offshore

849
00:46:00,870 --> 00:45:57,200
there's a closer one for crude landings

850
00:46:03,030 --> 00:46:00,880
only about 24 miles offshore but

851
00:46:05,430 --> 00:46:03,040
for all of our other landing zones it

852
00:46:08,069 --> 00:46:05,440
takes probably several hours for the

853
00:46:09,430 --> 00:46:08,079
boat to get back into port so spacex

854
00:46:12,470 --> 00:46:09,440
does have the option to land a

855
00:46:14,470 --> 00:46:12,480
helicopter on the recovery vessel itself

856
00:46:16,470 --> 00:46:14,480
to then move the crew members

857
00:46:18,630 --> 00:46:16,480
back for a much quicker

858
00:46:21,910 --> 00:46:18,640
return to dry land loading onto that

859
00:46:23,910 --> 00:46:21,920
nasa plane and returning to houston

860
00:46:25,510 --> 00:46:23,920
we get a lot of questions about how

861
00:46:27,589 --> 00:46:25,520
we're keeping the crew safe how we're

862
00:46:30,230 --> 00:46:27,599
keeping the crew healthy we have a lot

863
00:46:32,470 --> 00:46:30,240
of very strict protocols in place any

864
00:46:34,470 --> 00:46:32,480
time we send people into space and

865
00:46:37,270 --> 00:46:34,480
anytime we bring them home

866
00:46:38,950 --> 00:46:37,280
as space flight can be pretty harsh on

867
00:46:41,270 --> 00:46:38,960
the body even with all of the

868
00:46:43,270 --> 00:46:41,280
countermeasures that we have developed

869
00:46:45,349 --> 00:46:43,280
a lot of astronauts will come back

870
00:46:47,270 --> 00:46:45,359
immunocompromised

871
00:46:49,349 --> 00:46:47,280
and so we really just have to make sure

872
00:46:51,430 --> 00:46:49,359
we're taking very good care of them

873
00:46:54,309 --> 00:46:51,440
especially in our current climate with

874
00:46:55,990 --> 00:46:54,319
coronavirus we've made

875
00:46:58,470 --> 00:46:56,000
some additional

876
00:47:00,230 --> 00:46:58,480
restrictions and requirements in place

877
00:47:01,589 --> 00:47:00,240
for all of our recovery personnel that

878
00:47:04,069 --> 00:47:01,599
are going to be on the boat all have

879
00:47:07,030 --> 00:47:04,079
gone through some isolation uh and

880
00:47:08,710 --> 00:47:07,040
testing for uh coronavirus before

881
00:47:10,150 --> 00:47:08,720
heading out to sea and we're doing this

882
00:47:12,710 --> 00:47:10,160
anybody that's going to be in close

883
00:47:15,109 --> 00:47:12,720
contact with the crew we're making sure

884
00:47:16,309 --> 00:47:15,119
that we have countermeasures in place to

885
00:47:18,470 --> 00:47:16,319
make sure

886
00:47:20,470 --> 00:47:18,480
that they are screened and that the crew

887
00:47:22,230 --> 00:47:20,480
is being kept healthy once they get back

888
00:47:24,309 --> 00:47:22,240
to houston they'll be able to reunite

889
00:47:26,549 --> 00:47:24,319
with families and then eventually go

890
00:47:28,549 --> 00:47:26,559
home or go to crew quarters there in

891
00:47:30,470 --> 00:47:28,559
houston yeah so they're certainly

892
00:47:33,589 --> 00:47:30,480
looking forward to having their family

893
00:47:35,349 --> 00:47:33,599
reunion today hopefully you caught their

894
00:47:38,390 --> 00:47:35,359
wake-up message earlier this morning

895
00:47:40,470 --> 00:47:38,400
messages from both of their sons having

896
00:47:42,069 --> 00:47:40,480
them wake up it sounds like there is a

897
00:47:43,990 --> 00:47:42,079
puppy in the future for one of our

898
00:47:46,230 --> 00:47:44,000
astronaut families so

899
00:47:47,829 --> 00:47:46,240
good luck with that

900
00:47:50,390 --> 00:47:47,839
but something else to note about the

901
00:47:52,790 --> 00:47:50,400
recovery process is that all of this is

902
00:47:54,470 --> 00:47:52,800
going to take about an hour to do

903
00:47:56,230 --> 00:47:54,480
we want to make sure that

904
00:47:59,030 --> 00:47:56,240
we get the capsule out of the water as

905
00:47:59,829 --> 00:47:59,040
quickly as possible but safely as well

906
00:48:01,829 --> 00:47:59,839
as

907
00:48:04,069 --> 00:48:01,839
opening the hatch and and having bob and

908
00:48:06,549 --> 00:48:04,079
doug come out and wheeled into the the

909
00:48:09,109 --> 00:48:06,559
medical tents there so all in all it'll

910
00:48:10,630 --> 00:48:09,119
take about 60 minutes or so and we're

911
00:48:12,470 --> 00:48:10,640
certainly looking forward to seeing all

912
00:48:13,990 --> 00:48:12,480
that happen live

913
00:48:17,190 --> 00:48:14,000
but backing up a little bit to the

914
00:48:19,670 --> 00:48:17,200
events that we have coming up sooner

915
00:48:21,910 --> 00:48:19,680
we will be performing a couple of

916
00:48:23,190 --> 00:48:21,920
maneuvers in order to get the the

917
00:48:26,069 --> 00:48:23,200
vehicle

918
00:48:28,470 --> 00:48:26,079
in place and ready for its deorbit burn

919
00:48:30,470 --> 00:48:28,480
uh that will take place and then we will

920
00:48:32,950 --> 00:48:30,480
close the nose cone in order to protect

921
00:48:35,109 --> 00:48:32,960
the that top hatch and then shortly

922
00:48:37,270 --> 00:48:35,119
after that the vehicle will begin to

923
00:48:39,109 --> 00:48:37,280
re-enter the earth's atmosphere and then

924
00:48:40,950 --> 00:48:39,119
we will have parachute deployment so all

925
00:48:44,230 --> 00:48:40,960
of that is going to be happening around

926
00:48:46,950 --> 00:48:44,240
11 30 a.m pacific so be sure to stick

927
00:48:49,910 --> 00:48:46,960
around as we prepare to step into the

928
00:48:52,390 --> 00:48:49,920
really exciting events of splashdown day

929
00:48:54,790 --> 00:48:52,400
and throughout the morning and

930
00:48:56,150 --> 00:48:54,800
leah and shiva were doing a great job of

931
00:48:58,549 --> 00:48:56,160
it overnight we're going to be taking

932
00:49:00,309 --> 00:48:58,559
your questions on social media if you

933
00:49:02,950 --> 00:49:00,319
have a question for us jump on twitter

934
00:49:04,470 --> 00:49:02,960
use the hashtag asknasa and we'll try to

935
00:49:06,069 --> 00:49:04,480
get through as many as we can today we

936
00:49:08,230 --> 00:49:06,079
do have a couple of hours until we

937
00:49:09,430 --> 00:49:08,240
really start picking up the operations

938
00:49:11,190 --> 00:49:09,440
so we should have a chance to get

939
00:49:13,349 --> 00:49:11,200
through quite a few i will take one

940
00:49:15,589 --> 00:49:13,359
right now this one comes from mogster

941
00:49:19,349 --> 00:49:15,599
who wants to know roughly what speed are

942
00:49:21,510 --> 00:49:19,359
bob and doug going at splashdown and

943
00:49:23,829 --> 00:49:21,520
it's quite a slow down yeah it certainly

944
00:49:26,950 --> 00:49:23,839
is at the point of splashdown they'll be

945
00:49:29,030 --> 00:49:26,960
going about 15 or 16 miles per hour so

946
00:49:30,710 --> 00:49:29,040
that's about the speed that you go in

947
00:49:33,510 --> 00:49:30,720
your car whenever you're driving through

948
00:49:37,030 --> 00:49:33,520
a school zone so that slow is a house

949
00:49:39,510 --> 00:49:37,040
low that is the speed that they'll be

950
00:49:43,190 --> 00:49:39,520
landing in the gulf of mexico

951
00:49:45,030 --> 00:49:43,200
a slow down from 350 miles per hour as

952
00:49:48,230 --> 00:49:45,040
they ran to the earth's atmosphere and

953
00:49:50,309 --> 00:49:48,240
that's a slow down from 17 500 miles per

954
00:49:51,829 --> 00:49:50,319
hour that they were traveling whenever

955
00:49:54,870 --> 00:49:51,839
they were orbiting earth with the

956
00:49:57,430 --> 00:49:54,880
international space station so they are

957
00:49:58,790 --> 00:49:57,440
yeah very very drastic indeed uh we have

958
00:50:01,910 --> 00:49:58,800
another

959
00:50:04,230 --> 00:50:01,920
twitter question coming to us

960
00:50:06,230 --> 00:50:04,240
it says i saw a video that bob and

961
00:50:08,309 --> 00:50:06,240
doug's suits were being pressurized in

962
00:50:10,870 --> 00:50:08,319
dragon will it be pressurized during

963
00:50:13,349 --> 00:50:10,880
re-entry that's a great question

964
00:50:15,510 --> 00:50:13,359
the the pressurization that you saw

965
00:50:18,150 --> 00:50:15,520
would have been during a leak check that

966
00:50:19,910 --> 00:50:18,160
is the only point in which the the

967
00:50:22,069 --> 00:50:19,920
spacesuits are pressurized as whenever

968
00:50:24,390 --> 00:50:22,079
we're doing a leak check we do those

969
00:50:26,150 --> 00:50:24,400
leak checks right after the crew puts

970
00:50:28,630 --> 00:50:26,160
their spacesuits on just to make sure

971
00:50:30,230 --> 00:50:28,640
that everything is zipped up properly

972
00:50:31,910 --> 00:50:30,240
because those zippers are very

973
00:50:33,589 --> 00:50:31,920
specialized in order to maintain that

974
00:50:35,109 --> 00:50:33,599
pressurization

975
00:50:37,430 --> 00:50:35,119
so if you've got to make sure that

976
00:50:39,430 --> 00:50:37,440
everything is on right and everything is

977
00:50:40,870 --> 00:50:39,440
zipped up and we apply that

978
00:50:42,710 --> 00:50:40,880
pressurization in order to make sure

979
00:50:44,790 --> 00:50:42,720
that everything is fitting properly we

980
00:50:46,710 --> 00:50:44,800
then depressurize and they're able to

981
00:50:49,270 --> 00:50:46,720
lift the visors on their helmets once

982
00:50:51,349 --> 00:50:49,280
again uh and at that point the suit is

983
00:50:54,069 --> 00:50:51,359
at the same pressure as the atmosphere

984
00:50:56,150 --> 00:50:54,079
within the cabin itself yeah we'll only

985
00:50:58,710 --> 00:50:56,160
pressurize those suits as kate said

986
00:51:01,109 --> 00:50:58,720
either when we're testing it or if we

987
00:51:03,030 --> 00:51:01,119
are in a situation where

988
00:51:05,829 --> 00:51:03,040
the cabin loses pressure so you can kind

989
00:51:07,589 --> 00:51:05,839
of think uh on airlines they have

990
00:51:09,430 --> 00:51:07,599
procedures if the cabin loses pressure

991
00:51:11,750 --> 00:51:09,440
where they give you oxygen

992
00:51:13,670 --> 00:51:11,760
space a much more extreme environment

993
00:51:15,270 --> 00:51:13,680
where not only do we need to provide

994
00:51:16,790 --> 00:51:15,280
them oxygen but we need to give them a

995
00:51:18,069 --> 00:51:16,800
pressurized environment and the suit's

996
00:51:19,990 --> 00:51:18,079
able to do that

997
00:51:23,589 --> 00:51:20,000
so they just leave one of the zippers

998
00:51:25,190 --> 00:51:23,599
open during the the reentry phase and if

999
00:51:27,270 --> 00:51:25,200
they were in a situation where they're

1000
00:51:28,309 --> 00:51:27,280
in a deep press they can pressurize it

1001
00:51:30,069 --> 00:51:28,319
up

1002
00:51:32,230 --> 00:51:30,079
all right we'll do one more we got one

1003
00:51:34,390 --> 00:51:32,240
from movie marathon who wants to know is

1004
00:51:35,910 --> 00:51:34,400
someone who needs my morning caffeine

1005
00:51:38,309 --> 00:51:35,920
wondering if bob and doug can start

1006
00:51:41,349 --> 00:51:38,319
their day with a hot

1007
00:51:43,670 --> 00:51:41,359
hot pouch of coffee

1008
00:51:45,990 --> 00:51:43,680
that is also a good question i am the

1009
00:51:48,390 --> 00:51:46,000
same i like my morning coffee

1010
00:51:50,390 --> 00:51:48,400
unfortunately there is no ability for

1011
00:51:52,710 --> 00:51:50,400
bob and doug to heat their food or

1012
00:51:56,069 --> 00:51:52,720
beverage in the dragon capsule

1013
00:51:58,069 --> 00:51:56,079
so if coffee is part of the the

1014
00:52:00,390 --> 00:51:58,079
packaging the packaged food that they

1015
00:52:03,190 --> 00:52:00,400
have because everything is pre-packaged

1016
00:52:05,589 --> 00:52:03,200
it is vacuum sealed so that it's easy to

1017
00:52:07,349 --> 00:52:05,599
stow and easy to consume

1018
00:52:10,069 --> 00:52:07,359
the coffee that they would have would be

1019
00:52:12,309 --> 00:52:10,079
at room temperature coffee so might not

1020
00:52:13,990 --> 00:52:12,319
be the ideal type of coffee but it's

1021
00:52:17,349 --> 00:52:14,000
safe to say that they'll be able to get

1022
00:52:19,349 --> 00:52:17,359
their hot coffee in less than 24 hours

1023
00:52:21,750 --> 00:52:19,359
all right so again keep sending in those

1024
00:52:23,430 --> 00:52:21,760
questions using the hashtag asknow so

1025
00:52:25,510 --> 00:52:23,440
we'll continue to get them throughout

1026
00:52:26,790 --> 00:52:25,520
our show this morning we do need to take

1027
00:52:28,790 --> 00:52:26,800
a moment though for those of you

1028
00:52:30,470 --> 00:52:28,800
watching on youtube take a look at the

1029
00:52:32,390 --> 00:52:30,480
comment section down below we're going

1030
00:52:34,870 --> 00:52:32,400
to be switching over our links we need

1031
00:52:36,790 --> 00:52:34,880
to stop the broadcast momentarily on

1032
00:52:38,710 --> 00:52:36,800
youtube and start a new one just to make

1033
00:52:41,270 --> 00:52:38,720
sure it gets archived correctly so we'll

1034
00:52:44,230 --> 00:52:41,280
be back live at that new location very

1035
00:52:45,670 --> 00:52:44,240
shortly if you're watching on nasa tv no

1036
00:52:47,109 --> 00:52:45,680
changes needed coverage stays

1037
00:52:49,190 --> 00:52:47,119
interrupted all the way through

1038
00:57:27,190 --> 00:52:49,200
splashdown today you won't notice a

1039
00:57:32,069 --> 00:57:29,349
hello and welcome to our live coverage

1040
00:57:33,990 --> 00:57:32,079
of spacex demo 2 mission

1041
00:57:36,150 --> 00:57:34,000
we are excited to be bringing you live

1042
00:57:38,630 --> 00:57:36,160
coverage here from spacex headquarters

1043
00:57:41,510 --> 00:57:38,640
in hawthorne california my name is kate

1044
00:57:45,349 --> 00:57:41,520
tice a senior certification engineer and

1045
00:57:47,030 --> 00:57:45,359
it has been an exciting 24 hours

1046
00:57:48,870 --> 00:57:47,040
backtracking a little bit bob and doug

1047
00:57:51,430 --> 00:57:48,880
launched the international space station

1048
00:57:52,950 --> 00:57:51,440
just two months ago and earlier today

1049
00:57:55,270 --> 00:57:52,960
departed from the international space

1050
00:57:56,870 --> 00:57:55,280
station and began their journey home

1051
00:57:59,750 --> 00:57:56,880
they've completed all the departure

1052
00:58:02,069 --> 00:57:59,760
burns and they are now awake and ready

1053
00:58:04,789 --> 00:58:02,079
to begin the day so a couple of events

1054
00:58:07,190 --> 00:58:04,799
that we have upcoming at 10 48 a.m

1055
00:58:09,589 --> 00:58:07,200
pacific time we will do what's known as

1056
00:58:12,309 --> 00:58:09,599
slew to trunk jettison attitude and

1057
00:58:14,549 --> 00:58:12,319
that's basically positioning the vehicle

1058
00:58:17,670 --> 00:58:14,559
in proper and it's proper place in order

1059
00:58:19,510 --> 00:58:17,680
to jettison that trunk we want to expose

1060
00:58:22,549 --> 00:58:19,520
the heat shield in preparation for

1061
00:58:24,870 --> 00:58:22,559
capsule re-entry so we will we will

1062
00:58:28,309 --> 00:58:24,880
separate from the trunk and that will be

1063
00:58:30,710 --> 00:58:28,319
occurring at 10 51 a.m pacific time we

1064
00:58:33,190 --> 00:58:30,720
will then slow or maneuver to deorbit

1065
00:58:35,430 --> 00:58:33,200
burn attitude and that deorbit burn is

1066
00:58:37,829 --> 00:58:35,440
what is going to really place dragon on

1067
00:58:39,430 --> 00:58:37,839
its final trajectory back to earth

1068
00:58:42,470 --> 00:58:39,440
yeah once the engines fire on that

1069
00:58:44,789 --> 00:58:42,480
deorbit burn dragon is committed to

1070
00:58:47,190 --> 00:58:44,799
returning home and that's what really

1071
00:58:49,270 --> 00:58:47,200
adjusts their orbit to line them up

1072
00:58:52,230 --> 00:58:49,280
straight with that splashdown zone right

1073
00:58:54,309 --> 00:58:52,240
off the coast of pensacola and so we are

1074
00:58:56,069 --> 00:58:54,319
expecting that the orbit burn

1075
00:58:57,750 --> 00:58:56,079
times have stayed pretty much

1076
00:58:59,349 --> 00:58:57,760
solid throughout all the different burns

1077
00:59:01,190 --> 00:58:59,359
that dragon has done since it's left the

1078
00:59:03,910 --> 00:59:01,200
international space station we're

1079
00:59:05,630 --> 00:59:03,920
expecting that burn at about 10 56 a.m

1080
00:59:08,870 --> 00:59:05,640
pacific uh

1081
00:59:11,349 --> 00:59:08,880
1756 gmt we'll try to give you guys a

1082
00:59:13,910 --> 00:59:11,359
couple of split times here that deorbit

1083
00:59:16,549 --> 00:59:13,920
burns expected to last 11 minutes and 22

1084
00:59:18,470 --> 00:59:16,559
seconds it's executed primarily using

1085
00:59:20,710 --> 00:59:18,480
the forward bulkhead thrusters on the

1086
00:59:22,870 --> 00:59:20,720
very top of dragon there are four of

1087
00:59:24,789 --> 00:59:22,880
them and it'll alternate between a

1088
00:59:27,510 --> 00:59:24,799
couple of them during that deorbit burn

1089
00:59:29,109 --> 00:59:27,520
also using a number of the 12 service

1090
00:59:31,270 --> 00:59:29,119
section dracos just to maintain the

1091
00:59:33,589 --> 00:59:31,280
proper attitude while those engines are

1092
00:59:35,190 --> 00:59:33,599
firing it's the longest burn of dragon's

1093
00:59:37,190 --> 00:59:35,200
trip home and again that's what really

1094
00:59:39,510 --> 00:59:37,200
commits them once that the orbit burn is

1095
00:59:41,750 --> 00:59:39,520
complete they are rear they are

1096
00:59:43,910 --> 00:59:41,760
re-entering the earth's atmosphere

1097
00:59:46,069 --> 00:59:43,920
so after the completion of that deorbit

1098
00:59:48,630 --> 00:59:46,079
burn dragon will look to close its nose

1099
00:59:54,069 --> 00:59:48,640
cone that's targeted to come at about 11

1100
00:59:55,910 --> 00:59:54,079
11 a.m pacific time uh or 1811 gmt and

1101
00:59:58,549 --> 00:59:55,920
closing up that nose cone is just done

1102
01:00:00,710 --> 00:59:58,559
to protect the very top of dragon where

1103
01:00:03,030 --> 01:00:00,720
you have the docking ring some guidance

1104
01:00:05,670 --> 01:00:03,040
navigation and control sensors and those

1105
01:00:08,309 --> 01:00:05,680
four forward bulkhead thrusters from the

1106
01:00:11,349 --> 01:00:08,319
heat of reentry this just helps to aid

1107
01:00:13,430 --> 01:00:11,359
in dragon's reusability this capsule in

1108
01:00:15,670 --> 01:00:13,440
particular already slated for another

1109
01:00:16,789 --> 01:00:15,680
mission it's going to be flying the crew

1110
01:00:18,470 --> 01:00:16,799
2 crew

1111
01:00:20,309 --> 01:00:18,480
next year

1112
01:00:21,910 --> 01:00:20,319
after we really start to re-enter the

1113
01:00:23,430 --> 01:00:21,920
earth's atmosphere things will start

1114
01:00:26,390 --> 01:00:23,440
heating up the dragon capsule

1115
01:00:28,470 --> 01:00:26,400
experiencing up to 3 500 degrees during

1116
01:00:30,549 --> 01:00:28,480
this reentry and that'll build up a

1117
01:00:33,109 --> 01:00:30,559
plasma around the spacecraft and that'll

1118
01:00:35,030 --> 01:00:33,119
result in what we call a coms blackout

1119
01:00:37,109 --> 01:00:35,040
there will be about six minutes where we

1120
01:00:39,109 --> 01:00:37,119
can't talk to the crew onboard dragon

1121
01:00:40,950 --> 01:00:39,119
and we can't get any telemetry or data

1122
01:00:42,390 --> 01:00:40,960
from the vehicle and we can't send any

1123
01:00:44,309 --> 01:00:42,400
commands from the ground

1124
01:00:45,990 --> 01:00:44,319
this is expected and this is something

1125
01:00:48,150 --> 01:00:46,000
that's common in spacecraft when you're

1126
01:00:49,990 --> 01:00:48,160
generating that much heat it tends to

1127
01:00:52,390 --> 01:00:50,000
interfere with those sensitive radio

1128
01:00:54,710 --> 01:00:52,400
systems so we're expecting that to last

1129
01:00:56,630 --> 01:00:54,720
about six minutes dragon will continue

1130
01:00:59,030 --> 01:00:56,640
flying itself using its three flight

1131
01:01:00,789 --> 01:00:59,040
computers and the draco thrusters on the

1132
01:01:03,270 --> 01:01:00,799
service section to maintain a very

1133
01:01:05,270 --> 01:01:03,280
precise attitude as it continues towards

1134
01:01:06,470 --> 01:01:05,280
its flash down point off the coast of

1135
01:01:08,390 --> 01:01:06,480
pensacola

1136
01:01:10,069 --> 01:01:08,400
in the middle of that coms blackout

1137
01:01:11,990 --> 01:01:10,079
we'll have something called entry

1138
01:01:13,589 --> 01:01:12,000
interface that's when dragon's low

1139
01:01:16,950 --> 01:01:13,599
enough in the atmosphere now that it's

1140
01:01:18,549 --> 01:01:16,960
experiencing aerodynamic effects now

1141
01:01:21,109 --> 01:01:18,559
when you're flying around in the gravity

1142
01:01:22,870 --> 01:01:21,119
of space you don't experience lift drag

1143
01:01:24,150 --> 01:01:22,880
things like that that you have to worry

1144
01:01:26,630 --> 01:01:24,160
about once you're re-entering the

1145
01:01:28,870 --> 01:01:26,640
earth's atmosphere and once they get low

1146
01:01:30,549 --> 01:01:28,880
enough it's time for parachutes yeah so

1147
01:01:33,109 --> 01:01:30,559
first we're going to deploy our drogue

1148
01:01:35,109 --> 01:01:33,119
parachutes these are intended to

1149
01:01:38,390 --> 01:01:35,119
initially sort of slow the vehicle down

1150
01:01:40,150 --> 01:01:38,400
but also stabilize it so that a just two

1151
01:01:41,990 --> 01:01:40,160
minute or one minute after those drogue

1152
01:01:44,230 --> 01:01:42,000
shoots deploy we'll then release the

1153
01:01:46,470 --> 01:01:44,240
main parachutes so we'll have four

1154
01:01:49,030 --> 01:01:46,480
beautiful orange and white parachutes

1155
01:01:51,430 --> 01:01:49,040
and those will also continue to to slow

1156
01:01:54,470 --> 01:01:51,440
the castle down significantly

1157
01:01:55,750 --> 01:01:54,480
actually just to a mere 15 or 16 miles

1158
01:01:57,670 --> 01:01:55,760
per hour

1159
01:02:00,230 --> 01:01:57,680
as it splashes down in the gulf of

1160
01:02:04,870 --> 01:02:00,240
mexico that splashdown will will occur

1161
01:02:07,270 --> 01:02:04,880
at 11 48 a.m pacific or 1848

1162
01:02:09,190 --> 01:02:07,280
utc and

1163
01:02:11,270 --> 01:02:09,200
it's it's we're coming up to that here

1164
01:02:13,109 --> 01:02:11,280
in a few hours so be sure to stick with

1165
01:02:15,270 --> 01:02:13,119
us as we will be bringing you coverage

1166
01:02:17,109 --> 01:02:15,280
uh all the way through that splashdown

1167
01:02:19,589 --> 01:02:17,119
in addition to the recovery operations

1168
01:02:22,470 --> 01:02:19,599
which you know if for our long-time

1169
01:02:24,390 --> 01:02:22,480
spacex fans uh they're

1170
01:02:26,390 --> 01:02:24,400
the recovery team is really one that we

1171
01:02:29,349 --> 01:02:26,400
haven't had a chance to showcase really

1172
01:02:31,109 --> 01:02:29,359
since the last demo one mission uh and

1173
01:02:34,069 --> 01:02:31,119
so it's really great to see this new

1174
01:02:35,750 --> 01:02:34,079
team in action uh and and being able to

1175
01:02:37,109 --> 01:02:35,760
perform live all of the stuff that

1176
01:02:39,430 --> 01:02:37,119
they've been rehearsing with bob and

1177
01:02:42,230 --> 01:02:39,440
doug for the last couple of years yeah

1178
01:02:44,630 --> 01:02:42,240
we basically did a test run of this

1179
01:02:45,510 --> 01:02:44,640
flight a little over a year ago at demo

1180
01:02:46,870 --> 01:02:45,520
one

1181
01:02:48,870 --> 01:02:46,880
and kate and i were here to do the

1182
01:02:49,829 --> 01:02:48,880
splashdown for that one another early

1183
01:02:53,510 --> 01:02:49,839
morning

1184
01:02:55,430 --> 01:02:53,520
a little bit different spacex actually

1185
01:02:57,750 --> 01:02:55,440
had both of its recovery ships out in

1186
01:02:59,829 --> 01:02:57,760
the landing zone for dm1 both the go

1187
01:03:00,630 --> 01:02:59,839
navigator and the ghost searcher

1188
01:03:02,789 --> 01:03:00,640
for

1189
01:03:04,950 --> 01:03:02,799
actual operations though those boats are

1190
01:03:07,510 --> 01:03:04,960
split up the go navigator stays in the

1191
01:03:09,829 --> 01:03:07,520
gulf of mexico at least for right now

1192
01:03:12,150 --> 01:03:09,839
and it's responsible for any splashdowns

1193
01:03:14,789 --> 01:03:12,160
at the four sites in the gulf those are

1194
01:03:15,910 --> 01:03:14,799
pensacola panama city tallahassee and

1195
01:03:18,470 --> 01:03:15,920
tampa

1196
01:03:20,390 --> 01:03:18,480
and then the go searcher stays over on

1197
01:03:22,470 --> 01:03:20,400
the atlantic side for anything in the

1198
01:03:24,470 --> 01:03:22,480
cape jacksonville and the one that i'm

1199
01:03:25,990 --> 01:03:24,480
forgetting

1200
01:03:28,309 --> 01:03:26,000
i'll look it up

1201
01:03:30,069 --> 01:03:28,319
but those two boats are split up at any

1202
01:03:32,549 --> 01:03:30,079
time one of them will be primed for the

1203
01:03:35,589 --> 01:03:32,559
recovery operations and there are about

1204
01:03:37,750 --> 01:03:35,599
a little over 40 people on that ship to

1205
01:03:39,910 --> 01:03:37,760
actually recover the dragon spacecraft

1206
01:03:42,710 --> 01:03:39,920
and bob and doug and it's a co it's a

1207
01:03:44,309 --> 01:03:42,720
spacex and nasa joint team with a lot of

1208
01:03:46,390 --> 01:03:44,319
different personnel on board you have

1209
01:03:48,789 --> 01:03:46,400
people that are

1210
01:03:50,950 --> 01:03:48,799
experts in the dragon capsule itself you

1211
01:03:51,670 --> 01:03:50,960
have the ship's crew you have a number

1212
01:03:53,510 --> 01:03:51,680
of

1213
01:03:55,109 --> 01:03:53,520
people from the medical community

1214
01:03:57,430 --> 01:03:55,119
doctors from both spacex and flight

1215
01:03:59,270 --> 01:03:57,440
surgeons from nasa nurses

1216
01:04:01,109 --> 01:03:59,280
and then you also have cargo specialists

1217
01:04:04,630 --> 01:04:01,119
on board as dragon's bringing some cargo

1218
01:04:06,069 --> 01:04:04,640
home yeah so if you followed our uh our

1219
01:04:07,589 --> 01:04:06,079
our missions to the international space

1220
01:04:10,150 --> 01:04:07,599
station previously you might hear us

1221
01:04:12,150 --> 01:04:10,160
refer to as the maneuvering of dragon

1222
01:04:14,630 --> 01:04:12,160
around the station as a carefully

1223
01:04:17,750 --> 01:04:14,640
choreographed dance the recovery

1224
01:04:19,750 --> 01:04:17,760
operations are just like that as well

1225
01:04:22,230 --> 01:04:19,760
whenever it comes to

1226
01:04:24,870 --> 01:04:22,240
recovering the crew safety is the number

1227
01:04:26,470 --> 01:04:24,880
one priority for not only the astronauts

1228
01:04:28,789 --> 01:04:26,480
but the recovery team and all

1229
01:04:31,349 --> 01:04:28,799
individuals on board that recovery ship

1230
01:04:33,190 --> 01:04:31,359
as well so while there are 40 or so

1231
01:04:35,670 --> 01:04:33,200
people on board there definitely won't

1232
01:04:38,470 --> 01:04:35,680
be 40 people on deck

1233
01:04:40,150 --> 01:04:38,480
it'll be a strict limitation to the

1234
01:04:43,109 --> 01:04:40,160
personnel that are in the active

1235
01:04:45,029 --> 01:04:43,119
recovery operations that will be on the

1236
01:04:47,750 --> 01:04:45,039
on the deck on the recovery deck of of

1237
01:04:50,069 --> 01:04:47,760
the ship as the as the dragon capsule is

1238
01:04:51,190 --> 01:04:50,079
being lifted out of the water and into

1239
01:04:53,109 --> 01:04:51,200
the nest

1240
01:04:54,630 --> 01:04:53,119
so i'm really excited to be able to see

1241
01:04:56,230 --> 01:04:54,640
that firsthand

1242
01:04:57,829 --> 01:04:56,240
we will be like i said before we'll be

1243
01:05:01,910 --> 01:04:57,839
bringing you that coverage all the way

1244
01:05:03,589 --> 01:05:01,920
through and uh after bob and doug are

1245
01:05:05,349 --> 01:05:03,599
brought out of the dragon capsule so

1246
01:05:07,750 --> 01:05:05,359
once once the dragon capsule is placed

1247
01:05:09,750 --> 01:05:07,760
onto the recovery vessel in that nest

1248
01:05:12,069 --> 01:05:09,760
our flight surgeon will pop his head in

1249
01:05:14,710 --> 01:05:12,079
and make sure that everything is looking

1250
01:05:17,430 --> 01:05:14,720
and feeling good with our astronauts our

1251
01:05:19,829 --> 01:05:17,440
space dads and we will then have them

1252
01:05:21,750 --> 01:05:19,839
exit the capsule through that side hatch

1253
01:05:23,750 --> 01:05:21,760
we will wheel them into the medical

1254
01:05:25,990 --> 01:05:23,760
tents and they'll then get their

1255
01:05:28,470 --> 01:05:26,000
in-depth medical review with the with

1256
01:05:30,390 --> 01:05:28,480
the medical team and at which point they

1257
01:05:32,710 --> 01:05:30,400
will then hop on a helicopter and head

1258
01:05:35,510 --> 01:05:32,720
back to texas yeah and i mean all of

1259
01:05:37,990 --> 01:05:35,520
that is supposed to unfold in just about

1260
01:05:39,750 --> 01:05:38,000
an hour following splashdown within

1261
01:05:41,510 --> 01:05:39,760
minutes of dragon

1262
01:05:43,510 --> 01:05:41,520
hitting down in the water a lot of

1263
01:05:45,430 --> 01:05:43,520
things will happen simultaneously the

1264
01:05:46,630 --> 01:05:45,440
dragon capsule itself takes a number of

1265
01:05:48,549 --> 01:05:46,640
automatic

1266
01:05:50,470 --> 01:05:48,559
steps as soon as it detects that it's

1267
01:05:51,910 --> 01:05:50,480
splashed down one of the first things

1268
01:05:54,710 --> 01:05:51,920
that it does

1269
01:05:56,870 --> 01:05:54,720
will be to detach the parachutes

1270
01:05:58,390 --> 01:05:56,880
as once you're splashed down you don't

1271
01:05:59,430 --> 01:05:58,400
need them to slow you down anymore

1272
01:06:00,870 --> 01:05:59,440
obviously

1273
01:06:02,549 --> 01:06:00,880
and you don't want them dragging you

1274
01:06:04,549 --> 01:06:02,559
through the water so dragon will

1275
01:06:06,309 --> 01:06:04,559
automatically cut those main parachutes

1276
01:06:08,470 --> 01:06:06,319
and they'll be sitting there floating in

1277
01:06:10,150 --> 01:06:08,480
the water that's also one of the

1278
01:06:11,750 --> 01:06:10,160
actions the crew can take if they

1279
01:06:13,589 --> 01:06:11,760
realize that the parachutes haven't

1280
01:06:15,190 --> 01:06:13,599
attached they have a hard-wired button

1281
01:06:16,950 --> 01:06:15,200
right there on their control panel to

1282
01:06:18,710 --> 01:06:16,960
release those parachutes

1283
01:06:20,950 --> 01:06:18,720
within the first two minutes of

1284
01:06:23,910 --> 01:06:20,960
splashdown the teams will get the go to

1285
01:06:25,990 --> 01:06:23,920
proceed in closer the main recovery ship

1286
01:06:27,270 --> 01:06:26,000
will be about three nautical miles away

1287
01:06:29,430 --> 01:06:27,280
or so

1288
01:06:32,150 --> 01:06:29,440
and it'll deploy two fast boats that'll

1289
01:06:34,230 --> 01:06:32,160
get to the capsule much quicker within

1290
01:06:36,870 --> 01:06:34,240
just those two minutes after getting the

1291
01:06:39,029 --> 01:06:36,880
go the first boat will move in and do a

1292
01:06:41,109 --> 01:06:39,039
sniff check around the dragon capsule

1293
01:06:43,349 --> 01:06:41,119
checking for any vapors of hypergolic

1294
01:06:45,990 --> 01:06:43,359
fuels used to power the draco thrusters

1295
01:06:47,910 --> 01:06:46,000
on board the vehicle once they can

1296
01:06:49,750 --> 01:06:47,920
verify that it's safe to approach they

1297
01:06:52,870 --> 01:06:49,760
can move in as kate was talking about

1298
01:06:55,589 --> 01:06:52,880
someone will climb up on the dragon and

1299
01:06:57,109 --> 01:06:55,599
get it rigged the second fast boat is

1300
01:06:58,870 --> 01:06:57,119
basically a backup for everything that

1301
01:07:00,390 --> 01:06:58,880
the first boat is doing and they're also

1302
01:07:02,549 --> 01:07:00,400
responsible for gathering those

1303
01:07:04,470 --> 01:07:02,559
parachutes up out of the water and then

1304
01:07:06,390 --> 01:07:04,480
it'll take about 30 minutes until the

1305
01:07:08,470 --> 01:07:06,400
main recovery vessel gets there and then

1306
01:07:10,870 --> 01:07:08,480
it's time to lift it up out of the water

1307
01:07:12,870 --> 01:07:10,880
yeah so at that point uh the

1308
01:07:15,829 --> 01:07:12,880
capsule will be set onto the the

1309
01:07:17,430 --> 01:07:15,839
platform of the recovery ship and then

1310
01:07:19,589 --> 01:07:17,440
we'll like i said before our flight

1311
01:07:21,750 --> 01:07:19,599
surgeon will uh do those initial

1312
01:07:23,990 --> 01:07:21,760
checkouts we'll pull bob and doug out

1313
01:07:25,990 --> 01:07:24,000
and then they will go into the medical

1314
01:07:29,190 --> 01:07:26,000
tent so like i said that's all going to

1315
01:07:31,670 --> 01:07:29,200
happen within about 60 minutes is is our

1316
01:07:33,670 --> 01:07:31,680
designated timeline for those operations

1317
01:07:37,670 --> 01:07:33,680
and we're really excited to see all of

1318
01:07:40,390 --> 01:07:37,680
that unfold it has been a very long

1319
01:07:42,390 --> 01:07:40,400
morning night so far

1320
01:07:43,589 --> 01:07:42,400
we've been broadcasting for a few hours

1321
01:07:45,029 --> 01:07:43,599
now and

1322
01:07:46,390 --> 01:07:45,039
i don't know about you but i'm starting

1323
01:07:48,710 --> 01:07:46,400
you know the more that we talk about the

1324
01:07:50,630 --> 01:07:48,720
parachute deployment and just recalling

1325
01:07:52,950 --> 01:07:50,640
what that looked and felt like for the

1326
01:07:55,910 --> 01:07:52,960
demo one broadcast i'm i'm i'm getting

1327
01:07:58,230 --> 01:07:55,920
really rejuvenated and really excited to

1328
01:08:00,549 --> 01:07:58,240
see that with our our space dads on

1329
01:08:02,309 --> 01:08:00,559
board and we should be able to show you

1330
01:08:03,670 --> 01:08:02,319
a lot of the same things you saw for

1331
01:08:05,670 --> 01:08:03,680
demo one again it's a little bit

1332
01:08:07,589 --> 01:08:05,680
different as for demo one we had two

1333
01:08:08,549 --> 01:08:07,599
ships out there in the same recovery

1334
01:08:10,549 --> 01:08:08,559
zone

1335
01:08:12,230 --> 01:08:10,559
so we were able to have some of our

1336
01:08:15,349 --> 01:08:12,240
camera assets things like that on the

1337
01:08:16,950 --> 01:08:15,359
other ship uh now it's all on one um but

1338
01:08:19,189 --> 01:08:16,960
one of the first views we should be able

1339
01:08:21,990 --> 01:08:19,199
to see i will be from a nasa high

1340
01:08:23,749 --> 01:08:22,000
altitude research plane the wb-57 it's

1341
01:08:26,309 --> 01:08:23,759
going to be once again flying in the

1342
01:08:28,309 --> 01:08:26,319
area of splashdown for demo one it was

1343
01:08:30,630 --> 01:08:28,319
able to get us an infrared view of the

1344
01:08:33,030 --> 01:08:30,640
capsule actually during that reentry

1345
01:08:34,709 --> 01:08:33,040
period so when it was still glowing very

1346
01:08:36,709 --> 01:08:34,719
brightly on the infrared as it was still

1347
01:08:38,390 --> 01:08:36,719
generating and dissipating a lot of the

1348
01:08:40,070 --> 01:08:38,400
heat of reentry

1349
01:08:41,749 --> 01:08:40,080
able to see the drogue chute deploys and

1350
01:08:42,789 --> 01:08:41,759
then the main deploys and then we'll

1351
01:08:44,789 --> 01:08:42,799
have some

1352
01:08:46,630 --> 01:08:44,799
cameras actually down on the boat on the

1353
01:08:48,709 --> 01:08:46,640
water hopefully getting us some great

1354
01:08:50,870 --> 01:08:48,719
views of dragon as it descends under

1355
01:08:53,430 --> 01:08:50,880
those parachutes so we are looking

1356
01:08:55,030 --> 01:08:53,440
forward to that again we have about six

1357
01:08:57,110 --> 01:08:55,040
hours or so

1358
01:08:59,510 --> 01:08:57,120
until the actual splashdown we're

1359
01:09:03,349 --> 01:08:59,520
targeting that at 11 48

1360
01:09:06,870 --> 01:09:03,359
a.m pacific and i want to make sure 1848

1361
01:09:09,030 --> 01:09:06,880
gmt yeah so if you're just joining us

1362
01:09:11,749 --> 01:09:09,040
bob and doug have completed their eight

1363
01:09:15,030 --> 01:09:11,759
hour sleep shift they woke up about an

1364
01:09:16,870 --> 01:09:15,040
hour ago an hour and 20 minutes or so

1365
01:09:19,030 --> 01:09:16,880
they had a really nice greeting from

1366
01:09:20,630 --> 01:09:19,040
their sons telling them to wake up wake

1367
01:09:23,430 --> 01:09:20,640
up wake up

1368
01:09:25,030 --> 01:09:23,440
and uh they're now in their post-sleep

1369
01:09:28,149 --> 01:09:25,040
phase where they're having their

1370
01:09:30,309 --> 01:09:28,159
breakfast they received their

1371
01:09:32,630 --> 01:09:30,319
basically their informational update

1372
01:09:35,669 --> 01:09:32,640
from the core here at spacex mission

1373
01:09:39,030 --> 01:09:35,679
control in hawthorne california and so

1374
01:09:40,229 --> 01:09:39,040
far everything is looking great or green

1375
01:09:43,189 --> 01:09:40,239
as we say

1376
01:09:45,349 --> 01:09:43,199
for today's recovery operations

1377
01:09:47,269 --> 01:09:45,359
and so as we continue to monitor the

1378
01:09:49,269 --> 01:09:47,279
operations today we do want to keep

1379
01:09:50,309 --> 01:09:49,279
taking your questions on social media so

1380
01:09:52,309 --> 01:09:50,319
we've got a couple that we're going to

1381
01:09:54,390 --> 01:09:52,319
get through right now remember if you

1382
01:09:57,430 --> 01:09:54,400
want to ask us a question get on twitter

1383
01:09:59,910 --> 01:09:57,440
use the hashtag ask nasa first one comes

1384
01:10:02,470 --> 01:09:59,920
from jeff who wants to know is dragon

1385
01:10:05,430 --> 01:10:02,480
naturally buoyant or would the ship sink

1386
01:10:06,709 --> 01:10:05,440
if they open the capsule in the water

1387
01:10:09,030 --> 01:10:06,719
it would not

1388
01:10:11,110 --> 01:10:09,040
dragon is designed to stay afloat for at

1389
01:10:13,110 --> 01:10:11,120
least 24 hours

1390
01:10:15,350 --> 01:10:13,120
if not beyond that but the requirement

1391
01:10:17,350 --> 01:10:15,360
was just to make sure for 24 hours it

1392
01:10:19,189 --> 01:10:17,360
has a ballast system to make sure it's

1393
01:10:20,550 --> 01:10:19,199
upright in the water following the

1394
01:10:22,310 --> 01:10:20,560
splashdown

1395
01:10:23,990 --> 01:10:22,320
and if the crew had to get out of the

1396
01:10:26,390 --> 01:10:24,000
capsule before they get on the boat they

1397
01:10:29,110 --> 01:10:26,400
have practiced those operations as well

1398
01:10:31,030 --> 01:10:29,120
one of the things that we do so often

1399
01:10:33,110 --> 01:10:31,040
with space flight is practice for when

1400
01:10:33,830 --> 01:10:33,120
things don't go according to plan we do

1401
01:10:36,070 --> 01:10:33,840
it

1402
01:10:37,990 --> 01:10:36,080
through simulations through practices in

1403
01:10:39,510 --> 01:10:38,000
the field through test flights like we

1404
01:10:41,590 --> 01:10:39,520
did last year

1405
01:10:43,270 --> 01:10:41,600
so dragon capable of getting the crew

1406
01:10:44,550 --> 01:10:43,280
out of the water but that's not our

1407
01:10:46,390 --> 01:10:44,560
nominal plan

1408
01:10:48,630 --> 01:10:46,400
the plan is to get them out of the

1409
01:10:50,310 --> 01:10:48,640
capsule once it's already on the ship

1410
01:10:51,910 --> 01:10:50,320
much more stable environment a lot

1411
01:10:52,790 --> 01:10:51,920
easier you're not bobbing around in the

1412
01:10:54,149 --> 01:10:52,800
ocean

1413
01:10:55,990 --> 01:10:54,159
by that point

1414
01:10:58,550 --> 01:10:56,000
yeah absolutely so our next question

1415
01:11:00,310 --> 01:10:58,560
coming to us from tardy grads

1416
01:11:03,510 --> 01:11:00,320
the question is how fast will the

1417
01:11:05,030 --> 01:11:03,520
capsule initially enter our atmosphere

1418
01:11:06,550 --> 01:11:05,040
well the capsule

1419
01:11:09,430 --> 01:11:06,560
whenever it departs the international

1420
01:11:11,189 --> 01:11:09,440
space station initially is going 17

1421
01:11:12,470 --> 01:11:11,199
500 miles per hour

1422
01:11:14,229 --> 01:11:12,480
thereabouts

1423
01:11:16,550 --> 01:11:14,239
whenever it is re-entering our

1424
01:11:19,350 --> 01:11:16,560
atmosphere it will actually be slowing

1425
01:11:21,669 --> 01:11:19,360
down to about 350 miles per hour

1426
01:11:23,030 --> 01:11:21,679
partially due to the atmosphere itself

1427
01:11:24,950 --> 01:11:23,040
that friction building up on the

1428
01:11:27,669 --> 01:11:24,960
exterior of the capsule will bring the

1429
01:11:29,270 --> 01:11:27,679
exterior temperature to about 3500

1430
01:11:31,110 --> 01:11:29,280
degrees fahrenheit so that is an

1431
01:11:33,110 --> 01:11:31,120
indication that that the

1432
01:11:35,110 --> 01:11:33,120
the atmosphere and the oxygen is

1433
01:11:36,709 --> 01:11:35,120
actually impacting the capsule and

1434
01:11:38,310 --> 01:11:36,719
slowing it down

1435
01:11:40,390 --> 01:11:38,320
we also have like we mentioned before

1436
01:11:43,189 --> 01:11:40,400
the parachutes that will also further

1437
01:11:46,310 --> 01:11:43,199
decelerate the vehicle from 350 miles

1438
01:11:48,149 --> 01:11:46,320
per hour to a mere 15 16 miles per hour

1439
01:11:49,350 --> 01:11:48,159
whenever it touches down on the ocean

1440
01:11:51,430 --> 01:11:49,360
floor

1441
01:11:53,270 --> 01:11:51,440
all right our next question comes from

1442
01:11:55,189 --> 01:11:53,280
arash who wanted to know is crew dragon

1443
01:11:57,990 --> 01:11:55,199
endeavor reusable

1444
01:12:00,630 --> 01:11:58,000
it is and in fact it's already got a

1445
01:12:03,189 --> 01:12:00,640
mission signed up in its future it's

1446
01:12:05,030 --> 01:12:03,199
going to be flying the crew 2 crew

1447
01:12:05,910 --> 01:12:05,040
which we're targeting for sometime next

1448
01:12:07,350 --> 01:12:05,920
year

1449
01:12:08,709 --> 01:12:07,360
it'll be another international

1450
01:12:10,310 --> 01:12:08,719
contingent heading up to the

1451
01:12:12,470 --> 01:12:10,320
international space station we'll have

1452
01:12:13,910 --> 01:12:12,480
two nasa astronauts on board shane

1453
01:12:15,590 --> 01:12:13,920
kimbrough who's going to be making

1454
01:12:17,510 --> 01:12:15,600
another long duration stay on board the

1455
01:12:20,350 --> 01:12:17,520
international space station and megan

1456
01:12:22,470 --> 01:12:20,360
macarthur who had previously flown on

1457
01:12:24,790 --> 01:12:22,480
sts-125 where she did all of the

1458
01:12:26,790 --> 01:12:24,800
robotics the last time we repaired the

1459
01:12:28,709 --> 01:12:26,800
hubble space telescope and they're going

1460
01:12:30,790 --> 01:12:28,719
to be joined by two international crew

1461
01:12:33,430 --> 01:12:30,800
members as well

1462
01:12:35,430 --> 01:12:33,440
indeed so our next question comes i'm

1463
01:12:37,510 --> 01:12:35,440
gonna say i can say who they are

1464
01:12:40,070 --> 01:12:37,520
go for it it'll be it'll be european

1465
01:12:42,550 --> 01:12:40,080
space agency astronaut tamafesque and

1466
01:12:44,790 --> 01:12:42,560
japanese astronaut aki hoshide

1467
01:12:46,709 --> 01:12:44,800
so another international crew heading up

1468
01:12:49,270 --> 01:12:46,719
on a dragon our first international crew

1469
01:12:53,350 --> 01:12:49,280
is actually slated to launch no later

1470
01:12:54,229 --> 01:12:53,360
than next or this september september

1471
01:12:55,910 --> 01:12:54,239
yes

1472
01:12:58,870 --> 01:12:55,920
so again we are taking your questions

1473
01:13:01,830 --> 01:12:58,880
through the hashtag asknasa on twitter

1474
01:13:03,830 --> 01:13:01,840
our next question comes to us from suraj

1475
01:13:06,310 --> 01:13:03,840
the question is why is the nose cone

1476
01:13:07,590 --> 01:13:06,320
hatch still open great question also

1477
01:13:09,990 --> 01:13:07,600
very observant

1478
01:13:13,510 --> 01:13:10,000
that nose cone is currently still open

1479
01:13:15,830 --> 01:13:13,520
because underneath it are best the four

1480
01:13:18,070 --> 01:13:15,840
forward bulkhead thrusters

1481
01:13:20,709 --> 01:13:18,080
basically meaning those draco engines

1482
01:13:22,870 --> 01:13:20,719
that sit at the top of the dragon

1483
01:13:25,189 --> 01:13:22,880
capsule we'll be utilizing those to

1484
01:13:27,430 --> 01:13:25,199
perform the deorbit burn

1485
01:13:30,310 --> 01:13:27,440
in order to place dragon on its final

1486
01:13:32,310 --> 01:13:30,320
trajectory back to earth so we can't

1487
01:13:34,470 --> 01:13:32,320
close the nose cone until we're done

1488
01:13:36,390 --> 01:13:34,480
using those draco thrusters

1489
01:13:38,709 --> 01:13:36,400
because we don't want to damage the nose

1490
01:13:40,709 --> 01:13:38,719
cup so we'll wait until that

1491
01:13:43,189 --> 01:13:40,719
excuse me we'll wait until the deorbit

1492
01:13:45,430 --> 01:13:43,199
burn is performed and then we will close

1493
01:13:47,350 --> 01:13:45,440
and lock the nose cone in preparation

1494
01:13:49,189 --> 01:13:47,360
for re-entry

1495
01:13:50,630 --> 01:13:49,199
all right our next question comes from

1496
01:13:52,229 --> 01:13:50,640
that girl and

1497
01:13:53,750 --> 01:13:52,239
already calling for a graphic the next

1498
01:13:55,830 --> 01:13:53,760
time you show the orbit map can you

1499
01:13:59,110 --> 01:13:55,840
explain what and where things are

1500
01:14:01,270 --> 01:13:59,120
especially the lines and the dragon so

1501
01:14:02,390 --> 01:14:01,280
if we can pull up the ground track real

1502
01:14:05,910 --> 01:14:02,400
quick

1503
01:14:08,149 --> 01:14:05,920
what you'll see is pretty much two lines

1504
01:14:09,910 --> 01:14:08,159
and dragon itself

1505
01:14:11,830 --> 01:14:09,920
is on that dot right in the middle of

1506
01:14:13,430 --> 01:14:11,840
your screen so it looks like it just

1507
01:14:15,830 --> 01:14:13,440
passed over grease and is heading

1508
01:14:17,990 --> 01:14:15,840
towards the northeast about to head out

1509
01:14:20,070 --> 01:14:18,000
over eastern europe central russia

1510
01:14:22,709 --> 01:14:20,080
eventually right over central china

1511
01:14:25,030 --> 01:14:22,719
those lines are dragon's current orbit

1512
01:14:27,750 --> 01:14:25,040
so if you chase if you trace the line

1513
01:14:29,910 --> 01:14:27,760
from the right of dragon and continue

1514
01:14:31,590 --> 01:14:29,920
you'll see it eventually meets up on the

1515
01:14:33,830 --> 01:14:31,600
other side of the earth and then it

1516
01:14:36,390 --> 01:14:33,840
stops if you watch the point where it

1517
01:14:38,870 --> 01:14:36,400
stops that'll continue to fill in as

1518
01:14:41,270 --> 01:14:38,880
their orbit continues to go so this is

1519
01:14:42,390 --> 01:14:41,280
essentially showing about two orbits of

1520
01:14:44,630 --> 01:14:42,400
planet earth

1521
01:14:47,510 --> 01:14:44,640
and your question your next question

1522
01:14:49,270 --> 01:14:47,520
might be why is it a wavy line is dragon

1523
01:14:51,830 --> 01:14:49,280
kind of flying all over the place and

1524
01:14:52,709 --> 01:14:51,840
that's because the map is

1525
01:14:53,750 --> 01:14:52,719
spread

1526
01:14:55,750 --> 01:14:53,760
flat

1527
01:14:57,910 --> 01:14:55,760
if you were to actually look at dragon's

1528
01:14:59,750 --> 01:14:57,920
orbit on a globe of earth it would look

1529
01:15:02,310 --> 01:14:59,760
like a straight line but the earth

1530
01:15:04,470 --> 01:15:02,320
continues to revolve underneath dragon

1531
01:15:07,030 --> 01:15:04,480
so every time it completes an orbit of

1532
01:15:09,510 --> 01:15:07,040
the earth it's the the earth is still

1533
01:15:10,470 --> 01:15:09,520
turning so its orbit moves slightly to

1534
01:15:12,390 --> 01:15:10,480
the left

1535
01:15:14,870 --> 01:15:12,400
and it continues to move slightly to the

1536
01:15:16,870 --> 01:15:14,880
left every single time it completes an

1537
01:15:18,709 --> 01:15:16,880
orbit of planet earth this is actually

1538
01:15:20,870 --> 01:15:18,719
how we figure out where we're going to

1539
01:15:23,350 --> 01:15:20,880
be coming home and what orbit we need to

1540
01:15:25,669 --> 01:15:23,360
get dragon into specifically so by the

1541
01:15:28,390 --> 01:15:25,679
time that it's in the right orbit it'll

1542
01:15:30,149 --> 01:15:28,400
line itself up perfectly with pensacola

1543
01:15:33,030 --> 01:15:30,159
which is where we're coming home today

1544
01:15:35,830 --> 01:15:33,040
exactly if i'm not mistaken uh you might

1545
01:15:36,950 --> 01:15:35,840
also notice that the lines are yellow

1546
01:15:38,950 --> 01:15:36,960
and red

1547
01:15:42,229 --> 01:15:38,960
the yellow lines indicate where the

1548
01:15:44,470 --> 01:15:42,239
capsule is exposed to sunlight and the

1549
01:15:45,669 --> 01:15:44,480
red lines would ex would indicate where

1550
01:15:47,750 --> 01:15:45,679
it would be

1551
01:15:49,750 --> 01:15:47,760
not in the sunslighter in eclipse as we

1552
01:15:51,830 --> 01:15:49,760
would refer to it as so really great

1553
01:15:54,229 --> 01:15:51,840
question thanks for asking that one our

1554
01:15:56,229 --> 01:15:54,239
next next question comes from jeff will

1555
01:15:58,790 --> 01:15:56,239
there be any live views from inside the

1556
01:16:01,270 --> 01:15:58,800
capsule before and during re-entry and

1557
01:16:03,110 --> 01:16:01,280
splashdown also another great question

1558
01:16:05,270 --> 01:16:03,120
yes we will be bringing you

1559
01:16:07,590 --> 01:16:05,280
views from the capsule where we can like

1560
01:16:10,149 --> 01:16:07,600
we mentioned before there is an expected

1561
01:16:12,630 --> 01:16:10,159
loss of signal or a blackout period

1562
01:16:14,790 --> 01:16:12,640
where we are unable to communicate or

1563
01:16:16,950 --> 01:16:14,800
receive telemetry or video from the

1564
01:16:19,270 --> 01:16:16,960
capsule uh we expect that to last for

1565
01:16:21,990 --> 01:16:19,280
about six minutes but here and there we

1566
01:16:23,750 --> 01:16:22,000
will be able to bring you uh uh footage

1567
01:16:26,149 --> 01:16:23,760
from the capsule as we're able to

1568
01:16:28,070 --> 01:16:26,159
receive it so excited to see bob and

1569
01:16:29,590 --> 01:16:28,080
doug along for the ride

1570
01:16:31,510 --> 01:16:29,600
all right our next question comes from

1571
01:16:33,750 --> 01:16:31,520
aj nico who wants to know is the hatch

1572
01:16:35,590 --> 01:16:33,760
opening automatic or manual what kind of

1573
01:16:36,950 --> 01:16:35,600
system make sure the hatch opens safely

1574
01:16:39,430 --> 01:16:36,960
and properly

1575
01:16:41,430 --> 01:16:39,440
it is a manual hatch opening

1576
01:16:43,669 --> 01:16:41,440
you can open the hatch on either side of

1577
01:16:45,030 --> 01:16:43,679
the capsule itself

1578
01:16:46,790 --> 01:16:45,040
and it's

1579
01:16:48,470 --> 01:16:46,800
got a number of different locks and

1580
01:16:50,950 --> 01:16:48,480
mechanisms in place to make sure you're

1581
01:16:52,709 --> 01:16:50,960
not accidentally opening up the hatch

1582
01:16:55,189 --> 01:16:52,719
you can kind of think of it

1583
01:16:57,110 --> 01:16:55,199
like the escape doors on an airplane

1584
01:16:58,950 --> 01:16:57,120
where you have to go through several

1585
01:17:01,750 --> 01:16:58,960
steps before you can actually there's

1586
01:17:03,189 --> 01:17:01,760
not just a handle to turn and open it

1587
01:17:05,830 --> 01:17:03,199
you have to go through several steps to

1588
01:17:08,149 --> 01:17:05,840
physically open the hatch and there are

1589
01:17:09,669 --> 01:17:08,159
a number of different configurations in

1590
01:17:11,350 --> 01:17:09,679
the vehicle you can do to make hatch

1591
01:17:12,790 --> 01:17:11,360
opening easier

1592
01:17:14,790 --> 01:17:12,800
like one thing they can do following

1593
01:17:17,590 --> 01:17:14,800
splashdown is actually increase the

1594
01:17:19,590 --> 01:17:17,600
pressure inside of dragon's cabin so

1595
01:17:21,510 --> 01:17:19,600
it's at a higher pressure than what is

1596
01:17:24,470 --> 01:17:21,520
outside of the capsule and that makes

1597
01:17:26,790 --> 01:17:24,480
the crew's job of opening the capsule

1598
01:17:28,470 --> 01:17:26,800
hatch outward much easier

1599
01:17:30,390 --> 01:17:28,480
so it's kind of there's some little

1600
01:17:31,270 --> 01:17:30,400
things that you don't necessarily think

1601
01:17:34,709 --> 01:17:31,280
about

1602
01:17:37,430 --> 01:17:34,719
but it is always a manual process

1603
01:17:39,189 --> 01:17:37,440
next question comes to us from klaus

1604
01:17:41,430 --> 01:17:39,199
question is what is the difference

1605
01:17:45,110 --> 01:17:41,440
between the capsule suits and the ones

1606
01:17:47,590 --> 01:17:45,120
used for eva or extra vehicular activity

1607
01:17:50,070 --> 01:17:47,600
yeah so those eva suits used on the

1608
01:17:52,390 --> 01:17:50,080
international space space station are

1609
01:17:54,229 --> 01:17:52,400
famously used for space walks personally

1610
01:17:56,630 --> 01:17:54,239
one of my favorite things to watch on

1611
01:17:58,630 --> 01:17:56,640
nasa tv or those space walks

1612
01:18:01,669 --> 01:17:58,640
those suits are designed to operate in

1613
01:18:04,310 --> 01:18:01,679
the vacuum of space whereas our sp our

1614
01:18:06,390 --> 01:18:04,320
flight suits for inside crew dragon are

1615
01:18:08,310 --> 01:18:06,400
not so we won't be performing any eva

1616
01:18:10,630 --> 01:18:08,320
suits in these ones however they are

1617
01:18:13,350 --> 01:18:10,640
designed to protect the crew in the

1618
01:18:15,590 --> 01:18:13,360
event of a depressurization event

1619
01:18:17,510 --> 01:18:15,600
the face shields come are able to come

1620
01:18:20,149 --> 01:18:17,520
down and lock and we are able to

1621
01:18:22,790 --> 01:18:20,159
pressurize the suits themselves

1622
01:18:25,430 --> 01:18:22,800
in order to protect the crew in the

1623
01:18:27,350 --> 01:18:25,440
unlikely event of a depressurization

1624
01:18:28,550 --> 01:18:27,360
that being said that's the primary

1625
01:18:30,310 --> 01:18:28,560
difference why

1626
01:18:31,590 --> 01:18:30,320
while they're both white and

1627
01:18:33,270 --> 01:18:31,600
they're both pretty good looking in

1628
01:18:35,750 --> 01:18:33,280
their own ways

1629
01:18:38,070 --> 01:18:35,760
one is much bulkier and that is because

1630
01:18:41,750 --> 01:18:38,080
you know those eva suits are designed to

1631
01:18:44,310 --> 01:18:41,760
essentially do that hard exterior work

1632
01:18:46,229 --> 01:18:44,320
on the iss external in the in the vacuum

1633
01:18:48,550 --> 01:18:46,239
of space yeah they're also kind of

1634
01:18:50,709 --> 01:18:48,560
carrying their atmosphere with them with

1635
01:18:52,790 --> 01:18:50,719
the dragon suit you have an umbilical to

1636
01:18:54,709 --> 01:18:52,800
plug it into the seats

1637
01:18:56,550 --> 01:18:54,719
and we have a great video that we've

1638
01:18:58,310 --> 01:18:56,560
showed a couple of times tonight where a

1639
01:19:01,030 --> 01:18:58,320
spacex suit engineer describes it as

1640
01:19:02,630 --> 01:19:01,040
kind of a suit seat system

1641
01:19:05,189 --> 01:19:02,640
where the suit's able to plug in and

1642
01:19:06,550 --> 01:19:05,199
draw all of that breathing gas and

1643
01:19:09,030 --> 01:19:06,560
cooling air

1644
01:19:10,709 --> 01:19:09,040
whereas those big bulky emu's it's all

1645
01:19:12,870 --> 01:19:10,719
in their backpack where they bring out

1646
01:19:14,470 --> 01:19:12,880
all of their breathing gas their water

1647
01:19:16,070 --> 01:19:14,480
which is not only used for drinking for

1648
01:19:18,310 --> 01:19:16,080
the astronauts but also for keeping them

1649
01:19:19,750 --> 01:19:18,320
cool while they're working outside in

1650
01:19:21,430 --> 01:19:19,760
space

1651
01:19:22,790 --> 01:19:21,440
our next question comes from max who

1652
01:19:26,070 --> 01:19:22,800
wanted to know do they control the

1653
01:19:27,830 --> 01:19:26,080
landing location of the ship in any way

1654
01:19:30,229 --> 01:19:27,840
if so how

1655
01:19:33,270 --> 01:19:30,239
the astronauts themselves are not as

1656
01:19:35,510 --> 01:19:33,280
again dragon is flying autonomously but

1657
01:19:36,709 --> 01:19:35,520
what we're able to do is

1658
01:19:38,630 --> 01:19:36,719
actually

1659
01:19:40,550 --> 01:19:38,640
calculate where dragon

1660
01:19:42,149 --> 01:19:40,560
will have an opportunity to splash down

1661
01:19:44,550 --> 01:19:42,159
and then we're able to give those

1662
01:19:46,470 --> 01:19:44,560
calculations to the flight computer so

1663
01:19:47,750 --> 01:19:46,480
it can then build out what's called a

1664
01:19:49,430 --> 01:19:47,760
burn plan

1665
01:19:51,510 --> 01:19:49,440
you've heard us talk about burns quite a

1666
01:19:53,910 --> 01:19:51,520
bit departure burns and phasing burns

1667
01:19:56,070 --> 01:19:53,920
and the deorbit burn where the vehicle

1668
01:19:58,229 --> 01:19:56,080
will itself calculate when i need to

1669
01:20:00,870 --> 01:19:58,239
fire these engines and how long i need

1670
01:20:03,430 --> 01:20:00,880
to fire them for to line myself up

1671
01:20:05,910 --> 01:20:03,440
exactly where i want to splash down it's

1672
01:20:07,830 --> 01:20:05,920
incredibly complicated

1673
01:20:09,510 --> 01:20:07,840
and only people like kate are able to do

1674
01:20:11,590 --> 01:20:09,520
stuff like that

1675
01:20:14,070 --> 01:20:11,600
but it's

1676
01:20:16,229 --> 01:20:14,080
the the crew is largely out of the loop

1677
01:20:18,070 --> 01:20:16,239
for those it's mostly done

1678
01:20:19,030 --> 01:20:18,080
with a lot of support here down on the

1679
01:20:21,270 --> 01:20:19,040
ground

1680
01:20:24,070 --> 01:20:21,280
and the dragon spacecraft itself exactly

1681
01:20:26,950 --> 01:20:24,080
yeah bob and doug's primary role during

1682
01:20:29,350 --> 01:20:26,960
the reentry phase will simply to be

1683
01:20:31,590 --> 01:20:29,360
monitoring the status and the telemetry

1684
01:20:33,910 --> 01:20:31,600
that is being displayed on their heads

1685
01:20:35,510 --> 01:20:33,920
up display there which i love that view

1686
01:20:37,189 --> 01:20:35,520
that we get inside the capsule where we

1687
01:20:38,470 --> 01:20:37,199
can actually see the screens that

1688
01:20:40,550 --> 01:20:38,480
they're looking at

1689
01:20:42,390 --> 01:20:40,560
i think it's pretty cool those screens

1690
01:20:44,790 --> 01:20:42,400
are touch screen and kind of going back

1691
01:20:47,510 --> 01:20:44,800
to the the question of the suits

1692
01:20:49,350 --> 01:20:47,520
are flight suits for inside crew dragon

1693
01:20:51,830 --> 01:20:49,360
are capable of interacting with that

1694
01:20:53,669 --> 01:20:51,840
touch screen they are capacitive so

1695
01:20:56,070 --> 01:20:53,679
bob and doug are able to

1696
01:20:58,550 --> 01:20:56,080
utilize a really high tech

1697
01:21:00,550 --> 01:20:58,560
and easy to use screen as opposed to if

1698
01:21:01,590 --> 01:21:00,560
you think back to if you've ever seen

1699
01:21:03,750 --> 01:21:01,600
like uh

1700
01:21:05,510 --> 01:21:03,760
the flight deck of

1701
01:21:07,590 --> 01:21:05,520
an airplane or if you think back to the

1702
01:21:09,510 --> 01:21:07,600
flight deck the control plant panels in

1703
01:21:11,430 --> 01:21:09,520
the space shuttle where there were a lot

1704
01:21:13,669 --> 01:21:11,440
of buttons and switches

1705
01:21:15,910 --> 01:21:13,679
now that that screen is flat and we're

1706
01:21:17,910 --> 01:21:15,920
also able to simply

1707
01:21:19,990 --> 01:21:17,920
rotate the the data that we are to be

1708
01:21:21,430 --> 01:21:20,000
that's being displayed uh depending on

1709
01:21:25,430 --> 01:21:21,440
what phase of the mission that we're in

1710
01:21:27,590 --> 01:21:25,440
so it also cuts down on the bulkiness

1711
01:21:30,470 --> 01:21:27,600
yeah the bulkiness of of the display

1712
01:21:33,510 --> 01:21:30,480
itself because we're able to configure

1713
01:21:35,590 --> 01:21:33,520
and specialize um exactly what's being

1714
01:21:36,390 --> 01:21:35,600
shown depending on what's going on

1715
01:21:37,830 --> 01:21:36,400
yeah

1716
01:21:39,430 --> 01:21:37,840
all right we'll get to a couple more

1717
01:21:41,830 --> 01:21:39,440
questions in just a second if you're

1718
01:21:43,750 --> 01:21:41,840
just tuning in though

1719
01:21:46,470 --> 01:21:43,760
uh we're about to bring bob bankin and

1720
01:21:47,910 --> 01:21:46,480
doug hurley home from their stay on

1721
01:21:50,070 --> 01:21:47,920
board the international space station

1722
01:21:52,149 --> 01:21:50,080
they're flying in crew dragon endeavor

1723
01:21:53,669 --> 01:21:52,159
they've woken up on board the spacecraft

1724
01:21:56,390 --> 01:21:53,679
they're just finishing up their post

1725
01:21:57,669 --> 01:21:56,400
sleep and they'll not have a whole lot

1726
01:21:59,669 --> 01:21:57,679
to do over the next couple of hours

1727
01:22:01,350 --> 01:21:59,679
until we really start getting into the

1728
01:22:03,669 --> 01:22:01,360
meat of the operations and that's going

1729
01:22:05,830 --> 01:22:03,679
to start when we get ready to separate

1730
01:22:07,270 --> 01:22:05,840
the trunk from the dragon spacecraft

1731
01:22:09,669 --> 01:22:07,280
yeah and that's coming up in almost five

1732
01:22:11,270 --> 01:22:09,679
hours exactly so yeah

1733
01:22:12,390 --> 01:22:11,280
a little bit of ways to get so we've got

1734
01:22:14,629 --> 01:22:12,400
some time

1735
01:22:16,310 --> 01:22:14,639
uh that cl that trunk separation is

1736
01:22:18,950 --> 01:22:16,320
immediately preceded by something called

1737
01:22:21,270 --> 01:22:18,960
the claw separation and that's just the

1738
01:22:23,590 --> 01:22:21,280
uh the attachment uh fixture between the

1739
01:22:25,350 --> 01:22:23,600
trunk and the capsule itself and just to

1740
01:22:27,110 --> 01:22:25,360
run down some quick times for you again

1741
01:22:30,510 --> 01:22:27,120
real quick we're expecting that cloth

1742
01:22:34,629 --> 01:22:30,520
separation at about 10 51 a.m pacific or

1743
01:22:37,830 --> 01:22:34,639
1751 gmt and then just less than 50

1744
01:22:39,830 --> 01:22:37,840
seconds later at 10 51 and 54 seconds

1745
01:22:41,750 --> 01:22:39,840
the trunk itself will separate from

1746
01:22:43,590 --> 01:22:41,760
dragon and that trunk eventually burns

1747
01:22:45,830 --> 01:22:43,600
up in the earth's atmosphere and then

1748
01:22:47,830 --> 01:22:45,840
after that it's onto the orbiter yeah so

1749
01:22:50,629 --> 01:22:47,840
we'll perform the deorbit burn that'll

1750
01:22:53,590 --> 01:22:50,639
last about 11 and a half minutes that

1751
01:22:55,990 --> 01:22:53,600
burn is what is going to place dragon on

1752
01:22:58,790 --> 01:22:56,000
its final trajectory to the landing zone

1753
01:23:00,070 --> 01:22:58,800
off of the coast of pensacola florida uh

1754
01:23:02,790 --> 01:23:00,080
like we said before they're splashing

1755
01:23:05,510 --> 01:23:02,800
down in the gulf of mexico today uh once

1756
01:23:07,990 --> 01:23:05,520
we perform the deorbit burn we will then

1757
01:23:10,390 --> 01:23:08,000
close and lock the nose cone as we no

1758
01:23:13,270 --> 01:23:10,400
longer need to expose those

1759
01:23:15,030 --> 01:23:13,280
forward dracos that are used in order to

1760
01:23:17,750 --> 01:23:15,040
perform the the

1761
01:23:19,910 --> 01:23:17,760
excuse me in order to perform to perform

1762
01:23:22,790 --> 01:23:19,920
the deorbit burn

1763
01:23:25,110 --> 01:23:22,800
after that we will have a re-entry of

1764
01:23:27,750 --> 01:23:25,120
the capsule back into the earth's

1765
01:23:29,270 --> 01:23:27,760
atmosphere at that point plasma will be

1766
01:23:31,350 --> 01:23:29,280
building up on the exterior of the

1767
01:23:33,910 --> 01:23:31,360
capsule it will be reaching

1768
01:23:35,669 --> 01:23:33,920
an external temperature of about 3500

1769
01:23:38,470 --> 01:23:35,679
degrees bob and doug will stay very

1770
01:23:40,709 --> 01:23:38,480
comfortable with a temperate climate

1771
01:23:43,750 --> 01:23:40,719
inside of the capsule the we have a

1772
01:23:45,590 --> 01:23:43,760
system that flushes cold nitrox air

1773
01:23:48,550 --> 01:23:45,600
both into their suits as well as the

1774
01:23:51,030 --> 01:23:48,560
cabin environment nitrox of course is

1775
01:23:53,350 --> 01:23:51,040
just nitrogen and oxygen it is the air

1776
01:23:54,629 --> 01:23:53,360
that we breathe uh it's also if you've

1777
01:23:56,870 --> 01:23:54,639
ever been scuba diving that's what's in

1778
01:23:58,550 --> 01:23:56,880
your scuba tank so bob and doug will be

1779
01:24:00,390 --> 01:23:58,560
getting a lot of this cold nitrox in

1780
01:24:03,110 --> 01:24:00,400
order to keep them comfortable during

1781
01:24:05,270 --> 01:24:03,120
that reentry phase uh the capsule will

1782
01:24:08,709 --> 01:24:05,280
be slowing down from a

1783
01:24:12,070 --> 01:24:08,719
excuse me from a speed of 17 500 miles

1784
01:24:14,310 --> 01:24:12,080
per hour to about 350 miles per hour

1785
01:24:16,870 --> 01:24:14,320
when we begin to deploy those parachutes

1786
01:24:18,790 --> 01:24:16,880
yeah first out will be the drogue chutes

1787
01:24:20,790 --> 01:24:18,800
there will be two of those and they'll

1788
01:24:22,149 --> 01:24:20,800
do some initial slowing inside the

1789
01:24:24,149 --> 01:24:22,159
earth's atmosphere

1790
01:24:25,430 --> 01:24:24,159
and really stabilization of the dragon

1791
01:24:27,990 --> 01:24:25,440
capsule

1792
01:24:30,390 --> 01:24:28,000
they'll deploy they'll reef just once

1793
01:24:31,830 --> 01:24:30,400
after they come out and will be under

1794
01:24:33,350 --> 01:24:31,840
those drugs for a little bit less than a

1795
01:24:35,750 --> 01:24:33,360
minute and then immediately following

1796
01:24:37,430 --> 01:24:35,760
their detachment the main parachutes

1797
01:24:39,270 --> 01:24:37,440
will deploy and there'll be four much

1798
01:24:41,189 --> 01:24:39,280
larger parachutes that'll reef in two

1799
01:24:43,189 --> 01:24:41,199
different stages and they'll do all of

1800
01:24:45,590 --> 01:24:43,199
the final slowing those drug parachutes

1801
01:24:47,750 --> 01:24:45,600
will come out at about 350 miles an hour

1802
01:24:49,990 --> 01:24:47,760
of vehicle speed when they're about 18

1803
01:24:51,430 --> 01:24:50,000
000 feet in altitude and then by the

1804
01:24:54,229 --> 01:24:51,440
time the mains come out they've already

1805
01:24:56,709 --> 01:24:54,239
slowed down to 119 miles an hour with

1806
01:24:59,189 --> 01:24:56,719
those coming out at about 6 500 feet in

1807
01:25:01,270 --> 01:24:59,199
altitude they'll then be under the main

1808
01:25:06,149 --> 01:25:01,280
parachutes which we expect to deploy at

1809
01:25:07,510 --> 01:25:06,159
about 11 45 a.m pacific time 1845 gmt

1810
01:25:09,110 --> 01:25:07,520
and they'll be under those shoots for a

1811
01:25:12,470 --> 01:25:09,120
little more than three minutes before

1812
01:25:15,350 --> 01:25:12,480
they splash down at 11 48 a.m pacific

1813
01:25:17,830 --> 01:25:15,360
1848 gmt

1814
01:25:19,189 --> 01:25:17,840
yeah they'll be going only 15 16 miles

1815
01:25:21,910 --> 01:25:19,199
per hour when they do make that

1816
01:25:24,310 --> 01:25:21,920
splashdown in the gulf of mexico

1817
01:25:26,550 --> 01:25:24,320
as i've mentioned before this reentry

1818
01:25:28,070 --> 01:25:26,560
phase will get them about four g's

1819
01:25:30,149 --> 01:25:28,080
they'll be experiencing about four g's

1820
01:25:32,390 --> 01:25:30,159
while they're sitting in their seat we

1821
01:25:34,390 --> 01:25:32,400
they also experienced about four g's on

1822
01:25:36,390 --> 01:25:34,400
the ascent phase or during the launch

1823
01:25:38,310 --> 01:25:36,400
phase of the mission so really nothing

1824
01:25:39,990 --> 01:25:38,320
that they haven't already experienced

1825
01:25:41,830 --> 01:25:40,000
also they've gone through both of them

1826
01:25:43,510 --> 01:25:41,840
being test pilots and having flown on

1827
01:25:46,070 --> 01:25:43,520
shuttle missions have gone through

1828
01:25:48,470 --> 01:25:46,080
extensive physical training as well

1829
01:25:51,910 --> 01:25:48,480
so i they're pretty well equipped to

1830
01:25:53,830 --> 01:25:51,920
ride what is basically a pretty moderate

1831
01:25:55,430 --> 01:25:53,840
uh roller coaster

1832
01:25:56,870 --> 01:25:55,440
so yeah they'll be making that splash

1833
01:25:59,030 --> 01:25:56,880
down

1834
01:26:01,830 --> 01:25:59,040
let me just check my

1835
01:26:04,070 --> 01:26:01,840
timing here yeah at 11 48 a.m pacific

1836
01:26:07,189 --> 01:26:04,080
time or 1848

1837
01:26:08,390 --> 01:26:07,199
utc so we are expecting that to all

1838
01:26:10,870 --> 01:26:08,400
happen here

1839
01:26:13,669 --> 01:26:10,880
in less than six hours

1840
01:26:15,990 --> 01:26:13,679
yeah and they are awake they did get an

1841
01:26:17,590 --> 01:26:16,000
initial kind of systems run down from j

1842
01:26:19,830 --> 01:26:17,600
around how he's the core inside of

1843
01:26:22,390 --> 01:26:19,840
mission control hawthorne right behind

1844
01:26:25,110 --> 01:26:22,400
us and as he said we're not tracking any

1845
01:26:26,870 --> 01:26:25,120
issues on dragon dragon's been healthy

1846
01:26:28,870 --> 01:26:26,880
uh from before undock all the way

1847
01:26:30,550 --> 01:26:28,880
through its flight and continues to be

1848
01:26:33,110 --> 01:26:30,560
healthy for that deorbit burn a little

1849
01:26:35,750 --> 01:26:33,120
bit later this morning the only item of

1850
01:26:37,110 --> 01:26:35,760
note that we had was with the recovery

1851
01:26:38,629 --> 01:26:37,120
ship with the generator but we're

1852
01:26:41,270 --> 01:26:38,639
already hearing that that backup

1853
01:26:42,790 --> 01:26:41,280
generator is on dock and being loaded on

1854
01:26:44,629 --> 01:26:42,800
so everything looking good for go

1855
01:26:47,750 --> 01:26:44,639
navigator to make its way out to that

1856
01:26:49,830 --> 01:26:47,760
splashdown zone this morning yeah so all

1857
01:26:51,830 --> 01:26:49,840
really good stuff happening so far and

1858
01:26:54,470 --> 01:26:51,840
we're looking forward to a really

1859
01:26:56,470 --> 01:26:54,480
exciting few hours here coming up again

1860
01:27:00,070 --> 01:26:56,480
we are continuing to take your questions

1861
01:27:01,830 --> 01:27:00,080
through the hashtag asknasa on twitter

1862
01:27:04,470 --> 01:27:01,840
so we'll go to our next question comes

1863
01:27:06,950 --> 01:27:04,480
from christina how long will it take for

1864
01:27:09,910 --> 01:27:06,960
bob and doug to be able to walk normally

1865
01:27:12,229 --> 01:27:09,920
after floating for so long in space

1866
01:27:14,229 --> 01:27:12,239
it it definitely varies from from

1867
01:27:16,550 --> 01:27:14,239
astronaut to astronaut

1868
01:27:19,750 --> 01:27:16,560
every everybody is different and

1869
01:27:21,350 --> 01:27:19,760
everybody tends to react to

1870
01:27:23,669 --> 01:27:21,360
coming home from space a little bit

1871
01:27:25,189 --> 01:27:23,679
different um and you can even have

1872
01:27:27,270 --> 01:27:25,199
differences from

1873
01:27:28,790 --> 01:27:27,280
if you flew a short duration shuttle

1874
01:27:31,030 --> 01:27:28,800
mission and then you fly a longer

1875
01:27:32,790 --> 01:27:31,040
duration your body could react

1876
01:27:35,510 --> 01:27:32,800
differently and it can be pretty

1877
01:27:37,189 --> 01:27:35,520
difficult to walk once you get on

1878
01:27:39,270 --> 01:27:37,199
back into a gravity environment your

1879
01:27:41,350 --> 01:27:39,280
vestibular system which controls your

1880
01:27:43,990 --> 01:27:41,360
balance and your range of motion and

1881
01:27:46,470 --> 01:27:44,000
everything like that can really take a

1882
01:27:47,990 --> 01:27:46,480
hit when you're going from a zero or

1883
01:27:49,990 --> 01:27:48,000
microgravity environment back to a

1884
01:27:52,550 --> 01:27:50,000
gravity so some crew members able to

1885
01:27:54,470 --> 01:27:52,560
walk immediately out of the capsule some

1886
01:27:56,790 --> 01:27:54,480
takes a couple hours until they really

1887
01:28:00,470 --> 01:27:56,800
get their feet steady beneath them

1888
01:28:02,390 --> 01:28:00,480
so it really does vary but again we're

1889
01:28:04,390 --> 01:28:02,400
extremely safety conscious when it comes

1890
01:28:05,750 --> 01:28:04,400
to bringing these crew members home so

1891
01:28:08,390 --> 01:28:05,760
we always make sure we have plenty of

1892
01:28:10,310 --> 01:28:08,400
personnel trained medical officials

1893
01:28:12,310 --> 01:28:10,320
there with them just to

1894
01:28:16,149 --> 01:28:12,320
make sure they're safe

1895
01:28:18,310 --> 01:28:16,159
with their return from space absolutely

1896
01:28:19,830 --> 01:28:18,320
uh something else to note the astronauts

1897
01:28:22,629 --> 01:28:19,840
while on board the international space

1898
01:28:25,590 --> 01:28:22,639
station in addition to doing space walks

1899
01:28:27,669 --> 01:28:25,600
and lots and lots of science experiments

1900
01:28:29,910 --> 01:28:27,679
and eating and sleeping they also do a

1901
01:28:31,830 --> 01:28:29,920
significant amount of exercise in order

1902
01:28:33,430 --> 01:28:31,840
to keep their bodies in tip-top shape

1903
01:28:35,350 --> 01:28:33,440
while they are experiencing a

1904
01:28:37,270 --> 01:28:35,360
microgravity environment

1905
01:28:38,790 --> 01:28:37,280
as dan just said it

1906
01:28:41,110 --> 01:28:38,800
everybody is affected differently but

1907
01:28:43,830 --> 01:28:41,120
one thing is for sure lots of exercise

1908
01:28:47,270 --> 01:28:43,840
while in space ha is able to counteract

1909
01:28:48,229 --> 01:28:47,280
those effects so even though uh it might

1910
01:28:50,149 --> 01:28:48,239
seem like they're going to the

1911
01:28:52,870 --> 01:28:50,159
international space station and having a

1912
01:28:54,870 --> 01:28:52,880
leisurely time hanging out in the cupola

1913
01:28:56,629 --> 01:28:54,880
and taking pictures of planet earth

1914
01:28:59,510 --> 01:28:56,639
rotating below they actually have

1915
01:29:01,430 --> 01:28:59,520
action-packed schedules and exercises as

1916
01:29:03,189 --> 01:29:01,440
a really big piece of that

1917
01:29:04,229 --> 01:29:03,199
going to our next question coming from

1918
01:29:06,950 --> 01:29:04,239
twitter

1919
01:29:08,870 --> 01:29:06,960
uh comes to us from ridge runner

1920
01:29:12,390 --> 01:29:08,880
has the tropical storm influenced the

1921
01:29:14,629 --> 01:29:12,400
landing site yes absolutely so tropical

1922
01:29:16,629 --> 01:29:14,639
storm or hurricane isaiah it was

1923
01:29:19,750 --> 01:29:16,639
recently downgraded back to a tropical

1924
01:29:21,910 --> 01:29:19,760
storm but it has definitely impacted our

1925
01:29:24,470 --> 01:29:21,920
choices for landing site

1926
01:29:26,950 --> 01:29:24,480
we are dragon capsule is capable of

1927
01:29:29,030 --> 01:29:26,960
landing on either the west coast or the

1928
01:29:32,470 --> 01:29:29,040
east coast of florida we have two

1929
01:29:35,830 --> 01:29:32,480
identical recovery ships on either coast

1930
01:29:38,070 --> 01:29:35,840
that is ready and able to support the

1931
01:29:40,950 --> 01:29:38,080
decision on where to land actually isn't

1932
01:29:44,229 --> 01:29:40,960
made until just a few excuse me a few

1933
01:29:45,990 --> 01:29:44,239
hours prior to departure from the iss so

1934
01:29:48,550 --> 01:29:46,000
it's important that both

1935
01:29:49,910 --> 01:29:48,560
coasts have the ability to be able to

1936
01:29:50,830 --> 01:29:49,920
support

1937
01:29:54,310 --> 01:29:50,840
but

1938
01:29:56,709 --> 01:29:54,320
the the opportunity that we had for this

1939
01:29:58,790 --> 01:29:56,719
particular mission we had seven

1940
01:30:01,110 --> 01:29:58,800
potential landing zones picked out and

1941
01:30:03,669 --> 01:30:01,120
due to that tropical storm it ruled out

1942
01:30:06,149 --> 01:30:03,679
all three located on the eastern coast

1943
01:30:07,590 --> 01:30:06,159
of florida so that made decision making

1944
01:30:10,790 --> 01:30:07,600
pretty clear that we were going to

1945
01:30:13,510 --> 01:30:10,800
select from our gulf coast sites and

1946
01:30:16,470 --> 01:30:13,520
after a couple days of evaluation not

1947
01:30:19,430 --> 01:30:16,480
only of wind speeds but also thunder and

1948
01:30:21,510 --> 01:30:19,440
lightning storms in addition to wave

1949
01:30:23,270 --> 01:30:21,520
slope degrees uh

1950
01:30:25,189 --> 01:30:23,280
whenever you land in the ocean

1951
01:30:27,830 --> 01:30:25,199
you're subjected to of course the wind

1952
01:30:30,149 --> 01:30:27,840
as well as the the condition of the seas

1953
01:30:31,830 --> 01:30:30,159
itself all those things taken into

1954
01:30:34,149 --> 01:30:31,840
consideration to make sure that landing

1955
01:30:36,310 --> 01:30:34,159
is safe and as comfortable as possible

1956
01:30:38,629 --> 01:30:36,320
for bob and doug so yeah i would say

1957
01:30:40,870 --> 01:30:38,639
that that tropical storm certainly had a

1958
01:30:42,470 --> 01:30:40,880
major impact but fortunately

1959
01:30:44,229 --> 01:30:42,480
today's conditions anticipated

1960
01:30:47,430 --> 01:30:44,239
conditions for splashdown are going to

1961
01:30:50,870 --> 01:30:47,440
be very mild if not picture perfect with

1962
01:30:53,750 --> 01:30:50,880
a very low degree slope of those waves

1963
01:30:54,870 --> 01:30:53,760
and just barely one mile per hour wind

1964
01:30:57,110 --> 01:30:54,880
yeah we

1965
01:30:58,790 --> 01:30:57,120
we got extremely lucky we've had to kind

1966
01:31:00,550 --> 01:30:58,800
of dodge around weather a bunch with

1967
01:31:02,629 --> 01:31:00,560
this mission for those that remember the

1968
01:31:04,390 --> 01:31:02,639
launch we got all the way down to just

1969
01:31:06,550 --> 01:31:04,400
kind of the final minutes before launch

1970
01:31:09,510 --> 01:31:06,560
and had to scrub just because of some

1971
01:31:12,149 --> 01:31:09,520
storms in the area and things were

1972
01:31:14,390 --> 01:31:12,159
not looking great earlier this week

1973
01:31:15,830 --> 01:31:14,400
and then we just kind of hit that lucky

1974
01:31:17,590 --> 01:31:15,840
window that's why the teams will

1975
01:31:20,470 --> 01:31:17,600
continue to go down all the way to just

1976
01:31:22,629 --> 01:31:20,480
the final hours before we undock to try

1977
01:31:24,629 --> 01:31:22,639
and preserve these opportunities because

1978
01:31:26,790 --> 01:31:24,639
weather around florida very dynamic you

1979
01:31:28,709 --> 01:31:26,800
just really never know

1980
01:31:30,790 --> 01:31:28,719
our next question comes from jasmine who

1981
01:31:34,229 --> 01:31:30,800
wants to know which is more stressful

1982
01:31:36,310 --> 01:31:34,239
launch day or splashdown day

1983
01:31:38,149 --> 01:31:36,320
it's kind of a personal question i don't

1984
01:31:40,950 --> 01:31:38,159
really know which one i'm usually more

1985
01:31:45,030 --> 01:31:43,270
i think splashdown day kind of feels

1986
01:31:48,550 --> 01:31:45,040
like it lasts longer launches something

1987
01:31:50,310 --> 01:31:48,560
that's over so quick uh you either

1988
01:31:52,229 --> 01:31:50,320
you did it or you didn't exactly um

1989
01:31:53,750 --> 01:31:52,239
splashdown day we we have a little bit

1990
01:31:56,550 --> 01:31:53,760
more time things take a little bit

1991
01:32:00,950 --> 01:31:58,070
i don't i don't have a good answer for

1992
01:32:03,110 --> 01:32:00,960
it yeah it's something i noticed in the

1993
01:32:04,870 --> 01:32:03,120
interviews that bob and doug have been

1994
01:32:06,950 --> 01:32:04,880
performing on station for the last

1995
01:32:08,470 --> 01:32:06,960
couple of weeks uh they're not stressed

1996
01:32:10,470 --> 01:32:08,480
about anything

1997
01:32:12,390 --> 01:32:10,480
you know they're they're cool cats up

1998
01:32:13,669 --> 01:32:12,400
there uh you know and that's partially

1999
01:32:15,910 --> 01:32:13,679
attributed to not only their

2000
01:32:17,910 --> 01:32:15,920
personalities but also the fact that

2001
01:32:20,470 --> 01:32:17,920
they have done extensive training with

2002
01:32:23,270 --> 01:32:20,480
the nasa and spacex teams in preparation

2003
01:32:25,110 --> 01:32:23,280
for every element of this mission

2004
01:32:27,669 --> 01:32:25,120
everything from

2005
01:32:30,709 --> 01:32:27,679
the the phases that you go through prior

2006
01:32:32,870 --> 01:32:30,719
to launch to launch itself to ascent

2007
01:32:34,950 --> 01:32:32,880
docking all of the mission operations

2008
01:32:36,470 --> 01:32:34,960
while actually on station and completing

2009
01:32:38,550 --> 01:32:36,480
the mission objectives for this

2010
01:32:41,189 --> 01:32:38,560
demonstration mission and then of course

2011
01:32:42,950 --> 01:32:41,199
undocking and reentry

2012
01:32:44,629 --> 01:32:42,960
uh they've they've done it all they're

2013
01:32:45,990 --> 01:32:44,639
they're not it doesn't i never got the

2014
01:32:48,229 --> 01:32:46,000
impression that they were stressed about

2015
01:32:51,669 --> 01:32:48,239
anything my personal response would be i

2016
01:32:53,590 --> 01:32:51,679
think it's similar splashdown is has a

2017
01:32:56,950 --> 01:32:53,600
little bit more dynamic in terms of to

2018
01:32:59,189 --> 01:32:56,960
the total timeline uh also it's just you

2019
01:33:00,709 --> 01:32:59,199
know it's just so exciting that knowing

2020
01:33:02,390 --> 01:33:00,719
that we're bringing our space dads home

2021
01:33:04,149 --> 01:33:02,400
today

2022
01:33:05,430 --> 01:33:04,159
all right our next question comes from

2023
01:33:07,430 --> 01:33:05,440
megan who wants to know what the

2024
01:33:09,669 --> 01:33:07,440
difference is between zero gravity and

2025
01:33:11,270 --> 01:33:09,679
microgravity it's it's a good thing to

2026
01:33:13,350 --> 01:33:11,280
pick up on because it's something that

2027
01:33:15,430 --> 01:33:13,360
gets kind of confused between the two

2028
01:33:17,350 --> 01:33:15,440
very easily for sure on board the

2029
01:33:18,550 --> 01:33:17,360
international space station and

2030
01:33:21,350 --> 01:33:18,560
bob and doug right now what they're

2031
01:33:23,110 --> 01:33:21,360
experiencing is microgravity

2032
01:33:25,430 --> 01:33:23,120
so they are actually subject to the

2033
01:33:27,270 --> 01:33:25,440
earth's gravity right now almost the

2034
01:33:28,470 --> 01:33:27,280
exact amount that we are when you're on

2035
01:33:30,229 --> 01:33:28,480
the international space station you're

2036
01:33:33,430 --> 01:33:30,239
subject to more than 90 percent of the

2037
01:33:34,790 --> 01:33:33,440
earth's gravity the reason it seems like

2038
01:33:37,030 --> 01:33:34,800
everything floats for them is because

2039
01:33:38,950 --> 01:33:37,040
they are in microgravity and that's

2040
01:33:41,350 --> 01:33:38,960
because they're in a constant state of

2041
01:33:44,229 --> 01:33:41,360
free fall you can actually mimic

2042
01:33:45,910 --> 01:33:44,239
the exact environment that they have

2043
01:33:47,910 --> 01:33:45,920
just on an airplane

2044
01:33:50,390 --> 01:33:47,920
if you fly in a parabola that has an

2045
01:33:52,790 --> 01:33:50,400
exact deceleration rate as the rate of

2046
01:33:54,229 --> 01:33:52,800
gravity going down and

2047
01:33:55,830 --> 01:33:54,239
one of the easiest ways to kind of

2048
01:33:58,149 --> 01:33:55,840
visualize it is

2049
01:34:00,310 --> 01:33:58,159
if you were to stand on a hill and throw

2050
01:34:02,310 --> 01:34:00,320
a ball as hard as you could that ball

2051
01:34:03,990 --> 01:34:02,320
would eventually go out and then it

2052
01:34:05,750 --> 01:34:04,000
would come back down to earth and the

2053
01:34:07,750 --> 01:34:05,760
harder you threw that ball the further

2054
01:34:09,510 --> 01:34:07,760
it would go now if you could throw that

2055
01:34:11,750 --> 01:34:09,520
ball so fast

2056
01:34:13,270 --> 01:34:11,760
that it was able to just keep going and

2057
01:34:14,870 --> 01:34:13,280
going and going

2058
01:34:16,950 --> 01:34:14,880
that's essentially what they're doing

2059
01:34:18,709 --> 01:34:16,960
they're moving at a speed so fast that

2060
01:34:20,390 --> 01:34:18,719
even though they're falling

2061
01:34:22,070 --> 01:34:20,400
they're moving forward too fast to ever

2062
01:34:24,149 --> 01:34:22,080
hit the ground so you're in a constant

2063
01:34:26,870 --> 01:34:24,159
state of free fall and that's why they

2064
01:34:29,350 --> 01:34:26,880
experience microgravity zero gravity

2065
01:34:31,510 --> 01:34:29,360
would be the actual absence of gravity

2066
01:34:33,510 --> 01:34:31,520
so you would have to be much further

2067
01:34:36,390 --> 01:34:33,520
away from something

2068
01:34:38,550 --> 01:34:36,400
like planet earth which has a very big

2069
01:34:39,669 --> 01:34:38,560
gravitational pull as it is a very large

2070
01:34:41,270 --> 01:34:39,679
object

2071
01:34:42,950 --> 01:34:41,280
yeah great question

2072
01:34:45,189 --> 01:34:42,960
good ears picking up on on the

2073
01:34:47,669 --> 01:34:45,199
difference there next question comes

2074
01:34:49,669 --> 01:34:47,679
from jason will the plasma trail be

2075
01:34:51,430 --> 01:34:49,679
visible in daylight oh that's a great

2076
01:34:53,189 --> 01:34:51,440
question so what jason is referring to

2077
01:34:54,870 --> 01:34:53,199
there is the plasma that will be

2078
01:34:57,270 --> 01:34:54,880
building up on the exterior of the

2079
01:34:58,550 --> 01:34:57,280
capsule as it is re-entering earth's

2080
01:34:59,910 --> 01:34:58,560
atmosphere

2081
01:35:02,229 --> 01:34:59,920
i'm actually not sure if it will be

2082
01:35:04,870 --> 01:35:02,239
visible to the naked eye because it it

2083
01:35:07,430 --> 01:35:04,880
will be some distance away from the the

2084
01:35:09,750 --> 01:35:07,440
coast of florida so i'm not sure if

2085
01:35:11,990 --> 01:35:09,760
folks on land will be able to see it

2086
01:35:13,590 --> 01:35:12,000
that being said we will certainly have

2087
01:35:15,990 --> 01:35:13,600
will be able to provide visual of that

2088
01:35:19,350 --> 01:35:16,000
we will have a thermal camera

2089
01:35:20,870 --> 01:35:19,360
mounted on our wb 57 plane which will be

2090
01:35:22,790 --> 01:35:20,880
bringing us live views as it is

2091
01:35:25,430 --> 01:35:22,800
re-entering so we will certainly be

2092
01:35:26,950 --> 01:35:25,440
seeing that plasma tail for sure

2093
01:35:29,590 --> 01:35:26,960
but in terms of being able to see it

2094
01:35:31,109 --> 01:35:29,600
with the naked eye i i don't believe so

2095
01:35:33,990 --> 01:35:31,119
because like mentioned it will be

2096
01:35:35,510 --> 01:35:34,000
occurring in the daylight

2097
01:35:37,430 --> 01:35:35,520
all right so we're going to continue

2098
01:35:40,629 --> 01:35:37,440
taking those questions throughout again

2099
01:35:42,870 --> 01:35:40,639
just keep using the hashtag ask nasa if

2100
01:35:44,790 --> 01:35:42,880
you're just now tuning in things haven't

2101
01:35:47,750 --> 01:35:44,800
quite picked up yet but bob and doug are

2102
01:35:49,030 --> 01:35:47,760
awake on board dragon ship endeavor

2103
01:35:50,870 --> 01:35:49,040
and awaiting

2104
01:35:53,109 --> 01:35:50,880
really just all of the activities that

2105
01:35:54,950 --> 01:35:53,119
are coming up in a couple of hours and

2106
01:35:57,189 --> 01:35:54,960
we'll run down a couple of key times for

2107
01:35:58,950 --> 01:35:57,199
you just to know when it's really time

2108
01:35:59,750 --> 01:35:58,960
to pay attention when things are heating

2109
01:36:01,030 --> 01:35:59,760
up

2110
01:36:03,669 --> 01:36:01,040
so we're going to start off the

2111
01:36:06,070 --> 01:36:03,679
operations a little bit later today with

2112
01:36:07,910 --> 01:36:06,080
our trunk separation and this is when

2113
01:36:09,189 --> 01:36:07,920
we'll essentially split dragon into two

2114
01:36:11,590 --> 01:36:09,199
different pieces

2115
01:36:13,510 --> 01:36:11,600
the trunk will detach from the capsule

2116
01:36:15,590 --> 01:36:13,520
the trunk burns up in the earth's

2117
01:36:18,470 --> 01:36:15,600
atmosphere exposing the capsule's heat

2118
01:36:20,070 --> 01:36:18,480
shield for its eventual reentry before

2119
01:36:22,550 --> 01:36:20,080
the trunk can separate we need to get

2120
01:36:24,790 --> 01:36:22,560
dragon in the appropriate attitude and

2121
01:36:27,350 --> 01:36:24,800
do something called a slew which is just

2122
01:36:29,590 --> 01:36:27,360
a maneuver to correctly orient dragon

2123
01:36:32,149 --> 01:36:29,600
for that trunk separation that's

2124
01:36:35,350 --> 01:36:32,159
scheduled to take place at 10 48 a.m

2125
01:36:38,310 --> 01:36:35,360
pacific 1748 gmt

2126
01:36:40,470 --> 01:36:38,320
just a little under five hours from now

2127
01:36:42,790 --> 01:36:40,480
and then the claw will separate

2128
01:36:45,109 --> 01:36:42,800
this is what actually connects the trunk

2129
01:36:47,189 --> 01:36:45,119
and through a number of fluid and other

2130
01:36:49,669 --> 01:36:47,199
quick disconnects to the dragon capsule

2131
01:36:51,990 --> 01:36:49,679
itself that claw will separate followed

2132
01:36:53,590 --> 01:36:52,000
shortly after by the trunk itself and

2133
01:36:58,470 --> 01:36:53,600
we're looking for that trunk separation

2134
01:37:00,790 --> 01:36:58,480
at 10 51 a.m pacific 1751 gmt yeah so

2135
01:37:04,149 --> 01:37:00,800
after we get that separation we will

2136
01:37:06,390 --> 01:37:04,159
then position the vehicle into the

2137
01:37:07,990 --> 01:37:06,400
appropriate attitude to begin that

2138
01:37:12,310 --> 01:37:08,000
deorbit burn

2139
01:37:14,229 --> 01:37:12,320
about 11 and a half minutes and that

2140
01:37:16,229 --> 01:37:14,239
deorbit burn is what will be placing

2141
01:37:17,910 --> 01:37:16,239
dragon on its final trajectory really

2142
01:37:19,830 --> 01:37:17,920
pointing it home

2143
01:37:22,709 --> 01:37:19,840
to its landing spot off the coast of

2144
01:37:24,870 --> 01:37:22,719
florida in the gulf of mexico so once

2145
01:37:26,629 --> 01:37:24,880
that deorbit burn is completed we will

2146
01:37:29,510 --> 01:37:26,639
then note that that's not actually the

2147
01:37:31,270 --> 01:37:29,520
reentry reentry phase that's just the

2148
01:37:34,310 --> 01:37:31,280
trajectory positioning

2149
01:37:35,990 --> 01:37:34,320
the nose cone will be closing at 11 11

2150
01:37:38,149 --> 01:37:36,000
a.m the

2151
01:37:40,870 --> 01:37:38,159
forward bulkhead thrusters the forward

2152
01:37:43,510 --> 01:37:40,880
dracos are what will be used to perform

2153
01:37:45,669 --> 01:37:43,520
that previous deorbit burn so once those

2154
01:37:48,629 --> 01:37:45,679
are no longer needed they'll be safe and

2155
01:37:51,350 --> 01:37:48,639
will lock the nose cone and make sure

2156
01:37:54,070 --> 01:37:51,360
that that forward hatch located there

2157
01:37:55,910 --> 01:37:54,080
is well protected for the re-entry the

2158
01:37:59,270 --> 01:37:55,920
capsule will then begin to re-enter

2159
01:38:01,750 --> 01:37:59,280
earth's atmosphere and at 11 36 a.m

2160
01:38:04,390 --> 01:38:01,760
pacific or 1836

2161
01:38:07,030 --> 01:38:04,400
1836 universal

2162
01:38:08,070 --> 01:38:07,040
we will have an expected communications

2163
01:38:09,510 --> 01:38:08,080
blackout

2164
01:38:10,950 --> 01:38:09,520
like i said there will be plasma

2165
01:38:12,709 --> 01:38:10,960
building up on the exterior of the

2166
01:38:14,350 --> 01:38:12,719
vehicle as it will be reaching

2167
01:38:16,950 --> 01:38:14,360
temperatures towards

2168
01:38:18,390 --> 01:38:16,960
3500 degrees fahrenheit

2169
01:38:20,709 --> 01:38:18,400
so we will have a communications

2170
01:38:22,950 --> 01:38:20,719
blackout period or loss of signal and

2171
01:38:24,550 --> 01:38:22,960
that will last about six minutes during

2172
01:38:26,390 --> 01:38:24,560
that time we won't be able to command

2173
01:38:28,550 --> 01:38:26,400
the vehicle or

2174
01:38:29,990 --> 01:38:28,560
or receive telemetry that being said

2175
01:38:33,109 --> 01:38:30,000
dragon is designed to be fully

2176
01:38:36,070 --> 01:38:33,119
autonomous so it's driving itself anyway

2177
01:38:37,830 --> 01:38:36,080
uh at 11 36 a.m in the middle of that

2178
01:38:40,390 --> 01:38:37,840
communications blackout we will have

2179
01:38:42,390 --> 01:38:40,400
entry interface this is when the capsule

2180
01:38:44,149 --> 01:38:42,400
is essentially beginning to feel the

2181
01:38:45,350 --> 01:38:44,159
aerodynamic forces of the earth's

2182
01:38:47,030 --> 01:38:45,360
atmosphere

2183
01:38:51,109 --> 01:38:47,040
we'll get those communications back at

2184
01:38:52,390 --> 01:38:51,119
11 42 a.m pacific or 1842

2185
01:38:54,229 --> 01:38:52,400
universal

2186
01:38:56,310 --> 01:38:54,239
we'll get those communications back and

2187
01:38:58,149 --> 01:38:56,320
we'll do a comms check with bob and doug

2188
01:39:01,510 --> 01:38:58,159
make sure that they're doing good and

2189
01:39:03,830 --> 01:39:01,520
feeling okay and then at 11 44 a.m

2190
01:39:06,070 --> 01:39:03,840
pacific we will begin the parachute

2191
01:39:07,990 --> 01:39:06,080
deployment so we'll deploy the drogue

2192
01:39:10,390 --> 01:39:08,000
parachutes those three parachutes that

2193
01:39:12,629 --> 01:39:10,400
are designed to initially slow begin

2194
01:39:13,910 --> 01:39:12,639
continue to slow the vehicle down uh

2195
01:39:18,149 --> 01:39:13,920
they will

2196
01:39:20,390 --> 01:39:18,159
that we are prepared for the main

2197
01:39:24,070 --> 01:39:20,400
parachute deploy those main shoots will

2198
01:39:26,629 --> 01:39:24,080
come out at 11 45 a.m pacific on the dot

2199
01:39:28,229 --> 01:39:26,639
or 1845 universal

2200
01:39:31,750 --> 01:39:28,239
those main parachutes will further

2201
01:39:35,669 --> 01:39:31,760
decelerate the the vehicle uh down to

2202
01:39:37,430 --> 01:39:35,679
about 15 or 16 miles per hour and uh for

2203
01:39:39,750 --> 01:39:37,440
at that point we'll have splashdown and

2204
01:39:43,270 --> 01:39:39,760
we'll be looking to confirm that at 11

2205
01:39:45,510 --> 01:39:43,280
48 a.m pacific so once splashdown occurs

2206
01:39:47,990 --> 01:39:45,520
the recovery team will move into place

2207
01:39:50,310 --> 01:39:48,000
and uh you know really have the moment

2208
01:39:52,629 --> 01:39:50,320
where we get to pull our space dads uh

2209
01:39:55,189 --> 01:39:52,639
and welcome them back to earth yeah it's

2210
01:39:57,430 --> 01:39:55,199
only expected to take about an hour from

2211
01:39:59,830 --> 01:39:57,440
the moment of splash down until we have

2212
01:40:01,430 --> 01:39:59,840
them out of the capsule on the boat a

2213
01:40:03,750 --> 01:40:01,440
number of things have to happen before

2214
01:40:05,910 --> 01:40:03,760
that takes place uh within about the

2215
01:40:07,830 --> 01:40:05,920
first minute and a half to two minutes

2216
01:40:09,350 --> 01:40:07,840
on mission control hawthorne so the

2217
01:40:10,950 --> 01:40:09,360
flight controllers right behind us will

2218
01:40:11,910 --> 01:40:10,960
give the recovery teams that go to

2219
01:40:13,750 --> 01:40:11,920
proceed

2220
01:40:15,830 --> 01:40:13,760
as they're still getting telemetry or

2221
01:40:18,229 --> 01:40:15,840
data from the spacecraft even after it

2222
01:40:19,910 --> 01:40:18,239
splashes down they're able to make sure

2223
01:40:22,229 --> 01:40:19,920
that we don't have any fuel leaks or

2224
01:40:24,070 --> 01:40:22,239
anything like that and just make sure

2225
01:40:25,510 --> 01:40:24,080
things are as safe as possible before

2226
01:40:27,109 --> 01:40:25,520
additional personnel approach the

2227
01:40:29,270 --> 01:40:27,119
capsule

2228
01:40:31,270 --> 01:40:29,280
there will be two boats that go in two

2229
01:40:33,270 --> 01:40:31,280
fast approach boats the first one will

2230
01:40:35,270 --> 01:40:33,280
get there and do a sniff around the

2231
01:40:36,790 --> 01:40:35,280
capsule for what's called hypergals

2232
01:40:38,149 --> 01:40:36,800
hypergolic fuel

2233
01:40:40,310 --> 01:40:38,159
that's used to

2234
01:40:44,229 --> 01:40:40,320
power the draco thrusters around the

2235
01:40:48,390 --> 01:40:46,550
after they're done with that sniffing

2236
01:40:50,149 --> 01:40:48,400
the second boat will be able to move in

2237
01:40:52,229 --> 01:40:50,159
it acts as a redundant boat for that

2238
01:40:54,149 --> 01:40:52,239
first fast approach boat and is also

2239
01:40:55,669 --> 01:40:54,159
responsible for getting the parachutes

2240
01:40:57,430 --> 01:40:55,679
out of the water

2241
01:40:59,350 --> 01:40:57,440
following all of that work they'll give

2242
01:41:01,270 --> 01:40:59,360
the go for the main recovery vessel to

2243
01:41:03,030 --> 01:41:01,280
move in it'll be waiting just about

2244
01:41:05,030 --> 01:41:03,040
three nautical miles away from the

2245
01:41:06,629 --> 01:41:05,040
splashdown point it'll take about 30

2246
01:41:08,550 --> 01:41:06,639
minutes for it to

2247
01:41:10,550 --> 01:41:08,560
arrive at the capsule

2248
01:41:11,990 --> 01:41:10,560
then it'll be time for the hoisting

2249
01:41:14,470 --> 01:41:12,000
maneuvers so

2250
01:41:16,390 --> 01:41:14,480
while the boat is approaching a spacex

2251
01:41:18,390 --> 01:41:16,400
professional will climb on top of dragon

2252
01:41:20,550 --> 01:41:18,400
and fix some rigging structure

2253
01:41:22,709 --> 01:41:20,560
to the very top of the capsule which was

2254
01:41:24,709 --> 01:41:22,719
going to be grappled by a crane a

2255
01:41:26,950 --> 01:41:24,719
hydraulic crane on the very back of the

2256
01:41:28,709 --> 01:41:26,960
recovery ship go navigator to lift

2257
01:41:30,790 --> 01:41:28,719
dragon out of the water and put it in

2258
01:41:32,790 --> 01:41:30,800
the nest and then it's time to move the

2259
01:41:34,870 --> 01:41:32,800
nest underneath the helipad and get the

2260
01:41:35,910 --> 01:41:34,880
crew out yeah so a number of individuals

2261
01:41:38,550 --> 01:41:35,920
will be

2262
01:41:39,350 --> 01:41:38,560
helping to position the dragon capsule

2263
01:41:42,390 --> 01:41:39,360
and

2264
01:41:44,550 --> 01:41:42,400
we'll open the side hatch our flight

2265
01:41:46,149 --> 01:41:44,560
surgeon will check in with bob and doug

2266
01:41:47,510 --> 01:41:46,159
before they even unstrap or anything

2267
01:41:48,470 --> 01:41:47,520
like that make sure they're feeling all

2268
01:41:50,229 --> 01:41:48,480
right

2269
01:41:52,709 --> 01:41:50,239
and then we will have bob and doug

2270
01:41:55,030 --> 01:41:52,719
egress from the capsule

2271
01:41:57,669 --> 01:41:55,040
and then we will cut them into the

2272
01:41:59,510 --> 01:41:57,679
medical tent so it's going to be a

2273
01:42:01,030 --> 01:41:59,520
really exciting morning just a quick

2274
01:42:03,910 --> 01:42:01,040
note about what you saw on your screen

2275
01:42:05,990 --> 01:42:03,920
there a couple minutes ago we just had a

2276
01:42:09,109 --> 01:42:06,000
shift handover here at mission control

2277
01:42:11,830 --> 01:42:09,119
headquarters in hawthorne california so

2278
01:42:13,990 --> 01:42:11,840
our phasing shift team is now allowed to

2279
01:42:14,790 --> 01:42:14,000
go home rest they deserve it that's for

2280
01:42:17,990 --> 01:42:14,800
sure

2281
01:42:20,629 --> 01:42:18,000
and now our entry team is in position

2282
01:42:22,709 --> 01:42:20,639
and ready to support uh the re-entry and

2283
01:42:23,990 --> 01:42:22,719
splashdown phase uh here from mission

2284
01:42:25,830 --> 01:42:24,000
control

2285
01:42:27,590 --> 01:42:25,840
and we've still got a couple of hours

2286
01:42:30,550 --> 01:42:27,600
until we get into all of that right now

2287
01:42:32,629 --> 01:42:30,560
though bob and doug are awake on board

2288
01:42:35,910 --> 01:42:32,639
crew dragon endeavor they were woken up

2289
01:42:38,229 --> 01:42:35,920
at 4 40 a.m pacific time from a really

2290
01:42:40,310 --> 01:42:38,239
special message from their young boys

2291
01:42:42,149 --> 01:42:40,320
who i know are excited to get them back

2292
01:42:43,590 --> 01:42:42,159
they'll be reunited with them and once

2293
01:42:45,590 --> 01:42:43,600
they make their way back to ellington

2294
01:42:47,750 --> 01:42:45,600
airfield in houston following a

2295
01:42:49,189 --> 01:42:47,760
successful splashdown today

2296
01:42:50,629 --> 01:42:49,199
there's been quite a bit of activity

2297
01:42:53,189 --> 01:42:50,639
down here on the ground though i know we

2298
01:42:55,030 --> 01:42:53,199
just had some teams changing out inside

2299
01:42:56,790 --> 01:42:55,040
of mission control hawthorne behind us

2300
01:42:58,390 --> 01:42:56,800
which is why you can see a few more

2301
01:43:00,470 --> 01:42:58,400
people in there

2302
01:43:01,910 --> 01:43:00,480
just like control rooms around the world

2303
01:43:03,910 --> 01:43:01,920
the teams here operate in these

2304
01:43:05,669 --> 01:43:03,920
different shifts as when you have crew

2305
01:43:07,910 --> 01:43:05,679
members in outer space you're

2306
01:43:10,229 --> 01:43:07,920
responsible for watching over them and

2307
01:43:12,229 --> 01:43:10,239
the systems of your spacecraft 24 hours

2308
01:43:14,070 --> 01:43:12,239
a day seven days a week

2309
01:43:15,430 --> 01:43:14,080
and so they're going to be operating in

2310
01:43:17,430 --> 01:43:15,440
three different ships typically about

2311
01:43:18,950 --> 01:43:17,440
eight and a half to nine hours each so

2312
01:43:20,950 --> 01:43:18,960
you have a bit of overlap where you're

2313
01:43:23,030 --> 01:43:20,960
doing what we call handover

2314
01:43:25,189 --> 01:43:23,040
where you're just kind of going over

2315
01:43:26,870 --> 01:43:25,199
what occurred in the shift before you

2316
01:43:29,109 --> 01:43:26,880
what what you need to really be looking

2317
01:43:31,750 --> 01:43:29,119
out for what's coming up what what is on

2318
01:43:34,390 --> 01:43:31,760
your schedule as you i i hand you my

2319
01:43:36,709 --> 01:43:34,400
console and it's your turn to take over

2320
01:43:39,830 --> 01:43:36,719
exactly like we mentioned before in

2321
01:43:41,750 --> 01:43:39,840
terms of scheduling operations with in

2322
01:43:43,990 --> 01:43:41,760
particular for the crew sleep is really

2323
01:43:45,990 --> 01:43:44,000
important for more dynamic aspects of

2324
01:43:48,070 --> 01:43:46,000
the mission like splashdown and recovery

2325
01:43:49,109 --> 01:43:48,080
we want them to be really alert and

2326
01:43:51,430 --> 01:43:49,119
awake

2327
01:43:53,590 --> 01:43:51,440
so scheduling sleep is really important

2328
01:43:55,750 --> 01:43:53,600
for the crew schedule equally as

2329
01:43:57,669 --> 01:43:55,760
important for our

2330
01:43:59,430 --> 01:43:57,679
dragon controllers and operators here in

2331
01:44:00,629 --> 01:43:59,440
mission control so

2332
01:44:03,669 --> 01:44:00,639
that's what you just saw on your screen

2333
01:44:06,149 --> 01:44:03,679
there was the the handing of the baton

2334
01:44:08,629 --> 01:44:06,159
if you will as the two different shifts

2335
01:44:10,950 --> 01:44:08,639
now are getting into place and working

2336
01:44:13,910 --> 01:44:10,960
to get ready to support the rest of the

2337
01:44:15,270 --> 01:44:13,920
events for today

2338
01:44:17,109 --> 01:44:15,280
and we'll have

2339
01:44:18,550 --> 01:44:17,119
plenty to come up for us in a couple of

2340
01:44:21,830 --> 01:44:18,560
hours again we're just really counting

2341
01:44:23,430 --> 01:44:21,840
down until we get to deorbit burn

2342
01:44:25,109 --> 01:44:23,440
there will be a couple of steps before

2343
01:44:27,990 --> 01:44:25,119
that with trunk jettison and everything

2344
01:44:30,229 --> 01:44:28,000
like that but for now dragon continued

2345
01:44:33,109 --> 01:44:30,239
continuing to fly in orbit over planet

2346
01:44:35,189 --> 01:44:33,119
earth we are just a little over five

2347
01:44:37,189 --> 01:44:35,199
hours away five and a half hours away

2348
01:44:38,790 --> 01:44:37,199
from our anticipated splashdown yeah

2349
01:44:40,950 --> 01:44:38,800
that first event that we have coming up

2350
01:44:42,790 --> 01:44:40,960
will be claw separation

2351
01:44:45,669 --> 01:44:42,800
that is in preparation to jettison the

2352
01:44:47,350 --> 01:44:45,679
trunk and we are four hours and 38

2353
01:44:48,390 --> 01:44:47,360
minutes away from that so we hope you

2354
01:44:50,550 --> 01:44:48,400
stick with us

2355
01:44:52,470 --> 01:44:50,560
as we continue to bring coverage of

2356
01:44:55,510 --> 01:44:52,480
everything going on so far

2357
01:44:57,910 --> 01:44:55,520
like dan said uh bob and doug are awake

2358
01:45:00,149 --> 01:44:57,920
and they are completing their post sleep

2359
01:45:01,830 --> 01:45:00,159
phase although i guess they're probably

2360
01:45:03,830 --> 01:45:01,840
out of it by now since it's been more

2361
01:45:06,709 --> 01:45:03,840
than an hour since they've been woken up

2362
01:45:08,310 --> 01:45:06,719
uh but yeah so they are getting ready to

2363
01:45:09,830 --> 01:45:08,320
come on home and we're looking forward

2364
01:45:11,910 --> 01:45:09,840
to having them

2365
01:45:13,830 --> 01:45:11,920
all right and we are continuing to take

2366
01:45:16,149 --> 01:45:13,840
your questions on twitter using the

2367
01:45:18,390 --> 01:45:16,159
hashtag ask nasa you can get through a

2368
01:45:20,310 --> 01:45:18,400
couple more real quick right now

2369
01:45:22,149 --> 01:45:20,320
this one comes from ganga prabha who

2370
01:45:24,550 --> 01:45:22,159
wants to know will dragon take more than

2371
01:45:26,950 --> 01:45:24,560
two astronauts in the future it

2372
01:45:27,910 --> 01:45:26,960
absolutely will in fact in the very near

2373
01:45:29,830 --> 01:45:27,920
future

2374
01:45:32,149 --> 01:45:29,840
we're already counting down the days

2375
01:45:34,070 --> 01:45:32,159
once this mission is complete to crew

2376
01:45:36,310 --> 01:45:34,080
one that'll be the first operational

2377
01:45:38,709 --> 01:45:36,320
flight in a crew dragon spacecraft and

2378
01:45:40,629 --> 01:45:38,719
there will be four crew members on board

2379
01:45:44,470 --> 01:45:40,639
and it'll be our first multinational

2380
01:45:46,550 --> 01:45:44,480
crew to fly on this new capable vehicle

2381
01:45:48,470 --> 01:45:46,560
we'll have to do some work between the

2382
01:45:50,870 --> 01:45:48,480
end of demo two and that flight just to

2383
01:45:52,470 --> 01:45:50,880
get everything certified and ready to go

2384
01:45:54,550 --> 01:45:52,480
but that crew has already been in

2385
01:45:56,470 --> 01:45:54,560
training for several months even years

2386
01:45:58,070 --> 01:45:56,480
now for a couple of them

2387
01:46:00,790 --> 01:45:58,080
and we're looking forward to them flying

2388
01:46:02,470 --> 01:46:00,800
as early as late september yeah it's

2389
01:46:05,270 --> 01:46:02,480
really interesting you know i've been at

2390
01:46:07,750 --> 01:46:05,280
spacex for five and a half years now and

2391
01:46:09,990 --> 01:46:07,760
uh to be able to say that we're coming

2392
01:46:13,669 --> 01:46:10,000
up to our first fully operational

2393
01:46:16,070 --> 01:46:13,679
mission is is incredible uh yeah my my

2394
01:46:19,669 --> 01:46:16,080
job is to work the certification element

2395
01:46:22,790 --> 01:46:19,679
of our human space flight with nasa and

2396
01:46:23,830 --> 01:46:22,800
it's just mind-boggling and

2397
01:46:25,669 --> 01:46:23,840
um

2398
01:46:27,590 --> 01:46:25,679
that we're at the point where for so

2399
01:46:29,669 --> 01:46:27,600
many years we've been getting ready for

2400
01:46:32,149 --> 01:46:29,679
things like demo one and demo two and

2401
01:46:35,510 --> 01:46:32,159
the fact that crew one is knocking on

2402
01:46:38,629 --> 01:46:35,520
our doorstep already is amazing uh it's

2403
01:46:40,470 --> 01:46:38,639
it's really exciting time

2404
01:46:42,229 --> 01:46:40,480
all right our next one comes from annie

2405
01:46:44,229 --> 01:46:42,239
who wants to know is the crew dragon

2406
01:46:46,550 --> 01:46:44,239
trunk reusable

2407
01:46:49,910 --> 01:46:46,560
that's a good question uh right now it

2408
01:46:53,189 --> 01:46:49,920
is not uh it would be amazing to have a

2409
01:46:55,109 --> 01:46:53,199
100 reusable vehicle of course the first

2410
01:46:57,750 --> 01:46:55,119
stage in the inner stage

2411
01:47:00,149 --> 01:46:57,760
we have a number of flight proven

2412
01:47:02,550 --> 01:47:00,159
uh missions for our first first stage

2413
01:47:04,149 --> 01:47:02,560
and interstage unfortunately the trunk

2414
01:47:06,470 --> 01:47:04,159
is not something that we are able to

2415
01:47:10,470 --> 01:47:06,480
reuse we will be reusing the dragon

2416
01:47:12,629 --> 01:47:10,480
capsules themselves but after the

2417
01:47:14,870 --> 01:47:12,639
after dragon capsule uh separates from

2418
01:47:17,030 --> 01:47:14,880
the international space station uh as it

2419
01:47:19,350 --> 01:47:17,040
prepares for re-entry we will jettison

2420
01:47:22,229 --> 01:47:19,360
that trunk and it will disintegrate in

2421
01:47:24,550 --> 01:47:22,239
the earth's atmosphere as it re-enters

2422
01:47:26,550 --> 01:47:24,560
we do this because we need to expose the

2423
01:47:29,189 --> 01:47:26,560
heat shield at the bottom of the dragon

2424
01:47:30,390 --> 01:47:29,199
capsule in order to you know have a safe

2425
01:47:33,350 --> 01:47:30,400
landing

2426
01:47:35,510 --> 01:47:33,360
also the trunk is responsible for

2427
01:47:37,990 --> 01:47:35,520
carrying these solar panels which

2428
01:47:40,550 --> 01:47:38,000
provide power to the dragon capsule

2429
01:47:42,790 --> 01:47:40,560
throughout flight so since we will be

2430
01:47:45,030 --> 01:47:42,800
coming home soon and even in the event

2431
01:47:46,629 --> 01:47:45,040
of a wave off scenario where we have to

2432
01:47:48,870 --> 01:47:46,639
delay after departure from the

2433
01:47:50,950 --> 01:47:48,880
international space station and we have

2434
01:47:52,629 --> 01:47:50,960
to delay for you know whatever reason

2435
01:47:56,149 --> 01:47:52,639
that that trunk would still be able to

2436
01:47:58,390 --> 01:47:56,159
provide uh provide the unnecessary power

2437
01:48:00,870 --> 01:47:58,400
through those solar panels uh but yeah

2438
01:48:03,910 --> 01:48:00,880
so the short answer is the drunk dragon

2439
01:48:05,669 --> 01:48:03,920
the dragon trunk is not reusable at this

2440
01:48:06,550 --> 01:48:05,679
point although that would be nice

2441
01:48:08,709 --> 01:48:06,560
because

2442
01:48:13,030 --> 01:48:08,719
we won't have to build it dragon for

2443
01:48:13,040 --> 01:48:19,680
go ahead dragon with the inventory

2444
01:48:23,030 --> 01:48:21,109
[Music]

2445
01:48:25,669 --> 01:48:23,040
okay so good to hear your voice this

2446
01:48:28,390 --> 01:48:25,679
morning uh let's start with

2447
01:48:30,950 --> 01:48:28,400
location nine

2448
01:48:33,350 --> 01:48:30,960
so from bag two zero four

2449
01:48:37,189 --> 01:48:33,360
we've consumed two additional water so

2450
01:48:42,390 --> 01:48:39,430
from location 10

2451
01:48:45,030 --> 01:48:42,400
we consume two more waters from 208 so

2452
01:48:48,950 --> 01:48:45,040
bag 208 is now empty and then one

2453
01:48:56,870 --> 01:48:48,960
additional from 207 so 207 has two water

2454
01:49:02,310 --> 01:48:59,189
okay spacex copies bag

2455
01:49:03,270 --> 01:49:02,320
204 took away two waters which is now

2456
01:49:15,830 --> 01:49:03,280
empty

2457
01:49:20,390 --> 01:49:19,030
good read back for location 12 from bag

2458
01:49:23,669 --> 01:49:20,400
315

2459
01:49:26,229 --> 01:49:23,679
one breakfast i'm sorry from location 11

2460
01:49:27,750 --> 01:49:26,239
bag 315 one breakfast and then from

2461
01:49:35,990 --> 01:49:27,760
location

2462
01:49:40,229 --> 01:49:37,910
okay bob we copy

2463
01:49:41,109 --> 01:49:40,239
one breakfast down from bag three one

2464
01:49:44,550 --> 01:49:41,119
five

2465
01:49:47,030 --> 01:49:44,560
and uh one breakfast down from bag 319.

2466
01:49:47,830 --> 01:49:47,040
it is also great to hear you guys as

2467
01:49:50,070 --> 01:49:47,840
well

2468
01:49:57,270 --> 01:49:50,080
and a request to come back aboard when

2469
01:50:01,430 --> 01:49:59,350
okay so uh we'll give you a call here in

2470
01:50:01,770 --> 01:50:01,440
just a couple minutes to come back on

2471
01:50:03,990 --> 01:50:01,780
board

2472
01:50:12,390 --> 01:50:04,000
[Applause]

2473
01:50:17,750 --> 01:50:16,070
all right so that exchange

2474
01:50:18,950 --> 01:50:17,760
that that exchange right there real

2475
01:50:21,109 --> 01:50:18,960
quick was

2476
01:50:22,310 --> 01:50:21,119
really just an inventory uh

2477
01:50:23,750 --> 01:50:22,320
believe it or not one of the hardest

2478
01:50:26,229 --> 01:50:23,760
things about space flight is just

2479
01:50:27,990 --> 01:50:26,239
keeping track of everything

2480
01:50:29,830 --> 01:50:28,000
things tend to float around and get lost

2481
01:50:32,550 --> 01:50:29,840
in microgravity pretty easily there's a

2482
01:50:34,229 --> 01:50:32,560
couple of stories of wanted posters for

2483
01:50:36,310 --> 01:50:34,239
items onboard the international space

2484
01:50:38,390 --> 01:50:36,320
station when they go missing

2485
01:50:40,149 --> 01:50:38,400
and even on the station which

2486
01:50:42,310 --> 01:50:40,159
much bigger than just the crew dragon

2487
01:50:44,229 --> 01:50:42,320
itself they have very

2488
01:50:47,750 --> 01:50:44,239
intricate system to track everything

2489
01:50:49,589 --> 01:50:47,760
through rfid and very meticulous ground

2490
01:50:52,470 --> 01:50:49,599
annotations like we were just hearing

2491
01:50:54,229 --> 01:50:52,480
read off so if a crew member ever gets

2492
01:50:56,470 --> 01:50:54,239
in a situation where they need to find

2493
01:50:58,070 --> 01:50:56,480
something you have people dedicated here

2494
01:51:00,070 --> 01:50:58,080
on the ground who will know exactly

2495
01:51:01,990 --> 01:51:00,080
where that is it always kind of blows me

2496
01:51:03,910 --> 01:51:02,000
away when they can you can give them an

2497
01:51:06,550 --> 01:51:03,920
item and they can tell you it's in this

2498
01:51:09,189 --> 01:51:06,560
rack in this bag this is also in that

2499
01:51:11,430 --> 01:51:09,199
bag this is what this is exactly where

2500
01:51:13,270 --> 01:51:11,440
you will find it yeah that would be a

2501
01:51:14,950 --> 01:51:13,280
very extensive list especially for the

2502
01:51:15,990 --> 01:51:14,960
items on board the international space

2503
01:51:17,430 --> 01:51:16,000
station

2504
01:51:19,830 --> 01:51:17,440
what they were reporting there was

2505
01:51:21,589 --> 01:51:19,840
essentially what they've consumed both

2506
01:51:22,870 --> 01:51:21,599
liquid and food

2507
01:51:25,510 --> 01:51:22,880
over the last couple of hours just

2508
01:51:27,830 --> 01:51:25,520
documenting their fluid intake and

2509
01:51:29,750 --> 01:51:27,840
the meal consumption also that to

2510
01:51:32,310 --> 01:51:29,760
translate that request to come back on

2511
01:51:34,149 --> 01:51:32,320
board that is requesting permission to

2512
01:51:36,390 --> 01:51:34,159
let the cameras turn back on of course

2513
01:51:39,510 --> 01:51:36,400
for privacy reasons uh during the sleep

2514
01:51:41,750 --> 01:51:39,520
phase and their wake-up um the the

2515
01:51:43,830 --> 01:51:41,760
post-sleep phase as they're waking up

2516
01:51:46,229 --> 01:51:43,840
and stretching their legs your cameras

2517
01:51:48,390 --> 01:51:46,239
are turned off for the crew privacy so

2518
01:51:50,709 --> 01:51:48,400
that was just our core here in mission

2519
01:51:52,229 --> 01:51:50,719
control requesting uh to have those

2520
01:51:53,669 --> 01:51:52,239
cameras turned back on

2521
01:51:56,229 --> 01:51:53,679
so hopefully we get some views over

2522
01:51:58,149 --> 01:51:56,239
their shoulder or just inside the cabin

2523
01:52:00,229 --> 01:51:58,159
in just a little bit

2524
01:52:02,870 --> 01:52:00,239
but again for for rob and doug they're

2525
01:52:04,709 --> 01:52:02,880
finishing up that post-sleep period

2526
01:52:06,310 --> 01:52:04,719
and so they're really just going to be

2527
01:52:07,990 --> 01:52:06,320
kind of getting getting their house in

2528
01:52:10,870 --> 01:52:08,000
order really getting dragon ready for

2529
01:52:13,350 --> 01:52:10,880
that re-entry they'll have some steps uh

2530
01:52:15,510 --> 01:52:13,360
just to get suited up and get positioned

2531
01:52:16,470 --> 01:52:15,520
into the dragon space inside dragon

2532
01:52:18,790 --> 01:52:16,480
itself

2533
01:52:20,870 --> 01:52:18,800
where they're going to be monitoring

2534
01:52:22,870 --> 01:52:20,880
the the d-orbit burn all the different

2535
01:52:24,709 --> 01:52:22,880
events on their touch screen displays

2536
01:52:26,950 --> 01:52:24,719
they're going to be able to see changes

2537
01:52:29,109 --> 01:52:26,960
in orbit changes in velocity

2538
01:52:30,790 --> 01:52:29,119
all just the really critical

2539
01:52:32,390 --> 01:52:30,800
bits of data to tell them how the

2540
01:52:34,470 --> 01:52:32,400
performance of these burns and these

2541
01:52:36,229 --> 01:52:34,480
different activities are going they're

2542
01:52:38,870 --> 01:52:36,239
going to be able to tell exactly what

2543
01:52:41,430 --> 01:52:38,880
orbit they're on and see when it lines

2544
01:52:43,589 --> 01:52:41,440
up with the coast or with the ocean just

2545
01:52:45,109 --> 01:52:43,599
off the coast of pensacola florida a

2546
01:52:47,990 --> 01:52:45,119
little bit later

2547
01:52:50,950 --> 01:52:48,000
they'll largely be in a monitor mode as

2548
01:52:53,270 --> 01:52:50,960
dragon is designed to fly autonomously

2549
01:52:55,430 --> 01:52:53,280
and kind of guide itself back but they

2550
01:52:57,189 --> 01:52:55,440
are in the loop essentially where they

2551
01:53:00,149 --> 01:52:57,199
could jump in and be that backup

2552
01:53:01,830 --> 01:53:00,159
capability if required yeah as dan said

2553
01:53:04,470 --> 01:53:01,840
that they'll be putting their suits back

2554
01:53:06,149 --> 01:53:04,480
on here shortly uh we only have them

2555
01:53:08,550 --> 01:53:06,159
wear the suits for the more dynamic

2556
01:53:10,470 --> 01:53:08,560
phases uh whenever they are inside the

2557
01:53:11,669 --> 01:53:10,480
capsule so obviously we want them to

2558
01:53:13,750 --> 01:53:11,679
have that on

2559
01:53:15,350 --> 01:53:13,760
as they re-enter the atmosphere so

2560
01:53:16,790 --> 01:53:15,360
they'll put it on well before we begin

2561
01:53:18,709 --> 01:53:16,800
those de-orbit

2562
01:53:21,430 --> 01:53:18,719
those deorbit sequences

2563
01:53:23,270 --> 01:53:21,440
that being said they were able to sleep

2564
01:53:25,109 --> 01:53:23,280
therefore they were able to sleep not in

2565
01:53:27,030 --> 01:53:25,119
their in their suits

2566
01:53:29,510 --> 01:53:27,040
and comfortably in their chairs with a

2567
01:53:31,589 --> 01:53:29,520
little bit more wiggle room there

2568
01:53:32,709 --> 01:53:31,599
something else to note that we have

2569
01:53:34,310 --> 01:53:32,719
coming up

2570
01:53:36,310 --> 01:53:34,320
hopefully we'll like dan said we'll get

2571
01:53:39,189 --> 01:53:36,320
some of those camera views

2572
01:53:41,189 --> 01:53:39,199
coming from inside the cabin and

2573
01:53:43,910 --> 01:53:41,199
well like i mentioned before something

2574
01:53:46,149 --> 01:53:43,920
that i really like being able to see is

2575
01:53:48,629 --> 01:53:46,159
the the shot between the two of them

2576
01:53:51,030 --> 01:53:48,639
looking at the actual display panels

2577
01:53:52,070 --> 01:53:51,040
themselves uh we'll actually be able to

2578
01:53:55,750 --> 01:53:52,080
see

2579
01:53:58,709 --> 01:53:55,760
they are monitoring all the telemetry

2580
01:54:02,070 --> 01:53:58,719
and data and attitude information as the

2581
01:54:03,350 --> 01:54:02,080
capsule is re-entering the atmosphere so

2582
01:54:04,790 --> 01:54:03,360
we are going to continue to take your

2583
01:54:07,750 --> 01:54:04,800
questions through

2584
01:54:09,270 --> 01:54:07,760
ask nasa on twitter our next question

2585
01:54:11,189 --> 01:54:09,280
comes from christian

2586
01:54:13,830 --> 01:54:11,199
what ensures that the capsule does not

2587
01:54:15,830 --> 01:54:13,840
melt upon re-entry please explain the

2588
01:54:17,030 --> 01:54:15,840
thermal protection yeah that's a great

2589
01:54:17,750 --> 01:54:17,040
question

2590
01:54:23,270 --> 01:54:17,760
one

2591
01:54:24,550 --> 01:54:23,280
hardware on our dragon capsules is the

2592
01:54:26,470 --> 01:54:24,560
heat shield

2593
01:54:29,430 --> 01:54:26,480
part of my job is to work with nasa to

2594
01:54:31,669 --> 01:54:29,440
certify the heat shield and so i am very

2595
01:54:34,470 --> 01:54:31,679
lucky that i get to work

2596
01:54:37,430 --> 01:54:34,480
you're clear to come on board anytime

2597
01:54:38,870 --> 01:54:37,440
all right all right okay doug copy uh

2598
01:54:42,229 --> 01:54:38,880
welcome aboard we should get that in

2599
01:54:44,149 --> 01:54:42,239
work shortly um in addition uh as able

2600
01:54:46,550 --> 01:54:44,159
when you're ready request your game plan

2601
01:54:47,430 --> 01:54:46,560
for fluid loading water this corresponds

2602
01:54:49,430 --> 01:54:47,440
to

2603
01:54:58,149 --> 01:54:49,440
section three of four decimal seven zero

2604
01:55:03,109 --> 01:55:00,550
so that call out that we heard there was

2605
01:55:05,350 --> 01:55:03,119
inviting us to turn the cameras back on

2606
01:55:09,990 --> 01:55:05,360
inside the capsule okay i think our plan

2607
01:55:12,390 --> 01:55:10,000
is uh as prescribed um

2608
01:55:14,470 --> 01:55:12,400
and then i will be drinking water out of

2609
01:55:16,390 --> 01:55:14,480
the other corresponding probably all

2610
01:55:18,629 --> 01:55:16,400
three of those bottles and bob's

2611
01:55:20,950 --> 01:55:18,639
probably gonna have to break into his

2612
01:55:32,470 --> 01:55:20,960
corresponding bag as well as potentially

2613
01:55:36,790 --> 01:55:35,350
okay uh copy doug so basically uh we

2614
01:55:39,109 --> 01:55:36,800
were saying the bottles you expect to

2615
01:55:40,870 --> 01:55:39,119
remove are the ones you just spoke about

2616
01:55:43,030 --> 01:55:40,880
during a breakfast as well as one

2617
01:55:47,350 --> 01:55:43,040
additional one from volume 10 is that an

2618
01:55:54,070 --> 01:55:49,510
uh negative i think it's gonna be one

2619
01:55:57,750 --> 01:55:56,149
okay copy um we'll probably tag up with

2620
01:56:02,229 --> 01:55:57,760
you after fluid loading complete just to

2621
01:56:05,990 --> 01:56:03,990
yeah that sounds good mike i think

2622
01:56:07,910 --> 01:56:06,000
that's probably best because it might be

2623
01:56:11,510 --> 01:56:07,920
somewhat variable but i think it's

2624
01:56:16,629 --> 01:56:14,709
okay copy thank you

2625
01:56:19,510 --> 01:56:16,639
so that conversation there about fluid

2626
01:56:20,950 --> 01:56:19,520
loading the official space way of saying

2627
01:56:22,470 --> 01:56:20,960
drink your water

2628
01:56:23,350 --> 01:56:22,480
making sure that bob and doug will

2629
01:56:26,229 --> 01:56:23,360
remain

2630
01:56:29,669 --> 01:56:26,239
hydrated throughout the reentry period

2631
01:56:31,350 --> 01:56:29,679
if you fly on airplanes that's you if

2632
01:56:32,709 --> 01:56:31,360
you do your research it's important to

2633
01:56:35,189 --> 01:56:32,719
stay hydrated while you're flying on

2634
01:56:36,870 --> 01:56:35,199
airplanes due to the different pressures

2635
01:56:38,550 --> 01:56:36,880
uh your body tends to lose a little bit

2636
01:56:40,629 --> 01:56:38,560
more water and so it's important to

2637
01:56:42,870 --> 01:56:40,639
continue to drink water to stay hydrated

2638
01:56:44,390 --> 01:56:42,880
same here for bob and doug you heard

2639
01:56:46,870 --> 01:56:44,400
them mention

2640
01:56:49,270 --> 01:56:46,880
as surprised oh there we can see them

2641
01:56:50,790 --> 01:56:49,280
in their capsule there is

2642
01:56:53,189 --> 01:56:50,800
doug hurley there

2643
01:56:54,550 --> 01:56:53,199
reading his instructions

2644
01:56:57,910 --> 01:56:54,560
looks like

2645
01:56:59,430 --> 01:56:57,920
he's wearing a blue sweatshirt there

2646
01:57:02,070 --> 01:56:59,440
drinking some water

2647
01:57:02,950 --> 01:57:02,080
uh yeah so they're just checking to make

2648
01:57:06,149 --> 01:57:02,960
sure

2649
01:57:07,589 --> 01:57:06,159
there's the back of doug's head

2650
01:57:09,350 --> 01:57:07,599
just to make sure that they are drinking

2651
01:57:10,629 --> 01:57:09,360
enough water you heard them mention as

2652
01:57:13,510 --> 01:57:10,639
prescribed

2653
01:57:15,510 --> 01:57:13,520
that is that inten excuse me that means

2654
01:57:16,790 --> 01:57:15,520
that our flight surgeon is prescribing

2655
01:57:18,390 --> 01:57:16,800
them how much water they should be

2656
01:57:20,390 --> 01:57:18,400
drinking whether or not they should be

2657
01:57:21,510 --> 01:57:20,400
taking salt tablets to help them retain

2658
01:57:23,589 --> 01:57:21,520
that water

2659
01:57:25,669 --> 01:57:23,599
as they are making their journey back

2660
01:57:27,750 --> 01:57:25,679
home

2661
01:57:29,270 --> 01:57:27,760
so going yeah here's here's that view

2662
01:57:31,669 --> 01:57:29,280
we've talked about a couple of times

2663
01:57:33,510 --> 01:57:31,679
looking directly over their shoulders

2664
01:57:36,149 --> 01:57:33,520
and so you have those three main

2665
01:57:38,390 --> 01:57:36,159
touchscreen displays and they can

2666
01:57:40,629 --> 01:57:38,400
configure them in a number of different

2667
01:57:41,910 --> 01:57:40,639
modes it looks like the one they have in

2668
01:57:43,270 --> 01:57:41,920
the middle is giving them their

2669
01:57:44,550 --> 01:57:43,280
trajectory

2670
01:57:47,430 --> 01:57:44,560
they had one on the right that was

2671
01:57:49,510 --> 01:57:47,440
looking at a lot of the different

2672
01:57:50,870 --> 01:57:49,520
control systems and

2673
01:57:53,510 --> 01:57:50,880
they get everything from current

2674
01:57:56,149 --> 01:57:53,520
velocity altitude they can get deep

2675
01:57:58,229 --> 01:57:56,159
insight into their life support system

2676
01:57:59,510 --> 01:57:58,239
all of the pyrotechnics on board all the

2677
01:58:01,510 --> 01:57:59,520
different things of the dragon

2678
01:58:03,830 --> 01:58:01,520
spacecraft those displays are really

2679
01:58:06,149 --> 01:58:03,840
their window into it you'll also notice

2680
01:58:08,070 --> 01:58:06,159
a couple of illuminated buttons

2681
01:58:11,189 --> 01:58:08,080
underneath the touch screens

2682
01:58:13,830 --> 01:58:11,199
some of the really critical functions

2683
01:58:16,229 --> 01:58:13,840
that require immediate action get a

2684
01:58:18,390 --> 01:58:16,239
button dedicated to them for example

2685
01:58:21,510 --> 01:58:18,400
they have buttons for a number number of

2686
01:58:24,070 --> 01:58:21,520
the pyro uh events on board the dragon

2687
01:58:26,950 --> 01:58:24,080
spacecraft like parachute deploy or the

2688
01:58:29,510 --> 01:58:26,960
ability to cut those parachutes once

2689
01:58:30,709 --> 01:58:29,520
they splash down in the water

2690
01:58:32,550 --> 01:58:30,719
and so they're going to get these

2691
01:58:34,870 --> 01:58:32,560
configured and this is going to be how

2692
01:58:36,310 --> 01:58:34,880
they track the progress of their flight

2693
01:58:38,870 --> 01:58:36,320
home today

2694
01:58:40,950 --> 01:58:38,880
yeah if we get that view back between

2695
01:58:42,790 --> 01:58:40,960
their heads on the left-hand side of the

2696
01:58:44,470 --> 01:58:42,800
screen there we go the left-hand side of

2697
01:58:46,629 --> 01:58:44,480
your screen there is actually the

2698
01:58:49,430 --> 01:58:46,639
control display that they'll be using

2699
01:58:51,910 --> 01:58:49,440
for the re-entry excuse me for the

2700
01:58:53,030 --> 01:58:51,920
de-orbit burn there's a number of

2701
01:58:54,950 --> 01:58:53,040
there's a bunch of information that'll

2702
01:58:57,589 --> 01:58:54,960
be displayed there like trajectory

2703
01:58:59,910 --> 01:58:57,599
details such as entry angle and capsule

2704
01:59:01,030 --> 01:58:59,920
perigee and how much distance is

2705
01:59:03,750 --> 01:59:01,040
remaining

2706
01:59:05,830 --> 01:59:03,760
between the current time and

2707
01:59:07,350 --> 01:59:05,840
and whenever that deorbit burn is

2708
01:59:08,950 --> 01:59:07,360
terminated

2709
01:59:10,229 --> 01:59:08,960
so yeah a lot of really important

2710
01:59:12,709 --> 01:59:10,239
information there for them they'll also

2711
01:59:14,870 --> 01:59:12,719
be able to see which of the four

2712
01:59:18,310 --> 01:59:14,880
draco thrusters are firing at any given

2713
01:59:20,229 --> 01:59:18,320
time during that do orbit burn so that's

2714
01:59:21,830 --> 01:59:20,239
uh we'll will probably see that

2715
01:59:25,109 --> 01:59:21,840
particular screen on both of their

2716
01:59:27,270 --> 01:59:25,119
screens during that phase of the mission

2717
01:59:29,669 --> 01:59:27,280
so going back to the previous question

2718
01:59:31,189 --> 01:59:29,679
that we had from hashtag ask nasa came

2719
01:59:32,950 --> 01:59:31,199
to us from christian

2720
01:59:34,870 --> 01:59:32,960
he asked what ensures that the capsule

2721
01:59:37,189 --> 01:59:34,880
does not melt upon re-entry please

2722
01:59:39,189 --> 01:59:37,199
explain thermal protection i was just

2723
01:59:40,310 --> 01:59:39,199
saying that my job here as a spacex

2724
01:59:42,629 --> 01:59:40,320
engineer

2725
01:59:44,470 --> 01:59:42,639
i have the awesome opportunity to work

2726
01:59:46,709 --> 01:59:44,480
with our heat shield experts both on the

2727
01:59:48,790 --> 01:59:46,719
spacex side and nasa's heat shield

2728
01:59:51,669 --> 01:59:48,800
experts and really get the stamp of

2729
01:59:53,030 --> 01:59:51,679
approval to use the hardware for flight

2730
01:59:55,830 --> 01:59:53,040
it is

2731
01:59:57,990 --> 01:59:55,840
you can think of it kind of like a pizza

2732
01:59:59,669 --> 01:59:58,000
there is the base of the heat shield or

2733
02:00:01,990 --> 01:59:59,679
the shape the structure

2734
02:00:03,270 --> 02:00:02,000
and that's made out of carbon fiber we

2735
02:00:04,790 --> 02:00:03,280
and that you can think of that as the

2736
02:00:06,470 --> 02:00:04,800
crust

2737
02:00:08,709 --> 02:00:06,480
we then apply

2738
02:00:11,030 --> 02:00:08,719
a coating to it that allows the

2739
02:00:13,350 --> 02:00:11,040
individual heat shields the individual

2740
02:00:14,470 --> 02:00:13,360
tiles of the heat shield themselves to

2741
02:00:16,870 --> 02:00:14,480
stick to

2742
02:00:18,310 --> 02:00:16,880
the the structure itself so

2743
02:00:20,629 --> 02:00:18,320
what we use to adhere it you can think

2744
02:00:23,430 --> 02:00:20,639
of as the sauce and you can think of

2745
02:00:24,709 --> 02:00:23,440
those tiles as the pepperoni pieces on

2746
02:00:27,510 --> 02:00:24,719
your pizza

2747
02:00:29,510 --> 02:00:27,520
so it's kind of a

2748
02:00:31,109 --> 02:00:29,520
different way to explain it but that's

2749
02:00:34,229 --> 02:00:31,119
how i like to think of it

2750
02:00:35,750 --> 02:00:34,239
the heat shield again is responsible for

2751
02:00:39,030 --> 02:00:35,760
really protecting the capsule those

2752
02:00:42,550 --> 02:00:39,040
temperatures will get up to 3500 degrees

2753
02:00:44,790 --> 02:00:42,560
fahrenheit so pretty toasty we will i'm

2754
02:00:46,950 --> 02:00:44,800
sure have a great shot of our toasted

2755
02:00:49,430 --> 02:00:46,960
marshmallow back on the recovery vessel

2756
02:00:51,669 --> 02:00:49,440
once it splashes down but yes that heat

2757
02:00:54,709 --> 02:00:51,679
shield does the bulk of the thermal

2758
02:00:56,790 --> 02:00:54,719
protective work there are of course

2759
02:00:57,750 --> 02:00:56,800
panels on the exterior of the dragon

2760
02:00:59,669 --> 02:00:57,760
capsule

2761
02:01:01,830 --> 02:00:59,679
i mentioned toasted marshmallow those

2762
02:01:04,229 --> 02:01:01,840
white panels that are on the exterior

2763
02:01:05,830 --> 02:01:04,239
will also become brown as it as it

2764
02:01:07,750 --> 02:01:05,840
re-enters the atmosphere

2765
02:01:10,149 --> 02:01:07,760
and begins to char due to all of the

2766
02:01:11,350 --> 02:01:10,159
heat and the plasma buildup so really

2767
02:01:13,109 --> 02:01:11,360
good question

2768
02:01:14,629 --> 02:01:13,119
of course with all those external

2769
02:01:16,070 --> 02:01:14,639
temperatures getting so hot it is

2770
02:01:17,990 --> 02:01:16,080
important to keep bob and doug

2771
02:01:20,470 --> 02:01:18,000
comfortable in their return

2772
02:01:23,589 --> 02:01:20,480
there there will be cool nitrox purging

2773
02:01:25,750 --> 02:01:23,599
through the cabin of the capsule itself

2774
02:01:28,070 --> 02:01:25,760
as well as through their suits

2775
02:01:30,550 --> 02:01:28,080
any time the the telemetry excuse me

2776
02:01:32,870 --> 02:01:30,560
anytime the suits detect that their the

2777
02:01:34,229 --> 02:01:32,880
suit internal suit temperature

2778
02:01:36,470 --> 02:01:34,239
is getting too high i think the

2779
02:01:38,629 --> 02:01:36,480
threshold is 85 degrees fahrenheit it'll

2780
02:01:39,750 --> 02:01:38,639
purge the suit with some cold air so bob

2781
02:01:42,149 --> 02:01:39,760
and doug will

2782
02:01:43,589 --> 02:01:42,159
will remain comfortable throughout their

2783
02:01:46,149 --> 02:01:43,599
journey back through the earth's

2784
02:01:47,510 --> 02:01:46,159
atmosphere

2785
02:01:51,109 --> 02:01:47,520
pizza

2786
02:01:53,430 --> 02:01:51,119
thank you kate all right our next

2787
02:01:55,830 --> 02:01:53,440
question comes from kevin who wanted to

2788
02:01:56,709 --> 02:01:55,840
know when does dragon start its deorbit

2789
02:01:59,030 --> 02:01:56,719
burn

2790
02:02:01,350 --> 02:01:59,040
and we can give you the exact time down

2791
02:02:02,790 --> 02:02:01,360
to the second of when it's targeted

2792
02:02:08,149 --> 02:02:02,800
right now

2793
02:02:10,070 --> 02:02:08,159
it's at 10 56 and 45 seconds pacific

2794
02:02:13,830 --> 02:02:10,080
and then if you convert that over to

2795
02:02:15,510 --> 02:02:13,840
greenwich mean time 17 56 and 45 seconds

2796
02:02:18,470 --> 02:02:15,520
yeah so we're just under four and a half

2797
02:02:19,189 --> 02:02:18,480
hours until we begin that deorbit burn

2798
02:02:21,109 --> 02:02:19,199
so

2799
02:02:23,350 --> 02:02:21,119
kevin if you're looking to take a little

2800
02:02:25,830 --> 02:02:23,360
bit of a nap between now and deorbit

2801
02:02:28,709 --> 02:02:25,840
you've got a little bit of time

2802
02:02:30,790 --> 02:02:28,719
our next question comes to us from

2803
02:02:32,950 --> 02:02:30,800
w stelmak

2804
02:02:35,030 --> 02:02:32,960
the question is can you become taller

2805
02:02:37,669 --> 02:02:35,040
after spending a long time in space

2806
02:02:41,830 --> 02:02:37,679
great question the answer is yes

2807
02:02:42,629 --> 02:02:41,840
due to the lack of strong gravity pull

2808
02:02:45,270 --> 02:02:42,639
on

2809
02:02:47,750 --> 02:02:45,280
the human body we have found that

2810
02:02:50,229 --> 02:02:47,760
astronauts actually report growing in

2811
02:02:52,470 --> 02:02:50,239
length uh due to the fact that their

2812
02:02:55,350 --> 02:02:52,480
body isn't being compressed in this

2813
02:02:57,830 --> 02:02:55,360
direction vertically uh according to our

2814
02:03:00,470 --> 02:02:57,840
orientation on the earth's surface uh

2815
02:03:03,030 --> 02:03:00,480
yeah because there's lack of gravity

2816
02:03:04,790 --> 02:03:03,040
compressing the body we do see reports

2817
02:03:07,030 --> 02:03:04,800
of the astronauts saying that they got a

2818
02:03:08,790 --> 02:03:07,040
little taller in space yeah we you can

2819
02:03:10,310 --> 02:03:08,800
kind of think about it where you you've

2820
02:03:11,750 --> 02:03:10,320
been told you're the tallest when you

2821
02:03:13,750 --> 02:03:11,760
first wake up because you've been

2822
02:03:16,070 --> 02:03:13,760
horizontal the whole time

2823
02:03:18,550 --> 02:03:16,080
and it is a temporary getting taller

2824
02:03:21,350 --> 02:03:18,560
once they return back to earth there

2825
02:03:23,510 --> 02:03:21,360
they shrink back down pretty quick

2826
02:03:26,070 --> 02:03:23,520
but keep sending in your questions using

2827
02:03:27,589 --> 02:03:26,080
the hashtag ask nasa said we still have

2828
02:03:30,070 --> 02:03:27,599
a few more hours until we get to the

2829
02:03:31,510 --> 02:03:30,080
deorbit burn which is when things really

2830
02:03:32,950 --> 02:03:31,520
start to pick up

2831
02:03:35,030 --> 02:03:32,960
just to run down a couple of those

2832
02:03:37,109 --> 02:03:35,040
milestones again for you

2833
02:03:38,950 --> 02:03:37,119
prior to the deorbit burn we have to get

2834
02:03:40,870 --> 02:03:38,960
rid of dragon's trunk

2835
02:03:43,430 --> 02:03:40,880
and so what we'll be doing is first

2836
02:03:45,109 --> 02:03:43,440
doing a slew or a maneuver to alter

2837
02:03:46,629 --> 02:03:45,119
dragon's attitude

2838
02:03:48,149 --> 02:03:46,639
and then just get it ready for this

2839
02:03:49,990 --> 02:03:48,159
trunk separation

2840
02:03:53,910 --> 02:03:50,000
that's scheduled to happen

2841
02:03:56,229 --> 02:03:53,920
right at about 10 48 a.m pacific 1748

2842
02:03:58,709 --> 02:03:56,239
gmt after dragon's in the correct

2843
02:04:00,229 --> 02:03:58,719
attitude it'll first separate the claw

2844
02:04:02,149 --> 02:04:00,239
which is the connecting point between

2845
02:04:03,910 --> 02:04:02,159
the trunk and the capsule itself

2846
02:04:06,950 --> 02:04:03,920
followed shortly after by the trunk the

2847
02:04:10,870 --> 02:04:06,960
trunk scheduled to separate at 10 51 am

2848
02:04:13,350 --> 02:04:10,880
pacific 1751 gmt and then after the

2849
02:04:16,069 --> 02:04:13,360
trunk has been separated we get into the

2850
02:04:17,750 --> 02:04:16,079
proper deorbit burn for that final burn

2851
02:04:20,229 --> 02:04:17,760
that's going to be sending them on home

2852
02:04:22,470 --> 02:04:20,239
yeah that burn will last about 11 and a

2853
02:04:25,030 --> 02:04:22,480
half minutes and we'll be using the

2854
02:04:27,189 --> 02:04:25,040
forward bulkhead draco thrusters

2855
02:04:29,350 --> 02:04:27,199
once the deorbit burn completes we'll no

2856
02:04:31,270 --> 02:04:29,360
longer need to utilize or fire those

2857
02:04:32,550 --> 02:04:31,280
particular thrusters so we will close

2858
02:04:35,270 --> 02:04:32,560
the nose cone

2859
02:04:37,350 --> 02:04:35,280
protecting them as well as the forward

2860
02:04:38,629 --> 02:04:37,360
hatch from reentry

2861
02:04:41,030 --> 02:04:38,639
conditions

2862
02:04:44,790 --> 02:04:41,040
about 20 minutes after that the fun

2863
02:04:46,550 --> 02:04:44,800
stuff begins at 11 36 a.m pacific or

2864
02:04:49,030 --> 02:04:46,560
1836

2865
02:04:51,589 --> 02:04:49,040
universal time we will have an expected

2866
02:04:53,669 --> 02:04:51,599
loss of signal communications blackout

2867
02:04:55,910 --> 02:04:53,679
that will last about six minutes during

2868
02:04:58,229 --> 02:04:55,920
that time we won't be able to command

2869
02:04:59,750 --> 02:04:58,239
dragon or receive telemetry or

2870
02:05:01,750 --> 02:04:59,760
communicate with the crew that being

2871
02:05:04,229 --> 02:05:01,760
said dragon is designed to be completely

2872
02:05:05,669 --> 02:05:04,239
autonomous it is steering itself at that

2873
02:05:07,750 --> 02:05:05,679
point anyway

2874
02:05:09,350 --> 02:05:07,760
that blackout will last like i said for

2875
02:05:11,669 --> 02:05:09,360
six minutes

2876
02:05:13,350 --> 02:05:11,679
in the middle of there we are just a

2877
02:05:15,750 --> 02:05:13,360
couple minutes after that blackout

2878
02:05:17,990 --> 02:05:15,760
period begins we will have what's known

2879
02:05:19,990 --> 02:05:18,000
as entry interface this is when

2880
02:05:21,589 --> 02:05:20,000
the capsule is really beginning to enter

2881
02:05:23,589 --> 02:05:21,599
the earth's atmosphere it's beginning to

2882
02:05:25,669 --> 02:05:23,599
feel the friction and the aerodynamic

2883
02:05:27,510 --> 02:05:25,679
forces associated with hitting that

2884
02:05:30,790 --> 02:05:27,520
atmosphere uh we'll get those

2885
02:05:33,669 --> 02:05:30,800
communications back at 11 42 a.m pacific

2886
02:05:35,030 --> 02:05:33,679
or 1842 universal

2887
02:05:39,189 --> 02:05:35,040
just two minutes after we get

2888
02:05:41,430 --> 02:05:39,199
communications back we will have our

2889
02:05:43,750 --> 02:05:41,440
the drogue chute deployment there are

2890
02:05:44,709 --> 02:05:43,760
three smaller drogue parachutes that

2891
02:05:45,750 --> 02:05:44,719
will

2892
02:05:48,629 --> 02:05:45,760
pop out

2893
02:05:49,830 --> 02:05:48,639
at 11 44 am pacific and those are

2894
02:05:51,430 --> 02:05:49,840
designed to

2895
02:05:54,709 --> 02:05:51,440
slow the capsule continue to slow the

2896
02:05:56,629 --> 02:05:54,719
capsule down further beyond what the

2897
02:05:58,390 --> 02:05:56,639
slowing of the capsule from the

2898
02:06:00,709 --> 02:05:58,400
atmosphere those stroke shoots will

2899
02:06:03,270 --> 02:06:00,719
continue to slow it down

2900
02:06:05,669 --> 02:06:03,280
those stroke shoots will release about a

2901
02:06:08,390 --> 02:06:05,679
minute later and we will see those main

2902
02:06:10,069 --> 02:06:08,400
parachutes deploy for orange and white

2903
02:06:11,669 --> 02:06:10,079
big old parachutes will come out and

2904
02:06:12,870 --> 02:06:11,679
continue to further decelerate the

2905
02:06:16,149 --> 02:06:12,880
vehicle

2906
02:06:18,229 --> 02:06:16,159
at that point it will be going from 350

2907
02:06:20,709 --> 02:06:18,239
miles per hour so originally the the

2908
02:06:23,750 --> 02:06:20,719
velocity during the deorbit phase

2909
02:06:25,589 --> 02:06:23,760
exactly while on station is 17 500 miles

2910
02:06:27,350 --> 02:06:25,599
per hour as it continues to rotate

2911
02:06:30,390 --> 02:06:27,360
around earth still going that fast we'll

2912
02:06:32,229 --> 02:06:30,400
come down to 350 miles per hour as it

2913
02:06:34,470 --> 02:06:32,239
re-enters the atmosphere

2914
02:06:35,589 --> 02:06:34,480
the parachutes will further decelerate

2915
02:06:38,950 --> 02:06:35,599
it to

2916
02:06:41,350 --> 02:06:38,960
a mere 15 or 16 miles per hour

2917
02:06:42,229 --> 02:06:41,360
as it touches down into the atlantic

2918
02:06:44,229 --> 02:06:42,239
ocean

2919
02:06:48,310 --> 02:06:44,239
we are anticipating that splashdown to

2920
02:06:50,790 --> 02:06:48,320
occur at 11 48 a.m pacific or 1848

2921
02:06:53,510 --> 02:06:50,800
universal uh and at that point in time

2922
02:06:55,510 --> 02:06:53,520
our recovery operations will begin and

2923
02:06:57,830 --> 02:06:55,520
that is something that we are all very

2924
02:06:59,510 --> 02:06:57,840
excited to see yeah i mean the clock

2925
02:07:02,390 --> 02:06:59,520
starts ticking almost from the moment

2926
02:07:04,790 --> 02:07:02,400
they hit the water and the teams move to

2927
02:07:07,109 --> 02:07:04,800
work extremely quickly but also

2928
02:07:08,709 --> 02:07:07,119
keeping safety kind of at the forefront

2929
02:07:11,109 --> 02:07:08,719
of everything that they're doing this is

2930
02:07:13,589 --> 02:07:11,119
the first time we've returned a crew to

2931
02:07:15,430 --> 02:07:13,599
a splashdown since apollo since the very

2932
02:07:19,589 --> 02:07:15,440
last apollo mission the apollo so used

2933
02:07:21,510 --> 02:07:19,599
test project back in july of 1975. so

2934
02:07:22,950 --> 02:07:21,520
it's something we haven't done in a long

2935
02:07:25,030 --> 02:07:22,960
time but it's something that we've

2936
02:07:27,109 --> 02:07:25,040
definitely rehearsed many times for this

2937
02:07:29,350 --> 02:07:27,119
moment including on our demonstration

2938
02:07:30,550 --> 02:07:29,360
flight just last year so the teams are

2939
02:07:32,149 --> 02:07:30,560
going to move in extremely quickly

2940
02:07:34,390 --> 02:07:32,159
within the first couple of minutes of

2941
02:07:36,550 --> 02:07:34,400
splashdown just to get the capsule

2942
02:07:38,629 --> 02:07:36,560
itself safe and ready to get lifted up

2943
02:07:40,709 --> 02:07:38,639
out of the recovery vessel the goad

2944
02:07:43,109 --> 02:07:40,719
navigator has left the port at this

2945
02:07:46,149 --> 02:07:43,119
point and is currently making its way

2946
02:07:48,229 --> 02:07:46,159
out to that splashdown zone at pensacola

2947
02:07:50,950 --> 02:07:48,239
so it'll be there ready and waiting

2948
02:07:52,950 --> 02:07:50,960
about 40 plus people on board standing

2949
02:07:54,629 --> 02:07:52,960
by to help bring dragon onto the boat

2950
02:07:56,790 --> 02:07:54,639
itself and get the crew out of the

2951
02:07:59,270 --> 02:07:56,800
capsule yeah

2952
02:08:01,750 --> 02:07:59,280
it's an exciting day like i said we're

2953
02:08:04,629 --> 02:08:01,760
about four and a half hours away from

2954
02:08:06,229 --> 02:08:04,639
those events that that's the orbit burn

2955
02:08:07,350 --> 02:08:06,239
from occurring so we have a little bit

2956
02:08:08,950 --> 02:08:07,360
of time

2957
02:08:29,189 --> 02:08:08,960
we will continue

2958
02:08:29,199 --> 02:08:32,310
go ahead spacex

2959
02:08:36,629 --> 02:08:34,950
okay uh in preparation for entry uh

2960
02:08:38,950 --> 02:08:36,639
we'll be commanding the

2961
02:08:40,790 --> 02:08:38,960
heat exchanger bypass close so this will

2962
02:08:42,229 --> 02:08:40,800
mean that manual control of cabin

2963
02:08:48,950 --> 02:08:42,239
temperature will be disallowed that

2964
02:08:53,910 --> 02:08:51,430
okay copy that thanks mike

2965
02:08:57,430 --> 02:08:53,920
no problem in addition we do not expect

2966
02:09:02,470 --> 02:08:57,440
to need to elevate the loop speed for uh

2967
02:09:02,480 --> 02:09:17,430
okay copy that thank you

2968
02:09:21,350 --> 02:09:19,510
and so right there they're just doing a

2969
02:09:22,950 --> 02:09:21,360
couple of housekeeping steps as again

2970
02:09:25,270 --> 02:09:22,960
they're going to be conditioning the

2971
02:09:27,910 --> 02:09:25,280
inside of the cabin and doug and bob's

2972
02:09:29,589 --> 02:09:27,920
suits for that actual reentry they're

2973
02:09:30,629 --> 02:09:29,599
going to be cooling down the inside of

2974
02:09:33,030 --> 02:09:30,639
the cabin

2975
02:09:34,870 --> 02:09:33,040
and doing what's known as a suit purge

2976
02:09:36,069 --> 02:09:34,880
so once bob and doug are suited up and

2977
02:09:37,189 --> 02:09:36,079
in their seats

2978
02:09:39,750 --> 02:09:37,199
they'll do

2979
02:09:42,229 --> 02:09:39,760
basically a flush with very or

2980
02:09:44,470 --> 02:09:42,239
with cooler air with cooler nitrox

2981
02:09:46,629 --> 02:09:44,480
flowing into their suits they're not

2982
02:09:48,229 --> 02:09:46,639
pressurized while they're suited up

2983
02:09:49,189 --> 02:09:48,239
they'll just leave a zipper open a

2984
02:09:52,229 --> 02:09:49,199
little bit

2985
02:09:54,550 --> 02:09:52,239
they will do suit leak checks

2986
02:09:56,950 --> 02:09:54,560
which will see them pressurize the suits

2987
02:09:58,870 --> 02:09:56,960
completely as again those suits designed

2988
02:10:01,030 --> 02:09:58,880
to protect them in the event of a cabin

2989
02:10:01,910 --> 02:10:01,040
depressurization

2990
02:10:03,510 --> 02:10:01,920
any

2991
02:10:05,750 --> 02:10:03,520
contaminants in the atmosphere things

2992
02:10:08,629 --> 02:10:05,760
like that but they will be wearing them

2993
02:10:11,750 --> 02:10:08,639
for this dynamic phase which i know we

2994
02:10:13,589 --> 02:10:11,760
have a question here from nick who

2995
02:10:15,589 --> 02:10:13,599
had wanted to know did the seats recline

2996
02:10:17,830 --> 02:10:15,599
to allow them to lie flat during sleep

2997
02:10:19,510 --> 02:10:17,840
or do they sleep upright

2998
02:10:21,270 --> 02:10:19,520
the suits and the seats kind of an

2999
02:10:23,109 --> 02:10:21,280
integrated system

3000
02:10:25,109 --> 02:10:23,119
the the seats themselves as kate

3001
02:10:27,830 --> 02:10:25,119
described a little bit earlier

3002
02:10:30,390 --> 02:10:27,840
are rigid carbon fiber so the seats do

3003
02:10:31,350 --> 02:10:30,400
move as we saw on launch day where

3004
02:10:32,550 --> 02:10:31,360
they're

3005
02:10:33,430 --> 02:10:32,560
able to

3006
02:10:35,669 --> 02:10:33,440
both

3007
02:10:37,910 --> 02:10:35,679
recline and decline but

3008
02:10:40,470 --> 02:10:37,920
the seats themselves don't move and

3009
02:10:42,629 --> 02:10:40,480
really when you're in outer space

3010
02:10:44,790 --> 02:10:42,639
you can't get the sensation of laying

3011
02:10:45,990 --> 02:10:44,800
down so the seats reclining don't really

3012
02:10:49,109 --> 02:10:46,000
do much for you when you're in

3013
02:10:51,750 --> 02:10:49,119
microgravity uh pretty much any surface

3014
02:10:53,990 --> 02:10:51,760
on the dragon spacecraft will serve as a

3015
02:10:55,589 --> 02:10:54,000
bed um the same thing kind of true

3016
02:10:57,669 --> 02:10:55,599
onboard the international space station

3017
02:10:59,830 --> 02:10:57,679
where if we have more crew members than

3018
02:11:01,430 --> 02:10:59,840
we have crew accommodations at times

3019
02:11:03,830 --> 02:11:01,440
crew members can just camp out and if

3020
02:11:05,910 --> 02:11:03,840
you've ever seen any of the photos from

3021
02:11:07,910 --> 02:11:05,920
back in the shuttle days when we would

3022
02:11:09,189 --> 02:11:07,920
have seven people in a relatively small

3023
02:11:11,350 --> 02:11:09,199
enclosure

3024
02:11:13,510 --> 02:11:11,360
you can just essentially

3025
02:11:15,910 --> 02:11:13,520
strap your sleeping bag to the wall and

3026
02:11:18,229 --> 02:11:15,920
that's your bed for the evening yeah so

3027
02:11:20,229 --> 02:11:18,239
essentially in space your body doesn't

3028
02:11:22,950 --> 02:11:20,239
really have a reference to determine

3029
02:11:25,510 --> 02:11:22,960
what is up and what is down aside from

3030
02:11:27,589 --> 02:11:25,520
you know what you can determine visually

3031
02:11:30,310 --> 02:11:27,599
so in the case of whenever they're

3032
02:11:33,189 --> 02:11:30,320
sleeping their their body can't really

3033
02:11:35,430 --> 02:11:33,199
feel laying down they just feel being in

3034
02:11:37,189 --> 02:11:35,440
their seat so while like dan said the

3035
02:11:38,790 --> 02:11:37,199
seats do

3036
02:11:41,830 --> 02:11:38,800
actuate so that they're in launch

3037
02:11:44,390 --> 02:11:41,840
position or landing position where the

3038
02:11:46,310 --> 02:11:44,400
entire seat is basically moving 40

3039
02:11:48,870 --> 02:11:46,320
degrees this way or that way they don't

3040
02:11:51,030 --> 02:11:48,880
necessarily recline out like a recliner

3041
02:11:53,589 --> 02:11:51,040
chair would so although i'm sure that

3042
02:11:55,669 --> 02:11:53,599
would also be very comfortable

3043
02:11:59,430 --> 02:11:55,679
our next question coming to us again

3044
02:12:01,589 --> 02:11:59,440
from twitter using the hashtag ask nasa

3045
02:12:03,109 --> 02:12:01,599
can you talk about the recovery ship

3046
02:12:04,870 --> 02:12:03,119
absolutely rose

3047
02:12:06,790 --> 02:12:04,880
like i mentioned before

3048
02:12:08,709 --> 02:12:06,800
you know this is the second opportunity

3049
02:12:11,669 --> 02:12:08,719
that we've had to highlight the recovery

3050
02:12:14,790 --> 02:12:11,679
team given the fact that our water

3051
02:12:17,669 --> 02:12:14,800
landings and needing to retrieve a crew

3052
02:12:19,350 --> 02:12:17,679
is very new to our company here uh we're

3053
02:12:21,189 --> 02:12:19,360
very excited to be able to highlight

3054
02:12:22,390 --> 02:12:21,199
that team now for the second time on our

3055
02:12:24,470 --> 02:12:22,400
webcast

3056
02:12:27,030 --> 02:12:24,480
the recovery team

3057
02:12:29,750 --> 02:12:27,040
the recovery ship is there are actually

3058
02:12:31,990 --> 02:12:29,760
two of them we have one that is capable

3059
02:12:33,589 --> 02:12:32,000
of assisting recoveries on the west

3060
02:12:35,430 --> 02:12:33,599
coast of florida and that's the go

3061
02:12:37,589 --> 02:12:35,440
navigator that's what we'll be using for

3062
02:12:39,589 --> 02:12:37,599
today's recovery there's also the go

3063
02:12:40,629 --> 02:12:39,599
searcher which is located on the east

3064
02:12:45,750 --> 02:12:40,639
coast

3065
02:12:48,149 --> 02:12:45,760
identical and they are able to be

3066
02:12:50,229 --> 02:12:48,159
staffed fully staffed not only for

3067
02:12:52,470 --> 02:12:50,239
recovery operations but

3068
02:12:54,709 --> 02:12:52,480
for medical as well

3069
02:12:55,660 --> 02:12:54,719
we're putting the grab sample container

3070
02:12:58,550 --> 02:12:55,670
collection and work

3071
02:13:01,430 --> 02:12:58,560
[Applause]

3072
02:13:07,189 --> 02:13:01,440
okay spacex copies grab sample container

3073
02:13:16,790 --> 02:13:09,750
and that right there though occasionally

3074
02:13:26,390 --> 02:13:19,830
okay spacex copy serial number two zero

3075
02:13:30,950 --> 02:13:28,310
that exchange right there real quick the

3076
02:13:32,390 --> 02:13:30,960
the crew members onboard dragon

3077
02:13:34,550 --> 02:13:32,400
something they do on board the station

3078
02:13:36,629 --> 02:13:34,560
as well take occasional air samples you

3079
02:13:38,629 --> 02:13:36,639
heard them called the grab sample

3080
02:13:40,470 --> 02:13:38,639
where they're basically taking these

3081
02:13:42,149 --> 02:13:40,480
samples and sealing them up and then

3082
02:13:43,750 --> 02:13:42,159
they just get assessed back down on the

3083
02:13:45,750 --> 02:13:43,760
ground you're just constantly looking

3084
02:13:47,189 --> 02:13:45,760
for what kind of atmosphere your crew

3085
02:13:48,950 --> 02:13:47,199
members are in

3086
02:13:51,430 --> 02:13:48,960
as when you're in a spacecraft it's an

3087
02:13:53,030 --> 02:13:51,440
enclosed environment so you have to

3088
02:13:54,550 --> 02:13:53,040
worry about everything that gets put

3089
02:13:55,669 --> 02:13:54,560
into that atmosphere

3090
02:13:58,069 --> 02:13:55,679
stays there

3091
02:14:00,709 --> 02:13:58,079
so things like carbon dioxide

3092
02:14:03,510 --> 02:14:00,719
carbon monoxide any other contaminants

3093
02:14:05,109 --> 02:14:03,520
can build up in an enclosed space

3094
02:14:07,030 --> 02:14:05,119
eventually become hazardous so we have

3095
02:14:08,950 --> 02:14:07,040
to have a lot of systems to help

3096
02:14:10,470 --> 02:14:08,960
constantly scrub or clean those things

3097
02:14:12,149 --> 02:14:10,480
out from the atmosphere and we'll do

3098
02:14:13,589 --> 02:14:12,159
these grab samples just to make sure

3099
02:14:15,350 --> 02:14:13,599
that they're they're basically doing

3100
02:14:17,189 --> 02:14:15,360
their job yeah

3101
02:14:19,910 --> 02:14:17,199
going back to rose's question coming to

3102
02:14:22,069 --> 02:14:19,920
us from twitter using the hashtag ask

3103
02:14:24,629 --> 02:14:22,079
nasa asking us to talk about the

3104
02:14:28,149 --> 02:14:24,639
recovery ship uh yes so we have two

3105
02:14:30,709 --> 02:14:28,159
identical recovery ships or vessels um

3106
02:14:34,229 --> 02:14:30,719
specifically to our recovery today we

3107
02:14:36,550 --> 02:14:34,239
are utilizing go navigator for our golf

3108
02:14:37,830 --> 02:14:36,560
excuse me for our landing in the gulf of

3109
02:14:40,709 --> 02:14:37,840
mexico

3110
02:14:43,109 --> 02:14:40,719
in addition to the recovery ship itself

3111
02:14:44,950 --> 02:14:43,119
there are also two fast boots so those

3112
02:14:47,430 --> 02:14:44,960
will be transported

3113
02:14:49,589 --> 02:14:47,440
to the general location about three

3114
02:14:51,189 --> 02:14:49,599
nautical miles away from the landing

3115
02:14:53,189 --> 02:14:51,199
site itself

3116
02:14:54,790 --> 02:14:53,199
those fast boats will be deployed from

3117
02:14:56,950 --> 02:14:54,800
the vessel and

3118
02:14:58,790 --> 02:14:56,960
they will make their way very quickly to

3119
02:15:00,629 --> 02:14:58,800
the castle itself

3120
02:15:03,830 --> 02:15:00,639
they'll wait a couple hundred feet away

3121
02:15:06,229 --> 02:15:03,840
from the capsule as the initial sniffing

3122
02:15:08,550 --> 02:15:06,239
tests are done those sniffing tests are

3123
02:15:11,750 --> 02:15:08,560
intended to determine whether or not any

3124
02:15:14,470 --> 02:15:11,760
toxic vapors from the hypergolic

3125
02:15:15,910 --> 02:15:14,480
fuels on board hypergols are essentially

3126
02:15:17,750 --> 02:15:15,920
propellants that

3127
02:15:19,990 --> 02:15:17,760
whenever you

3128
02:15:23,430 --> 02:15:20,000
put them in contact with each other they

3129
02:15:25,510 --> 02:15:23,440
they ignite so it is an ideal uh

3130
02:15:27,270 --> 02:15:25,520
propellant used in space because you

3131
02:15:29,750 --> 02:15:27,280
don't need an ignition source you just

3132
02:15:30,950 --> 02:15:29,760
combine the two and you have your

3133
02:15:32,149 --> 02:15:30,960
reaction

3134
02:15:36,470 --> 02:15:32,159
so

3135
02:15:38,390 --> 02:15:36,480
team will make sure that there aren't

3136
02:15:40,149 --> 02:15:38,400
any of those floating around and make

3137
02:15:42,149 --> 02:15:40,159
sure that it is safe to approach once

3138
02:15:43,830 --> 02:15:42,159
they get that go for approach they'll

3139
02:15:45,350 --> 02:15:43,840
head over to the capsule

3140
02:15:46,950 --> 02:15:45,360
and essentially

3141
02:15:48,310 --> 02:15:46,960
someone that i'm really excited to see

3142
02:15:50,470 --> 02:15:48,320
in action today

3143
02:15:52,790 --> 02:15:50,480
will cover will actually climb up on top

3144
02:15:55,830 --> 02:15:52,800
of the capsule and attach the rigging

3145
02:15:57,910 --> 02:15:55,840
equipment necessary to hoist the dragon

3146
02:16:01,109 --> 02:15:57,920
out of the water and onto the recovery

3147
02:16:03,669 --> 02:16:01,119
vessel so um all and to me that should

3148
02:16:05,589 --> 02:16:03,679
take about 30 35 minutes

3149
02:16:07,350 --> 02:16:05,599
and at that point the recovery vessel

3150
02:16:09,510 --> 02:16:07,360
will be in place they'll be able to hook

3151
02:16:12,149 --> 02:16:09,520
everything up use the

3152
02:16:13,830 --> 02:16:12,159
hydraulic crane to lift the capsule out

3153
02:16:15,910 --> 02:16:13,840
of the water and onto the recovery

3154
02:16:18,629 --> 02:16:15,920
vessel get it settled comfortably

3155
02:16:21,030 --> 02:16:18,639
in the nest and at that point we'll open

3156
02:16:23,189 --> 02:16:21,040
up the hatch and say hi to bob and doug

3157
02:16:25,830 --> 02:16:23,199
yeah and they'll almost immediately move

3158
02:16:27,750 --> 02:16:25,840
into medical quarters on board the ship

3159
02:16:30,229 --> 02:16:27,760
because it has pretty much everything

3160
02:16:32,790 --> 02:16:30,239
you need to outfit and sustain a crew of

3161
02:16:34,790 --> 02:16:32,800
a little over 40 people and then

3162
02:16:36,549 --> 02:16:34,800
immediately over the dragon capsule is

3163
02:16:38,709 --> 02:16:36,559
the helidek where they'll be landing a

3164
02:16:40,150 --> 02:16:38,719
helicopter following recovery today

3165
02:16:43,030 --> 02:16:40,160
which is what's going to actually bring

3166
02:16:45,509 --> 02:16:43,040
bob and doug back to shore

3167
02:16:46,870 --> 02:16:45,519
next up our question comes from spinach

3168
02:16:49,830 --> 02:16:46,880
who wants to know why do you need a heat

3169
02:16:51,750 --> 02:16:49,840
shield on entry but not on ascent speed

3170
02:16:54,070 --> 02:16:51,760
relative to atmosphere must be roughly

3171
02:16:56,950 --> 02:16:54,080
equal in both cases

3172
02:16:57,830 --> 02:16:56,960
yeah so that is a really good question

3173
02:16:59,429 --> 02:16:57,840
the

3174
02:17:02,070 --> 02:16:59,439
short answer is it's all about

3175
02:17:03,990 --> 02:17:02,080
directionality so whenever we are

3176
02:17:06,709 --> 02:17:04,000
launching the dragon capsule

3177
02:17:08,950 --> 02:17:06,719
it's pointing upwards and it is heading

3178
02:17:11,190 --> 02:17:08,960
towards the international space station

3179
02:17:13,669 --> 02:17:11,200
so the heat shield or rather the bother

3180
02:17:17,030 --> 02:17:13,679
the bottom of the capsule is not exposed

3181
02:17:20,309 --> 02:17:17,040
and is not encountering any thermal

3182
02:17:22,549 --> 02:17:20,319
any thermal differences or temperatures

3183
02:17:24,950 --> 02:17:22,559
during that ascent phase also it's

3184
02:17:27,589 --> 02:17:24,960
important to note that

3185
02:17:29,349 --> 02:17:27,599
while the capsule is actually going

3186
02:17:30,389 --> 02:17:29,359
through the earth's atmosphere which is

3187
02:17:32,309 --> 02:17:30,399
where

3188
02:17:33,830 --> 02:17:32,319
you have atmosphere and therefore

3189
02:17:37,030 --> 02:17:33,840
friction as you're moving through the

3190
02:17:39,910 --> 02:17:37,040
atmosphere and that's what causes the

3191
02:17:43,349 --> 02:17:39,920
the charring as we see uh upon re-entry

3192
02:17:45,270 --> 02:17:43,359
the amount of friction that the capsule

3193
02:17:47,030 --> 02:17:45,280
is experiencing as it is leaving the

3194
02:17:47,990 --> 02:17:47,040
atmosphere to go the international space

3195
02:17:50,709 --> 02:17:48,000
station

3196
02:17:53,190 --> 02:17:50,719
is a fraction of what it will encounter

3197
02:17:55,910 --> 02:17:53,200
as it is re-entering also to note the

3198
02:17:57,990 --> 02:17:55,920
shape of the dragon capsule is more

3199
02:17:59,910 --> 02:17:58,000
aerodynamic at the top

3200
02:18:02,950 --> 02:17:59,920
so again allowing it to cut through the

3201
02:18:05,349 --> 02:18:02,960
atmosphere with minimal friction

3202
02:18:07,669 --> 02:18:05,359
so after the capsule detaches and as we

3203
02:18:09,910 --> 02:18:07,679
will see today comes back down that flat

3204
02:18:12,469 --> 02:18:09,920
end is designed to encounter the

3205
02:18:14,870 --> 02:18:12,479
atmosphere and slow it down so it's kind

3206
02:18:17,509 --> 02:18:14,880
of by intention the opposite effect we

3207
02:18:18,549 --> 02:18:17,519
use the atmosphere to help slow us down

3208
02:18:20,709 --> 02:18:18,559
safely

3209
02:18:22,870 --> 02:18:20,719
as opposed to wanting to escape earth's

3210
02:18:24,309 --> 02:18:22,880
gravity as efficiently as possible so we

3211
02:18:25,910 --> 02:18:24,319
want to cut through it as much as

3212
02:18:27,910 --> 02:18:25,920
possible

3213
02:18:29,429 --> 02:18:27,920
all right next up is a question from

3214
02:18:31,750 --> 02:18:29,439
casey wants to know what will the crew

3215
02:18:33,190 --> 02:18:31,760
be able to see out of the window upon

3216
02:18:34,870 --> 02:18:33,200
reentry

3217
02:18:36,950 --> 02:18:34,880
i think it was bob who actually answered

3218
02:18:39,990 --> 02:18:36,960
this a little bit earlier this week

3219
02:18:41,990 --> 02:18:40,000
where he recalled what he saw during his

3220
02:18:43,589 --> 02:18:42,000
re-entries on the space shuttle where

3221
02:18:46,070 --> 02:18:43,599
when astronauts look out the window they

3222
02:18:47,589 --> 02:18:46,080
can see the ablative material of the

3223
02:18:48,790 --> 02:18:47,599
heat shield so the heat shield is

3224
02:18:51,349 --> 02:18:48,800
designed

3225
02:18:53,509 --> 02:18:51,359
so as parts really start to heat up they

3226
02:18:55,830 --> 02:18:53,519
actually kind of peel off and that helps

3227
02:18:58,230 --> 02:18:55,840
dissipate the heat or the most intense

3228
02:19:00,549 --> 02:18:58,240
part of the heat during re-entry and for

3229
02:19:02,549 --> 02:19:00,559
a crew member it looks like just red

3230
02:19:03,910 --> 02:19:02,559
bits of glowing material flying past

3231
02:19:06,150 --> 02:19:03,920
your window

3232
02:19:08,950 --> 02:19:06,160
and for them in particular though there

3233
02:19:11,509 --> 02:19:08,960
will be uh plasma building up around the

3234
02:19:13,990 --> 02:19:11,519
spacecraft as it heats up to about 3 500

3235
02:19:15,190 --> 02:19:14,000
degrees fahrenheit and so out their

3236
02:19:17,270 --> 02:19:15,200
window they'll be able to see

3237
02:19:19,030 --> 02:19:17,280
essentially some really bright orange

3238
02:19:20,469 --> 02:19:19,040
not quite flames

3239
02:19:23,509 --> 02:19:20,479
but definitely something that looks

3240
02:19:25,190 --> 02:19:23,519
energetic and that'll be

3241
02:19:27,270 --> 02:19:25,200
their main view out of the window which

3242
02:19:30,629 --> 02:19:27,280
they'll have those windows open

3243
02:19:32,950 --> 02:19:30,639
and uncovered during the reentry

3244
02:19:34,790 --> 02:19:32,960
our next question comes from jeff who

3245
02:19:36,629 --> 02:19:34,800
wants to know what's the longest someone

3246
02:19:38,709 --> 02:19:36,639
has been in space

3247
02:19:40,950 --> 02:19:38,719
i know the cumulative record holder

3248
02:19:42,709 --> 02:19:40,960
right now is a russian cosmonaut gennady

3249
02:19:45,589 --> 02:19:42,719
padalka he's got

3250
02:19:48,790 --> 02:19:45,599
a little over 800 days

3251
02:19:50,389 --> 02:19:48,800
in space he's been a long-duration crew

3252
02:19:52,710 --> 02:19:50,399
member not only on the international

3253
02:19:55,190 --> 02:19:52,720
space station but also previously on the

3254
02:19:57,670 --> 02:19:55,200
russian mir space station which was

3255
02:19:59,830 --> 02:19:57,680
really kind of the harbinger of long

3256
02:20:01,590 --> 02:19:59,840
duration space flight where you had

3257
02:20:05,429 --> 02:20:01,600
people up there living for months and

3258
02:20:10,630 --> 02:20:07,910
i believe the current record holder is

3259
02:20:12,630 --> 02:20:10,640
it still peggy woodson

3260
02:20:16,230 --> 02:20:12,640
peggy whitson is the american record

3261
02:20:20,309 --> 02:20:18,630
all right our next question comes from

3262
02:20:22,469 --> 02:20:20,319
timothy who wants to know is this the

3263
02:20:23,750 --> 02:20:22,479
first splashdown since the apollo

3264
02:20:26,150 --> 02:20:23,760
missions

3265
02:20:28,230 --> 02:20:26,160
yes it is this is the first u.s flash

3266
02:20:30,630 --> 02:20:28,240
down since the apollo missions there is

3267
02:20:33,030 --> 02:20:30,640
one russian soyuz i'd have to go back

3268
02:20:35,190 --> 02:20:33,040
and look up exactly which mission it was

3269
02:20:38,230 --> 02:20:35,200
but it technically did land in a frozen

3270
02:20:40,230 --> 02:20:38,240
lake so it was a splashdown although

3271
02:20:41,910 --> 02:20:40,240
unintentional this is the first time

3272
02:20:44,070 --> 02:20:41,920
we've splashed down american crew

3273
02:20:45,590 --> 02:20:44,080
members or at the very least this is the

3274
02:20:47,030 --> 02:20:45,600
first time we've done an ocean-based

3275
02:20:49,429 --> 02:20:47,040
splashdown

3276
02:20:54,309 --> 02:20:49,439
since apollo the last one being apollo

3277
02:20:59,510 --> 02:20:56,830
our next question coming to us from

3278
02:21:02,230 --> 02:20:59,520
krishna what wind speed does it take for

3279
02:21:05,349 --> 02:21:02,240
the splashdown to get scrubbed

3280
02:21:07,670 --> 02:21:05,359
ooh that is a really good question

3281
02:21:10,070 --> 02:21:07,680
i can't recall exactly what it is off

3282
02:21:12,630 --> 02:21:10,080
the top of my head but i think it is no

3283
02:21:14,630 --> 02:21:12,640
more than 15 miles per hour i might be

3284
02:21:17,030 --> 02:21:14,640
recalling it differently it was about 15

3285
02:21:19,190 --> 02:21:17,040
feet per second which is about 10 miles

3286
02:21:21,990 --> 02:21:19,200
an hour was the range that we were

3287
02:21:24,230 --> 02:21:22,000
looking to be under uh for this mission

3288
02:21:26,309 --> 02:21:24,240
which today we've said a couple of times

3289
02:21:28,950 --> 02:21:26,319
the weather ended up being almost

3290
02:21:31,190 --> 02:21:28,960
perfect for the splashdown we have winds

3291
02:21:33,830 --> 02:21:31,200
in the splashline area of only about a

3292
02:21:36,870 --> 02:21:33,840
mile and a half per second

3293
02:21:38,710 --> 02:21:36,880
so very gentle winds there today

3294
02:21:41,030 --> 02:21:38,720
but for this particular mission our

3295
02:21:44,070 --> 02:21:41,040
constraint was about 15 feet per second

3296
02:21:45,670 --> 02:21:44,080
which is about 10 miles an hour

3297
02:21:48,309 --> 02:21:45,680
our next question coming to us from

3298
02:21:50,150 --> 02:21:48,319
danny again this is using the hashtag

3299
02:21:51,910 --> 02:21:50,160
asknasa on twitter keep your questions

3300
02:21:53,910 --> 02:21:51,920
coming

3301
02:21:55,670 --> 02:21:53,920
question is great stream guys learning

3302
02:21:56,790 --> 02:21:55,680
so much oh awesome glad to hear thanks

3303
02:21:58,790 --> 02:21:56,800
for the feedback

3304
02:22:01,110 --> 02:21:58,800
would it be possible for the spacex

3305
02:22:03,670 --> 02:22:01,120
capsule capsule to be used again in

3306
02:22:05,750 --> 02:22:03,680
future missions as it is or would it

3307
02:22:07,349 --> 02:22:05,760
need a complete overhaul before heading

3308
02:22:09,349 --> 02:22:07,359
back up

3309
02:22:10,550 --> 02:22:09,359
question so uh we

3310
02:22:13,270 --> 02:22:10,560
absolutely

3311
02:22:15,429 --> 02:22:13,280
have been aiming to use to reuse dragon

3312
02:22:17,990 --> 02:22:15,439
capsules from the very beginning

3313
02:22:20,710 --> 02:22:18,000
initially when we started reusing our

3314
02:22:22,870 --> 02:22:20,720
dragon cargo capsules

3315
02:22:24,710 --> 02:22:22,880
figuring out how to waterproof it was

3316
02:22:27,030 --> 02:22:24,720
quite the challenge and once we figured

3317
02:22:29,990 --> 02:22:27,040
that out we were actually able to reduce

3318
02:22:32,790 --> 02:22:30,000
the amount of overhaul or refurbishment

3319
02:22:34,950 --> 02:22:32,800
required between usage of the capsules

3320
02:22:38,070 --> 02:22:34,960
so that being said

3321
02:22:40,790 --> 02:22:38,080
things like the heat shield and the

3322
02:22:43,030 --> 02:22:40,800
tps or thermal protective system panels

3323
02:22:44,950 --> 02:22:43,040
on the exterior of the capsule those

3324
02:22:47,750 --> 02:22:44,960
things generally as of right now would

3325
02:22:50,630 --> 02:22:47,760
not be reused but the guts and the

3326
02:22:52,950 --> 02:22:50,640
brains of the capsule most definitely uh

3327
02:22:55,830 --> 02:22:52,960
we aim to and of course this is this

3328
02:22:57,270 --> 02:22:55,840
prog this this process transforms over

3329
02:22:59,590 --> 02:22:57,280
time the more that we do it we

3330
02:23:01,670 --> 02:22:59,600
understand more we learn more from data

3331
02:23:05,030 --> 02:23:01,680
and tests and we're able to make the

3332
02:23:07,110 --> 02:23:05,040
process more efficient and so eventually

3333
02:23:09,830 --> 02:23:07,120
we will hopefully be able to get to

3334
02:23:11,670 --> 02:23:09,840
absolutely no refurbishment required in

3335
02:23:13,270 --> 02:23:11,680
order to reuse a capsule

3336
02:23:15,190 --> 02:23:13,280
all right our next question comes from

3337
02:23:17,030 --> 02:23:15,200
texas dog mom wants to know why is it

3338
02:23:19,910 --> 02:23:17,040
important to know exactly what food and

3339
02:23:21,590 --> 02:23:19,920
water is consumed during re-entry it's a

3340
02:23:23,910 --> 02:23:21,600
good question

3341
02:23:26,389 --> 02:23:23,920
and it really comes down to

3342
02:23:28,710 --> 02:23:26,399
we have a very set amount of food and

3343
02:23:30,309 --> 02:23:28,720
again dragon not the biggest space so

3344
02:23:33,190 --> 02:23:30,319
it's probably hard to lose something on

3345
02:23:35,830 --> 02:23:33,200
dragon but we do meticulously track

3346
02:23:38,389 --> 02:23:35,840
everything in microgravity just so if we

3347
02:23:40,389 --> 02:23:38,399
are in a situation because remember

3348
02:23:42,710 --> 02:23:40,399
today was the primary landing

3349
02:23:44,550 --> 02:23:42,720
opportunity for bob and doug if for some

3350
02:23:47,750 --> 02:23:44,560
reason we had to wave off they would

3351
02:23:49,990 --> 02:23:47,760
still be in space for another 48 hours

3352
02:23:52,550 --> 02:23:50,000
and so we're always just tracking where

3353
02:23:54,309 --> 02:23:52,560
everything is inside that capsule

3354
02:23:56,230 --> 02:23:54,319
for the mission not only so it's easy to

3355
02:23:58,630 --> 02:23:56,240
find but at the end of the mission if we

3356
02:24:00,950 --> 02:23:58,640
find something is missing you have to go

3357
02:24:03,270 --> 02:24:00,960
and find it that's something

3358
02:24:04,710 --> 02:24:03,280
if you think to how aircraft factories

3359
02:24:06,550 --> 02:24:04,720
operate

3360
02:24:09,349 --> 02:24:06,560
anything that gets brought into the area

3361
02:24:11,030 --> 02:24:09,359
has to be tracked because if it's not

3362
02:24:12,950 --> 02:24:11,040
if something is found and it hasn't been

3363
02:24:14,710 --> 02:24:12,960
tracked previously or if you know you

3364
02:24:15,830 --> 02:24:14,720
brought something in and you can't find

3365
02:24:17,510 --> 02:24:15,840
it

3366
02:24:19,270 --> 02:24:17,520
you have to generally stop what you're

3367
02:24:20,309 --> 02:24:19,280
doing and go find it

3368
02:24:22,630 --> 02:24:20,319
so

3369
02:24:24,710 --> 02:24:22,640
definitely important to track everything

3370
02:24:26,469 --> 02:24:24,720
on board water and food

3371
02:24:28,230 --> 02:24:26,479
was just the item of the day for them

3372
02:24:29,190 --> 02:24:28,240
this morning as they were in their post

3373
02:24:31,030 --> 02:24:29,200
sleep

3374
02:24:32,710 --> 02:24:31,040
just wrapping up

3375
02:24:37,510 --> 02:24:32,720
getting their breakfast before they

3376
02:24:41,990 --> 02:24:39,750
and there you see a live shot of our

3377
02:24:45,429 --> 02:24:42,000
mission control center here in hawthorne

3378
02:24:48,309 --> 02:24:45,439
california our dragon operators are

3379
02:24:49,830 --> 02:24:48,319
ready to begin our deorbit phase which

3380
02:24:51,750 --> 02:24:49,840
again that won't be happening for a

3381
02:24:55,190 --> 02:24:51,760
couple hours still

3382
02:24:57,910 --> 02:24:55,200
but everyone is in place and ready to

3383
02:25:01,030 --> 02:24:57,920
monitor dragon as we approach the final

3384
02:25:02,550 --> 02:25:01,040
steps of our re-entry phase

3385
02:25:04,710 --> 02:25:02,560
at this point we're going to check in on

3386
02:25:07,429 --> 02:25:04,720
dragon see where it is it looks like

3387
02:25:09,110 --> 02:25:07,439
it's about to go over brazil down there

3388
02:25:12,070 --> 02:25:09,120
in south america

3389
02:29:35,670 --> 02:25:12,080
so enjoy this live view of our ground

3390
02:31:04,710 --> 02:29:38,630
dragon spacex for procedure 4 decimal

3391
02:31:16,150 --> 02:31:07,590
dragon spacex for procedure four decimal

3392
02:31:20,469 --> 02:31:18,150
go ahead mike

3393
02:31:22,389 --> 02:31:20,479
hey doug um just want to clarify uh a

3394
02:31:24,950 --> 02:31:22,399
couple things so per the previous

3395
02:31:26,309 --> 02:31:24,960
mention for section one the no path is

3396
02:31:29,110 --> 02:31:26,319
applicable because we will not be

3397
02:31:30,550 --> 02:31:29,120
elevating loop speeds in addition when

3398
02:31:33,590 --> 02:31:30,560
completing step

3399
02:31:35,510 --> 02:31:33,600
3 decimal 4 please be sure to untether

3400
02:31:42,550 --> 02:31:35,520
and stow the camera caps back in

3401
02:31:46,160 --> 02:31:45,190
okay copy all and then 3.4 you want us

3402
02:31:47,510 --> 02:31:46,170
to uh

3403
02:31:49,830 --> 02:31:47,520
[Music]

3404
02:31:51,270 --> 02:31:49,840
take all the camera caps

3405
02:31:52,710 --> 02:31:51,280
untether them and put them back in

3406
02:31:55,030 --> 02:31:52,720
location eight

3407
02:31:56,630 --> 02:31:55,040
and uh i think our suggestion would be

3408
02:32:00,550 --> 02:31:56,640
that we'll probably just do that now

3409
02:32:02,230 --> 02:32:00,560
unless you guys have a reason not to

3410
02:32:03,830 --> 02:32:02,240
hey we agree with that plan and that's a

3411
02:40:44,230 --> 02:32:03,840
good read back

3412
02:40:48,710 --> 02:40:46,710
all right well we are still following

3413
02:40:50,870 --> 02:40:48,720
along with bob and doug's journey back

3414
02:40:52,870 --> 02:40:50,880
home today everything continuing to

3415
02:40:55,349 --> 02:40:52,880
proceed smoothly with the departure of

3416
02:40:57,190 --> 02:40:55,359
dragon from the space station yesterday

3417
02:40:58,790 --> 02:40:57,200
they have been awake for a couple of

3418
02:41:01,110 --> 02:40:58,800
hours now after getting their eight

3419
02:41:02,790 --> 02:41:01,120
hours of rest onboard the dragon capsule

3420
02:41:04,389 --> 02:41:02,800
and everything's really focused on the

3421
02:41:07,030 --> 02:41:04,399
events coming up in just about three

3422
02:41:09,110 --> 02:41:07,040
hours from now yeah so we have a number

3423
02:41:11,269 --> 02:41:09,120
of things that will be happening um as

3424
02:41:12,630 --> 02:41:11,279
dan said we're actually looking for our

3425
02:41:16,469 --> 02:41:12,640
events to begin

3426
02:41:20,630 --> 02:41:16,479
at in three hours and 42 minutes first

3427
02:41:23,590 --> 02:41:20,640
we will have claw separation so that is

3428
02:41:25,269 --> 02:41:23,600
deactivating or separating the trunk the

3429
02:41:28,790 --> 02:41:25,279
claw is the piece of hardware that

3430
02:41:31,269 --> 02:41:28,800
delivers power and telemetry and fluids

3431
02:41:33,269 --> 02:41:31,279
between the trunk and the dragon capsule

3432
02:41:35,750 --> 02:41:33,279
in order to expose the heat shield in

3433
02:41:37,349 --> 02:41:35,760
preparation for re-entry we will

3434
02:41:39,190 --> 02:41:37,359
jettison the trunk

3435
02:41:41,670 --> 02:41:39,200
it will re-enter the earth's atmosphere

3436
02:41:44,550 --> 02:41:41,680
and disintegrate during that process

3437
02:41:46,870 --> 02:41:44,560
but once we do that where dragon capsule

3438
02:41:50,230 --> 02:41:46,880
will be in its neck it will be in its

3439
02:41:52,870 --> 02:41:50,240
final physical form prior to re-entry uh

3440
02:41:55,510 --> 02:41:52,880
we'll then initiate a deorbit burn it'll

3441
02:41:58,150 --> 02:41:55,520
last about 11 and a half minutes and

3442
02:42:00,389 --> 02:41:58,160
that burn is intended to place dragon on

3443
02:42:01,349 --> 02:42:00,399
its final trajectory for its landing

3444
02:42:03,429 --> 02:42:01,359
site

3445
02:42:06,550 --> 02:42:03,439
which is just off the coast of florida

3446
02:42:09,510 --> 02:42:06,560
near pensacola so once that deorbit burn

3447
02:42:12,469 --> 02:42:09,520
happens uh bob and doug will

3448
02:42:14,389 --> 02:42:12,479
then sit back and continue to monitor

3449
02:42:16,150 --> 02:42:14,399
all the telemetry that and data that

3450
02:42:18,790 --> 02:42:16,160
they have on their screens that's their

3451
02:42:20,710 --> 02:42:18,800
primary mission for today is to just

3452
02:42:22,150 --> 02:42:20,720
keep a tab on things

3453
02:42:24,550 --> 02:42:22,160
there you can see on your screen that

3454
02:42:26,710 --> 02:42:24,560
they're there now not in their suits yet

3455
02:42:29,110 --> 02:42:26,720
we'll wait a little bit longer before

3456
02:42:31,269 --> 02:42:29,120
they have to don their suits but they're

3457
02:42:34,550 --> 02:42:31,279
there doing some checkouts and moving

3458
02:42:37,190 --> 02:42:34,560
about the interior of crew dragon

3459
02:42:40,630 --> 02:42:37,200
like i said that we will perform that

3460
02:42:43,110 --> 02:42:40,640
de-orbit burn lining up the capsule for

3461
02:42:46,070 --> 02:42:43,120
that final re-entry and

3462
02:42:47,030 --> 02:42:46,080
and splashdown off the coast of florida

3463
02:42:49,349 --> 02:42:47,040
and

3464
02:42:51,349 --> 02:42:49,359
after we do the orbit burn we'll close

3465
02:42:53,349 --> 02:42:51,359
that nose cone so the deorbit burn will

3466
02:42:56,550 --> 02:42:53,359
utilize the four

3467
02:42:58,469 --> 02:42:56,560
forward bulkhead draco thrusters

3468
02:42:59,110 --> 02:42:58,479
we will not need to use them and we want

3469
02:43:00,630 --> 02:42:59,120
to

3470
02:43:02,469 --> 02:43:00,640
for the remainder of the mission and we

3471
02:43:04,150 --> 02:43:02,479
want to protect that

3472
02:43:06,389 --> 02:43:04,160
forward hatch there

3473
02:43:08,550 --> 02:43:06,399
that's the hatch that is used for

3474
02:43:11,110 --> 02:43:08,560
ingress and egress or entering and

3475
02:43:13,269 --> 02:43:11,120
exiting the space station and as these

3476
02:43:14,950 --> 02:43:13,279
capsules are designed to be reusable we

3477
02:43:18,389 --> 02:43:14,960
definitely want to protect that hatch so

3478
02:43:21,910 --> 02:43:18,399
we close and lock that nose cone

3479
02:43:24,230 --> 02:43:21,920
and then after the nose cone is in place

3480
02:43:26,550 --> 02:43:24,240
and we confirm that it is locked up we

3481
02:43:28,710 --> 02:43:26,560
then maneuver to that deorbit burn

3482
02:43:30,309 --> 02:43:28,720
attitude uh and

3483
02:43:32,469 --> 02:43:30,319
or excuse me uh

3484
02:43:34,070 --> 02:43:32,479
there let me rephrase that we already

3485
02:43:36,950 --> 02:43:34,080
performed the deorbit burn the nose cone

3486
02:43:38,710 --> 02:43:36,960
will close and we will then

3487
02:43:40,790 --> 02:43:38,720
begin the process of re-entering the

3488
02:43:43,030 --> 02:43:40,800
earth's atmosphere yeah that was pretty

3489
02:43:45,349 --> 02:43:43,040
cool we just saw bob uh

3490
02:43:46,389 --> 02:43:45,359
kind of restowing his spacesuit they

3491
02:43:47,750 --> 02:43:46,399
keep

3492
02:43:49,750 --> 02:43:47,760
their spacesuits at least for this

3493
02:43:51,429 --> 02:43:49,760
mission and the seats on either side of

3494
02:43:53,110 --> 02:43:51,439
them as bob and duggar right there in

3495
02:43:54,469 --> 02:43:53,120
the middle of the commander and the

3496
02:43:56,870 --> 02:43:54,479
pilot seat

3497
02:43:58,309 --> 02:43:56,880
but after they're able to successfully

3498
02:44:00,230 --> 02:43:58,319
re-enter the earth's atmosphere we'll

3499
02:44:03,590 --> 02:44:00,240
get out of that coms blackout and we'll

3500
02:44:05,349 --> 02:44:03,600
get to the actual parachute deploys

3501
02:44:06,950 --> 02:44:05,359
so first we'll have two drogue shoots

3502
02:44:09,429 --> 02:44:06,960
come out those will do the initial

3503
02:44:11,190 --> 02:44:09,439
slowing and stabilization of the vehicle

3504
02:44:13,510 --> 02:44:11,200
followed shortly after by the four main

3505
02:44:16,950 --> 02:44:13,520
parachutes which are scheduled to deploy

3506
02:44:19,269 --> 02:44:16,960
right around 11 45 a.m pacific all that

3507
02:44:21,910 --> 02:44:19,279
sets us up for splash down in the gulf

3508
02:44:24,710 --> 02:44:21,920
of mexico off the coast of florida just

3509
02:44:27,269 --> 02:44:24,720
a few miles away from pensacola that's

3510
02:44:28,590 --> 02:44:27,279
flash down time targeted for 11 48 a.m

3511
02:44:32,630 --> 02:44:28,600
pacific

3512
02:44:34,550 --> 02:44:32,640
1848 gmt or universal time

3513
02:44:37,110 --> 02:44:34,560
there to meet them is going to be the

3514
02:44:40,150 --> 02:44:37,120
crew of the go navigator which has left

3515
02:44:42,710 --> 02:44:40,160
its port these actually some live views

3516
02:44:45,429 --> 02:44:42,720
from the boat itself as it continues to

3517
02:44:47,990 --> 02:44:45,439
make its way out to the recovery zone it

3518
02:44:51,670 --> 02:44:48,000
was able to leave the port right around

3519
02:44:53,190 --> 02:44:51,680
9 20 a.m eastern time this morning as we

3520
02:44:55,110 --> 02:44:53,200
talked about a little bit earlier they

3521
02:44:57,910 --> 02:44:55,120
were tracking an issue with one of the

3522
02:45:00,389 --> 02:44:57,920
backup generators on board the

3523
02:45:02,150 --> 02:45:00,399
go navigator they were working to try

3524
02:45:03,910 --> 02:45:02,160
and get a replacement for that but

3525
02:45:06,230 --> 02:45:03,920
weren't able to get it on board quite in

3526
02:45:07,910 --> 02:45:06,240
time but go navigator still has a fully

3527
02:45:10,790 --> 02:45:07,920
functional prime

3528
02:45:12,630 --> 02:45:10,800
generator on board and not having that

3529
02:45:14,710 --> 02:45:12,640
backup is not

3530
02:45:17,830 --> 02:45:14,720
any constraint on normal recovery

3531
02:45:19,990 --> 02:45:17,840
options this morning so go navigator

3532
02:45:21,269 --> 02:45:20,000
steaming full speed ahead heading to

3533
02:45:23,990 --> 02:45:21,279
that recovery zone and they're going to

3534
02:45:26,070 --> 02:45:24,000
be there several hours before splashdown

3535
02:45:27,429 --> 02:45:26,080
they'll maintain a distance of about

3536
02:45:29,990 --> 02:45:27,439
three nautical miles from the

3537
02:45:31,990 --> 02:45:30,000
anticipated splashdown point and just be

3538
02:45:34,469 --> 02:45:32,000
ready and on standby for when bob and

3539
02:45:36,790 --> 02:45:34,479
doug are in the water yeah as you may

3540
02:45:38,950 --> 02:45:36,800
have heard us mentioned before it has

3541
02:45:41,510 --> 02:45:38,960
been at least over the last week the

3542
02:45:43,269 --> 02:45:41,520
recovery team has been really busy with

3543
02:45:45,510 --> 02:45:43,279
trying to determine where exactly we

3544
02:45:47,750 --> 02:45:45,520
were going to point dragon for its

3545
02:45:49,269 --> 02:45:47,760
return home

3546
02:45:51,990 --> 02:45:49,279
in order to

3547
02:45:54,870 --> 02:45:52,000
allow for

3548
02:45:57,670 --> 02:45:54,880
multiple depart excuse me allowed to in

3549
02:45:59,670 --> 02:45:57,680
order to allow for multiple

3550
02:46:01,190 --> 02:45:59,680
departure

3551
02:46:02,950 --> 02:46:01,200
times from the international space

3552
02:46:05,910 --> 02:46:02,960
station so again this is just trying to

3553
02:46:08,389 --> 02:46:05,920
line up things like crew sleep schedules

3554
02:46:10,710 --> 02:46:08,399
and weather and just physical location

3555
02:46:14,150 --> 02:46:10,720
as it is orbiting earth we identified

3556
02:46:16,070 --> 02:46:14,160
seven potential uh splashdown locations

3557
02:46:18,309 --> 02:46:16,080
four on the east yeah four on the west

3558
02:46:20,790 --> 02:46:18,319
coast of florida and three on the east

3559
02:46:23,269 --> 02:46:20,800
coast and it has been priority number

3560
02:46:25,269 --> 02:46:23,279
one for the last week for the recovery

3561
02:46:27,110 --> 02:46:25,279
team to determine which of those seven

3562
02:46:29,349 --> 02:46:27,120
locations bob and doug would be

3563
02:46:32,150 --> 02:46:29,359
splashing down at

3564
02:46:34,469 --> 02:46:32,160
the weather around florida is

3565
02:46:36,469 --> 02:46:34,479
ever changing especially when you have

3566
02:46:39,429 --> 02:46:36,479
something like as we currently have a

3567
02:46:41,670 --> 02:46:39,439
tropical storm rolling through the area

3568
02:46:44,870 --> 02:46:41,680
having that storm

3569
02:46:46,630 --> 02:46:44,880
roll up the east coast of florida

3570
02:46:48,469 --> 02:46:46,640
had prevented us from obviously being

3571
02:46:50,790 --> 02:46:48,479
able to land at any of those so

3572
02:46:53,030 --> 02:46:50,800
selection was then narrowed down to the

3573
02:46:55,269 --> 02:46:53,040
four in the gulf of mexico on the west

3574
02:46:57,670 --> 02:46:55,279
coast of florida and we continue to

3575
02:46:59,510 --> 02:46:57,680
evaluate the weather at designated

3576
02:47:02,550 --> 02:46:59,520
intervals and

3577
02:47:05,349 --> 02:47:02,560
we were able to determine that the best

3578
02:47:07,429 --> 02:47:05,359
location for recovery would be off the

3579
02:47:09,590 --> 02:47:07,439
coast of pensacola

3580
02:47:10,550 --> 02:47:09,600
condition or excuse me requirements for

3581
02:47:11,590 --> 02:47:10,560
these

3582
02:47:14,070 --> 02:47:11,600
landing

3583
02:47:15,910 --> 02:47:14,080
zones neat are essentially that they

3584
02:47:18,150 --> 02:47:15,920
need to can't be in the middle of the

3585
02:47:20,790 --> 02:47:18,160
body of water because the landing zone

3586
02:47:23,429 --> 02:47:20,800
has to be close to a medical facility

3587
02:47:25,269 --> 02:47:23,439
and it has to be close to a port

3588
02:47:28,630 --> 02:47:25,279
so that the recovery vessel can actually

3589
02:47:30,150 --> 02:47:28,640
get to and from the recovery to and from

3590
02:47:32,630 --> 02:47:30,160
the landing site

3591
02:47:34,950 --> 02:47:32,640
yeah and we've continued to watch the

3592
02:47:37,190 --> 02:47:34,960
weather we got pretty lucky with the

3593
02:47:39,349 --> 02:47:37,200
weather that we're looking at today we

3594
02:47:41,190 --> 02:47:39,359
had some weather criteria that we're

3595
02:47:43,590 --> 02:47:41,200
looking for we have to meet those

3596
02:47:45,990 --> 02:47:43,600
criteria in order to get basically a go

3597
02:47:47,349 --> 02:47:46,000
condition to splash down one of the main

3598
02:47:49,190 --> 02:47:47,359
things we were looking at was wind

3599
02:47:52,309 --> 02:47:49,200
speeds which we were looking to not

3600
02:47:54,230 --> 02:47:52,319
exceed 10 miles an hour and winds in the

3601
02:47:56,309 --> 02:47:54,240
splashdown zone right now just barely

3602
02:47:59,269 --> 02:47:56,319
over one mile an hour so getting

3603
02:48:01,750 --> 02:47:59,279
extremely calm winds and very calm seas

3604
02:48:04,389 --> 02:48:01,760
for what should be a very stable

3605
02:48:06,950 --> 02:48:04,399
operation for this recovery today we

3606
02:48:09,110 --> 02:48:06,960
actually just locked in

3607
02:48:12,150 --> 02:48:09,120
panama city a few hours ago

3608
02:48:14,230 --> 02:48:12,160
our kind of last chance to lock in an

3609
02:48:16,230 --> 02:48:14,240
alternate site i was

3610
02:48:19,670 --> 02:48:16,240
just a little over an hour and a half

3611
02:48:21,910 --> 02:48:19,680
ago at about 5 48 a.m pacific dragon has

3612
02:48:24,070 --> 02:48:21,920
the capability to change alternate sites

3613
02:48:26,870 --> 02:48:24,080
once it's in free flight

3614
02:48:28,950 --> 02:48:26,880
and we do have again seven different uh

3615
02:48:30,630 --> 02:48:28,960
splashdown locations uh just based off

3616
02:48:32,389 --> 02:48:30,640
of the weather

3617
02:48:34,150 --> 02:48:32,399
and everything else that we looked at

3618
02:48:36,070 --> 02:48:34,160
panama said it was chosen as the

3619
02:48:37,670 --> 02:48:36,080
alternate for this opportunity that was

3620
02:48:39,190 --> 02:48:37,680
already looking like our best one just

3621
02:48:41,670 --> 02:48:39,200
based off the weather and they just

3622
02:48:43,830 --> 02:48:41,680
locked that in a few hours ago but

3623
02:48:45,670 --> 02:48:43,840
everything continuing on track for this

3624
02:48:48,150 --> 02:48:45,680
pensacola splashdown

3625
02:48:50,230 --> 02:48:48,160
go navigator is well on its way to the

3626
02:48:51,670 --> 02:48:50,240
splashdown location and bob and duggar

3627
02:48:54,389 --> 02:48:51,680
just a couple of hours away from that

3628
02:48:55,990 --> 02:48:54,399
deorbit burn

3629
02:48:58,550 --> 02:48:56,000
we are taking your questions this

3630
02:49:01,349 --> 02:48:58,560
morning from twitter be sure to use the

3631
02:49:03,990 --> 02:49:01,359
hashtag asknasa and we'll try to cycle

3632
02:49:06,230 --> 02:49:04,000
through as many of them as we can get to

3633
02:49:09,269 --> 02:49:06,240
this question comes from tim

3634
02:49:10,550 --> 02:49:09,279
what's the current distance to the iss

3635
02:49:13,510 --> 02:49:10,560
good question

3636
02:49:15,349 --> 02:49:13,520
something that i find that people people

3637
02:49:17,269 --> 02:49:15,359
often assume is that the international

3638
02:49:19,910 --> 02:49:17,279
space station is

3639
02:49:22,750 --> 02:49:19,920
really really far away and it's actually

3640
02:49:26,469 --> 02:49:22,760
not uh it is about

3641
02:49:29,590 --> 02:49:26,479
250 to 300 miles above the earth i think

3642
02:49:31,190 --> 02:49:29,600
when i saw a report earlier or maybe it

3643
02:49:33,389 --> 02:49:31,200
was actually leah who mentioned it in

3644
02:49:36,150 --> 02:49:33,399
the earlier broadcast i think it's about

3645
02:49:38,710 --> 02:49:36,160
263 miles above the earth's surface

3646
02:49:40,469 --> 02:49:38,720
right now so depending on

3647
02:49:41,910 --> 02:49:40,479
you know where it is in its orbit it

3648
02:49:44,790 --> 02:49:41,920
might be a little higher it might be a

3649
02:49:46,469 --> 02:49:44,800
little lower uh and yeah so it is it's

3650
02:49:48,710 --> 02:49:46,479
actually not that far away it's

3651
02:49:51,590 --> 02:49:48,720
basically the distance from los angeles

3652
02:49:54,230 --> 02:49:51,600
to san francisco uh you know as the crow

3653
02:49:57,269 --> 02:49:54,240
flies uh just above us so it's really

3654
02:50:01,110 --> 02:49:57,279
not as far as as many people think

3655
02:50:02,710 --> 02:50:01,120
again this is using the hashtag ask nasa

3656
02:50:03,750 --> 02:50:02,720
this next question comes to us from

3657
02:50:05,750 --> 02:50:03,760
nicholas

3658
02:50:08,150 --> 02:50:05,760
how far off the coast will the castle

3659
02:50:10,550 --> 02:50:08,160
land will it be possible to see any of

3660
02:50:12,870 --> 02:50:10,560
the action from the coastline trying to

3661
02:50:14,630 --> 02:50:12,880
find our exact distances it varies

3662
02:50:16,550 --> 02:50:14,640
depending on which coast that we're

3663
02:50:18,790 --> 02:50:16,560
going to

3664
02:50:20,309 --> 02:50:18,800
we do stay far enough away that you

3665
02:50:21,349 --> 02:50:20,319
wouldn't really be able to see it from

3666
02:50:22,950 --> 02:50:21,359
the coast

3667
02:50:25,349 --> 02:50:22,960
obviously you do want to still be coming

3668
02:50:26,630 --> 02:50:25,359
down in an area pretty far away from

3669
02:50:28,309 --> 02:50:26,640
land to make sure you're hitting a

3670
02:50:30,630 --> 02:50:28,319
splashdown zone

3671
02:50:32,790 --> 02:50:30,640
and just so you're not near any

3672
02:50:34,550 --> 02:50:32,800
major air traffic areas things like that

3673
02:50:37,269 --> 02:50:34,560
as you do have to clear

3674
02:50:39,830 --> 02:50:37,279
air zones we have to make sure that we

3675
02:50:41,750 --> 02:50:39,840
have notices going out to ships not to

3676
02:50:44,630 --> 02:50:41,760
go into a certain area

3677
02:50:47,269 --> 02:50:44,640
but they're just uh several kilometers

3678
02:50:48,950 --> 02:50:47,279
obviously or several miles offshore

3679
02:50:51,349 --> 02:50:48,960
the cape is the closest one that one's

3680
02:50:54,309 --> 02:50:51,359
typically only about 24 miles offshore

3681
02:50:56,710 --> 02:50:54,319
the other ones range anywhere from

3682
02:50:59,190 --> 02:50:56,720
about 50 miles all the way up to a few

3683
02:51:01,590 --> 02:50:59,200
hundred just about 200 or so when we

3684
02:51:05,110 --> 02:51:01,600
landed demo one last year was about 240

3685
02:51:06,309 --> 02:51:05,120
miles off off of the cape so it is it is

3686
02:51:07,269 --> 02:51:06,319
different depending on where you're

3687
02:51:08,230 --> 02:51:07,279
going

3688
02:51:10,309 --> 02:51:08,240
but

3689
02:51:12,469 --> 02:51:10,319
one of the things that we have

3690
02:51:15,110 --> 02:51:12,479
in our basically our recovery arsenal

3691
02:51:17,190 --> 02:51:15,120
are helicopters where bob and doug will

3692
02:51:19,590 --> 02:51:17,200
get recovered by that

3693
02:51:21,429 --> 02:51:19,600
main recovery vessel the go navigator

3694
02:51:23,269 --> 02:51:21,439
and after they're out of the capsule and

3695
02:51:25,429 --> 02:51:23,279
into the medical facility a helicopter

3696
02:51:27,190 --> 02:51:25,439
will come and land on the deck and then

3697
02:51:29,349 --> 02:51:27,200
it's only about a 10 minute helicopter

3698
02:51:31,429 --> 02:51:29,359
ride from the go navigator back to

3699
02:51:33,269 --> 02:51:31,439
pensacola where they'll be moving on to

3700
02:51:34,469 --> 02:51:33,279
a nasa plane ready to take them over to

3701
02:51:37,510 --> 02:51:34,479
houston

3702
02:51:39,269 --> 02:51:37,520
yeah so one thing to note um the

3703
02:51:42,230 --> 02:51:39,279
capsule will be re-entering earth's

3704
02:51:44,870 --> 02:51:42,240
atmosphere and we will have parachute

3705
02:51:48,870 --> 02:51:44,880
deployment starting at about 18 000 feet

3706
02:51:50,950 --> 02:51:48,880
above the surface of the gulf of mexico

3707
02:51:53,990 --> 02:51:50,960
those drogue parachutes and the capsule

3708
02:51:57,910 --> 02:51:54,000
itself dragon spacex for timeline and

3709
02:52:12,150 --> 02:51:59,910
we should be getting an update up to the

3710
02:52:14,389 --> 02:52:12,830
go

3711
02:52:17,269 --> 02:52:14,399
ahead

3712
02:52:20,150 --> 02:52:17,279
okay first off for timeline update uh we

3713
02:52:22,309 --> 02:52:20,160
are now within 4.5 hours of splashdown

3714
02:52:29,190 --> 02:52:22,319
for contingency planning purposes how

3715
02:52:35,190 --> 02:52:32,630
4.5 for splashdown capill

3716
02:52:37,349 --> 02:52:35,200
okay for recovery forces i believe jay

3717
02:52:39,910 --> 02:52:37,359
told you that we were working a backup

3718
02:52:42,070 --> 02:52:39,920
generator on the recovery vessel

3719
02:52:44,630 --> 02:52:42,080
unfortunately we're unable to get that

3720
02:52:47,590 --> 02:52:44,640
generator aboard before go navigator had

3721
02:52:49,590 --> 02:52:47,600
to depart due to timing constraints

3722
02:52:51,190 --> 02:52:49,600
however go navigator has departed and

3723
02:53:05,349 --> 02:52:51,200
we're expecting and is expected to be

3724
02:53:08,309 --> 02:53:06,469
okay

3725
02:53:11,670 --> 02:53:08,319
go navigator will be on site time for

3726
02:53:15,349 --> 02:53:14,070
yep good read back and uh as jay

3727
02:53:17,190 --> 02:53:15,359
mentioned before

3728
02:53:25,830 --> 02:53:17,200
we're down to one generator due to the

3729
02:53:25,840 --> 02:53:38,950
yep

3730
02:53:42,469 --> 02:53:41,269
so that was just a real quick update

3731
02:53:44,870 --> 02:53:42,479
on giving

3732
02:53:46,309 --> 02:53:44,880
the crew on board dragon the latest as

3733
02:53:48,950 --> 02:53:46,319
you just heard

3734
02:53:52,070 --> 02:53:48,960
go navigator on its way it's expected to

3735
02:53:53,750 --> 02:53:52,080
be in the splashdown zone on time for

3736
02:53:55,269 --> 02:53:53,760
their descent again we're targeting a

3737
02:53:59,110 --> 02:53:55,279
splashdown

3738
02:54:01,110 --> 02:53:59,120
at 11 48 a.m pacific 1848 gmt or

3739
02:54:02,710 --> 02:54:01,120
universal time

3740
02:54:03,590 --> 02:54:02,720
and they talked through the generator

3741
02:54:05,429 --> 02:54:03,600
issue

3742
02:54:08,309 --> 02:54:05,439
the go navigator still fully equipped to

3743
02:54:09,670 --> 02:54:08,319
safely recover the crew this afternoon

3744
02:54:12,150 --> 02:54:09,680
or this morning

3745
02:54:14,150 --> 02:54:12,160
but they are down one of the generators

3746
02:54:16,389 --> 02:54:14,160
on board still able to use that

3747
02:54:18,230 --> 02:54:16,399
hydraulic lift get dragon up out of the

3748
02:54:21,670 --> 02:54:18,240
water and on board

3749
02:54:23,750 --> 02:54:21,680
the ship itself has a full deck area

3750
02:54:25,429 --> 02:54:23,760
where it has an a-frame on the very back

3751
02:54:27,190 --> 02:54:25,439
of the ship and we'll get some views

3752
02:54:28,870 --> 02:54:27,200
from the boat throughout the operations

3753
02:54:31,670 --> 02:54:28,880
once we get a little bit closer into the

3754
02:54:34,150 --> 02:54:31,680
recovery zone but that a-frame used to

3755
02:54:36,230 --> 02:54:34,160
physically lift dragon out of the water

3756
02:54:38,230 --> 02:54:36,240
and onto the deck the crew stays in

3757
02:54:40,230 --> 02:54:38,240
their suits in their seats the entire

3758
02:54:41,590 --> 02:54:40,240
time they're in the water as long as

3759
02:54:43,349 --> 02:54:41,600
everything is following the nominal

3760
02:54:44,950 --> 02:54:43,359
timeline and they'll get picked up out

3761
02:54:47,190 --> 02:54:44,960
of the water and put into the dragon

3762
02:54:48,550 --> 02:54:47,200
nest on the boat eventually moved under

3763
02:54:51,110 --> 02:54:48,560
the hella deck

3764
02:54:52,870 --> 02:54:51,120
up to a crew access platform where we'll

3765
02:54:54,389 --> 02:54:52,880
have some people standing by to open up

3766
02:54:57,110 --> 02:54:54,399
the hatch and it says bob and doug

3767
02:54:59,030 --> 02:54:57,120
getting out yeah so just real quick uh

3768
02:55:01,190 --> 02:54:59,040
going back to the twitter question that

3769
02:55:03,349 --> 02:55:01,200
we had a minute ago if

3770
02:55:05,830 --> 02:55:03,359
action would be available to view from

3771
02:55:07,030 --> 02:55:05,840
onshore i just did a little bit of

3772
02:55:08,550 --> 02:55:07,040
sleuthing

3773
02:55:11,190 --> 02:55:08,560
and i

3774
02:55:13,190 --> 02:55:11,200
due to the the splashdown location i do

3775
02:55:15,670 --> 02:55:13,200
think that if you're in the pensacola

3776
02:55:17,750 --> 02:55:15,680
area you might be able to spot the main

3777
02:55:19,670 --> 02:55:17,760
parachute deployment

3778
02:55:23,269 --> 02:55:19,680
or after they inflate those main

3779
02:55:25,030 --> 02:55:23,279
parachutes are deployed around 6000 feet

3780
02:55:27,110 --> 02:55:25,040
whenever dragon is descending about when

3781
02:55:29,110 --> 02:55:27,120
it hits about 6000 feet above the

3782
02:55:31,349 --> 02:55:29,120
earth's about above the surface of the

3783
02:55:33,269 --> 02:55:31,359
ocean those main parachutes will deploy

3784
02:55:35,349 --> 02:55:33,279
and it takes a about a minute or so for

3785
02:55:36,309 --> 02:55:35,359
them to fully

3786
02:55:38,950 --> 02:55:36,319
uh

3787
02:55:41,349 --> 02:55:38,960
deploy out into their larger state state

3788
02:55:43,190 --> 02:55:41,359
capturing all that air flow

3789
02:55:44,870 --> 02:55:43,200
but it is possible that i think that if

3790
02:55:46,309 --> 02:55:44,880
you're in the pensacola area and you

3791
02:55:47,590 --> 02:55:46,319
have really keen eyes you might be able

3792
02:55:50,230 --> 02:55:47,600
to spot those orange and white

3793
02:55:52,070 --> 02:55:50,240
parachutes off in the distance again the

3794
02:55:55,429 --> 02:55:52,080
capsule you know from that distance

3795
02:55:56,950 --> 02:55:55,439
would be pretty small so no promises but

3796
02:55:59,910 --> 02:55:56,960
it might be worth a look so if you're in

3797
02:56:01,510 --> 02:55:59,920
pensacola take a look south uh and

3798
02:56:02,710 --> 02:56:01,520
around 11

3799
02:56:11,830 --> 02:56:02,720
48

3800
02:56:13,750 --> 02:56:11,840
we call an ascending approach so if

3801
02:56:16,309 --> 02:56:13,760
you're at pensacola looking south the

3802
02:56:18,070 --> 02:56:16,319
capsule will be heading towards you from

3803
02:56:20,469 --> 02:56:18,080
the south it's going to be moving from

3804
02:56:23,269 --> 02:56:20,479
southeast to north southwest to

3805
02:56:24,710 --> 02:56:23,279
northeast across the gulf of mexico as

3806
02:56:27,110 --> 02:56:24,720
it makes this approach there are also

3807
02:56:29,349 --> 02:56:27,120
what we call descending orbits so

3808
02:56:30,230 --> 02:56:29,359
essentially when dragon is traveling

3809
02:56:31,990 --> 02:56:30,240
from

3810
02:56:34,469 --> 02:56:32,000
the northwest down to the southeast

3811
02:56:36,790 --> 02:56:34,479
which would actually bring it over

3812
02:56:38,630 --> 02:56:36,800
the u.s before it's flashed down but we

3813
02:56:40,710 --> 02:56:38,640
are on an ascending one today so it's

3814
02:56:43,269 --> 02:56:40,720
largely going to be over the gulf the

3815
02:56:44,070 --> 02:56:43,279
whole way in during that final decision

3816
02:56:46,150 --> 02:56:44,080
yeah

3817
02:56:48,150 --> 02:56:46,160
so again we are taking your questions

3818
02:56:50,469 --> 02:56:48,160
through twitter this morning be sure to

3819
02:56:51,910 --> 02:56:50,479
use the hashtag ask nasa and we're going

3820
02:56:54,070 --> 02:56:51,920
to try to get to as many of them as we

3821
02:56:55,910 --> 02:56:54,080
can this morning the next question comes

3822
02:56:58,630 --> 02:56:55,920
to us from andrew

3823
02:57:02,389 --> 02:56:58,640
he asks why can't dragon ball dragon for

3824
02:57:02,399 --> 02:57:09,190
go for spacex

3825
02:57:14,550 --> 02:57:11,429
yeah mike could you take the interior

3826
02:57:28,389 --> 02:57:14,560
cameras down for a few minutes

3827
02:57:32,870 --> 02:57:30,309
the crew just making a quick ask having

3828
02:57:34,950 --> 02:57:32,880
those interior cameras brought down

3829
02:57:37,110 --> 02:57:34,960
they work with the teams on the ground a

3830
02:57:39,269 --> 02:57:37,120
lot like those on space station they

3831
02:57:41,349 --> 02:57:39,279
have cameras in there just so they're

3832
02:57:42,870 --> 02:57:41,359
able to get kind of rapid response any

3833
02:57:44,309 --> 02:57:42,880
questions that they have any help that

3834
02:57:46,150 --> 02:57:44,319
they need but then obviously the

3835
02:57:47,910 --> 02:57:46,160
astronauts getting the privacy they need

3836
02:57:49,990 --> 02:57:47,920
when they're doing suit up or just kind

3837
02:57:52,630 --> 02:57:50,000
of anything else where you don't need

3838
02:57:54,389 --> 02:57:52,640
people checking in on you yeah

3839
02:57:56,309 --> 02:57:54,399
so again going back to this question

3840
02:57:59,269 --> 02:57:56,319
from andrew coming to us from the

3841
02:58:01,429 --> 02:57:59,279
hashtag ask nasa on twitter why can't

3842
02:58:03,349 --> 02:58:01,439
dragon make a straight downward descent

3843
02:58:05,030 --> 02:58:03,359
instead of orbiting around the world

3844
02:58:07,110 --> 02:58:05,040
that is a great question

3845
02:58:08,469 --> 02:58:07,120
you have to keep in mind that when

3846
02:58:11,030 --> 02:58:08,479
dragon

3847
02:58:15,429 --> 02:58:11,040
is at the international space station it

3848
02:58:18,230 --> 02:58:15,439
is at the same velocity it is going 17

3849
02:58:21,910 --> 02:58:18,240
500 miles per hour and it is orbiting

3850
02:58:23,750 --> 02:58:21,920
the earth in order to have it perform a

3851
02:58:26,230 --> 02:58:23,760
landing of straight down you would have

3852
02:58:28,309 --> 02:58:26,240
to have some sort of force to stop it

3853
02:58:30,389 --> 02:58:28,319
going from that fast

3854
02:58:32,950 --> 02:58:30,399
and that's really not possible due to

3855
02:58:34,469 --> 02:58:32,960
constraints like having enough fuel and

3856
02:58:35,510 --> 02:58:34,479
size of the capsule and all that good

3857
02:58:38,150 --> 02:58:35,520
stuff

3858
02:58:44,950 --> 02:58:38,160
so try again we should be external

3859
02:58:48,630 --> 02:58:47,030
thanks mike

3860
02:58:51,750 --> 02:58:48,640
so there was that confirmation from

3861
02:58:53,670 --> 02:58:51,760
spacex core uh that the internal cabin

3862
02:58:56,550 --> 02:58:53,680
cameras have been shut off

3863
02:58:57,990 --> 02:58:56,560
uh so dragon's reentry is the uh can't

3864
02:58:59,510 --> 02:58:58,000
be straight down because you would need

3865
02:59:02,230 --> 02:58:59,520
some sort of force

3866
02:59:04,309 --> 02:59:02,240
in order to stop it thanks to i think

3867
02:59:07,590 --> 02:59:04,319
it's newton's second law

3868
02:59:09,830 --> 02:59:07,600
that being said an orbital re-entry like

3869
02:59:11,510 --> 02:59:09,840
we do use is

3870
02:59:14,870 --> 02:59:11,520
highly calculable

3871
02:59:17,590 --> 02:59:14,880
we are able to have very precise details

3872
02:59:19,670 --> 02:59:17,600
in terms of where it's going to land and

3873
02:59:21,670 --> 02:59:19,680
at what time so

3874
02:59:23,510 --> 02:59:21,680
they're really you know there's no

3875
02:59:25,830 --> 02:59:23,520
downside to doing it in the way that we

3876
02:59:27,910 --> 02:59:25,840
do do it other than the fact that from a

3877
02:59:32,630 --> 02:59:27,920
physics standpoint the straight down

3878
02:59:37,429 --> 02:59:35,590
all right so our next question

3879
02:59:39,110 --> 02:59:37,439
uh from elaine what difference is there

3880
02:59:40,309 --> 02:59:39,120
in the route map from the red and the

3881
02:59:42,070 --> 02:59:40,319
yellow line

3882
02:59:44,469 --> 02:59:42,080
i think he touched on this a little bit

3883
02:59:48,070 --> 02:59:44,479
earlier that's showing you where dragon

3884
02:59:51,030 --> 02:59:48,080
is essentially in sunlight or an eclipse

3885
02:59:52,469 --> 02:59:51,040
we don't have shades on this map but

3886
02:59:54,710 --> 02:59:52,479
if you look at the red parts that's

3887
02:59:56,710 --> 02:59:54,720
where dragon is essentially on the dark

3888
02:59:58,950 --> 02:59:56,720
side of the planet at that point in the

3889
03:00:02,870 --> 02:59:58,960
orbit and then the yellow line in the

3890
03:00:05,190 --> 03:00:02,880
orbit is where it's in sunlight so

3891
03:00:06,950 --> 03:00:05,200
obviously matching up with

3892
03:00:08,790 --> 03:00:06,960
the sunlight for all of us down on

3893
03:00:10,870 --> 03:00:08,800
planet earth the sun i think it's up

3894
03:00:12,710 --> 03:00:10,880
here in california

3895
03:00:13,429 --> 03:00:12,720
there aren't many windows

3896
03:00:15,269 --> 03:00:13,439
but

3897
03:00:17,429 --> 03:00:15,279
that's that's all that line is segment

3898
03:00:19,030 --> 03:00:17,439
is signaling and you might wonder why

3899
03:00:20,870 --> 03:00:19,040
are there two lines it kind of looks

3900
03:00:23,910 --> 03:00:20,880
like uh it's actually just one

3901
03:00:27,429 --> 03:00:23,920
continuous line um and just to run you

3902
03:00:29,590 --> 03:00:27,439
down real quick again uh dragon is

3903
03:00:31,510 --> 03:00:29,600
in kind of the top right portion of your

3904
03:00:33,510 --> 03:00:31,520
screen right now uh there's a little

3905
03:00:35,910 --> 03:00:33,520
circle with the dragon icon it's

3906
03:00:38,070 --> 03:00:35,920
currently just uh to the north of india

3907
03:00:39,670 --> 03:00:38,080
flying over china it's going to continue

3908
03:00:41,510 --> 03:00:39,680
on this southeasterly path over

3909
03:00:43,750 --> 03:00:41,520
southeast asia

3910
03:00:45,990 --> 03:00:43,760
it's about to head into an orbital night

3911
03:00:49,269 --> 03:00:46,000
time which means things will get dark

3912
03:00:51,269 --> 03:00:49,279
for the spacecraft and the crew on board

3913
03:00:53,349 --> 03:00:51,279
and that also means it's about to cross

3914
03:00:55,670 --> 03:00:53,359
what's known as the terminator line that

3915
03:00:57,830 --> 03:00:55,680
is the line between night and day on the

3916
03:00:59,429 --> 03:00:57,840
earth's surface and when you're

3917
03:01:01,670 --> 03:00:59,439
on board the international space station

3918
03:01:04,950 --> 03:01:01,680
or in this case onboard dragon you can

3919
03:01:07,910 --> 03:01:04,960
get some pretty spectacular views uh as

3920
03:01:10,070 --> 03:01:07,920
uh the earth goes from night to almost

3921
03:01:12,550 --> 03:01:10,080
pitch black beneath you

3922
03:01:14,389 --> 03:01:12,560
yeah one of my favorite views that we

3923
03:01:15,349 --> 03:01:14,399
get from the international space station

3924
03:01:16,550 --> 03:01:15,359
is

3925
03:01:19,269 --> 03:01:16,560
as they are

3926
03:01:21,750 --> 03:01:19,279
transitioning from day to night and

3927
03:01:24,070 --> 03:01:21,760
night today you you get to see the sun

3928
03:01:24,870 --> 03:01:24,080
rises and sunset from their perspective

3929
03:01:26,550 --> 03:01:24,880
and

3930
03:01:28,630 --> 03:01:26,560
i just absolutely love it when we

3931
03:01:29,990 --> 03:01:28,640
actually get to see the lightning as

3932
03:01:33,110 --> 03:01:30,000
well

3933
03:01:35,349 --> 03:01:33,120
it's just such a cool phenomenon to

3934
03:01:36,870 --> 03:01:35,359
view from above

3935
03:01:39,269 --> 03:01:36,880
so we'll we'll hang out for a few

3936
03:01:41,349 --> 03:01:39,279
minutes here and watch dragon's track as

3937
03:01:43,670 --> 03:01:41,359
they continue to circle the globe we're

3938
03:01:45,429 --> 03:01:43,680
still about three hours away from things

3939
03:01:47,349 --> 03:01:45,439
really starting to pick up when we get

3940
03:01:48,710 --> 03:01:47,359
into trunk separation and deorbit burn

3941
03:01:50,630 --> 03:01:48,720
but we're going to continue to stick

3942
03:01:52,550 --> 03:01:50,640
with it as we get ready to welcome bob

3943
03:17:30,309 --> 03:01:52,560
and doug home a little bit later this

3944
03:17:34,790 --> 03:17:32,790
all right if you're just now tuning in

3945
03:17:36,389 --> 03:17:34,800
we're still following bob and doug's

3946
03:17:38,790 --> 03:17:36,399
journey back home

3947
03:17:40,469 --> 03:17:38,800
on the conclusion of our demo two

3948
03:17:42,389 --> 03:17:40,479
mission

3949
03:17:46,070 --> 03:17:42,399
just to walk you through how we got here

3950
03:17:47,830 --> 03:17:46,080
everything started back on saturday when

3951
03:17:49,830 --> 03:17:47,840
they made their way into the dragon

3952
03:17:51,030 --> 03:17:49,840
spacecraft where

3953
03:17:53,110 --> 03:17:51,040
they had been living on board the

3954
03:17:55,030 --> 03:17:53,120
international space station for about 62

3955
03:17:57,750 --> 03:17:55,040
days and by the time they splash down

3956
03:17:59,750 --> 03:17:57,760
they'll be just shy of 64 total days

3957
03:18:01,590 --> 03:17:59,760
spent in space everything started with

3958
03:18:03,750 --> 03:18:01,600
hatch clothes after bob and doug made

3959
03:18:06,469 --> 03:18:03,760
their way into the dragon spacecraft

3960
03:18:07,990 --> 03:18:06,479
closing up the hatch on their side

3961
03:18:10,070 --> 03:18:08,000
after that they were able to get the

3962
03:18:11,750 --> 03:18:10,080
hatch closed on the station side closing

3963
03:18:14,070 --> 03:18:11,760
what's known as the eight pass hatch it

3964
03:18:16,309 --> 03:18:14,080
also had a docking target affixed to it

3965
03:18:19,429 --> 03:18:16,319
but that created an area between the two

3966
03:18:21,670 --> 03:18:19,439
known as the vestibule that vestibule

3967
03:18:23,670 --> 03:18:21,680
gets exposed to the vacuum of space

3968
03:18:25,750 --> 03:18:23,680
following the undocking so we first have

3969
03:18:27,190 --> 03:18:25,760
to depressurize it basically draw all of

3970
03:18:29,269 --> 03:18:27,200
the air out

3971
03:18:32,070 --> 03:18:29,279
after that and some leak checks are

3972
03:18:34,389 --> 03:18:32,080
completed the crew gets ready for their

3973
03:18:36,389 --> 03:18:34,399
actual departure from the international

3974
03:18:38,550 --> 03:18:36,399
space station the teams on the ground

3975
03:18:40,710 --> 03:18:38,560
both here in hawthorne and in mission

3976
03:18:42,710 --> 03:18:40,720
control houston did a go no go basically

3977
03:18:45,349 --> 03:18:42,720
we check everything on dragon everything

3978
03:18:48,309 --> 03:18:45,359
on station and get them ready for

3979
03:18:50,550 --> 03:18:48,319
departure following a successful go for

3980
03:18:53,349 --> 03:18:50,560
undocking it's time to actually move

3981
03:18:55,429 --> 03:18:53,359
dragon away and separation takes place a

3982
03:18:57,590 --> 03:18:55,439
docking command was sent and then just

3983
03:18:59,990 --> 03:18:57,600
about five minutes later dragon fired

3984
03:19:01,750 --> 03:19:00,000
its thrusters two small bursts to

3985
03:19:04,790 --> 03:19:01,760
separate from the international space

3986
03:19:07,910 --> 03:19:04,800
station it then begins to fly away and

3987
03:19:10,469 --> 03:19:07,920
did so yesterday evening doing four

3988
03:19:12,309 --> 03:19:10,479
departure burns to bring it first up and

3989
03:19:14,790 --> 03:19:12,319
over the international space station

3990
03:19:17,110 --> 03:19:14,800
eventually passing beneath and out in

3991
03:19:18,790 --> 03:19:17,120
front all four of those departure burns

3992
03:19:20,790 --> 03:19:18,800
done successfully

3993
03:19:22,870 --> 03:19:20,800
by that point dragon's opening rate away

3994
03:19:25,190 --> 03:19:22,880
from the station got larger and larger

3995
03:19:27,990 --> 03:19:25,200
and larger until it was time for it to

3996
03:19:30,389 --> 03:19:28,000
move into its departure phasing burn

3997
03:19:32,550 --> 03:19:30,399
this was one several minute long burn

3998
03:19:35,110 --> 03:19:32,560
about a six minute long burn to

3999
03:19:37,510 --> 03:19:35,120
fine-tune dragon's path to its eventual

4000
03:19:39,830 --> 03:19:37,520
splashdown site that was conducted

4001
03:19:41,830 --> 03:19:39,840
successfully last night after bob and

4002
03:19:43,590 --> 03:19:41,840
doug had gone to sleep

4003
03:19:45,110 --> 03:19:43,600
and then once that departure phasing

4004
03:19:47,510 --> 03:19:45,120
burn was in the book we only had one

4005
03:19:50,150 --> 03:19:47,520
more burn coming up down the line

4006
03:19:52,070 --> 03:19:50,160
and then if we were going to get uh

4007
03:19:53,990 --> 03:19:52,080
ready for this re-entry bob and doug did

4008
03:19:57,110 --> 03:19:54,000
have about an eight-hour cruise sleep

4009
03:19:59,269 --> 03:19:57,120
period um as is about a 19-hour trip

4010
03:20:01,830 --> 03:19:59,279
door-to-door from space station down to

4011
03:20:04,229 --> 03:20:01,840
the ocean off the coast of pensacola in

4012
03:20:05,110 --> 03:20:04,239
florida that crew sleep is completed

4013
03:20:07,990 --> 03:20:05,120
they will

4014
03:20:10,150 --> 03:20:08,000
they woke up a couple of hours ago and

4015
03:20:13,110 --> 03:20:10,160
our more dynamic action is about to pick

4016
03:20:15,030 --> 03:20:13,120
up soon yeah so our events coming up

4017
03:20:16,630 --> 03:20:15,040
next will be the claw and trunk

4018
03:20:18,389 --> 03:20:16,640
separation

4019
03:20:20,150 --> 03:20:18,399
this will essentially be

4020
03:20:21,750 --> 03:20:20,160
the final when we separate the trunk

4021
03:20:23,990 --> 03:20:21,760
it'll be the final physical form of

4022
03:20:26,229 --> 03:20:24,000
dragon prior to re-entry

4023
03:20:27,750 --> 03:20:26,239
we will then have exposed the heat

4024
03:20:30,229 --> 03:20:27,760
shield at the bottom of the capsule

4025
03:20:32,550 --> 03:20:30,239
after jettisoning that trunk allowing it

4026
03:20:35,030 --> 03:20:32,560
to get ready for its reentry

4027
03:20:36,630 --> 03:20:35,040
we put a deorbit burn

4028
03:20:38,469 --> 03:20:36,640
we activate the deorbit burn sequence

4029
03:20:40,950 --> 03:20:38,479
and that puts dragon on its final

4030
03:20:43,269 --> 03:20:40,960
trajectory to the landing site off the

4031
03:20:45,910 --> 03:20:43,279
coast of florida in the gulf of mexico

4032
03:20:48,550 --> 03:20:45,920
that deorbit burn will last about 10 and

4033
03:20:50,790 --> 03:20:48,560
excuse me 11 and a half minutes after

4034
03:20:53,030 --> 03:20:50,800
that two orbit burn completes we then

4035
03:20:55,510 --> 03:20:53,040
close the nose cone the deorbit burn

4036
03:20:57,990 --> 03:20:55,520
will utilize the four thrusters at the

4037
03:20:59,590 --> 03:20:58,000
top of dragon as you can see there we no

4038
03:21:01,269 --> 03:20:59,600
longer need to utilize them and we want

4039
03:21:02,790 --> 03:21:01,279
to protect the top hatch or excuse me

4040
03:21:04,630 --> 03:21:02,800
the forward hatch there so we close that

4041
03:21:07,030 --> 03:21:04,640
nose cone and lock it up

4042
03:21:08,870 --> 03:21:07,040
after that dragon will begin to re-enter

4043
03:21:10,630 --> 03:21:08,880
the earth's atmosphere and we will

4044
03:21:13,190 --> 03:21:10,640
experience a six minute long

4045
03:21:16,309 --> 03:21:13,200
communication blackout due to the plasma

4046
03:21:18,150 --> 03:21:16,319
building up on the exterior of cabin uh

4047
03:21:20,229 --> 03:21:18,160
due to the buildup of plasma on the

4048
03:21:22,229 --> 03:21:20,239
exterior of dragon

4049
03:21:24,469 --> 03:21:22,239
we won't be able to send

4050
03:21:26,630 --> 03:21:24,479
commands or receive telemetry but that's

4051
03:21:29,510 --> 03:21:26,640
okay dragon is completely autonomous it

4052
03:21:31,510 --> 03:21:29,520
is designed to steer itself anyway so uh

4053
03:21:34,790 --> 03:21:31,520
with that blackout communication period

4054
03:21:36,870 --> 03:21:34,800
will last for about six minutes or so um

4055
03:21:39,030 --> 03:21:36,880
after that about a couple minutes after

4056
03:21:41,349 --> 03:21:39,040
that we will after we regain those

4057
03:21:43,510 --> 03:21:41,359
communications with the crew we will

4058
03:21:45,910 --> 03:21:43,520
deploy the drogue parachutes these are

4059
03:21:47,830 --> 03:21:45,920
designed to slow the begin to slow the

4060
03:21:51,030 --> 03:21:47,840
vehicle down even further

4061
03:21:52,790 --> 03:21:51,040
and also to stabilize the dragon capsule

4062
03:21:55,910 --> 03:21:52,800
about a minute or two after drogue's

4063
03:21:57,590 --> 03:21:55,920
deploy will fire off the main parachutes

4064
03:21:59,910 --> 03:21:57,600
so these will be four orange and white

4065
03:22:02,070 --> 03:21:59,920
parachutes that will deploy and begin to

4066
03:22:04,630 --> 03:22:02,080
catch even more air and create more air

4067
03:22:08,469 --> 03:22:04,640
resistance slowing the vehicle down even

4068
03:22:11,590 --> 03:22:08,479
further to a mere 15 or 16 miles per

4069
03:22:14,070 --> 03:22:11,600
hour as the capsule then splashes down

4070
03:22:15,670 --> 03:22:14,080
in the gulf of mexico

4071
03:22:18,870 --> 03:22:15,680
we've located atlantic designated

4072
03:22:20,790 --> 03:22:18,880
landing location near pensacola florida

4073
03:22:22,389 --> 03:22:20,800
recovery operations then begin

4074
03:22:24,469 --> 03:22:22,399
immediately after splashdown is

4075
03:22:26,950 --> 03:22:24,479
confirmed the main parachutes will be

4076
03:22:29,030 --> 03:22:26,960
cut from the capsule autonomously

4077
03:22:31,510 --> 03:22:29,040
and the recovery crew will then begin to

4078
03:22:33,030 --> 03:22:31,520
move into position in order to retrieve

4079
03:22:35,670 --> 03:22:33,040
bob and doug

4080
03:22:37,830 --> 03:22:35,680
the team will actually be waiting three

4081
03:22:38,870 --> 03:22:37,840
nautical miles away from the splashdown

4082
03:22:41,030 --> 03:22:38,880
site

4083
03:22:43,190 --> 03:22:41,040
whenever the splashdown

4084
03:22:45,269 --> 03:22:43,200
approaches they will they will then

4085
03:22:47,190 --> 03:22:45,279
occurs they will then move closer

4086
03:22:48,950 --> 03:22:47,200
they will pull the caps get the capsule

4087
03:22:51,830 --> 03:22:48,960
ready to be lifted onto

4088
03:22:53,510 --> 03:22:51,840
the recovery vessel once that is secure

4089
03:22:56,710 --> 03:22:53,520
in the nest they'll then get to open the

4090
03:22:59,269 --> 03:22:56,720
hatch and have bob and doug egress or

4091
03:23:01,590 --> 03:22:59,279
exit from the dragon capsule and at that

4092
03:23:04,229 --> 03:23:01,600
moment it'll be their first breath of

4093
03:23:07,349 --> 03:23:04,239
fresh air in two months since they've

4094
03:23:09,429 --> 03:23:07,359
launched back on falcon 9 in late may

4095
03:23:11,510 --> 03:23:09,439
so we're really excited all of that will

4096
03:23:14,070 --> 03:23:11,520
be coming up shortly

4097
03:23:17,030 --> 03:23:14,080
those events that we have in the future

4098
03:23:18,870 --> 03:23:17,040
that the deorbit burn and the jettison

4099
03:23:20,790 --> 03:23:18,880
of the trunk

4100
03:23:23,750 --> 03:23:20,800
that will all be in

4101
03:23:26,070 --> 03:23:23,760
like three hours exactly so my countdown

4102
03:23:28,309 --> 03:23:26,080
here shows that the trunk separation uh

4103
03:23:30,630 --> 03:23:28,319
will be happening three hours from now

4104
03:23:33,110 --> 03:23:30,640
so we're looking forward to all of those

4105
03:23:35,429 --> 03:23:33,120
events coming up uh it has it's going to

4106
03:23:37,190 --> 03:23:35,439
be a very exciting morning like i said

4107
03:23:39,429 --> 03:23:37,200
seeing bob and doug for the first time

4108
03:23:40,950 --> 03:23:39,439
coming out um from the capsule on that

4109
03:23:43,349 --> 03:23:40,960
recovery vessel

4110
03:23:45,910 --> 03:23:43,359
go navigator will be the first time that

4111
03:23:47,510 --> 03:23:45,920
they are getting you know they're backed

4112
03:23:50,229 --> 03:23:47,520
out on planet earth for the first time

4113
03:23:53,030 --> 03:23:50,239
in two months safety is everything and

4114
03:23:55,990 --> 03:23:53,040
of course the human body uh experiences

4115
03:23:59,590 --> 03:23:56,000
microgravity and just to be safe we will

4116
03:24:03,030 --> 03:23:59,600
place them uh onto into a wheelchair or

4117
03:24:06,630 --> 03:24:04,469
my mind is structured

4118
03:24:08,710 --> 03:24:06,640
yeah there we go essentially we'll be

4119
03:24:10,950 --> 03:24:08,720
helping bob and doug as they get out of

4120
03:24:12,950 --> 03:24:10,960
the castle anybody who's familiar with

4121
03:24:14,710 --> 03:24:12,960
our long-duration crew members returning

4122
03:24:17,030 --> 03:24:14,720
to earth if you've ever seen a soyuz

4123
03:24:18,870 --> 03:24:17,040
landing you've seen the crew members get

4124
03:24:20,790 --> 03:24:18,880
physically lifted out of the capsule

4125
03:24:23,269 --> 03:24:20,800
typically and immediately carried over

4126
03:24:25,590 --> 03:24:23,279
to chairs where we're able to do quick

4127
03:24:27,349 --> 03:24:25,600
medical checks take things like pulse a

4128
03:24:29,590 --> 03:24:27,359
number of other items and just really

4129
03:24:31,349 --> 03:24:29,600
give them a moment to rest as it can be

4130
03:24:33,750 --> 03:24:31,359
pretty jarring on the body when you

4131
03:24:36,309 --> 03:24:33,760
re-enter into a gravity environment

4132
03:24:37,910 --> 03:24:36,319
after living in space for several months

4133
03:24:40,710 --> 03:24:37,920
so we're just doing everything we can

4134
03:24:42,630 --> 03:24:40,720
possibly to keep them safe not only just

4135
03:24:45,030 --> 03:24:42,640
physically once they get back we've also

4136
03:24:47,510 --> 03:24:45,040
had a lot of protocols put in place with

4137
03:24:49,110 --> 03:24:47,520
the current environment with coronavirus

4138
03:24:51,590 --> 03:24:49,120
just to make sure every member of our

4139
03:24:53,349 --> 03:24:51,600
recovery team has been self-isolated and

4140
03:24:56,150 --> 03:24:53,359
tested prior to being in that close

4141
03:24:57,910 --> 03:24:56,160
contact with bob and doug yeah so really

4142
03:24:59,830 --> 03:24:57,920
awesome morning we have coming up now

4143
03:25:02,309 --> 03:24:59,840
with respect to the covery ships

4144
03:25:04,229 --> 03:25:02,319
themselves uh i say recovery ships so

4145
03:25:06,630 --> 03:25:04,239
they're on your screen we have live

4146
03:25:09,110 --> 03:25:06,640
views coming to you from go navigator as

4147
03:25:11,269 --> 03:25:09,120
it is making its way to the designated

4148
03:25:12,229 --> 03:25:11,279
landing site off the coast of pensacola

4149
03:25:13,990 --> 03:25:12,239
florida

4150
03:25:15,110 --> 03:25:14,000
in the lower right hand side of your

4151
03:25:17,429 --> 03:25:15,120
screen

4152
03:25:20,150 --> 03:25:17,439
what you see there is the hydraulic lift

4153
03:25:22,309 --> 03:25:20,160
that will be used to hoist dragon out of

4154
03:25:24,469 --> 03:25:22,319
the water and into the nest which is

4155
03:25:26,389 --> 03:25:24,479
just barely out of view there

4156
03:25:29,030 --> 03:25:26,399
but that nest is what the capsule will

4157
03:25:30,710 --> 03:25:29,040
sit on and then be pulled more towards

4158
03:25:32,710 --> 03:25:30,720
the interior of the deck and that's

4159
03:25:34,790 --> 03:25:32,720
where we'll open the hatch and and have

4160
03:25:36,870 --> 03:25:34,800
bob and doug come out so as you can see

4161
03:25:38,309 --> 03:25:36,880
we got some blue skies with a couple of

4162
03:25:40,389 --> 03:25:38,319
clouds

4163
03:25:42,070 --> 03:25:40,399
it's a picture-perfect day those seas

4164
03:25:43,590 --> 03:25:42,080
look really calm

4165
03:25:45,110 --> 03:25:43,600
earlier the

4166
03:25:47,190 --> 03:25:45,120
the most recent

4167
03:25:49,590 --> 03:25:47,200
weather report indicated that we were

4168
03:25:53,030 --> 03:25:49,600
looking at about one mile per hour for

4169
03:25:54,710 --> 03:25:53,040
winds which is fantastic so it's great

4170
03:25:57,269 --> 03:25:54,720
to see those live views coming to us

4171
03:25:59,190 --> 03:25:57,279
from go navigator as it is making its

4172
03:26:00,630 --> 03:25:59,200
way towards the pensacola florida

4173
03:26:02,469 --> 03:26:00,640
recovery zone

4174
03:26:05,510 --> 03:26:02,479
yeah we you really couldn't have asked

4175
03:26:07,269 --> 03:26:05,520
for better weather than we got today

4176
03:26:09,349 --> 03:26:07,279
weather was the one thing we were really

4177
03:26:11,590 --> 03:26:09,359
keeping a close eye on as we marched

4178
03:26:12,790 --> 03:26:11,600
towards this splashdown today we had a

4179
03:26:14,550 --> 03:26:12,800
number of different checkpoints

4180
03:26:16,309 --> 03:26:14,560
throughout the week where nasa and

4181
03:26:18,309 --> 03:26:16,319
spacex were meeting assessing the

4182
03:26:20,469 --> 03:26:18,319
weather and our conditions where we had

4183
03:26:22,389 --> 03:26:20,479
to have not only our prime site with go

4184
03:26:24,790 --> 03:26:22,399
weather conditions but our alternate

4185
03:26:26,710 --> 03:26:24,800
site at least one alternate site as well

4186
03:26:29,030 --> 03:26:26,720
dragon does have the capability to

4187
03:26:31,510 --> 03:26:29,040
download to different alternate sites

4188
03:26:33,110 --> 03:26:31,520
once it's in free flight so

4189
03:26:35,830 --> 03:26:33,120
we just passed a checkpoint a few hours

4190
03:26:38,469 --> 03:26:35,840
ago where they locked in panama city as

4191
03:26:40,870 --> 03:26:38,479
the alternate site and we have seven

4192
03:26:42,309 --> 03:26:40,880
different landing zones around florida

4193
03:26:44,389 --> 03:26:42,319
three of them on the atlantic side

4194
03:26:46,870 --> 03:26:44,399
jacksonville daytona and the cape were

4195
03:26:48,150 --> 03:26:46,880
not in consideration for this weekend

4196
03:26:50,389 --> 03:26:48,160
as they are still dealing with the

4197
03:26:52,389 --> 03:26:50,399
tropical weather system but we're able

4198
03:26:54,469 --> 03:26:52,399
to get great weather at pensacola and

4199
03:26:57,510 --> 03:26:54,479
they're set up for that splashdown today

4200
03:26:59,110 --> 03:26:57,520
and go navigator is on its way it left

4201
03:27:02,229 --> 03:26:59,120
the port just about an hour and a half

4202
03:27:04,469 --> 03:27:02,239
ago and we've been following its

4203
03:27:07,349 --> 03:27:04,479
progress it had one of its backup

4204
03:27:09,030 --> 03:27:07,359
generators was failed and they were

4205
03:27:10,870 --> 03:27:09,040
working to replace it with another one

4206
03:27:13,030 --> 03:27:10,880
but weren't able to get it there in time

4207
03:27:15,429 --> 03:27:13,040
but that is not a constraint to do the

4208
03:27:17,510 --> 03:27:15,439
recovery operations go navigator still

4209
03:27:19,510 --> 03:27:17,520
perfectly capable of effectively and

4210
03:27:21,429 --> 03:27:19,520
safely recovering the capsule and bob

4211
03:27:23,269 --> 03:27:21,439
and doug from from the ocean in its

4212
03:27:24,710 --> 03:27:23,279
current state yeah

4213
03:27:26,150 --> 03:27:24,720
so like we mentioned before we are

4214
03:27:28,389 --> 03:27:26,160
taking your questions this morning

4215
03:27:31,269 --> 03:27:28,399
through twitter using the hashtag ask

4216
03:27:33,910 --> 03:27:31,279
nasa our next question comes to us from

4217
03:27:36,550 --> 03:27:33,920
jim he'd like to know what are all those

4218
03:27:37,510 --> 03:27:36,560
people in that room doing that's a great

4219
03:27:39,510 --> 03:27:37,520
question

4220
03:27:41,590 --> 03:27:39,520
that is mission control center here at

4221
03:27:44,550 --> 03:27:41,600
spacex headquarters in hawthorne

4222
03:27:47,269 --> 03:27:44,560
california there you see all of our

4223
03:27:49,030 --> 03:27:47,279
dragon operators and our mission

4224
03:27:50,150 --> 03:27:49,040
director so

4225
03:27:52,790 --> 03:27:50,160
those are the people that are

4226
03:27:55,510 --> 03:27:52,800
essentially continuing to monitor dragon

4227
03:27:58,309 --> 03:27:55,520
as i've mentioned before dragon is is

4228
03:28:00,550 --> 03:27:58,319
designed to fly itself autonomously

4229
03:28:03,750 --> 03:28:00,560
there are very few things that the folks

4230
03:28:05,670 --> 03:28:03,760
in that room have to command manually

4231
03:28:08,150 --> 03:28:05,680
but for those things it's a lot of data

4232
03:28:10,229 --> 03:28:08,160
review and verifying that the conditions

4233
03:28:11,670 --> 03:28:10,239
that need to be in place before sending

4234
03:28:13,349 --> 03:28:11,680
said commands

4235
03:28:15,670 --> 03:28:13,359
are achieved but those people are

4236
03:28:17,349 --> 03:28:15,680
essentially responsible for

4237
03:28:20,790 --> 03:28:17,359
monitoring the health and safety and

4238
03:28:22,870 --> 03:28:20,800
telemetry of our crew and capsule

4239
03:28:24,550 --> 03:28:22,880
yeah mission controls are just a part of

4240
03:28:27,269 --> 03:28:24,560
human space flight

4241
03:28:29,510 --> 03:28:27,279
this one has been in the game ever since

4242
03:28:30,950 --> 03:28:29,520
dragon launched while dragon was docked

4243
03:28:32,870 --> 03:28:30,960
to the international space station it

4244
03:28:34,710 --> 03:28:32,880
was powered down for a lot of its time

4245
03:28:36,309 --> 03:28:34,720
there but they would still come in

4246
03:28:38,229 --> 03:28:36,319
occasionally to wake dragon up do a

4247
03:28:38,950 --> 03:28:38,239
bunch of checkouts and we did a number

4248
03:28:41,030 --> 03:28:38,960
of

4249
03:28:42,630 --> 03:28:41,040
different tests while dragon was docked

4250
03:28:45,429 --> 03:28:42,640
to the international space station this

4251
03:28:47,030 --> 03:28:45,439
was just another chance to see how it

4252
03:28:50,070 --> 03:28:47,040
integrated into the overall station

4253
03:28:52,469 --> 03:28:50,080
system as we were passing both energy

4254
03:28:54,229 --> 03:28:52,479
electrical power and data to and from

4255
03:28:55,510 --> 03:28:54,239
dragon while it was docked

4256
03:28:58,229 --> 03:28:55,520
bob and doug and a couple of their

4257
03:29:00,309 --> 03:28:58,239
expedition 63 crew members also doing a

4258
03:29:02,070 --> 03:29:00,319
habitability study as again this is a

4259
03:29:04,950 --> 03:29:02,080
test flight so we did a bunch of

4260
03:29:06,469 --> 03:29:04,960
demonstration flights on the way up to

4261
03:29:08,790 --> 03:29:06,479
the station with bob duck manually

4262
03:29:10,389 --> 03:29:08,800
controlling the dragon spacecraft

4263
03:29:11,590 --> 03:29:10,399
and this habitability study was

4264
03:29:13,910 --> 03:29:11,600
something that they did while they were

4265
03:29:15,750 --> 03:29:13,920
on board i was largely

4266
03:29:17,349 --> 03:29:15,760
kind of just some

4267
03:29:19,990 --> 03:29:17,359
some spatial

4268
03:29:21,990 --> 03:29:20,000
tests where they were inside dragon they

4269
03:29:24,229 --> 03:29:22,000
practiced uh getting in and out of their

4270
03:29:26,229 --> 03:29:24,239
suits and doing leak checks and they had

4271
03:29:27,590 --> 03:29:26,239
two of their expedition 63 crew members

4272
03:29:29,030 --> 03:29:27,600
come and join them

4273
03:29:31,190 --> 03:29:29,040
so they could test out sleeping

4274
03:29:32,870 --> 03:29:31,200
arrangements for people in microgravity

4275
03:29:35,670 --> 03:29:32,880
in a dragon capsule so they're able to

4276
03:29:38,150 --> 03:29:35,680
do that just again to give teams some

4277
03:29:39,670 --> 03:29:38,160
real tangible this is how we're going to

4278
03:29:41,670 --> 03:29:39,680
do this when we're flying these full

4279
03:29:43,830 --> 03:29:41,680
operational crews with our first one

4280
03:29:45,110 --> 03:29:43,840
crew one coming up as early as the end

4281
03:29:47,349 --> 03:29:45,120
of september

4282
03:29:50,150 --> 03:29:47,359
yeah pretty exciting stuff

4283
03:29:51,750 --> 03:29:50,160
our next question comes to us from

4284
03:29:53,670 --> 03:29:51,760
ibrox baby

4285
03:29:56,150 --> 03:29:53,680
how do they get the hatch open once

4286
03:29:57,990 --> 03:29:56,160
dragon has splashed down and who will be

4287
03:30:00,150 --> 03:29:58,000
doing it

4288
03:30:02,469 --> 03:30:00,160
that is a good question so we won't be

4289
03:30:04,150 --> 03:30:02,479
opening the hatch until dragon is lifted

4290
03:30:06,070 --> 03:30:04,160
out of the water and placed onto the

4291
03:30:09,510 --> 03:30:06,080
recovery vessel

4292
03:30:10,469 --> 03:30:09,520
that hatch will be manually opened

4293
03:30:11,910 --> 03:30:10,479
we will

4294
03:30:14,710 --> 03:30:11,920
the flight surgeon will actually be the

4295
03:30:16,309 --> 03:30:14,720
first person to pop his head in

4296
03:30:17,349 --> 03:30:16,319
and say hi to bob and doug while they're

4297
03:30:19,590 --> 03:30:17,359
still

4298
03:30:21,910 --> 03:30:19,600
strapped in make sure they're feeling

4299
03:30:24,630 --> 03:30:21,920
okay that everything went well

4300
03:30:25,750 --> 03:30:24,640
and then we will

4301
03:30:27,750 --> 03:30:25,760
have them

4302
03:30:29,590 --> 03:30:27,760
unstrap and we'll help them exit from

4303
03:30:32,790 --> 03:30:29,600
the vehicle and then we'll have them go

4304
03:30:36,710 --> 03:30:32,800
into their medical tent for full medical

4305
03:30:39,269 --> 03:30:36,720
uh evaluation so a really good question

4306
03:30:41,670 --> 03:30:39,279
all right our next one comes from for

4307
03:30:43,269 --> 03:30:41,680
the love of tennis said when the shuttle

4308
03:30:47,990 --> 03:30:43,279
returned from space you could hear a

4309
03:30:49,750 --> 03:30:48,000
sonic boom will that happen with dragon

4310
03:30:51,830 --> 03:30:49,760
as far as i know no

4311
03:30:53,750 --> 03:30:51,840
that will not happen i don't believe but

4312
03:30:56,790 --> 03:30:53,760
i'm not entirely sure

4313
03:30:58,389 --> 03:30:56,800
i know that i don't nobody will likely

4314
03:30:59,990 --> 03:30:58,399
hear it if that does happen this time is

4315
03:31:03,269 --> 03:31:00,000
dragon's going to be passing over the

4316
03:31:04,630 --> 03:31:03,279
gulf uh for its entire descent

4317
03:31:06,870 --> 03:31:04,640
through that final

4318
03:31:09,110 --> 03:31:06,880
after deorbit burn and actually passing

4319
03:31:10,309 --> 03:31:09,120
through the earth's atmosphere so if it

4320
03:31:12,389 --> 03:31:10,319
happened it would happen out in the

4321
03:31:14,389 --> 03:31:12,399
middle of the gulf of mexico where it

4322
03:31:16,150 --> 03:31:14,399
would be very unlikely i'm not sure

4323
03:31:17,590 --> 03:31:16,160
though we'll have to we'll come back to

4324
03:31:19,830 --> 03:31:17,600
this one a little bit later and get you

4325
03:31:21,670 --> 03:31:19,840
an answer on that

4326
03:31:23,429 --> 03:31:21,680
um our next one comes from lakin who

4327
03:31:25,750 --> 03:31:23,439
wants to know will bob and doug be able

4328
03:31:28,070 --> 03:31:25,760
to feel splashdown or feel the capsule

4329
03:31:29,750 --> 03:31:28,080
rocking in the water

4330
03:31:31,910 --> 03:31:29,760
i think the answer to this is an

4331
03:31:33,590 --> 03:31:31,920
unequivocal yes yeah

4332
03:31:36,790 --> 03:31:33,600
they'll be touching down at about 16

4333
03:31:39,590 --> 03:31:36,800
miles an hour which is vastly slower

4334
03:31:41,830 --> 03:31:39,600
than that 17 500 miles an hour they're

4335
03:31:44,309 --> 03:31:41,840
going right now into orbit but still

4336
03:31:47,030 --> 03:31:44,319
enough that they'll feel a bit of a jolt

4337
03:31:48,469 --> 03:31:47,040
some of the soyuz landings which

4338
03:31:50,229 --> 03:31:48,479
might be a little bit rougher but those

4339
03:31:52,630 --> 03:31:50,239
use soft landing engines and a lot of

4340
03:31:54,710 --> 03:31:52,640
astronauts kind of compare those to

4341
03:31:56,150 --> 03:31:54,720
being almost like a minor car crash

4342
03:31:57,910 --> 03:31:56,160
because you are still

4343
03:31:59,670 --> 03:31:57,920
strapped into a seat

4344
03:32:01,429 --> 03:31:59,680
and then you're kind of

4345
03:32:03,190 --> 03:32:01,439
hitting into something so they'll

4346
03:32:04,790 --> 03:32:03,200
definitely feel that and

4347
03:32:06,790 --> 03:32:04,800
they have been talking about their

4348
03:32:09,590 --> 03:32:06,800
expectations for rocking in the water

4349
03:32:10,309 --> 03:32:09,600
they've been a little graphic at times

4350
03:32:12,070 --> 03:32:10,319
it's

4351
03:32:14,469 --> 03:32:12,080
what they think they might experience

4352
03:32:16,150 --> 03:32:14,479
with sea sickness once they get down

4353
03:32:17,670 --> 03:32:16,160
but as they've told us there's only one

4354
03:32:20,150 --> 03:32:17,680
way to find out but they're prepared for

4355
03:32:22,070 --> 03:32:20,160
it nonetheless yeah

4356
03:32:24,229 --> 03:32:22,080
given the fact that they have both flown

4357
03:32:26,389 --> 03:32:24,239
on shuttle missions previously and they

4358
03:32:28,790 --> 03:32:26,399
are both test pilots bob and doug have

4359
03:32:30,710 --> 03:32:28,800
gone through extensive physical training

4360
03:32:31,910 --> 03:32:30,720
uh for all of their missions including

4361
03:32:34,309 --> 03:32:31,920
this one

4362
03:32:36,229 --> 03:32:34,319
i have mentioned before that the g's

4363
03:32:39,190 --> 03:32:36,239
that we're expecting to encounter during

4364
03:32:41,510 --> 03:32:39,200
re-entry is around four g's we also saw

4365
03:32:42,870 --> 03:32:41,520
about four g's during the launch portion

4366
03:32:44,870 --> 03:32:42,880
of the mission

4367
03:32:46,309 --> 03:32:44,880
so this really shouldn't be anything too

4368
03:32:47,670 --> 03:32:46,319
different from what they've experienced

4369
03:32:49,670 --> 03:32:47,680
previously

4370
03:32:52,389 --> 03:32:49,680
for a point of reference to those of us

4371
03:32:54,389 --> 03:32:52,399
that haven't been to space there are

4372
03:32:57,269 --> 03:32:54,399
many roller coasters across the world

4373
03:32:58,870 --> 03:32:57,279
that deliver four g's or more in

4374
03:33:00,070 --> 03:32:58,880
throughout the ride or at one point or

4375
03:33:02,389 --> 03:33:00,080
another so

4376
03:33:04,870 --> 03:33:02,399
it's safe to say that 4gs might sound

4377
03:33:06,950 --> 03:33:04,880
like a lot for those of us that haven't

4378
03:33:09,429 --> 03:33:06,960
been to space it's actually just kind of

4379
03:33:11,429 --> 03:33:09,439
like a kind of a moderately intense

4380
03:33:13,590 --> 03:33:11,439
roller coaster so

4381
03:33:15,269 --> 03:33:13,600
we can expect that to they will feel the

4382
03:33:17,349 --> 03:33:15,279
they will feel the splashdown and they

4383
03:33:19,030 --> 03:33:17,359
will feel the rocking a little bit

4384
03:33:20,710 --> 03:33:19,040
if there are waves the most recent

4385
03:33:22,710 --> 03:33:20,720
weather report indicated that the waves

4386
03:33:24,630 --> 03:33:22,720
weren't going to be too bad so all in

4387
03:33:27,110 --> 03:33:24,640
all we are expecting it to be a pretty

4388
03:33:30,070 --> 03:33:27,120
comfortable touchdown for bob and doug

4389
03:33:32,790 --> 03:33:30,080
on their return to home to earth

4390
03:33:34,550 --> 03:33:32,800
our next question comes from terry and

4391
03:33:36,630 --> 03:33:34,560
his dog

4392
03:33:39,190 --> 03:33:36,640
at what speed will the capsule hit the

4393
03:33:42,389 --> 03:33:39,200
water great question so we are

4394
03:33:44,550 --> 03:33:42,399
anticipating about 15 or 16 miles per

4395
03:33:46,469 --> 03:33:44,560
hour uh will be the speed when the

4396
03:33:47,990 --> 03:33:46,479
capsule touches down

4397
03:33:49,910 --> 03:33:48,000
in the gulf of mexico like we said

4398
03:33:53,110 --> 03:33:49,920
before we're targeting just off the

4399
03:33:55,429 --> 03:33:53,120
coast of pensacola florida that is where

4400
03:33:58,870 --> 03:33:55,439
go navigator our recovery ship is in

4401
03:34:00,630 --> 03:33:58,880
route 2 and when the capsule is

4402
03:34:02,389 --> 03:34:00,640
re-entering the earth's atmosphere the

4403
03:34:05,269 --> 03:34:02,399
atmosphere itself is helping to slow it

4404
03:34:07,510 --> 03:34:05,279
down we will deploy fur we will deploy

4405
03:34:09,429 --> 03:34:07,520
parachutes to help further slow it down

4406
03:34:11,910 --> 03:34:09,439
and by the time it hits the top of the

4407
03:34:13,190 --> 03:34:11,920
ocean it's only going 15 or 16 miles per

4408
03:34:15,269 --> 03:34:13,200
hour

4409
03:34:17,510 --> 03:34:15,279
all right our next question comes from

4410
03:34:18,710 --> 03:34:17,520
ezekiel who asked one that i think a lot

4411
03:34:21,349 --> 03:34:18,720
of people are going to be thinking about

4412
03:34:23,590 --> 03:34:21,359
real soon how do we get to buy or how do

4413
03:34:26,150 --> 03:34:23,600
we get to buy tickets soon for traveling

4414
03:34:28,950 --> 03:34:26,160
to the international space station

4415
03:34:31,110 --> 03:34:28,960
that you know good timing um as that is

4416
03:34:33,750 --> 03:34:31,120
something we're looking at on the not in

4417
03:34:35,670 --> 03:34:33,760
the not too distant future uh nasa

4418
03:34:38,070 --> 03:34:35,680
recently committed to supporting at

4419
03:34:40,150 --> 03:34:38,080
least two private astronaut missions a

4420
03:34:42,229 --> 03:34:40,160
year to the international space station

4421
03:34:43,269 --> 03:34:42,239
there are a number of companies spacex

4422
03:34:46,070 --> 03:34:43,279
included

4423
03:34:48,630 --> 03:34:46,080
that have been working to kind of

4424
03:34:50,630 --> 03:34:48,640
develop the capability to fly private

4425
03:34:51,990 --> 03:34:50,640
citizens non-government astronauts into

4426
03:34:54,229 --> 03:34:52,000
space and potentially to the

4427
03:34:56,710 --> 03:34:54,239
international space station so i would

4428
03:34:58,070 --> 03:34:56,720
say definitely follow the industry

4429
03:34:59,750 --> 03:34:58,080
keep an eye out

4430
03:35:01,030 --> 03:34:59,760
the prices will likely be a little bit

4431
03:35:03,349 --> 03:35:01,040
high at first

4432
03:35:06,309 --> 03:35:03,359
especially for most of us but that

4433
03:35:08,950 --> 03:35:06,319
really is a major goal right now of a

4434
03:35:11,429 --> 03:35:08,960
lot of space travel is to try and open

4435
03:35:12,309 --> 03:35:11,439
it up to those who aren't necessarily

4436
03:35:13,510 --> 03:35:12,319
just

4437
03:35:15,510 --> 03:35:13,520
governments

4438
03:35:17,429 --> 03:35:15,520
space travel for so long has just been

4439
03:35:19,269 --> 03:35:17,439
the realm of governments who would have

4440
03:35:21,190 --> 03:35:19,279
the budgets to do these kinds of things

4441
03:35:22,389 --> 03:35:21,200
and we've seen

4442
03:35:24,630 --> 03:35:22,399
basically

4443
03:35:26,389 --> 03:35:24,640
an explosion of commercial activity in

4444
03:35:28,630 --> 03:35:26,399
low earth orbit the international space

4445
03:35:31,190 --> 03:35:28,640
station's been kind of the cornerstone

4446
03:35:33,110 --> 03:35:31,200
of enabling that entire market with a

4447
03:35:34,870 --> 03:35:33,120
marketplace and a capability for

4448
03:35:37,110 --> 03:35:34,880
research and transportation and a number

4449
03:35:39,190 --> 03:35:37,120
of other things and we work with a lot

4450
03:35:42,229 --> 03:35:39,200
of partners in the space industry to try

4451
03:35:43,670 --> 03:35:42,239
and just grow that even more yeah

4452
03:35:46,389 --> 03:35:43,680
another question comes to us from

4453
03:35:48,229 --> 03:35:46,399
twitter using the hashtag ask nasa this

4454
03:35:50,630 --> 03:35:48,239
one comes to us from chris

4455
03:35:52,550 --> 03:35:50,640
how airtight is the iss

4456
03:35:55,110 --> 03:35:52,560
well i think it's safe to say that the

4457
03:35:57,190 --> 03:35:55,120
iss the international space station is

4458
03:35:59,349 --> 03:35:57,200
completely airtight given the fact that

4459
03:36:02,229 --> 03:35:59,359
it is orbiting earth in the vacuum of

4460
03:36:04,550 --> 03:36:02,239
space uh it has to be airtight in order

4461
03:36:06,870 --> 03:36:04,560
to make sure that the crew is safe

4462
03:36:08,389 --> 03:36:06,880
throughout their stay on station

4463
03:36:10,950 --> 03:36:08,399
yeah it's

4464
03:36:12,870 --> 03:36:10,960
it is essentially airtight there is

4465
03:36:15,349 --> 03:36:12,880
enough that you will get a tiny little

4466
03:36:17,910 --> 03:36:15,359
bit of leak sometimes through seals

4467
03:36:19,510 --> 03:36:17,920
so it's never anything where you'll

4468
03:36:20,870 --> 03:36:19,520
be sucked up against the side of a hatch

4469
03:36:22,710 --> 03:36:20,880
or anything like that

4470
03:36:25,510 --> 03:36:22,720
but just because making something

4471
03:36:26,710 --> 03:36:25,520
perfectly vacuum proof is extremely hard

4472
03:36:28,469 --> 03:36:26,720
especially when you have so many

4473
03:36:30,550 --> 03:36:28,479
interconnecting parts that's why we do

4474
03:36:32,830 --> 03:36:30,560
occasionally have to inject additional

4475
03:36:35,670 --> 03:36:32,840
breathing gases into the space station

4476
03:36:38,309 --> 03:36:35,680
atmosphere we actually delivered them in

4477
03:36:40,389 --> 03:36:38,319
these super densified spheres

4478
03:36:43,190 --> 03:36:40,399
called norse tanks nitrogen oxygen

4479
03:36:45,590 --> 03:36:43,200
regeneration regeneration system

4480
03:36:47,510 --> 03:36:45,600
just to kind of top off the atmosphere

4481
03:36:49,429 --> 03:36:47,520
inside of the international space

4482
03:36:52,469 --> 03:36:49,439
station but great question

4483
03:36:56,389 --> 03:36:52,479
well let's do one more from andrea why

4484
03:36:58,150 --> 03:36:56,399
are spacecraft usually painted white

4485
03:36:58,950 --> 03:36:58,160
that is a good question

4486
03:37:00,710 --> 03:36:58,960
so

4487
03:37:02,870 --> 03:37:00,720
generally speaking a lot of it comes

4488
03:37:05,590 --> 03:37:02,880
down to preference

4489
03:37:08,150 --> 03:37:05,600
all spacex vehicles are operational

4490
03:37:11,429 --> 03:37:08,160
vehicles are black and white of course

4491
03:37:12,710 --> 03:37:11,439
starship currently is silver

4492
03:37:14,389 --> 03:37:12,720
but as of right that's still in

4493
03:37:16,950 --> 03:37:14,399
development but all of our operational

4494
03:37:20,229 --> 03:37:16,960
vehicles are black or white

4495
03:37:22,550 --> 03:37:20,239
and in this case it just so happens that

4496
03:37:24,550 --> 03:37:22,560
in order to conform to that aesthetic

4497
03:37:25,990 --> 03:37:24,560
the paint that we use the thermal

4498
03:37:28,550 --> 03:37:26,000
protective paint

4499
03:37:31,110 --> 03:37:28,560
on top of those panels on the exterior

4500
03:37:33,590 --> 03:37:31,120
of the capsule we make it white

4501
03:37:35,510 --> 03:37:33,600
and a lot of other things are white

4502
03:37:38,150 --> 03:37:35,520
exactly for the reason kate just said is

4503
03:37:39,830 --> 03:37:38,160
those thermal properties when when

4504
03:37:42,150 --> 03:37:39,840
you're in outer space the only way you

4505
03:37:44,870 --> 03:37:42,160
can really heat up or absorb heat or

4506
03:37:48,309 --> 03:37:44,880
reject heat is through radiation

4507
03:37:50,070 --> 03:37:48,319
and if you are a black surface it's just

4508
03:37:51,990 --> 03:37:50,080
like down here on planet earth if you

4509
03:37:54,150 --> 03:37:52,000
wear a black shirt and you feel hotter

4510
03:37:55,510 --> 03:37:54,160
that's because your shirt is

4511
03:37:57,510 --> 03:37:55,520
basically absorbing more of that

4512
03:37:58,630 --> 03:37:57,520
infrared radiation so

4513
03:38:00,389 --> 03:37:58,640
to help

4514
03:38:02,870 --> 03:38:00,399
keep things cooler essentially you can

4515
03:38:04,150 --> 03:38:02,880
paint them white with these reflective

4516
03:38:06,229 --> 03:38:04,160
or very

4517
03:38:07,990 --> 03:38:06,239
low albedo coatings

4518
03:38:09,510 --> 03:38:08,000
and that can help maintain a better

4519
03:38:11,349 --> 03:38:09,520
thermal we have a lot of things we call

4520
03:38:13,269 --> 03:38:11,359
thermal blankets which are just

4521
03:38:14,469 --> 03:38:13,279
essentially white fabrics that will

4522
03:38:16,550 --> 03:38:14,479
cover up

4523
03:38:18,630 --> 03:38:16,560
metallic areas of the space station that

4524
03:38:20,070 --> 03:38:18,640
would otherwise get really hot

4525
03:38:22,389 --> 03:38:20,080
in direct sunlight that you can keep

4526
03:38:23,830 --> 03:38:22,399
cool just with that white color

4527
03:38:25,429 --> 03:38:23,840
great question though

4528
03:38:28,389 --> 03:38:25,439
again we are taking your questions

4529
03:38:30,710 --> 03:38:28,399
through the hashtag asknasa on twitter

4530
03:38:32,950 --> 03:38:30,720
so be sure to continue to submit those

4531
03:38:34,710 --> 03:38:32,960
we'll try to get to as many as we can

4532
03:38:36,469 --> 03:38:34,720
throughout the morning

4533
03:38:38,630 --> 03:38:36,479
and for now we're just going to continue

4534
03:38:41,590 --> 03:38:38,640
to watch bob and doug as they zip around

4535
03:38:43,830 --> 03:38:41,600
planet earth we are a little less than

4536
03:38:45,670 --> 03:38:43,840
three hours away now from things really

4537
03:38:48,150 --> 03:38:45,680
starting to pick up we're going to be

4538
03:38:49,670 --> 03:38:48,160
looking for all of those events that we

4539
03:38:51,590 --> 03:38:49,680
talked through starting with that trunk

4540
03:38:53,750 --> 03:38:51,600
separation coming up soon and

4541
03:38:58,269 --> 03:38:53,760
everything's still on track for a

4542
03:59:51,349 --> 03:38:58,279
splashdown today at 11 48 a.m pacific

4543
04:00:06,830 --> 03:59:53,590
drag in spacex for four decimal seven

4544
04:00:12,309 --> 04:00:10,229
zero go ahead spacex

4545
04:00:14,389 --> 04:00:12,319
okay doug we're just uh a couple minutes

4546
04:00:17,110 --> 04:00:14,399
into the uh planned suit donning time i

4547
04:00:19,910 --> 04:00:17,120
wanted to give you guys a go for all

4548
04:00:21,750 --> 04:00:19,920
sections of four decimal 700 orbit

4549
04:00:27,830 --> 04:00:21,760
preparation we are standing by to

4550
04:00:33,030 --> 04:00:30,950
okay copy that we are through

4551
04:00:35,349 --> 04:00:33,040
uh

4552
04:00:38,389 --> 04:00:35,359
section three and we'll report the

4553
04:00:41,030 --> 04:00:38,399
status of the uh

4554
04:00:42,950 --> 04:00:41,040
inventory here in a few minutes and uh

4555
04:00:45,110 --> 04:00:42,960
copy go for soup donning and just as a

4556
04:00:47,110 --> 04:00:45,120
status for that we are in our comfort

4557
04:00:49,269 --> 04:00:47,120
garments and our orthostatic garments

4558
04:00:52,630 --> 04:00:49,279
and uh we have started the fluid loading

4559
04:00:56,710 --> 04:00:55,189
okay spacex copies uh we'll listen up

4560
04:00:58,630 --> 04:00:56,720
for that inventory in a few minutes and

4561
04:01:00,229 --> 04:00:58,640
you got your comfort garments or the

4562
04:01:15,510 --> 04:01:00,239
static garments and have started fluid

4563
04:01:15,520 --> 04:01:19,830
okay

4564
04:01:24,630 --> 04:01:21,910
all right so we just heard a call up to

4565
04:01:26,550 --> 04:01:24,640
the crew as they're getting into

4566
04:01:27,990 --> 04:01:26,560
uh some of their activities to get ready

4567
04:01:30,229 --> 04:01:28,000
for this deorbit burn so they're about

4568
04:01:32,150 --> 04:01:30,239
to get suited up we heard they're in

4569
04:01:34,389 --> 04:01:32,160
their comfort garments so those are

4570
04:01:35,830 --> 04:01:34,399
essentially the black athletic clothes

4571
04:01:37,510 --> 04:01:35,840
that they're going to wear is the base

4572
04:01:39,670 --> 04:01:37,520
layer underneath their suits they're

4573
04:01:41,349 --> 04:01:39,680
also in what they called orthostatic

4574
04:01:43,830 --> 04:01:41,359
garments and those are essentially

4575
04:01:45,750 --> 04:01:43,840
compression pants or compression shorts

4576
04:01:47,189 --> 04:01:45,760
that they're wearing and that helps to

4577
04:01:48,469 --> 04:01:47,199
kind of squeeze

4578
04:01:50,469 --> 04:01:48,479
uh or

4579
04:01:53,189 --> 04:01:50,479
that helps to kind of increase the blood

4580
04:01:55,110 --> 04:01:53,199
flow as they're going to be going from

4581
04:01:57,750 --> 04:01:55,120
all of the fluids and they're being up

4582
04:01:59,990 --> 04:01:57,760
around their head uh to being back in a

4583
04:02:01,349 --> 04:02:00,000
gravity situation where you're your

4584
04:02:02,790 --> 04:02:01,359
your blood everything kind of pulls

4585
04:02:05,189 --> 04:02:02,800
around your legs just due to the pull of

4586
04:02:06,630 --> 04:02:05,199
gravity these garments kind of squeeze

4587
04:02:09,990 --> 04:02:06,640
the legs and force some of that blood

4588
04:02:12,469 --> 04:02:10,000
back up so it's not as kind of a jarring

4589
04:02:14,870 --> 04:02:12,479
of a transition from the fluid shift

4590
04:02:16,790 --> 04:02:14,880
happening so they're doing that to

4591
04:02:19,510 --> 04:02:16,800
prepare for their re-adaptation to

4592
04:02:21,510 --> 04:02:19,520
gravity also doing fluid loading which

4593
04:02:23,429 --> 04:02:21,520
has been just shown to help with

4594
04:02:24,229 --> 04:02:23,439
orthostatic intolerance

4595
04:02:26,710 --> 04:02:24,239
so

4596
04:02:29,510 --> 04:02:26,720
essentially they won't feel as

4597
04:02:31,990 --> 04:02:29,520
dizzy or disoriented once they get back

4598
04:02:34,469 --> 04:02:32,000
down it helps by actually increasing the

4599
04:02:38,070 --> 04:02:34,479
amount of plasma in the blood even

4600
04:02:39,910 --> 04:02:38,080
for once they uh re-enter gravity so all

4601
04:02:41,910 --> 04:02:39,920
that going on board right now on dragon

4602
04:02:43,110 --> 04:02:41,920
yeah so it's exciting to hear that they

4603
04:02:45,349 --> 04:02:43,120
are beginning

4604
04:02:47,189 --> 04:02:45,359
the beginning to enter the last phases

4605
04:02:50,229 --> 04:02:47,199
that they as crew members need to

4606
04:02:52,630 --> 04:02:50,239
complete prior to re-entry

4607
04:02:55,110 --> 04:02:52,640
we're about two hours and 20 minutes

4608
04:02:57,349 --> 04:02:55,120
away from the next physical milestone in

4609
04:02:59,349 --> 04:02:57,359
terms of the vehicle itself

4610
04:03:00,550 --> 04:02:59,359
will have what's known as claw

4611
04:03:03,110 --> 04:03:00,560
separation

4612
04:03:05,189 --> 04:03:03,120
and that's where the mechanism that

4613
04:03:07,910 --> 04:03:05,199
basically contains the umbilicals for

4614
04:03:10,870 --> 04:03:07,920
power and telemetry and fluids

4615
04:03:13,269 --> 04:03:10,880
between the trunk and the capsule we

4616
04:03:15,830 --> 04:03:13,279
will separate that in order to allow us

4617
04:03:17,349 --> 04:03:15,840
to jettison the trunk by doing so the

4618
04:03:20,469 --> 04:03:17,359
heat shield of the capsule will be

4619
04:03:22,389 --> 04:03:20,479
exposed and allowing dragon to be

4620
04:03:25,510 --> 04:03:22,399
ready for re-entry

4621
04:03:28,229 --> 04:03:25,520
a couple minutes after we jettison

4622
04:03:29,990 --> 04:03:28,239
the trunk away from the capsule uh we

4623
04:03:33,110 --> 04:03:30,000
will then maneuver the capsule into a

4624
04:03:35,510 --> 04:03:33,120
position to allow for it to perform the

4625
04:03:38,070 --> 04:03:35,520
deorbit burn this will be the burn that

4626
04:03:40,389 --> 04:03:38,080
places dragon on its final trajectory we

4627
04:03:42,790 --> 04:03:40,399
are aiming for the gulf of mexico today

4628
04:03:45,590 --> 04:03:42,800
specifically off the coast of pensacola

4629
04:03:47,510 --> 04:03:45,600
florida is our designated landing zone

4630
04:03:49,269 --> 04:03:47,520
uh after

4631
04:03:51,990 --> 04:03:49,279
the deorbit burn completes which we're

4632
04:03:53,189 --> 04:03:52,000
expecting that to be about 11 and a half

4633
04:03:55,590 --> 04:03:53,199
minutes

4634
04:03:57,750 --> 04:03:55,600
we will then close the nose cone and

4635
04:04:00,070 --> 04:03:57,760
lock it and then a couple minutes after

4636
04:04:01,670 --> 04:04:00,080
that completes we'll begin to re-enter

4637
04:04:04,229 --> 04:04:01,680
the earth's atmosphere and things will

4638
04:04:05,750 --> 04:04:04,239
start to get pretty hot

4639
04:04:07,429 --> 04:04:05,760
yeah and

4640
04:04:09,670 --> 04:04:07,439
everything is going to be standing by in

4641
04:04:11,349 --> 04:04:09,680
the recovery zone once they're done with

4642
04:04:12,950 --> 04:04:11,359
that de-orbit burn that re-entry through

4643
04:04:14,950 --> 04:04:12,960
the earth's atmosphere and eventually

4644
04:04:17,590 --> 04:04:14,960
landing under parachutes this is a live

4645
04:04:21,030 --> 04:04:17,600
view from the go navigator which still

4646
04:04:23,830 --> 04:04:21,040
making its way out to the recovery zone

4647
04:04:25,830 --> 04:04:23,840
it left port just a few hours ago

4648
04:04:28,389 --> 04:04:25,840
just about

4649
04:04:30,710 --> 04:04:28,399
two hours and ten minutes ago

4650
04:04:32,710 --> 04:04:30,720
making its way out from pensacola to the

4651
04:04:34,309 --> 04:04:32,720
anticipated splashdown zone it's going

4652
04:04:36,229 --> 04:04:34,319
to be on station about three nautical

4653
04:04:38,469 --> 04:04:36,239
miles away from the anticipated

4654
04:04:40,710 --> 04:04:38,479
splashdown site at which point it'll

4655
04:04:42,070 --> 04:04:40,720
take it just around 30 minutes to close

4656
04:04:43,269 --> 04:04:42,080
in on the capsule following the

4657
04:04:45,429 --> 04:04:43,279
splashdown

4658
04:04:46,870 --> 04:04:45,439
as we did discuss earlier that was

4659
04:04:49,030 --> 04:04:46,880
pretty much the only issue that had come

4660
04:04:52,070 --> 04:04:49,040
up so far today was with a backup

4661
04:04:53,990 --> 04:04:52,080
generator on the go navigator they were

4662
04:04:56,469 --> 04:04:54,000
not able to get a replacement one on

4663
04:04:58,870 --> 04:04:56,479
board in time but all the flight rules

4664
04:05:01,189 --> 04:04:58,880
still enable us to go through with this

4665
04:05:03,670 --> 04:05:01,199
operation go navigator with its primary

4666
04:05:07,349 --> 04:05:03,680
generator still fully capable of

4667
04:05:09,429 --> 04:05:07,359
affecting a recovery this morning

4668
04:05:12,590 --> 04:05:09,439
yeah so that recovery time we're looking

4669
04:05:15,189 --> 04:05:12,600
at 11 48 am pacific

4670
04:05:17,030 --> 04:05:15,199
1848 universal

4671
04:05:19,269 --> 04:05:17,040
so if you want to take a nap you have a

4672
04:05:20,389 --> 04:05:19,279
couple of hours before the action really

4673
04:05:22,070 --> 04:05:20,399
kicks in

4674
04:05:23,110 --> 04:05:22,080
but we will continue to be bringing you

4675
04:05:25,030 --> 04:05:23,120
coverage

4676
04:05:26,790 --> 04:05:25,040
throughout the entire mission

4677
04:05:28,950 --> 04:05:26,800
hopefully we'll have some more great

4678
04:05:32,150 --> 04:05:28,960
views from go navigator our recovery

4679
04:05:34,710 --> 04:05:32,160
ship making its way to the uh splashdown

4680
04:05:37,590 --> 04:05:34,720
location like we said before the

4681
04:05:39,269 --> 04:05:37,600
recovery vessel is currently carrying

4682
04:05:41,110 --> 04:05:39,279
about 40 people

4683
04:05:43,830 --> 04:05:41,120
they all have it's actually a

4684
04:05:47,189 --> 04:05:43,840
combination of spacex and nasa people

4685
04:05:48,790 --> 04:05:47,199
they all have specific jobs and whenever

4686
04:05:50,870 --> 04:05:48,800
we are actually performing the recovery

4687
04:05:52,790 --> 04:05:50,880
operations you only see a small handful

4688
04:05:56,070 --> 04:05:52,800
of those individuals on board because

4689
04:05:57,990 --> 04:05:56,080
safety is the top priority not only for

4690
04:05:59,830 --> 04:05:58,000
bob and doug but also for the personnel

4691
04:06:03,030 --> 04:05:59,840
on board so we'll make sure that

4692
04:06:04,870 --> 04:06:03,040
unnecessary personnel will be away and

4693
04:06:06,950 --> 04:06:04,880
in one of the

4694
04:06:09,189 --> 04:06:06,960
one of the back rooms whereas the

4695
04:06:10,870 --> 04:06:09,199
operational deck during active recovery

4696
04:06:13,030 --> 04:06:10,880
mission during active recovery

4697
04:06:15,269 --> 04:06:13,040
operations we'll have those key

4698
04:06:16,790 --> 04:06:15,279
personnel involved and we will be able

4699
04:06:18,229 --> 04:06:16,800
to see

4700
04:06:19,510 --> 04:06:18,239
the descent all the way through

4701
04:06:21,750 --> 04:06:19,520
splashdown

4702
04:06:23,349 --> 04:06:21,760
as well as the fast boat approach so

4703
04:06:25,189 --> 04:06:23,359
those are the two smaller boats that

4704
04:06:27,269 --> 04:06:25,199
make their way to dragon after it

4705
04:06:29,510 --> 04:06:27,279
splashes down they're the ones that are

4706
04:06:32,309 --> 04:06:29,520
doing the initial preparation of the

4707
04:06:34,950 --> 04:06:32,319
capsule preparing it to be lifted out of

4708
04:06:37,110 --> 04:06:34,960
the water and onto the recovery vessel

4709
04:06:38,309 --> 04:06:37,120
so we have quite a bit coming up and

4710
04:06:40,070 --> 04:06:38,319
we're looking forward to being able to

4711
04:06:42,469 --> 04:06:40,080
show you all of that

4712
04:06:44,950 --> 04:06:42,479
as i've mentioned before the recovery

4713
04:06:47,590 --> 04:06:44,960
team is a newer one here at spacex since

4714
04:06:50,229 --> 04:06:47,600
you know the whole crew recovery process

4715
04:06:51,910 --> 04:06:50,239
is newer and it's really cool that we

4716
04:06:53,910 --> 04:06:51,920
get to showcase them a little bit the

4717
04:06:57,590 --> 04:06:53,920
last time we were able to do so was

4718
04:06:59,990 --> 04:06:57,600
about a year ago year and a half almost

4719
04:07:01,590 --> 04:07:00,000
on the demo one mission so

4720
04:07:03,590 --> 04:07:01,600
be sure to stay tuned throughout the

4721
04:07:05,030 --> 04:07:03,600
entire recovery process because once the

4722
04:07:07,510 --> 04:07:05,040
capsule is lifted up and out of the

4723
04:07:09,990 --> 04:07:07,520
water and is secured to the deck of the

4724
04:07:11,830 --> 04:07:10,000
ship that will be our first opportunity

4725
04:07:13,590 --> 04:07:11,840
to hopefully get a couple thumbs up from

4726
04:07:15,670 --> 04:07:13,600
bob and doug indicating that they're

4727
04:07:17,750 --> 04:07:15,680
feeling good after their return yeah we

4728
04:07:19,830 --> 04:07:17,760
expect it to take about an hour from

4729
04:07:21,750 --> 04:07:19,840
splashdown to them getting out of the

4730
04:07:23,429 --> 04:07:21,760
capsule a lot of it will be those

4731
04:07:25,590 --> 04:07:23,439
initial checks happening in the opening

4732
04:07:27,670 --> 04:07:25,600
minutes following splashdown and it'll

4733
04:07:30,229 --> 04:07:27,680
take about 30 minutes for the primary

4734
04:07:32,950 --> 04:07:30,239
vessel the go navigator to get very

4735
04:07:34,950 --> 04:07:32,960
close to the dragon capsule itself and

4736
04:07:37,189 --> 04:07:34,960
then once it's there it'll take only a

4737
04:07:39,349 --> 04:07:37,199
few more minutes to lift it up onto the

4738
04:07:41,750 --> 04:07:39,359
boat and then move it on that nest

4739
04:07:43,510 --> 04:07:41,760
towards the crew recovery platform so

4740
04:07:45,510 --> 04:07:43,520
it's a platform

4741
04:07:47,590 --> 04:07:45,520
with enough space for just a couple of

4742
04:07:49,269 --> 04:07:47,600
people underneath the helipad

4743
04:07:51,510 --> 04:07:49,279
onboard the go navigator where they'll

4744
04:07:53,349 --> 04:07:51,520
be able to open up the hatch spacex is a

4745
04:07:54,870 --> 04:07:53,359
neil menon one of the flight surgeons

4746
04:07:56,469 --> 04:07:54,880
that works here is going to be the first

4747
04:07:58,309 --> 04:07:56,479
one through the hatch he'll do a quick

4748
04:08:00,070 --> 04:07:58,319
check on bob and doug

4749
04:08:01,830 --> 04:08:00,080
making sure they're ready to come out

4750
04:08:03,830 --> 04:08:01,840
and then we'll be assisting them out of

4751
04:08:05,910 --> 04:08:03,840
the capsule and immediately over into a

4752
04:08:07,349 --> 04:08:05,920
medical facility on board

4753
04:08:09,269 --> 04:08:07,359
they'll be on there for just a little

4754
04:08:11,189 --> 04:08:09,279
while and then we'll look to land a

4755
04:08:13,349 --> 04:08:11,199
helicopter on board

4756
04:08:16,149 --> 04:08:13,359
the the ship and then they'll catch a

4757
04:08:17,830 --> 04:08:16,159
quick flight back to pensacola yeah so

4758
04:08:20,149 --> 04:08:17,840
after that they'll also then be

4759
04:08:21,990 --> 04:08:20,159
transplanted by air airplane

4760
04:08:22,870 --> 04:08:22,000
back to houston after they complete

4761
04:08:25,670 --> 04:08:22,880
those

4762
04:08:27,030 --> 04:08:25,680
checkouts at the pensacola naval

4763
04:08:29,510 --> 04:08:27,040
air station

4764
04:08:32,149 --> 04:08:29,520
and they'll then the the best part of

4765
04:08:33,830 --> 04:08:32,159
the day family reunions so i'm sure bob

4766
04:08:36,630 --> 04:08:33,840
and doug are looking forward to being

4767
04:08:39,590 --> 04:08:36,640
able to give their family hugs again in

4768
04:08:41,670 --> 04:08:39,600
less than 24 hours if you were tuned in

4769
04:08:43,830 --> 04:08:41,680
earlier in the webcast you may have

4770
04:08:46,469 --> 04:08:43,840
caught the special wake-up message sent

4771
04:08:49,030 --> 04:08:46,479
to bob and doug to bring them out of

4772
04:08:51,990 --> 04:08:49,040
their sleep phase it was

4773
04:08:54,389 --> 04:08:52,000
nothing short of precious and adorable a

4774
04:08:56,790 --> 04:08:54,399
message from both of their sons they

4775
04:08:59,110 --> 04:08:56,800
each have one son and it was a nice

4776
04:09:02,070 --> 04:08:59,120
little audio recording saying daddy wake

4777
04:09:03,590 --> 04:09:02,080
up wake up wake up so i highly encourage

4778
04:09:06,389 --> 04:09:03,600
you to check it out because

4779
04:09:09,269 --> 04:09:06,399
it is certainly heartwarming and quite a

4780
04:09:10,790 --> 04:09:09,279
special opportunity to be able to share

4781
04:09:13,189 --> 04:09:10,800
a moment like that

4782
04:09:14,550 --> 04:09:13,199
with their family from far away

4783
04:09:15,990 --> 04:09:14,560
they were pretty adamant it's a good

4784
04:09:17,349 --> 04:09:16,000
thing we have weather because it sounds

4785
04:09:18,950 --> 04:09:17,359
like those kids are expecting their

4786
04:09:20,309 --> 04:09:18,960
dad's home today

4787
04:09:23,349 --> 04:09:20,319
i think one of them's got to go get a

4788
04:09:25,590 --> 04:09:23,359
dog so he's excited what it sounds like

4789
04:09:27,510 --> 04:09:25,600
but everything's gone extremely smoothly

4790
04:09:29,910 --> 04:09:27,520
with dragon's flight it all started

4791
04:09:32,309 --> 04:09:29,920
yesterday on saturday when they loaded

4792
04:09:34,710 --> 04:09:32,319
in and departed the international space

4793
04:09:36,950 --> 04:09:34,720
station since then we've had a series of

4794
04:09:39,110 --> 04:09:36,960
steps all executed flawlessly we haven't

4795
04:09:41,030 --> 04:09:39,120
had any issues tracked with dragon

4796
04:09:43,349 --> 04:09:41,040
during the departure

4797
04:09:45,510 --> 04:09:43,359
and the setup for splashdown again today

4798
04:09:47,830 --> 04:09:45,520
this is our prime location

4799
04:09:50,950 --> 04:09:47,840
this is our prime opportunity so once we

4800
04:09:53,189 --> 04:09:50,960
undock from station dragon had

4801
04:09:54,950 --> 04:09:53,199
an identified prime and a backup the

4802
04:09:56,550 --> 04:09:54,960
alternate which was

4803
04:09:58,950 --> 04:09:56,560
several days later

4804
04:10:01,429 --> 04:09:58,960
if we were unable to land today

4805
04:10:03,590 --> 04:10:01,439
we would target a different site 48

4806
04:10:05,510 --> 04:10:03,600
hours later it's actually about 47 hours

4807
04:10:07,590 --> 04:10:05,520
from the initial splashdown target to

4808
04:10:09,670 --> 04:10:07,600
the secondary and that secondary was

4809
04:10:10,550 --> 04:10:09,680
locked in a few hours ago as panama city

4810
04:10:11,910 --> 04:10:10,560
but

4811
04:10:14,229 --> 04:10:11,920
everything's looking great with the

4812
04:10:16,469 --> 04:10:14,239
weather today as we talked through we

4813
04:10:18,469 --> 04:10:16,479
were we had constraints of about 10

4814
04:10:19,269 --> 04:10:18,479
miles an hour for the wind

4815
04:10:20,950 --> 04:10:19,279
and

4816
04:10:23,110 --> 04:10:20,960
our initial weather report last night we

4817
04:10:25,110 --> 04:10:23,120
were about a mile an hour and

4818
04:10:26,870 --> 04:10:25,120
we just got upgraded to about two miles

4819
04:10:29,110 --> 04:10:26,880
an hour

4820
04:10:30,389 --> 04:10:29,120
winds have doubled but when you go from

4821
04:10:33,030 --> 04:10:30,399
one to two miles an hour we're still

4822
04:10:34,950 --> 04:10:33,040
well within the limits um so still

4823
04:10:36,630 --> 04:10:34,960
looking forward to an on time and a good

4824
04:10:38,630 --> 04:10:36,640
splashdown today yeah the other good

4825
04:10:41,189 --> 04:10:38,640
news coming out of that most recent red

4826
04:10:43,030 --> 04:10:41,199
most recent weather report

4827
04:10:44,550 --> 04:10:43,040
is that the waves are also looking

4828
04:10:45,349 --> 04:10:44,560
really calm

4829
04:10:51,910 --> 04:10:45,359
the

4830
04:10:54,710 --> 04:10:51,920
how frequently so

4831
04:10:57,110 --> 04:10:54,720
waves occur in this type of pattern and

4832
04:10:59,750 --> 04:10:57,120
you know for safety reasons we can't

4833
04:11:01,510 --> 04:10:59,760
have high waves or waves at a certain

4834
04:11:04,229 --> 04:11:01,520
height occurring very frequently that

4835
04:11:06,149 --> 04:11:04,239
makes recovery operations dangerous

4836
04:11:08,070 --> 04:11:06,159
and we're pleased to report that the

4837
04:11:09,830 --> 04:11:08,080
last uh information that we got

4838
04:11:13,030 --> 04:11:09,840
regarding the weather anticipated at

4839
04:11:14,309 --> 04:11:13,040
splashdown are very small waves i i've

4840
04:11:16,950 --> 04:11:14,319
been pulled up here real quick it was

4841
04:11:19,910 --> 04:11:16,960
something like uh yeah here we go

4842
04:11:21,990 --> 04:11:19,920
just half a foot occurring every six

4843
04:11:24,870 --> 04:11:22,000
seconds so you can basically think of it

4844
04:11:26,469 --> 04:11:24,880
as if your ocean baseline is here every

4845
04:11:28,550 --> 04:11:26,479
six seconds your

4846
04:11:30,950 --> 04:11:28,560
ocean if your ocean baseline is here

4847
04:11:31,830 --> 04:11:30,960
you're every six seconds your wave comes

4848
04:11:34,710 --> 04:11:31,840
up

4849
04:11:36,550 --> 04:11:34,720
a half a foot every six seconds so

4850
04:11:38,710 --> 04:11:36,560
really calm so it's really glad we're

4851
04:11:40,710 --> 04:11:38,720
really happy to see that uh while

4852
04:11:44,229 --> 04:11:40,720
unfortunately the weather and the

4853
04:11:46,630 --> 04:11:44,239
atlantic ocean landing zones um wasn't

4854
04:11:48,630 --> 04:11:46,640
really cooperating we're very happy to

4855
04:11:52,149 --> 04:11:48,640
report that the anticipated weather for

4856
04:11:53,429 --> 04:11:52,159
splashdown today is going to be mild and

4857
04:11:55,349 --> 04:11:53,439
based on the views that we were seeing

4858
04:11:57,510 --> 04:11:55,359
from go navigator earlier quite the

4859
04:12:00,149 --> 04:11:57,520
picture-perfect day yeah and weather is

4860
04:12:01,510 --> 04:12:00,159
something that we track very closely if

4861
04:12:04,149 --> 04:12:01,520
you've been following the mission since

4862
04:12:05,750 --> 04:12:04,159
may you know weather was definitely in

4863
04:12:07,189 --> 04:12:05,760
the conversation back when we launched

4864
04:12:08,710 --> 04:12:07,199
where we had to scrub the first attempt

4865
04:12:10,550 --> 04:12:08,720
just due to some bad weather that moved

4866
04:12:12,070 --> 04:12:10,560
into the area but we're able to just

4867
04:12:13,990 --> 04:12:12,080
kind of pinpoint right between some

4868
04:12:16,790 --> 04:12:14,000
clouds for that second launch attempt on

4869
04:12:19,269 --> 04:12:16,800
may 30th and then we were watching it

4870
04:12:21,670 --> 04:12:19,279
extremely closely today too

4871
04:12:23,269 --> 04:12:21,680
or even in the lead up to where we are

4872
04:12:24,790 --> 04:12:23,279
today and we're going to continue to

4873
04:12:26,550 --> 04:12:24,800
have weather checkpoints all the way up

4874
04:12:28,309 --> 04:12:26,560
until about an hour and a half before

4875
04:12:31,030 --> 04:12:28,319
landing that's really the final

4876
04:12:32,469 --> 04:12:31,040
opportunity we have to wave off

4877
04:12:34,870 --> 04:12:32,479
and we actually have a question from

4878
04:12:37,429 --> 04:12:34,880
twitter just a reminder use the

4879
04:12:38,790 --> 04:12:37,439
ask nasa on twitter and we'll try to get

4880
04:12:40,630 --> 04:12:38,800
to your question throughout the morning

4881
04:12:42,630 --> 04:12:40,640
and this one from demi wanted to know if

4882
04:12:46,149 --> 04:12:42,640
the splashdown were to be scrubbed could

4883
04:12:48,070 --> 04:12:46,159
dragon go back to iss or could they be

4884
04:12:50,710 --> 04:12:48,080
in the orbit on their own

4885
04:12:52,630 --> 04:12:50,720
for this mission we don't have a plan

4886
04:12:54,469 --> 04:12:52,640
essentially to re-rendezvous with the

4887
04:12:56,229 --> 04:12:54,479
international space station we weren't

4888
04:12:57,910 --> 04:12:56,239
going to undock until we had good

4889
04:13:00,149 --> 04:12:57,920
weather at a prime and alternate

4890
04:13:01,189 --> 04:13:00,159
location both were go at the time that

4891
04:13:03,830 --> 04:13:01,199
we left

4892
04:13:05,510 --> 04:13:03,840
so if for some reason we had to wave off

4893
04:13:08,149 --> 04:13:05,520
within the next hour or so from

4894
04:13:10,070 --> 04:13:08,159
pensacola dragon would continue in its

4895
04:13:12,790 --> 04:13:10,080
orbit it would make some adjustments

4896
04:13:15,590 --> 04:13:12,800
over the next 47 hours and then we would

4897
04:13:18,070 --> 04:13:15,600
target a splashdown at panama city we

4898
04:13:21,590 --> 04:13:18,080
had to lock in that

4899
04:13:23,269 --> 04:13:21,600
that alternate site just a few hours ago

4900
04:13:26,710 --> 04:13:23,279
up until that point for the first about

4901
04:13:28,550 --> 04:13:26,720
15 or about the first 12 hours or so

4902
04:13:29,910 --> 04:13:28,560
dragon has the ability to change

4903
04:13:31,670 --> 04:13:29,920
alternate sites so we could have

4904
04:13:33,269 --> 04:13:31,680
targeted one of the other gulf sites out

4905
04:13:34,469 --> 04:13:33,279
potentially even going back to pensacola

4906
04:13:35,910 --> 04:13:34,479
on the second

4907
04:13:38,389 --> 04:13:35,920
two days later

4908
04:13:40,870 --> 04:13:38,399
but we were able to lock in panama city

4909
04:13:42,790 --> 04:13:40,880
and i'm not anticipating to need that

4910
04:13:45,590 --> 04:13:42,800
but dragon does have the ability to wave

4911
04:13:47,590 --> 04:13:45,600
off and kind of re-attempt a splashdown

4912
04:13:49,429 --> 04:13:47,600
two days later yeah as we mentioned

4913
04:13:52,070 --> 04:13:49,439
earlier dragon will be will be

4914
04:13:55,269 --> 04:13:52,080
performing a deorbit burn that'll last

4915
04:13:57,189 --> 04:13:55,279
11 and a half minutes that deorbit burn

4916
04:13:59,429 --> 04:13:57,199
is the moment where we are sending

4917
04:14:01,429 --> 04:13:59,439
dragon on its final trajectory to the

4918
04:14:03,910 --> 04:14:01,439
landing zone that deorbit burn

4919
04:14:06,229 --> 04:14:03,920
maneuvering is performed a little bit

4920
04:14:08,469 --> 04:14:06,239
less than an hour prior to splashdown

4921
04:14:11,110 --> 04:14:08,479
itself so like dan said definitely

4922
04:14:12,550 --> 04:14:11,120
continuing to monitor weather until

4923
04:14:13,990 --> 04:14:12,560
you know the very last moment that we

4924
04:14:16,630 --> 04:14:14,000
can but there is a little bit of

4925
04:14:19,670 --> 04:14:16,640
flexibility there in terms of if we have

4926
04:14:22,070 --> 04:14:19,680
to wave off for 24 or 48 hours bob and

4927
04:14:24,469 --> 04:14:22,080
doug would remain in the capsule all

4928
04:14:26,710 --> 04:14:24,479
right our next question comes from cody

4929
04:14:29,830 --> 04:14:26,720
von o'brien who wanted to know what were

4930
04:14:33,189 --> 04:14:29,840
bob and doug doing in space

4931
04:14:34,710 --> 04:14:33,199
well they spent 62 days on board the

4932
04:14:37,830 --> 04:14:34,720
international space station as crew

4933
04:14:40,149 --> 04:14:37,840
members of expedition 63 and they were

4934
04:14:42,469 --> 04:14:40,159
fully fledged crew members so they kind

4935
04:14:44,550 --> 04:14:42,479
of did the full gamut of space station

4936
04:14:47,269 --> 04:14:44,560
operations they did everything from

4937
04:14:49,990 --> 04:14:47,279
executing science contributing more than

4938
04:14:51,990 --> 04:14:50,000
100 hours of their time

4939
04:14:53,750 --> 04:14:52,000
executing science experiments on board

4940
04:14:56,229 --> 04:14:53,760
from pretty much every discipline we

4941
04:14:57,750 --> 04:14:56,239
have on their biology to technology

4942
04:14:59,590 --> 04:14:57,760
demonstrations

4943
04:15:02,710 --> 04:14:59,600
to just learning more about the human

4944
04:15:05,830 --> 04:15:02,720
body and how it adapts to space flight

4945
04:15:07,990 --> 04:15:05,840
bob bankin was part of four spacewalks

4946
04:15:10,309 --> 04:15:08,000
along with chris cassidy the two of them

4947
04:15:12,790 --> 04:15:10,319
both now have ten spacewalks in their

4948
04:15:14,630 --> 04:15:12,800
careers ties them with mike lopez

4949
04:15:16,469 --> 04:15:14,640
alegria and peggy whitson as the most

4950
04:15:18,149 --> 04:15:16,479
for u.s astronauts

4951
04:15:19,670 --> 04:15:18,159
so they were they were extremely busy

4952
04:15:21,750 --> 04:15:19,680
while they were on the space station i

4953
04:15:24,469 --> 04:15:21,760
know chris cassidy was happy to have

4954
04:15:26,309 --> 04:15:24,479
some help on board as it's just been him

4955
04:15:28,309 --> 04:15:26,319
and his two russian cosmonauts for the

4956
04:15:30,070 --> 04:15:28,319
last several months and they're kind of

4957
04:15:31,590 --> 04:15:30,080
back in that situation now and that's

4958
04:15:34,469 --> 04:15:31,600
why we're really looking forward to crew

4959
04:15:36,229 --> 04:15:34,479
one coming up this fall yeah days on the

4960
04:15:37,830 --> 04:15:36,239
international space station in addition

4961
04:15:39,269 --> 04:15:37,840
to spacewalks

4962
04:15:41,990 --> 04:15:39,279
and

4963
04:15:44,229 --> 04:15:42,000
performing science experiments you also

4964
04:15:46,550 --> 04:15:44,239
have to eat you have to sleep and you

4965
04:15:49,110 --> 04:15:46,560
have to exercise so

4966
04:15:51,110 --> 04:15:49,120
it's really easy to see how whenever

4967
04:15:53,269 --> 04:15:51,120
there are only a couple of people on the

4968
04:15:54,630 --> 04:15:53,279
international space station that things

4969
04:15:56,630 --> 04:15:54,640
that are

4970
04:15:59,590 --> 04:15:56,640
you know exercise eating and sleeping

4971
04:16:02,870 --> 04:15:59,600
are absolutely essential exercise helps

4972
04:16:05,349 --> 04:16:02,880
to keep the body strong and

4973
04:16:07,910 --> 04:16:05,359
try to prevent the effects of

4974
04:16:08,630 --> 04:16:07,920
that microgravity has on the human body

4975
04:16:11,910 --> 04:16:08,640
so

4976
04:16:14,309 --> 04:16:11,920
when it comes to what might get shifted

4977
04:16:16,149 --> 04:16:14,319
out a little bit it's not exercise it's

4978
04:16:18,070 --> 04:16:16,159
not eating it's not sleeping and so

4979
04:16:19,910 --> 04:16:18,080
having two extra hands on board to

4980
04:16:21,990 --> 04:16:19,920
assist with things like spacewalk and

4981
04:16:24,309 --> 04:16:22,000
spacebox and being able to perform some

4982
04:16:25,990 --> 04:16:24,319
of the science on board uh was was

4983
04:16:27,990 --> 04:16:26,000
definitely a help but in addition to

4984
04:16:30,070 --> 04:16:28,000
that bob and doug were also completing

4985
04:16:31,590 --> 04:16:30,080
mission objectives related to demo 2

4986
04:16:33,670 --> 04:16:31,600
while it was docked you know making sure

4987
04:16:35,990 --> 04:16:33,680
that the battery life was as expected

4988
04:16:38,389 --> 04:16:36,000
making sure that the solar panels were

4989
04:16:42,389 --> 04:16:38,399
still absorbing and generating power as

4990
04:16:44,469 --> 04:16:42,399
expected so uh it they've i i am sure

4991
04:16:47,269 --> 04:16:44,479
that uh by the time that they get home

4992
04:16:49,110 --> 04:16:47,279
they will be pretty tired not just from

4993
04:16:51,269 --> 04:16:49,120
you know the dynamic events happening

4994
04:16:53,349 --> 04:16:51,279
today but just from the last two months

4995
04:16:55,750 --> 04:16:53,359
as a whole i you know i'm getting tired

4996
04:16:57,189 --> 04:16:55,760
just thinking about it ready for a

4997
04:16:58,550 --> 04:16:57,199
all right our next question comes from

4998
04:17:00,710 --> 04:16:58,560
philip hartman who wants to know how

4999
04:17:02,469 --> 04:17:00,720
much training does it take to be able to

5000
04:17:04,630 --> 04:17:02,479
operate control

5001
04:17:06,870 --> 04:17:04,640
all of the technology on dragon and the

5002
04:17:08,710 --> 04:17:06,880
things on space station

5003
04:17:10,790 --> 04:17:08,720
i can touch on the space station stuff

5004
04:17:12,630 --> 04:17:10,800
we typically train crew members for

5005
04:17:14,630 --> 04:17:12,640
about two years

5006
04:17:15,670 --> 04:17:14,640
we've had a couple that

5007
04:17:17,189 --> 04:17:15,680
kind of

5008
04:17:19,349 --> 04:17:17,199
cram in that training a little bit

5009
04:17:21,510 --> 04:17:19,359
shorter than that but typically crew

5010
04:17:23,670 --> 04:17:21,520
members get assigned about two years out

5011
04:17:25,750 --> 04:17:23,680
and spend that entire time training just

5012
04:17:27,910 --> 04:17:25,760
to do day-to-day tasks onboard the space

5013
04:17:30,950 --> 04:17:27,920
station i mean that's everything from

5014
04:17:32,790 --> 04:17:30,960
just operating the basic facilities uh

5015
04:17:34,469 --> 04:17:32,800
learning how to repair all of the major

5016
04:17:36,229 --> 04:17:34,479
pieces of hardware like the thing that

5017
04:17:38,950 --> 04:17:36,239
generates your oxygen or scrubs the

5018
04:17:40,950 --> 04:17:38,960
carbon dioxide how the water recycling

5019
04:17:42,550 --> 04:17:40,960
system works they get kind of crash

5020
04:17:43,910 --> 04:17:42,560
courses and operating a bunch of

5021
04:17:46,389 --> 04:17:43,920
different science hardware that's

5022
04:17:47,830 --> 04:17:46,399
onboard the space station it's it's you

5023
04:17:49,590 --> 04:17:47,840
kind of have to become a jack of all

5024
04:17:51,590 --> 04:17:49,600
trades when you're up there because one

5025
04:17:54,870 --> 04:17:51,600
day you're a mechanic the next day

5026
04:17:56,950 --> 04:17:54,880
you're a physicist the next day you're

5027
04:17:58,389 --> 04:17:56,960
spacewalking and so they they get a

5028
04:17:59,910 --> 04:17:58,399
whole bunch of training that they have

5029
04:18:02,149 --> 04:17:59,920
to take

5030
04:18:03,990 --> 04:18:02,159
and it's done all over the world too

5031
04:18:06,790 --> 04:18:04,000
yeah definitely can't call a handyman

5032
04:18:08,070 --> 04:18:06,800
when something goes wrong you are the

5033
04:18:10,630 --> 04:18:08,080
handyman

5034
04:18:13,349 --> 04:18:10,640
the next question comes to us from abby

5035
04:18:15,670 --> 04:18:13,359
again this is the hashtag asknasa

5036
04:18:18,630 --> 04:18:15,680
on twitter this may be a silly question

5037
04:18:21,189 --> 04:18:18,640
but is there a telescope on the iss that

5038
04:18:22,550 --> 04:18:21,199
the crew can use they don't have a

5039
04:18:24,229 --> 04:18:22,560
telescope

5040
04:18:26,950 --> 04:18:24,239
they don't actually have very many

5041
04:18:29,110 --> 04:18:26,960
windows that look up at the stars

5042
04:18:30,950 --> 04:18:29,120
we have a number of science experiments

5043
04:18:33,750 --> 04:18:30,960
that are on the international space

5044
04:18:35,910 --> 04:18:33,760
station that use its position outside of

5045
04:18:38,149 --> 04:18:35,920
the earth's atmosphere to to look kind

5046
04:18:40,070 --> 04:18:38,159
of beyond our solar system

5047
04:18:41,429 --> 04:18:40,080
we have some that aren't necessarily

5048
04:18:43,510 --> 04:18:41,439
telescopes

5049
04:18:45,030 --> 04:18:43,520
but like the alpha magnetic spectrometer

5050
04:18:46,149 --> 04:18:45,040
which is looking for signs of dark

5051
04:18:48,630 --> 04:18:46,159
matter

5052
04:18:51,030 --> 04:18:48,640
and then we have one that was a japanese

5053
04:18:53,670 --> 04:18:51,040
payload the name is escaping me but it

5054
04:18:55,349 --> 04:18:53,680
was essentially looking for pulsars

5055
04:18:57,830 --> 04:18:55,359
throughout the universe

5056
04:19:00,070 --> 04:18:57,840
and was really cool it was

5057
04:19:02,950 --> 04:19:00,080
essentially developing a futuristic

5058
04:19:05,349 --> 04:19:02,960
version of gps where it was looking to

5059
04:19:07,349 --> 04:19:05,359
develop a system or a map where you

5060
04:19:09,510 --> 04:19:07,359
could use pulsars some of the brightest

5061
04:19:10,870 --> 04:19:09,520
objects in the universe

5062
04:19:12,870 --> 04:19:10,880
to navigate

5063
04:19:14,469 --> 04:19:12,880
and obviously that's not something we

5064
04:19:16,149 --> 04:19:14,479
need to worry about right now because

5065
04:19:18,790 --> 04:19:16,159
we're not leaving our solar system

5066
04:19:20,469 --> 04:19:18,800
anytime soon but we're already learning

5067
04:19:22,389 --> 04:19:20,479
how to do that and we're using the

5068
04:19:23,910 --> 04:19:22,399
international space station to do it

5069
04:19:25,590 --> 04:19:23,920
they have some big lenses for their

5070
04:19:28,389 --> 04:19:25,600
cameras but those are pretty much

5071
04:19:31,189 --> 04:19:28,399
pointed back down towards earth

5072
04:19:33,189 --> 04:19:31,199
our next question wanted to know how

5073
04:19:35,269 --> 04:19:33,199
does the communication to dragon work is

5074
04:19:37,269 --> 04:19:35,279
it done through satellites

5075
04:19:39,510 --> 04:19:37,279
partially yes

5076
04:19:41,510 --> 04:19:39,520
if you think about the international

5077
04:19:43,990 --> 04:19:41,520
space station orbiting earth it

5078
04:19:46,790 --> 04:19:44,000
technically is considered a satellite as

5079
04:19:49,349 --> 04:19:46,800
well as a spaceship really big one yeah

5080
04:19:51,110 --> 04:19:49,359
and then we also have ground stations uh

5081
04:19:53,349 --> 04:19:51,120
across the world that are able to

5082
04:19:54,309 --> 04:19:53,359
provide uplinks and downlinks from the

5083
04:19:57,830 --> 04:19:54,319
station

5084
04:19:59,830 --> 04:19:57,840
as well as from dragon capsule itself so

5085
04:20:02,309 --> 04:19:59,840
we try to make all of those connections

5086
04:20:05,269 --> 04:20:02,319
as direct as possible to

5087
04:20:07,510 --> 04:20:05,279
us here in mission control you know for

5088
04:20:09,830 --> 04:20:07,520
trying to reduce latency and making sure

5089
04:20:11,510 --> 04:20:09,840
that we get high quality feeds so we try

5090
04:20:12,630 --> 04:20:11,520
to avoid ping-ponging as much as

5091
04:20:14,309 --> 04:20:12,640
possible

5092
04:20:16,710 --> 04:20:14,319
but yeah there there are a number of

5093
04:20:18,950 --> 04:20:16,720
ways uh but generally speaking we go

5094
04:20:21,189 --> 04:20:18,960
from capsule to ground in as short of a

5095
04:20:22,790 --> 04:20:21,199
distance as possible

5096
04:20:24,149 --> 04:20:22,800
all right our next one comes from juliet

5097
04:20:26,710 --> 04:20:24,159
who wants to know does nasa have a

5098
04:20:28,710 --> 04:20:26,720
full-size mock-up of the space station

5099
04:20:30,389 --> 04:20:28,720
in a training facility

5100
04:20:32,149 --> 04:20:30,399
we have several

5101
04:20:34,950 --> 04:20:32,159
actually

5102
04:20:36,950 --> 04:20:34,960
we have a building called the space

5103
04:20:38,710 --> 04:20:36,960
vehicle mock-up facility

5104
04:20:41,030 --> 04:20:38,720
in at the johnson space center in

5105
04:20:43,750 --> 04:20:41,040
houston where we have a full-size

5106
04:20:45,590 --> 04:20:43,760
mock-up of every single habitable module

5107
04:20:48,070 --> 04:20:45,600
so that's essentially saying every

5108
04:20:50,149 --> 04:20:48,080
single module you can actually go inside

5109
04:20:52,469 --> 04:20:50,159
there's a huge part of the space station

5110
04:20:54,630 --> 04:20:52,479
itself that's just external that isn't

5111
04:20:57,269 --> 04:20:54,640
pressurized and the astronauts only

5112
04:20:59,990 --> 04:20:57,279
really see when they're space walking so

5113
04:21:01,910 --> 04:21:00,000
to familiarize them with that part we

5114
04:21:03,510 --> 04:21:01,920
have a full-size mock-up in the bottom

5115
04:21:05,990 --> 04:21:03,520
of our swimming pool the neutral

5116
04:21:08,229 --> 04:21:06,000
buoyancy laboratory a 40-foot deep pool

5117
04:21:10,870 --> 04:21:08,239
they practice how to spacewalk so we

5118
04:21:12,710 --> 04:21:10,880
have several and they're typically of

5119
04:21:14,710 --> 04:21:12,720
kind of different fidelity is what we

5120
04:21:17,510 --> 04:21:14,720
call them so you'll have some that have

5121
04:21:19,590 --> 04:21:17,520
real racks real science hardware real

5122
04:21:21,349 --> 04:21:19,600
you know oxygen generation system built

5123
04:21:22,469 --> 04:21:21,359
in and then you'll have some that are

5124
04:21:24,229 --> 04:21:22,479
just kind of

5125
04:21:25,910 --> 04:21:24,239
representative of them they'll be full

5126
04:21:29,030 --> 04:21:25,920
size but they might have

5127
04:21:31,110 --> 04:21:29,040
uh like a printed poster of what's on

5128
04:21:33,590 --> 04:21:31,120
the wall here but you can still use

5129
04:21:35,590 --> 04:21:33,600
things like that for emergency training

5130
04:21:37,349 --> 04:21:35,600
we we really try to do as much training

5131
04:21:40,309 --> 04:21:37,359
on the ground and i know we do the same

5132
04:21:41,990 --> 04:21:40,319
in dragon in something that's lifelike

5133
04:21:43,750 --> 04:21:42,000
for what they're about to be

5134
04:21:45,750 --> 04:21:43,760
flying on once they're in space so by

5135
04:21:48,710 --> 04:21:45,760
the time they get there a lot of your

5136
04:21:50,550 --> 04:21:48,720
actions just feel like reflex

5137
04:21:54,149 --> 04:21:50,560
so at this point we're gonna check in on

5138
04:21:55,670 --> 04:21:54,159
dragon looks like it is about to go over

5139
04:21:57,510 --> 04:21:55,680
eastern europe

5140
04:21:59,349 --> 04:21:57,520
uh we're gonna

5141
04:22:01,030 --> 04:21:59,359
show our uh

5142
04:22:03,830 --> 04:22:01,040
ground track here and allow you to

5143
04:22:07,030 --> 04:22:03,840
follow along uh we still have let me

5144
04:22:09,670 --> 04:22:07,040
check my timer here

5145
04:22:11,189 --> 04:22:09,680
we still have two hours and one minute

5146
04:22:13,189 --> 04:22:11,199
until our

5147
04:22:15,189 --> 04:22:13,199
major milestone

5148
04:22:16,790 --> 04:22:15,199
begins that will be the claw separation

5149
04:22:19,590 --> 04:22:16,800
and preparation

5150
04:22:21,910 --> 04:22:19,600
to uh jettison the trunk again that's

5151
04:22:25,990 --> 04:22:21,920
coming up in two hours in one minute at

5152
04:22:27,670 --> 04:22:26,000
10 51 a.m pacific or 1851

5153
04:22:30,790 --> 04:22:27,680
universal so

5154
04:28:08,790 --> 04:22:30,800
stay with us and enjoy watching dragon

5155
04:28:15,750 --> 04:28:11,590
spacex dragon for inventory after fluid

5156
04:28:26,469 --> 04:28:17,990
okay spacex is ready to copy fluid

5157
04:28:33,429 --> 04:28:29,670
okay from location 10 uh two additional

5158
04:28:36,870 --> 04:28:33,439
bottles were consumed from 20s bag 207

5159
04:28:41,030 --> 04:28:36,880
and one from bag 206.

5160
04:28:45,510 --> 04:28:41,040
so that leaves a 208 empty 207 empty and

5161
04:28:49,149 --> 04:28:47,670
from location nine three bottles were

5162
04:28:51,110 --> 04:28:49,159
consumed from

5163
04:29:05,110 --> 04:28:51,120
203

5164
04:29:10,710 --> 04:29:07,030
okay thanks for the update looks like

5165
04:29:12,550 --> 04:29:10,720
bag 207 consumed two bottles 206

5166
04:29:15,830 --> 04:29:12,560
consumed one bottle

5167
04:29:19,030 --> 04:29:15,840
208 207 are empty and 206 has two

5168
04:29:23,750 --> 04:29:19,040
remaining and then from location 9 we

5169
04:29:29,750 --> 04:29:26,309
2 bottles from 203 i believe and that

5170
04:29:41,750 --> 04:29:29,760
means 203 and 204 empty the rest per

5171
04:29:47,269 --> 04:29:43,510
from location 9

5172
04:29:48,610 --> 04:29:47,279
203 and 204 are empty and everything

5173
04:29:52,870 --> 04:29:48,620
else is per the packing plan

5174
04:29:58,309 --> 04:29:55,830
okay copy location 9 correction 203 and

5175
04:30:09,269 --> 04:29:58,319
204 empty the rest in location 9 for the

5176
04:30:12,790 --> 04:30:11,349
and uh just one more sanity check bob

5177
04:30:23,750 --> 04:30:12,800
could you just tell us the total number

5178
04:30:36,950 --> 04:30:26,389
let me try to see the math from my notes

5179
04:30:43,429 --> 04:30:39,269
i believe since departing station we've

5180
04:30:46,630 --> 04:30:43,439
consumed 13 bottles

5181
04:30:47,910 --> 04:30:46,640
okay copy 13 bottles we'll reconcile our

5182
04:30:49,349 --> 04:30:47,920
records down here and let you know if we

5183
04:31:01,269 --> 04:30:49,359
got any questions

5184
04:31:04,550 --> 04:31:03,750
thanks solo and we're about to close out

5185
04:31:07,030 --> 04:31:04,560
uh

5186
04:31:08,870 --> 04:31:07,040
locations nine and ten and be suited and

5187
04:31:11,750 --> 04:31:08,880
so it's uh

5188
04:31:13,990 --> 04:31:11,760
not going to be practical to go back and

5189
04:31:16,469 --> 04:31:14,000
re-inventory anything if there's any

5190
04:31:18,229 --> 04:31:16,479
questions after about uh three minutes

5191
04:31:20,510 --> 04:31:18,239
so

5192
04:31:21,750 --> 04:31:20,520
please let us know if you can early

5193
04:31:23,349 --> 04:31:21,760
[Music]

5194
04:31:25,189 --> 04:31:23,359
okay copy and actually we do have a

5195
04:31:26,149 --> 04:31:25,199
question for location

5196
04:31:29,349 --> 04:31:26,159
10

5197
04:32:15,429 --> 04:31:29,359
bag 206 can you please uh read back the

5198
04:32:19,990 --> 04:32:17,510
okay let me uh unstow that bag it looks

5199
04:32:22,070 --> 04:32:20,000
like uh i made a mistake i thought they

5200
04:32:24,550 --> 04:32:22,080
had three battles in each one and i just

5201
04:32:26,469 --> 04:32:24,560
reported one was removed we'll have to

5202
04:32:29,189 --> 04:32:26,479
unstow the bag to count the quantity

5203
04:32:30,870 --> 04:32:29,199
inside of 206.

5204
04:32:34,229 --> 04:32:30,880
we have a pretty good readout bob that

5205
04:32:36,149 --> 04:32:34,239
206 started at uh five bottles so if you

5206
04:32:46,070 --> 04:32:36,159
know you took two out of there we can

5207
04:32:50,710 --> 04:32:49,189
now from 206 we took a single bottle out

5208
04:32:52,309 --> 04:32:50,720
so let me

5209
04:33:34,470 --> 04:32:52,319
count them for you

5210
04:33:40,310 --> 04:33:37,029
and in location 206 there are four

5211
04:33:44,230 --> 04:33:42,551
okay four bottles remaining in 206 that

5212
04:42:27,910 --> 04:33:44,240
math makes better sense to us appreciate

5213
04:42:31,430 --> 04:42:29,830
all right well we are still just getting

5214
04:42:33,190 --> 04:42:31,440
closer and closer to things really

5215
04:42:35,590 --> 04:42:33,200
picking up as bob and doe get ready to

5216
04:42:37,590 --> 04:42:35,600
hit the final phase of their flight back

5217
04:42:39,110 --> 04:42:37,600
to earth in the end of this demo 2

5218
04:42:41,110 --> 04:42:39,120
mission still have a couple of

5219
04:42:42,788 --> 04:42:41,120
milestones to go but i mean everything

5220
04:42:45,670 --> 04:42:42,798
picked up when we departed the space

5221
04:42:48,628 --> 04:42:45,680
station yesterday and it's been a pretty

5222
04:42:51,830 --> 04:42:48,638
smooth ride so far so everything really

5223
04:42:53,750 --> 04:42:51,840
kicked off back on saturday as on their

5224
04:42:56,948 --> 04:42:53,760
62nd day on board the international

5225
04:42:59,270 --> 04:42:56,958
space station their 63rd day in space

5226
04:43:01,110 --> 04:42:59,280
baba doug began to get the capsule ready

5227
04:43:04,390 --> 04:43:01,120
for their ride home

5228
04:43:06,390 --> 04:43:04,400
everything picked up when they got all

5229
04:43:09,510 --> 04:43:06,400
of the final cargo into the dragon

5230
04:43:12,070 --> 04:43:09,520
capsule and then got themselves in

5231
04:43:13,750 --> 04:43:12,080
and then closed that hatch

5232
04:43:15,670 --> 04:43:13,760
crawling into the top hatch to the

5233
04:43:17,830 --> 04:43:15,680
dragon spacecraft getting suited up

5234
04:43:19,430 --> 04:43:17,840
shortly thereafter meanwhile on the

5235
04:43:21,990 --> 04:43:19,440
station side station commander chris

5236
04:43:24,070 --> 04:43:22,000
cassidy closed the a pass hatch creating

5237
04:43:25,910 --> 04:43:24,080
what is known as the vestibule a space

5238
04:43:28,550 --> 04:43:25,920
between the two hatches that would be

5239
04:43:31,270 --> 04:43:28,560
exposed to vacuum following undocking

5240
04:43:33,550 --> 04:43:31,280
then we use valves on the dragon side to

5241
04:43:35,910 --> 04:43:33,560
draw the air out of that vestibule in a

5242
04:43:37,910 --> 04:43:35,920
depressurization step

5243
04:43:39,750 --> 04:43:37,920
bringing it down to vacuum and getting

5244
04:43:42,390 --> 04:43:39,760
it ready for that eventual physical

5245
04:43:44,550 --> 04:43:42,400
separation or undocking

5246
04:43:47,430 --> 04:43:44,560
after that was complete the teams down

5247
04:43:49,270 --> 04:43:47,440
here on the ground both in mcc x right

5248
04:43:50,550 --> 04:43:49,280
behind us and hawthorne and in the

5249
04:43:52,628 --> 04:43:50,560
international space station flight

5250
04:43:54,550 --> 04:43:52,638
control room in houston did a go no go

5251
04:43:56,868 --> 04:43:54,560
for undocking making sure everything was

5252
04:43:58,310 --> 04:43:56,878
good with systems onboard dragon and the

5253
04:43:59,350 --> 04:43:58,320
health of the international space

5254
04:44:01,510 --> 04:43:59,360
station

5255
04:44:04,230 --> 04:44:01,520
following that go no go we had a

5256
04:44:06,310 --> 04:44:04,240
successful separation with dragon using

5257
04:44:08,948 --> 04:44:06,320
draco thrusters around its service

5258
04:44:10,550 --> 04:44:08,958
section to physically separate from the

5259
04:44:12,310 --> 04:44:10,560
international space station after hooks

5260
04:44:14,868 --> 04:44:12,320
had driven back they were holding it in

5261
04:44:17,190 --> 04:44:14,878
place it executed those two quick burns

5262
04:44:19,590 --> 04:44:17,200
then it was on to four departure burns

5263
04:44:21,430 --> 04:44:19,600
spread over a number of hours initially

5264
04:44:23,030 --> 04:44:21,440
taking dragon up and over the

5265
04:44:25,270 --> 04:44:23,040
international space station which

5266
04:44:27,270 --> 04:44:25,280
brought it behind and then after it

5267
04:44:30,470 --> 04:44:27,280
lowered its orbit beneath the station

5268
04:44:32,470 --> 04:44:30,480
eventually bringing it out in front

5269
04:44:34,708 --> 04:44:32,480
following all of those successful

5270
04:44:36,070 --> 04:44:34,718
departure burns it was just about time

5271
04:44:37,590 --> 04:44:36,080
for the crew

5272
04:44:39,430 --> 04:44:37,600
to get some sleep

5273
04:44:41,110 --> 04:44:39,440
and actually during their sleep period

5274
04:44:44,070 --> 04:44:41,120
we were able to do what's known as the

5275
04:44:46,230 --> 04:44:44,080
departure phasing burn uh it's a little

5276
04:44:48,868 --> 04:44:46,240
off in this timeline as it actually

5277
04:44:56,310 --> 04:44:48,878
switched in the final hours leading up

5278
04:45:02,230 --> 04:44:58,470
spacex we have you loud and clear for

5279
04:45:02,240 --> 04:45:07,030
i read you the same

5280
04:45:11,590 --> 04:45:09,590
just pausing that timeline as the crew

5281
04:45:12,868 --> 04:45:11,600
in their suit up steps they just did a

5282
04:45:15,430 --> 04:45:12,878
comp check

5283
04:45:17,350 --> 04:45:15,440
so they have communications run through

5284
04:45:19,030 --> 04:45:17,360
the umbilical in their seats directly

5285
04:45:20,550 --> 04:45:19,040
into their suits where they're able to

5286
04:45:23,190 --> 04:45:20,560
maintain that conversation with the

5287
04:45:24,788 --> 04:45:23,200
ground we heard a little bit of chatters

5288
04:45:27,030 --> 04:45:24,798
a few minutes ago as they were finishing

5289
04:45:28,628 --> 04:45:27,040
up that fluid loading again that's done

5290
04:45:31,990 --> 04:45:28,638
to help with

5291
04:45:34,788 --> 04:45:32,000
combating orthostatic intolerance and to

5292
04:45:35,830 --> 04:45:34,798
put it simply that's dizziness in most

5293
04:45:37,830 --> 04:45:35,840
people

5294
04:45:40,310 --> 04:45:37,840
fluid loading can actually help

5295
04:45:42,628 --> 04:45:40,320
your body react to

5296
04:45:44,868 --> 04:45:42,638
what's typically a rush of blood away

5297
04:45:47,270 --> 04:45:44,878
from the head once you get back down in

5298
04:45:48,788 --> 04:45:47,280
a gravity environment which can make you

5299
04:45:50,310 --> 04:45:48,798
extremely dizzy

5300
04:45:52,628 --> 04:45:50,320
so fluid loading you can actually up the

5301
04:45:54,550 --> 04:45:52,638
amount of plasma in your blood

5302
04:45:56,070 --> 04:45:54,560
and that just helps kind of minimize

5303
04:45:58,868 --> 04:45:56,080
that they're also wearing what's known

5304
04:46:00,550 --> 04:45:58,878
as an orthostatic garment

5305
04:46:02,948 --> 04:46:00,560
essentially compression pants that's

5306
04:46:04,788 --> 04:46:02,958
squeezing their legs and forcing some of

5307
04:46:06,948 --> 04:46:04,798
that fluid from the legs up towards the

5308
04:46:09,510 --> 04:46:06,958
upper part of their body so everything's

5309
04:46:11,910 --> 04:46:09,520
continuing to proceed they're suited up

5310
04:46:14,150 --> 04:46:11,920
inside dragon for the second time in the

5311
04:46:16,310 --> 04:46:14,160
last 24 hours as we get ready for this d

5312
04:46:18,310 --> 04:46:16,320
orbit yeah there on your screen you can

5313
04:46:20,708 --> 04:46:18,320
see a shot of our mission control center

5314
04:46:23,910 --> 04:46:20,718
here at spacex headquarters in hawthorne

5315
04:46:25,830 --> 04:46:23,920
california those folks there are our

5316
04:46:28,070 --> 04:46:25,840
dragon operators they are technical

5317
04:46:29,910 --> 04:46:28,080
experts that continue to monitor the

5318
04:46:30,948 --> 04:46:29,920
data and telemetry coming down from

5319
04:46:32,628 --> 04:46:30,958
dragon

5320
04:46:34,708 --> 04:46:32,638
not only about the vehicle but of the

5321
04:46:36,628 --> 04:46:34,718
crew themselves continuing to make sure

5322
04:46:39,990 --> 04:46:36,638
that everything is going well and just

5323
04:46:41,510 --> 04:46:40,000
making sure that we are green or go to

5324
04:46:43,670 --> 04:46:41,520
step into

5325
04:46:46,390 --> 04:46:43,680
the next major milestones that we have

5326
04:46:49,110 --> 04:46:46,400
coming up uh at this point we're about

5327
04:46:51,670 --> 04:46:49,120
an hour and a half away from that

5328
04:46:53,830 --> 04:46:51,680
those milestones will begin with the

5329
04:46:56,948 --> 04:46:53,840
claw separation which is when we

5330
04:46:59,190 --> 04:46:56,958
initiate the the jettison of the trunk

5331
04:47:00,708 --> 04:46:59,200
in order to expose the heat shield

5332
04:47:04,550 --> 04:47:00,718
underneath the capsule

5333
04:47:06,948 --> 04:47:04,560
we need to let the trunk uh go away so

5334
04:47:10,310 --> 04:47:06,958
we separate the two that trunk will

5335
04:47:12,390 --> 04:47:10,320
actually reenter the earth's at

5336
04:47:14,390 --> 04:47:12,400
excuse me the

5337
04:47:16,230 --> 04:47:14,400
the trunk will actually re-enter the

5338
04:47:18,708 --> 04:47:16,240
earth's atmosphere and it'll

5339
04:47:20,310 --> 04:47:18,718
disintegrate upon doing so oh we got our

5340
04:47:21,910 --> 04:47:20,320
nice little animation back here so i'll

5341
04:47:23,670 --> 04:47:21,920
toss it back over to dan yeah we did

5342
04:47:25,750 --> 04:47:23,680
that departure phasing burn that's what

5343
04:47:27,750 --> 04:47:25,760
really kind of set us up on our pathway

5344
04:47:29,270 --> 04:47:27,760
towards where we are today and then the

5345
04:47:31,750 --> 04:47:29,280
crew did have a sleep period is again

5346
04:47:33,350 --> 04:47:31,760
this is about a 19-hour phasing or a

5347
04:47:35,430 --> 04:47:33,360
19-hour trip

5348
04:47:37,030 --> 04:47:35,440
from the station to the splashdown and

5349
04:47:39,430 --> 04:47:37,040
then as kate was saying it was on the

5350
04:47:42,628 --> 04:47:39,440
were almost up to claw and trunk

5351
04:47:44,390 --> 04:47:42,638
separation yeah so at 10 51 a.m pacific

5352
04:47:45,510 --> 04:47:44,400
or 1851

5353
04:47:47,510 --> 04:47:45,520
united

5354
04:47:49,430 --> 04:47:47,520
time or universal time we will have that

5355
04:47:51,590 --> 04:47:49,440
claw and trunk separation which like i

5356
04:47:54,310 --> 04:47:51,600
said before will basically allow us to

5357
04:47:57,270 --> 04:47:54,320
expose the heat shield and prepare us to

5358
04:47:59,750 --> 04:47:57,280
execute the deorbit burn the deorbit

5359
04:48:01,670 --> 04:47:59,760
burn is intended to place dragon on its

5360
04:48:03,670 --> 04:48:01,680
final trajectory to its landing zone

5361
04:48:05,350 --> 04:48:03,680
which as we have mentioned before it's

5362
04:48:08,070 --> 04:48:05,360
determined to be off the coast of

5363
04:48:11,030 --> 04:48:08,080
pensacola florida the dewar burn will

5364
04:48:13,830 --> 04:48:11,040
last about 11 and a half minutes after

5365
04:48:17,110 --> 04:48:13,840
doing so we will close and lock the nose

5366
04:48:18,868 --> 04:48:17,120
cone we do this in order to protect the

5367
04:48:20,470 --> 04:48:18,878
forward hatch located there at the top

5368
04:48:22,390 --> 04:48:20,480
of the capsule

5369
04:48:24,868 --> 04:48:22,400
and we do that after the deorbit burn

5370
04:48:27,910 --> 04:48:24,878
because the thruster is located there in

5371
04:48:29,910 --> 04:48:27,920
the forward bulkhead are what we use to

5372
04:48:33,190 --> 04:48:29,920
actually perform the deorbit burn so

5373
04:48:35,510 --> 04:48:33,200
once that nose close cone is closed we

5374
04:48:37,590 --> 04:48:35,520
enter a six minute long communication

5375
04:48:39,750 --> 04:48:37,600
blackout this is because we are

5376
04:48:41,750 --> 04:48:39,760
re-entering the atmosphere as we

5377
04:48:43,350 --> 04:48:41,760
encounter that atmosphere and friction

5378
04:48:46,230 --> 04:48:43,360
builds up plasma builds up on the

5379
04:48:48,470 --> 04:48:46,240
external sides of the capsule

5380
04:48:50,708 --> 04:48:48,480
creating a barrier essentially where we

5381
04:48:52,550 --> 04:48:50,718
can't command the capsule or receive

5382
04:48:55,190 --> 04:48:52,560
telemetry however dragon is completely

5383
04:48:56,070 --> 04:48:55,200
autonomous so totally fine it's driving

5384
04:49:00,948 --> 04:48:56,080
itself

5385
04:49:02,868 --> 04:49:00,958
anyway so uh we will then that like i

5386
04:49:04,788 --> 04:49:02,878
said that blackout period lasts for six

5387
04:49:07,350 --> 04:49:04,798
minutes a couple minutes after that we

5388
04:49:10,310 --> 04:49:07,360
will deploy the drogue parachutes drug

5389
04:49:13,270 --> 04:49:10,320
parachutes are used to for a couple of

5390
04:49:15,110 --> 04:49:13,280
reasons one to help slow the

5391
04:49:16,708 --> 04:49:15,120
vehicle down further before we deploy

5392
04:49:18,868 --> 04:49:16,718
the main parachutes as well as to

5393
04:49:20,470 --> 04:49:18,878
stabilize the vehicle a couple minutes

5394
04:49:22,310 --> 04:49:20,480
about a minute after the drogue

5395
04:49:24,628 --> 04:49:22,320
parachute deployment we will deploy the

5396
04:49:27,030 --> 04:49:24,638
four main parachutes

5397
04:49:29,670 --> 04:49:27,040
if you watched our demo one splashdown

5398
04:49:31,430 --> 04:49:29,680
those are big beautiful orange and white

5399
04:49:35,110 --> 04:49:31,440
parachutes and those further decelerate

5400
04:49:36,868 --> 04:49:35,120
the vehicle down to a mere 15 or 16

5401
04:49:38,948 --> 04:49:36,878
miles per hour that's the speed that

5402
04:49:42,070 --> 04:49:38,958
they'll be going when they splash down

5403
04:49:44,550 --> 04:49:42,080
in the gulf of mexico again we're

5404
04:49:46,948 --> 04:49:44,560
targeting just off the east coast of

5405
04:49:48,948 --> 04:49:46,958
florida near pensacola

5406
04:49:50,868 --> 04:49:48,958
one splashdown is confirmed and we cut

5407
04:49:52,628 --> 04:49:50,878
the main parachutes

5408
04:49:54,788 --> 04:49:52,638
away so they don't

5409
04:49:56,868 --> 04:49:54,798
so they don't pull the capsule recovery

5410
04:49:58,070 --> 04:49:56,878
operations begin immediately so that

5411
04:50:00,470 --> 04:49:58,080
entails

5412
04:50:03,750 --> 04:50:00,480
essentially going getting the

5413
04:50:05,590 --> 04:50:03,760
the vessel excuse me getting the capsule

5414
04:50:07,110 --> 04:50:05,600
out of the water and lifting it onto the

5415
04:50:09,350 --> 04:50:07,120
recovery vessel

5416
04:50:11,990 --> 04:50:09,360
and once that is all secure we open the

5417
04:50:13,430 --> 04:50:12,000
hatch and we get our first glimpse of

5418
04:50:15,110 --> 04:50:13,440
bob and doug

5419
04:50:17,590 --> 04:50:15,120
back here on planet earth for the first

5420
04:50:20,070 --> 04:50:17,600
time since they launched on falcon 9

5421
04:50:22,150 --> 04:50:20,080
back in late may so that particular

5422
04:50:24,070 --> 04:50:22,160
moment will be the first time there they

5423
04:50:25,990 --> 04:50:24,080
get to breathe fresh air

5424
04:50:27,670 --> 04:50:26,000
and we're looking forward to getting

5425
04:50:29,590 --> 04:50:27,680
some thumbs up from them whenever we see

5426
04:50:31,990 --> 04:50:29,600
them exit the capsule

5427
04:50:34,788 --> 04:50:32,000
and everything's lining up for an on

5428
04:50:36,868 --> 04:50:34,798
time splashdown and recovery we've been

5429
04:50:39,110 --> 04:50:36,878
following the progress of go navigator

5430
04:50:39,990 --> 04:50:39,120
as it makes its way out to the recovery

5431
04:50:42,310 --> 04:50:40,000
zone

5432
04:50:44,390 --> 04:50:42,320
it left its port in pensacola just a few

5433
04:50:47,270 --> 04:50:44,400
hours ago and we're tracking that it

5434
04:50:49,830 --> 04:50:47,280
should be arriving on station just about

5435
04:50:51,750 --> 04:50:49,840
at the top of this current hour so it'll

5436
04:50:54,150 --> 04:50:51,760
be there in advance of all of the

5437
04:50:55,590 --> 04:50:54,160
upcoming hardware milestones where we

5438
04:50:57,590 --> 04:50:55,600
get into trunks up and everything like

5439
04:50:59,990 --> 04:50:57,600
that so it'll be there and ready with

5440
04:51:02,628 --> 04:51:00,000
the operational teams a little over 40

5441
04:51:04,390 --> 04:51:02,638
personnel on board from spacex and nasa

5442
04:51:06,390 --> 04:51:04,400
ready to assist in the recovery of the

5443
04:51:08,868 --> 04:51:06,400
capsule and getting bob and doug home

5444
04:51:11,110 --> 04:51:08,878
yeah so as those mission controllers

5445
04:51:13,750 --> 04:51:11,120
there in our mission control center here

5446
04:51:16,070 --> 04:51:13,760
just to my left continue to monitor

5447
04:51:17,110 --> 04:51:16,080
dragon's health we continue to monitor

5448
04:51:18,948 --> 04:51:17,120
twitter

5449
04:51:21,830 --> 04:51:18,958
for your questions we're using the

5450
04:51:23,590 --> 04:51:21,840
hashtag asknasa and we're trying to get

5451
04:51:25,830 --> 04:51:23,600
through to as many questions as possible

5452
04:51:27,830 --> 04:51:25,840
this morning our next question comes to

5453
04:51:29,990 --> 04:51:27,840
us from jackie

5454
04:51:32,070 --> 04:51:30,000
the question is what is the name of the

5455
04:51:34,470 --> 04:51:32,080
dragon recovery vessel that's sailing to

5456
04:51:36,708 --> 04:51:34,480
the splashdown location great question

5457
04:51:38,788 --> 04:51:36,718
especially because we actually have two

5458
04:51:42,470 --> 04:51:38,798
the one that we are utilizing today is

5459
04:51:45,030 --> 04:51:42,480
go navigator this recovery ship is for

5460
04:51:47,510 --> 04:51:45,040
all of our west coast of sydney of all

5461
04:51:50,390 --> 04:51:47,520
of the splashdown locations on the west

5462
04:51:51,510 --> 04:51:50,400
coast of florida so any potential splash

5463
04:51:54,830 --> 04:51:51,520
on location

5464
04:51:57,750 --> 04:51:54,840
in the gulf of mexico is serviced by go

5465
04:51:59,590 --> 04:51:57,760
navigator for our east coast landing

5466
04:52:02,150 --> 04:51:59,600
sites which we are we will not be

5467
04:52:03,990 --> 04:52:02,160
attempting today we use ghost searcher

5468
04:52:06,788 --> 04:52:04,000
both the go navigator and the go

5469
04:52:08,868 --> 04:52:06,798
searcher are identical they have full

5470
04:52:11,590 --> 04:52:08,878
excuse me they have a fully functional

5471
04:52:13,990 --> 04:52:11,600
uh recovery platform as well as medical

5472
04:52:15,830 --> 04:52:14,000
bays so it's really nice that we're able

5473
04:52:18,070 --> 04:52:15,840
to assist

5474
04:52:19,830 --> 04:52:18,080
the departure process so departing the

5475
04:52:21,190 --> 04:52:19,840
international space station it's really

5476
04:52:23,830 --> 04:52:21,200
great that we're able to assist that

5477
04:52:25,830 --> 04:52:23,840
departure process by allowing for more

5478
04:52:28,868 --> 04:52:25,840
opportunities for departure by having

5479
04:52:31,750 --> 04:52:28,878
more landing sites so today we are using

5480
04:52:34,230 --> 04:52:31,760
go navigator and it departed for the

5481
04:52:36,230 --> 04:52:34,240
landing zone about two and a half hours

5482
04:52:38,390 --> 04:52:36,240
ago i think at this point

5483
04:52:40,230 --> 04:52:38,400
and it is enroute to the designated

5484
04:52:42,708 --> 04:52:40,240
landing zone uh just off the coast of

5485
04:52:44,470 --> 04:52:42,718
pensacola all right our next question

5486
04:52:46,230 --> 04:52:44,480
comes from takur who wanted to know

5487
04:52:48,390 --> 04:52:46,240
what's the importance of inventory check

5488
04:52:50,310 --> 04:52:48,400
during the splashdown if you were just

5489
04:52:53,110 --> 04:52:50,320
listening a few minutes ago you heard

5490
04:52:54,948 --> 04:52:53,120
bob doug going through a wide range of

5491
04:52:56,708 --> 04:52:54,958
inventory checks and a lot of it was

5492
04:52:58,230 --> 04:52:56,718
their food and water particularly the

5493
04:52:59,670 --> 04:52:58,240
water as they had just completed that

5494
04:53:01,510 --> 04:52:59,680
fluid loading

5495
04:53:03,590 --> 04:53:01,520
as we've talked about a few times today

5496
04:53:06,550 --> 04:53:03,600
we have to meticulously track every

5497
04:53:08,070 --> 04:53:06,560
single item in for on a spacecraft

5498
04:53:09,750 --> 04:53:08,080
for the obvious reasons like if an

5499
04:53:11,190 --> 04:53:09,760
astronaut needs to find it it helps to

5500
04:53:12,470 --> 04:53:11,200
know where it is

5501
04:53:15,030 --> 04:53:12,480
but and then for some of the less

5502
04:53:16,470 --> 04:53:15,040
obvious reasons like we have to track

5503
04:53:17,990 --> 04:53:16,480
where everything is and if something is

5504
04:53:19,990 --> 04:53:18,000
missing in the spacecraft you have to

5505
04:53:21,910 --> 04:53:20,000
kind of halt work once it's back on the

5506
04:53:24,150 --> 04:53:21,920
ground and make sure you find it and

5507
04:53:26,628 --> 04:53:24,160
then also for things like food and water

5508
04:53:28,868 --> 04:53:26,638
that's something we call a consumable so

5509
04:53:31,270 --> 04:53:28,878
those are essentially resources that you

5510
04:53:33,430 --> 04:53:31,280
have a finite amount of food water

5511
04:53:35,190 --> 04:53:33,440
obviously one of those they have about

5512
04:53:36,868 --> 04:53:35,200
three days worth of food and plenty of

5513
04:53:39,190 --> 04:53:36,878
water on board

5514
04:53:42,628 --> 04:53:39,200
it wasn't the limiting consumable for

5515
04:53:44,230 --> 04:53:42,638
this flight home as was discussed in our

5516
04:53:46,628 --> 04:53:44,240
pre-return

5517
04:53:48,708 --> 04:53:46,638
news conference carbon dioxide scrubbing

5518
04:53:51,030 --> 04:53:48,718
was kind of the low man on the totem

5519
04:53:53,750 --> 04:53:51,040
pole for the trip home they have just

5520
04:53:54,708 --> 04:53:53,760
about three days worth so you have to

5521
04:53:57,350 --> 04:53:54,718
think of

5522
04:53:59,270 --> 04:53:57,360
all these different items that are life

5523
04:54:01,110 --> 04:53:59,280
support systems typically that fall into

5524
04:54:02,788 --> 04:54:01,120
that consumable port

5525
04:54:05,350 --> 04:54:02,798
whenever you're kind of mapping just how

5526
04:54:07,350 --> 04:54:05,360
much on orbit lifetime that you have so

5527
04:54:10,070 --> 04:54:07,360
we knew that we were going to either

5528
04:54:12,390 --> 04:54:10,080
return today or within 47 hours after

5529
04:54:14,868 --> 04:54:12,400
that and so we make sure we have plenty

5530
04:54:17,030 --> 04:54:14,878
for that situation and then hours beyond

5531
04:54:19,430 --> 04:54:17,040
that as just extra margin as we're

5532
04:54:21,190 --> 04:54:19,440
always about redundancy and backup plans

5533
04:54:23,110 --> 04:54:21,200
and everything like that something else

5534
04:54:25,350 --> 04:54:23,120
to consider with respect to the

5535
04:54:27,910 --> 04:54:25,360
importance of inventory during the

5536
04:54:31,430 --> 04:54:27,920
reentry period we don't want anything

5537
04:54:33,510 --> 04:54:31,440
loose flying around that is certainly

5538
04:54:36,150 --> 04:54:33,520
hazardous to the crew and so taking

5539
04:54:38,628 --> 04:54:36,160
inventory of what has been unstowed and

5540
04:54:41,030 --> 04:54:38,638
then restowed allows us to be absolutely

5541
04:54:42,550 --> 04:54:41,040
sure that something didn't accidentally

5542
04:54:44,708 --> 04:54:42,560
because you know as you're floating

5543
04:54:47,270 --> 04:54:44,718
there it is easy to let go of something

5544
04:54:49,510 --> 04:54:47,280
and then it might drift off to behind

5545
04:54:50,948 --> 04:54:49,520
the control panel like dan said before

5546
04:54:52,230 --> 04:54:50,958
it's very easy for things to kind of

5547
04:54:53,830 --> 04:54:52,240
drift off on the international space

5548
04:54:55,670 --> 04:54:53,840
station and get lost

5549
04:54:57,590 --> 04:54:55,680
so really having this inventory allows

5550
04:55:00,470 --> 04:54:57,600
us to make sure that there aren't any

5551
04:55:02,628 --> 04:55:00,480
foreign objects that aren't supposed to

5552
04:55:04,390 --> 04:55:02,638
be out during the times in which they

5553
04:55:06,470 --> 04:55:04,400
are meant to be stoked so

5554
04:55:08,868 --> 04:55:06,480
inventory is important for a number of

5555
04:55:11,430 --> 04:55:08,878
reasons our next question comes to us

5556
04:55:13,830 --> 04:55:11,440
from tim he says my ten-year-old

5557
04:55:15,670 --> 04:55:13,840
daughter haley wants to know how hot the

5558
04:55:18,150 --> 04:55:15,680
exterior of the spacecraft will get

5559
04:55:20,070 --> 04:55:18,160
during re-entry awesome well good

5560
04:55:21,430 --> 04:55:20,080
morning haley or afternoon or evening

5561
04:55:23,670 --> 04:55:21,440
depending on where you are thank you so

5562
04:55:25,670 --> 04:55:23,680
much for tuning in to our webcast we're

5563
04:55:26,788 --> 04:55:25,680
really pleased to have young viewers

5564
04:55:29,430 --> 04:55:26,798
joining us

5565
04:55:32,070 --> 04:55:29,440
for these this historic mission

5566
04:55:34,030 --> 04:55:32,080
so a really good question the outside of

5567
04:55:37,990 --> 04:55:34,040
dragon capsule will reach

5568
04:55:40,150 --> 04:55:38,000
3500 degrees fahrenheit that is very hot

5569
04:55:42,868 --> 04:55:40,160
but bob and doug will be safe and

5570
04:55:45,910 --> 04:55:42,878
comfortable inside of the dragon capsule

5571
04:55:47,910 --> 04:55:45,920
we have measures in place to make sure

5572
04:55:50,708 --> 04:55:47,920
that the inside of the capsule will be

5573
04:55:53,430 --> 04:55:50,718
flushed with cold air as well as the air

5574
04:55:54,788 --> 04:55:53,440
inside of their spacesuits so even

5575
04:55:57,110 --> 04:55:54,798
though the outside will be getting

5576
04:55:58,948 --> 04:55:57,120
really hot bob and doug will barely be

5577
04:56:00,470 --> 04:55:58,958
breaking a sweat

5578
04:56:02,230 --> 04:56:00,480
all right our next question comes from

5579
04:56:04,550 --> 04:56:02,240
mohan who wants to know will the super

5580
04:56:07,030 --> 04:56:04,560
draco thrusters be a backup to the

5581
04:56:09,110 --> 04:56:07,040
parachutes it's a good question because

5582
04:56:11,190 --> 04:56:09,120
one of the earliest designs of dragon

5583
04:56:13,110 --> 04:56:11,200
had it doing what's called a propulsive

5584
04:56:14,230 --> 04:56:13,120
landing so kind of like how the falcon 9

5585
04:56:16,788 --> 04:56:14,240
comes back

5586
04:56:18,708 --> 04:56:16,798
an early design of this crew dragon had

5587
04:56:20,550 --> 04:56:18,718
it landing propulsively so using those

5588
04:56:21,750 --> 04:56:20,560
super dracos to touch down on like a

5589
04:56:23,510 --> 04:56:21,760
runway

5590
04:56:24,948 --> 04:56:23,520
that's no longer in dragon's

5591
04:56:26,550 --> 04:56:24,958
configuration

5592
04:56:28,708 --> 04:56:26,560
in fact those

5593
04:56:31,030 --> 04:56:28,718
super draco thrusters are

5594
04:56:33,190 --> 04:56:31,040
completely inhibited following a

5595
04:56:35,990 --> 04:56:33,200
successful flight into orbit they're

5596
04:56:38,708 --> 04:56:36,000
only used for an emergency escape

5597
04:56:40,628 --> 04:56:38,718
situation either on the pad or during

5598
04:56:43,670 --> 04:56:40,638
the initial climb up to orbit they

5599
04:56:46,070 --> 04:56:43,680
enable dragon to do that escape from the

5600
04:56:48,390 --> 04:56:46,080
pad all the way up so you have kind of

5601
04:56:50,470 --> 04:56:48,400
that extra safety net your entire way

5602
04:56:51,830 --> 04:56:50,480
uphill but once they're on orbit and

5603
04:56:53,750 --> 04:56:51,840
they're making their way to the space

5604
04:56:55,910 --> 04:56:53,760
station or even when we're coming home

5605
04:56:58,470 --> 04:56:55,920
those thrusters are disabled we're only

5606
04:57:00,310 --> 04:56:58,480
using the smaller draco thrusters around

5607
04:57:01,670 --> 04:57:00,320
the service section so the bottom of the

5608
04:57:03,510 --> 04:57:01,680
capsule itself

5609
04:57:06,230 --> 04:57:03,520
and the four at the very top the forward

5610
04:57:08,708 --> 04:57:06,240
bulkhead thrusters

5611
04:57:09,990 --> 04:57:08,718
um our next question from amy wants to

5612
04:57:12,390 --> 04:57:10,000
know what happens to the parachutes

5613
04:57:14,550 --> 04:57:12,400
after splashdown are they recovered yeah

5614
04:57:16,948 --> 04:57:14,560
absolutely so there will be after

5615
04:57:18,788 --> 04:57:16,958
splashdown there will be two fast boats

5616
04:57:21,190 --> 04:57:18,798
or smaller boats that will be

5617
04:57:23,750 --> 04:57:21,200
approaching the dragon capsule the first

5618
04:57:25,190 --> 04:57:23,760
boat is responsible to for determining

5619
04:57:27,750 --> 04:57:25,200
that there aren't any

5620
04:57:30,868 --> 04:57:27,760
toxic vapors surrounding the capsule

5621
04:57:33,110 --> 04:57:30,878
that that boat that fast boat will then

5622
04:57:35,590 --> 04:57:33,120
also be responsible for preparing the

5623
04:57:37,270 --> 04:57:35,600
capsule for lift out of the water the

5624
04:57:39,030 --> 04:57:37,280
second boat is responsible for

5625
04:57:39,910 --> 04:57:39,040
retrieving the parachutes out of the

5626
04:57:41,270 --> 04:57:39,920
water

5627
04:57:43,270 --> 04:57:41,280
we definitely don't want to leave any

5628
04:57:45,510 --> 04:57:43,280
waste behind where possible

5629
04:57:47,910 --> 04:57:45,520
and so that second boat is responsible

5630
04:57:50,150 --> 04:57:47,920
for going and retrieving the parachutes

5631
04:57:53,430 --> 04:57:50,160
after splashdown those parachutes are

5632
04:57:55,430 --> 04:57:53,440
automatically uh cut so that there isn't

5633
04:57:57,190 --> 04:57:55,440
there's no potential that if there was a

5634
04:57:59,270 --> 04:57:57,200
little bit of wind that the dragon

5635
04:58:00,788 --> 04:57:59,280
capsule wouldn't be moved due to wind

5636
04:58:02,948 --> 04:58:00,798
catching in those parachutes so great

5637
04:58:04,310 --> 04:58:02,958
question but short answer is yeah

5638
04:58:05,590 --> 04:58:04,320
they're cut

5639
04:58:07,910 --> 04:58:05,600
they're automatically cut after

5640
04:58:09,590 --> 04:58:07,920
splashdown and then one of the crews

5641
04:58:11,030 --> 04:58:09,600
from the fast boats is responsible for

5642
04:58:13,110 --> 04:58:11,040
going to pick them up

5643
04:58:15,830 --> 04:58:13,120
the next question we have coming from

5644
04:58:18,550 --> 04:58:15,840
hashtag ask nasa on twitter comes to us

5645
04:58:21,030 --> 04:58:18,560
from novicon what will be the purpose of

5646
04:58:22,948 --> 04:58:21,040
the crew for the crew one mission

5647
04:58:25,350 --> 04:58:22,958
the crew one mission will be what we

5648
04:58:27,350 --> 04:58:25,360
call the first operational flight of the

5649
04:58:29,190 --> 04:58:27,360
dragon spacecraft so the mission we're

5650
04:58:31,190 --> 04:58:29,200
still on right now is a demonstration

5651
04:58:32,868 --> 04:58:31,200
this is still a test mission this is

5652
04:58:34,550 --> 04:58:32,878
when we're really proving out dragon's

5653
04:58:36,070 --> 04:58:34,560
capabilities from launch all the way

5654
04:58:38,310 --> 04:58:36,080
through splashdown

5655
04:58:39,430 --> 04:58:38,320
after this test if everything goes well

5656
04:58:41,590 --> 04:58:39,440
and we're

5657
04:58:42,948 --> 04:58:41,600
lined up great for a splashdown today

5658
04:58:45,350 --> 04:58:42,958
we'll sit down and we'll go through a

5659
04:58:47,190 --> 04:58:45,360
certification process for spacex to fly

5660
04:58:49,990 --> 04:58:47,200
operational missions this means they'll

5661
04:58:52,390 --> 04:58:50,000
be flying regular expedition

5662
04:58:54,550 --> 04:58:52,400
long duration flights so the crew one

5663
04:58:56,868 --> 04:58:54,560
will be the first four-person crew to

5664
04:58:58,470 --> 04:58:56,878
launch in the dragon spacecraft and then

5665
04:58:59,990 --> 04:58:58,480
spend six months on board the

5666
04:59:01,590 --> 04:59:00,000
international space station so we'll

5667
04:59:03,910 --> 04:59:01,600
have four individuals

5668
04:59:05,830 --> 04:59:03,920
mike hopkins victor glover shannon

5669
04:59:08,550 --> 04:59:05,840
walker and soichi naguchi from the

5670
04:59:10,470 --> 04:59:08,560
japanese aerospace exploration agency

5671
04:59:12,550 --> 04:59:10,480
launching a dragon and then spending six

5672
04:59:14,628 --> 04:59:12,560
months onboard the space station doing

5673
04:59:17,270 --> 04:59:14,638
science experiments uh conducting

5674
04:59:19,590 --> 04:59:17,280
spacewalks repairs everything that a

5675
04:59:22,310 --> 04:59:19,600
normal expedition crew does they'll just

5676
04:59:24,230 --> 04:59:22,320
be arriving and leaving in a dragon yeah

5677
04:59:26,470 --> 04:59:24,240
i think commander chris cassidy will

5678
04:59:28,948 --> 04:59:26,480
still be on board with our targeted

5679
04:59:30,230 --> 04:59:28,958
given the the current targeted crew one

5680
04:59:32,110 --> 04:59:30,240
launcher

5681
04:59:35,430 --> 04:59:32,120
dragon prom check from the plt

5682
04:59:35,440 --> 04:59:44,470
we've got you five by five bob

5683
04:59:48,350 --> 04:59:47,350
spacex and uh

5684
04:59:50,708 --> 04:59:48,360
check between us

5685
04:59:52,708 --> 04:59:50,718
[Music]

5686
04:59:54,230 --> 04:59:52,718
and uh please repeat the last five

5687
05:00:01,910 --> 04:59:54,240
seconds of that call we had a bit of a

5688
05:00:01,920 --> 05:00:13,670
thank you out of clear as well

5689
05:00:17,110 --> 05:00:15,270
and uh

5690
05:00:19,030 --> 05:00:17,120
dragon we copy that you heard us loud

5691
05:00:21,590 --> 05:00:19,040
and clear unfortunately the rest of the

5692
05:00:26,550 --> 05:00:21,600
message was garbled please repeat one

5693
05:00:31,110 --> 05:00:28,230
yeah we've got a good contract between

5694
05:00:33,270 --> 05:00:31,120
both of us and we are complete with suit

5695
05:00:35,270 --> 05:00:33,280
counting four decibel zero one zero how

5696
05:00:40,150 --> 05:00:35,280
copy

5697
05:00:51,670 --> 05:00:40,160
you are complete with suit dotting

5698
05:00:55,990 --> 05:00:54,390
okay it sounds like the crew now suited

5699
05:00:57,750 --> 05:00:56,000
up they just conducted those

5700
05:01:00,470 --> 05:00:57,760
communications checks those comp checks

5701
05:01:01,990 --> 05:01:00,480
with the core here in hawthorne the core

5702
05:01:03,990 --> 05:01:02,000
of the crew operations responsible

5703
05:01:06,390 --> 05:01:04,000
engineer that's essentially the the

5704
05:01:08,390 --> 05:01:06,400
person who's talking directly to bob and

5705
05:01:10,150 --> 05:01:08,400
doug throughout their flight uh that's

5706
05:01:12,628 --> 05:01:10,160
rotated to through a couple of different

5707
05:01:14,310 --> 05:01:12,638
positions as we're on the third shift

5708
05:01:16,390 --> 05:01:14,320
of their flight home

5709
05:01:18,550 --> 05:01:16,400
and that'll be pretty much the person

5710
05:01:19,350 --> 05:01:18,560
who's getting all of the updates to and

5711
05:01:21,190 --> 05:01:19,360
from

5712
05:01:23,030 --> 05:01:21,200
bob and doug being that liaison between

5713
05:01:24,550 --> 05:01:23,040
the teams on the ground

5714
05:01:26,470 --> 05:01:24,560
but they they did those comm checks

5715
05:01:28,390 --> 05:01:26,480
successfully they are in their suits

5716
05:01:30,550 --> 05:01:28,400
they're going to stay in their suits and

5717
05:01:31,990 --> 05:01:30,560
in their seats for the rest of the day

5718
05:01:33,510 --> 05:01:32,000
pretty much from

5719
05:01:35,750 --> 05:01:33,520
that deorbit

5720
05:01:37,910 --> 05:01:35,760
looking for an update on uh sections one

5721
05:01:58,550 --> 05:01:37,920
through four of four decimal seven zero

5722
05:02:04,390 --> 05:02:01,750
and spacex dragon we are complete with

5723
05:02:07,190 --> 05:02:04,400
uh sections one through four

5724
05:02:11,990 --> 05:02:07,200
and uh looking at section five

5725
05:02:14,070 --> 05:02:12,000
uh the only thing left there to do is uh

5726
05:02:14,948 --> 05:02:14,080
alpha decimal two

5727
05:02:16,708 --> 05:02:14,958
uh

5728
05:02:21,110 --> 05:02:16,718
as far as so yeah it's simply check i

5729
05:02:26,628 --> 05:02:23,430
okay copy uh sections one through four

5730
05:02:31,910 --> 05:02:26,638
are complete and uh it sounds like

5731
05:02:35,110 --> 05:02:33,430
sounds like you're completing fluid

5732
05:02:38,708 --> 05:02:35,120
loading and standing by for the leak

5733
05:02:38,718 --> 05:02:41,270
that's

5734
05:02:41,280 --> 05:02:46,550
thanks doug appreciate it

5735
05:02:51,430 --> 05:02:48,708
so what we heard there was communication

5736
05:02:53,430 --> 05:02:51,440
between dragon and and mike i just

5737
05:02:55,350 --> 05:02:53,440
wanted to check back with you on the com

5738
05:02:57,910 --> 05:02:55,360
dropout that you had on

5739
05:03:00,470 --> 05:02:57,920
the last two calls that i made to you

5740
05:03:02,868 --> 05:03:00,480
how is this calm now was it

5741
05:03:07,590 --> 05:03:02,878
explainable as just random dropouts or

5742
05:03:10,788 --> 05:03:08,868
okay uh

5743
05:03:12,150 --> 05:03:10,798
bob we had you five by five just then

5744
05:03:14,310 --> 05:03:12,160
much better than before we're

5745
05:03:16,230 --> 05:03:14,320
investigating root cause but given uh

5746
05:03:18,070 --> 05:03:16,240
the clarity of your call just now i

5747
05:03:23,430 --> 05:03:18,080
would suspect your audio system is

5748
05:03:29,750 --> 05:03:24,410
happy thank you

5749
05:03:33,350 --> 05:03:31,030
okay so there we heard a little bit of

5750
05:03:35,830 --> 05:03:33,360
communication just confirming that we

5751
05:03:37,430 --> 05:03:35,840
were that mission control was able to

5752
05:03:39,350 --> 05:03:37,440
read or hear

5753
05:03:41,910 --> 05:03:39,360
as it's referred to

5754
05:03:45,030 --> 05:03:41,920
bob and doug clearly as they have put on

5755
05:03:47,670 --> 05:03:45,040
their suits we also heard the go for

5756
05:03:49,990 --> 05:03:47,680
leak check so now that the suits are on

5757
05:03:51,750 --> 05:03:50,000
we will be performing a quick leak check

5758
05:03:54,230 --> 05:03:51,760
we do this every time the suits are put

5759
05:03:56,150 --> 05:03:54,240
on or donned as you heard it called

5760
05:03:57,750 --> 05:03:56,160
basically this is where we pressurize

5761
05:03:59,990 --> 05:03:57,760
the suits it's the only time that we

5762
05:04:01,990 --> 05:04:00,000
pressurize them throughout the mission

5763
05:04:03,110 --> 05:04:02,000
and it's essentially to make sure that

5764
05:04:05,430 --> 05:04:03,120
you know all the zippers are in the

5765
05:04:08,390 --> 05:04:05,440
right are zipped up properly all it

5766
05:04:10,390 --> 05:04:08,400
takes is you know one small unzipped

5767
05:04:12,708 --> 05:04:10,400
piece to not hold the pressure so we

5768
05:04:15,590 --> 05:04:12,718
make sure that everything is uh fitted

5769
05:04:17,590 --> 05:04:15,600
up accordingly and that it's ready to go

5770
05:04:20,628 --> 05:04:17,600
in case of the in case of

5771
05:04:22,948 --> 05:04:20,638
a need to pressurize the suits later in

5772
05:04:25,510 --> 05:04:22,958
in the in the mission uh unlikely but

5773
05:04:27,190 --> 05:04:25,520
it's nice to know you know just for that

5774
05:04:28,628 --> 05:04:27,200
for testing purposes to know that that

5775
05:04:30,788 --> 05:04:28,638
capability is there that's what they're

5776
05:04:33,270 --> 05:04:30,798
designed for so that leak check will

5777
05:04:35,990 --> 05:04:33,280
commence and um

5778
05:04:38,390 --> 05:04:36,000
after we get that uh

5779
05:04:39,510 --> 05:04:38,400
we'll pressurize the the the suits

5780
05:04:41,510 --> 05:04:39,520
themselves and then they will

5781
05:04:44,628 --> 05:04:41,520
depressurize bob and doug will be able

5782
05:04:46,628 --> 05:04:44,638
to lift the visor on their helmet again

5783
05:04:48,390 --> 05:04:46,638
and then that's essentially you know

5784
05:04:51,190 --> 05:04:48,400
that's that's what though what they will

5785
05:04:53,190 --> 05:04:51,200
be wearing uh during this last phase of

5786
05:04:54,708 --> 05:04:53,200
their mission as they re-enter the

5787
05:04:58,230 --> 05:04:54,718
earth's atmosphere

5788
05:04:59,670 --> 05:04:58,240
so a lot of good stuff there again

5789
05:05:01,910 --> 05:04:59,680
nope

5790
05:05:03,590 --> 05:05:01,920
no call there

5791
05:05:05,590 --> 05:05:03,600
like we said before we're taking your

5792
05:05:09,110 --> 05:05:05,600
questions through twitter this morning

5793
05:05:11,510 --> 05:05:09,120
using the hashtag ask nasa our next

5794
05:05:14,150 --> 05:05:11,520
question comes to us from robert

5795
05:05:16,230 --> 05:05:14,160
is the u.s navy supporting recovery with

5796
05:05:18,390 --> 05:05:16,240
ships and aircraft

5797
05:05:20,390 --> 05:05:18,400
they are not i suspect that that

5798
05:05:22,788 --> 05:05:20,400
question comes from the last time we did

5799
05:05:24,628 --> 05:05:22,798
splash downs with u.s spacecraft and

5800
05:05:26,390 --> 05:05:24,638
astronauts where we had the navy

5801
05:05:28,230 --> 05:05:26,400
assisting throughout the apollo program

5802
05:05:29,590 --> 05:05:28,240
for the recoveries they are not

5803
05:05:32,070 --> 05:05:29,600
assisting in this

5804
05:05:35,110 --> 05:05:32,080
all of the recovery assets for the

5805
05:05:37,030 --> 05:05:35,120
nominal mission are spacex so spacex

5806
05:05:39,030 --> 05:05:37,040
owns both recovery ships the go

5807
05:05:41,270 --> 05:05:39,040
navigator and the go searcher

5808
05:05:43,030 --> 05:05:41,280
and then contract out with the different

5809
05:05:46,628 --> 05:05:43,040
helicopters and other assets that are

5810
05:05:48,470 --> 05:05:46,638
used in this recovery nasa does have

5811
05:05:50,628 --> 05:05:48,480
a department of defense backup

5812
05:05:52,868 --> 05:05:50,638
essentially if bob and doug were to have

5813
05:05:54,628 --> 05:05:52,878
to splash down anywhere other than those

5814
05:05:56,868 --> 05:05:54,638
seven sites that we target around

5815
05:05:57,990 --> 05:05:56,878
florida we have the capability to call

5816
05:06:01,430 --> 05:05:58,000
them up

5817
05:06:03,510 --> 05:06:01,440
to effect a fast rescue and recovery uh

5818
05:06:05,350 --> 05:06:03,520
using para jumpers or whatever assets

5819
05:06:08,070 --> 05:06:05,360
are available to us

5820
05:06:09,910 --> 05:06:08,080
they are also called up on launch days

5821
05:06:11,750 --> 05:06:09,920
in the event that we were to have an

5822
05:06:13,830 --> 05:06:11,760
abort on the way to orbit with them

5823
05:06:14,868 --> 05:06:13,840
coming down somewhere in the atlantic

5824
05:06:18,070 --> 05:06:14,878
but

5825
05:06:19,830 --> 05:06:18,080
for now today everything is spacex and

5826
05:06:22,390 --> 05:06:19,840
nasa

5827
05:06:23,350 --> 05:06:22,400
another question coming to us from whom

5828
05:06:25,430 --> 05:06:23,360
z

5829
05:06:27,270 --> 05:06:25,440
is there a time limit on how long the

5830
05:06:29,510 --> 05:06:27,280
capsule can be left to flow in the

5831
05:06:30,708 --> 05:06:29,520
atlantic ocean before it needs to be

5832
05:06:32,628 --> 05:06:30,718
recovered

5833
05:06:35,030 --> 05:06:32,638
yeah so obviously we want to get the

5834
05:06:36,550 --> 05:06:35,040
crew out as soon as possible let them

5835
05:06:38,470 --> 05:06:36,560
get out and stretch their legs and begin

5836
05:06:40,708 --> 05:06:38,480
their medical evaluations

5837
05:06:42,550 --> 05:06:40,718
however the capsule would be able to

5838
05:06:45,190 --> 05:06:42,560
float there for a couple of days like we

5839
05:06:46,628 --> 05:06:45,200
mentioned before there is enough onboard

5840
05:06:48,470 --> 05:06:46,638
water and food

5841
05:06:50,550 --> 05:06:48,480
they would be comfortable

5842
05:06:53,030 --> 05:06:50,560
although if the waves pick up i

5843
05:06:55,910 --> 05:06:53,040
certainly would not be comfortable

5844
05:06:58,230 --> 05:06:55,920
that being said uh we do strive to

5845
05:07:01,190 --> 05:06:58,240
recover them as soon as possible uh this

5846
05:07:03,270 --> 05:07:01,200
is part of the reason why we have uh

5847
05:07:05,350 --> 05:07:03,280
numerous potential landing zone sites

5848
05:07:07,590 --> 05:07:05,360
and we have special criteria for where

5849
05:07:09,990 --> 05:07:07,600
they actually land to ensure that we're

5850
05:07:12,070 --> 05:07:10,000
able to get the crew

5851
05:07:15,430 --> 05:07:12,080
up and out of the water and into the

5852
05:07:17,430 --> 05:07:15,440
medical bays essentially within an hour

5853
05:07:19,350 --> 05:07:17,440
after splashdown

5854
05:07:21,190 --> 05:07:19,360
all right our next one comes from mark

5855
05:07:23,110 --> 05:07:21,200
who wants to know can they take over

5856
05:07:25,590 --> 05:07:23,120
from the computer and do a manual

5857
05:07:27,110 --> 05:07:25,600
splashdown if required

5858
05:07:29,430 --> 05:07:27,120
they can

5859
05:07:31,590 --> 05:07:29,440
initiating a deorbit or an emergency

5860
05:07:34,310 --> 05:07:31,600
de-orbit is one of the capabilities

5861
05:07:35,990 --> 05:07:34,320
available to crew members on board you

5862
05:07:38,868 --> 05:07:36,000
would have to be in a pretty extreme

5863
05:07:40,470 --> 05:07:38,878
situation to do that

5864
05:07:41,830 --> 05:07:40,480
something we're obviously not in today

5865
05:07:43,910 --> 05:07:41,840
is everything's going really smoothly

5866
05:07:46,310 --> 05:07:43,920
with dragon but that is something that's

5867
05:07:48,550 --> 05:07:46,320
available to them they also have the

5868
05:07:50,310 --> 05:07:48,560
capability to manually step in for a

5869
05:07:51,430 --> 05:07:50,320
number of the different steps during the

5870
05:07:54,628 --> 05:07:51,440
re-entry

5871
05:07:56,470 --> 05:07:54,638
but mainly for any parachute deployments

5872
05:07:57,910 --> 05:07:56,480
or even cutting the parachutes after

5873
05:07:59,670 --> 05:07:57,920
they've splashed down

5874
05:08:01,750 --> 05:07:59,680
that doesn't happen automatically they

5875
05:08:03,270 --> 05:08:01,760
have a button right in front of them on

5876
05:08:05,190 --> 05:08:03,280
their displays where they can make that

5877
05:08:07,670 --> 05:08:05,200
happen so they do have quite a bit of

5878
05:08:10,230 --> 05:08:07,680
capability to jump in if required yeah

5879
05:08:12,628 --> 05:08:10,240
that is one of the few hardwired

5880
05:08:14,868 --> 05:08:12,638
buttons on their display panel but it is

5881
05:08:16,628 --> 05:08:14,878
certainly not one that can be triggered

5882
05:08:18,230 --> 05:08:16,638
accidentally it is a two-step

5883
05:08:20,150 --> 05:08:18,240
verification

5884
05:08:22,788 --> 05:08:20,160
lever essentially so

5885
05:08:24,230 --> 05:08:22,798
no need to worry about performing an

5886
05:08:27,590 --> 05:08:24,240
emergency door

5887
05:08:30,550 --> 05:08:27,600
emergency deorbit accidentally

5888
05:08:32,310 --> 05:08:30,560
next question comes to us from nasa plus

5889
05:08:34,230 --> 05:08:32,320
space equals heart

5890
05:08:36,868 --> 05:08:34,240
i couldn't agree more

5891
05:08:39,670 --> 05:08:36,878
will this crew dragon be reused yes it

5892
05:08:43,350 --> 05:08:39,680
will this particular capsule is intended

5893
05:08:46,070 --> 05:08:43,360
to be reused on the crew 2 mission which

5894
05:08:48,310 --> 05:08:46,080
will be launching sometime next year

5895
05:08:49,990 --> 05:08:48,320
and yeah we already have plans for reuse

5896
05:08:52,948 --> 05:08:50,000
for it in fact the

5897
05:08:56,390 --> 05:08:52,958
team at the cape is already preparing to

5898
05:08:58,070 --> 05:08:56,400
begin those refurbishment processes as

5899
05:08:59,910 --> 05:08:58,080
soon as the capsule lands essentially

5900
05:09:02,948 --> 05:08:59,920
really getting a head start on that the

5901
05:09:04,788 --> 05:09:02,958
capsule is waterproof that was a process

5902
05:09:06,868 --> 05:09:04,798
that we learned how to do through the

5903
05:09:09,830 --> 05:09:06,878
crew cargo program

5904
05:09:11,750 --> 05:09:09,840
our reuse efforts with that program

5905
05:09:12,788 --> 05:09:11,760
with our previous version of the dragon

5906
05:09:15,270 --> 05:09:12,798
capsule

5907
05:09:17,350 --> 05:09:15,280
also known as dragon one uh the process

5908
05:09:19,270 --> 05:09:17,360
of making that waterproof

5909
05:09:21,670 --> 05:09:19,280
has trent that knowledge that we learned

5910
05:09:23,910 --> 05:09:21,680
from that has transferred over to crude

5911
05:09:26,868 --> 05:09:23,920
dragon capsules and it's safe to say

5912
05:09:29,350 --> 05:09:26,878
that it is with very little

5913
05:09:30,550 --> 05:09:29,360
refurbishment required to the internal

5914
05:09:31,910 --> 05:09:30,560
hardware

5915
05:09:33,110 --> 05:09:31,920
you know the

5916
05:09:35,110 --> 05:09:33,120
there's very little refurbishment

5917
05:09:37,590 --> 05:09:35,120
required because we're able to keep it

5918
05:09:39,670 --> 05:09:37,600
watertight and eliminate any exposure to

5919
05:09:41,830 --> 05:09:39,680
salt water which for metallic surfaces

5920
05:09:44,310 --> 05:09:41,840
does cause corrosion which is no good

5921
05:09:46,310 --> 05:09:44,320
for space flight so uh short answer is

5922
05:09:49,350 --> 05:09:46,320
that yeah we will be reusing this as

5923
05:09:50,628 --> 05:09:49,360
soon as next year on the nasa crew 2

5924
05:09:52,550 --> 05:09:50,638
mission

5925
05:09:55,430 --> 05:09:52,560
all right our next one from lisa what

5926
05:09:57,590 --> 05:09:55,440
are bob and doug bringing back from iss

5927
05:09:59,510 --> 05:09:57,600
if anything

5928
05:10:02,470 --> 05:09:59,520
there's quite a bit actually

5929
05:10:05,590 --> 05:10:02,480
they have about 150 kilograms or a

5930
05:10:07,350 --> 05:10:05,600
little over 330 pounds of cargo

5931
05:10:09,670 --> 05:10:07,360
essentially strapped to the ground right

5932
05:10:11,750 --> 05:10:09,680
underneath their seats the lion's share

5933
05:10:14,310 --> 05:10:11,760
of that is utilization or science

5934
05:10:16,628 --> 05:10:14,320
samples a lot of it cold stowage samples

5935
05:10:18,948 --> 05:10:16,638
that's kept in powered freezers those

5936
05:10:21,990 --> 05:10:18,958
samples coming from a range of

5937
05:10:23,750 --> 05:10:22,000
biological biomedical studies a lot of

5938
05:10:25,990 --> 05:10:23,760
them with the astronauts themselves as

5939
05:10:27,670 --> 05:10:26,000
this as the test subjects

5940
05:10:30,470 --> 05:10:27,680
as cargo return a pretty critical

5941
05:10:32,150 --> 05:10:30,480
capability as we do we execute a lot of

5942
05:10:34,150 --> 05:10:32,160
the science on station but we need to

5943
05:10:36,788 --> 05:10:34,160
return a lot of the samples for analysis

5944
05:10:38,708 --> 05:10:36,798
down in labs here on earth and they're

5945
05:10:40,788 --> 05:10:38,718
going to be bringing a lot of that down

5946
05:10:42,868 --> 05:10:40,798
they're also returning some vehicle

5947
05:10:44,550 --> 05:10:42,878
hardware items that have either

5948
05:10:46,310 --> 05:10:44,560
malfunctioned or just passed their

5949
05:10:47,830 --> 05:10:46,320
service life and need to come home or

5950
05:10:49,590 --> 05:10:47,840
get inspected

5951
05:10:51,190 --> 05:10:49,600
and then a couple of their personal

5952
05:10:53,270 --> 05:10:51,200
items things like their sleeping bags

5953
05:10:54,708 --> 05:10:53,280
are coming back with them and they also

5954
05:10:56,788 --> 05:10:54,718
have a couple of special items we've

5955
05:10:59,270 --> 05:10:56,798
touched on a few times including that

5956
05:11:01,350 --> 05:10:59,280
tremor dinosaur that was chosen by both

5957
05:11:02,708 --> 05:11:01,360
of their sons as their zero g indicator

5958
05:11:04,550 --> 05:11:02,718
for this mission

5959
05:11:06,670 --> 05:11:04,560
and the flag that was left there by doug

5960
05:11:09,590 --> 05:11:06,680
hurley and his fellow crewmates of

5961
05:11:11,510 --> 05:11:09,600
sts-135 the final space shuttle mission

5962
05:11:14,310 --> 05:11:11,520
that is coming home it's been up there

5963
05:11:17,110 --> 05:11:14,320
for just about nine years and it will

5964
05:11:19,830 --> 05:11:17,120
fly again when we send humans around the

5965
05:11:21,990 --> 05:11:19,840
moon in the not too distant future and i

5966
05:11:24,150 --> 05:11:22,000
know we haven't seen it

5967
05:11:26,310 --> 05:11:24,160
but i have heard that little earth is

5968
05:11:28,150 --> 05:11:26,320
also coming back i almost forgot about

5969
05:11:30,230 --> 05:11:28,160
that

5970
05:11:32,470 --> 05:11:30,240
little earth was the zero g indicator on

5971
05:11:34,390 --> 05:11:32,480
demo one and remained on station after

5972
05:11:36,550 --> 05:11:34,400
that mission and it's

5973
05:11:39,670 --> 05:11:36,560
pretty sure it was packed away to come

5974
05:11:42,150 --> 05:11:39,680
home on demo too i think you're right

5975
05:11:45,510 --> 05:11:42,160
so right now dragon is currently flying

5976
05:11:47,990 --> 05:11:45,520
over the far south pacific ocean

5977
05:11:50,470 --> 05:11:48,000
we have a nice little map here to show

5978
05:11:52,310 --> 05:11:50,480
you of our ground tracking so there you

5979
05:11:54,310 --> 05:11:52,320
can see it on your screen

5980
05:11:57,670 --> 05:11:54,320
if you're curious the yellow indicates

5981
05:11:59,590 --> 05:11:57,680
where the capsule is in daylight the red

5982
05:12:01,670 --> 05:11:59,600
part of the line indicates where it goes

5983
05:12:04,310 --> 05:12:01,680
into eclipse or

5984
05:12:06,788 --> 05:12:04,320
whenever it's basically hiding in

5985
05:12:08,550 --> 05:12:06,798
earth's shadow so right now it's in

5986
05:12:11,030 --> 05:12:08,560
daylight bob and doug must be getting

5987
05:12:14,310 --> 05:12:11,040
some pretty spectacular views as they're

5988
05:12:16,550 --> 05:12:14,320
completing their suit up process but at

5989
05:12:18,948 --> 05:12:16,560
this point we're going to take a quick

5990
05:13:23,110 --> 05:12:18,958
break and leave you with our lovely

5991
05:13:23,120 --> 05:13:28,550
dragon spacex for video

5992
05:13:31,510 --> 05:13:29,910
go ahead

5993
05:13:36,550 --> 05:13:31,520
yeah request to come back aboard when

5994
05:13:40,390 --> 05:13:37,670
we are

5995
05:16:42,550 --> 05:13:40,400
ready for you to come aboard

5996
05:16:47,110 --> 05:16:45,030
dragon spacex you are go for procedure

5997
05:16:51,670 --> 05:16:47,120
four decimal zero one one suit leak

5998
05:16:51,680 --> 05:17:05,590
the check

5999
05:17:10,390 --> 05:17:07,510
okay so we just heard the crew now

6000
05:17:12,150 --> 05:17:10,400
stepping into suit leak checks

6001
05:17:12,868 --> 05:17:12,160
as we've described a few times this is

6002
05:17:14,390 --> 05:17:12,878
when they're actually going to

6003
05:17:16,390 --> 05:17:14,400
pressurize

6004
05:17:18,708 --> 05:17:16,400
their suits that they wear for launch

6005
05:17:20,948 --> 05:17:18,718
and entry really any of the dynamic

6006
05:17:23,030 --> 05:17:20,958
phases of the mission so they'll

6007
05:17:26,708 --> 05:17:23,040
completely zip up and seal the suits and

6008
05:17:26,718 --> 05:17:30,550
we are ready to pressurize

6009
05:17:30,560 --> 05:17:37,430
dragon spacex you are go to pressurize

6010
05:17:40,628 --> 05:17:39,190
so bob bank and doug hurley getting to

6011
05:17:41,670 --> 05:17:40,638
go they're going to pressurize their

6012
05:17:43,830 --> 05:17:41,680
suits

6013
05:17:47,190 --> 05:17:43,840
so pressurized nitrox now going to flow

6014
05:17:48,788 --> 05:17:47,200
in again these suits are

6015
05:17:51,110 --> 05:17:48,798
we have confirmation the leak check is

6016
05:17:52,708 --> 05:17:51,120
in progress so these suits are worn as

6017
05:17:54,550 --> 05:17:52,718
just another line of defense to help

6018
05:17:55,590 --> 05:17:54,560
protect the crew members

6019
05:17:57,110 --> 05:17:55,600
from the

6020
05:17:59,830 --> 05:17:57,120
really the harsh environment of the

6021
05:18:01,750 --> 05:17:59,840
outer space if they were to experience a

6022
05:18:03,510 --> 05:18:01,760
cabin depressurization

6023
05:18:04,868 --> 05:18:03,520
any kind of poisonous leak in their

6024
05:18:06,550 --> 05:18:04,878
atmosphere

6025
05:18:08,150 --> 05:18:06,560
or even a fire these suits are designed

6026
05:18:09,430 --> 05:18:08,160
to protect from all of those different

6027
05:18:11,590 --> 05:18:09,440
instances

6028
05:18:14,070 --> 05:18:11,600
so the suit leak check is pretty

6029
05:18:16,310 --> 05:18:14,080
standard anytime before we get into one

6030
05:18:18,070 --> 05:18:16,320
of these dynamic operations we just want

6031
05:18:19,430 --> 05:18:18,080
one more check to make sure that the

6032
05:18:21,990 --> 05:18:19,440
suit is

6033
05:18:23,990 --> 05:18:22,000
ready to go in case it's called upon

6034
05:18:25,510 --> 05:18:24,000
and so they'll pressurize now and flow

6035
05:18:27,510 --> 05:18:25,520
some nitrox some

6036
05:18:29,910 --> 05:18:27,520
nitrogen and oxygen

6037
05:18:32,550 --> 05:18:29,920
through their suits they'll look for it

6038
05:18:33,750 --> 05:18:32,560
to maintain a constant pressure

6039
05:18:35,670 --> 05:18:33,760
and then once that's done they'll

6040
05:18:36,550 --> 05:18:35,680
depressurize the suits

6041
05:18:39,120 --> 05:18:36,560
and

6042
05:18:42,550 --> 05:18:39,130
they'll leave the zipper open

6043
05:18:46,070 --> 05:18:44,390
they'll typically leave one zipper just

6044
05:18:48,788 --> 05:18:46,080
unzipped a little bit when they're not

6045
05:18:50,230 --> 05:18:48,798
pressurized they'll still have cool air

6046
05:18:52,070 --> 05:18:50,240
flowing through in fact they'll do

6047
05:18:54,470 --> 05:18:52,080
what's called a soup purge

6048
05:18:56,230 --> 05:18:54,480
just before we do the deorbit burn so at

6049
05:18:57,510 --> 05:18:56,240
the same time they

6050
05:18:58,470 --> 05:18:57,520
flush the

6051
05:19:00,948 --> 05:18:58,480
cabin

6052
05:19:02,868 --> 05:19:00,958
atmosphere itself with some cool down

6053
05:19:04,948 --> 05:19:02,878
air they'll flow some cooled air through

6054
05:19:07,510 --> 05:19:04,958
the suits just to help regulate the

6055
05:19:09,430 --> 05:19:07,520
temperature the cooling effect inside

6056
05:19:11,270 --> 05:19:09,440
the capsule just to make sure the

6057
05:19:13,270 --> 05:19:11,280
environment stays at a comfortable

6058
05:19:15,590 --> 05:19:13,280
temperature for them while the dragon

6059
05:19:19,910 --> 05:19:15,600
capsule itself heats up to about 3 500

6060
05:19:22,948 --> 05:19:21,590
so we got about a minute left in this

6061
05:19:24,310 --> 05:19:22,958
suit leak check we'll wait for the

6062
05:19:26,948 --> 05:19:24,320
results on that

6063
05:19:29,670 --> 05:19:26,958
and we'll just be one more box checked

6064
05:19:32,310 --> 05:19:29,680
on our way to the upcoming

6065
05:19:41,510 --> 05:19:32,320
trunk step deorbit burn re-entry and

6066
05:19:45,990 --> 05:19:44,230
and one interesting thing to note if

6067
05:19:47,670 --> 05:19:46,000
you're watching this ground track you're

6068
05:19:49,910 --> 05:19:47,680
gonna start to see

6069
05:19:52,708 --> 05:19:49,920
uh that line coming out of the bottom

6070
05:19:55,190 --> 05:19:52,718
left corner and ending in the gulf

6071
05:19:57,830 --> 05:19:55,200
that's that means we are on our final

6072
05:19:59,990 --> 05:19:57,840
orbit and so

6073
05:20:01,670 --> 05:20:00,000
dragon's basically on its last lap

6074
05:20:04,470 --> 05:20:01,680
around planet earth

6075
05:20:05,430 --> 05:20:04,480
the last 90 minutes it's going to spend

6076
05:20:07,990 --> 05:20:05,440
until

6077
05:20:09,590 --> 05:20:08,000
we just about get to that splashdown so

6078
05:20:11,430 --> 05:20:09,600
you can keep an eye on that the line's

6079
05:20:13,110 --> 05:20:11,440
going to stop moving

6080
05:20:20,150 --> 05:20:13,120
where you can see it terminate in the

6081
05:20:20,160 --> 05:20:34,310
dragon spacex we show nominal leak check

6082
05:20:34,320 --> 05:21:38,230
caffeine

6083
05:21:42,070 --> 05:21:39,590
so there a minute ago we had

6084
05:21:44,548 --> 05:21:42,080
confirmation of nominal leak check again

6085
05:21:47,510 --> 05:21:44,558
that's just checking another box off on

6086
05:21:51,190 --> 05:21:47,520
the to-do list as bob and doug continue

6087
05:21:53,670 --> 05:21:51,200
their return home back to planet earth

6088
05:21:55,910 --> 05:21:53,680
up next we will be making sure that the

6089
05:21:59,030 --> 05:21:55,920
nitrox system is safe

6090
05:22:02,948 --> 05:21:59,040
and that we are able to proceed into

6091
05:22:06,230 --> 05:22:02,958
the next phases of our of our

6092
05:22:09,270 --> 05:22:06,240
descent to the

6093
05:22:11,750 --> 05:22:09,280
the gulf of mexico we are aiming for

6094
05:22:15,190 --> 05:22:11,760
a splashdown site just off the coast of

6095
05:22:17,350 --> 05:22:15,200
pensacola florida right now our recovery

6096
05:22:19,830 --> 05:22:17,360
ship is in route

6097
05:22:22,310 --> 05:22:19,840
to that designated location zone and it

6098
05:22:37,990 --> 05:22:22,320
will be there ready and waiting for bob

6099
05:22:42,310 --> 05:22:40,150
there your screen we do have a live shot

6100
05:22:44,548 --> 05:22:42,320
from go navigator again that's our

6101
05:22:45,830 --> 05:22:44,558
recovery ship located in the gulf of

6102
05:22:48,070 --> 05:22:45,840
mexico

6103
05:22:49,590 --> 05:22:48,080
you can get a little bit of a feel for

6104
05:22:52,070 --> 05:22:49,600
that wave action that we got there

6105
05:22:54,150 --> 05:22:52,080
generally speaking pretty calm looking

6106
05:22:55,990 --> 05:22:54,160
based on the waves that we can see there

6107
05:22:58,788 --> 05:22:56,000
in the shot

6108
05:23:01,190 --> 05:22:58,798
and yeah so we're excited to be able to

6109
05:23:03,830 --> 05:23:01,200
welcome bob and doug back home

6110
05:23:05,990 --> 05:23:03,840
just checking my timeline quickly

6111
05:23:07,190 --> 05:23:06,000
their

6112
05:23:09,030 --> 05:23:07,200
landing

6113
05:23:10,628 --> 05:23:09,040
will be coming up in just under two

6114
05:23:13,030 --> 05:23:10,638
hours we're looking at

6115
05:23:16,150 --> 05:23:13,040
an hour and 57 minutes

6116
05:23:17,708 --> 05:23:16,160
that will be happening at 11 48 a.m

6117
05:23:21,430 --> 05:23:17,718
pacific time

6118
05:23:25,110 --> 05:23:21,440
1848 universal coordinated time

6119
05:23:27,270 --> 05:23:25,120
before we get to their water landing

6120
05:23:29,270 --> 05:23:27,280
we have to perform a couple of steps

6121
05:23:30,788 --> 05:23:29,280
prior to that if you've been following

6122
05:23:33,270 --> 05:23:30,798
along with us this morning you're

6123
05:23:35,270 --> 05:23:33,280
probably very familiar with this

6124
05:23:36,788 --> 05:23:35,280
but for perhaps those of those of you

6125
05:23:37,670 --> 05:23:36,798
who have joined in within the last few

6126
05:23:39,830 --> 05:23:37,680
minutes

6127
05:23:43,350 --> 05:23:39,840
at this point we are exactly an hour

6128
05:23:46,150 --> 05:23:43,360
away from the next physical milestone

6129
05:23:47,830 --> 05:23:46,160
that needs to be completed prior to

6130
05:23:49,350 --> 05:23:47,840
dragon endeavour's return to planet

6131
05:23:51,910 --> 05:23:49,360
earth

6132
05:23:55,830 --> 05:23:51,920
those activities will begin with claw

6133
05:23:58,390 --> 05:23:55,840
separation the claw is what connects the

6134
05:23:59,430 --> 05:23:58,400
umbilicals the power the telemetry the

6135
05:24:03,190 --> 05:23:59,440
fluids

6136
05:24:04,548 --> 05:24:03,200
between the dragon capsule and its trunk

6137
05:24:06,470 --> 05:24:04,558
in order to

6138
05:24:09,190 --> 05:24:06,480
expose the

6139
05:24:11,110 --> 05:24:09,200
heat shield in preparation for

6140
05:24:13,750 --> 05:24:11,120
dragon's re-entry through the atmosphere

6141
05:24:15,830 --> 05:24:13,760
we need to jettison the trunk it will

6142
05:24:17,510 --> 05:24:15,840
disintegrate upon entering the earth's

6143
05:24:20,070 --> 05:24:17,520
atmosphere itself

6144
05:24:22,470 --> 05:24:20,080
so once we separate that

6145
05:24:25,750 --> 05:24:22,480
we're now able to step into what's

6146
05:24:27,750 --> 05:24:25,760
called slew to deorbit burn attitude

6147
05:24:29,590 --> 05:24:27,760
that's essentially maneuvering the

6148
05:24:32,628 --> 05:24:29,600
capsule into position

6149
05:24:36,150 --> 05:24:32,638
to perform the deorbit burn the deorbit

6150
05:24:38,310 --> 05:24:36,160
burn is where we fire the four draco

6151
05:24:39,510 --> 05:24:38,320
thrusters that are located at the top of

6152
05:24:41,750 --> 05:24:39,520
the capsule

6153
05:24:44,310 --> 05:24:41,760
near the forward hatch we call those the

6154
05:24:46,310 --> 05:24:44,320
forward bulkhead draco thrusters those

6155
05:24:47,350 --> 05:24:46,320
will be utilized to perform the deorbit

6156
05:24:48,310 --> 05:24:47,360
burn

6157
05:24:51,190 --> 05:24:48,320
it'll

6158
05:24:53,030 --> 05:24:51,200
last about 11 and a half minutes that

6159
05:24:55,430 --> 05:24:53,040
deorbit burn is what will be placing

6160
05:24:58,070 --> 05:24:55,440
dragon in its final trajectory to the

6161
05:25:00,470 --> 05:24:58,080
exact landing location so like i said

6162
05:25:01,430 --> 05:25:00,480
that'll be about 11 and a half minutes

6163
05:25:04,230 --> 05:25:01,440
long

6164
05:25:06,948 --> 05:25:04,240
after that burn completes we want to

6165
05:25:08,470 --> 05:25:06,958
close the nose cone and lock it up like

6166
05:25:10,470 --> 05:25:08,480
i said that's where the forward hatch is

6167
05:25:12,390 --> 05:25:10,480
located and since these capsules are

6168
05:25:14,470 --> 05:25:12,400
designed to be reusable we definitely

6169
05:25:16,470 --> 05:25:14,480
want to protect those thrusters and that

6170
05:25:18,310 --> 05:25:16,480
hatch because that is the hatch where

6171
05:25:20,868 --> 05:25:18,320
the astronauts

6172
05:25:22,470 --> 05:25:20,878
basically exit and enter the capsule

6173
05:25:24,868 --> 05:25:22,480
when they're going in and out of the

6174
05:25:27,350 --> 05:25:24,878
international space station so once we

6175
05:25:30,470 --> 05:25:27,360
have that nose cone uh locked and in

6176
05:25:32,948 --> 05:25:30,480
place we then enter uh we begin to enter

6177
05:25:38,150 --> 05:25:32,958
the earth's atmosphere and yeah

6178
05:25:38,160 --> 05:25:42,390
go ahead

6179
05:25:47,350 --> 05:25:44,868
okay first off for timing showing no

6180
05:25:48,948 --> 05:25:47,360
changes your tablet and onboard times on

6181
05:25:50,948 --> 05:25:48,958
your timeline are within about one

6182
05:25:56,548 --> 05:25:50,958
minute or less of our ground estimates

6183
05:26:03,510 --> 05:26:00,150
happy timing our board is

6184
05:26:06,230 --> 05:26:03,520
for the ipads and within a minute

6185
05:26:07,910 --> 05:26:06,240
and even better the onboard

6186
05:26:09,430 --> 05:26:07,920
countdown in your timeline should be

6187
05:26:11,750 --> 05:26:09,440
within a few should be within a few

6188
05:26:13,670 --> 05:26:11,760
seconds so looking pretty good

6189
05:26:15,190 --> 05:26:13,680
for the vehicle endeavor is looking

6190
05:26:17,350 --> 05:26:15,200
great for entry

6191
05:26:19,750 --> 05:26:17,360
the ready com during bomb's com check

6192
05:26:28,230 --> 05:26:19,760
earlier we consider temporary and we are

6193
05:26:33,990 --> 05:26:29,910
the endeavor's in good shape and good

6194
05:26:38,868 --> 05:26:35,910
okay as far as recovery goes go

6195
05:26:40,470 --> 05:26:38,878
navigator is uh just about uh at the

6196
05:26:43,030 --> 05:26:40,480
recover in position so within a few

6197
05:26:45,750 --> 05:26:43,040
kilometers in addition the wb is

6198
05:26:52,548 --> 05:26:45,760
airborne her tech recovery team is a go

6199
05:26:56,628 --> 05:26:54,948
go for recovery copy off

6200
05:26:58,868 --> 05:26:56,638
and one quick go back recovery has

6201
05:27:00,788 --> 05:26:58,878
arrived so they are on station

6202
05:27:02,470 --> 05:27:00,798
um in addition for the weather i'm

6203
05:27:05,030 --> 05:27:02,480
looking at the weather right now from go

6204
05:27:07,030 --> 05:27:05,040
or the water video from a go navigator

6205
05:27:09,030 --> 05:27:07,040
and it looks like glass it's awesome

6206
05:27:11,830 --> 05:27:09,040
uh the latest splashdown forecast though

6207
05:27:13,990 --> 05:27:11,840
is a winds at two decimal two five knots

6208
05:27:21,270 --> 05:27:14,000
wave height less than a foot and a six

6209
05:27:21,280 --> 05:27:32,470
happy winds waves of weather

6210
05:27:37,590 --> 05:27:35,670
all right so there we heard the deorbit

6211
05:27:38,390 --> 05:27:37,600
briefing this is basically the

6212
05:27:41,590 --> 05:27:38,400
opportunity

6213
05:27:43,030 --> 05:27:41,600
that the core here

6214
05:27:44,470 --> 05:27:43,040
okay that's all we got for the burn

6215
05:27:49,910 --> 05:27:44,480
brief we'll talk to you shortly before

6216
05:27:53,670 --> 05:27:51,670
happy all thanks mike

6217
05:27:55,430 --> 05:27:53,680
and uh correction there we'll have the

6218
05:28:01,910 --> 05:27:55,440
go no go for you shortly that'll be the

6219
05:28:01,920 --> 05:28:06,070
okay

6220
05:28:09,910 --> 05:28:08,310
yeah so as i was saying the the burn

6221
05:28:11,990 --> 05:28:09,920
briefing there just making sure that

6222
05:28:14,788 --> 05:28:12,000
everyone's on the same page since bob

6223
05:28:17,990 --> 05:28:14,798
and doug's primary primary role during

6224
05:28:20,390 --> 05:28:18,000
re-entry is to monitor telemetry timing

6225
05:28:23,430 --> 05:28:20,400
uh and data it is important to make sure

6226
05:28:25,830 --> 05:28:23,440
that their onboard timers are

6227
05:28:27,990 --> 05:28:25,840
basically time listings are synced with

6228
05:28:30,390 --> 05:28:28,000
the most recent trajectory simulations

6229
05:28:31,910 --> 05:28:30,400
that we've generated here uh in in

6230
05:28:34,470 --> 05:28:31,920
mission control so that's what that was

6231
05:28:36,948 --> 05:28:34,480
just making sure that their their

6232
05:28:39,830 --> 05:28:36,958
sequence of events was lining up

6233
05:28:43,750 --> 05:28:39,840
with the uh with what we're seeing down

6234
05:28:45,270 --> 05:28:43,760
here uh in in mission control so uh

6235
05:28:47,110 --> 05:28:45,280
all really good stuff there we also

6236
05:28:49,350 --> 05:28:47,120
heard that the recovery vessel go

6237
05:28:51,430 --> 05:28:49,360
navigator is in position

6238
05:28:54,150 --> 05:28:51,440
so it is ready and waiting for

6239
05:28:57,110 --> 05:28:54,160
splashdown which like i said before uh

6240
05:28:59,830 --> 05:28:57,120
will be occurring at 11 48 am pacific

6241
05:29:01,910 --> 05:28:59,840
1848 universal and we're just under two

6242
05:29:04,070 --> 05:29:01,920
hours from that happening so i don't

6243
05:29:06,070 --> 05:29:04,080
know about you dan but as we're stepping

6244
05:29:07,750 --> 05:29:06,080
into these checks and these and uh you

6245
05:29:09,430 --> 05:29:07,760
know we did the leak check we did have

6246
05:29:11,510 --> 05:29:09,440
done a couple of comm checks and now

6247
05:29:13,110 --> 05:29:11,520
we're talking about deorbit burn

6248
05:29:15,110 --> 05:29:13,120
my heart's starting to go we're getting

6249
05:29:17,030 --> 05:29:15,120
there it's starting to feel real we're

6250
05:29:19,510 --> 05:29:17,040
we're waking back up yes it's time to

6251
05:29:21,270 --> 05:29:19,520
bring these guys home and i mean

6252
05:29:23,110 --> 05:29:21,280
here and here in the core call up the

6253
05:29:25,430 --> 05:29:23,120
water looks like glass from the ship

6254
05:29:27,190 --> 05:29:25,440
views that's exactly the the type of

6255
05:29:29,990 --> 05:29:27,200
thing we want to hear the wind has

6256
05:29:33,030 --> 05:29:30,000
picked up a tiny bit to 2.25 knots it's

6257
05:29:35,270 --> 05:29:33,040
about 2.6 a little under 2.6 miles per

6258
05:29:37,350 --> 05:29:35,280
hour so still well within our margins

6259
05:29:39,670 --> 05:29:37,360
for what we were looking for for except

6260
05:29:41,910 --> 05:29:39,680
acceptable splashdown weather

6261
05:29:43,510 --> 05:29:41,920
right now in the room behind us and over

6262
05:29:45,990 --> 05:29:43,520
in mission control houston teams are

6263
05:29:47,590 --> 05:29:46,000
just doing a final go no go and so that

6264
05:29:49,190 --> 05:29:47,600
should wrap up over the next couple of

6265
05:29:51,190 --> 05:29:49,200
minutes and then we'll hear them call

6266
05:29:54,390 --> 05:29:51,200
that up to the crew members when they

6267
05:29:55,670 --> 05:29:54,400
get the final go to do the d orbit burn

6268
05:29:58,230 --> 05:29:55,680
but we'll be

6269
05:30:00,548 --> 05:29:58,240
doing all of the other activities prior

6270
05:30:02,230 --> 05:30:00,558
to that including the claw and trunk

6271
05:30:03,990 --> 05:30:02,240
separation and then just getting

6272
05:30:05,350 --> 05:30:04,000
ourselves ready for the orbit burn so

6273
05:30:06,548 --> 05:30:05,360
things are definitely going to start

6274
05:30:08,628 --> 05:30:06,558
picking up

6275
05:30:10,948 --> 05:30:08,638
in the next couple of minutes really the

6276
05:30:12,390 --> 05:30:10,958
next hour is real is really where things

6277
05:30:15,750 --> 05:30:12,400
start to happen

6278
05:30:18,070 --> 05:30:15,760
um but we we do have a couple of moments

6279
05:30:20,788 --> 05:30:18,080
now to get joined by a special guest

6280
05:30:24,390 --> 05:30:20,798
dragon spacex is go for the deorbit burn

6281
05:30:26,948 --> 05:30:24,400
and the burn has been enabled

6282
05:30:29,350 --> 05:30:26,958
that's a great call to hear

6283
05:30:32,310 --> 05:30:29,360
never cathy go for the european burden

6284
05:30:36,628 --> 05:30:34,310
all right so we just heard it that means

6285
05:30:39,110 --> 05:30:36,638
uh both the spacex and nasa teams are go

6286
05:30:40,628 --> 05:30:39,120
for deorbit burn so we are

6287
05:30:42,708 --> 05:30:40,638
counting down to that that you already

6288
05:30:44,470 --> 05:30:42,718
burned uh still a bit of a ways off it's

6289
05:30:46,310 --> 05:30:44,480
just under an hour from now from

6290
05:30:48,788 --> 05:30:46,320
starting for that 11 and a half minute

6291
05:30:51,830 --> 05:30:48,798
burn but for now as we are go for

6292
05:30:53,350 --> 05:30:51,840
deorbit and return of bob and doug we're

6293
05:30:55,670 --> 05:30:53,360
going to send it over to

6294
05:30:57,510 --> 05:30:55,680
the the johnson space center real quick

6295
05:31:00,548 --> 05:30:57,520
where courtney beasley is standing by in

6296
05:31:02,788 --> 05:31:00,558
mission control houston along with

6297
05:31:08,230 --> 05:31:02,798
nasa administrator jim bridenstine also

6298
05:31:12,948 --> 05:31:10,470
thanks dan yes joining me in a studio

6299
05:31:15,510 --> 05:31:12,958
here at nasa's johnson space center is

6300
05:31:17,350 --> 05:31:15,520
nasa administrator jim bridenstine jim

6301
05:31:19,990 --> 05:31:17,360
thanks for joining us today another

6302
05:31:21,990 --> 05:31:20,000
historic day for our agency returning

6303
05:31:24,628 --> 05:31:22,000
humans to earth in a commercially built

6304
05:31:26,708 --> 05:31:24,638
and operated spacecraft how is this

6305
05:31:29,190 --> 05:31:26,718
mission paving the way for the future

6306
05:31:31,510 --> 05:31:29,200
well it's a great question and i i think

6307
05:31:33,350 --> 05:31:31,520
it's really establishing the business

6308
05:31:35,750 --> 05:31:33,360
model for the future so you can see

6309
05:31:37,030 --> 05:31:35,760
today i'm wearing my artemis shirt

6310
05:31:39,830 --> 05:31:37,040
and when we go to the moon we're going

6311
05:31:41,750 --> 05:31:39,840
to go with commercial partners

6312
05:31:43,350 --> 05:31:41,760
and you know nasa's goal here we don't

6313
05:31:45,590 --> 05:31:43,360
want to purchase own and operate the

6314
05:31:47,990 --> 05:31:45,600
hardware the way we used to we want to

6315
05:31:50,390 --> 05:31:48,000
be one customer of many customers in a

6316
05:31:52,150 --> 05:31:50,400
very robust commercial marketplace

6317
05:31:54,150 --> 05:31:52,160
in low earth orbit but we also want to

6318
05:31:56,230 --> 05:31:54,160
have numerous providers that are

6319
05:31:58,230 --> 05:31:56,240
competing against each other on cost and

6320
05:32:00,948 --> 05:31:58,240
innovation and safety

6321
05:32:03,110 --> 05:32:00,958
and really create this virtuous cycle of

6322
05:32:05,670 --> 05:32:03,120
of economic development and capability

6323
05:32:07,990 --> 05:32:05,680
and that's um that's what today's

6324
05:32:10,548 --> 05:32:08,000
return is going to represent is this is

6325
05:32:12,628 --> 05:32:10,558
the next era in human space flight where

6326
05:32:14,470 --> 05:32:12,638
nasa gets to be the customer

6327
05:32:16,070 --> 05:32:14,480
we want to be a strong customer we want

6328
05:32:17,590 --> 05:32:16,080
to be a great partner

6329
05:32:21,750 --> 05:32:17,600
but we don't want to be the only ones

6330
05:32:25,830 --> 05:32:24,070
and while on board bob and doug were of

6331
05:32:27,430 --> 05:32:25,840
course conducting science experiments

6332
05:32:29,670 --> 05:32:27,440
and spacewalks

6333
05:32:31,510 --> 05:32:29,680
and how are nasa's efforts on this

6334
05:32:33,430 --> 05:32:31,520
station contributing to life back here

6335
05:32:35,030 --> 05:32:33,440
on earth

6336
05:32:37,510 --> 05:32:35,040
so when we think about the international

6337
05:32:39,270 --> 05:32:37,520
space station um it really is focused on

6338
05:32:41,110 --> 05:32:39,280
how do we do those transformational

6339
05:32:42,548 --> 05:32:41,120
activities that benefit human life here

6340
05:32:44,788 --> 05:32:42,558
on earth and

6341
05:32:47,910 --> 05:32:44,798
uh certainly um you know when we think

6342
05:32:49,990 --> 05:32:47,920
about advanced uh advanced materials

6343
05:32:51,590 --> 05:32:50,000
industrialized biomedicine these are the

6344
05:32:53,750 --> 05:32:51,600
things that we're developing every day

6345
05:32:55,670 --> 05:32:53,760
some examples would include as far as

6346
05:32:58,230 --> 05:32:55,680
advanced materials very very thin

6347
05:33:00,390 --> 05:32:58,240
materials like an artificial retina for

6348
05:33:02,470 --> 05:33:00,400
the human eyeball so somebody who has

6349
05:33:04,628 --> 05:33:02,480
macular degeneration might not have to

6350
05:33:06,788 --> 05:33:04,638
lose their eyesight in the future

6351
05:33:08,708 --> 05:33:06,798
we can only create materials that thin

6352
05:33:11,270 --> 05:33:08,718
in the microgravity of space we cannot

6353
05:33:13,190 --> 05:33:11,280
do it here in the gravity well of earth

6354
05:33:15,030 --> 05:33:13,200
but that's just one of so many examples

6355
05:33:16,788 --> 05:33:15,040
when we think about how we compound

6356
05:33:17,830 --> 05:33:16,798
pharmaceuticals when we think about how

6357
05:33:19,830 --> 05:33:17,840
we

6358
05:33:21,430 --> 05:33:19,840
you know create immunizations for things

6359
05:33:23,750 --> 05:33:21,440
like salmonella

6360
05:33:25,990 --> 05:33:23,760
and other diseases

6361
05:33:28,070 --> 05:33:26,000
these are capabilities that are

6362
05:33:30,310 --> 05:33:28,080
available to us because of the resource

6363
05:33:32,150 --> 05:33:30,320
that is microgravity

6364
05:33:34,868 --> 05:33:32,160
but you know advanced materials things

6365
05:33:37,350 --> 05:33:34,878
like very pristine fiber optic cables we

6366
05:33:38,868 --> 05:33:37,360
call it zbland for example these are all

6367
05:33:41,430 --> 05:33:38,878
things that we think that there is a

6368
05:33:43,190 --> 05:33:41,440
marketplace for the future so look right

6369
05:33:45,190 --> 05:33:43,200
now we're doing commercial resupply of

6370
05:33:47,830 --> 05:33:45,200
the international space station

6371
05:33:50,310 --> 05:33:47,840
as of today when bob and doug come home

6372
05:33:52,310 --> 05:33:50,320
safely we will be doing commercial crew

6373
05:33:54,310 --> 05:33:52,320
to the international space station the

6374
05:33:56,708 --> 05:33:54,320
next big thing is we need commercial

6375
05:33:58,070 --> 05:33:56,718
space stations themselves and in order

6376
05:34:00,070 --> 05:33:58,080
to create the market for commercial

6377
05:34:02,470 --> 05:34:00,080
space stations we have to have these

6378
05:34:04,868 --> 05:34:02,480
transformational capabilities that come

6379
05:34:06,230 --> 05:34:04,878
from the microgravity environment and

6380
05:34:08,868 --> 05:34:06,240
that's really what we're developing

6381
05:34:13,750 --> 05:34:11,430
and as you know a big day for nasa today

6382
05:34:16,628 --> 05:34:13,760
but how about a big week this week alone

6383
05:34:18,150 --> 05:34:16,638
we launched mars 2020 artemis one's

6384
05:34:20,390 --> 05:34:18,160
launch vehicle stage adapter was

6385
05:34:22,070 --> 05:34:20,400
delivered to kennedy space center and

6386
05:34:24,548 --> 05:34:22,080
here we are completing the first

6387
05:34:26,708 --> 05:34:24,558
commercial commercially crude mission to

6388
05:34:28,470 --> 05:34:26,718
the international space station what are

6389
05:34:29,670 --> 05:34:28,480
your thoughts on the state of the agency

6390
05:34:32,150 --> 05:34:29,680
at this point

6391
05:34:34,310 --> 05:34:32,160
so make no mistake uh nasa's budget

6392
05:34:37,270 --> 05:34:34,320
right now is the highest it's ever been

6393
05:34:39,190 --> 05:34:37,280
in nominal dollars um and and it's said

6394
05:34:40,868 --> 05:34:39,200
you know 22 billion dollars the budget

6395
05:34:42,390 --> 05:34:40,878
request that president trump gave us

6396
05:34:45,910 --> 05:34:42,400
that is before the house and the senate

6397
05:34:47,990 --> 05:34:45,920
right now is 25.2 billion dollars it's

6398
05:34:49,590 --> 05:34:48,000
not just about sustaining you know

6399
05:34:51,430 --> 05:34:49,600
capabilities like commercial crew

6400
05:34:52,470 --> 05:34:51,440
commercial resupply the international

6401
05:34:53,990 --> 05:34:52,480
space station

6402
05:34:55,670 --> 05:34:54,000
it's also about developing new

6403
05:34:58,310 --> 05:34:55,680
capabilities so that the united states

6404
05:35:00,470 --> 05:34:58,320
of america can stay the preeminent space

6405
05:35:02,310 --> 05:35:00,480
faring nation it's why we created the

6406
05:35:04,868 --> 05:35:02,320
artemis program to go to the moon

6407
05:35:07,030 --> 05:35:04,878
sustainably with commercial partners and

6408
05:35:09,510 --> 05:35:07,040
international partners to use the

6409
05:35:11,590 --> 05:35:09,520
resources of of the moon to live and

6410
05:35:14,150 --> 05:35:11,600
work for long periods of time and then

6411
05:35:16,470 --> 05:35:14,160
take all of that knowledge onto mars and

6412
05:35:18,150 --> 05:35:16,480
of course as you mentioned on thursday

6413
05:35:19,830 --> 05:35:18,160
you know we launched

6414
05:35:21,750 --> 05:35:19,840
that you know another mars mission the

6415
05:35:24,150 --> 05:35:21,760
most sophisticated robot that nasa has

6416
05:35:26,150 --> 05:35:24,160
ever developed is right now on its way

6417
05:35:28,150 --> 05:35:26,160
to mars and we're going to prove that we

6418
05:35:30,310 --> 05:35:28,160
can turn the carbon dioxide atmosphere

6419
05:35:31,910 --> 05:35:30,320
of mars into pure oxygen for life

6420
05:35:34,470 --> 05:35:31,920
support but there's so many other things

6421
05:35:37,270 --> 05:35:34,480
we're looking for life on another world

6422
05:35:38,548 --> 05:35:37,280
we're looking for signs of ancient life

6423
05:35:40,548 --> 05:35:38,558
on mars

6424
05:35:42,708 --> 05:35:40,558
we're talking about microbial life but

6425
05:35:44,628 --> 05:35:42,718
life nonetheless and

6426
05:35:46,868 --> 05:35:44,638
this is this is really a bright moment

6427
05:35:49,030 --> 05:35:46,878
for nasa i want to be clear though

6428
05:35:50,548 --> 05:35:49,040
we need support from our members of

6429
05:35:51,830 --> 05:35:50,558
congress in both the house and the

6430
05:35:54,470 --> 05:35:51,840
senate

6431
05:35:56,708 --> 05:35:54,480
we need to be able to get that 25.2

6432
05:35:57,990 --> 05:35:56,718
billion dollar budget that we have

6433
05:35:59,750 --> 05:35:58,000
requested

6434
05:36:01,670 --> 05:35:59,760
and so i'm working with members of

6435
05:36:03,270 --> 05:36:01,680
congress and senators on both sides of

6436
05:36:05,350 --> 05:36:03,280
the aisle every day

6437
05:36:06,948 --> 05:36:05,360
doing town halls across the country we

6438
05:36:09,030 --> 05:36:06,958
are in great shape

6439
05:36:11,030 --> 05:36:09,040
but in order to stay number one in the

6440
05:36:13,110 --> 05:36:11,040
world uh we're gonna need we're gonna

6441
05:36:16,070 --> 05:36:13,120
need the resources that the president

6442
05:36:17,590 --> 05:36:16,080
has requested

6443
05:36:19,510 --> 05:36:17,600
thanks for joining us today such an

6444
05:36:22,070 --> 05:36:19,520
exciting day and in case you missed it

6445
05:36:24,470 --> 05:36:22,080
just moments ago both spacex and nasa

6446
05:36:26,150 --> 05:36:24,480
are both a go for deorbit burn so with

6447
05:36:29,350 --> 05:36:26,160
that we'll send it back to dan and kate

6448
05:36:31,190 --> 05:36:29,360
at hawthorne for the latest

6449
05:36:33,430 --> 05:36:31,200
all right thank you so much courtney

6450
05:36:34,310 --> 05:36:33,440
great to hear from the administrator

6451
05:36:36,150 --> 05:36:34,320
and

6452
05:36:37,830 --> 05:36:36,160
we're we're in it now we're we're kind

6453
05:36:39,350 --> 05:36:37,840
of in the final stretch this is what i

6454
05:36:41,430 --> 05:36:39,360
feel like we've been waiting for for the

6455
05:36:42,708 --> 05:36:41,440
last couple of hours and it feels pretty

6456
05:36:44,548 --> 05:36:42,718
great to be here

6457
05:36:46,948 --> 05:36:44,558
yeah it certainly does

6458
05:36:49,750 --> 05:36:46,958
in this next phase of the mission dragon

6459
05:36:51,990 --> 05:36:49,760
has a series of steps to complete before

6460
05:36:53,670 --> 05:36:52,000
returning bob and doug home

6461
05:36:56,470 --> 05:36:53,680
as you've heard us talk a little bit so

6462
05:36:59,030 --> 05:36:56,480
far this morning dragon will maneuver to

6463
05:37:01,270 --> 05:36:59,040
the correct attitude and jettison is

6464
05:37:04,070 --> 05:37:01,280
trunk which is the cylindrical

6465
05:37:05,510 --> 05:37:04,080
unpressurized part of the

6466
05:37:07,430 --> 05:37:05,520
of the assembly

6467
05:37:10,230 --> 05:37:07,440
we need to expose the heat shield in

6468
05:37:12,548 --> 05:37:10,240
order to prepare the capsule for

6469
05:37:14,150 --> 05:37:12,558
atmospheric re-entry so

6470
05:37:15,830 --> 05:37:14,160
we will

6471
05:37:17,430 --> 05:37:15,840
oh there we got a nice view of bob and

6472
05:37:19,030 --> 05:37:17,440
doug in their suits this is the first

6473
05:37:20,788 --> 05:37:19,040
time we've seen them in their suits and

6474
05:37:24,310 --> 05:37:20,798
in their chairs this morning so there

6475
05:37:27,590 --> 05:37:24,320
they are tapping away preparing uh to

6476
05:37:29,270 --> 05:37:27,600
initiate the uh deorbit sequence

6477
05:37:30,628 --> 05:37:29,280
so let's talk a little bit i'm sorry i

6478
05:37:31,910 --> 05:37:30,638
was going to say just like in the lead

6479
05:37:34,070 --> 05:37:31,920
up in the last couple of minutes we

6480
05:37:35,590 --> 05:37:34,080
heard they had good suit leak checks as

6481
05:37:37,030 --> 05:37:35,600
kate described earlier once the leak

6482
05:37:39,830 --> 05:37:37,040
checks are complete they don't keep the

6483
05:37:41,030 --> 05:37:39,840
suit pressurized so visors are open

6484
05:37:42,788 --> 05:37:41,040
they're going to have cool air running

6485
05:37:45,110 --> 05:37:42,798
through their suits and the cabin and

6486
05:37:46,390 --> 05:37:45,120
just getting ready for the ride yeah

6487
05:37:49,270 --> 05:37:46,400
whenever they are re-entering the

6488
05:37:53,270 --> 05:37:49,280
atmosphere the external temperature will

6489
05:37:55,270 --> 05:37:53,280
reach about 3 500 degrees fahrenheit the

6490
05:37:57,350 --> 05:37:55,280
internal temperature of the cabin

6491
05:37:58,470 --> 05:37:57,360
however will stay around 85 degrees

6492
05:38:00,390 --> 05:37:58,480
fahrenheit

6493
05:38:02,470 --> 05:38:00,400
we have a couple of systems in place to

6494
05:38:05,110 --> 05:38:02,480
keep it cool and comfortable for bob and

6495
05:38:06,708 --> 05:38:05,120
doug as they are returning

6496
05:38:09,110 --> 05:38:06,718
like dan just said there will be some

6497
05:38:11,190 --> 05:38:09,120
cool air flowing through their suits the

6498
05:38:13,430 --> 05:38:11,200
cabin itself will also be purged with

6499
05:38:15,270 --> 05:38:13,440
cold cooler air as well

6500
05:38:17,270 --> 05:38:15,280
so that will assist in making sure that

6501
05:38:19,110 --> 05:38:17,280
the temperature stays pretty temperate

6502
05:38:22,310 --> 05:38:19,120
uh inside the capsule

6503
05:38:24,150 --> 05:38:22,320
and i mean we're just 42 minutes and 50

6504
05:38:26,788 --> 05:38:24,160
seconds away from things really kicking

6505
05:38:29,270 --> 05:38:26,798
up and this is gonna be when we really

6506
05:38:31,270 --> 05:38:29,280
start to do uh that first maneuver to

6507
05:38:33,590 --> 05:38:31,280
get ready to jettison the trunk and then

6508
05:38:35,350 --> 05:38:33,600
we'll do that claw and trunk separation

6509
05:38:37,430 --> 05:38:35,360
and then it's time for just kind of that

6510
05:38:39,750 --> 05:38:37,440
final firing of those engines that

6511
05:38:42,788 --> 05:38:39,760
really just that downhill ride yeah

6512
05:38:44,150 --> 05:38:42,798
those uh forward bulkhead thrusters

6513
05:38:45,830 --> 05:38:44,160
there are four of them four of those

6514
05:38:48,070 --> 05:38:45,840
draco thrusters

6515
05:38:49,990 --> 05:38:48,080
there at the top of the capsule near the

6516
05:38:52,868 --> 05:38:50,000
nose cone those will be utilized to

6517
05:38:55,670 --> 05:38:52,878
perform the deorbit burn this burn is

6518
05:38:57,910 --> 05:38:55,680
what will essentially give dragon its

6519
05:39:00,310 --> 05:38:57,920
final trajectory back home

6520
05:39:01,910 --> 05:39:00,320
this is the last burn that the capsule

6521
05:39:04,548 --> 05:39:01,920
will perform if you've been following

6522
05:39:05,990 --> 05:39:04,558
along since yesterday afternoon you know

6523
05:39:08,070 --> 05:39:06,000
that there have been a number of burns

6524
05:39:10,628 --> 05:39:08,080
completed this deorbit burn will be the

6525
05:39:13,830 --> 05:39:10,638
final one it will last about 11 and a

6526
05:39:15,910 --> 05:39:13,840
half minutes after that burn completes

6527
05:39:17,590 --> 05:39:15,920
we no longer need to utilize those draco

6528
05:39:19,750 --> 05:39:17,600
thrusters and we want to protect the

6529
05:39:21,990 --> 05:39:19,760
forward hatch up there so we close the

6530
05:39:24,070 --> 05:39:22,000
nose cone and lock it up

6531
05:39:26,708 --> 05:39:24,080
we're expecting that event to happen at

6532
05:39:28,470 --> 05:39:26,718
11 11 a.m pacific

6533
05:39:31,030 --> 05:39:28,480
about

6534
05:39:34,390 --> 05:39:31,040
10 minutes or excuse me 20 minutes 25

6535
05:39:36,390 --> 05:39:34,400
minutes wow mental math on air is hard

6536
05:39:37,910 --> 05:39:36,400
25 minutes after that

6537
05:39:40,230 --> 05:39:37,920
the capsule will be re-entering the

6538
05:39:43,190 --> 05:39:40,240
earth's atmosphere and like i mentioned

6539
05:39:44,948 --> 05:39:43,200
approaching about 3500 degrees and

6540
05:39:46,948 --> 05:39:44,958
that's because

6541
05:39:49,030 --> 05:39:46,958
where we're in that heat of re-entry and

6542
05:39:51,270 --> 05:39:49,040
so that's where things will really heat

6543
05:39:52,708 --> 05:39:51,280
up for bob and doug on their re-entry uh

6544
05:39:54,788 --> 05:39:52,718
and that's where we'll have that comms

6545
05:39:56,788 --> 05:39:54,798
blackout and we actually have a twitter

6546
05:39:58,390 --> 05:39:56,798
question that's germaine to this right

6547
05:39:59,830 --> 05:39:58,400
now where stephen asked during the

6548
05:40:01,830 --> 05:39:59,840
blackout will you not be able to

6549
05:40:04,628 --> 05:40:01,840
communicate with bob and doug but you

6550
05:40:07,030 --> 05:40:04,638
will be able to track them and it's it's

6551
05:40:08,948 --> 05:40:07,040
kind of a mix we won't be able to talk

6552
05:40:11,190 --> 05:40:08,958
to bob and doug we won't be able to send

6553
05:40:13,910 --> 05:40:11,200
or receive any data from the dragon

6554
05:40:16,948 --> 05:40:13,920
spacecraft so we won't have basically

6555
05:40:18,868 --> 05:40:16,958
telemetry driven tracking but we know

6556
05:40:20,548 --> 05:40:18,878
exactly where they're going to be as

6557
05:40:22,708 --> 05:40:20,558
their orbits already been calculated

6558
05:40:24,230 --> 05:40:22,718
we've had this orbit calculated since

6559
05:40:26,948 --> 05:40:24,240
yesterday essentially it's gotten

6560
05:40:28,868 --> 05:40:26,958
fine-tuned as we've done those burns

6561
05:40:30,548 --> 05:40:28,878
but we'll know exactly where they're

6562
05:40:32,708 --> 05:40:30,558
supposed to be even though we can't

6563
05:40:34,788 --> 05:40:32,718
communicate during that time exactly and

6564
05:40:37,990 --> 05:40:34,798
even though we won't be able to send or

6565
05:40:40,230 --> 05:40:38,000
receive signals or commands or telemetry

6566
05:40:41,590 --> 05:40:40,240
dragon is designed to be fully

6567
05:40:44,070 --> 05:40:41,600
autonomous

6568
05:40:45,750 --> 05:40:44,080
at that point it is driving itself

6569
05:40:47,750 --> 05:40:45,760
anyway so there's really nothing to be

6570
05:40:50,070 --> 05:40:47,760
worried about bob and doug's primary

6571
05:40:51,590 --> 05:40:50,080
function at that point is to monitor all

6572
05:40:54,948 --> 05:40:51,600
of the telemetry that they see on their

6573
05:40:59,110 --> 05:40:54,958
screens and to stay comfy

6574
05:41:01,670 --> 05:40:59,120
yeah and uh once they're through that

6575
05:41:03,590 --> 05:41:01,680
uh that really that initial entry um

6576
05:41:05,990 --> 05:41:03,600
we'll have that part called entry

6577
05:41:07,830 --> 05:41:06,000
interface which we've kind of explained

6578
05:41:09,590 --> 05:41:07,840
as that's when the capsule is really

6579
05:41:11,350 --> 05:41:09,600
experiencing aerodynamics they've been

6580
05:41:13,510 --> 05:41:11,360
flying around the vacuum of space with

6581
05:41:14,230 --> 05:41:13,520
no errors so no lift drag stuff like

6582
05:41:15,830 --> 05:41:14,240
that

6583
05:41:17,910 --> 05:41:15,840
on their capsule and entry interfaces

6584
05:41:19,590 --> 05:41:17,920
where they're really starting to hit the

6585
05:41:22,150 --> 05:41:19,600
the atmosphere and it's affecting the

6586
05:41:24,310 --> 05:41:22,160
capsule and it'll continue to use its

6587
05:41:26,070 --> 05:41:24,320
draco thrusters on the service section

6588
05:41:27,270 --> 05:41:26,080
to really guide it back home yeah

6589
05:41:30,230 --> 05:41:27,280
exactly

6590
05:41:33,030 --> 05:41:30,240
so speaking of guiding it back home

6591
05:41:37,110 --> 05:41:33,040
here come the parachutes at 11 44 a.m

6592
05:41:38,708 --> 05:41:37,120
pacific or 1844 universal time we were

6593
05:41:41,430 --> 05:41:38,718
we're going to be deploying the drogue

6594
05:41:44,150 --> 05:41:41,440
parachutes strobe shoots are utilized

6595
05:41:46,070 --> 05:41:44,160
for a couple of reasons one to

6596
05:41:47,270 --> 05:41:46,080
continue to further decelerate the

6597
05:41:49,350 --> 05:41:47,280
vehicle

6598
05:41:51,030 --> 05:41:49,360
and also to stabilize it like dan said

6599
05:41:53,830 --> 05:41:51,040
it will be experiencing some of those

6600
05:41:55,990 --> 05:41:53,840
aerodynamic pressures and so we want to

6601
05:41:58,628 --> 05:41:56,000
make sure that the the capsule is well

6602
05:42:00,548 --> 05:41:58,638
and stable and before we deploy the main

6603
05:42:03,350 --> 05:42:00,558
parachutes those main shoots will be

6604
05:42:05,590 --> 05:42:03,360
deploying at 11 45 am

6605
05:42:07,830 --> 05:42:05,600
and there will be four of them those

6606
05:42:10,390 --> 05:42:07,840
will essentially deploy and it takes a

6607
05:42:12,708 --> 05:42:10,400
couple seconds for them to fully inflate

6608
05:42:14,310 --> 05:42:12,718
so it might look a little funny at first

6609
05:42:15,670 --> 05:42:14,320
but we assure you that they are working

6610
05:42:17,830 --> 05:42:15,680
properly and it just takes a couple

6611
05:42:20,628 --> 05:42:17,840
seconds for the air to continue to catch

6612
05:42:23,590 --> 05:42:20,638
in them and for them to fully expand to

6613
05:42:25,670 --> 05:42:23,600
their large rounder shape so after those

6614
05:42:27,990 --> 05:42:25,680
shoots deploy it only takes three and a

6615
05:42:31,110 --> 05:42:28,000
half minutes for bob and doug to splash

6616
05:42:34,628 --> 05:42:31,120
down that'll be occurring at 11 48 a.m

6617
05:42:37,190 --> 05:42:34,638
pacific 1848 universal and like we've

6618
05:42:39,430 --> 05:42:37,200
mentioned before our splashdown location

6619
05:42:42,390 --> 05:42:39,440
is off the coast off the western coast

6620
05:42:44,390 --> 05:42:42,400
of florida we're aiming for a location

6621
05:42:47,910 --> 05:42:44,400
near pensacola

6622
05:42:50,390 --> 05:42:47,920
our recovery vessel go navigator is

6623
05:42:51,750 --> 05:42:50,400
currently in location ready and waiting

6624
05:42:53,510 --> 05:42:51,760
for splashdown they're actually going to

6625
05:42:55,430 --> 05:42:53,520
be waiting about three nautical miles

6626
05:42:57,110 --> 05:42:55,440
away from that splashdown point yeah we

6627
05:43:00,868 --> 05:42:57,120
got the call that they were on station

6628
05:43:03,510 --> 05:43:00,878
we also got the call that the nasa wb-57

6629
05:43:04,470 --> 05:43:03,520
airplane is in the air and we've

6630
05:43:06,548 --> 05:43:04,480
actually

6631
05:43:08,470 --> 05:43:06,558
seen a couple of brief spurts of video

6632
05:43:11,750 --> 05:43:08,480
that's the airborne asset that we'll

6633
05:43:14,310 --> 05:43:11,760
have that wb57 is a high altitude

6634
05:43:16,070 --> 05:43:14,320
research plane that nasa flies it's

6635
05:43:17,430 --> 05:43:16,080
outfitted with a number of imaging

6636
05:43:19,190 --> 05:43:17,440
cameras

6637
05:43:20,628 --> 05:43:19,200
the main one that we'll be seeing is an

6638
05:43:22,628 --> 05:43:20,638
infrared one

6639
05:43:24,548 --> 05:43:22,638
if you watch the demo one splashdown

6640
05:43:27,350 --> 05:43:24,558
which i'm sure you all did

6641
05:43:30,470 --> 05:43:27,360
you were able to see uh that first and

6642
05:43:31,590 --> 05:43:30,480
this is actually a glimpse of that wb57

6643
05:43:33,830 --> 05:43:31,600
camera

6644
05:43:35,750 --> 05:43:33,840
we'll be getting this back and

6645
05:43:37,830 --> 05:43:35,760
if we acquire at the same time we did

6646
05:43:39,270 --> 05:43:37,840
for demo one we were able to see the

6647
05:43:41,350 --> 05:43:39,280
capsule while it was still in that

6648
05:43:43,270 --> 05:43:41,360
atmospheric re-entry so it was just this

6649
05:43:45,030 --> 05:43:43,280
really bright light that all of the

6650
05:43:47,830 --> 05:43:45,040
sudden lit up the sky and that was the

6651
05:43:49,830 --> 05:43:47,840
first view we got of dragon and so we'll

6652
05:43:52,150 --> 05:43:49,840
use that to hopefully see

6653
05:43:53,990 --> 05:43:52,160
during the entry and then the initial

6654
05:43:56,390 --> 05:43:54,000
parachute deploys and then we'll have a

6655
05:43:59,110 --> 05:43:56,400
couple more assets on the ground or on

6656
05:44:01,270 --> 05:43:59,120
the water on the boat that will get a

6657
05:44:03,030 --> 05:44:01,280
couple more views of dragon as it

6658
05:44:04,470 --> 05:44:03,040
delivers bob and doug safely to the

6659
05:44:06,948 --> 05:44:04,480
ocean

6660
05:44:08,470 --> 05:44:06,958
yeah so as you can hear the all of this

6661
05:44:10,150 --> 05:44:08,480
excitement will be happening in pretty

6662
05:44:12,868 --> 05:44:10,160
rapid succession

6663
05:44:15,590 --> 05:44:12,878
on your screen now we can see closest to

6664
05:44:18,788 --> 05:44:15,600
the to the camera we have nasa astronaut

6665
05:44:20,390 --> 05:44:18,798
doug hurley uh he is the the pilot or

6666
05:44:22,708 --> 05:44:20,400
the commander for

6667
05:44:25,510 --> 05:44:22,718
this particular mission and then two

6668
05:44:27,750 --> 05:44:25,520
there now on the camera to the right is

6669
05:44:29,190 --> 05:44:27,760
nasa astronaut bob benkin

6670
05:44:31,430 --> 05:44:29,200
we are

6671
05:44:33,110 --> 05:44:31,440
very fondly looking forward to

6672
05:44:34,070 --> 05:44:33,120
bringing our space dads home this

6673
05:44:35,910 --> 05:44:34,080
morning

6674
05:44:37,990 --> 05:44:35,920
and it looks like like we mentioned

6675
05:44:39,750 --> 05:44:38,000
before that will be happening in about

6676
05:44:43,470 --> 05:44:39,760
an hour and a half again targeting

6677
05:44:46,708 --> 05:44:43,480
splashtown for 11 48 am pacific

6678
05:44:48,150 --> 05:44:46,718
1848 universal time but like we

6679
05:44:50,868 --> 05:44:48,160
mentioned before the action really

6680
05:44:53,910 --> 05:44:50,878
begins at the claw separation milestone

6681
05:44:56,788 --> 05:44:53,920
which is slated for 10 51 a.m pacific in

6682
05:44:59,910 --> 05:44:56,798
about 38 minutes from now so

6683
05:45:01,990 --> 05:44:59,920
again we are continuing to take

6684
05:45:05,510 --> 05:45:02,000
questions this morning through twitter

6685
05:45:09,270 --> 05:45:05,520
using the hashtag ask nasa our next

6686
05:45:11,270 --> 05:45:09,280
question comes to us from f1 fanatic

6687
05:45:13,910 --> 05:45:11,280
do the astronauts need to have face

6688
05:45:15,910 --> 05:45:13,920
masks down during re-entry that is a

6689
05:45:18,708 --> 05:45:15,920
great question various do observation

6690
05:45:21,110 --> 05:45:18,718
that those visors are in the upward

6691
05:45:23,590 --> 05:45:21,120
position so right now these suits are

6692
05:45:26,070 --> 05:45:23,600
unpressurized and bob and doug are

6693
05:45:28,708 --> 05:45:26,080
breathing just like the normal cabin air

6694
05:45:32,150 --> 05:45:28,718
those face masks are visors as we refer

6695
05:45:35,110 --> 05:45:32,160
to them do need to be lowered and locked

6696
05:45:36,788 --> 05:45:35,120
during the reentry period we need the

6697
05:45:39,590 --> 05:45:36,798
the spacesuit to be

6698
05:45:42,310 --> 05:45:39,600
fully enclosed during the more dynamic

6699
05:45:44,868 --> 05:45:42,320
elements of operations and certainly the

6700
05:45:48,070 --> 05:45:44,878
re-entry period is one of them so we'll

6701
05:45:50,470 --> 05:45:48,080
actually at one point during the

6702
05:45:52,548 --> 05:45:50,480
deorbit burn preparation

6703
05:45:54,310 --> 05:45:52,558
uh phase we will actually hear

6704
05:45:56,628 --> 05:45:54,320
communication between

6705
05:45:58,788 --> 05:45:56,638
uh ground station from ground here

6706
05:46:00,868 --> 05:45:58,798
mission control headquarters at spacex

6707
05:46:03,510 --> 05:46:00,878
to bob and doug just to confirm and

6708
05:46:06,708 --> 05:46:03,520
double check that those visors are

6709
05:46:08,548 --> 05:46:06,718
are in place where they should be

6710
05:46:09,670 --> 05:46:08,558
our next question comes to us from

6711
05:46:12,070 --> 05:46:09,680
philip

6712
05:46:13,910 --> 05:46:12,080
where exactly are the parachutes stored

6713
05:46:16,070 --> 05:46:13,920
before deployment

6714
05:46:18,150 --> 05:46:16,080
they are stored on

6715
05:46:20,310 --> 05:46:18,160
in two separate compartments on the

6716
05:46:22,390 --> 05:46:20,320
dragon spacecraft

6717
05:46:24,150 --> 05:46:22,400
on a side of the vehicle that has a

6718
05:46:26,230 --> 05:46:24,160
deployable panel

6719
05:46:27,750 --> 05:46:26,240
the drogue parachutes are stored in the

6720
05:46:29,110 --> 05:46:27,760
kind of the upper part it's called the

6721
05:46:30,948 --> 05:46:29,120
upper bulkhead

6722
05:46:33,430 --> 05:46:30,958
and they're deployed by two drogue

6723
05:46:35,910 --> 05:46:33,440
motors or mortars

6724
05:46:38,150 --> 05:46:35,920
so pyrotechnics that are fired to

6725
05:46:40,390 --> 05:46:38,160
actually deploy those drug parachutes

6726
05:46:41,990 --> 05:46:40,400
just further down the panel kind of at

6727
05:46:43,990 --> 05:46:42,000
the base of the spacecraft is where the

6728
05:46:46,150 --> 05:46:44,000
four main parachutes are stored and

6729
05:46:48,548 --> 05:46:46,160
again those get drawn out by the drogue

6730
05:46:50,230 --> 05:46:48,558
chutes there are redundant systems in

6731
05:46:52,470 --> 05:46:50,240
place to make sure

6732
05:46:54,150 --> 05:46:52,480
that if the first set of mortars don't

6733
05:46:55,670 --> 05:46:54,160
fire you have backups to get these

6734
05:46:56,708 --> 05:46:55,680
shoots deployed

6735
05:46:59,430 --> 05:46:56,718
we're

6736
05:47:01,110 --> 05:46:59,440
uh one fault tolerant on both the

6737
05:47:02,390 --> 05:47:01,120
the drug parachutes and the main

6738
05:47:04,708 --> 05:47:02,400
parachutes

6739
05:47:06,070 --> 05:47:04,718
so one out of two droves and three out

6740
05:47:07,510 --> 05:47:06,080
of four mains

6741
05:47:08,628 --> 05:47:07,520
is what the vehicle has been rated and

6742
05:47:09,910 --> 05:47:08,638
tested to

6743
05:47:12,708 --> 05:47:09,920
we've

6744
05:47:15,590 --> 05:47:12,718
spacex has done a tremendous amount of

6745
05:47:16,390 --> 05:47:15,600
testing on these parachutes even within

6746
05:47:18,390 --> 05:47:16,400
just

6747
05:47:19,590 --> 05:47:18,400
the last several months in the lead-up

6748
05:47:21,430 --> 05:47:19,600
to the mission

6749
05:47:23,510 --> 05:47:21,440
as parachutes obviously a very critical

6750
05:47:26,070 --> 05:47:23,520
part of the re-entry

6751
05:47:28,310 --> 05:47:26,080
and this is something that

6752
05:47:30,310 --> 05:47:28,320
is very meticulously packed and

6753
05:47:31,270 --> 05:47:30,320
documented before the start of any

6754
05:47:34,070 --> 05:47:31,280
mission

6755
05:47:35,430 --> 05:47:34,080
and nasa assisting spacex as we have

6756
05:47:38,310 --> 05:47:35,440
some experts who have been involved in

6757
05:47:39,590 --> 05:47:38,320
parachute missions for decades

6758
05:47:41,030 --> 05:47:39,600
but

6759
05:47:44,070 --> 05:47:41,040
the parachutes are stored under

6760
05:47:46,070 --> 05:47:44,080
deployable panels and we'll see them

6761
05:47:47,670 --> 05:47:46,080
basically fire open as the as the

6762
05:47:49,670 --> 05:47:47,680
parachutes come out and deploy at the

6763
05:47:52,628 --> 05:47:49,680
different altitudes yeah those panels

6764
05:47:54,548 --> 05:47:52,638
are basically located above and below

6765
05:47:57,030 --> 05:47:54,558
the side hatch

6766
05:48:00,070 --> 05:47:57,040
panel so if you are looking at the

6767
05:48:02,070 --> 05:48:00,080
dragon capsule uh the you know the

6768
05:48:03,030 --> 05:48:02,080
anchor point for those parachutes will

6769
05:48:07,110 --> 05:48:03,040
ensure

6770
05:48:09,510 --> 05:48:07,120
that the side hatch will effectively be

6771
05:48:11,830 --> 05:48:09,520
as far away from the ocean

6772
05:48:13,030 --> 05:48:11,840
surface as possible ensuring that we're

6773
05:48:15,190 --> 05:48:13,040
able to

6774
05:48:17,270 --> 05:48:15,200
expedite the process of

6775
05:48:19,110 --> 05:48:17,280
egressing bob and doug from the capsule

6776
05:48:20,708 --> 05:48:19,120
and the whole recovery process as a

6777
05:48:22,868 --> 05:48:20,718
whole great question

6778
05:48:24,310 --> 05:48:22,878
all right our next one comes from scott

6779
05:48:26,390 --> 05:48:24,320
he wants to know what are the tablets on

6780
05:48:28,628 --> 05:48:26,400
their legs used for what kind of devices

6781
05:48:31,190 --> 05:48:28,638
are they i think you've heard them call

6782
05:48:35,110 --> 05:48:31,200
out a few times that they're using ipads

6783
05:48:37,670 --> 05:48:35,120
on board and they're really just

6784
05:48:40,548 --> 05:48:37,680
essentially their user manuals they're

6785
05:48:42,070 --> 05:48:40,558
able to dial up different procedures uh

6786
05:48:43,350 --> 05:48:42,080
checklists things that they're looking

6787
05:48:45,030 --> 05:48:43,360
for throughout

6788
05:48:48,070 --> 05:48:45,040
their flight they get they're able to

6789
05:48:49,830 --> 05:48:48,080
velcro them essentially to their suits

6790
05:48:51,030 --> 05:48:49,840
and just like

6791
05:49:00,628 --> 05:48:51,040
the

6792
05:49:01,830 --> 05:49:00,638
information source

6793
05:49:04,868 --> 05:49:01,840
dragon

6794
05:49:06,548 --> 05:49:04,878
doesn't have the big paper manuals that

6795
05:49:07,910 --> 05:49:06,558
we were used to in the shuttle era and

6796
05:49:09,510 --> 05:49:07,920
things like that

6797
05:49:11,030 --> 05:49:09,520
just kind of streamlining everything as

6798
05:49:13,270 --> 05:49:11,040
much as possible

6799
05:49:16,230 --> 05:49:13,280
yeah absolutely like we mentioned before

6800
05:49:18,230 --> 05:49:16,240
this is a demonstration mission and so

6801
05:49:20,230 --> 05:49:18,240
bob and doug's job here is to make sure

6802
05:49:22,150 --> 05:49:20,240
that everything is working as it should

6803
05:49:24,230 --> 05:49:22,160
be so a lot of what they're doing is

6804
05:49:25,430 --> 05:49:24,240
going to simply be monitoring well not

6805
05:49:27,190 --> 05:49:25,440
simply

6806
05:49:28,470 --> 05:49:27,200
paying attention can be especially

6807
05:49:30,470 --> 05:49:28,480
whenever there's a lot going on

6808
05:49:32,470 --> 05:49:30,480
dynamically around you is staying

6809
05:49:34,150 --> 05:49:32,480
focused can be tough so it's not an easy

6810
05:49:35,910 --> 05:49:34,160
job what they have coming up but they

6811
05:49:38,150 --> 05:49:35,920
will essentially be responsible for

6812
05:49:40,150 --> 05:49:38,160
monitoring all the data and telemetry

6813
05:49:42,628 --> 05:49:40,160
that's being received on screens and

6814
05:49:44,788 --> 05:49:42,638
part of the debriefing that will happen

6815
05:49:47,590 --> 05:49:44,798
once they get back on land is quite

6816
05:49:50,230 --> 05:49:47,600
simply was there anything that happened

6817
05:49:52,628 --> 05:49:50,240
in reality that you weren't expecting or

6818
05:49:55,830 --> 05:49:52,638
differed from what you were instructed

6819
05:49:57,350 --> 05:49:55,840
would occur so making sure that in the

6820
05:49:58,548 --> 05:49:57,360
future fully

6821
05:50:00,150 --> 05:49:58,558
operational

6822
05:50:02,708 --> 05:50:00,160
missions that we have starting with crew

6823
05:50:04,708 --> 05:50:02,718
one launching later this year

6824
05:50:07,590 --> 05:50:04,718
that those crews are fully prepared and

6825
05:50:09,270 --> 05:50:07,600
that we make those essentially those

6826
05:50:11,990 --> 05:50:09,280
instruction manuals that they do have

6827
05:50:14,230 --> 05:50:12,000
access to as perfect as possible

6828
05:50:16,470 --> 05:50:14,240
because it is essential that we we have

6829
05:50:19,350 --> 05:50:16,480
correct information and that the crew is

6830
05:50:21,350 --> 05:50:19,360
informed and aware of all the operations

6831
05:50:23,350 --> 05:50:21,360
that are going on regardless of whether

6832
05:50:25,190 --> 05:50:23,360
or not they may not they're not the ones

6833
05:50:27,030 --> 05:50:25,200
necessarily commanding because the

6834
05:50:28,788 --> 05:50:27,040
vehicle is autonomous but it is

6835
05:50:30,948 --> 05:50:28,798
important that they do they do know

6836
05:50:32,708 --> 05:50:30,958
what's going on all right our next

6837
05:50:34,470 --> 05:50:32,718
question comes from sam might be the

6838
05:50:35,910 --> 05:50:34,480
most important one of the day wanted to

6839
05:50:37,510 --> 05:50:35,920
know if bob and doug can listen to the

6840
05:50:39,350 --> 05:50:37,520
spacex webcast when they're inside the

6841
05:50:41,590 --> 05:50:39,360
dragon capsule i mean i certainly hope

6842
05:50:43,350 --> 05:50:41,600
so it's not like they have too much else

6843
05:50:45,270 --> 05:50:43,360
on their mind right

6844
05:50:47,910 --> 05:50:45,280
no they're not able to listen to us but

6845
05:50:50,470 --> 05:50:47,920
one kind of fun fact that always kind of

6846
05:50:52,390 --> 05:50:50,480
makes us geek out a little bit is the

6847
05:50:55,110 --> 05:50:52,400
crew members on board the space station

6848
05:50:57,350 --> 05:50:55,120
will usually get nasa tv pumped up to

6849
05:50:59,190 --> 05:50:57,360
them anytime their crewmates are

6850
05:51:00,150 --> 05:50:59,200
launching or landing so they're able to

6851
05:51:02,230 --> 05:51:00,160
watch

6852
05:51:05,030 --> 05:51:02,240
their friends and former crewmates as of

6853
05:51:08,948 --> 05:51:05,040
just a few hours ago return home so

6854
05:51:13,990 --> 05:51:11,190
great question another one comes to us

6855
05:51:15,910 --> 05:51:14,000
from rural rocker does the dragon

6856
05:51:18,868 --> 05:51:15,920
capsule have windows where bob and doug

6857
05:51:21,670 --> 05:51:18,878
can look out absolutely actually one of

6858
05:51:23,910 --> 05:51:21,680
my favorite pictures that doug hurley

6859
05:51:25,830 --> 05:51:23,920
has posted on instagram to date was

6860
05:51:27,350 --> 05:51:25,840
actually one of the first pictures he

6861
05:51:30,470 --> 05:51:27,360
posted at the beginning of this mission

6862
05:51:32,470 --> 05:51:30,480
was a shot of what he could see outside

6863
05:51:34,868 --> 05:51:32,480
of crew dragon's windows

6864
05:51:37,030 --> 05:51:34,878
there is a window located on either side

6865
05:51:40,470 --> 05:51:37,040
of the side hatch and

6866
05:51:41,910 --> 05:51:40,480
it certainly will provide

6867
05:51:43,830 --> 05:51:41,920
visual

6868
05:51:45,670 --> 05:51:43,840
confirmation that re-entry is happening

6869
05:51:47,190 --> 05:51:45,680
like dan mentioned before they'll be

6870
05:51:50,310 --> 05:51:47,200
able to see

6871
05:51:52,948 --> 05:51:50,320
a little bit of the energy that's being

6872
05:51:55,670 --> 05:51:52,958
that's being expelled during the reentry

6873
05:51:57,670 --> 05:51:55,680
period you know some of those pieces of

6874
05:52:00,708 --> 05:51:57,680
the ablative material as they heat up

6875
05:52:02,470 --> 05:52:00,718
and are designed to flicker away they'll

6876
05:52:04,470 --> 05:52:02,480
actually be able to see that from from

6877
05:52:06,948 --> 05:52:04,480
the windows themselves so it'll be quite

6878
05:52:08,628 --> 05:52:06,958
the firework show

6879
05:52:10,708 --> 05:52:08,638
all right our next one comes from joe

6880
05:52:12,470 --> 05:52:10,718
wants to know does the dragon capsule

6881
05:52:14,390 --> 05:52:12,480
have netflix

6882
05:52:17,430 --> 05:52:14,400
another important question yeah the

6883
05:52:20,548 --> 05:52:17,440
answer to that is no as our as our views

6884
05:52:21,990 --> 05:52:20,558
here of the capsule cycle through

6885
05:52:23,750 --> 05:52:22,000
we'll be able to see what their screens

6886
05:52:25,830 --> 05:52:23,760
look like there we go so there in the

6887
05:52:28,548 --> 05:52:25,840
center screen we actually have the

6888
05:52:29,910 --> 05:52:28,558
ground tracking map as you can see

6889
05:52:32,788 --> 05:52:29,920
there actually it might be kind of hard

6890
05:52:35,510 --> 05:52:32,798
to make out but dragon is actually

6891
05:52:38,230 --> 05:52:35,520
in crossing over the atlantic ocean now

6892
05:52:40,948 --> 05:52:38,240
approaching what looks like

6893
05:52:43,750 --> 05:52:40,958
england and ireland so it will be

6894
05:52:46,070 --> 05:52:43,760
crossing over into europe soon

6895
05:52:47,750 --> 05:52:46,080
and also on those screens on to the left

6896
05:52:50,150 --> 05:52:47,760
and the right of that

6897
05:52:51,430 --> 05:52:50,160
ground track screen were their telemetry

6898
05:52:53,430 --> 05:52:51,440
screens so

6899
05:52:55,590 --> 05:52:53,440
those will be the the interface that

6900
05:52:58,788 --> 05:52:55,600
they use during the

6901
05:53:00,150 --> 05:52:58,798
uh during the deorbit burn

6902
05:53:01,590 --> 05:53:00,160
and that's what they'll essentially use

6903
05:53:04,390 --> 05:53:01,600
to make sure that everything is looking

6904
05:53:06,628 --> 05:53:04,400
good and performing nominally and i mean

6905
05:53:08,310 --> 05:53:06,638
the that center screen that you just saw

6906
05:53:10,150 --> 05:53:08,320
that's essentially the same map that

6907
05:53:11,910 --> 05:53:10,160
we've been looking at throughout our

6908
05:53:13,430 --> 05:53:11,920
coverage here today so

6909
05:53:15,350 --> 05:53:13,440
they're looking at a lot of the same

6910
05:53:16,948 --> 05:53:15,360
data that we're trying to give you guys

6911
05:53:19,350 --> 05:53:16,958
down here on the ground just where are

6912
05:53:20,788 --> 05:53:19,360
they over the earth because it can be a

6913
05:53:22,310 --> 05:53:20,798
little disorienting

6914
05:53:24,070 --> 05:53:22,320
to look out the window and figure it out

6915
05:53:26,150 --> 05:53:24,080
quickly but they're able to see just how

6916
05:53:28,548 --> 05:53:26,160
far along their orbit they are where

6917
05:53:30,390 --> 05:53:28,558
those milestones are coming up um so

6918
05:53:32,628 --> 05:53:30,400
they can just again they're they're in a

6919
05:53:35,670 --> 05:53:32,638
monitor mode and they're ready locked

6920
05:53:38,548 --> 05:53:35,680
and loaded to jump in if required

6921
05:53:41,110 --> 05:53:38,558
our next question comes from roshan who

6922
05:53:44,150 --> 05:53:41,120
uh seven-year-old ayan wants to know why

6923
05:53:46,150 --> 05:53:44,160
is the dragon capsule cone-shaped

6924
05:53:48,788 --> 05:53:46,160
for a very specific reason and that's

6925
05:53:52,070 --> 05:53:48,798
why a lot of cat or a lot of spacecraft

6926
05:53:54,548 --> 05:53:52,080
are in a capsule shape um when they were

6927
05:53:56,470 --> 05:53:54,558
trying to really figure out the most

6928
05:53:57,590 --> 05:53:56,480
efficient way to re-enter the earth's

6929
05:54:01,110 --> 05:53:57,600
atmosphere

6930
05:54:04,070 --> 05:54:01,120
um uh both from uh handling the

6931
05:54:04,948 --> 05:54:04,080
trajectory um without having

6932
05:54:08,150 --> 05:54:04,958
uh

6933
05:54:09,510 --> 05:54:08,160
wings like a space shuttle um you

6934
05:54:11,110 --> 05:54:09,520
uh

6935
05:54:13,990 --> 05:54:11,120
starting over when they were really

6936
05:54:16,548 --> 05:54:14,000
first trying to figure out how to best

6937
05:54:17,990 --> 05:54:16,558
shape a spacecraft to efficiently and

6938
05:54:20,548 --> 05:54:18,000
effectively re-enter the earth's

6939
05:54:22,390 --> 05:54:20,558
atmosphere in the safest configuration

6940
05:54:24,150 --> 05:54:22,400
where they essentially landed on was a

6941
05:54:27,670 --> 05:54:24,160
cone shape

6942
05:54:29,430 --> 05:54:27,680
or a capsule shape they they there were

6943
05:54:31,510 --> 05:54:29,440
very initial drawings that you could

6944
05:54:33,270 --> 05:54:31,520
find all manner of spacecraft that were

6945
05:54:34,230 --> 05:54:33,280
put into wind tunnels but at the end of

6946
05:54:35,990 --> 05:54:34,240
the day

6947
05:54:37,670 --> 05:54:36,000
all the way back in the early days of

6948
05:54:40,708 --> 05:54:37,680
space flight when we were in the in the

6949
05:54:43,030 --> 05:54:40,718
mercury um and uh the

6950
05:54:45,830 --> 05:54:43,040
very early days they were able to

6951
05:54:47,590 --> 05:54:45,840
determine that the capsule shape was

6952
05:54:49,670 --> 05:54:47,600
really the most efficient that shape of

6953
05:54:52,070 --> 05:54:49,680
heat shield dissipated the heat the best

6954
05:54:54,070 --> 05:54:52,080
was the easiest to control and was

6955
05:54:56,390 --> 05:54:54,080
really the safest option and physics

6956
05:54:57,670 --> 05:54:56,400
haven't changed since the 60s at least

6957
05:54:59,590 --> 05:54:57,680
not a great deal

6958
05:55:01,030 --> 05:54:59,600
so that's why you still see a lot of

6959
05:55:03,510 --> 05:55:01,040
capsule-shaped

6960
05:55:06,628 --> 05:55:03,520
spacecraft and it's really just for

6961
05:55:16,070 --> 05:55:06,638
re-entering an atmosphere

6962
05:55:20,628 --> 05:55:18,070
so there on your screen again we have

6963
05:55:22,708 --> 05:55:20,638
live shots coming from dragon endeavor

6964
05:55:25,110 --> 05:55:22,718
as it is

6965
05:55:27,990 --> 05:55:25,120
making its way back towards earth we are

6966
05:55:32,230 --> 05:55:28,000
in approaching the final steps of the

6967
05:55:36,708 --> 05:55:32,240
day of of the mission in fact uh and at

6968
05:55:38,390 --> 05:55:36,718
11 48 a.m pacific 18 18

6969
05:55:40,070 --> 05:55:38,400
a.m or

6970
05:55:41,990 --> 05:55:40,080
p.m excuse me

6971
05:55:45,030 --> 05:55:42,000
uh universal

6972
05:55:48,230 --> 05:55:45,040
we will we will have the the splashdown

6973
05:55:50,788 --> 05:55:48,240
of dragon endeavor so right now bob and

6974
05:55:53,910 --> 05:55:50,798
doug are essentially cycling through

6975
05:55:55,430 --> 05:55:53,920
preparing for what we call deorbit burn

6976
05:55:57,430 --> 05:55:55,440
initiation

6977
05:55:59,830 --> 05:55:57,440
this will be where

6978
05:56:03,030 --> 05:55:59,840
there's a the deorbit burn is is what

6979
05:56:05,990 --> 05:56:03,040
will be placing dragon on its specific

6980
05:56:09,190 --> 05:56:06,000
on its final trajectory to a specific

6981
05:56:11,590 --> 05:56:09,200
landing location uh that location has

6982
05:56:14,230 --> 05:56:11,600
was there were seven possible ones we

6983
05:56:16,390 --> 05:56:14,240
determined the best one for today's

6984
05:56:18,868 --> 05:56:16,400
re-entry uh to be off the coast of

6985
05:56:22,150 --> 05:56:18,878
florida near pensacola the recovery

6986
05:56:23,430 --> 05:56:22,160
vessel go navigator is in place ready

6987
05:56:25,670 --> 05:56:23,440
and waiting

6988
05:56:29,270 --> 05:56:25,680
uh and it seems like bob and doug are

6989
05:56:33,990 --> 05:56:31,510
they are in their spacesuits the leak

6990
05:56:35,990 --> 05:56:34,000
check has been performed and we got the

6991
05:56:37,670 --> 05:56:36,000
call out that it was nominal so

6992
05:56:39,830 --> 05:56:37,680
everything good there

6993
05:56:41,590 --> 05:56:39,840
right now those visors are in the up

6994
05:56:44,628 --> 05:56:41,600
position

6995
05:56:46,628 --> 05:56:44,638
they will be closed and locked whenever

6996
05:56:50,070 --> 05:56:46,638
we get into the dynamic portion here

6997
05:56:53,110 --> 05:56:50,080
upcoming in just a few minutes checking

6998
05:56:55,590 --> 05:56:53,120
my timeline here we're just about 24

6999
05:56:57,670 --> 05:56:55,600
minutes and 20 seconds from

7000
05:56:59,510 --> 05:56:57,680
things really picking up that's when

7001
05:57:01,030 --> 05:56:59,520
we'll start to get into the attitude to

7002
05:57:04,708 --> 05:57:01,040
separate the trunk

7003
05:57:07,270 --> 05:57:04,718
and just about eight minutes after that

7004
05:57:09,670 --> 05:57:07,280
is when we'll start the deorbit burn

7005
05:57:12,070 --> 05:57:09,680
and again that'll be the longest burn of

7006
05:57:14,548 --> 05:57:12,080
dragon's return journey

7007
05:57:17,190 --> 05:57:14,558
the latest timeline we got had it

7008
05:57:18,230 --> 05:57:17,200
lasting for about 11 minutes and 22

7009
05:57:21,430 --> 05:57:18,240
seconds

7010
05:57:23,910 --> 05:57:21,440
it'll be the last firing of those

7011
05:57:26,230 --> 05:57:23,920
forward bulkhead thrusters

7012
05:57:27,430 --> 05:57:26,240
the four dracos the very top of dragon

7013
05:57:29,910 --> 05:57:27,440
that will eventually be covered up by

7014
05:57:32,548 --> 05:57:29,920
the nose cone following the deorbit burn

7015
05:57:34,868 --> 05:57:32,558
and as we've said before that deorbit

7016
05:57:36,788 --> 05:57:34,878
burn is what commits them to coming home

7017
05:57:38,868 --> 05:57:36,798
when that happens that capsule is

7018
05:57:40,788 --> 05:57:38,878
re-entering the earth's atmosphere and

7019
05:57:42,470 --> 05:57:40,798
that'll put them

7020
05:57:44,868 --> 05:57:42,480
essentially on a collision course with

7021
05:57:45,910 --> 05:57:44,878
planet earth it lines up their their

7022
05:57:48,150 --> 05:57:45,920
orbit

7023
05:58:34,310 --> 05:57:48,160
to intersect with that splashdown point

7024
05:58:37,350 --> 05:58:35,750
and while we have

7025
05:58:39,670 --> 05:58:37,360
just a few more minutes until we get to

7026
05:58:41,270 --> 05:58:39,680
that we still have some questions coming

7027
05:58:44,868 --> 05:58:41,280
in again if you have one jump over on

7028
05:58:47,590 --> 05:58:44,878
twitter use the hashtag ask nasa

7029
05:58:49,510 --> 05:58:47,600
this one comes from scarif survivor

7030
05:58:51,350 --> 05:58:49,520
who wants to know does dragon lose radio

7031
05:58:53,430 --> 05:58:51,360
data contact with satellite or ground

7032
05:58:58,390 --> 05:58:53,440
stations during re-entry

7033
05:59:02,150 --> 05:58:59,910
as that plasma

7034
05:59:04,310 --> 05:59:02,160
builds up around the spacecraft it

7035
05:59:07,110 --> 05:59:04,320
essentially prevents signals being sent

7036
05:59:08,788 --> 05:59:07,120
or transmitted or received by dragon's

7037
05:59:11,190 --> 05:59:08,798
antennas around the outside of the

7038
05:59:13,990 --> 05:59:11,200
spacecraft so

7039
05:59:15,350 --> 05:59:14,000
it's both satellites and ground stations

7040
05:59:17,430 --> 05:59:15,360
that it won't be able to communicate

7041
05:59:18,470 --> 05:59:17,440
with but again dragon continues flying

7042
05:59:20,628 --> 05:59:18,480
itself

7043
05:59:23,190 --> 05:59:20,638
we know what its orbit is plotted out to

7044
05:59:26,070 --> 05:59:23,200
be so we know where it is and we even

7045
05:59:29,350 --> 05:59:26,080
know the expected time of that

7046
05:59:30,868 --> 05:59:29,360
blackout in about six minutes so

7047
05:59:32,708 --> 05:59:30,878
it does lose contact with everything we

7048
05:59:34,708 --> 05:59:32,718
won't be able to hear from bob and doug

7049
05:59:36,230 --> 05:59:34,718
until they're on the other side

7050
05:59:43,030 --> 05:59:36,240
of that blackout and then we'll

7051
05:59:47,270 --> 05:59:45,350
all right we have another one from

7052
05:59:49,270 --> 05:59:47,280
nettie banda

7053
05:59:50,788 --> 05:59:49,280
wanted to know how many seats are in

7054
05:59:52,548 --> 05:59:50,798
dragon

7055
05:59:53,910 --> 05:59:52,558
so as you can see on your screen there

7056
05:59:58,070 --> 05:59:53,920
there are actually

7057
06:00:01,350 --> 05:59:58,080
four chairs there available we will be

7058
06:00:02,310 --> 06:00:01,360
utilizing all four seats on the crew one

7059
06:00:04,390 --> 06:00:02,320
mission

7060
06:00:07,110 --> 06:00:04,400
launching later this year currently

7061
06:00:09,110 --> 06:00:07,120
targeted for september uh right now bob

7062
06:00:11,910 --> 06:00:09,120
and doug are only occupying two of them

7063
06:00:14,070 --> 06:00:11,920
as this is a demonstration mission so uh

7064
06:00:16,310 --> 06:00:14,080
yeah we will be utilizing all four of

7065
06:00:17,910 --> 06:00:16,320
those seats in future missions but as of

7066
06:00:20,390 --> 06:00:17,920
right now

7067
06:00:21,990 --> 06:00:20,400
i believe it was on the

7068
06:00:24,868 --> 06:00:22,000
launch portion of the mission one of

7069
06:00:27,430 --> 06:00:24,878
those seats was occupied by tremor who

7070
06:00:29,270 --> 06:00:27,440
if you've been following along is the

7071
06:00:33,510 --> 06:00:29,280
sequin dinosaur

7072
06:00:35,510 --> 06:00:33,520
that was voted on by the two sons

7073
06:00:37,430 --> 06:00:35,520
from bob and doug as

7074
06:00:40,390 --> 06:00:37,440
what should be the

7075
06:00:43,030 --> 06:00:40,400
zero g indicator so tremor was strapped

7076
06:00:45,510 --> 06:00:43,040
into a seat during ascent and when they

7077
06:00:48,948 --> 06:00:45,520
got the okay to release him he started

7078
06:00:50,948 --> 06:00:48,958
floating into the capsule and

7079
06:00:55,110 --> 06:00:50,958
you know gave us its sequined glory

7080
06:00:59,430 --> 06:00:57,750
all right well again just another time

7081
06:01:02,150 --> 06:00:59,440
hack as we're coming up on these for

7082
06:01:03,670 --> 06:01:02,160
just a little over 20 minutes from the

7083
06:01:05,990 --> 06:01:03,680
start of all of our deorbit burn

7084
06:01:08,230 --> 06:01:06,000
sequencing starting

7085
06:01:10,548 --> 06:01:08,240
so we're looking at that to really pick

7086
06:01:12,948 --> 06:01:10,558
up at about 10 48

7087
06:01:15,270 --> 06:01:12,958
as we'll start getting into the attitude

7088
06:01:17,430 --> 06:01:15,280
for trunk separation

7089
06:01:18,948 --> 06:01:17,440
and then we start

7090
06:01:20,628 --> 06:01:18,958
basically executing a bunch of steps

7091
06:01:22,310 --> 06:01:20,638
that are going to commit bob and doug to

7092
06:01:24,548 --> 06:01:22,320
this re-entry yeah we're looking forward

7093
06:01:26,948 --> 06:01:24,558
to those uh it will be it'll be quite

7094
06:01:28,868 --> 06:01:26,958
the journey now of course with respect

7095
06:01:31,030 --> 06:01:28,878
to the deorbit burn bob and doug will

7096
06:01:33,350 --> 06:01:31,040
remain in their seats and strapped in

7097
06:01:36,070 --> 06:01:33,360
for the entire duration in fact they

7098
06:01:38,948 --> 06:01:36,080
won't be exiting those seats until they

7099
06:01:41,030 --> 06:01:38,958
are being until they're able to egress

7100
06:01:43,030 --> 06:01:41,040
or exit the capsule after it has

7101
06:01:44,948 --> 06:01:43,040
splashed down and been recovered out of

7102
06:01:47,350 --> 06:01:44,958
the ocean and

7103
06:01:50,150 --> 06:01:47,360
safely resting in the nest of the

7104
06:01:53,190 --> 06:01:50,160
recovery vessel along that note our next

7105
06:01:55,510 --> 06:01:53,200
twitter question is from brett

7106
06:01:57,750 --> 06:01:55,520
the question is what is the orientation

7107
06:01:59,990 --> 06:01:57,760
of the astronauts when seated as in do

7108
06:02:02,310 --> 06:02:00,000
they face the front or the top of the

7109
06:02:04,150 --> 06:02:02,320
capsule and do they find it comfortable

7110
06:02:06,470 --> 06:02:04,160
great question there so in the views

7111
06:02:07,910 --> 06:02:06,480
that we just had a couple minutes ago

7112
06:02:09,510 --> 06:02:07,920
they were

7113
06:02:12,070 --> 06:02:09,520
i guess what we would call in the

7114
06:02:14,470 --> 06:02:12,080
reclined position they were facing

7115
06:02:16,708 --> 06:02:14,480
towards the top of the capsule

7116
06:02:19,110 --> 06:02:16,718
during the launch portion whenever they

7117
06:02:21,670 --> 06:02:19,120
were actually getting into the castle

7118
06:02:23,990 --> 06:02:21,680
back in late may the seats were actuated

7119
06:02:26,230 --> 06:02:24,000
in the down position where they were

7120
06:02:28,868 --> 06:02:26,240
facing towards the hatch

7121
06:02:31,110 --> 06:02:28,878
the angle of difference is about 40

7122
06:02:33,670 --> 06:02:31,120
degrees between the two positions they

7123
06:02:36,470 --> 06:02:33,680
actuate in order to make sure that

7124
06:02:37,670 --> 06:02:36,480
whenever there are whenever there are

7125
06:02:39,670 --> 06:02:37,680
g's being

7126
06:02:42,230 --> 06:02:39,680
experienced that it is in the most

7127
06:02:44,628 --> 06:02:42,240
comfortable and safely ergonomic way

7128
06:02:47,670 --> 06:02:44,638
possible so that's where seat or

7129
06:02:49,270 --> 06:02:47,680
actuation comes in handy also it also

7130
06:02:50,948 --> 06:02:49,280
helps them to get in and out of the

7131
06:02:53,110 --> 06:02:50,958
capsule it's a little trickier whenever

7132
06:02:55,110 --> 06:02:53,120
the seats are in the up position or when

7133
06:02:58,230 --> 06:02:55,120
they're when they're reclined facing

7134
06:03:00,070 --> 06:02:58,240
upward toward the top of the capsule as

7135
06:03:02,070 --> 06:03:00,080
for comfort level i've heard that they

7136
06:03:04,948 --> 06:03:02,080
have found it pretty comfortable

7137
06:03:07,430 --> 06:03:04,958
the seats are actually custom fitted for

7138
06:03:09,510 --> 06:03:07,440
each astronaut uh destined to be flying

7139
06:03:11,430 --> 06:03:09,520
in it so whenever a crew member is

7140
06:03:14,628 --> 06:03:11,440
assigned to a mission they will also be

7141
06:03:18,150 --> 06:03:14,638
assigned a seat specifically so there

7142
06:03:20,310 --> 06:03:18,160
will be no uh mid-flight fire drills

7143
06:03:21,990 --> 06:03:20,320
where everyone is switching seats

7144
06:03:24,548 --> 06:03:22,000
everyone has a designated seat they're

7145
06:03:27,270 --> 06:03:24,558
essentially small medium and large

7146
06:03:29,830 --> 06:03:27,280
and the arm rests are also customizable

7147
06:03:31,750 --> 06:03:29,840
depending on how long the crew member's

7148
06:03:34,470 --> 06:03:31,760
forearm is so

7149
06:03:36,788 --> 06:03:34,480
we have taken many steps with the

7150
06:03:38,390 --> 06:03:36,798
comfort in mind as well as style you've

7151
06:03:40,788 --> 06:03:38,400
seen those spacesuits they look pretty

7152
06:03:43,270 --> 06:03:40,798
good in my opinion but those spacesuits

7153
06:03:44,948 --> 06:03:43,280
are also similarly custom fitted for

7154
06:03:47,110 --> 06:03:44,958
each individual crew member so with the

7155
06:03:49,510 --> 06:03:47,120
combination of the custom fit of the

7156
06:03:50,470 --> 06:03:49,520
suit as well as the custom fit of the

7157
06:03:52,470 --> 06:03:50,480
seats

7158
06:03:54,868 --> 06:03:52,480
we have aimed to make it as comfortable

7159
06:03:56,708 --> 06:03:54,878
as possible uh in the event of you know

7160
06:03:58,788 --> 06:03:56,718
some sort of situation where we need to

7161
06:04:01,430 --> 06:03:58,798
wave off an activity uh you know for up

7162
06:04:03,590 --> 06:04:01,440
to 48 hours that's a long time to be in

7163
06:04:05,750 --> 06:04:03,600
a confined space even if you are highly

7164
06:04:07,270 --> 06:04:05,760
trained like these guys uh so yeah

7165
06:04:09,110 --> 06:04:07,280
making sure that they are as comfortable

7166
06:04:11,030 --> 06:04:09,120
as possible while inside the cabin was

7167
06:04:12,628 --> 06:04:11,040
certainly high priority

7168
06:04:13,670 --> 06:04:12,638
all right our next question comes from

7169
06:04:15,750 --> 06:04:13,680
richard

7170
06:04:17,270 --> 06:04:15,760
this one deals with kind of hygiene on

7171
06:04:18,708 --> 06:04:17,280
the space station just curious how the

7172
06:04:21,110 --> 06:04:18,718
astronauts that have been on station a

7173
06:04:22,868 --> 06:04:21,120
while how do they stay so clean cut i

7174
06:04:24,788 --> 06:04:22,878
know there's not a barber on board did

7175
06:04:26,948 --> 06:04:24,798
they cut their own hair it just looks

7176
06:04:28,150 --> 06:04:26,958
clean cut do they shower do laundry how

7177
06:04:30,470 --> 06:04:28,160
do they do it

7178
06:04:31,830 --> 06:04:30,480
they do have to cut their own hair

7179
06:04:34,230 --> 06:04:31,840
um and

7180
06:04:35,910 --> 06:04:34,240
uh even the current commander chris

7181
06:04:38,230 --> 06:04:35,920
cassidy who's still on board famously

7182
06:04:40,470 --> 06:04:38,240
shaved his head once as his fellow

7183
06:04:43,270 --> 06:04:40,480
crewmate luca parmitano was about to

7184
06:04:46,628 --> 06:04:43,280
arrive on space station just so he had

7185
06:04:49,190 --> 06:04:46,638
some some bald company

7186
06:04:50,708 --> 06:04:49,200
but they do have trimmers on board the

7187
06:04:52,708 --> 06:04:50,718
international space station that have a

7188
06:04:55,110 --> 06:04:52,718
vacuum attached to them so they're not

7189
06:04:56,548 --> 06:04:55,120
just getting hair just all throughout

7190
06:04:58,150 --> 06:04:56,558
the cabin as

7191
06:05:00,070 --> 06:04:58,160
like everything else hair would just

7192
06:05:02,150 --> 06:05:00,080
tend to float around and get caught in

7193
06:05:03,590 --> 06:05:02,160
the drafts of the air circulation on

7194
06:05:05,430 --> 06:05:03,600
board so they use

7195
06:05:07,590 --> 06:05:05,440
basically vacuum cutters

7196
06:05:08,868 --> 06:05:07,600
in order to give themselves haircuts so

7197
06:05:11,510 --> 06:05:08,878
that's how they're able to do it no

7198
06:05:15,110 --> 06:05:11,520
professional stylist up there

7199
06:05:16,708 --> 06:05:15,120
but they're able to to make do and

7200
06:05:19,270 --> 06:05:16,718
a little bit of shaggy

7201
06:05:23,350 --> 06:05:19,280
quick time check here as we just passed

7202
06:05:25,990 --> 06:05:23,360
10 30 it's now 10 32 here in california

7203
06:05:27,750 --> 06:05:26,000
we are less than 20 minutes away from

7204
06:05:30,708 --> 06:05:27,760
our first event

7205
06:05:32,470 --> 06:05:30,718
here on our list as bob and doug begin

7206
06:05:34,708 --> 06:05:32,480
to check off continue to check off the

7207
06:05:36,868 --> 06:05:34,718
boxes of their return home that first

7208
06:05:39,670 --> 06:05:36,878
event is claw separation that's

7209
06:05:41,110 --> 06:05:39,680
essentially the initiation of trunk

7210
06:05:43,190 --> 06:05:41,120
jettison

7211
06:05:44,390 --> 06:05:43,200
all of that means that we will need to

7212
06:05:46,708 --> 06:05:44,400
unlatch

7213
06:05:48,788 --> 06:05:46,718
the claw from the trunk

7214
06:05:50,868 --> 06:05:48,798
that is the mechanism that holds and

7215
06:05:52,390 --> 06:05:50,878
connects the trunk to the capsule

7216
06:05:55,110 --> 06:05:52,400
delivers fluid

7217
06:05:56,310 --> 06:05:55,120
telemetry power all that good stuff we

7218
06:05:58,390 --> 06:05:56,320
need to

7219
06:06:01,030 --> 06:05:58,400
expose the trunk in order for the

7220
06:06:02,310 --> 06:06:01,040
capsule to deorbit so we will jettison

7221
06:06:03,990 --> 06:06:02,320
the trunk

7222
06:06:06,230 --> 06:06:04,000
and then we will begin

7223
06:06:09,270 --> 06:06:06,240
a deorbit burn a couple minutes later

7224
06:06:12,670 --> 06:06:09,280
that deorbit burn is slated to begin

7225
06:06:16,230 --> 06:06:12,680
at 10 56 a.m pacific

7226
06:06:18,470 --> 06:06:16,240
1856 universal coordinated time so in

7227
06:06:32,788 --> 06:06:18,480
just 20 just under 23 minutes we're

7228
06:06:36,390 --> 06:06:34,310
once again if you're just joining us

7229
06:06:38,948 --> 06:06:36,400
we've got some live views inside the

7230
06:06:41,590 --> 06:06:38,958
dragon endeavor capsule bob and doug

7231
06:06:43,590 --> 06:06:41,600
they're in their seats as they are

7232
06:06:46,150 --> 06:06:43,600
making final preparations

7233
06:06:48,230 --> 06:06:46,160
and doing final reviews as we

7234
06:06:49,270 --> 06:06:48,240
get ready to initiate the deorbit

7235
06:06:50,948 --> 06:06:49,280
sequence

7236
06:06:53,110 --> 06:06:50,958
closest to the camera there is nasa

7237
06:06:55,190 --> 06:06:53,120
astronaut doug hurley and further away

7238
06:06:56,948 --> 06:06:55,200
from the camera is nasa astronaut bob

7239
06:06:58,150 --> 06:06:56,958
benkin

7240
06:06:59,470 --> 06:06:58,160
these are

7241
06:07:02,548 --> 06:06:59,480
two

7242
06:07:04,390 --> 06:07:02,558
incredibly incredible incredibly

7243
06:07:06,470 --> 06:07:04,400
wonderful humans

7244
06:07:08,868 --> 06:07:06,480
we affectionately call them our space

7245
06:07:11,110 --> 06:07:08,878
dads here at spacex

7246
06:07:13,670 --> 06:07:11,120
it's been such an honor to be able to

7247
06:07:15,990 --> 06:07:13,680
fly them of course doug hurley was

7248
06:07:19,350 --> 06:07:16,000
actually the pilot of the final space

7249
06:07:22,310 --> 06:07:19,360
shuttle mission sts sts-135

7250
06:07:23,910 --> 06:07:22,320
back in 2011 and

7251
06:07:26,548 --> 06:07:23,920
honestly when i heard that he was

7252
06:07:27,430 --> 06:07:26,558
assigned to this mission

7253
06:07:53,670 --> 06:07:27,440
i

7254
06:07:57,990 --> 06:07:55,670
well we know that they're ready

7255
06:07:59,670 --> 06:07:58,000
they've done all of their suit checkouts

7256
06:08:01,750 --> 06:07:59,680
everything to get themselves to this

7257
06:08:04,548 --> 06:08:01,760
point

7258
06:08:06,948 --> 06:08:04,558
and once we begin these events they're

7259
06:08:09,750 --> 06:08:06,958
going to keep a very close eye as again

7260
06:08:11,910 --> 06:08:09,760
crew is always in the loop to step in

7261
06:08:12,788 --> 06:08:11,920
but dragon going to be executing all of

7262
06:08:14,470 --> 06:08:12,798
these

7263
06:08:16,310 --> 06:08:14,480
different maneuvers and separation

7264
06:08:19,430 --> 06:08:16,320
events automatically

7265
06:08:21,830 --> 06:08:19,440
via a pre-programmed timeline

7266
06:08:23,830 --> 06:08:21,840
we're continuing to count down we'll

7267
06:08:26,708 --> 06:08:23,840
have our first maneuver in a little

7268
06:08:29,430 --> 06:08:26,718
under 13 minutes we're a little over 15

7269
06:08:31,910 --> 06:08:29,440
minutes from the claw separation

7270
06:08:33,190 --> 06:08:31,920
that claw connecting the service module

7271
06:08:35,350 --> 06:08:33,200
to the

7272
06:08:36,868 --> 06:08:35,360
the dragon capsule itself a series of

7273
06:08:39,830 --> 06:08:36,878
quick disconnects

7274
06:08:43,270 --> 06:08:39,840
will retract cutting off any of the

7275
06:08:45,350 --> 06:08:43,280
fluid and data paths between the two

7276
06:08:47,350 --> 06:08:45,360
and then shortly after that

7277
06:08:48,868 --> 06:08:47,360
just a few seconds later the trunk will

7278
06:08:52,070 --> 06:08:48,878
separate

7279
06:08:54,830 --> 06:08:52,080
and then we will be just less than five

7280
06:08:58,548 --> 06:08:54,840
minutes away from that deorbit

7281
06:09:10,708 --> 06:08:58,558
burn again deorbit burn expected to last

7282
06:09:14,868 --> 06:09:12,708
now of course during re-entry bob and

7283
06:09:17,030 --> 06:09:14,878
doug will be experiencing a couple of

7284
06:09:20,548 --> 06:09:17,040
g's we're anticipating them to

7285
06:09:22,230 --> 06:09:20,558
to feel about four g's during re-entry

7286
06:09:24,150 --> 06:09:22,240
this will make it a little difficult for

7287
06:09:25,430 --> 06:09:24,160
them to move their arms around not

7288
06:09:26,868 --> 06:09:25,440
impossible

7289
06:09:29,350 --> 06:09:26,878
but essentially what they're doing right

7290
06:09:33,030 --> 06:09:29,360
now is reviewing

7291
06:09:35,430 --> 06:09:33,040
all of the event details for splashdown

7292
06:09:38,708 --> 06:09:35,440
making sure that they i've said this

7293
06:09:41,030 --> 06:09:38,718
before they have rehearsed this both uh

7294
06:09:42,788 --> 06:09:41,040
via seek they've rehearsed the sequence

7295
06:09:45,270 --> 06:09:42,798
of events in person with the recovery

7296
06:09:46,788 --> 06:09:45,280
team as well as through simulations here

7297
06:09:48,708 --> 06:09:46,798
at mission control

7298
06:09:51,510 --> 06:09:48,718
or at spacex headquarters in hawthorne

7299
06:09:54,390 --> 06:09:51,520
california so at this point uh because

7300
06:09:55,910 --> 06:09:54,400
it will be difficult for them to maybe

7301
06:09:57,910 --> 06:09:55,920
flip through to the exact part of the

7302
06:10:00,628 --> 06:09:57,920
procedure they might want to review

7303
06:10:01,910 --> 06:10:00,638
during the actual re-entry event itself

7304
06:10:06,230 --> 06:10:01,920
they are

7305
06:10:09,510 --> 06:10:06,240
preparation for that splashdown or for

7306
06:10:13,110 --> 06:10:11,190
we've got another twitter question this

7307
06:10:14,470 --> 06:10:13,120
one from one from laura mountain this

7308
06:10:16,628 --> 06:10:14,480
one's pretty cool

7309
06:10:18,470 --> 06:10:16,638
is it quiet in the dragon or does it

7310
06:10:21,910 --> 06:10:18,480
sound like an airplane

7311
06:10:23,510 --> 06:10:21,920
at least not right now as they're still

7312
06:10:25,990 --> 06:10:23,520
flying through the vacuum of space

7313
06:10:27,750 --> 06:10:26,000
there's there's none of that rushing air

7314
06:10:28,868 --> 06:10:27,760
they'll get some of that

7315
06:10:30,150 --> 06:10:28,878
once they're

7316
06:10:32,070 --> 06:10:30,160
further down

7317
06:10:34,390 --> 06:10:32,080
during their descent

7318
06:10:36,948 --> 06:10:34,400
and then they're also able to hear when

7319
06:10:38,230 --> 06:10:36,958
the draco thrusters fire

7320
06:10:41,190 --> 06:10:38,240
and one of the really cool things

7321
06:10:42,948 --> 06:10:41,200
they've done to train the crew is spacex

7322
06:10:45,270 --> 06:10:42,958
had a number of microphones placed

7323
06:10:46,788 --> 06:10:45,280
throughout the cabin during that demo on

7324
06:10:48,390 --> 06:10:46,798
flight last year

7325
06:10:50,548 --> 06:10:48,400
and they were able to record what it

7326
06:10:52,628 --> 06:10:50,558
sounded like inside

7327
06:10:53,910 --> 06:10:52,638
through all of the major uh all of the

7328
06:10:55,670 --> 06:10:53,920
major burns

7329
06:10:59,190 --> 06:10:55,680
the launch the descent landing

7330
06:11:01,750 --> 06:10:59,200
everything and in the trainer upstairs

7331
06:11:03,910 --> 06:11:01,760
here at hawthorne at spacex headquarters

7332
06:11:06,150 --> 06:11:03,920
they have speakers set up where as

7333
06:11:07,590 --> 06:11:06,160
they're doing simulations or practice

7334
06:11:09,750 --> 06:11:07,600
runs of the different phases of the

7335
06:11:11,830 --> 06:11:09,760
mission they're able to hear what it

7336
06:11:13,670 --> 06:11:11,840
should sound like inside dragon as

7337
06:11:15,350 --> 06:11:13,680
they're going through that so

7338
06:11:16,788 --> 06:11:15,360
i know that's one thing bob pointed out

7339
06:11:17,510 --> 06:11:16,798
is one of the things they're looking for

7340
06:11:23,750 --> 06:11:17,520
is

7341
06:11:24,948 --> 06:11:23,760
light i'm supposed to see all of those

7342
06:11:27,190 --> 06:11:24,958
different things

7343
06:11:53,750 --> 06:11:27,200
that for them is like reflex by the time

7344
06:11:58,548 --> 06:11:57,030
all right well at this moment we are

7345
06:12:00,628 --> 06:11:58,558
less than 10 minutes away from this

7346
06:12:02,470 --> 06:12:00,638
sequence starting we are just about nine

7347
06:12:04,948 --> 06:12:02,480
minutes away in fact

7348
06:12:06,948 --> 06:12:04,958
and first we'll see that

7349
06:12:09,190 --> 06:12:06,958
uh maneuver

7350
06:12:10,788 --> 06:12:09,200
where we'll get into the proper attitude

7351
06:12:12,310 --> 06:12:10,798
or point dragon really in the right

7352
06:12:14,390 --> 06:12:12,320
direction for the claw and trunk

7353
06:12:16,948 --> 06:12:14,400
separation we're essentially going to do

7354
06:12:18,070 --> 06:12:16,958
a 90 degree yaw maneuver turn dragon

7355
06:12:19,030 --> 06:12:18,080
sideways

7356
06:12:21,350 --> 06:12:19,040
to

7357
06:12:22,548 --> 06:12:21,360
make sure the trunk goes out

7358
06:12:24,470 --> 06:12:22,558
and away

7359
06:12:26,708 --> 06:12:24,480
not coming out

7360
06:12:27,750 --> 06:12:26,718
in front of or behind the capsule

7361
06:12:29,270 --> 06:12:27,760
essentially

7362
06:12:31,350 --> 06:12:29,280
re-entering the atmosphere with the

7363
06:12:32,948 --> 06:12:31,360
capsule we're going to avoid that

7364
06:12:34,868 --> 06:12:32,958
and then dragon will position itself for

7365
06:12:37,830 --> 06:12:34,878
the d-orbit burn it's going to point

7366
06:12:39,350 --> 06:12:37,840
those forward bulkhead thrusters

7367
06:12:41,350 --> 06:12:39,360
into the direction that it's currently

7368
06:12:43,350 --> 06:12:41,360
traveling this is called a retrograde

7369
06:12:45,510 --> 06:12:43,360
maneuver and this is done

7370
06:12:47,590 --> 06:12:45,520
specifically to

7371
06:12:51,030 --> 06:12:47,600
we're going to slow the capsule down but

7372
06:12:54,070 --> 06:12:51,040
more than anything we're changing the

7373
06:12:55,830 --> 06:12:54,080
the perigee or the lowest point of the

7374
06:12:57,350 --> 06:12:55,840
capsule's orbit again

7375
06:12:58,868 --> 06:12:57,360
essentially putting it up on an

7376
06:13:00,390 --> 06:12:58,878
intersection point

7377
06:13:15,110 --> 06:13:00,400
with that spot in the gulf where we're

7378
06:13:15,120 --> 06:13:18,470
eight minutes kate

7379
06:13:18,480 --> 06:16:00,150
we are getting close

7380
06:16:00,160 --> 06:16:08,070
try again spacex for the orbit sequence

7381
06:16:10,470 --> 06:16:08,830
go

7382
06:16:12,788 --> 06:16:10,480
ahead

7383
06:16:14,868 --> 06:16:12,798
all right doug we are five minutes out

7384
06:16:17,350 --> 06:16:14,878
from the orbit sequence start in

7385
06:16:19,190 --> 06:16:17,360
addition i just wanted to inform you we

7386
06:16:21,110 --> 06:16:19,200
are expecting some ratty calm during

7387
06:16:28,150 --> 06:16:21,120
claw and trunk set due to vehicle

7388
06:16:36,390 --> 06:16:32,948
okay copy we see 4 45 left for the uh

7389
06:16:39,190 --> 06:16:36,400
slew and then randy comes during the

7390
06:17:07,110 --> 06:16:39,200
clock

7391
06:17:11,430 --> 06:17:09,750
okay we are almost four minutes away

7392
06:17:13,270 --> 06:17:11,440
from this starting yeah we just heard

7393
06:17:16,230 --> 06:17:13,280
the call out there confirmation from

7394
06:17:19,110 --> 06:17:16,240
spacex core down here at mission control

7395
06:17:20,788 --> 06:17:19,120
to crew dragon that we now under five

7396
06:17:23,510 --> 06:17:20,798
but at the time of the call five minutes

7397
06:17:25,590 --> 06:17:23,520
away from deorbit sequence start

7398
06:17:28,390 --> 06:17:25,600
so like we've been mentioning before

7399
06:17:31,030 --> 06:17:28,400
that the orbit sequence will involve

7400
06:17:33,030 --> 06:17:31,040
separating from the trunk and performing

7401
06:17:35,670 --> 06:17:33,040
the deorbit burn

7402
06:17:37,430 --> 06:17:35,680
as you may have noticed on your the

7403
06:17:39,510 --> 06:17:37,440
ground tracking map that we've been

7404
06:17:42,310 --> 06:17:39,520
showing you before bob and doug were in

7405
06:17:44,150 --> 06:17:42,320
their last orbit around earth

7406
06:17:46,150 --> 06:17:44,160
i i can't remember what the number was

7407
06:17:48,150 --> 06:17:46,160
that you you quoted earlier dan but they

7408
06:17:50,948 --> 06:17:48,160
have done thousands of orbits around

7409
06:17:54,470 --> 06:17:50,958
earth during their two-month uh duration

7410
06:17:56,788 --> 06:17:54,480
on station so it is really exciting that

7411
06:17:59,350 --> 06:17:56,798
the line that we see on that trajectory

7412
06:18:01,350 --> 06:17:59,360
map uh is no longer

7413
06:18:02,948 --> 06:18:01,360
you know fully around it they're coming

7414
06:18:04,470 --> 06:18:02,958
home we're not we're not seeing two

7415
06:18:06,070 --> 06:18:04,480
lines showing what their next orbit is

7416
06:18:08,948 --> 06:18:06,080
going to be they are on their final

7417
06:18:11,110 --> 06:18:08,958
orbit of planet earth um and this is

7418
06:18:13,430 --> 06:18:11,120
their 1024th

7419
06:18:15,750 --> 06:18:13,440
orbit around our planet since they

7420
06:18:17,990 --> 06:18:15,760
launched back in may

7421
06:18:19,990 --> 06:18:18,000
of earlier this year so

7422
06:18:21,910 --> 06:18:20,000
we're counting down we're under three

7423
06:18:24,150 --> 06:18:21,920
minutes away from that first maneuver

7424
06:18:26,150 --> 06:18:24,160
and that's going to be a slew as you

7425
06:18:27,430 --> 06:18:26,160
heard doug radio down

7426
06:18:28,868 --> 06:18:27,440
and that's essentially we're going to

7427
06:18:31,270 --> 06:18:28,878
change the attitude we're going to use

7428
06:18:34,150 --> 06:18:31,280
those draco thrusters to essentially

7429
06:18:35,750 --> 06:18:34,160
spin dragon about 90 degrees to the side

7430
06:18:37,430 --> 06:18:35,760
so we can

7431
06:18:39,590 --> 06:18:37,440
jettison that trunk

7432
06:18:41,510 --> 06:18:39,600
and that'll be done in two stages we'll

7433
06:18:43,670 --> 06:18:41,520
do the claw separation and then the

7434
06:18:47,270 --> 06:18:43,680
trunk separation

7435
06:18:48,548 --> 06:18:47,280
two minutes 32 seconds and counting this

7436
06:18:51,270 --> 06:18:48,558
is where things

7437
06:18:53,510 --> 06:18:51,280
really pick up this is where we really

7438
06:18:55,750 --> 06:18:53,520
commit to coming home and this is where

7439
06:18:57,830 --> 06:18:55,760
we're in kind of the final stages of bob

7440
06:18:59,670 --> 06:18:57,840
and doug's trip in outer space

7441
06:19:01,910 --> 06:18:59,680
pretty soon we'll be seeing them in the

7442
06:19:03,430 --> 06:19:01,920
gulf of mexico yeah well they are

7443
06:19:05,670 --> 06:19:03,440
staying comfortable and continuing to

7444
06:19:06,708 --> 06:19:05,680
monitor data and telemetry in the

7445
06:19:08,948 --> 06:19:06,718
vehicle

7446
06:19:11,190 --> 06:19:08,958
dragon is actually doing a couple of

7447
06:19:12,868 --> 06:19:11,200
things itself to prepare for this

7448
06:19:14,150 --> 06:19:12,878
deorbit sequence

7449
06:19:15,670 --> 06:19:14,160
again that's doing these things

7450
06:19:17,350 --> 06:19:15,680
autonomously

7451
06:19:19,670 --> 06:19:17,360
it's isolating the thermal control

7452
06:19:22,150 --> 06:19:19,680
system loops from the radiator this is

7453
06:19:23,590 --> 06:19:22,160
the system that will help keep bob and

7454
06:19:24,788 --> 06:19:23,600
doug cool

7455
06:19:26,390 --> 06:19:24,798
while they are re-entering the

7456
06:19:28,868 --> 06:19:26,400
atmosphere like we've said before the

7457
06:19:30,390 --> 06:19:28,878
external temperature will reach 3500

7458
06:19:32,548 --> 06:19:30,400
degrees fahrenheit

7459
06:19:34,948 --> 06:19:32,558
and that thermal control system

7460
06:19:37,110 --> 06:19:34,958
is what helps keep them cool

7461
06:19:39,670 --> 06:19:37,120
during that time also dragon is

7462
06:19:42,468 --> 06:19:39,680
initiating uh the separation of the claw

7463
06:19:44,310 --> 06:19:42,478
mechanism which will terminate the data

7464
06:19:46,150 --> 06:19:44,320
the power and the fluid connect and the

7465
06:19:48,310 --> 06:19:46,160
fluid connections between the capsule

7466
06:19:51,670 --> 06:19:48,320
and the trunk so right now the vehicle

7467
06:19:54,468 --> 06:19:51,680
is preparing to execute that and we are

7468
06:19:55,910 --> 06:19:54,478
anticipating execution of claw

7469
06:19:59,990 --> 06:19:55,920
separation

7470
06:20:02,548 --> 06:20:00,000
in three minutes and 35 seconds so

7471
06:20:04,948 --> 06:20:02,558
you know we've been here for

7472
06:20:07,590 --> 06:20:04,958
10 hours i think at this point the

7473
06:20:10,150 --> 06:20:07,600
webcast as a whole has been going on for

7474
06:20:11,990 --> 06:20:10,160
almost a little bit less than 24 hours

7475
06:20:14,548 --> 06:20:12,000
so you know we're in the final moments

7476
06:20:16,868 --> 06:20:14,558
here as dragon is beginning it's it's

7477
06:20:19,030 --> 06:20:16,878
journey home uh to bring bob and doug

7478
06:20:20,548 --> 06:20:19,040
back to earth yeah this is this is the

7479
06:20:22,868 --> 06:20:20,558
moment that dragon

7480
06:20:24,788 --> 06:20:22,878
is in the position to start coming home

7481
06:20:26,548 --> 06:20:24,798
uh the recovery team's already on

7482
06:20:28,708 --> 06:20:26,558
station they have been for a while out

7483
06:20:30,548 --> 06:20:28,718
there off the coast of pensacola we are

7484
06:20:32,948 --> 06:20:30,558
less than a minute from starting all of

7485
06:20:35,030 --> 06:20:32,958
these carefully choreographed sequences

7486
06:20:37,110 --> 06:20:35,040
to essentially split dragon in half get

7487
06:20:38,788 --> 06:20:37,120
rid of that trunk so we have the capsule

7488
06:20:40,468 --> 06:20:38,798
i'll point the heat shield back down

7489
06:20:41,990 --> 06:20:40,478
towards earth following that deorbit

7490
06:20:43,830 --> 06:20:42,000
burn

7491
06:20:46,150 --> 06:20:43,840
and then we bring them home we are just

7492
06:20:48,708 --> 06:20:46,160
about 30 seconds away now

7493
06:20:50,788 --> 06:20:48,718
from maneuvering dragon to get ready to

7494
06:20:52,868 --> 06:20:50,798
get rid of that claw first and then that

7495
06:20:54,868 --> 06:20:52,878
trunk separation there will be about a

7496
06:20:57,110 --> 06:20:54,878
35 second difference

7497
06:20:59,350 --> 06:20:57,120
or 35 second jump from separating the

7498
06:21:00,788 --> 06:20:59,360
claw to separating the trunk and we'll

7499
06:21:02,628 --> 06:21:00,798
keep our eyes on the ground track for

7500
06:21:04,628 --> 06:21:02,638
you and make sure we get kind of exact

7501
06:21:06,150 --> 06:21:04,638
locations of when these separation

7502
06:21:07,590 --> 06:21:06,160
events are occurring

7503
06:21:09,590 --> 06:21:07,600
we're we're looking for both the call on

7504
06:21:11,430 --> 06:21:09,600
the trunk to separate cleanly and then

7505
06:21:13,910 --> 06:21:11,440
it'll be less than five minutes until we

7506
06:21:14,708 --> 06:21:13,920
do the deorbit burn yeah and after that

7507
06:21:18,788 --> 06:21:14,718
it'll

7508
06:21:22,310 --> 06:21:18,798
drag in spacex deorbit sequence start

7509
06:21:26,788 --> 06:21:23,750
great news

7510
06:21:32,310 --> 06:21:28,788
all right so the draco thrusters on

7511
06:21:34,468 --> 06:21:32,320
dragon starting to fire

7512
06:21:38,310 --> 06:21:34,478
now moving its way over to the trunk

7513
06:22:11,910 --> 06:21:40,070
we should be about two minutes away from

7514
06:22:16,788 --> 06:22:14,070
for those of you that are just tuning in

7515
06:22:18,708 --> 06:22:16,798
you are just in time

7516
06:22:21,110 --> 06:22:18,718
at this point in the mission we are now

7517
06:22:24,070 --> 06:22:21,120
beginning to execute the final steps of

7518
06:22:26,788 --> 06:22:24,080
dragon endeavor's return to earth

7519
06:22:28,868 --> 06:22:26,798
right now we are performing the claw

7520
06:22:31,030 --> 06:22:28,878
separation slew which basically means

7521
06:22:32,230 --> 06:22:31,040
dragon is maneuvering itself into

7522
06:22:34,708 --> 06:22:32,240
position

7523
06:22:36,708 --> 06:22:34,718
into the proper attitude in order to

7524
06:22:39,110 --> 06:22:36,718
separate the dragon trunk

7525
06:22:41,590 --> 06:22:39,120
and that will be initiated first

7526
06:22:44,070 --> 06:22:41,600
by separation of the claw the claw is

7527
06:22:47,110 --> 06:22:44,080
the mechanism that attaches

7528
06:22:49,190 --> 06:22:47,120
the trunk and the

7529
06:22:50,788 --> 06:22:49,200
excuse me and the capsule together the

7530
06:22:54,628 --> 06:22:50,798
claw is what delivers power and

7531
06:22:56,788 --> 06:22:54,638
telemetry and fluids and we need to

7532
06:22:58,788 --> 06:22:56,798
expose the heat shield

7533
06:23:00,708 --> 06:22:58,798
right now the trunk is blocking that so

7534
06:23:03,830 --> 06:23:00,718
we will jettison the trunk

7535
06:23:05,750 --> 06:23:03,840
and we will

7536
06:23:07,430 --> 06:23:05,760
then have

7537
06:23:10,708 --> 06:23:07,440
allow us to maneuver into the proper

7538
06:23:12,230 --> 06:23:10,718
attitude to perform the deorbit burn

7539
06:23:14,708 --> 06:23:12,240
which dragon has performed a number of

7540
06:23:16,468 --> 06:23:14,718
burns so far overnight

7541
06:23:18,310 --> 06:23:16,478
and early this morning

7542
06:23:21,270 --> 06:23:18,320
and this will be the final burn that the

7543
06:23:23,190 --> 06:23:21,280
vehicle has to perform for this mission

7544
06:23:26,070 --> 06:23:23,200
and we just heard confirmation dragons

7545
06:23:41,590 --> 06:23:26,080
in the trunk separation attitude we are

7546
06:23:41,600 --> 06:23:46,310
and we just heard confirmation

7547
06:23:46,320 --> 06:23:53,190
confirmation of closet

7548
06:23:57,110 --> 06:23:55,030
and with the claw separated we're now

7549
06:24:14,070 --> 06:23:57,120
standing by for the trunk separation in

7550
06:24:14,080 --> 06:24:35,110
10 seconds till trunk separation

7551
06:24:39,670 --> 06:24:37,110
and we just heard confirmation of trunks

7552
06:24:44,468 --> 06:24:39,680
separation

7553
06:24:46,390 --> 06:24:44,478
pacific

7554
06:24:48,868 --> 06:24:46,400
with dragon flying

7555
06:24:51,430 --> 06:24:48,878
over the indian ocean just off to the

7556
06:24:57,350 --> 06:24:51,440
west of australia dragon spacex we

7557
06:24:57,360 --> 06:25:03,030
oh yeah we felt it

7558
06:25:06,548 --> 06:25:04,548
all right

7559
06:25:08,310 --> 06:25:06,558
so the crew just got the call nominal

7560
06:25:09,990 --> 06:25:08,320
trunk separation that's exactly what we

7561
06:25:12,628 --> 06:25:10,000
were looking for next up is going to be

7562
06:25:14,628 --> 06:25:12,638
that deal that deorbit burn

7563
06:25:17,030 --> 06:25:14,638
again this is the longest burn of their

7564
06:25:18,708 --> 06:25:17,040
trip home this is the longest firing of

7565
06:25:20,788 --> 06:25:18,718
those thrusters in the last time we're

7566
06:25:22,070 --> 06:25:20,798
using those forward bulkhead thrusters

7567
06:25:23,750 --> 06:25:22,080
exactly

7568
06:25:25,510 --> 06:25:23,760
those forward bulkhead thrusters like

7569
06:25:28,390 --> 06:25:25,520
dan just said that's what we're using to

7570
06:25:30,150 --> 06:25:28,400
perform the deorbit burn once we

7571
06:25:32,390 --> 06:25:30,160
do that we will then be able that

7572
06:25:34,868 --> 06:25:32,400
deorgan will last for 11 and a half

7573
06:25:37,350 --> 06:25:34,878
minutes once that is completed we don't

7574
06:25:40,150 --> 06:25:37,360
need to use those thrusters anymore so

7575
06:25:49,510 --> 06:25:40,160
we will close and lock the nose cone in

7576
06:25:52,788 --> 06:25:51,030
so we're a little under three and a half

7577
06:25:53,590 --> 06:25:52,798
minutes from the start of the deorbit

7578
06:25:55,830 --> 06:25:53,600
burn

7579
06:25:58,868 --> 06:25:55,840
again our sequence of events has started

7580
06:25:59,990 --> 06:25:58,878
we're able to separate that claw at

7581
06:26:03,350 --> 06:26:00,000
10

7582
06:26:05,270 --> 06:26:03,360
51 a.m pacific

7583
06:26:08,310 --> 06:26:05,280
at 1751

7584
06:26:10,150 --> 06:26:08,320
gmt or universal time

7585
06:26:11,830 --> 06:26:10,160
and at 10 52 just a minute later the

7586
06:26:15,670 --> 06:26:11,840
trunk separating while dragon was flying

7587
06:26:18,390 --> 06:26:15,680
just off to the west of australia

7588
06:26:21,590 --> 06:26:18,400
so claw separated trunks separated next

7589
06:26:24,310 --> 06:26:21,600
up the orbit burn yeah right now

7590
06:26:26,628 --> 06:26:24,320
dragon is running exclusively on battery

7591
06:26:28,868 --> 06:26:26,638
power now that the trunk is separated

7592
06:26:30,628 --> 06:26:28,878
also right now

7593
06:26:33,670 --> 06:26:30,638
telemetry is looking really good for the

7594
06:26:36,150 --> 06:26:33,680
vehicle the nitrox system is primed for

7595
06:26:38,468 --> 06:26:36,160
cabin and suit cooling and the heat

7596
06:26:40,708 --> 06:26:38,478
shield is exposed and ready for atmos

7597
06:26:42,708 --> 06:26:40,718
atmospheric reentry

7598
06:26:45,190 --> 06:26:42,718
like i said before that nitrox system

7599
06:26:47,510 --> 06:26:45,200
which is essentially the air that we

7600
06:26:51,110 --> 06:26:47,520
breathe every day down here on earth

7601
06:26:52,628 --> 06:26:51,120
nitrogen oxygen combination mixture

7602
06:26:55,510 --> 06:26:52,638
it's the same stuff that they put in

7603
06:26:58,628 --> 06:26:55,520
your scuba tank if you are a scuba diver

7604
06:27:00,230 --> 06:26:58,638
the nitrox system is used to cool the

7605
06:27:02,948 --> 06:27:00,240
cabin and the suit

7606
06:27:04,708 --> 06:27:02,958
to keep the crew comfortable during the

7607
06:27:07,030 --> 06:27:04,718
reentry phase

7608
06:27:10,310 --> 06:27:07,040
they will actually have cold air flowing

7609
06:27:12,788 --> 06:27:10,320
through the their suits themselves as

7610
06:27:14,628 --> 06:27:12,798
well as through the cabin itself so a

7611
06:27:15,910 --> 06:27:14,638
two-pronged approach to maintaining a

7612
06:27:19,430 --> 06:27:15,920
comfortable

7613
06:27:22,310 --> 06:27:19,440
capsule

7614
06:27:25,350 --> 06:27:22,320
like we said the next event that we have

7615
06:27:27,190 --> 06:27:25,360
coming up will be the deorbit burn

7616
06:27:53,190 --> 06:27:27,200
which we're expecting that to commence

7617
06:27:58,150 --> 06:27:55,670
according to the ground tracking map

7618
06:27:59,830 --> 06:27:58,160
there dragon is approaching the

7619
06:28:01,270 --> 06:27:59,840
southwestern

7620
06:28:16,788 --> 06:28:01,280
coast of

7621
06:28:22,868 --> 06:28:18,390
excited

7622
06:28:26,230 --> 06:28:24,548
and again one more time this is this is

7623
06:28:29,510 --> 06:28:26,240
the long one this is

7624
06:28:31,110 --> 06:28:29,520
expected to last 11 minutes 22 seconds

7625
06:28:32,868 --> 06:28:31,120
this is that burn that

7626
06:28:34,628 --> 06:28:32,878
commits the dragon to re-enter in the

7627
06:28:36,390 --> 06:28:34,638
earth's atmosphere and you can get kind

7628
06:28:37,430 --> 06:28:36,400
of a sense of just how far they're going

7629
06:28:39,270 --> 06:28:37,440
to go

7630
06:28:41,350 --> 06:28:39,280
by the time they fire this burn they're

7631
06:28:44,070 --> 06:28:41,360
just going to be off to the southwest of

7632
06:28:45,590 --> 06:28:44,080
australia and this is going to realign

7633
06:28:47,830 --> 06:28:45,600
their orbit

7634
06:28:49,190 --> 06:28:47,840
to intersect with that point off the

7635
06:28:51,030 --> 06:28:49,200
coast of pensacola where they're going

7636
06:28:53,270 --> 06:28:51,040
to be splashing down

7637
06:28:56,628 --> 06:28:53,280
yeah this is the moment where dragon is

7638
06:28:58,868 --> 06:28:56,638
fully committed to the reentry point

7639
06:29:01,510 --> 06:28:58,878
again we are aiming for

7640
06:29:03,990 --> 06:29:01,520
just off the coast of pensacola florida

7641
06:29:06,070 --> 06:29:04,000
our recovery ship go navigator is ready

7642
06:29:09,350 --> 06:29:06,080
and waiting to begin the recovery

7643
06:29:11,590 --> 06:29:09,360
process right after splashdown occurs

7644
06:29:13,510 --> 06:29:11,600
once again uh if you're just joining us

7645
06:29:16,868 --> 06:29:13,520
we are now in the

7646
06:29:18,468 --> 06:29:16,878
final steps of the deorbit sequence

7647
06:29:20,548 --> 06:29:18,478
the do orbit burn

7648
06:29:21,750 --> 06:29:20,558
will be starting here in just a couple

7649
06:29:23,670 --> 06:29:21,760
of seconds

7650
06:29:25,590 --> 06:29:23,680
and we just heard confirmation deorbit

7651
06:29:26,708 --> 06:29:25,600
burn has begun

7652
06:29:30,868 --> 06:29:26,718
coming

7653
06:29:32,468 --> 06:29:30,878
at 10 56 a.m pacific again while the

7654
06:29:35,110 --> 06:29:32,478
dragon spacecraft just off the

7655
06:29:36,948 --> 06:29:35,120
southwestern coast of australia

7656
06:29:38,070 --> 06:29:36,958
so

7657
06:29:41,590 --> 06:29:38,080
here we go

7658
06:29:43,590 --> 06:29:41,600
11 more minutes to go i'm ready and i'm

7659
06:29:45,670 --> 06:29:43,600
sure it's safe to say that bob and doug

7660
06:29:47,830 --> 06:29:45,680
are ready they they've done a number of

7661
06:29:50,708 --> 06:29:47,840
interviews over the last few weeks while

7662
06:29:52,628 --> 06:29:50,718
they were on station and just the

7663
06:29:55,270 --> 06:29:52,638
excitement and the enthusiasm for the

7664
06:29:57,190 --> 06:29:55,280
mission is is palpable

7665
06:29:59,270 --> 06:29:57,200
just the opportunity to

7666
06:30:01,110 --> 06:29:59,280
be able to fly these two incredible

7667
06:30:04,230 --> 06:30:01,120
humans to the international space

7668
06:30:05,910 --> 06:30:04,240
station and back is such an honor and

7669
06:30:07,270 --> 06:30:05,920
we're just really excited to get our

7670
06:30:09,510 --> 06:30:07,280
space dads

7671
06:30:14,230 --> 06:30:09,520
home safely and back to their families

7672
06:30:19,670 --> 06:30:16,390
this deorbit burn that we are currently

7673
06:30:26,230 --> 06:30:19,680
in it will last 11 minutes and 22

7674
06:30:30,390 --> 06:30:28,310
already a little more than a minute 10

7675
06:30:33,270 --> 06:30:30,400
in counting so we have about 10 minutes

7676
06:30:35,270 --> 06:30:34,390
just heard a

7677
06:30:37,110 --> 06:30:35,280
call

7678
06:30:39,430 --> 06:30:37,120
the propulsion system performing

7679
06:30:45,830 --> 06:30:39,440
nominally that's the word we always want

7680
06:30:50,390 --> 06:30:47,990
just under 10 minutes to go left in this

7681
06:30:55,350 --> 06:30:53,030
and all within the last 10 minutes

7682
06:30:57,110 --> 06:30:55,360
again it seemed like we had slow

7683
06:30:58,628 --> 06:30:57,120
progress of events all morning and then

7684
06:31:00,868 --> 06:30:58,638
boom within the last 10 minutes we had a

7685
06:31:03,110 --> 06:31:00,878
couple of things happening uh dragon

7686
06:31:05,750 --> 06:31:03,120
maneuvered itself into the appropriate

7687
06:31:08,788 --> 06:31:05,760
position to jettison its trunk

7688
06:31:11,030 --> 06:31:08,798
and it did so successfully nominally and

7689
06:31:12,868 --> 06:31:11,040
then it initiated the deorbit burn just

7690
06:31:14,628 --> 06:31:12,878
a couple minutes ago

7691
06:31:17,190 --> 06:31:14,638
like i mentioned earlier this deorbit

7692
06:31:19,750 --> 06:31:17,200
burn is the last time those four forward

7693
06:31:22,150 --> 06:31:19,760
draco thrusters will fire forward kind

7694
06:31:24,150 --> 06:31:22,160
of meaning at the top of the capsule

7695
06:31:26,708 --> 06:31:24,160
dragon endeavor has not yet entered

7696
06:31:28,788 --> 06:31:26,718
earth's atmosphere but this deorbit burn

7697
06:31:30,468 --> 06:31:28,798
is what will line the vehicle up and put

7698
06:31:33,510 --> 06:31:30,478
it on its final trajectory to the

7699
06:31:34,390 --> 06:31:33,520
landing site in the gulf of mexico

7700
06:31:36,150 --> 06:31:34,400
right now

7701
06:31:38,548 --> 06:31:36,160
although we can't see it at the moment

7702
06:31:41,190 --> 06:31:38,558
bob and doug are using their screens to

7703
06:31:43,350 --> 06:31:41,200
keep tabs on the burn duration

7704
06:31:45,990 --> 06:31:43,360
draco fire excuse me draco thrust their

7705
06:31:49,030 --> 06:31:46,000
firings and trajectory details such as

7706
06:31:51,430 --> 06:31:49,040
entry angle capsule perigee and how much

7707
06:31:54,230 --> 06:31:51,440
distance is remaining until that deorbit

7708
06:31:56,708 --> 06:31:54,240
burn terminates so dragon is flying

7709
06:31:58,628 --> 06:31:56,718
itself so all they really have to do is

7710
06:32:25,030 --> 06:31:58,638
stay strapped in their seats and keep

7711
06:32:29,350 --> 06:32:27,110
so while this burn is completing again

7712
06:32:34,310 --> 06:32:29,360
we're just a few minutes into it it'll

7713
06:32:39,590 --> 06:32:36,628
uh we we have a couple more events

7714
06:32:41,430 --> 06:32:39,600
coming up afterward in

7715
06:32:44,390 --> 06:32:41,440
let me check my timeline here real quick

7716
06:32:46,150 --> 06:32:44,400
in 40 just under 44 minutes

7717
06:32:48,230 --> 06:32:46,160
we will have the initial parachute

7718
06:32:49,830 --> 06:32:48,240
deployment so

7719
06:32:51,670 --> 06:32:49,840
that is essentially when we will be

7720
06:32:54,390 --> 06:32:51,680
deploying the drogue parachutes the

7721
06:32:57,030 --> 06:32:54,400
small parachutes that are designed to

7722
06:32:59,030 --> 06:32:57,040
further slow down the capsule as as it

7723
06:33:00,468 --> 06:32:59,040
is re-entering the atmosphere as well as

7724
06:33:02,390 --> 06:33:00,478
stabilizing it

7725
06:33:05,030 --> 06:33:02,400
and then a minute after that we will

7726
06:33:08,510 --> 06:33:05,040
deploy the drogue parachutes and that is

7727
06:33:10,390 --> 06:33:08,520
targeted for 11 44 am pacific

7728
06:33:11,750 --> 06:33:10,400
1844

7729
06:33:13,190 --> 06:33:11,760
universal

7730
06:33:18,150 --> 06:33:13,200
and then just a couple minutes after

7731
06:33:22,468 --> 06:33:21,350
so again that's all in just under 45 44

7732
06:33:24,830 --> 06:33:22,478
minutes

7733
06:33:27,110 --> 06:33:24,840
right now we are performing the deorbit

7734
06:33:29,590 --> 06:33:27,120
burn we've got a little over seven

7735
06:33:31,590 --> 06:33:29,600
minutes left in this burn

7736
06:33:33,030 --> 06:33:31,600
and the only performance call we've

7737
06:33:34,708 --> 06:33:33,040
gotten so far is everything still

7738
06:33:36,468 --> 06:33:34,718
looking good with the propulsion system

7739
06:33:38,628 --> 06:33:36,478
on dragon

7740
06:33:40,390 --> 06:33:38,638
once this burn completes we will have

7741
06:33:42,788 --> 06:33:40,400
kind of a couple minutes

7742
06:33:45,190 --> 06:33:42,798
about three minutes to catch our breath

7743
06:33:46,948 --> 06:33:45,200
before things pick right back up and we

7744
06:33:49,350 --> 06:33:46,958
get the nose cone closed

7745
06:33:51,190 --> 06:33:49,360
and then there'll be a bit more of a gap

7746
06:33:52,868 --> 06:33:51,200
and at that point

7747
06:33:55,830 --> 06:33:52,878
they will maneuver

7748
06:33:59,270 --> 06:33:55,840
dragon to its entry attitude essentially

7749
06:34:01,270 --> 06:33:59,280
heat shield pointed down and into the

7750
06:34:03,110 --> 06:34:01,280
the line of velocity

7751
06:34:05,750 --> 06:34:03,120
and that heat shield protecting them

7752
06:34:07,750 --> 06:34:05,760
from the heat of reentry

7753
06:34:08,868 --> 06:34:07,760
temperatures getting up to about 3 500

7754
06:34:11,190 --> 06:34:08,878
degrees

7755
06:34:13,030 --> 06:34:11,200
on the dragon spacecraft but everything

7756
06:34:15,430 --> 06:34:13,040
looking good we're about five minutes

7757
06:34:17,190 --> 06:34:15,440
into this deorbit burn again it started

7758
06:34:19,110 --> 06:34:17,200
right at 10 56

7759
06:34:21,030 --> 06:34:19,120
a.m pacific time

7760
06:34:22,788 --> 06:34:21,040
1756

7761
06:34:25,190 --> 06:34:22,798
56 gmt

7762
06:34:26,150 --> 06:34:25,200
uh dragon was flying about 260 statute

7763
06:34:27,910 --> 06:34:26,160
miles

7764
06:34:54,708 --> 06:34:27,920
just off the southwestern coast of

7765
06:35:00,070 --> 06:34:57,350
so right now during this burn

7766
06:35:02,868 --> 06:35:01,590
we just heard a call that we're halfway

7767
06:35:04,628 --> 06:35:02,878
through the burn and everything is

7768
06:35:06,390 --> 06:35:04,638
looking great everything performing

7769
06:35:08,468 --> 06:35:06,400
nominally

7770
06:35:11,270 --> 06:35:08,478
during this burn right now bob and doug

7771
06:35:13,830 --> 06:35:11,280
are currently monitoring the deorbit

7772
06:35:16,948 --> 06:35:13,840
tool which like i said earlier captures

7773
06:35:19,590 --> 06:35:16,958
things like the perigee the re-entry

7774
06:35:22,468 --> 06:35:19,600
interface how much time excuse me how

7775
06:35:25,110 --> 06:35:22,478
many mile how much distance remains

7776
06:35:26,548 --> 06:35:25,120
before the burn itself

7777
06:35:27,910 --> 06:35:26,558
is terminated

7778
06:35:29,590 --> 06:35:27,920
they're also monitoring the burn

7779
06:35:32,468 --> 06:35:29,600
duration and

7780
06:35:34,390 --> 06:35:32,478
the firing of those draco thrusters

7781
06:35:36,948 --> 06:35:34,400
located there at the

7782
06:35:38,390 --> 06:35:36,958
on the forward bulkhead of the capsule

7783
06:35:40,070 --> 06:35:38,400
there on your screen you actually can

7784
06:35:40,948 --> 06:35:40,080
see what bob and doug are seeing right

7785
06:35:42,310 --> 06:35:40,958
now

7786
06:35:45,110 --> 06:35:42,320
that is

7787
06:35:47,270 --> 06:35:45,120
that tool on their screen so on the left

7788
06:35:50,150 --> 06:35:47,280
and the right of the center screen

7789
06:36:23,430 --> 06:35:50,160
that is the deorbit

7790
06:36:28,788 --> 06:36:25,510
just passed seven minutes into the burn

7791
06:36:30,230 --> 06:36:28,798
a little over four minutes remaining

7792
06:36:32,310 --> 06:36:30,240
everything's still looking good with

7793
06:36:34,150 --> 06:36:32,320
dragon chip endeavour's dior burn to

7794
06:36:37,030 --> 06:36:34,160
commit it to coming home

7795
06:36:39,190 --> 06:36:37,040
everything continuing to be on track

7796
06:36:40,788 --> 06:36:39,200
for our splashdown again our splashdown

7797
06:36:42,948 --> 06:36:40,798
time

7798
06:36:44,788 --> 06:36:42,958
right at 11 48

7799
06:36:47,750 --> 06:36:44,798
and 24 seconds

7800
06:36:49,590 --> 06:36:47,760
uh pacific was the calculated time uh

7801
06:36:52,708 --> 06:36:49,600
would

7802
06:36:56,708 --> 06:36:52,718
on either side

7803
06:36:58,070 --> 06:36:56,718
but that time is 1848 gmt or universal

7804
06:36:59,430 --> 06:36:58,080
but we're

7805
06:37:01,430 --> 06:36:59,440
we're already through several of the

7806
06:37:03,750 --> 06:37:01,440
really major steps to initiate this

7807
06:37:06,948 --> 06:37:03,760
re-entry the claw is separated the trunk

7808
06:37:08,948 --> 06:37:06,958
is gone the de-orbit burn has begun and

7809
06:37:10,788 --> 06:37:08,958
we're more than halfway through just a

7810
06:37:32,310 --> 06:37:10,798
little under three and a half minutes

7811
06:37:36,230 --> 06:37:34,150
there on your screen is a shot of our

7812
06:37:39,190 --> 06:37:36,240
mission control center here at spacex

7813
06:37:42,230 --> 06:37:39,200
headquarters in hawthorne california

7814
06:37:44,390 --> 06:37:42,240
where the dragon operators and

7815
06:37:47,350 --> 06:37:44,400
mission leaders are there monitoring

7816
06:37:49,190 --> 06:37:47,360
dragon's progress they continue to

7817
06:37:50,548 --> 06:37:49,200
watch the propulsion data and all the

7818
06:37:51,990 --> 06:37:50,558
gnc data

7819
06:38:05,510 --> 06:37:52,000
making sure that everything is looking

7820
06:38:10,390 --> 06:38:07,190
and we're just about two minutes 30

7821
06:38:12,468 --> 06:38:10,400
seconds until the end of this burn

7822
06:38:13,910 --> 06:38:12,478
we'll listen for the call out up to the

7823
06:38:15,990 --> 06:38:13,920
crew

7824
06:38:17,670 --> 06:38:16,000
on the performance of the burn and then

7825
06:38:19,350 --> 06:38:17,680
they'll start moving into the next steps

7826
06:38:21,990 --> 06:38:19,360
again we'll get about a three minute

7827
06:38:23,910 --> 06:38:22,000
breather before the next major milestone

7828
06:38:25,270 --> 06:38:23,920
comes up when we get ready to close the

7829
06:38:27,350 --> 06:38:25,280
nose cone

7830
06:38:29,430 --> 06:38:27,360
that protecting the docking ring

7831
06:38:31,190 --> 06:38:29,440
guidance navigation and control

7832
06:38:33,430 --> 06:38:31,200
sensors and also

7833
06:38:34,788 --> 06:38:33,440
these four forward bulkhead thrusters

7834
06:38:36,628 --> 06:38:34,798
that are currently performing the

7835
06:38:40,150 --> 06:38:36,638
deorbit burn

7836
06:38:43,030 --> 06:38:40,160
during the actual reentry process so

7837
06:38:50,868 --> 06:38:43,040
we are at just under two minutes

7838
06:38:55,910 --> 06:38:53,910
again dragon is committed to its

7839
06:38:59,750 --> 06:38:55,920
splashdown point

7840
06:39:04,468 --> 06:39:02,070
yeah we already have the recovery team

7841
06:39:08,070 --> 06:39:04,478
ready and on standby they've been there

7842
06:39:11,590 --> 06:39:09,910
here and we have about 90 seconds left

7843
06:39:13,510 --> 06:39:11,600
in the burn

7844
06:39:15,350 --> 06:39:13,520
weather looking great at the splashdown

7845
06:39:16,708 --> 06:39:15,360
site off pensacola

7846
06:39:18,868 --> 06:39:16,718
winds

7847
06:39:19,990 --> 06:39:18,878
just around two and a half miles per

7848
06:39:22,868 --> 06:39:20,000
hour

7849
06:39:24,788 --> 06:39:22,878
c being described as light glass by the

7850
06:39:27,350 --> 06:39:24,798
core here in hawthorne radioing up to

7851
06:39:30,390 --> 06:39:27,360
the crew ended up getting fantastic

7852
06:39:34,070 --> 06:39:30,400
weather for this first crude splashdown

7853
06:39:36,948 --> 06:39:34,080
of dragon we are one minute away from

7854
06:39:39,190 --> 06:39:36,958
the end of the orbit burn

7855
06:39:41,670 --> 06:39:39,200
again this burn is placing dragon on its

7856
06:39:44,548 --> 06:39:41,680
final trajectory to the landing site off

7857
06:39:46,628 --> 06:39:44,558
of the coast of pensacola florida that

7858
06:39:49,110 --> 06:39:46,638
is in the gulf of mexico

7859
06:39:50,868 --> 06:39:49,120
and our recovery vessel go navigator and

7860
06:39:52,788 --> 06:39:50,878
the recovery team

7861
06:39:54,390 --> 06:39:52,798
are ready and waiting

7862
06:40:01,670 --> 06:39:54,400
to see bob and doug come back through

7863
06:40:01,680 --> 06:40:06,230
like we said this burn uh journalists

7864
06:40:32,548 --> 06:40:08,150
atmosphere just yet

7865
06:40:32,558 --> 06:40:46,708
me

7866
06:40:51,830 --> 06:40:49,350
dragon spacex deorbit burn complete

7867
06:40:55,430 --> 06:40:51,840
performance nominal nose cone closure

7868
06:40:55,440 --> 06:41:13,590
by little birds

7869
06:41:13,600 --> 06:41:16,230
all right

7870
06:41:21,510 --> 06:41:18,150
the orbit burn complete we heard the

7871
06:41:22,548 --> 06:41:21,520
call nominal burn bob and doug are on

7872
06:41:25,110 --> 06:41:22,558
their way

7873
06:41:28,390 --> 06:41:25,120
back home this burn commits them to

7874
06:41:30,230 --> 06:41:28,400
re-entering the earth's atmosphere

7875
06:41:32,468 --> 06:41:30,240
all their all we have left now is to

7876
06:41:34,150 --> 06:41:32,478
wait that was really one of the last

7877
06:41:35,910 --> 06:41:34,160
major moments before they start

7878
06:41:37,830 --> 06:41:35,920
re-entering the earth's atmosphere we'll

7879
06:41:40,230 --> 06:41:37,840
have the nose cone closure coming up

7880
06:41:41,990 --> 06:41:40,240
next that should be coming in just a

7881
06:41:43,830 --> 06:41:42,000
couple of minutes as uh we had about a

7882
06:41:45,990 --> 06:41:43,840
three-minute span between the end of the

7883
06:41:48,310 --> 06:41:46,000
deal burn in that moment yeah the nose

7884
06:41:50,868 --> 06:41:48,320
cone is actually currently in the

7885
06:41:53,990 --> 06:41:50,878
closing process so it doesn't just snap

7886
06:41:56,310 --> 06:41:54,000
shut it does slowly close and

7887
06:41:58,468 --> 06:41:56,320
lock so right now that nose cone is in

7888
06:42:00,150 --> 06:41:58,478
the process of moving of moving back

7889
06:42:02,708 --> 06:42:00,160
into the closed position

7890
06:42:05,350 --> 06:42:02,718
and we will hear the call out for

7891
06:42:06,868 --> 06:42:05,360
whenever it has fully closed

7892
06:42:09,920 --> 06:42:06,878
and whenever

7893
06:42:09,920 --> 06:42:09,930
the latches have secured

7894
06:42:14,070 --> 06:42:12,390
[Music]

7895
06:42:16,070 --> 06:42:14,080
seeing some data it looks like it's

7896
06:42:17,990 --> 06:42:16,080
about halfway there

7897
06:42:20,230 --> 06:42:18,000
but it's opened a little bit more than

7898
06:42:23,750 --> 06:42:20,240
90 degrees i think the the exact count

7899
06:42:26,310 --> 06:42:23,760
was 110 degrees uh opening range or

7900
06:42:28,708 --> 06:42:26,320
range of motion for the nose cone

7901
06:42:42,150 --> 06:42:28,718
so we're a little more than halfway now

7902
06:42:42,160 --> 06:42:45,030
captioning not

7903
06:42:45,040 --> 06:42:46,708
nose cone available

7904
06:42:51,670 --> 06:42:49,190
so it'll take a minute for the

7905
06:42:54,230 --> 06:42:51,680
hooks to close in they close in

7906
06:42:56,548 --> 06:42:54,240
a series so the first series will close

7907
06:43:05,830 --> 06:42:56,558
and then the second will follow and that

7908
06:43:05,840 --> 06:43:27,510
so

7909
06:43:31,990 --> 06:43:29,670
all right well as we just wait for the

7910
06:43:32,788 --> 06:43:32,000
finish to that nose cone closure

7911
06:43:34,390 --> 06:43:32,798
uh

7912
06:43:36,150 --> 06:43:34,400
we'll have a bit of time again we'll

7913
06:43:39,190 --> 06:43:36,160
have about 20 minutes

7914
06:43:41,270 --> 06:43:39,200
or a little over 21 from right now

7915
06:43:43,670 --> 06:43:41,280
until we really start re-entering the

7916
06:43:45,190 --> 06:43:43,680
earth's atmosphere we're expecting that

7917
06:43:46,868 --> 06:43:45,200
entry interface

7918
06:43:48,708 --> 06:43:46,878
in about 21 minutes

7919
06:43:50,390 --> 06:43:48,718
and then right around that time we'll

7920
06:43:52,548 --> 06:43:50,400
also be looking for that blackout we've

7921
06:43:54,708 --> 06:43:52,558
been talking about we've had a little

7922
06:43:56,390 --> 06:43:54,718
bit of what we call radicom at this

7923
06:43:59,270 --> 06:43:56,400
point so you'll hear kind of some

7924
06:44:01,510 --> 06:43:59,280
sporadic uh interruptions in the audio

7925
06:44:05,030 --> 06:44:01,520
transmission just because of how dragon

7926
06:44:07,270 --> 06:44:05,040
was oriented um for the

7927
06:44:09,430 --> 06:44:07,280
the trunk jettison and for the actual

7928
06:44:11,430 --> 06:44:09,440
the orbit burn

7929
06:44:13,110 --> 06:44:11,440
but that that blackout period will be

7930
06:44:15,270 --> 06:44:13,120
due to the plasma that builds up around

7931
06:44:17,190 --> 06:44:15,280
the capsule and interfering with those

7932
06:44:25,590 --> 06:44:17,200
antennas either sending or receiving

7933
06:44:30,708 --> 06:44:27,190
so i've heard the call out that the

7934
06:44:32,948 --> 06:44:30,718
first set of hooks for nose cone closure

7935
06:44:35,270 --> 06:44:32,958
are in motion so

7936
06:44:37,110 --> 06:44:35,280
these this will complete in two sets the

7937
06:44:39,430 --> 06:44:37,120
first set is now in motion so really

7938
06:44:42,548 --> 06:44:39,440
good news to hear that

7939
06:44:44,788 --> 06:44:42,558
everything looking good so far

7940
06:44:47,030 --> 06:44:44,798
like i mentioned before

7941
06:44:49,110 --> 06:44:47,040
in the background dragon has

7942
06:44:51,270 --> 06:44:49,120
inhibited the forward

7943
06:44:53,750 --> 06:44:51,280
bulkhead draco thrusters that we just

7944
06:44:55,830 --> 06:44:53,760
used to complete that deorbit burn

7945
06:45:00,628 --> 06:44:55,840
this is to ensure that it's safe to

7946
06:45:06,070 --> 06:45:02,628
also the vehicle has initiated the

7947
06:45:08,310 --> 06:45:06,080
nitrox purge nitrox is simply a mixture

7948
06:45:09,590 --> 06:45:08,320
of nitrogen and oxygen it's what we

7949
06:45:11,030 --> 06:45:09,600
breathe

7950
06:45:12,708 --> 06:45:11,040
and the

7951
06:45:16,150 --> 06:45:12,718
the

7952
06:45:16,868 --> 06:45:16,160
system is cooled

7953
06:45:18,628 --> 06:45:16,878
so

7954
06:45:21,110 --> 06:45:18,638
allowing that cool air to circulate

7955
06:45:22,548 --> 06:45:21,120
around the cabin but also inside of bob

7956
06:45:24,310 --> 06:45:22,558
and doug's suits

7957
06:45:27,110 --> 06:45:24,320
will help to keep them cool and

7958
06:45:29,350 --> 06:45:27,120
comfortable during re-entry

7959
06:45:34,390 --> 06:45:29,360
which will be coming up in

7960
06:45:38,788 --> 06:45:36,070
we're currently tracking

7961
06:45:42,040 --> 06:45:38,798
23 minutes and 20 seconds

7962
06:45:49,750 --> 06:45:42,050
until entry begins

7963
06:45:54,948 --> 06:45:51,350
so in case you're just joining us at

7964
06:45:57,990 --> 06:45:54,958
this point the nose cone has closed

7965
06:46:00,830 --> 06:45:58,000
the forward thrusters have been

7966
06:46:03,510 --> 06:46:00,840
uh have been disabled

7967
06:46:06,150 --> 06:46:03,520
and we are

7968
06:46:08,390 --> 06:46:06,160
latching the nose cone

7969
06:46:11,830 --> 06:46:08,400
currently underway with the first set of

7970
06:46:11,840 --> 06:46:22,390
the first of two sets

7971
06:46:26,390 --> 06:46:24,230
and we just had confirmation that the

7972
06:46:29,270 --> 06:46:26,400
first set of hooks is closed so now the

7973
06:46:49,270 --> 06:46:29,280
second hit the second set will begin to

7974
06:46:53,110 --> 06:46:51,350
as we mentioned after this nose cone is

7975
06:46:54,468 --> 06:46:53,120
fully closed we'll

7976
06:46:56,948 --> 06:46:54,478
have a couple of minutes to catch our

7977
06:46:59,350 --> 06:46:56,958
breath again about 20 minutes or just

7978
06:47:02,390 --> 06:46:59,360
under 20 minutes until dragon will start

7979
06:47:04,708 --> 06:47:02,400
to maneuver itself to the entry attitude

7980
06:47:06,628 --> 06:47:04,718
essentially pointing the heat shield in

7981
06:47:08,390 --> 06:47:06,638
the direction of travel as it's going to

7982
06:47:10,548 --> 06:47:08,400
be leading the way through their reentry

7983
06:47:12,868 --> 06:47:10,558
through the earth's atmosphere

7984
06:47:15,430 --> 06:47:12,878
we'll look to run into that

7985
06:47:17,270 --> 06:47:15,440
communications blackout at about 36

7986
06:47:18,948 --> 06:47:17,280
minutes after the hour

7987
06:47:21,510 --> 06:47:18,958
expecting that to last for about six

7988
06:47:23,430 --> 06:47:21,520
minutes and then we'll get that back

7989
06:47:26,390 --> 06:47:23,440
shortly before we

7990
06:47:28,548 --> 06:47:26,400
deploy the drug parachutes followed

7991
06:47:30,868 --> 06:47:28,558
just less than a minute later by the

7992
06:47:32,708 --> 06:47:30,878
main parachutes and by that point

7993
06:47:34,468 --> 06:47:32,718
hopefully we should have some views of

7994
06:47:35,990 --> 06:47:34,478
dragon re-entering the earth's

7995
06:47:57,510 --> 06:47:36,000
atmosphere and parachuting to a

7996
06:48:01,430 --> 06:47:59,270
so there in the front row of mission

7997
06:48:02,948 --> 06:48:01,440
control in the center

7998
06:48:05,670 --> 06:48:02,958
you can see

7999
06:48:07,750 --> 06:48:05,680
ceo elon musk and our president gwen

8000
06:48:10,390 --> 06:48:07,760
shotwell sitting side by side at those

8001
06:48:12,788 --> 06:48:10,400
center consoles

8002
06:48:14,868 --> 06:48:12,798
in addition to those two the room is

8003
06:48:16,948 --> 06:48:14,878
filled with dragon operators and mission

8004
06:48:19,670 --> 06:48:16,958
leaders who are continuing to monitor

8005
06:48:21,110 --> 06:48:19,680
the health and telemetry of the crew and

8006
06:48:23,350 --> 06:48:21,120
the capsule

8007
06:48:26,310 --> 06:48:23,360
right now nose cone closure is underway

8008
06:48:28,628 --> 06:48:26,320
the first of two sets of hook latching

8009
06:48:29,510 --> 06:48:28,638
has completed

8010
06:48:31,590 --> 06:48:29,520
and

8011
06:48:42,390 --> 06:48:31,600
we just heard a call out that the spacex

8012
06:48:46,230 --> 06:48:44,150
all right great confirmation there back

8013
06:48:48,868 --> 06:48:46,240
and forth from mission control here to

8014
06:48:50,468 --> 06:48:48,878
bob and doug up in dragon endeavor

8015
06:48:52,788 --> 06:48:50,478
that bob and doug have can also

8016
06:48:55,510 --> 06:48:52,798
confirmed on their displays that the

8017
06:49:03,110 --> 06:48:55,520
nose cone has closed normally and it is

8018
06:49:07,670 --> 06:49:04,788
all right so that knows clone

8019
06:49:09,190 --> 06:49:07,680
nose cone close completion

8020
06:49:11,830 --> 06:49:09,200
a lot of tongue twisters with this right

8021
06:49:14,390 --> 06:49:11,840
now uh coming uh with dragon still

8022
06:49:17,030 --> 06:49:14,400
flying over the south pacific

8023
06:49:20,230 --> 06:49:17,040
it is on its way home we're gonna

8024
06:49:23,430 --> 06:49:20,240
gradually start to see its altitude dip

8025
06:49:25,990 --> 06:49:23,440
right now already only 207 miles over

8026
06:49:27,750 --> 06:49:26,000
the earth's surface it was at about 260

8027
06:49:28,708 --> 06:49:27,760
miles when it was still

8028
06:49:30,548 --> 06:49:28,718
over

8029
06:49:33,670 --> 06:49:30,558
on the other side of the pacific ocean

8030
06:49:35,270 --> 06:49:33,680
off the southwestern coast of australia

8031
06:49:36,788 --> 06:49:35,280
when it fired its engines for that

8032
06:49:39,270 --> 06:49:36,798
deorbit burn

8033
06:49:40,310 --> 06:49:39,280
so it's altitude going to continue to

8034
06:49:42,070 --> 06:49:40,320
drop

8035
06:49:44,230 --> 06:49:42,080
once it gets to

8036
06:49:46,868 --> 06:49:44,240
about 100 kilometers in altitude or

8037
06:49:49,030 --> 06:49:46,878
about 62 miles it's going to begin

8038
06:49:50,628 --> 06:49:49,040
what's known as entry interface

8039
06:49:51,990 --> 06:49:50,638
and that's when it really begins to

8040
06:49:54,070 --> 06:49:52,000
start to feel

8041
06:49:56,070 --> 06:49:54,080
uh the effects of the earth's atmosphere

8042
06:49:58,468 --> 06:49:56,080
will once again be experiencing lift and

8043
06:50:15,110 --> 06:49:58,478
drag as it's no longer in that near

8044
06:50:18,628 --> 06:50:17,350
so we're essentially stepping into the

8045
06:50:22,708 --> 06:50:18,638
second half

8046
06:50:27,750 --> 06:50:25,110
dragon is now beginning to flush nitrox

8047
06:50:28,628 --> 06:50:27,760
into the cabin and continuing to top it

8048
06:50:31,030 --> 06:50:28,638
off

8049
06:50:33,270 --> 06:50:31,040
in bob and doug's suits as well again

8050
06:50:35,030 --> 06:50:33,280
this is cool air essentially flowing

8051
06:50:37,510 --> 06:50:35,040
through the cabin and the suits

8052
06:50:39,990 --> 06:50:37,520
this is what will allow them and the

8053
06:50:41,750 --> 06:50:40,000
cabin itself to remain comfortable

8054
06:50:43,910 --> 06:50:41,760
during re-entry while those external

8055
06:50:45,990 --> 06:50:43,920
temperatures reach 3 500 degrees

8056
06:50:47,670 --> 06:50:46,000
fahrenheit

8057
06:50:50,150 --> 06:50:47,680
at this point in time dragon's

8058
06:50:53,110 --> 06:50:50,160
orientation is such that the heat shield

8059
06:50:54,628 --> 06:50:53,120
is pointing forward if you will

8060
06:51:01,430 --> 06:50:54,638
leading the capsule

8061
06:51:05,590 --> 06:51:03,350
if you've been following along over the

8062
06:51:07,270 --> 06:51:05,600
last couple days you know that weather

8063
06:51:09,750 --> 06:51:07,280
has been a

8064
06:51:13,030 --> 06:51:09,760
big ticket item for us

8065
06:51:16,390 --> 06:51:13,040
the recovery team has been busy over the

8066
06:51:18,948 --> 06:51:16,400
last week working to determine

8067
06:51:21,350 --> 06:51:18,958
the selection of a landing site

8068
06:51:23,430 --> 06:51:21,360
in order to increase the options for

8069
06:51:25,430 --> 06:51:23,440
space station departures

8070
06:51:28,390 --> 06:51:25,440
the team identified a total of seven

8071
06:51:30,070 --> 06:51:28,400
possible splashdown locations

8072
06:51:32,868 --> 06:51:30,080
in order to meet nasa's timeline

8073
06:51:35,430 --> 06:51:32,878
requirements for crew recovery these

8074
06:51:37,030 --> 06:51:35,440
potential splashdown locations have to

8075
06:51:38,948 --> 06:51:37,040
be closed to a port

8076
06:51:40,310 --> 06:51:38,958
and they have to be close to medical

8077
06:51:43,750 --> 06:51:40,320
facilities

8078
06:51:45,270 --> 06:51:43,760
so with all of that in mind you add the

8079
06:51:47,910 --> 06:51:45,280
ever evolving weather conditions of

8080
06:51:50,468 --> 06:51:47,920
florida but also that tropical storm

8081
06:51:52,548 --> 06:51:50,478
isaiah that was moving through

8082
06:51:54,868 --> 06:51:52,558
and it's easy to see how determining

8083
06:51:57,910 --> 06:51:54,878
that landing site is a

8084
06:52:00,230 --> 06:51:57,920
it's quite a complex process

8085
06:52:03,110 --> 06:52:00,240
since dragon is capable of splash down

8086
06:52:05,590 --> 06:52:03,120
on either side of the florida panhandle

8087
06:52:07,750 --> 06:52:05,600
we in fact have two identical and fully

8088
06:52:09,510 --> 06:52:07,760
equipped recovery vessels ready to

8089
06:52:11,430 --> 06:52:09,520
support

8090
06:52:13,990 --> 06:52:11,440
one in the gulf of mexico which is what

8091
06:52:15,990 --> 06:52:14,000
we're utilizing today go navigator and

8092
06:52:19,110 --> 06:52:16,000
the other located

8093
06:52:21,270 --> 06:52:19,120
off the east coast of florida able to

8094
06:52:24,548 --> 06:52:21,280
service landing sites in the atlantic

8095
06:52:25,830 --> 06:52:24,558
ocean that one is go searcher

8096
06:52:28,070 --> 06:52:25,840
like i mentioned today we'll be

8097
06:52:31,270 --> 06:52:28,080
splashing down in the gulf of mexico

8098
06:52:33,190 --> 06:52:31,280
just off the coast of pensacola florida

8099
06:52:35,590 --> 06:52:33,200
go navigator that recovery ship i just

8100
06:52:37,670 --> 06:52:35,600
mentioned is in place and ready and

8101
06:52:41,350 --> 06:52:37,680
waiting for bob and doug

8102
06:52:44,390 --> 06:52:41,360
the wb 57 plane if it hasn't taken off

8103
06:52:46,310 --> 06:52:44,400
already i'm sure it will be very soon

8104
06:52:48,628 --> 06:52:46,320
it's in the air okay great

8105
06:52:50,548 --> 06:52:48,638
that's what will provide our first views

8106
06:52:52,548 --> 06:52:50,558
of dragon during re-entry we'll get a

8107
06:52:54,310 --> 06:52:52,558
thermal cam off of that airplane

8108
06:52:56,310 --> 06:52:54,320
allowing us to see the capsule as it is

8109
06:52:58,310 --> 06:52:56,320
re-entering the atmosphere

8110
06:53:00,708 --> 06:52:58,320
if you were tuned in for our demo one

8111
06:53:03,270 --> 06:53:00,718
broadcast

8112
06:53:04,070 --> 06:53:03,280
there it was basically a big ball of

8113
06:53:06,310 --> 06:53:04,080
light

8114
06:53:09,350 --> 06:53:06,320
coming at us

8115
06:53:12,070 --> 06:53:09,360
we'll also have cameras on board

8116
06:53:14,830 --> 06:53:12,080
the recovery vessel so as dragon gets

8117
06:53:17,910 --> 06:53:14,840
closer uh we and is is deploying those

8118
06:53:19,750 --> 06:53:17,920
parachutes we will also be able to

8119
06:53:27,830 --> 06:53:19,760
have hopefully some really clear footage

8120
06:53:30,948 --> 06:53:29,270
all right so dragon's altitude

8121
06:53:34,070 --> 06:53:30,958
continuing to dip

8122
06:53:37,910 --> 06:53:34,080
right now about 174 miles over planet

8123
06:53:39,910 --> 06:53:37,920
earth we're under 11 and a half minutes

8124
06:53:41,510 --> 06:53:39,920
from where we expect to hit entry

8125
06:53:43,590 --> 06:53:41,520
interface so that's where dragon will

8126
06:53:46,390 --> 06:53:43,600
really start feeling the effects of

8127
06:53:47,830 --> 06:53:46,400
being in a denser atmosphere

8128
06:53:49,350 --> 06:53:47,840
and then we are still tracking that

8129
06:53:51,750 --> 06:53:49,360
blackout to come

8130
06:53:53,990 --> 06:53:51,760
right around that same time we are under

8131
06:53:56,468 --> 06:53:54,000
27 minutes away

8132
06:53:58,868 --> 06:53:56,478
from splashdown so we are under 27

8133
06:54:00,468 --> 06:53:58,878
minutes away bob and doug being on

8134
06:54:02,468 --> 06:54:00,478
planet earth for the first time since

8135
06:54:05,030 --> 06:54:02,478
may 30th

8136
06:54:07,030 --> 06:54:05,040
to kind of put everything in perspective

8137
06:54:09,350 --> 06:54:07,040
you know the dragon capsule

8138
06:54:10,310 --> 06:54:09,360
departed from the international space

8139
06:54:12,948 --> 06:54:10,320
station

8140
06:54:14,868 --> 06:54:12,958
several hours ago but

8141
06:54:16,070 --> 06:54:14,878
according to what dan just said it's

8142
06:54:17,670 --> 06:54:16,080
essentially

8143
06:54:19,430 --> 06:54:17,680
halfway home

8144
06:54:22,708 --> 06:54:19,440
just based on altitude alone so the

8145
06:54:24,788 --> 06:54:22,718
international space station is about 250

8146
06:54:26,548 --> 06:54:24,798
miles above earth's surface i think

8147
06:54:29,510 --> 06:54:26,558
right now it's between 250 and 300 i

8148
06:54:32,310 --> 06:54:29,520
think right now it's about 263 miles

8149
06:54:34,868 --> 06:54:32,320
above earth's surface so based on that

8150
06:54:37,510 --> 06:54:34,878
telemetry that dan just read off is from

8151
06:54:38,468 --> 06:54:37,520
an altitude standpoint dragon is halfway

8152
06:54:40,708 --> 06:54:38,478
home

8153
06:54:42,868 --> 06:54:40,718
and yet that second half is going to be

8154
06:54:45,350 --> 06:54:42,878
covered in the next 27

8155
06:54:47,590 --> 06:54:45,360
ish minutes uh while we wait for a

8156
06:54:49,510 --> 06:54:47,600
splashdown and recovery

8157
06:54:53,110 --> 06:54:49,520
versus the several hours that we've been

8158
06:54:55,830 --> 06:54:53,120
covering since yesterday yeah

8159
06:54:56,708 --> 06:54:55,840
yeah we will continue to see its speed

8160
06:55:00,468 --> 06:54:56,718
drop

8161
06:55:02,230 --> 06:55:00,478
starting to hit the atmosphere it's

8162
06:55:03,590 --> 06:55:02,240
starting to slow from the effects of

8163
06:55:05,830 --> 06:55:03,600
that friction

8164
06:55:07,590 --> 06:55:05,840
generating the heat on the heat shield

8165
06:55:09,430 --> 06:55:07,600
building up the plasma eventually around

8166
06:55:11,750 --> 06:55:09,440
the spacecraft its speed is going to

8167
06:55:14,390 --> 06:55:11,760
continue to drop it's already below 17

8168
06:55:16,270 --> 06:55:14,400
000 miles an hour and it'll drop to

8169
06:55:19,590 --> 06:55:16,280
essentially a terminal velocity of about

8170
06:55:21,670 --> 06:55:19,600
350 miles an hour right as those drogue

8171
06:55:22,390 --> 06:55:21,680
shoots deploy and those are going to pop

8172
06:55:25,190 --> 06:55:22,400
out

8173
06:55:27,830 --> 06:55:25,200
when sensors on the dragon spacecraft

8174
06:55:29,670 --> 06:55:27,840
both gps and pressure sensors tell the

8175
06:55:31,750 --> 06:55:29,680
spacecraft it's at the right altitude

8176
06:55:33,990 --> 06:55:31,760
and then those will automatically deploy

8177
06:55:36,628 --> 06:55:34,000
those droves coming out of the top

8178
06:55:39,110 --> 06:55:36,638
section of the spacecraft by using two

8179
06:55:41,030 --> 06:55:39,120
mortars or pyrotechnics essentially to

8180
06:55:44,390 --> 06:55:41,040
deploy those to do the initial slowing

8181
06:55:46,150 --> 06:55:44,400
and stabilizing of the dragon capsule

8182
06:55:48,310 --> 06:55:46,160
and then after that the main parachutes

8183
06:55:52,150 --> 06:55:48,320
will pop out and further decelerate it

8184
06:55:53,910 --> 06:55:52,160
to about 119 miles per hour

8185
06:55:55,670 --> 06:55:53,920
and then that will continue to

8186
06:55:58,230 --> 06:55:55,680
decelerate and by the time that the

8187
06:56:01,190 --> 06:55:58,240
capsule is splashing down in the gulf of

8188
06:56:03,750 --> 06:56:01,200
mexico it's only going 15 16 miles per

8189
06:56:04,628 --> 06:56:03,760
hour so significant reduction in speed

8190
06:56:06,390 --> 06:56:04,638
there

8191
06:56:07,430 --> 06:56:06,400
over over just the course of a couple

8192
06:56:09,750 --> 06:56:07,440
minutes

8193
06:56:11,110 --> 06:56:09,760
that of course is you know a pretty

8194
06:56:13,590 --> 06:56:11,120
comfortable speed

8195
06:56:14,948 --> 06:56:13,600
uh the way that the astronauts have

8196
06:56:17,510 --> 06:56:14,958
described it

8197
06:56:20,070 --> 06:56:17,520
previously with other other

8198
06:56:21,110 --> 06:56:20,080
types of missions also landing down

8199
06:56:23,190 --> 06:56:21,120
doing

8200
06:56:25,190 --> 06:56:23,200
land landings at about the same rate

8201
06:56:27,750 --> 06:56:25,200
they said it feels like you're in a a

8202
06:56:29,430 --> 06:56:27,760
minor fender bender

8203
06:56:31,670 --> 06:56:29,440
yeah you're definitely running into

8204
06:56:33,830 --> 06:56:31,680
something you'll feel it but uh they do

8205
06:56:35,750 --> 06:56:33,840
a lot of work uh with the seats and the

8206
06:56:36,948 --> 06:56:35,760
restraints with these crew members just

8207
06:56:38,230 --> 06:56:36,958
to make sure

8208
06:56:39,750 --> 06:56:38,240
um

8209
06:56:41,830 --> 06:56:39,760
while it may be a fender bender you've

8210
06:56:43,990 --> 06:56:41,840
got more than a seat belt essentially

8211
06:56:45,510 --> 06:56:44,000
holding you in so they are they're very

8212
06:56:47,110 --> 06:56:45,520
secure in their suits and in their seats

8213
06:56:49,110 --> 06:56:47,120
and they're going to stay in there even

8214
06:56:51,270 --> 06:56:49,120
after dragon touches down we'll still

8215
06:56:53,030 --> 06:56:51,280
have communication with dragon once

8216
06:56:54,070 --> 06:56:53,040
they're in the water it'll stay powered

8217
06:56:55,430 --> 06:56:54,080
on

8218
06:56:57,510 --> 06:56:55,440
probably most importantly their air

8219
06:56:59,270 --> 06:56:57,520
conditioner will continue to work

8220
06:57:01,110 --> 06:56:59,280
while they're in the capsule

8221
06:57:03,190 --> 06:57:01,120
in the now gulf of mexico and much

8222
06:57:04,708 --> 06:57:03,200
warmer temperatures than

8223
06:57:06,548 --> 06:57:04,718
they've seen for

8224
06:57:07,990 --> 06:57:06,558
the last couple of months

8225
06:57:09,830 --> 06:57:08,000
and we'll still be able to talk to them

8226
06:57:12,830 --> 06:57:09,840
from here in hawthorne and the recovery

8227
06:57:15,990 --> 06:57:12,840
teams will be able to as well

8228
06:57:18,868 --> 06:57:16,000
yeah one of the things we might see them

8229
06:57:20,230 --> 06:57:18,878
do uh depending on

8230
06:57:22,070 --> 06:57:20,240
sea states and everything after they

8231
06:57:23,110 --> 06:57:22,080
touch down on the crew themselves

8232
06:57:25,510 --> 06:57:23,120
they'll still have a couple of

8233
06:57:26,230 --> 06:57:25,520
demonstration tasks potentially to carry

8234
06:57:28,948 --> 06:57:26,240
out

8235
06:57:31,350 --> 06:57:28,958
they have a satellite phone inside of

8236
06:57:34,070 --> 06:57:31,360
the capsule that has its own

8237
06:57:36,708 --> 06:57:34,080
satellite antenna integrated into dragon

8238
06:57:39,270 --> 06:57:36,718
and they're able to use that independent

8239
06:57:41,430 --> 06:57:39,280
of dragon's communication system so one

8240
06:57:43,670 --> 06:57:41,440
thing we might hear them do is do a test

8241
06:57:45,190 --> 06:57:43,680
call on that to the teams here

8242
06:57:47,510 --> 06:57:45,200
in hawthorne we wouldn't be able to hear

8243
06:57:49,590 --> 06:57:47,520
the call but you would hear the the go

8244
06:57:51,270 --> 06:57:49,600
to do it over the dragon to ground audio

8245
06:57:52,868 --> 06:57:51,280
that we've been listening to this entire

8246
06:57:54,708 --> 06:57:52,878
time so

8247
06:57:57,270 --> 06:57:54,718
still have a couple of demonstration

8248
06:57:59,750 --> 06:57:57,280
steps essentially as again this is a

8249
06:58:01,990 --> 06:57:59,760
test flight this is the flight to really

8250
06:58:04,788 --> 06:58:02,000
prove out dragon systems to bring crew

8251
06:58:06,708 --> 06:58:04,798
members from kennedy space center to the

8252
06:58:07,510 --> 06:58:06,718
space station and return them safely to

8253
06:58:09,910 --> 06:58:07,520
earth

8254
06:58:11,270 --> 06:58:09,920
and so far we have had a flawless ride

8255
06:58:13,590 --> 06:58:11,280
downhill

8256
06:58:16,468 --> 06:58:13,600
we've completed the deorbit burn

8257
06:58:19,350 --> 06:58:16,478
dragon is continuing to drop down it's

8258
06:58:21,670 --> 06:58:19,360
right now at about 132 miles over the

8259
06:58:23,990 --> 06:58:21,680
pacific ocean pretty soon we're gonna

8260
06:58:26,868 --> 06:58:24,000
see its ground track cross over central

8261
06:58:29,510 --> 06:58:26,878
america out over the gulf i'll remain in

8262
06:58:39,670 --> 06:58:29,520
that splash down in the gulf just off

8263
06:58:39,680 --> 06:58:47,830
dragon spacex for entry brief

8264
06:58:51,590 --> 06:58:49,750
okay doug we have no update to timing

8265
06:58:53,590 --> 06:58:51,600
because the burn went great and your

8266
06:59:01,750 --> 06:58:53,600
vehicle is still looking really good for

8267
06:59:07,590 --> 06:59:04,868
okay dragon copy thank you

8268
06:59:09,990 --> 06:59:07,600
in addition the recovery team is go and

8269
06:59:11,990 --> 06:59:10,000
the weather is still great uh winds are

8270
06:59:14,468 --> 06:59:12,000
about two knots and waves about

8271
06:59:20,628 --> 06:59:14,478
one foot from the ship they're reporting

8272
06:59:24,788 --> 06:59:22,468
trapping good weather at the landing

8273
06:59:27,190 --> 06:59:24,798
area thank you

8274
06:59:29,110 --> 06:59:27,200
okay and the last piece is that we do

8275
06:59:32,390 --> 06:59:29,120
expect some additional ready com during

8276
06:59:34,788 --> 06:59:32,400
entry prep 2 due to vehicle attitude

8277
06:59:37,270 --> 06:59:34,798
um so if you can get us your entry check

8278
06:59:43,110 --> 06:59:37,280
uh report a little bit prior to entry

8279
06:59:48,230 --> 06:59:45,350
we'll go

8280
06:59:50,390 --> 06:59:48,240
okay thanks doug

8281
06:59:53,430 --> 06:59:50,400
so there we just had a bit of a briefing

8282
06:59:55,590 --> 06:59:53,440
between mission control and bob and doug

8283
06:59:58,150 --> 06:59:55,600
up in crew endeavor

8284
07:00:01,510 --> 06:59:58,160
just confirming with them that the

8285
07:00:03,510 --> 07:00:01,520
deorbit burn was great and that the

8286
07:00:04,628 --> 07:00:03,520
timing on their pads doesn't need to be

8287
07:00:07,270 --> 07:00:04,638
updated

8288
07:00:10,150 --> 07:00:07,280
we are able to upload new trajectory

8289
07:00:12,390 --> 07:00:10,160
calculations including times that remain

8290
07:00:14,708 --> 07:00:12,400
live depending on

8291
07:00:16,548 --> 07:00:14,718
you know how the burn goes and at this

8292
07:00:18,628 --> 07:00:16,558
point in time those don't need to be

8293
07:00:21,030 --> 07:00:18,638
updated it is important that they do

8294
07:00:24,310 --> 07:00:21,040
remain accurate because bob and doug

8295
07:00:26,150 --> 07:00:24,320
their primary mission right now is to

8296
07:00:28,628 --> 07:00:26,160
continue to monitor

8297
07:00:30,468 --> 07:00:28,638
the vehicle status and telemetry and

8298
07:00:32,628 --> 07:00:30,478
data being presented to them on their

8299
07:00:34,070 --> 07:00:32,638
touch on their touch screen displays in

8300
07:00:35,590 --> 07:00:34,080
front of them

8301
07:00:37,670 --> 07:00:35,600
and so

8302
07:00:39,510 --> 07:00:37,680
during the more dynamic events

8303
07:00:41,110 --> 07:00:39,520
they certainly want to be aware when

8304
07:00:43,190 --> 07:00:41,120
things like parachute deploy will be

8305
07:00:45,110 --> 07:00:43,200
happening and when splashed down as is

8306
07:00:47,350 --> 07:00:45,120
expected so making sure that the

8307
07:00:49,350 --> 07:00:47,360
timeline of events the sequencing is

8308
07:00:51,990 --> 07:00:49,360
accurate is certainly important in order

8309
07:00:56,708 --> 07:00:52,000
for them to stay aware and updated of

8310
07:01:00,948 --> 07:00:58,948
just another quick position check

8311
07:01:02,230 --> 07:01:00,958
dragon's still out over the central

8312
07:01:06,150 --> 07:01:02,240
pacific

8313
07:01:08,070 --> 07:01:06,160
down to about 108 miles in altitude and

8314
07:01:10,310 --> 07:01:08,080
we're expecting that entry interface

8315
07:01:12,230 --> 07:01:10,320
come up in the next four minutes or so

8316
07:01:14,548 --> 07:01:12,240
again at that point dragon should be in

8317
07:01:17,670 --> 07:01:14,558
an altitude of right around 62 statute

8318
07:01:19,430 --> 07:01:17,680
miles or about 100 kilometers and that's

8319
07:01:21,190 --> 07:01:19,440
when it really starts to feel the

8320
07:01:22,310 --> 07:01:21,200
effects of the atmosphere it starts to

8321
07:01:24,390 --> 07:01:22,320
experience

8322
07:01:28,628 --> 07:01:24,400
the

8323
07:01:31,590 --> 07:01:28,638
effects it's been free from while flying

8324
07:01:34,390 --> 07:01:31,600
in the near vacuum of low earth orbit

8325
07:01:37,430 --> 07:01:34,400
so continuing to drop in altitude

8326
07:01:47,430 --> 07:01:37,440
still looking for an on time splashdown

8327
07:01:51,030 --> 07:01:49,190
and just a reminder we do have that

8328
07:01:53,110 --> 07:01:51,040
blackout period coming so as they

8329
07:01:55,110 --> 07:01:53,120
continue to dip in the earth's

8330
07:01:56,548 --> 07:01:55,120
atmosphere and get lower and lower the

8331
07:01:58,468 --> 07:01:56,558
atmosphere gets thicker and thicker and

8332
07:02:00,628 --> 07:01:58,478
it's going to generate more and more

8333
07:02:03,590 --> 07:02:00,638
heat eventually heating up the outside

8334
07:02:05,830 --> 07:02:03,600
of dragon to 3 500 degrees fahrenheit

8335
07:02:07,750 --> 07:02:05,840
and as it hits that peak heating it'll

8336
07:02:10,230 --> 07:02:07,760
also be forming a plasma around the

8337
07:02:12,230 --> 07:02:10,240
spacecraft so we do expect to lose calm

8338
07:02:17,190 --> 07:02:12,240
for about six minutes

8339
07:02:22,788 --> 07:02:19,510
spacex copies entry prep complete thank

8340
07:02:27,830 --> 07:02:25,110
the call from spacecraft commander doug

8341
07:02:29,510 --> 07:02:27,840
hurley entry preps are complete

8342
07:02:31,350 --> 07:02:29,520
so they are on board they are monitoring

8343
07:02:33,910 --> 07:02:31,360
they are ready to come home

8344
07:02:36,468 --> 07:02:33,920
yeah and as of right now uh entry prep

8345
07:02:38,150 --> 07:02:36,478
should have also included a final

8346
07:02:39,430 --> 07:02:38,160
configuration of their flight suits so

8347
07:02:41,510 --> 07:02:39,440
we had a question

8348
07:02:44,150 --> 07:02:41,520
from our social media earlier if the

8349
07:02:45,910 --> 07:02:44,160
visors will be up or down

8350
07:02:46,788 --> 07:02:45,920
those visors should be down at this

8351
07:03:04,868 --> 07:02:46,798
point

8352
07:03:08,868 --> 07:03:06,628
in that last briefing we also heard that

8353
07:03:11,590 --> 07:03:08,878
the weather is looking good

8354
07:03:13,590 --> 07:03:11,600
in a previous report the phrasing was it

8355
07:03:16,390 --> 07:03:13,600
looks like glass

8356
07:03:19,830 --> 07:03:16,400
and that is certainly ideal for a water

8357
07:03:21,030 --> 07:03:19,840
splashdown that being said the recovery

8358
07:03:23,510 --> 07:03:21,040
timeline

8359
07:03:25,350 --> 07:03:23,520
you know bob and doug should be out of

8360
07:03:26,788 --> 07:03:25,360
the capsule within an hour after

8361
07:03:29,030 --> 07:03:26,798
splashing down

8362
07:03:31,590 --> 07:03:29,040
so good to hear that the weather is good

8363
07:03:33,510 --> 07:03:31,600
we saw blue skies and a couple of white

8364
07:03:35,270 --> 07:03:33,520
fluffy clouds out there

8365
07:03:39,670 --> 07:03:35,280
in the gulf of mexico as we got views

8366
07:03:41,350 --> 07:03:39,680
from our recovery vessel go navigator

8367
07:03:42,868 --> 07:03:41,360
but glad to hear that conditions are

8368
07:03:43,990 --> 07:03:42,878
sustaining

8369
07:03:46,468 --> 07:03:44,000
and that

8370
07:03:48,548 --> 07:03:46,478
winds also are looking really good

8371
07:03:50,070 --> 07:03:48,558
around two and two two and a half miles

8372
07:03:51,670 --> 07:03:50,080
per hour so

8373
07:03:52,868 --> 07:03:51,680
hardly anything at all

8374
07:03:55,270 --> 07:03:52,878
really couldn't ask for better

8375
07:03:56,948 --> 07:03:55,280
conditions for a splashdown day we we

8376
07:03:58,548 --> 07:03:56,958
kind of threaded the needle once again

8377
07:04:01,270 --> 07:03:58,558
almost like we did on launch with the

8378
07:04:03,590 --> 07:04:01,280
weather today you

8379
07:04:06,070 --> 07:04:03,600
your upper limits for wind were about 10

8380
07:04:08,548 --> 07:04:06,080
miles an hour so we're we're well behold

8381
07:04:12,948 --> 07:04:08,558
below that threshold for a splashdown

8382
07:04:18,948 --> 07:04:16,070
the dragon coming up on 82 miles in

8383
07:04:20,948 --> 07:04:18,958
altitude continuing to dip down

8384
07:04:22,548 --> 07:04:20,958
we're expecting that entry interface to

8385
07:04:24,390 --> 07:04:22,558
start pretty soon

8386
07:04:25,830 --> 07:04:24,400
where the vehicle itself is really going

8387
07:04:27,670 --> 07:04:25,840
to start heating up

8388
07:04:30,070 --> 07:04:27,680
it's going to continue to use its draco

8389
07:04:32,708 --> 07:04:30,080
thrusters to maintain its attitude as it

8390
07:04:34,548 --> 07:04:32,718
continues through the earth's atmosphere

8391
07:04:45,990 --> 07:04:34,558
and we'll have that calm blackout coming

8392
07:04:49,910 --> 07:04:48,230
so the cabin purge has started again

8393
07:04:52,150 --> 07:04:49,920
this is when they're going to

8394
07:04:53,910 --> 07:04:52,160
flush the cabin of dragon with cooled

8395
07:04:54,868 --> 07:04:53,920
air they're also going to do a suit

8396
07:04:56,788 --> 07:04:54,878
purge

8397
07:04:58,868 --> 07:04:56,798
running cooled nitrox through the suits

8398
07:05:00,628 --> 07:04:58,878
for bob and doug just to keep things at

8399
07:05:02,548 --> 07:05:00,638
a comfortable temperature for them as

8400
07:05:26,788 --> 07:05:02,558
the capsule goes through the re-entry

8401
07:05:31,270 --> 07:05:28,868
so like we said we are anticipating a

8402
07:05:33,670 --> 07:05:31,280
brief blackout period where we're unable

8403
07:05:35,430 --> 07:05:33,680
to communicate with the capsule that's

8404
07:05:37,430 --> 07:05:35,440
uh we're expecting that to start in

8405
07:05:40,548 --> 07:05:37,440
exactly three minutes

8406
07:05:42,548 --> 07:05:40,558
that will last for six minutes total and

8407
07:05:45,830 --> 07:05:42,558
during that time we will be unable to

8408
07:05:47,990 --> 07:05:45,840
command the vehicle or receive telemetry

8409
07:05:50,070 --> 07:05:48,000
that being said dragon is designed to be

8410
07:05:52,468 --> 07:05:50,080
fully autonomous so

8411
07:05:53,910 --> 07:05:52,478
it's driving itself anyway

8412
07:05:55,270 --> 07:05:53,920
so bob and doug

8413
07:05:57,270 --> 07:05:55,280
will

8414
07:05:58,868 --> 07:05:57,280
stay fastened in their seats

8415
07:06:01,430 --> 07:05:58,878
and like i said that

8416
07:06:03,110 --> 07:06:01,440
anticipated loss of signal or as you'll

8417
07:06:04,788 --> 07:06:03,120
hear it called los

8418
07:06:09,190 --> 07:06:04,798
is anticipated to

8419
07:06:13,190 --> 07:06:11,990
during that blackout period the capsule

8420
07:06:16,310 --> 07:06:13,200
will

8421
07:06:19,590 --> 07:06:16,320
interface

8422
07:06:21,350 --> 07:06:19,600
this is when the capsule is now

8423
07:06:24,468 --> 07:06:21,360
really in the earth's atmosphere and

8424
07:06:27,270 --> 07:06:24,478
beginning to be subject to aerodynamic

8425
07:06:29,430 --> 07:06:27,280
forces this is also when a lot of that

8426
07:06:31,510 --> 07:06:29,440
friction will begin to build up and

8427
07:06:33,750 --> 07:06:31,520
raise the external temperatures dragon

8428
07:06:35,910 --> 07:06:33,760
spacex we showed two minutes until

8429
07:06:44,390 --> 07:06:35,920
predicted calm blackout we will see you

8430
07:06:50,628 --> 07:06:47,270
dragon cappies 1842 we'll talk to you

8431
07:06:55,510 --> 07:06:52,468
so there's that heads up

8432
07:06:58,230 --> 07:06:55,520
communication from mission control to

8433
07:07:02,708 --> 07:06:58,240
dragon endeavor confirming that coms

8434
07:07:05,750 --> 07:07:04,310
like i was saying during the blackout

8435
07:07:09,270 --> 07:07:05,760
the dragon capsule will be going through

8436
07:07:11,670 --> 07:07:09,280
entry interface where it is encountering

8437
07:07:13,510 --> 07:07:11,680
aerodynamic forces

8438
07:07:16,070 --> 07:07:13,520
really starting to build up

8439
07:07:17,910 --> 07:07:16,080
the external temperature as it and that

8440
07:07:21,590 --> 07:07:17,920
external temperature will reach about 3

8441
07:07:26,390 --> 07:07:23,750
however the the the interior of the

8442
07:07:28,468 --> 07:07:26,400
cabin is environmentally cooled so bob

8443
07:07:30,868 --> 07:07:28,478
and doug will should be should remain

8444
07:07:33,110 --> 07:07:30,878
comfortable during their descent

8445
07:07:34,628 --> 07:07:33,120
there will be cool air flowing not only

8446
07:07:39,270 --> 07:07:34,638
through the cabin itself but also

8447
07:07:44,390 --> 07:07:41,030
the suits have sensors on them that are

8448
07:07:47,030 --> 07:07:44,400
able to detect the temperature inside

8449
07:07:48,070 --> 07:07:47,040
that suit and once it once

8450
07:07:49,110 --> 07:07:48,080
that

8451
07:07:50,468 --> 07:07:49,120
sensor

8452
07:07:51,990 --> 07:07:50,478
reads that

8453
07:07:53,510 --> 07:07:52,000
it has reached the the maximum

8454
07:07:55,830 --> 07:07:53,520
temperature threshold

8455
07:07:56,628 --> 07:07:55,840
it'll flush the suit with some cool air

8456
07:08:04,070 --> 07:07:56,638
and

8457
07:08:09,190 --> 07:08:05,750
all right well we are right around that

8458
07:08:10,788 --> 07:08:09,200
estimated blackout time

8459
07:08:13,270 --> 07:08:10,798
as we heard the call we'll see them on

8460
07:08:14,468 --> 07:08:13,280
the other side expected to regain that

8461
07:08:18,628 --> 07:08:14,478
communication

8462
07:08:20,390 --> 07:08:18,638
at about 42 minutes after the hour

8463
07:08:23,670 --> 07:08:20,400
so for these next six minutes they're

8464
07:08:25,910 --> 07:08:23,680
already less than 60 miles in altitude

8465
07:08:28,230 --> 07:08:25,920
and this is when the capsule is really

8466
07:08:30,468 --> 07:08:28,240
heating up during that reentry reaching

8467
07:08:33,750 --> 07:08:30,478
temperatures of around

8468
07:08:35,510 --> 07:08:33,760
3 500 degrees fahrenheit as again you're

8469
07:08:38,310 --> 07:08:35,520
essentially hitting the atmosphere more

8470
07:08:40,070 --> 07:08:38,320
than 17 000 miles an hour and the

8471
07:08:41,430 --> 07:08:40,080
friction building up that plasma around

8472
07:08:43,750 --> 07:08:41,440
the spacecraft that's what's going to

8473
07:08:45,590 --> 07:08:43,760
prevent us from talking to bob and doug

8474
07:08:47,910 --> 07:08:45,600
or getting data back from the spacecraft

8475
07:08:49,990 --> 07:08:47,920
for the next six minutes

8476
07:08:51,990 --> 07:08:50,000
flight computers are in control though

8477
07:08:54,868 --> 07:08:52,000
it's going to continue to maintain its

8478
07:08:57,510 --> 07:08:54,878
appropriate trajectory and attitude

8479
07:08:59,190 --> 07:08:57,520
having attitude determination devices on

8480
07:09:01,350 --> 07:08:59,200
board the capsule not reliant on

8481
07:09:03,430 --> 07:09:01,360
communications with satellites

8482
07:09:06,310 --> 07:09:03,440
and it's going to continue dragging down

8483
07:09:08,390 --> 07:09:06,320
the correct path for this splashdown off

8484
07:09:10,948 --> 07:09:08,400
the coast of pensacola so

8485
07:09:13,110 --> 07:09:10,958
we are in that black out period we're

8486
07:09:39,190 --> 07:09:13,120
going to continue to stand by until we

8487
07:09:44,548 --> 07:09:41,350
all right and just about two minutes

8488
07:09:46,310 --> 07:09:44,558
after we get acquisition of signal aos

8489
07:09:47,830 --> 07:09:46,320
back with dragon we're going to be

8490
07:09:49,350 --> 07:09:47,840
looking for those parachutes and we

8491
07:09:51,030 --> 07:09:49,360
should hopefully be getting some views

8492
07:09:54,628 --> 07:09:51,040
from a couple of our assets out at the

8493
07:09:56,310 --> 07:09:54,638
landing zone including our wb 57 high

8494
07:09:57,190 --> 07:09:56,320
altitude research plane which is going

8495
07:09:59,110 --> 07:09:57,200
to be

8496
07:10:01,430 --> 07:09:59,120
relying on dragon's telemetry to

8497
07:10:03,350 --> 07:10:01,440
actually lock onto it in the sky and

8498
07:10:05,590 --> 07:10:03,360
give us an infrared view of the capsule

8499
07:10:06,868 --> 07:10:05,600
during the final stages of re-entry

8500
07:10:09,270 --> 07:10:06,878
we're going to be looking for the drogue

8501
07:10:11,190 --> 07:10:09,280
deploys at about 44 minutes after the

8502
07:10:12,070 --> 07:10:11,200
hour those will be two drogue shoots

8503
07:10:14,310 --> 07:10:12,080
they're going to come out when the

8504
07:10:17,030 --> 07:10:14,320
vehicle is still moving in about 350

8505
07:10:20,150 --> 07:10:17,040
miles an hour it'll be in an altitude of

8506
07:10:22,070 --> 07:10:20,160
about 18 000 feet they'll come out and

8507
07:10:25,190 --> 07:10:22,080
do some initial slowing and

8508
07:10:27,510 --> 07:10:25,200
stabilization of the spacecraft and then

8509
07:10:29,750 --> 07:10:27,520
less than a minute later they'll detach

8510
07:10:32,150 --> 07:10:29,760
and the four main parachutes will deploy

8511
07:10:33,830 --> 07:10:32,160
you'll see them come out and look kind

8512
07:10:36,390 --> 07:10:33,840
of closed up initially and then they'll

8513
07:10:38,868 --> 07:10:36,400
do what's known as reefing opening up in

8514
07:10:40,788 --> 07:10:38,878
really two different stages just to

8515
07:10:42,708 --> 07:10:40,798
minimize the immediate loads on the

8516
07:10:44,788 --> 07:10:42,718
parachutes themselves

8517
07:10:47,670 --> 07:10:44,798
those main parachutes will come out at

8518
07:10:50,070 --> 07:10:47,680
an altitude of about 6 500 feet with

8519
07:10:52,310 --> 07:10:50,080
dragon already slowed down to 119 miles

8520
07:10:54,390 --> 07:10:52,320
an hour and they'll do the rest of the

8521
07:10:58,230 --> 07:10:54,400
slowing the whole way down until we

8522
07:10:59,350 --> 07:10:58,240
splash down in the gulf of mexico we

8523
07:11:01,670 --> 07:10:59,360
should be

8524
07:11:11,350 --> 07:11:01,680
10 minutes away

8525
07:11:17,110 --> 07:11:13,590
so right now we're getting our cameras

8526
07:11:18,230 --> 07:11:17,120
on the wb 57 airplane which is in the

8527
07:11:20,150 --> 07:11:18,240
area

8528
07:11:35,350 --> 07:11:20,160
getting those cameras ready to give us

8529
07:11:38,708 --> 07:11:37,190
and we should still have about three

8530
07:11:39,670 --> 07:11:38,718
minutes left little less than three

8531
07:11:41,990 --> 07:11:39,680
minutes

8532
07:11:43,910 --> 07:11:42,000
until we anticipate reacquiring our

8533
07:11:46,788 --> 07:11:43,920
signal and our connection with bob and

8534
07:11:48,468 --> 07:11:46,798
doug in the dragon spacecraft

8535
07:11:51,270 --> 07:11:48,478
if you're just tuning in we are in a

8536
07:11:53,670 --> 07:11:51,280
blackout period that we were expecting

8537
07:11:55,430 --> 07:11:53,680
this blackout period will last a total

8538
07:11:57,110 --> 07:11:55,440
of six minutes and we're about halfway

8539
07:11:59,350 --> 07:11:57,120
through there now

8540
07:12:02,150 --> 07:11:59,360
at the moment dragon

8541
07:12:03,910 --> 07:12:02,160
is re-entering the earth's atmosphere

8542
07:12:05,750 --> 07:12:03,920
and due to the plasma building up on the

8543
07:12:07,750 --> 07:12:05,760
exterior of the vehicle

8544
07:12:10,150 --> 07:12:07,760
we're unable to communicate or send

8545
07:12:13,190 --> 07:12:10,160
commands but dragon is fully autonomous

8546
07:12:15,190 --> 07:12:13,200
it is steering itself

8547
07:12:46,868 --> 07:12:15,200
and right now bob and doug are flying

8548
07:12:46,878 --> 07:12:54,370
dragon spacex com check

8549
07:12:54,380 --> 07:12:59,590
[Music]

8550
07:13:03,910 --> 07:13:01,910
so we're still inside that anticipated

8551
07:13:05,110 --> 07:13:03,920
blackout window it does look like we are

8552
07:13:07,190 --> 07:13:05,120
getting

8553
07:13:09,670 --> 07:13:07,200
maybe some sporadic data starting to

8554
07:13:17,590 --> 07:13:09,680
peak through this is why you heard that

8555
07:13:17,600 --> 07:13:23,350
dragon spacex comm check

8556
07:13:29,510 --> 07:13:25,190
doctor as you're loud and clear we're

8557
07:13:34,230 --> 07:13:31,910
copy we've got you five by five as well

8558
07:13:38,650 --> 07:13:34,240
doug looking good and you can expect an

8559
07:13:38,660 --> 07:13:42,070
[Music]

8560
07:13:45,670 --> 07:13:43,990
all right really good news there we have

8561
07:13:47,750 --> 07:13:45,680
come out of the blackout period and we

8562
07:13:50,548 --> 07:13:47,760
have reestablished connection with

8563
07:14:01,190 --> 07:13:50,558
dragon endeavor with nasa astronauts bob

8564
07:14:04,230 --> 07:14:02,548
we were able to reacquire that

8565
07:14:05,430 --> 07:14:04,240
communication a little bit earlier than

8566
07:14:08,310 --> 07:14:05,440
expected

8567
07:14:09,430 --> 07:14:08,320
and now we are just waiting we should

8568
07:14:11,190 --> 07:14:09,440
just be

8569
07:14:13,670 --> 07:14:11,200
about two and a half minutes away from

8570
07:14:17,110 --> 07:14:13,680
that initial drogue shoot deploy

8571
07:14:21,740 --> 07:14:17,120
yeah two minutes and 26 seconds

8572
07:14:25,910 --> 07:14:24,548
[Music]

8573
07:14:29,670 --> 07:14:25,920
you may have heard earlier that bob and

8574
07:14:31,110 --> 07:14:29,680
doug are currently experiencing 3.5 g's

8575
07:14:36,150 --> 07:14:31,120
not too bad that's about what they

8576
07:14:36,160 --> 07:14:43,990
just like a mild roller coaster

8577
07:14:48,390 --> 07:14:46,310
so the vehicle is now over the gulf of

8578
07:14:50,150 --> 07:14:48,400
mexico

8579
07:14:52,150 --> 07:14:50,160
it is approaching

8580
07:14:53,910 --> 07:14:52,160
the landing zone off the coast of

8581
07:14:58,070 --> 07:14:53,920
florida near pensacola and there we have

8582
07:15:03,670 --> 07:14:59,590
it is this

8583
07:15:05,110 --> 07:15:03,680
the first view from the wb 57 airplane

8584
07:15:06,468 --> 07:15:05,120
it is dipping in and out a little bit

8585
07:15:11,270 --> 07:15:06,478
this is going to be an infrared camera

8586
07:15:17,110 --> 07:15:14,150
we have that comeback with bob and doug

8587
07:15:18,468 --> 07:15:17,120
you heard egps is converging

8588
07:15:21,590 --> 07:15:18,478
dragon has

8589
07:15:23,190 --> 07:15:21,600
three gps units that it uses

8590
07:15:25,830 --> 07:15:23,200
actually in the parachute deployment

8591
07:15:27,910 --> 07:15:25,840
process as it helps

8592
07:15:30,468 --> 07:15:27,920
along with the pressure sensors really

8593
07:15:32,070 --> 07:15:30,478
give a solid altitude to the flight

8594
07:15:36,948 --> 07:15:32,080
computers on when these are supposed to

8595
07:15:41,990 --> 07:15:39,590
we're standing by for the drogue shoot

8596
07:15:47,430 --> 07:15:42,000
deployments we should be just under five

8597
07:15:57,350 --> 07:15:49,990
passing 15 kilometers brace for drogue

8598
07:16:02,548 --> 07:15:59,830
about 14 kilometers in altitude 8.4

8599
07:16:04,390 --> 07:16:02,558
miles continuing to descend

8600
07:16:07,350 --> 07:16:04,400
there on your screen we have a shot of

8601
07:16:09,110 --> 07:16:07,360
the capsule as it is preparing to deploy

8602
07:16:11,350 --> 07:16:09,120
those initial parachutes the drug

8603
07:16:15,750 --> 07:16:11,360
parachutes

8604
07:16:17,270 --> 07:16:15,760
vehicle down

8605
07:16:19,430 --> 07:16:17,280
even further

8606
07:16:29,670 --> 07:16:19,440
and help stabilize in preparation for

8607
07:16:35,190 --> 07:16:31,510
right about now the capsule is going

8608
07:16:41,990 --> 07:16:35,200
about 400 miles per hour

8609
07:16:42,000 --> 07:16:52,230
and standing by for drug deploys

8610
07:16:56,310 --> 07:16:54,948
visual two drugs out

8611
07:16:57,670 --> 07:16:56,320
there on your screen we have visual

8612
07:16:59,670 --> 07:16:57,680
confirmation of those two drug

8613
07:17:01,990 --> 07:16:59,680
deployments

8614
07:17:04,230 --> 07:17:02,000
all right so two of two the drugs now

8615
07:17:07,030 --> 07:17:04,240
out they're gonna do their slowing and

8616
07:17:09,430 --> 07:17:07,040
stabilizing of the dragon spacecraft

8617
07:17:11,350 --> 07:17:09,440
they should be detaching in just a few

8618
07:17:14,388 --> 07:17:11,360
moments and then we'll see four

8619
07:17:16,830 --> 07:17:14,398
parachutes the main parachutes deployed

8620
07:17:24,548 --> 07:17:16,840
dragon under

8621
07:17:28,070 --> 07:17:26,388
so the expected descent rate the

8622
07:17:31,270 --> 07:17:28,080
expected velocity out of the droves

8623
07:17:33,350 --> 07:17:31,280
nominal we're right at around 150 miles

8624
07:17:37,510 --> 07:17:33,360
an hour and already dropping

8625
07:17:39,910 --> 07:17:37,520
you can see the droves now detach

8626
07:17:43,270 --> 07:17:39,920
there we have confirmation of deployment

8627
07:17:47,110 --> 07:17:43,280
of the four main parachutes

8628
07:17:48,070 --> 07:17:47,120
we are visual on four shoots out we are

8629
07:18:05,030 --> 07:17:48,080
visual

8630
07:18:09,830 --> 07:18:06,868
so at this point the main parachutes

8631
07:18:11,990 --> 07:18:09,840
have deployed they are inflating as you

8632
07:18:16,548 --> 07:18:12,000
can see there on your screen continuing

8633
07:18:21,590 --> 07:18:18,708
we are anticipating splashdown in just

8634
07:18:23,430 --> 07:18:21,600
under two minutes and 30 seconds

8635
07:18:26,070 --> 07:18:23,440
we've already slowed the vehicle down to

8636
07:18:40,310 --> 07:18:26,080
about 16 miles an hour it's already less

8637
07:18:50,150 --> 07:18:43,270
main shoot decent rate nominal passing

8638
07:18:54,310 --> 07:18:51,910
so at this point dragon has saved all

8639
07:18:57,190 --> 07:18:54,320
propulsion systems

8640
07:19:03,590 --> 07:18:57,200
600 meters

8641
07:19:09,350 --> 07:19:06,070
should be approximately a minute 30 from

8642
07:19:13,030 --> 07:19:11,270
mission control team here in hawthorne

8643
07:19:15,590 --> 07:19:13,040
has reported the precise landing

8644
07:19:17,910 --> 07:19:15,600
coordinates to the recovery team

8645
07:19:37,590 --> 07:19:17,920
they are standing by

8646
07:19:47,350 --> 07:19:40,788
we just passed about 300 meters

8647
07:19:57,910 --> 07:19:49,350
200 meters

8648
07:20:05,990 --> 07:19:59,510
so there we heard bob and doug reporting

8649
07:20:10,868 --> 07:20:08,310
we should be able to see

8650
07:20:12,868 --> 07:20:10,878
the gulf of mexico here in the shot just

8651
07:20:15,510 --> 07:20:12,878
momentarily

8652
07:20:23,510 --> 07:20:15,520
as we're now just about 20 meters off

8653
07:20:27,750 --> 07:20:25,430
splashdown

8654
07:20:30,370 --> 07:20:27,760
as you can see on your screen we have

8655
07:20:38,868 --> 07:20:30,380
visual confirmation for splashdown

8656
07:20:43,750 --> 07:20:41,590
dragon endeavor has returned home

8657
07:20:46,070 --> 07:20:43,760
nasa astronauts bob and doug half of the

8658
07:20:47,670 --> 07:20:46,080
spacex and nasa teams welcome back to

8659
07:20:54,948 --> 07:20:47,680
planet earth and thanks for flying

8660
07:20:59,910 --> 07:20:57,030
it's truly our honor and privilege to

8661
07:21:00,830 --> 07:20:59,920
fly in flight of the crew dragon and

8662
07:21:07,990 --> 07:21:00,840
endeavor

8663
07:21:12,628 --> 07:21:11,510
all good and we're into section of four

8664
07:21:16,628 --> 07:21:12,638
decimal

8665
07:21:21,270 --> 07:21:18,468
thanks for those words doug and we uh

8666
07:21:23,350 --> 07:21:21,280
copy that you are into uh four decimal

8667
07:21:25,670 --> 07:21:23,360
eight zero zero

8668
07:21:28,628 --> 07:21:25,680
so great news all around there our space

8669
07:21:30,868 --> 07:21:28,638
dads are back on earth after a 19-hour

8670
07:21:33,190 --> 07:21:30,878
return journey from space

8671
07:21:35,510 --> 07:21:33,200
dragon endeavor has played splashdown in

8672
07:21:37,830 --> 07:21:35,520
the gulf of mexico just off the coast of

8673
07:21:40,150 --> 07:21:37,840
pensacola florida and on your screen

8674
07:21:42,150 --> 07:21:40,160
there you can see our two fast boats and

8675
07:21:45,270 --> 07:21:42,160
they are indeed fast

8676
07:21:48,070 --> 07:21:45,280
racing out to greet dragon endeavor as

8677
07:21:49,750 --> 07:21:48,080
uh it sits there the first

8678
07:21:51,830 --> 07:21:49,760
on there we can see a view inside the

8679
07:21:53,350 --> 07:21:51,840
capsule bob and doug looking good

8680
07:21:55,990 --> 07:21:53,360
although the communication was a little

8681
07:21:58,628 --> 07:21:56,000
choppy we did hear the endeavor in three

8682
07:22:01,830 --> 07:21:58,638
decimal one we show ourselves in stable

8683
07:22:06,788 --> 07:22:04,070
and spacex copies for uh vehicle

8684
07:22:09,110 --> 07:22:06,798
assessment step three decimal one stable

8685
07:22:11,110 --> 07:22:09,120
one good news

8686
07:22:13,190 --> 07:22:11,120
stable one essentially they're upright

8687
07:22:14,788 --> 07:22:13,200
in the water stable too

8688
07:22:16,310 --> 07:22:14,798
also another potential where it could be

8689
07:22:19,190 --> 07:22:16,320
on its side or even upside down the

8690
07:22:21,350 --> 07:22:19,200
dragon does have a water ballast system

8691
07:22:23,350 --> 07:22:21,360
to keep it upright where it's able to

8692
07:22:25,590 --> 07:22:23,360
essentially pump seawater

8693
07:22:27,910 --> 07:22:25,600
into bladders in the service section of

8694
07:22:30,388 --> 07:22:27,920
the capsule but they're upright we

8695
07:22:31,910 --> 07:22:30,398
already see the fast boats approaching

8696
07:22:34,070 --> 07:22:31,920
they touched down

8697
07:22:38,868 --> 07:22:34,080
came right on time

8698
07:22:40,708 --> 07:22:38,878
at 11 48 a.m pacific

8699
07:22:41,990 --> 07:22:40,718
1848

8700
07:22:43,590 --> 07:22:42,000
utc

8701
07:22:45,830 --> 07:22:43,600
bob and doug now in the water and the

8702
07:22:47,590 --> 07:22:45,840
recovery ops they've already begun we're

8703
07:22:49,110 --> 07:22:47,600
we already see the the fast boats

8704
07:22:50,388 --> 07:22:49,120
starting to move in

8705
07:22:52,948 --> 07:22:50,398
we're still maintaining that good

8706
07:22:55,510 --> 07:22:52,958
communication back with bob and doug and

8707
07:22:57,670 --> 07:22:55,520
the team here in hawthorne uh pretty

8708
07:22:59,990 --> 07:22:57,680
soon we should be getting uh the go for

8709
07:23:02,628 --> 07:23:00,000
them to move in begin their hyper golf

8710
07:23:05,270 --> 07:23:02,638
sniffs and uh begin wrangling up those

8711
07:23:08,868 --> 07:23:05,280
parachutes where we can see bob and doug

8712
07:23:10,468 --> 07:23:08,878
inside the capsule back on planet earth

8713
07:23:12,310 --> 07:23:10,478
yeah those fast boats will be moving in

8714
07:23:13,910 --> 07:23:12,320
to do a couple of things they'll be

8715
07:23:16,230 --> 07:23:13,920
performing what's known as a sniffer

8716
07:23:18,788 --> 07:23:16,240
test that's essentially to ensure that

8717
07:23:20,948 --> 07:23:18,798
the air around the vehicle doesn't have

8718
07:23:23,670 --> 07:23:20,958
any toxic fumes from the hypergolic

8719
07:23:25,590 --> 07:23:23,680
propellants on board so once we get the

8720
07:23:27,990 --> 07:23:25,600
all clear from there

8721
07:23:30,628 --> 07:23:28,000
the water recovery lead will give the

8722
07:23:32,388 --> 07:23:30,638
will give the go for approach and that's

8723
07:23:34,468 --> 07:23:32,398
when the the first fast boat will

8724
07:23:36,310 --> 07:23:34,478
actually approach the capsule hopefully

8725
07:23:37,750 --> 07:23:36,320
give a little wave to bob and doug

8726
07:23:40,310 --> 07:23:37,760
through the window

8727
07:23:41,990 --> 07:23:40,320
and uh one of the crew members will one

8728
07:23:45,750 --> 07:23:42,000
of the team members will actually climb

8729
07:23:47,910 --> 07:23:45,760
on top of crew dragon and begin to

8730
07:23:50,788 --> 07:23:47,920
begin to place the rigging equipment

8731
07:23:53,030 --> 07:23:50,798
necessary to hoist dragon out of the

8732
07:23:55,750 --> 07:23:53,040
water

8733
07:23:57,910 --> 07:23:55,760
i was still getting a view from the wb

8734
07:23:59,990 --> 07:23:57,920
uh the airplane flying overhead it gave

8735
07:24:02,070 --> 07:24:00,000
us those those great views of really our

8736
07:24:04,788 --> 07:24:02,080
first views of bob and doug re-entering

8737
07:24:07,590 --> 07:24:04,798
the earth's atmosphere from up above you

8738
07:24:10,150 --> 07:24:07,600
can see the four parachutes in the water

8739
07:24:13,350 --> 07:24:10,160
we heard those were cut automatically

8740
07:24:15,190 --> 07:24:13,360
as expected by dragon

8741
07:24:16,310 --> 07:24:15,200
so for now the crew just standing by

8742
07:24:18,708 --> 07:24:16,320
again they're going to stay in their

8743
07:24:21,350 --> 07:24:18,718
suits in their seats we're waiting for

8744
07:24:26,948 --> 07:24:21,360
all these initial checks dragon spacex

8745
07:24:29,430 --> 07:24:28,708
here

8746
07:24:39,190 --> 07:24:29,440
well

8747
07:24:42,548 --> 07:24:40,788
so essentially what just happened there

8748
07:24:44,310 --> 07:24:42,558
is they reconfigured solo if you can

8749
07:24:46,628 --> 07:24:44,320
just relay the

8750
07:24:49,110 --> 07:24:46,638
status of the

8751
07:24:52,070 --> 07:24:49,120
fast boats and the recovery as you get

8752
07:24:55,910 --> 07:24:52,080
them we would appreciate it

8753
07:24:58,788 --> 07:24:55,920
you bet absolutely doug uh wilco

8754
07:25:00,948 --> 07:24:58,798
so what just happened there you heard

8755
07:25:02,948 --> 07:25:00,958
comms reconfiguration that's essentially

8756
07:25:04,628 --> 07:25:02,958
looping bob and doug's communication

8757
07:25:07,110 --> 07:25:04,638
into the launch excuse me into the

8758
07:25:09,190 --> 07:25:07,120
recovery team uh so that if

8759
07:25:11,430 --> 07:25:09,200
they can hear feedback from bob and doug

8760
07:25:13,350 --> 07:25:11,440
directly as well now we talked a little

8761
07:25:15,510 --> 07:25:13,360
bit about

8762
07:25:18,708 --> 07:25:15,520
you can spacex ben and james know we're

8763
07:25:20,230 --> 07:25:18,718
doing pretty good so far

8764
07:25:21,910 --> 07:25:20,240
okay we'll let the flight dots know that

8765
07:25:24,070 --> 07:25:21,920
you're feeling good so far thanks for

8766
07:25:25,430 --> 07:25:24,080
that update

8767
07:25:26,868 --> 07:25:25,440
really good news there to hear that

8768
07:25:28,468 --> 07:25:26,878
they're feeling good

8769
07:25:30,310 --> 07:25:28,478
and they can let the flight surgeons

8770
07:25:33,430 --> 07:25:30,320
know that all is well inside dragon

8771
07:25:38,388 --> 07:25:35,750
all right and it sounds like we do have

8772
07:25:40,788 --> 07:25:38,398
uh one of our folks that's on location

8773
07:25:42,788 --> 07:25:40,798
there with the recovery forces nasa's

8774
07:25:44,948 --> 07:25:42,798
brandy dean she's been

8775
07:25:47,270 --> 07:25:44,958
she's uh joining us by satellite phone

8776
07:25:48,628 --> 07:25:47,280
brandie if you can hear me

8777
07:25:50,070 --> 07:25:48,638
i mean what is it like right there on

8778
07:25:51,750 --> 07:25:50,080
the water what was it like to watch

8779
07:25:54,230 --> 07:25:51,760
dragon career

8780
07:25:56,868 --> 07:25:54,240
watch them splash down for you yeah

8781
07:26:01,350 --> 07:25:56,878
best objective so stand by at the

8782
07:26:04,468 --> 07:26:03,110
okay spacex copies we'll be ready for

8783
07:26:06,150 --> 07:26:04,478
that in just a couple minutes we should

8784
07:26:10,350 --> 07:26:06,160
have the go for you in just a moment

8785
07:26:10,360 --> 07:26:20,868
[Music]

8786
07:26:20,878 --> 07:27:04,628
i think you're using purpose

8787
07:27:08,628 --> 07:27:06,628
there in the center of your screen

8788
07:27:11,430 --> 07:27:08,638
dragon capsule

8789
07:27:14,388 --> 07:27:11,440
waiting for the fast boats to approach

8790
07:27:15,910 --> 07:27:14,398
and begin the rigging process and there

8791
07:27:18,070 --> 07:27:15,920
on this left-hand side of your screen we

8792
07:27:21,590 --> 07:27:18,080
can see that second fast boat come into

8793
07:27:26,628 --> 07:27:24,468
dragon spacex we are go for recovery

8794
07:27:29,350 --> 07:27:26,638
personnel to approach expect personal

8795
07:27:34,150 --> 07:27:29,360
personnel aside alongside in just under

8796
07:27:39,670 --> 07:27:36,868
dragon copies thank you

8797
07:27:41,110 --> 07:27:39,680
all right so they're starting to move in

8798
07:27:42,948 --> 07:27:41,120
as kate just said that first boat's

8799
07:27:45,430 --> 07:27:42,958
going to go in sniff around the capsule

8800
07:27:46,948 --> 07:27:45,440
for any traces of hyper goals the second

8801
07:27:48,948 --> 07:27:46,958
one's going to start rounding up the

8802
07:27:51,990 --> 07:27:48,958
parachutes which we're getting some

8803
07:27:54,230 --> 07:27:52,000
really cool views from the wv57 still

8804
07:27:55,830 --> 07:27:54,240
flying overhead looking down you can see

8805
07:27:59,270 --> 07:27:55,840
the parachutes in the water and the

8806
07:28:00,948 --> 07:27:59,280
second boat start to gather them up

8807
07:28:03,030 --> 07:28:00,958
we'll try one more time real quick we

8808
07:28:05,510 --> 07:28:03,040
have nasa's brandy dean out with the

8809
07:28:07,190 --> 07:28:05,520
recovery forces randy if you can hear me

8810
07:28:11,350 --> 07:28:07,200
what was it like to watch this dragon

8811
07:28:14,830 --> 07:28:13,110
oh it was amazing i wish everybody could

8812
07:28:18,788 --> 07:28:14,840
have had my view

8813
07:28:20,628 --> 07:28:18,798
dude gorgeous day the water is calm

8814
07:28:23,270 --> 07:28:20,638
really the best weather we could have

8815
07:28:26,310 --> 07:28:23,280
asked for um and we did we heard the um

8816
07:28:28,628 --> 07:28:26,320
the sonic booms as it made its way back

8817
07:28:30,310 --> 07:28:28,638
we were able to find early on as the

8818
07:28:31,670 --> 07:28:30,320
parachutes were deployed it was very

8819
07:28:33,110 --> 07:28:31,680
exciting for everybody who was gathered

8820
07:28:35,030 --> 07:28:33,120
here

8821
07:28:36,868 --> 07:28:35,040
that's incredible we actually had some

8822
07:28:38,388 --> 07:28:36,878
questions from people if you'd be able

8823
07:28:39,750 --> 07:28:38,398
to hear the sonic boom and we weren't

8824
07:28:41,270 --> 07:28:39,760
sure so i'm really glad you just

8825
07:28:42,628 --> 07:28:41,280
answered that for us

8826
07:28:44,070 --> 07:28:42,638
um

8827
07:28:46,788 --> 07:28:44,080
i mean we talked so much about the

8828
07:28:48,628 --> 07:28:46,798
weather you said it looks great what

8829
07:28:50,868 --> 07:28:48,638
i mean what was it like on the ride out

8830
07:28:58,150 --> 07:28:50,878
there has it just been kind of clear

8831
07:29:01,190 --> 07:28:59,910
not sure if you can hear me right now um

8832
07:29:03,270 --> 07:29:01,200
but i think we're asking about the

8833
07:29:05,510 --> 07:29:03,280
weather whether it was clear skies there

8834
07:29:07,590 --> 07:29:05,520
are just a kind of a circle of clouds

8835
07:29:09,110 --> 07:29:07,600
along the horizon very low

8836
07:29:10,708 --> 07:29:09,120
but um

8837
07:29:16,548 --> 07:29:10,718
we were able to see the parachutes far

8838
07:29:20,230 --> 07:29:17,910
all right well

8839
07:29:22,230 --> 07:29:20,240
we're not getting any views on the boat

8840
07:29:23,670 --> 07:29:22,240
so what kind of activities taking place

8841
07:29:25,750 --> 07:29:23,680
right now we're able to see the fast

8842
07:29:27,350 --> 07:29:25,760
boats approaching the capsule

8843
07:29:31,910 --> 07:29:27,360
what's everybody doing on the boat to

8844
07:29:36,628 --> 07:29:34,310
uh the boat's also making its way

8845
07:29:37,750 --> 07:29:36,638
i can't see it with my

8846
07:29:39,990 --> 07:29:37,760
time here

8847
07:29:42,388 --> 07:29:40,000
but yeah so we're getting closer because

8848
07:29:44,230 --> 07:29:42,398
everybody's been kind of standing behind

8849
07:29:46,310 --> 07:29:44,240
them holding ready positions for quite a

8850
07:29:49,030 --> 07:29:46,320
while now so as soon as it it doesn't

8851
07:29:54,310 --> 07:29:49,040
fly the obvious religious extent of it

8852
07:29:58,388 --> 07:29:56,310
all right copy that well we're going to

8853
07:30:01,430 --> 07:29:58,398
keep watching from here

8854
07:30:02,788 --> 07:30:01,440
um thanks for calling in and thanks for

8855
07:30:04,948 --> 07:30:02,798
being out there with everybody and

8856
07:30:06,628 --> 07:30:04,958
getting us these great views it's really

8857
07:30:08,948 --> 07:30:06,638
incredible uh

8858
07:30:11,750 --> 07:30:08,958
thanks brandy you hope it gets you back

8859
07:30:18,468 --> 07:30:11,760
in port soon and we'll talk to you back

8860
07:30:22,230 --> 07:30:20,310
so there on your screen

8861
07:30:24,548 --> 07:30:22,240
oh camera view change that is a view

8862
07:30:25,990 --> 07:30:24,558
coming to us from go navigator the

8863
07:30:28,548 --> 07:30:26,000
recovery vessel

8864
07:30:31,190 --> 07:30:28,558
the two fast boats are out there getting

8865
07:30:34,230 --> 07:30:31,200
to getting ready to

8866
07:30:36,388 --> 07:30:34,240
basically plot excuse me

8867
07:30:39,910 --> 07:30:36,398
install the rigging equipment required

8868
07:30:42,150 --> 07:30:39,920
to hoist dragon out of the water

8869
07:30:43,990 --> 07:30:42,160
one the other fast boat is actually

8870
07:30:45,670 --> 07:30:44,000
collecting the parachutes from the water

8871
07:30:48,150 --> 07:30:45,680
we definitely want to

8872
07:30:48,948 --> 07:30:48,160
bring those back on board with us

8873
07:30:51,270 --> 07:30:48,958
but

8874
07:30:52,948 --> 07:30:51,280
shortly here we should actually see one

8875
07:30:55,670 --> 07:30:52,958
of the team members

8876
07:30:56,868 --> 07:30:55,680
crawl up onto the side of the capsule in

8877
07:30:58,548 --> 07:30:56,878
order to

8878
07:31:00,708 --> 07:30:58,558
install that

8879
07:31:03,430 --> 07:31:00,718
install the rigging like i mentioned

8880
07:31:05,750 --> 07:31:03,440
that particular team member is highly

8881
07:31:06,948 --> 07:31:05,760
experienced and highly trained as you

8882
07:31:09,670 --> 07:31:06,958
can imagine

8883
07:31:10,468 --> 07:31:09,680
climbing on top of an oddly shaped thing

8884
07:31:13,110 --> 07:31:10,478
in

8885
07:31:14,548 --> 07:31:13,120
you know the ocean it could be a little

8886
07:31:16,628 --> 07:31:14,558
tricky so

8887
07:31:18,948 --> 07:31:16,638
this person has undergone a lot hours

8888
07:31:21,510 --> 07:31:18,958
and hours of training and certification

8889
07:31:22,788 --> 07:31:21,520
in order to perform this very important

8890
07:31:25,190 --> 07:31:22,798
task there on the right hand side of

8891
07:31:26,388 --> 07:31:25,200
your screen we see the second fast boat

8892
07:31:28,948 --> 07:31:26,398
approaching

8893
07:31:31,430 --> 07:31:28,958
of course both of these boats

8894
07:31:34,230 --> 07:31:31,440
needed to wait for their queue

8895
07:31:36,548 --> 07:31:34,240
from the water recovery lead in order to

8896
07:31:37,990 --> 07:31:36,558
approach dragon after splashdown

8897
07:31:39,670 --> 07:31:38,000
again that was just to make sure that

8898
07:31:40,708 --> 07:31:39,680
there weren't any toxic vapors in the

8899
07:31:42,868 --> 07:31:40,718
air

8900
07:31:45,350 --> 07:31:42,878
and now that they got the all clear we

8901
07:31:48,070 --> 07:31:45,360
do see them beginning to work

8902
07:31:49,830 --> 07:31:48,080
on and around the dragon capsule

8903
07:31:50,868 --> 07:31:49,840
so even though the camera is a little

8904
07:31:54,310 --> 07:31:50,878
shaky

8905
07:31:56,388 --> 07:31:54,320
that water looks super super duper

8906
07:31:59,350 --> 07:31:56,398
smooth almost like glass which is

8907
07:32:00,788 --> 07:31:59,360
certainly ideal for a water recovery

8908
07:32:03,110 --> 07:32:00,798
like today

8909
07:32:05,110 --> 07:32:03,120
yeah got to remember that this is a view

8910
07:32:06,868 --> 07:32:05,120
from the the main recovery vessel which

8911
07:32:09,110 --> 07:32:06,878
was still a few miles away from the

8912
07:32:11,350 --> 07:32:09,120
splashdown spacex we have hyper crawl

8913
07:32:13,590 --> 07:32:11,360
sweeps and unfired ordinance checks

8914
07:32:15,990 --> 07:32:13,600
nominal rigor is on board the vehicle

8915
07:32:19,990 --> 07:32:16,000
about two five minutes until capsule

8916
07:32:23,990 --> 07:32:22,468
after that yeah we see him

8917
07:32:26,708 --> 07:32:24,000
outside and

8918
07:32:31,190 --> 07:32:29,350
all right confirmation there that all of

8919
07:32:34,310 --> 07:32:31,200
those hypergolic

8920
07:32:36,070 --> 07:32:34,320
uh vapor tests came out

8921
07:32:37,830 --> 07:32:36,080
positive or rather negative which is a

8922
07:32:40,468 --> 07:32:37,840
positive thing

8923
07:32:42,388 --> 07:32:40,478
so the team was able to approach and now

8924
07:32:44,708 --> 07:32:42,398
the crew member that is installing the

8925
07:32:46,230 --> 07:32:44,718
rigging is on top of the capsule it's

8926
07:32:48,948 --> 07:32:46,240
difficult to see there

8927
07:32:50,868 --> 07:32:48,958
because the slower vessel that the

8928
07:32:53,030 --> 07:32:50,878
primary recovery ship is a little

8929
07:32:55,270 --> 07:32:53,040
further away but as we heard it's just a

8930
07:33:00,070 --> 07:32:55,280
mere two and a half minutes until

8931
07:33:05,590 --> 07:33:01,670
i'm i'm sorry

8932
07:33:07,990 --> 07:33:05,600
25 minutes not 2.5 i misheard that yeah

8933
07:33:09,830 --> 07:33:08,000
they're fast but they're not that fast

8934
07:33:12,388 --> 07:33:09,840
we also have been hearing that uh the

8935
07:33:13,590 --> 07:33:12,398
secondary boat which its primary mission

8936
07:33:15,510 --> 07:33:13,600
in this case is securing those

8937
07:33:18,070 --> 07:33:15,520
parachutes uh they've already got buoys

8938
07:33:19,830 --> 07:33:18,080
attached to both droves and uh two of

8939
07:33:21,190 --> 07:33:19,840
the four mains nerdy had eyes on the

8940
07:33:23,270 --> 07:33:21,200
other two so they're moving through that

8941
07:33:24,948 --> 07:33:23,280
work pretty quickly again their primary

8942
07:33:27,590 --> 07:33:24,958
responsibility getting those parachutes

8943
07:33:29,670 --> 07:33:27,600
together the drogues

8944
07:33:31,430 --> 07:33:29,680
detaching from the spacecraft right

8945
07:33:33,430 --> 07:33:31,440
before the deployment of the mains the

8946
07:33:35,270 --> 07:33:33,440
mains automatically detaching

8947
07:33:36,548 --> 07:33:35,280
immediately as dragon detected

8948
07:33:38,708 --> 07:33:36,558
splashdown

8949
07:33:40,230 --> 07:33:38,718
all of that happening right per the

8950
07:33:42,310 --> 07:33:40,240
timeline

8951
07:33:45,030 --> 07:33:42,320
we've talked a little bit about the

8952
07:33:47,910 --> 07:33:45,040
hardwired buttons that bob and doug have

8953
07:33:50,628 --> 07:33:47,920
on their seats and in their control

8954
07:33:52,468 --> 07:33:50,638
displays and cutting the the main chutes

8955
07:33:54,150 --> 07:33:52,478
is one of those buttons in the event

8956
07:33:55,750 --> 07:33:54,160
that they weren't automatically cut

8957
07:33:56,948 --> 07:33:55,760
after splashdown bob and doug would have

8958
07:33:57,830 --> 07:33:56,958
had

8959
07:33:59,590 --> 07:33:57,840
the

8960
07:34:02,388 --> 07:33:59,600
ability to do so

8961
07:34:03,910 --> 07:34:02,398
if the winds were stronger and they

8962
07:34:05,990 --> 07:34:03,920
caught the parachutes it could certainly

8963
07:34:08,468 --> 07:34:06,000
create a condition where the capsule

8964
07:34:10,948 --> 07:34:08,478
could be moved unintentionally by those

8965
07:34:12,468 --> 07:34:10,958
dragging parachutes so definitely want

8966
07:34:14,388 --> 07:34:12,478
to avoid that so

8967
07:34:17,350 --> 07:34:14,398
that's one of the the few buttons that

8968
07:34:34,388 --> 07:34:17,360
are hardwired into the cabin for the

8969
07:34:37,910 --> 07:34:35,830
and again right now we're expecting

8970
07:34:40,230 --> 07:34:37,920
about 20 minutes

8971
07:34:42,868 --> 07:34:40,240
for the the main recovery vessel to go

8972
07:34:44,708 --> 07:34:42,878
navigator to reach dragon by that point

8973
07:34:46,628 --> 07:34:44,718
all the rigging will be affixed and then

8974
07:34:49,430 --> 07:34:46,638
they'll be able to use the a-frame

8975
07:34:51,350 --> 07:34:49,440
hydraulic lift on the back of the on the

8976
07:34:53,510 --> 07:34:51,360
back of the vessel to begin to pull

8977
07:34:55,510 --> 07:34:53,520
dragon up out of the water bob and dog

8978
07:34:57,190 --> 07:34:55,520
did report they're seeing the guys

8979
07:35:00,310 --> 07:34:57,200
climbing around outside their window on

8980
07:35:02,548 --> 07:35:00,320
the capsule getting that rigging affixed

8981
07:35:03,590 --> 07:35:02,558
still doing good uh from all of their

8982
07:35:04,948 --> 07:35:03,600
reports

8983
07:35:07,030 --> 07:35:04,958
and we're just going to see the vessel

8984
07:35:09,990 --> 07:35:07,040
continue to close in it's a little over

8985
07:35:11,750 --> 07:35:10,000
1.3 nautical miles still away but you

8986
07:35:14,788 --> 07:35:11,760
can see things starting to sharpen up in

8987
07:35:16,948 --> 07:35:14,798
our view as it does draw closer

8988
07:35:19,190 --> 07:35:16,958
one thing i didn't get to mention as the

8989
07:35:21,590 --> 07:35:19,200
sequence events was happening everything

8990
07:35:22,468 --> 07:35:21,600
was going so quickly uh just before the

8991
07:35:24,310 --> 07:35:22,478
drogue

8992
07:35:27,030 --> 07:35:24,320
deployment the seats automatically

8993
07:35:29,830 --> 07:35:27,040
rotated to about 26 degrees

8994
07:35:31,910 --> 07:35:29,840
and so if you think back to when we saw

8995
07:35:34,788 --> 07:35:31,920
bob and doug while they were still on

8996
07:35:37,110 --> 07:35:34,798
orbit and during the

8997
07:35:39,750 --> 07:35:37,120
the deorbit burn and all their departure

8998
07:35:41,910 --> 07:35:39,760
burns they were actually laying closer

8999
07:35:43,190 --> 07:35:41,920
to on their backs at the 40 degree

9000
07:35:45,670 --> 07:35:43,200
position

9001
07:35:47,990 --> 07:35:45,680
where essentially they were looking up

9002
07:35:49,670 --> 07:35:48,000
at the top of dragon capsule like their

9003
07:35:52,150 --> 07:35:49,680
stomachs were facing

9004
07:35:53,670 --> 07:35:52,160
the top nose cone there at this point

9005
07:35:54,948 --> 07:35:53,680
the seats would have rotated so they're

9006
07:35:56,310 --> 07:35:54,958
in a little bit more of an upright

9007
07:35:59,910 --> 07:35:56,320
position

9008
07:36:02,868 --> 07:35:59,920
that's done to ensure that um the loads

9009
07:36:06,708 --> 07:36:02,878
experienced from landing are you know

9010
07:36:08,708 --> 07:36:06,718
don't doesn't doesn't hurt them so uh at

9011
07:36:10,310 --> 07:36:08,718
this point they are not really laying on

9012
07:36:11,830 --> 07:36:10,320
their backs in the ocean they are seated

9013
07:36:14,310 --> 07:36:11,840
upright a little bit which would allow

9014
07:36:16,788 --> 07:36:14,320
them to have a better view

9015
07:36:34,548 --> 07:36:16,798
of the team working to

9016
07:36:39,350 --> 07:36:37,030
so at this point we're at about 22

9017
07:36:53,750 --> 07:36:39,360
minutes until dragon will be lifted onto

9018
07:36:57,670 --> 07:36:55,430
bob and doug are still strapped into

9019
07:36:59,430 --> 07:36:57,680
their seats

9020
07:37:00,230 --> 07:36:59,440
kind of like an airplane you know they

9021
07:37:03,270 --> 07:37:00,240
say

9022
07:37:04,948 --> 07:37:03,280
do not unbuckle your seat belt until the

9023
07:37:07,350 --> 07:37:04,958
captain determines that it's safe to do

9024
07:37:12,468 --> 07:37:09,030
they will stay remain in their seats

9025
07:37:14,628 --> 07:37:12,478
throughout the entire recovery process

9026
07:37:28,388 --> 07:37:14,638
essentially until it's time to get them

9027
07:37:33,110 --> 07:37:30,230
like i said we are expecting to lift

9028
07:37:33,990 --> 07:37:33,120
dragon onto the go navigator recovery

9029
07:37:38,070 --> 07:37:34,000
ship

9030
07:37:43,030 --> 07:37:40,548
and then in 28 minutes we will be

9031
07:37:46,150 --> 07:37:43,040
opening that hatch

9032
07:37:50,230 --> 07:37:46,160
and beginning crew egress

9033
07:37:53,670 --> 07:37:51,830
and we did hear the rigging is pretty

9034
07:37:56,310 --> 07:37:53,680
much complete so

9035
07:37:58,310 --> 07:37:56,320
right as they arrive there at the

9036
07:37:59,510 --> 07:37:58,320
capsule the main recovery vessel will be

9037
07:38:08,150 --> 07:37:59,520
able to begin

9038
07:38:12,628 --> 07:38:09,830
so now as the recovery vessel go

9039
07:38:14,708 --> 07:38:12,638
navigator is getting closer to dragon

9040
07:38:16,868 --> 07:38:14,718
dragon's position there off the coast of

9041
07:38:21,350 --> 07:38:16,878
pensacola florida we're able to see

9042
07:38:25,430 --> 07:38:24,388
it is certainly no longer

9043
07:38:44,628 --> 07:38:25,440
a

9044
07:38:47,510 --> 07:38:44,638
the

9045
07:38:50,708 --> 07:38:47,520
internal temperature

9046
07:38:55,350 --> 07:38:53,110
and you are seeing a few more boats than

9047
07:38:57,590 --> 07:38:55,360
expected um

9048
07:39:00,948 --> 07:38:57,600
the team's currently working

9049
07:39:48,150 --> 07:39:00,958
with a few private vessels in the area

9050
07:40:10,230 --> 07:39:50,070
and now we see one of the spacex fast

9051
07:40:15,270 --> 07:40:13,110
so we are being advised that uh the

9052
07:40:17,670 --> 07:40:15,280
recovery team is radioing out to the

9053
07:40:20,548 --> 07:40:17,680
vessels in the water near crew dragon to

9054
07:40:22,868 --> 07:40:20,558
vacate the area uh so that we're able to

9055
07:40:25,030 --> 07:40:22,878
extract bob and doug safely

9056
07:40:27,030 --> 07:40:25,040
you know also for the safety of those

9057
07:40:28,310 --> 07:40:27,040
folks in the area as well not just bob

9058
07:40:30,948 --> 07:40:28,320
and doug

9059
07:40:32,388 --> 07:40:30,958
yeah this is this is obviously a dynamic

9060
07:40:34,230 --> 07:40:32,398
operation

9061
07:40:36,628 --> 07:40:34,240
one of the first things we do is make

9062
07:40:39,110 --> 07:40:36,638
sure there aren't essentially poisonous

9063
07:40:42,230 --> 07:40:39,120
fumes around the capsule so

9064
07:40:44,150 --> 07:40:42,240
something like this just

9065
07:40:45,830 --> 07:40:44,160
really can endanger the whole thing

9066
07:40:48,230 --> 07:40:45,840
endanger the crew members and endanger

9067
07:40:50,788 --> 07:40:48,240
themselves so the spacex team's moving

9068
07:40:53,190 --> 07:40:50,798
in to try and get them away so they can

9069
07:40:55,510 --> 07:40:53,200
safely recover the dragon capsule and

9070
07:40:58,230 --> 07:40:55,520
get bob and doug on deck and safely

9071
07:41:00,468 --> 07:40:58,240
inside their medical quarters so we can

9072
07:41:01,430 --> 07:41:00,478
see them they're getting a lot closer we

9073
07:41:03,110 --> 07:41:01,440
expect

9074
07:41:04,548 --> 07:41:03,120
about 10 minutes or so until they should

9075
07:41:06,230 --> 07:41:04,558
be in position

9076
07:41:08,708 --> 07:41:06,240
all the rigging has been affixed on the

9077
07:41:10,230 --> 07:41:08,718
dragon capsule and once they arrive

9078
07:41:12,948 --> 07:41:10,240
they'll be able to use that hydraulic

9079
07:41:22,628 --> 07:41:12,958
lift to get dragon up and out of the

9080
07:41:27,590 --> 07:41:24,708
so the recovery vessel go navigator is

9081
07:41:30,388 --> 07:41:27,600
getting closer and closer to dragon

9082
07:41:30,398 --> 07:41:33,750
as it awaits

9083
07:41:37,910 --> 07:41:35,270
its recovery

9084
07:41:40,150 --> 07:41:37,920
as it awaits to be hoisted out of the

9085
07:41:44,788 --> 07:41:40,160
gulf of mexico again we landed just off

9086
07:41:49,750 --> 07:41:46,788
maybe next time we shouldn't announce

9087
07:41:51,990 --> 07:41:49,760
our landing zone

9088
07:41:53,190 --> 07:41:52,000
oh there we got a shot from our wb-57

9089
07:41:55,190 --> 07:41:53,200
plane it looks like that area has

9090
07:42:03,990 --> 07:41:55,200
cleared out significantly so that is

9091
07:42:08,628 --> 07:42:06,548
and we're also hearing that all of the

9092
07:42:09,910 --> 07:42:08,638
parachutes have buoys on them so also

9093
07:42:12,708 --> 07:42:09,920
good news

9094
07:42:21,430 --> 07:42:12,718
as the recovery process continues

9095
07:42:21,440 --> 07:42:27,670
dragon spacex for comrade config

9096
07:42:30,868 --> 07:42:29,270
go ahead mike

9097
07:42:33,190 --> 07:42:30,878
hey doug we're about to reconfigure the

9098
07:42:35,030 --> 07:42:33,200
forward link we may lose that for about

9099
07:42:39,190 --> 07:42:35,040
one or so minutes and that should happen

9100
07:42:42,388 --> 07:42:40,468
let's give this call back when you think

9101
07:43:01,670 --> 07:42:42,398
you got it back

9102
07:43:05,190 --> 07:43:03,750
so as the main vessel gets closer it's

9103
07:43:07,670 --> 07:43:05,200
going to back up

9104
07:43:09,270 --> 07:43:07,680
and get its hydraulic lift set up right

9105
07:43:10,150 --> 07:43:09,280
next to the dragon capsule still in the

9106
07:43:12,548 --> 07:43:10,160
water

9107
07:43:14,468 --> 07:43:12,558
bob and doug's still inside just waiting

9108
07:43:16,628 --> 07:43:14,478
for that recovery we should start the

9109
07:43:18,070 --> 07:43:16,638
hoisting operations in the next 10 to 15

9110
07:43:20,628 --> 07:43:18,080
minutes

9111
07:43:22,310 --> 07:43:20,638
and then it'll be a pretty quick lift up

9112
07:43:24,788 --> 07:43:22,320
out of the water using that hydraulic

9113
07:43:27,190 --> 07:43:24,798
lift into the dragon nest on the deck of

9114
07:43:29,430 --> 07:43:27,200
the boat or the ship rather and then

9115
07:43:31,590 --> 07:43:29,440
they'll move it underneath the helipad

9116
07:43:33,110 --> 07:43:31,600
into essentially the crew recovery area

9117
07:43:34,868 --> 07:43:33,120
where they'll have a platform right up

9118
07:43:35,910 --> 07:43:34,878
to the hatch they'll be able to open up

9119
07:43:37,270 --> 07:43:35,920
the hatch

9120
07:43:38,708 --> 07:43:37,280
spacex

9121
07:43:40,468 --> 07:43:38,718
medical doctor will be the first one

9122
07:43:42,388 --> 07:43:40,478
through the door able to do a quick

9123
07:43:45,670 --> 07:43:42,398
check in with bob and doug on their

9124
07:43:48,070 --> 07:43:45,680
status and then he and the other

9125
07:43:49,510 --> 07:43:48,080
medical doctors flight surgeons and

9126
07:43:52,070 --> 07:43:49,520
trained technicians will begin to help

9127
07:43:53,910 --> 07:43:52,080
them out of the capsule

9128
07:43:55,990 --> 07:43:53,920
yeah earlier just after splashdown we

9129
07:43:58,788 --> 07:43:56,000
did hear uh bob and doug report that

9130
07:44:00,868 --> 07:43:58,798
they were feeling good after re-entry so

9131
07:44:04,468 --> 07:44:00,878
that was relayed to the flight surgeon

9132
07:44:06,350 --> 07:44:04,478
and good news to hear

9133
07:44:08,388 --> 07:44:06,360
again this is a view coming from the

9134
07:44:10,548 --> 07:44:08,398
wb-57 plane

9135
07:44:12,150 --> 07:44:10,558
as it is circling the area

9136
07:44:13,750 --> 07:44:12,160
and we can see

9137
07:44:19,350 --> 07:44:13,760
dragon

9138
07:44:26,070 --> 07:44:23,030
again we are anticipating that lift

9139
07:44:28,788 --> 07:44:26,080
to begin in just under 15 minutes we're

9140
07:44:30,230 --> 07:44:28,798
approaching 14 minutes here

9141
07:44:32,070 --> 07:44:30,240
and then

9142
07:44:33,270 --> 07:44:32,080
in 21 minutes

9143
07:44:35,670 --> 07:44:33,280
we will have

9144
07:44:37,590 --> 07:44:35,680
an open hatch

9145
07:44:40,070 --> 07:44:37,600
you can see the main recovery vessel in

9146
07:44:43,430 --> 07:44:40,080
the top right there that's the helipad

9147
07:44:46,788 --> 07:44:43,440
with the big spacex on top it's now

9148
07:44:48,948 --> 07:44:46,798
backing up towards the capsule

9149
07:44:51,430 --> 07:44:48,958
certainly not to be confused with one of

9150
07:44:58,468 --> 07:44:51,440
our

9151
07:45:03,190 --> 07:45:01,990
there's a live view of dragon of dragon

9152
07:45:07,110 --> 07:45:03,200
floating in the water there in the

9153
07:45:08,708 --> 07:45:07,120
background along with many onlookers

9154
07:45:09,590 --> 07:45:08,718
certainly from a safer distance at this

9155
07:45:12,150 --> 07:45:09,600
point

9156
07:45:14,468 --> 07:45:12,160
this is a live shot coming from go

9157
07:45:16,708 --> 07:45:14,478
navigator our primary recovery vessel

9158
07:45:18,708 --> 07:45:16,718
here so it's dr crew dragon is also

9159
07:45:21,350 --> 07:45:18,718
accompanied by the fast boats that are

9160
07:45:22,948 --> 07:45:21,360
helping to bring it in closer

9161
07:45:25,910 --> 07:45:22,958
and there you can see a couple of the

9162
07:45:27,830 --> 07:45:25,920
recovery team members on the deck

9163
07:45:31,110 --> 07:45:27,840
and also just behind them we get our

9164
07:45:33,190 --> 07:45:31,120
first good view of the nest uh yes so

9165
07:45:34,868 --> 07:45:33,200
this is uh essentially the nest in the

9166
07:45:36,868 --> 07:45:34,878
background there dragon will be hoisted

9167
07:45:39,510 --> 07:45:36,878
using the hydraulic lift out of the

9168
07:45:41,590 --> 07:45:39,520
water and into that nest that nest will

9169
07:45:43,670 --> 07:45:41,600
then be pulled towards the camera from

9170
07:45:45,430 --> 07:45:43,680
this view towards those individuals on

9171
07:45:47,110 --> 07:45:45,440
that upper deck there

9172
07:45:52,070 --> 07:45:47,120
and that's where the

9173
07:45:56,788 --> 07:45:54,868
loud and clear solo us

9174
07:45:58,628 --> 07:45:56,798
loud and clear as well and from the

9175
07:46:00,708 --> 07:45:58,638
video looks like the boat is about one

9176
07:46:04,868 --> 07:46:00,718
uh length away about five to ten meters

9177
07:46:10,388 --> 07:46:06,920
copy that uh thanks for the update

9178
07:46:13,510 --> 07:46:11,590
all right so good news there we're

9179
07:46:14,388 --> 07:46:13,520
getting ready to see dragon to be lifted

9180
07:46:17,350 --> 07:46:14,398
out of the water

9181
07:46:18,948 --> 07:46:17,360
and into the recovery nest

9182
07:46:20,468 --> 07:46:18,958
as i was saying that nest will be pulled

9183
07:46:21,910 --> 07:46:20,478
towards the camera

9184
07:46:23,750 --> 07:46:21,920
towards the upper deck that we saw there

9185
07:46:26,388 --> 07:46:23,760
and that's where the medical stretchers

9186
07:46:29,270 --> 07:46:26,398
will be waiting uh to assist them into

9187
07:46:32,310 --> 07:46:29,280
the medical base for evaluation after

9188
07:46:37,110 --> 07:46:34,868
it's already been it's already been 25

9189
07:46:39,030 --> 07:46:37,120
minutes since they splashed down it

9190
07:46:41,270 --> 07:46:39,040
doesn't feel like it that was definitely

9191
07:46:43,270 --> 07:46:41,280
the fastest 25 minutes of the day the

9192
07:46:44,948 --> 07:46:43,280
the timeline we were anticipating was

9193
07:46:46,708 --> 07:46:44,958
for the lifting operations to start

9194
07:46:48,548 --> 07:46:46,718
within about 30 minutes so we're pretty

9195
07:46:50,388 --> 07:46:48,558
much right on the timeline still that's

9196
07:46:53,430 --> 07:46:50,398
been a

9197
07:46:55,350 --> 07:46:53,440
a pretty common thing so far today

9198
07:46:57,670 --> 07:46:55,360
you can see them with one of the fast

9199
07:47:00,628 --> 07:46:57,680
boats getting it positioned to start

9200
07:47:02,388 --> 07:47:00,638
moving out with the additional rigging

9201
07:47:04,310 --> 07:47:02,398
to affix to the dragon capsule where

9202
07:47:05,830 --> 07:47:04,320
they're going to use this a-frame to

9203
07:47:07,670 --> 07:47:05,840
pull it up out of the water and you can

9204
07:47:10,548 --> 07:47:07,680
see the dragon nest at the very bottom

9205
07:47:14,868 --> 07:47:10,558
it's that circular object with the a1

9206
07:47:19,190 --> 07:47:17,030
so while this is the first time we are

9207
07:47:21,830 --> 07:47:19,200
recovering a capsule with crew members

9208
07:47:23,270 --> 07:47:21,840
on board the recovery team has been

9209
07:47:25,430 --> 07:47:23,280
dragging just letting you know we got a

9210
07:47:29,910 --> 07:47:25,440
couple lines connected and rigging is in

9211
07:47:33,990 --> 07:47:31,830
thank you

9212
07:47:36,468 --> 07:47:34,000
all right there so just updating the

9213
07:47:38,628 --> 07:47:36,478
crew that they might feel some

9214
07:47:41,110 --> 07:47:38,638
momentum as the lines as a couple of the

9215
07:47:42,708 --> 07:47:41,120
rigging lines are attached

9216
07:47:45,350 --> 07:47:42,718
there we can actually there's our first

9217
07:47:47,670 --> 07:47:45,360
good shot of the individual who is

9218
07:47:49,430 --> 07:47:47,680
placing that rigging equipment equipment

9219
07:47:51,350 --> 07:47:49,440
again that's someone that's highly

9220
07:47:53,110 --> 07:47:51,360
specialized and very well trained for

9221
07:47:54,708 --> 07:47:53,120
these operations

9222
07:47:56,788 --> 07:47:54,718
as i was saying the recovery team has

9223
07:47:58,948 --> 07:47:56,798
rehearsed and practiced this with bob

9224
07:48:01,750 --> 07:47:58,958
and doug themselves actually

9225
07:48:04,230 --> 07:48:01,760
in a test capsule practicing the the

9226
07:48:05,990 --> 07:48:04,240
egress as well as

9227
07:48:08,230 --> 07:48:06,000
they have recovered excuse me they have

9228
07:48:09,110 --> 07:48:08,240
practiced the recovery process many

9229
07:48:10,628 --> 07:48:09,120
times

9230
07:48:12,948 --> 07:48:10,638
and actually

9231
07:48:14,388 --> 07:48:12,958
through those practice runs they have

9232
07:48:17,670 --> 07:48:14,398
effectively

9233
07:48:20,708 --> 07:48:17,680
cut the recovery period in half from the

9234
07:48:22,868 --> 07:48:20,718
initial demo one mission so

9235
07:48:25,110 --> 07:48:22,878
it's really nice to see that

9236
07:48:27,990 --> 07:48:25,120
the the process itself after being

9237
07:48:31,430 --> 07:48:28,000
rehearsed and carefully choreographed

9238
07:48:33,910 --> 07:48:31,440
is is going super efficiently again

9239
07:48:35,990 --> 07:48:33,920
safety is the number one priority so

9240
07:48:38,310 --> 07:48:36,000
making sure that only

9241
07:48:40,708 --> 07:48:38,320
personnel involved in active recovery

9242
07:48:42,150 --> 07:48:40,718
operations are present on the deck

9243
07:48:44,310 --> 07:48:42,160
you may have heard us mention before

9244
07:48:46,868 --> 07:48:44,320
that there are about 40 people on board

9245
07:48:49,590 --> 07:48:46,878
today but we certainly don't want anyone

9246
07:48:53,430 --> 07:48:49,600
in danger or to fall

9247
07:49:00,788 --> 07:48:55,510
that guy intentionally jumped

9248
07:49:05,110 --> 07:49:02,948
we're ready thank you

9249
07:49:07,670 --> 07:49:05,120
all right so the crew was just told in

9250
07:49:08,948 --> 07:49:07,680
about 30 in the next 30 seconds they

9251
07:49:11,030 --> 07:49:08,958
have the lines to fix so they're going

9252
07:49:12,548 --> 07:49:11,040
to start lifting the capsule up out of

9253
07:49:13,750 --> 07:49:12,558
the water

9254
07:49:15,990 --> 07:49:13,760
and at this point the communication

9255
07:49:17,750 --> 07:49:16,000
we're getting with dragon is actually

9256
07:49:19,110 --> 07:49:17,760
being routed through the boat itself at

9257
07:49:23,750 --> 07:49:19,120
this point

9258
07:49:29,110 --> 07:49:26,948
the dragon is out of the water yeah so

9259
07:49:30,948 --> 07:49:29,120
now a frame is going to start swinging

9260
07:49:32,948 --> 07:49:30,958
it back

9261
07:49:45,430 --> 07:49:32,958
and it's bound right for that nest at

9262
07:49:49,350 --> 07:49:47,110
so we're getting a better shot of all

9263
07:49:51,270 --> 07:49:49,360
the points in which dragon is tethered

9264
07:50:14,150 --> 07:49:51,280
to the hydraulic lift ensuring that it

9265
07:50:18,150 --> 07:50:16,230
there we can see dragon endeavor being

9266
07:50:21,830 --> 07:50:18,160
carefully set down into the recovery

9267
07:50:23,750 --> 07:50:21,840
nest on top of go navigator

9268
07:50:25,990 --> 07:50:23,760
dragon spacex welcome aboard the

9269
07:50:27,910 --> 07:50:26,000
recovery vessel recovery personnel are

9270
07:50:33,110 --> 07:50:27,920
completing final checks and preparing to

9271
07:50:33,120 --> 07:50:36,548
very happy thank you

9272
07:50:42,150 --> 07:50:39,430
so for the first time in two months nasa

9273
07:50:44,708 --> 07:50:42,160
astronauts bob benkin and doug hurley

9274
07:50:46,708 --> 07:50:44,718
are on some sort of ground yes we can't

9275
07:50:49,190 --> 07:50:46,718
call it solid ground because it is a

9276
07:50:50,548 --> 07:50:49,200
ship however uh it is the first time

9277
07:50:53,510 --> 07:50:50,558
that they are not

9278
07:50:57,990 --> 07:50:53,520
in space uh on a rocket or bobbing in

9279
07:51:02,468 --> 07:50:59,830
so now that they're in the nest they're

9280
07:51:04,310 --> 07:51:02,478
going to start translating it forward

9281
07:51:05,750 --> 07:51:04,320
and dragon's going to move into

9282
07:51:08,070 --> 07:51:05,760
essentially the hanger section

9283
07:51:09,750 --> 07:51:08,080
underneath that helipad and then up to

9284
07:51:12,948 --> 07:51:09,760
that recovery platform that we saw a

9285
07:51:16,070 --> 07:51:14,788
at that point

9286
07:51:17,990 --> 07:51:16,080
the

9287
07:51:19,750 --> 07:51:18,000
spacecraft technicians will work to open

9288
07:51:21,590 --> 07:51:19,760
up the hatch as we said previously it's

9289
07:51:23,910 --> 07:51:21,600
a manual process with a couple of

9290
07:51:27,590 --> 07:51:25,510
attachments you have to engage before

9291
07:51:28,708 --> 07:51:27,600
the hatch itself can be open they'll get

9292
07:51:29,990 --> 07:51:28,718
it opened

9293
07:51:32,468 --> 07:51:30,000
and then

9294
07:51:34,708 --> 07:51:32,478
spacex's neil menon will be the first

9295
07:51:36,868 --> 07:51:34,718
one through the hatchway to check in on

9296
07:51:38,948 --> 07:51:36,878
bob and doug get their initial health

9297
07:51:40,708 --> 07:51:38,958
assessment see if they're ready to move

9298
07:51:42,628 --> 07:51:40,718
and then we'll start assisting them out

9299
07:51:56,388 --> 07:51:42,638
of the capsule and into that medical

9300
07:51:59,350 --> 07:51:58,468
so at this point the recovery team is

9301
07:52:02,310 --> 07:51:59,360
doing

9302
07:52:05,750 --> 07:52:02,320
uh final securing of the capsule

9303
07:52:08,788 --> 07:52:05,760
in preparation to actually move the

9304
07:52:11,350 --> 07:52:08,798
recovery nest uh into closer to the

9305
07:52:13,350 --> 07:52:11,360
interior of the ship it'll actually be

9306
07:52:16,150 --> 07:52:13,360
in a little bit of a covered deck there

9307
07:52:18,150 --> 07:52:16,160
we had we saw that camera view earlier

9308
07:52:21,030 --> 07:52:18,160
looking straight out from the center of

9309
07:52:23,830 --> 07:52:21,040
the boat so once dragon is secured in

9310
07:52:26,388 --> 07:52:23,840
the nest uh the nest will be translated

9311
07:52:28,708 --> 07:52:26,398
then forward and uh closer to the

9312
07:52:30,628 --> 07:52:28,718
recovery

9313
07:52:32,150 --> 07:52:30,638
excuse me closer to the position in

9314
07:52:33,030 --> 07:52:32,160
which we're able to actually open the

9315
07:52:35,750 --> 07:52:33,040
hatch

9316
07:52:38,628 --> 07:52:35,760
so while dragon is on board safely uh

9317
07:52:40,070 --> 07:52:38,638
we're not able to do that just yet

9318
07:52:41,270 --> 07:52:40,080
yeah they're they're

9319
07:52:42,868 --> 07:52:41,280
working to

9320
07:52:45,510 --> 07:52:42,878
detach some of those lines that were

9321
07:52:47,350 --> 07:52:45,520
used to hoist it using the a-frame and

9322
07:52:49,030 --> 07:52:47,360
we heard that they should be done with

9323
07:53:09,030 --> 07:52:49,040
that in just a moment and then we'll

9324
07:53:12,150 --> 07:53:10,788
so right now we can see the recovery

9325
07:53:15,750 --> 07:53:12,160
team

9326
07:53:18,388 --> 07:53:15,760
releasing those securing lines that were

9327
07:53:20,788 --> 07:53:18,398
used during the lift

9328
07:53:21,750 --> 07:53:20,798
of the capsule from the water

9329
07:53:23,750 --> 07:53:21,760
into

9330
07:53:25,590 --> 07:53:23,760
the nest

9331
07:53:27,830 --> 07:53:25,600
so they are releasing those securing

9332
07:53:41,350 --> 07:53:27,840
lines from the sides making sure it is

9333
07:53:46,150 --> 07:53:44,628
and there we see dragon moving forward

9334
07:53:52,468 --> 07:53:46,160
look at that

9335
07:53:56,310 --> 07:53:53,990
it's really interesting to see those

9336
07:54:04,150 --> 07:53:56,320
scorching marks now that we get a really

9337
07:54:08,628 --> 07:54:06,388
standing by for the go for side hatch

9338
07:54:11,670 --> 07:54:08,638
open

9339
07:54:14,230 --> 07:54:11,680
that rounded square there in the center

9340
07:54:16,388 --> 07:54:14,240
of the capsule is that side hatch

9341
07:54:19,670 --> 07:54:16,398
and on either side are those oval

9342
07:54:27,030 --> 07:54:22,548
dragon spacex standby for side hatch

9343
07:54:30,310 --> 07:54:28,468
happy we're ready

9344
07:54:42,948 --> 07:54:30,320
all right crew got the call we're go for

9345
07:54:42,958 --> 07:54:58,150
so

9346
07:55:01,590 --> 07:54:59,750
and if you look closely immediately

9347
07:55:02,868 --> 07:55:01,600
above the hatch you can see the area

9348
07:55:04,388 --> 07:55:02,878
where you can see them working in now

9349
07:55:07,270 --> 07:55:04,398
that's where those drogue shoots

9350
07:55:09,510 --> 07:55:07,280
deployed from the two circles on either

9351
07:55:12,150 --> 07:55:09,520
side were where the mortars were

9352
07:55:13,270 --> 07:55:12,160
the main parachutes now hidden by the

9353
07:55:24,548 --> 07:55:13,280
platform

9354
07:55:31,590 --> 07:55:27,190
so the crew is in the process of

9355
07:55:36,708 --> 07:55:34,310
we can see that go navigator is in

9356
07:55:41,030 --> 07:55:36,718
transit it is making its way back to the

9357
07:56:19,270 --> 07:55:43,830
however bob and doug will get a ride

9358
07:56:22,230 --> 07:56:21,030
so again we're preparing to open the

9359
07:56:24,388 --> 07:56:22,240
side hatch

9360
07:56:26,628 --> 07:56:24,398
and once that done once that is done the

9361
07:56:27,510 --> 07:56:26,638
flight surgeon

9362
07:56:29,670 --> 07:56:27,520
will

9363
07:56:31,030 --> 07:56:29,680
pop his head in do an initial

9364
07:56:33,590 --> 07:56:31,040
check

9365
07:56:35,670 --> 07:56:33,600
see how bob and doug are doing

9366
07:56:38,388 --> 07:56:35,680
and dragon spacex we got a slight delay

9367
07:56:50,548 --> 07:56:38,398
due to some potential ndo hits near the

9368
07:56:54,310 --> 07:56:52,310
and so they're still continuing to do

9369
07:56:57,430 --> 07:56:54,320
kind of those sniffs so checking for any

9370
07:56:59,990 --> 07:56:57,440
vapors or anything so those ndo it's no2

9371
07:57:01,750 --> 07:57:00,000
nitrogen dioxide

9372
07:57:03,910 --> 07:57:01,760
primarily can

9373
07:57:06,628 --> 07:57:03,920
get detected in the air from the burning

9374
07:57:08,548 --> 07:57:06,638
of fuel so they're going to continue to

9375
07:57:10,868 --> 07:57:08,558
just inspect around the capsule make

9376
07:57:13,190 --> 07:57:10,878
sure that it's again safe for the crew

9377
07:57:16,788 --> 07:57:13,200
safe for the recovery experts before

9378
07:57:20,628 --> 07:57:18,468
but again moving right along the

9379
07:57:26,150 --> 07:57:20,638
timeline it's

9380
07:57:26,160 --> 07:57:37,110
am pacific

9381
07:57:40,468 --> 07:57:38,788
and so again they're just pausing the

9382
07:57:43,750 --> 07:57:40,478
operations for a moment

9383
07:57:47,030 --> 07:57:43,760
doing some additional air sampling

9384
07:57:49,350 --> 07:57:47,040
around the prop system we still have

9385
07:57:51,030 --> 07:57:49,360
telemetry being fed from the vehicle so

9386
07:57:54,070 --> 07:57:51,040
flight controllers here

9387
07:57:56,468 --> 07:57:54,080
in hawthorne able to monitor prop tanks

9388
07:58:14,708 --> 07:57:56,478
propulsion tank pressures and not seeing

9389
07:58:45,990 --> 07:58:41,350
so

9390
07:58:48,150 --> 07:58:46,000
in the operations is again they're just

9391
07:58:51,030 --> 07:58:48,160
sniffing around the capsule

9392
07:58:52,548 --> 07:58:51,040
making sure we don't have any readings

9393
07:58:54,868 --> 07:58:52,558
that might indicate a fuel leak or

9394
07:58:57,190 --> 07:58:54,878
anything around the vehicle

9395
07:58:59,510 --> 07:58:57,200
they did detect some ndos and nitrogen

9396
07:59:02,468 --> 07:58:59,520
dioxide which is typically a residue

9397
07:59:03,990 --> 07:59:02,478
that arises from the burning of fuel so

9398
07:59:06,230 --> 07:59:04,000
they're continuing to do just a couple

9399
07:59:07,590 --> 07:59:06,240
of different air readings grab samples

9400
07:59:09,190 --> 07:59:07,600
essentially

9401
07:59:27,350 --> 07:59:09,200
before they proceed with the hatch

9402
07:59:30,788 --> 07:59:29,190
and dragon spacex update we're still

9403
07:59:32,468 --> 07:59:30,798
investigating it looks like we'll be

9404
07:59:53,990 --> 07:59:32,478
setting up a service section purge we're

9405
07:59:58,388 --> 07:59:56,230
in case if you're just joining us

9406
08:00:00,548 --> 07:59:58,398
nasa astronauts bob bankin and doug

9407
08:00:02,310 --> 08:00:00,558
hurley have safely returned from the

9408
08:00:05,750 --> 08:00:02,320
international space station they made an

9409
08:00:09,430 --> 08:00:05,760
on-time splashdown in the gulf of mexico

9410
08:00:10,310 --> 08:00:09,440
just off the coast of pensacola florida

9411
08:00:13,350 --> 08:00:10,320
at

9412
08:00:16,388 --> 08:00:13,360
11 48 a.m pacific

9413
08:00:18,310 --> 08:00:16,398
18 48 a.m

9414
08:00:20,310 --> 08:00:18,320
universal time

9415
08:00:22,468 --> 08:00:20,320
and they have been pulled out of the

9416
08:00:24,548 --> 08:00:22,478
water and hoisted onto the recovery

9417
08:00:28,150 --> 08:00:24,558
vessel go navigator

9418
08:00:30,150 --> 08:00:28,160
and right now the team is uh just

9419
08:00:32,788 --> 08:00:30,160
completing uh they did a an initial

9420
08:00:35,030 --> 08:00:32,798
check and found that there might be some

9421
08:00:37,910 --> 08:00:35,040
remnant vapors which we certainly don't

9422
08:00:39,830 --> 08:00:37,920
want to be around when we have

9423
08:00:40,628 --> 08:00:39,840
bob and doug coming out of the capsule

9424
08:00:42,628 --> 08:00:40,638
so

9425
08:00:43,910 --> 08:00:42,638
the team is

9426
08:00:46,948 --> 08:00:43,920
working to

9427
08:00:51,910 --> 08:00:46,958
purge the service section in preparation

9428
08:00:56,388 --> 08:00:53,990
just a little commentary on

9429
08:00:57,350 --> 08:00:56,398
the hatches that that we've been talking

9430
08:00:59,430 --> 08:00:57,360
about

9431
08:01:01,350 --> 08:00:59,440
so while dragon's top hatch is used to

9432
08:01:03,990 --> 08:01:01,360
connect to the international space

9433
08:01:05,670 --> 08:01:04,000
station uh that's the one that's located

9434
08:01:06,868 --> 08:01:05,680
under the nose cone which is currently

9435
08:01:08,830 --> 08:01:06,878
hidden there

9436
08:01:11,190 --> 08:01:08,840
at the top of the capsule

9437
08:01:13,030 --> 08:01:11,200
um before

9438
08:01:15,750 --> 08:01:13,040
the this is the the side hatch is what

9439
08:01:18,150 --> 08:01:15,760
is utilized utilized for uh ingress and

9440
08:01:20,788 --> 08:01:18,160
egress both on the launch pad as well as

9441
08:01:22,628 --> 08:01:20,798
coming up here on the recovery vessel

9442
08:01:24,948 --> 08:01:22,638
when the international or excuse me when

9443
08:01:26,788 --> 08:01:24,958
the capsule is docked to the

9444
08:01:29,830 --> 08:01:26,798
international space station

9445
08:01:34,230 --> 08:01:29,840
they will use the forward hatch to exit

9446
08:01:38,388 --> 08:01:35,990
something to note that once that side

9447
08:01:40,388 --> 08:01:38,398
hatch is opened it'll be the first time

9448
08:01:43,510 --> 08:01:40,398
that bob and doug have

9449
08:01:44,868 --> 08:01:43,520
gotten a breath of fresh air

9450
08:01:47,270 --> 08:01:44,878
the first time that they've been able to

9451
08:01:49,910 --> 08:01:47,280
do so in two months

9452
08:01:51,670 --> 08:01:49,920
since they boarded the falcon 9

9453
08:01:57,510 --> 08:01:51,680
at the start of their mission

9454
08:02:02,548 --> 08:01:59,510
yeah with an on time splashdown they

9455
08:02:04,788 --> 08:02:02,558
return with almost exactly 64 days

9456
08:02:06,868 --> 08:02:04,798
in space on this mission just a few

9457
08:02:10,948 --> 08:02:06,878
minutes shy of that

9458
08:02:13,830 --> 08:02:12,388
in a little bit more of a stable

9459
08:02:15,590 --> 08:02:13,840
condition now that they're on the boat

9460
08:02:17,190 --> 08:02:15,600
and not in the water

9461
08:02:18,948 --> 08:02:17,200
but again our team's just continuing to

9462
08:02:20,868 --> 08:02:18,958
step through they're they're reporting

9463
08:02:22,708 --> 08:02:20,878
that they're seeing all of the vapor

9464
08:02:24,868 --> 08:02:22,718
levels that they initially detected have

9465
08:02:27,270 --> 08:02:24,878
been dropping um in that service section

9466
08:02:28,868 --> 08:02:27,280
for dragon spacex

9467
08:02:39,030 --> 08:02:28,878
we showed that levels are declining but

9468
08:02:42,788 --> 08:02:41,030
uh and in addition just so you know we

9469
08:02:44,230 --> 08:02:42,798
are not seeing any you know leak

9470
08:02:46,070 --> 08:02:44,240
indications or anything like that these

9471
08:02:51,030 --> 08:02:46,080
are pretty small levels but we still

9472
08:02:54,230 --> 08:02:52,628
okay kathy yeah you're reading my mind

9473
08:02:56,150 --> 08:02:54,240
mike we're just wondering if you saw any

9474
08:02:57,990 --> 08:02:56,160
indications of a leap or some

9475
08:02:59,750 --> 08:02:58,000
depressurization somewhere if it sounds

9476
08:03:03,430 --> 08:02:59,760
like it's just

9477
08:03:03,440 --> 08:03:32,070
yeah that's a good read back doug

9478
08:03:34,788 --> 08:03:33,270
all right so we're just continuing to

9479
08:03:36,948 --> 08:03:34,798
get a view down

9480
08:03:40,310 --> 08:03:36,958
right at the hatch of the capsule they

9481
08:03:42,468 --> 08:03:40,320
are detecting those very small traces

9482
08:03:43,830 --> 08:03:42,478
of a couple of the hyper galls

9483
08:03:46,230 --> 08:03:43,840
the one we've heard specifically

9484
08:03:49,990 --> 08:03:46,240
mentioned was ndo or no

9485
08:03:52,788 --> 08:03:50,000
three nitrogen or no2 nitrogen dioxide

9486
08:03:55,510 --> 08:03:52,798
they are at very low levels um

9487
08:03:57,590 --> 08:03:55,520
obviously not at a very harmful level as

9488
08:03:59,430 --> 08:03:57,600
we still have people in close proximity

9489
08:04:00,948 --> 08:03:59,440
to the capsule they are going through

9490
08:04:03,430 --> 08:04:00,958
with the purge they're not seeing any

9491
08:04:05,270 --> 08:04:03,440
indications of a leak

9492
08:04:07,110 --> 08:04:05,280
in the service section of dragon that's

9493
08:04:08,388 --> 08:04:07,120
where pretty much all of those different

9494
08:04:11,430 --> 08:04:08,398
fuel tanks

9495
08:04:43,830 --> 08:04:11,440
with the hyper galls are located inside

9496
08:04:48,388 --> 08:04:46,628
and we are just about 44 minutes post

9497
08:04:50,788 --> 08:04:48,398
splash down

9498
08:04:52,468 --> 08:04:50,798
actually still ahead of the timeline

9499
08:04:54,788 --> 08:04:52,478
as we weren't expecting to get the hatch

9500
08:04:56,230 --> 08:04:54,798
open until shortly before 60 minutes at

9501
08:04:57,830 --> 08:04:56,240
which point we'd be bringing bob and

9502
08:04:58,628 --> 08:04:57,840
doug out so

9503
08:05:00,708 --> 08:04:58,638
this

9504
08:05:02,628 --> 08:05:00,718
second spacex another update the service

9505
08:05:04,468 --> 08:05:02,638
section purge should begin in a bit

9506
08:05:07,190 --> 08:05:04,478
under five minutes uh right now we're

9507
08:05:09,270 --> 08:05:07,200
showing nto about 2x of our personal

9508
08:05:13,670 --> 08:05:09,280
exposure limits and we're hoping once we

9509
08:05:13,680 --> 08:05:22,468
okay thanks

9510
08:05:27,190 --> 08:05:24,150
and i'm going to have to correct myself

9511
08:05:29,270 --> 08:05:27,200
so it's nto that's the dinitrogen

9512
08:05:32,310 --> 08:05:29,280
tetra oxide and that's one of the

9513
08:05:35,030 --> 08:05:32,320
hypergolic fuels used inside dragon for

9514
08:05:50,628 --> 08:05:35,040
powering those

9515
08:05:57,750 --> 08:05:53,590
so again the spacex engineers detecting

9516
08:06:00,468 --> 08:05:57,760
uh levels of nto

9517
08:06:02,468 --> 08:06:00,478
it's dinitrogen tetra oxide it's one of

9518
08:06:06,150 --> 08:06:02,478
the hypergolic fuels used inside the

9519
08:06:09,670 --> 08:06:08,150
levels higher than they would like so

9520
08:06:10,548 --> 08:06:09,680
they're essentially doing a purge to

9521
08:06:12,468 --> 08:06:10,558
help

9522
08:06:14,548 --> 08:06:12,478
dissipate any vapors in and around the

9523
08:06:16,708 --> 08:06:14,558
service section where those fuel tanks

9524
08:06:18,388 --> 08:06:16,718
reside in the dragon capsule we're

9525
08:06:20,150 --> 08:06:18,398
expecting that to take within the next

9526
08:06:22,230 --> 08:06:20,160
five minutes or so

9527
08:06:24,708 --> 08:06:22,240
we were still expecting the crew out

9528
08:06:27,190 --> 08:06:24,718
inside of an hour so still on the

9529
08:06:29,510 --> 08:06:27,200
timeline or a few minutes ahead and we

9530
08:06:31,750 --> 08:06:29,520
should be seeing bob and doug

9531
08:06:33,910 --> 08:06:31,760
once we see those levels continue to

9532
08:06:35,990 --> 08:06:33,920
drop around the capsule we'll begin to

9533
08:07:50,388 --> 08:06:36,000
step through the hatch opening process

9534
08:07:54,548 --> 08:07:51,830
so right now we're getting ready to

9535
08:07:56,388 --> 08:07:54,558
purge the surface section

9536
08:07:59,430 --> 08:07:56,398
this is to make sure that

9537
08:08:04,388 --> 08:07:59,440
the lingering nto fumes that the team is

9538
08:08:07,830 --> 08:08:04,398
detecting uh get flushed out essentially

9539
08:08:10,868 --> 08:08:07,840
the service section is not the interior

9540
08:08:13,270 --> 08:08:10,878
cabin where bob and doug are

9541
08:08:16,708 --> 08:08:13,280
it's actually the part of the capsule

9542
08:08:18,868 --> 08:08:16,718
that is outside of the place where bob

9543
08:08:21,750 --> 08:08:18,878
and doug are that's it's external to the

9544
08:08:23,830 --> 08:08:21,760
to the cabin but it's inside

9545
08:08:26,310 --> 08:08:23,840
the capsule itself so you can think of

9546
08:08:29,590 --> 08:08:26,320
it as the space between

9547
08:08:32,548 --> 08:08:29,600
the exterior of the dragon capsule

9548
08:08:34,708 --> 08:08:32,558
and the interior space uh where bob and

9549
08:08:36,830 --> 08:08:34,718
doug are there's i think the interior

9550
08:08:40,150 --> 08:08:36,840
pressure vessel essentially yes

9551
08:08:41,750 --> 08:08:40,160
exactly so bob and duggar find the air

9552
08:08:44,070 --> 08:08:41,760
that they are breathing

9553
08:08:46,230 --> 08:08:44,080
is you know that nitrox

9554
08:08:48,628 --> 08:08:46,240
mix that they've been getting throughout

9555
08:08:50,230 --> 08:08:48,638
the entire duration of

9556
08:08:51,510 --> 08:08:50,240
of today's

9557
08:08:55,350 --> 08:08:51,520
operations

9558
08:08:57,350 --> 08:08:55,360
but it'll be essentially the area below

9559
08:08:58,948 --> 08:08:57,360
their cabin um

9560
08:09:01,350 --> 08:08:58,958
completely

9561
08:09:03,670 --> 08:09:01,360
sealed off from the service section yeah

9562
08:09:05,350 --> 08:09:03,680
that service section is where

9563
08:09:07,270 --> 08:09:05,360
uh we there's a lot of telemetry it's

9564
08:09:08,628 --> 08:09:07,280
where

9565
08:09:10,628 --> 08:09:08,638
there are

9566
08:09:13,350 --> 08:09:10,638
the prop tanks and we're just making

9567
08:09:16,310 --> 08:09:13,360
sure that those get aerated so that

9568
08:09:17,430 --> 08:09:16,320
lingering fumes

9569
08:09:21,750 --> 08:09:17,440
are

9570
08:09:27,190 --> 08:09:24,788
again they had detected

9571
08:09:29,590 --> 08:09:27,200
higher levels than they want to see of

9572
08:09:32,150 --> 08:09:29,600
nitrogen tetra oxide

9573
08:09:33,430 --> 08:09:32,160
that's one of the two hypergolic fuels

9574
08:09:35,110 --> 08:09:33,440
used

9575
08:09:37,750 --> 08:09:35,120
in dragon the other one being

9576
08:09:40,388 --> 08:09:37,760
monomethylhydrazine

9577
08:09:42,628 --> 08:09:40,398
those two fuels essentially when thrown

9578
08:09:43,990 --> 08:09:42,638
together even without an ignition source

9579
08:09:46,310 --> 08:09:44,000
will react

9580
08:09:48,468 --> 08:09:46,320
that's what makes them hypergolic fuels

9581
08:09:51,350 --> 08:09:48,478
much simpler more elegant

9582
08:09:53,670 --> 08:09:51,360
solution used in a lot of

9583
08:10:00,548 --> 08:09:53,680
on-orbit maneuvering systems in

9584
08:10:00,558 --> 08:10:10,788
so again we're just standing by

9585
08:10:15,590 --> 08:10:13,110
so as you can see on your screen there

9586
08:10:17,830 --> 08:10:15,600
is one crew member that has kind of what

9587
08:10:19,430 --> 08:10:17,840
looks like a dragon spacex i don't have

9588
08:10:21,510 --> 08:10:19,440
a great huge update for you just letting

9589
08:10:30,150 --> 08:10:21,520
you know the service section purge is

9590
08:10:41,030 --> 08:10:31,350
and we'll try to get you out of there

9591
08:10:44,468 --> 08:10:42,868
so as i was saying two individuals on

9592
08:10:46,310 --> 08:10:44,478
your screen there one

9593
08:10:47,910 --> 08:10:46,320
with a face mask and what looks like a

9594
08:10:50,468 --> 08:10:47,920
scuba tank there

9595
08:10:52,468 --> 08:10:50,478
with some clean breathing air

9596
08:10:54,868 --> 08:10:52,478
there might be another crew member with

9597
08:10:58,708 --> 08:10:54,878
the same personal protective equipment

9598
08:11:01,030 --> 08:10:58,718
or ppe that will come on deck here

9599
08:11:02,468 --> 08:11:01,040
that type of equipment ah there we go

9600
08:11:05,190 --> 08:11:02,478
that's the kind of equipment that is

9601
08:11:06,150 --> 08:11:05,200
required in order to perform this purge

9602
08:11:09,750 --> 08:11:06,160
again

9603
08:11:11,990 --> 08:11:09,760
the nto is the fumes from that are toxic

9604
08:11:15,350 --> 08:11:12,000
and of course we want to keep all crew

9605
08:11:17,190 --> 08:11:15,360
members safe as we prepare

9606
08:11:19,110 --> 08:11:17,200
the side hatch

9607
08:11:19,990 --> 08:11:19,120
for opening in order to let bob and

9608
08:11:21,590 --> 08:11:20,000
justin

9609
08:11:24,070 --> 08:11:21,600
looks like limits

9610
08:11:25,590 --> 08:11:24,080
are dropping and getting pretty good

9611
08:11:30,628 --> 08:11:25,600
we're still continuing with the purge

9612
08:11:30,638 --> 08:11:38,788
okay that sounds good mike thank you

9613
08:11:42,628 --> 08:11:40,230
all right so we just heard the call the

9614
08:11:44,150 --> 08:11:42,638
limits continuing to drop

9615
08:11:46,868 --> 08:11:44,160
on that

9616
08:11:49,350 --> 08:11:46,878
uh that nto that nitrogen

9617
08:11:50,708 --> 08:11:49,360
tetraoxide

9618
08:11:52,388 --> 08:11:50,718
so they're just going to continue to

9619
08:11:53,990 --> 08:11:52,398
monitor those they're doing a purge

9620
08:11:56,468 --> 08:11:54,000
essentially flushing the air around the

9621
08:11:59,430 --> 08:11:56,478
service section where the tanks

9622
08:12:01,270 --> 08:11:59,440
for those hypergolic fuels are in dragon

9623
08:12:03,510 --> 08:12:01,280
as kate was talking about they're not

9624
08:12:05,350 --> 08:12:03,520
inside the pressure vessel the section

9625
08:12:07,110 --> 08:12:05,360
of the dragon interior or bob and doug

9626
08:12:08,548 --> 08:12:07,120
and their atmosphere exist

9627
08:12:11,110 --> 08:12:08,558
they're essentially outside the pressure

9628
08:13:23,430 --> 08:12:11,120
vessel but still inside the outer shell

9629
08:13:29,430 --> 08:13:27,270
and we are just about 52 minutes

9630
08:13:31,270 --> 08:13:29,440
post splashdown

9631
08:13:33,270 --> 08:13:31,280
again we're just waiting for them to get

9632
08:13:35,510 --> 08:13:33,280
good readings on the levels

9633
08:13:37,590 --> 08:13:35,520
of any hypergol vapors still in

9634
08:13:41,270 --> 08:13:37,600
existence around the capsule

9635
08:13:43,430 --> 08:13:41,280
and then they'll be able to step back in

9636
08:13:45,030 --> 08:13:43,440
to this hatch opening now we did hear

9637
08:13:47,190 --> 08:13:45,040
confirmation that they haven't seen any

9638
08:13:48,868 --> 08:13:47,200
indication of leaks to the telemetry

9639
08:13:50,230 --> 08:13:48,878
they're still receiving from the dragon

9640
08:13:52,868 --> 08:13:50,240
capsule

9641
08:14:01,110 --> 08:13:52,878
and so dragon spacex we're gonna purge

9642
08:14:05,190 --> 08:14:03,750
there we go should be one more minute

9643
08:14:07,350 --> 08:14:05,200
and then if levels have dropped

9644
08:14:08,310 --> 08:14:07,360
sufficiently we'll be able to step back

9645
08:14:19,590 --> 08:14:08,320
in

9646
08:14:19,600 --> 08:14:28,310
so

9647
08:14:33,110 --> 08:14:30,548
bob and doug will be getting assistance

9648
08:14:35,030 --> 08:14:33,120
from recovery teams while exiting

9649
08:14:36,868 --> 08:14:35,040
dragon endeavor

9650
08:14:39,670 --> 08:14:36,878
this is the same process for any

9651
08:14:41,990 --> 08:14:39,680
returning long duration crew members

9652
08:14:43,430 --> 08:14:42,000
as returning to a gravity rich

9653
08:14:45,190 --> 08:14:43,440
environment can

9654
08:14:48,708 --> 08:14:45,200
you know be a little jarring wreak havoc

9655
08:14:50,310 --> 08:14:48,718
with our vestibular system so

9656
08:14:53,110 --> 08:14:50,320
which is responsible for maintaining

9657
08:14:56,310 --> 08:14:53,120
balance and motion of course as you've

9658
08:14:58,548 --> 08:14:56,320
heard us say multiple times earlier

9659
08:15:01,510 --> 08:14:58,558
safety is our number one priority with

9660
08:15:04,070 --> 08:15:01,520
this operation so you will see both bob

9661
08:15:06,868 --> 08:15:04,080
and doug helped out of the capsule

9662
08:15:09,670 --> 08:15:06,878
and assisted to just the few feet over

9663
08:15:11,510 --> 08:15:09,680
to the medical quarters

9664
08:15:13,590 --> 08:15:11,520
aboard the boat

9665
08:15:15,750 --> 08:15:13,600
yeah if if you've ever watched

9666
08:15:18,548 --> 08:15:15,760
long-duration crews return on a soyuz

9667
08:15:19,990 --> 08:15:18,558
it's a pretty similar process where

9668
08:15:22,150 --> 08:15:20,000
they're literally carried out of the

9669
08:15:24,708 --> 08:15:22,160
capsule and immediately placed down into

9670
08:15:26,708 --> 08:15:24,718
a waiting chair where they usually get

9671
08:15:28,708 --> 08:15:26,718
some initial medical checks out there in

9672
08:15:31,190 --> 08:15:28,718
the field before they're then carried to

9673
08:15:33,510 --> 08:15:31,200
an inflatable inflated medical tent we

9674
08:15:34,948 --> 08:15:33,520
don't have a tent we have quarters and

9675
08:15:37,750 --> 08:15:34,958
they're a whole lot closer so they'll

9676
08:15:40,070 --> 08:15:37,760
just have a couple of feet to go from

9677
08:15:41,750 --> 08:15:40,080
the capsule itself into those medical

9678
08:15:43,910 --> 08:15:41,760
quarters and then once they're in there

9679
08:15:45,670 --> 08:15:43,920
they'll get some initial checkouts

9680
08:15:47,910 --> 08:15:45,680
from their flight surgeons who are on

9681
08:15:49,670 --> 08:15:47,920
location on the boat with them these are

9682
08:15:51,110 --> 08:15:49,680
the people that have essentially been

9683
08:15:53,590 --> 08:15:51,120
responsible for their health and

9684
08:15:55,590 --> 08:15:53,600
well-being throughout their mission both

9685
08:15:58,388 --> 08:15:55,600
beforehand all of their pre-flight data

9686
08:15:59,830 --> 08:15:58,398
takes uh offering them support in the

9687
08:16:01,670 --> 08:15:59,840
lead up to launch

9688
08:16:03,590 --> 08:16:01,680
and then the entire time while on board

9689
08:16:04,868 --> 08:16:03,600
the international space station and then

9690
08:16:06,548 --> 08:16:04,878
they're right here

9691
08:16:13,670 --> 08:16:06,558
with the front line with the recovery

9692
08:16:20,628 --> 08:16:15,670
so it's been just about a minute since

9693
08:16:23,750 --> 08:16:21,990
we should be just about done with the

9694
08:16:25,190 --> 08:16:23,760
purge we're going to stand by and

9695
08:16:26,788 --> 08:16:25,200
hopefully we'll resume these hatch

9696
08:17:25,750 --> 08:16:26,798
opening operations

9697
08:17:25,760 --> 08:17:31,910
try again spacex 4 update

9698
08:17:36,548 --> 08:17:33,990
okay exterior we're seeing uh three

9699
08:17:38,948 --> 08:17:36,558
parts per million nto and six parts per

9700
08:17:41,190 --> 08:17:38,958
billion of uh mmh and nil however is

9701
08:17:49,750 --> 08:17:41,200
asking that you desto your triggers and

9702
08:17:56,388 --> 08:17:53,350
yeah which detector what number mike

9703
08:18:02,708 --> 08:17:56,398
yeah it'll be uh detectors two and three

9704
08:18:02,718 --> 08:18:07,910
okay thanks doug

9705
08:18:11,590 --> 08:18:09,510
all right so we just got the the call

9706
08:18:13,750 --> 08:18:11,600
out of the current readings of both the

9707
08:18:16,708 --> 08:18:13,760
nto the nitrogen tetra oxide and the

9708
08:18:17,990 --> 08:18:16,718
monomethylhydrazine

9709
08:18:19,910 --> 08:18:18,000
either in the parts per million or the

9710
08:18:21,750 --> 08:18:19,920
parts per billion but just as an extra

9711
08:18:23,830 --> 08:18:21,760
safety precaution

9712
08:18:25,830 --> 08:18:23,840
we heard anneal so neil netten the

9713
08:18:29,590 --> 08:18:25,840
medical authority from spacex on the

9714
08:18:32,070 --> 08:18:29,600
boat asking the crew to take out some

9715
08:18:33,830 --> 08:18:32,080
air detectors that they have

9716
08:18:36,468 --> 08:18:33,840
inside with them just to do some quick

9717
08:18:38,708 --> 08:18:36,478
sampling inside the cabin itself

9718
08:18:40,788 --> 08:18:38,718
so again we've said it before we'll

9719
08:18:43,590 --> 08:18:40,798
continue to say it throughout safety the

9720
08:18:45,830 --> 08:18:43,600
top priority with this operation so the

9721
08:18:47,670 --> 08:18:45,840
teams are going to be very methodical

9722
08:18:50,150 --> 08:18:47,680
and make sure that everything is in a

9723
08:18:52,230 --> 08:18:50,160
good setup a safe environment not only

9724
08:18:55,510 --> 08:18:52,240
for the crew themselves but also for our

9725
08:18:58,150 --> 08:18:55,520
recovery forces but for now bob and dog

9726
08:19:16,948 --> 08:18:58,160
still inside of crew dragon

9727
08:19:16,958 --> 08:19:20,788
spacex dragon with a set

9728
08:19:20,798 --> 08:19:24,868
go ahead doug

9729
08:19:32,948 --> 08:19:28,548
okay for uh nr2 on detector 2 it reads

9730
08:19:40,708 --> 08:19:36,510
and on detector 3 it also reads

9731
08:19:53,110 --> 08:19:44,388
okay great news 0.0 for detectors 2 and

9732
08:19:58,708 --> 08:19:55,670
and so doug hurley reporting

9733
08:20:53,350 --> 08:19:58,718
zeros across the board no traces

9734
08:20:53,360 --> 08:21:01,030
dragon spacex for a status update

9735
08:21:05,510 --> 08:21:03,350
okay so currently our exposure limits um

9736
08:21:07,110 --> 08:21:05,520
are below limits but the purge is

9737
08:21:09,350 --> 08:21:07,120
actually doing a pretty good job we saw

9738
08:21:11,750 --> 08:21:09,360
nto go from three parts per million down

9739
08:21:13,590 --> 08:21:11,760
to 1.5 over the last few minutes so

9740
08:21:14,868 --> 08:21:13,600
ideally with a lot of caution we'd go

9741
08:21:16,388 --> 08:21:14,878
ahead and let the purge run for a little

9742
08:21:18,388 --> 08:21:16,398
bit longer but we want to see how you

9743
08:21:20,308 --> 08:21:18,398
guys are doing if you're okay with uh

9744
08:21:22,308 --> 08:21:20,318
continuing with the with the purge

9745
08:21:27,030 --> 08:21:22,318
versus uh knock it off and get you guys

9746
08:21:32,868 --> 08:21:30,468
yeah we're fine hanging out mike uh

9747
08:21:34,468 --> 08:21:32,878
no problem here

9748
08:21:36,868 --> 08:21:34,478
okay thanks for that doug we'll uh keep

9749
08:21:41,590 --> 08:21:36,878
working the purge to uh get us down and

9750
08:21:46,628 --> 08:21:43,510
yeah let's just keep everybody safe no

9751
08:21:46,638 --> 08:21:53,030
yeah we concur

9752
08:21:56,308 --> 08:21:54,708
spacecraft commander doug hurley

9753
08:21:57,350 --> 08:21:56,318
reporting the crew still doing well in

9754
08:22:00,548 --> 08:21:57,360
dragon

9755
08:22:02,708 --> 08:22:00,558
so they are good to continue to hang out

9756
08:22:05,750 --> 08:22:02,718
the medical authority there on the boat

9757
08:22:07,750 --> 08:22:05,760
recommending uh as long as the crew is

9758
08:22:09,350 --> 08:22:07,760
okay and still doing well inside dragon

9759
08:22:11,270 --> 08:22:09,360
we'll just continue with the purge

9760
08:22:14,628 --> 08:22:11,280
trying to get those

9761
08:22:16,708 --> 08:22:14,638
trace readings of any hyper golf vapors

9762
08:22:18,468 --> 08:22:16,718
all the way down to zero

9763
08:22:20,308 --> 08:22:18,478
because again we're really focused on

9764
08:22:22,708 --> 08:22:20,318
not only keeping the astronauts safe but

9765
08:22:24,788 --> 08:22:22,718
all of the recovery engineers and

9766
08:22:26,150 --> 08:22:24,798
medical professionals there on the scene

9767
08:22:27,830 --> 08:22:26,160
as well

9768
08:22:28,788 --> 08:22:27,840
so they're going to continue this purge

9769
08:22:31,430 --> 08:22:28,798
just

9770
08:22:32,868 --> 08:22:31,440
dispelling the immediate area around the

9771
08:22:36,388 --> 08:22:32,878
service section

9772
08:22:40,070 --> 08:22:36,398
of the dragon spacecraft so this is

9773
08:22:42,468 --> 08:22:40,080
really a series of fuel tanks um outside

9774
08:22:43,910 --> 08:22:42,478
of the pressure vessels so where

9775
08:22:45,590 --> 08:22:43,920
bob and doug are inside the dragon

9776
08:22:47,750 --> 08:22:45,600
spacecraft which they did

9777
08:22:50,230 --> 08:22:47,760
uh some quick readings inside the cabin

9778
08:22:52,788 --> 08:22:50,240
and had zeros across the board

9779
08:22:55,030 --> 08:22:52,798
but they're just continuing to let these

9780
08:22:57,510 --> 08:22:55,040
levels dissipate bring it down to zero

9781
08:22:59,670 --> 08:22:57,520
and then we'll resume hatch operations

9782
08:23:02,948 --> 08:22:59,680
we're just a little over an hour now an

9783
08:23:04,788 --> 08:23:02,958
hour and two minutes post splashdown

9784
08:23:06,628 --> 08:23:04,798
yeah good to hear bob and dig report

9785
08:23:08,308 --> 08:23:06,638
that they're good hanging out meaning

9786
08:23:09,910 --> 08:23:08,318
they're feeling all right and they're

9787
08:23:11,350 --> 08:23:09,920
pretty comfortable

9788
08:23:12,388 --> 08:23:11,360
staying inside for just a couple more

9789
08:23:13,910 --> 08:23:12,398
minutes

9790
08:23:15,030 --> 08:23:13,920
yeah they were they were doing their

9791
08:23:17,990 --> 08:23:15,040
best uh

9792
08:23:21,270 --> 08:23:18,000
prior to leaving uh of playing up their

9793
08:23:23,110 --> 08:23:21,280
expectant seasickness

9794
08:23:24,788 --> 08:23:23,120
so good it is good to hear that they're

9795
08:24:04,948 --> 08:23:24,798
doing well still inside the dragon

9796
08:24:08,468 --> 08:24:06,708
and uh dragon spacex we're still seeing

9797
08:24:11,030 --> 08:24:08,478
good indications from the purge we're

9798
08:24:13,190 --> 08:24:11,040
looking to go about another five minutes

9799
08:24:15,190 --> 08:24:13,200
and looking for zero indications if at

9800
08:24:19,510 --> 08:24:15,200
any time you'd like us to speed things

9801
08:24:24,230 --> 08:24:21,110
we're good just keep doing what you're

9802
08:24:29,510 --> 08:24:24,240
doing where you can wait for five easy

9803
08:24:33,430 --> 08:24:31,430
all right so we'll settle in at least

9804
08:24:35,110 --> 08:24:33,440
another five minutes while they just

9805
08:24:36,868 --> 08:24:35,120
continue to

9806
08:24:38,708 --> 08:24:36,878
disperse any trace remnants of those

9807
08:24:39,910 --> 08:24:38,718
hypergol fuels around the service

9808
08:24:43,030 --> 08:24:39,920
section

9809
08:24:44,788 --> 08:24:43,040
of dragon before we once again step into

9810
08:24:47,270 --> 08:24:44,798
the hatch opening we're gonna we're

9811
08:24:49,590 --> 08:24:47,280
gonna stay with you stay with this until

9812
08:24:55,750 --> 08:24:49,600
bob and doug are out of the capsule and

9813
08:25:01,190 --> 08:24:58,628
at this point bob and doug are still

9814
08:25:02,788 --> 08:25:01,200
strapped into their seats the seats have

9815
08:25:04,628 --> 08:25:02,798
actuated

9816
08:25:06,388 --> 08:25:04,638
away from the

9817
08:25:08,150 --> 08:25:06,398
position where i guess in the

9818
08:25:09,750 --> 08:25:08,160
orientation in which you see the capsule

9819
08:25:12,868 --> 08:25:09,760
now

9820
08:25:14,788 --> 08:25:12,878
during their on-orbit excuse me during

9821
08:25:17,110 --> 08:25:14,798
the departure

9822
08:25:19,750 --> 08:25:17,120
phasing earlier this morning and

9823
08:25:21,190 --> 08:25:19,760
yesterday the orientation of the seats

9824
08:25:22,708 --> 08:25:21,200
were such that

9825
08:25:25,270 --> 08:25:22,718
essentially bob and doug would have been

9826
08:25:27,350 --> 08:25:25,280
laying on their backs in the orientation

9827
08:25:30,548 --> 08:25:27,360
where we see dragon now

9828
08:25:31,990 --> 08:25:30,558
currently the seats have actuated upward

9829
08:25:34,628 --> 08:25:32,000
slightly so

9830
08:25:36,468 --> 08:25:34,638
they are not completely upright but they

9831
08:25:37,270 --> 08:25:36,478
are reclined a little bit nice and comfy

9832
08:25:40,150 --> 08:25:37,280
there

9833
08:25:41,990 --> 08:25:40,160
but they are able to see in and out of

9834
08:25:46,948 --> 08:25:42,000
those windows there that we see on

9835
08:25:51,190 --> 08:25:49,830
and then once they're able to finish the

9836
08:25:52,070 --> 08:25:51,200
really

9837
08:25:54,230 --> 08:25:52,080
the

9838
08:25:55,510 --> 08:25:54,240
egress process getting bob and doug out

9839
08:25:56,868 --> 08:25:55,520
of the capsule

9840
08:26:00,230 --> 08:25:56,878
once they're in the medical area they'll

9841
08:26:01,270 --> 08:26:00,240
look to start bringing in the helicopter

9842
08:26:02,308 --> 08:26:01,280
as

9843
08:26:03,750 --> 08:26:02,318
both

9844
08:26:06,468 --> 08:26:03,760
a bomb and dug are going to be flown

9845
08:26:09,030 --> 08:26:06,478
back to pensacola via helicopter

9846
08:26:10,308 --> 08:26:09,040
getting them to the shore in just a

9847
08:26:11,670 --> 08:26:10,318
matter of minutes

9848
08:26:13,750 --> 08:26:11,680
where a nasa plane is going to be

9849
08:26:15,830 --> 08:26:13,760
standing by to then

9850
08:26:17,590 --> 08:26:15,840
load them up and bring them home to

9851
08:26:49,030 --> 08:26:17,600
ellington airfield at the johnson space

9852
08:26:52,548 --> 08:26:51,030
and a dragon spacex things are still

9853
08:26:55,430 --> 08:26:52,558
trending well we're expecting another

9854
08:26:57,110 --> 08:26:55,440
reading in about two minutes so at 1956

9855
08:27:01,350 --> 08:26:57,120
and looking to hopefully egress you guys

9856
08:27:01,360 --> 08:27:12,230
okay sounds good bud thank you

9857
08:27:16,308 --> 08:27:14,388
in light of one of the social media

9858
08:27:18,628 --> 08:27:16,318
questions that we were asked earlier

9859
08:27:21,190 --> 08:27:18,638
someone asked if bob and doug have

9860
08:27:23,510 --> 08:27:21,200
netflix available on their heads-up

9861
08:27:24,628 --> 08:27:23,520
displays there in the capsule and uh

9862
08:27:26,548 --> 08:27:24,638
they've been they've actually been

9863
08:27:27,910 --> 08:27:26,558
pretty busy throughout

9864
08:27:30,548 --> 08:27:27,920
this mission you know monitoring

9865
08:27:31,990 --> 08:27:30,558
telemetry and data and checking for

9866
08:27:34,150 --> 08:27:32,000
timing

9867
08:27:36,548 --> 08:27:34,160
and i would say now's about the time

9868
08:27:38,948 --> 08:27:36,558
that they would certainly want

9869
08:27:41,750 --> 08:27:38,958
something to watch because you know at

9870
08:27:49,190 --> 08:27:41,760
this point their only job left to do is

9871
08:27:52,468 --> 08:27:51,670
has to be a feeling of just success

9872
08:27:54,070 --> 08:27:52,478
though

9873
08:27:55,990 --> 08:27:54,080
for those two

9874
08:27:57,910 --> 08:27:56,000
i mean taking taking the first flight

9875
08:28:00,948 --> 08:27:57,920
and a brand new spacecraft we knew as

9876
08:28:02,388 --> 08:28:00,958
test pilots this is something that was

9877
08:28:04,070 --> 08:28:02,398
kind of their bread and butter when they

9878
08:28:05,750 --> 08:28:04,080
were in the military and definitely

9879
08:28:06,788 --> 08:28:05,760
something they they left at the chance

9880
08:28:10,308 --> 08:28:06,798
for

9881
08:28:12,868 --> 08:28:10,318
once they became astronauts and

9882
08:28:13,910 --> 08:28:12,878
really a pretty flawless flight for

9883
08:28:16,308 --> 08:28:13,920
dragon

9884
08:28:17,270 --> 08:28:16,318
obviously we'll have all of the the post

9885
08:28:19,430 --> 08:28:17,280
flight

9886
08:28:21,030 --> 08:28:19,440
review coming up in the next several

9887
08:28:22,468 --> 08:28:21,040
weeks

9888
08:28:25,350 --> 08:28:22,478
as we

9889
08:28:27,430 --> 08:28:25,360
continue to assess all the data that we

9890
08:28:28,708 --> 08:28:27,440
receive throughout the mission and any

9891
08:28:31,190 --> 08:28:28,718
data still

9892
08:28:33,510 --> 08:28:31,200
recorded locally on dragon itself and

9893
08:28:35,110 --> 08:28:33,520
we'll be spending the next several weeks

9894
08:28:36,788 --> 08:28:35,120
going through and assessing the mission

9895
08:28:37,830 --> 08:28:36,798
and working through the certification

9896
08:28:40,070 --> 08:28:37,840
process

9897
08:28:42,548 --> 08:28:40,080
and we're already targeting

9898
08:28:44,388 --> 08:28:42,558
the first operational flight

9899
08:28:55,350 --> 08:28:44,398
currently pegged for no earlier than

9900
08:28:59,270 --> 08:28:57,110
and dragon spacex are now planning to

9901
08:29:04,070 --> 08:28:59,280
stop the purge in one minute at about 19

9902
08:29:04,080 --> 08:29:09,750
thank

9903
08:29:13,430 --> 08:29:11,590
all you well with them stopping the

9904
08:29:15,750 --> 08:29:13,440
purge in about a minute that means that

9905
08:29:18,468 --> 08:29:15,760
the levels have gone down to what they

9906
08:29:20,388 --> 08:29:18,478
were looking for and then we'll begin to

9907
08:29:21,990 --> 08:29:20,398
to step back into the hatch opening

9908
08:29:25,190 --> 08:29:22,000
process and then

9909
08:29:27,270 --> 08:29:25,200
be able to get bob and doug egressing or

9910
08:29:28,388 --> 08:29:27,280
moving out of the dragon capsule they've

9911
08:29:29,430 --> 08:29:28,398
been in there

9912
08:29:31,190 --> 08:29:29,440
for

9913
08:29:32,628 --> 08:29:31,200
a little more than 19 hours at this

9914
08:29:35,990 --> 08:29:32,638
point since they departed the space

9915
08:29:37,830 --> 08:29:36,000
station on saturday

9916
08:29:40,468 --> 08:29:37,840
they had a sleep period eight hours of

9917
08:29:42,230 --> 08:29:40,478
rest on the capsule on their way home

9918
08:29:44,628 --> 08:29:42,240
they've been up since a little bit

9919
08:29:47,990 --> 08:29:44,638
earlier this morning that weight coming

9920
08:30:05,270 --> 08:29:48,000
about 4 40 a.m pacific so a little more

9921
08:30:09,510 --> 08:30:07,990
and a dragon the purge is now complete

9922
08:30:14,150 --> 08:30:09,520
one more trigger check and then we

9923
08:30:18,868 --> 08:30:16,708
okay good news thank you

9924
08:30:21,030 --> 08:30:18,878
that is good news indeed so confirmation

9925
08:30:22,388 --> 08:30:21,040
that the purge is complete and that

9926
08:30:25,030 --> 08:30:22,398
they're just going to do

9927
08:30:29,030 --> 08:30:25,040
one more test to make sure that

9928
08:30:31,510 --> 08:30:29,040
all of the fumes of concern are away

9929
08:30:34,388 --> 08:30:31,520
and that it is safe to open that side

9930
08:30:37,430 --> 08:30:34,398
hatch and retrieve bob and doug

9931
08:30:40,308 --> 08:30:37,440
once again once that side hatch is open

9932
08:30:41,430 --> 08:30:40,318
our flight surgeon will be the first to

9933
08:30:43,590 --> 08:30:41,440
say hello

9934
08:30:46,548 --> 08:30:43,600
get a quick medical checkup although

9935
08:30:48,708 --> 08:30:46,558
based on the reports that they've been

9936
08:30:50,708 --> 08:30:48,718
but that the crew have been giving us

9937
08:30:52,868 --> 08:30:50,718
along the way it sounds like they're

9938
08:30:54,308 --> 08:30:52,878
doing great they're feeling good and

9939
08:31:15,510 --> 08:30:54,318
they're pretty comfortable there inside

9940
08:31:21,590 --> 08:31:18,948
and uh dragon spacex we show 0.4 parts

9941
08:31:23,830 --> 08:31:21,600
per million on nto 18 parts per billion

9942
08:31:28,388 --> 08:31:23,840
of mmh that's below limits we are

9943
08:31:31,990 --> 08:31:30,628
okay great news thanks mike

9944
08:31:33,590 --> 08:31:32,000
all right so there's the green light

9945
08:31:35,990 --> 08:31:33,600
we've been waiting for

9946
08:31:37,590 --> 08:31:36,000
uh in fact the green light

9947
08:31:39,750 --> 08:31:37,600
we've been waiting for for

9948
08:31:42,468 --> 08:31:39,760
months at this point uh this is our

9949
08:31:44,948 --> 08:31:42,478
first opportunity to say hello to bob

9950
08:31:47,350 --> 08:31:44,958
and doug our favorite space stats

9951
08:31:49,430 --> 08:31:47,360
as they are now about to

9952
08:31:52,548 --> 08:31:49,440
egress or exit from

9953
08:31:54,628 --> 08:31:52,558
dragon crew endeavor

9954
08:31:57,350 --> 08:31:54,638
again this is the culmination of

9955
08:32:00,070 --> 08:31:57,360
what has been about a 19 hour journey

9956
08:32:01,990 --> 08:32:00,080
home all starting yesterday

9957
08:32:05,590 --> 08:32:02,000
as they departed the international space

9958
08:32:10,150 --> 08:32:07,910
so this hatch will be manually opened

9959
08:32:11,510 --> 08:32:10,160
and once doing so flight surgeon neil

9960
08:32:13,110 --> 08:32:11,520
menon will

9961
08:32:15,590 --> 08:32:13,120
say hello and make sure that they're

9962
08:32:18,708 --> 08:32:15,600
still doing all right

9963
08:32:25,030 --> 08:32:18,718
and then proceed to assist them

9964
08:32:30,468 --> 08:32:28,150
and we see the hatch is now open hatch

9965
08:32:31,510 --> 08:32:30,478
being opened at 12 59

9966
08:32:34,948 --> 08:32:31,520
p.m

9967
08:32:34,958 --> 08:32:42,070
match is open

9968
08:32:46,548 --> 08:32:44,868
so right now they're going to put a

9969
08:32:48,308 --> 08:32:46,558
piece of equipment in there that

9970
08:32:49,430 --> 08:32:48,318
basically smooths out the edges and make

9971
08:32:52,388 --> 08:32:49,440
sure

9972
08:32:54,388 --> 08:32:52,398
that it is a comfortable exit from

9973
08:32:56,548 --> 08:32:54,398
the dragon capsule just a little piece

9974
08:32:58,868 --> 08:32:56,558
of structure there to ensure that

9975
08:33:01,590 --> 08:32:58,878
the hatch will remain open and that any

9976
08:33:14,548 --> 08:33:01,600
sharp edges around that side hatch

9977
08:33:18,708 --> 08:33:16,468
the blue suit there that's one of nasa's

9978
08:33:23,350 --> 08:33:18,718
flight surgeons for the crew that's dr

9979
08:33:29,350 --> 08:33:25,830
and that hatch open coming at 12 59 p.m

9980
08:34:12,788 --> 08:33:29,360
pacific that's 1959 univer universal

9981
08:34:17,350 --> 08:34:15,110
so once again the spacex recovery team

9982
08:34:19,750 --> 08:34:17,360
is now assisting nasa astronauts bob

9983
08:34:21,110 --> 08:34:19,760
benkin and doug hurley

9984
08:34:21,910 --> 08:34:21,120
to exit

9985
08:34:24,230 --> 08:34:21,920
the

9986
08:34:25,990 --> 08:34:24,240
spacecraft

9987
08:34:29,430 --> 08:34:26,000
so we got the hatch open just about two

9988
08:34:32,708 --> 08:34:31,910
we paused for a little while as they

9989
08:34:35,270 --> 08:34:32,718
were

9990
08:34:36,788 --> 08:34:35,280
just detecting some trace amounts

9991
08:34:44,468 --> 08:34:36,798
of

9992
08:34:47,750 --> 08:34:44,478
and then once those were down back in

9993
08:34:51,830 --> 08:34:47,760
acceptable limits we were able

9994
08:34:57,270 --> 08:34:55,190
so there we see a stretcher on deck

9995
08:34:59,350 --> 08:34:57,280
this is normal this is part of the

9996
08:35:02,308 --> 08:34:59,360
standard recovery procedure

9997
08:35:04,468 --> 08:35:02,318
and it is just simply to ensure bob and

9998
08:35:06,308 --> 08:35:04,478
doug remain safe like we said

9999
08:35:07,510 --> 08:35:06,318
readjusting to gravity can be a little

10000
08:35:09,510 --> 08:35:07,520
challenging

10001
08:35:14,948 --> 08:35:09,520
dizziness can often occur especially

10002
08:35:19,750 --> 08:35:17,350
so this stretcher will just be used to

10003
08:35:21,350 --> 08:35:19,760
a standard procedure to make sure

10004
08:35:23,590 --> 08:35:21,360
that the astronauts make it over to the

10005
08:35:25,270 --> 08:35:23,600
medical tent as easily and as

10006
08:35:27,670 --> 08:35:25,280
comfortably as possible

10007
08:35:28,548 --> 08:35:27,680
yeah as we discussed the reintroduction

10008
08:35:33,190 --> 08:35:28,558
to

10009
08:35:35,030 --> 08:35:33,200
bit jarring especially on our vestibular

10010
08:35:36,070 --> 08:35:35,040
system so the stuff responsible for our

10011
08:35:39,190 --> 08:35:36,080
balance

10012
08:35:40,628 --> 08:35:39,200
and as they are on a ship underway

10013
08:35:43,350 --> 08:35:40,638
we just want to make sure we're taking

10014
08:35:46,468 --> 08:35:43,360
every possible precaution to ensure that

10015
08:36:06,948 --> 08:35:46,478
their arrival is safe and free from any

10016
08:36:11,910 --> 08:36:10,070
and working to get a few of the items

10017
08:36:13,590 --> 08:36:11,920
from the seats out of the way first

10018
08:36:15,670 --> 08:36:13,600
before they begin

10019
08:36:48,150 --> 08:36:15,680
extracting our crew members they'll be

10020
08:36:52,868 --> 08:36:50,868
as we saw during the ascent portion of

10021
08:36:54,948 --> 08:36:52,878
this mission there is enough room inside

10022
08:36:58,468 --> 08:36:54,958
the capsule for

10023
08:37:00,708 --> 08:36:58,478
them to do a backflip in microgravity

10024
08:37:01,830 --> 08:37:00,718
however considering there's a couple

10025
08:37:04,948 --> 08:37:01,840
folks in there right now from the

10026
08:37:04,958 --> 08:37:08,230
i'll catch you loud and clear

10027
08:37:12,868 --> 08:37:09,910
just a quick calm check there between

10028
08:37:14,788 --> 08:37:12,878
dragon and michigan solo from the plc i

10029
08:37:17,270 --> 08:37:14,798
just wanted to thank you guys for

10030
08:37:19,190 --> 08:37:17,280
bringing us home safe before we uh i

10031
08:37:20,628 --> 08:37:19,200
disembarked from the chip endeavor i'm

10032
08:37:22,708 --> 08:37:20,638
sure doug will have some good words for

10033
08:37:24,868 --> 08:37:22,718
you guys as well but uh thank you for

10034
08:37:26,948 --> 08:37:24,878
doing the most difficult parts and the

10035
08:37:29,190 --> 08:37:26,958
most important important parts of uh

10036
08:37:31,590 --> 08:37:29,200
human space flight getting us into orbit

10037
08:37:32,868 --> 08:37:31,600
and bringing us home safely

10038
08:37:37,190 --> 08:37:32,878
thank you again for the good ship

10039
08:37:40,548 --> 08:37:38,788
thank you bob for those awesome words

10040
08:37:41,670 --> 08:37:40,558
it's absolutely been an honor and a

10041
08:37:59,190 --> 08:37:41,680
pleasure to work with you from the

10042
08:38:03,750 --> 08:38:01,270
some initial words from

10043
08:38:05,910 --> 08:38:03,760
nasa astronaut bob bankin

10044
08:38:09,670 --> 08:38:05,920
he's in the pilot seat so you've heard

10045
08:38:14,070 --> 08:38:12,230
we're still standing by for crew members

10046
08:38:18,868 --> 08:38:14,080
to begin making their way out of the

10047
08:38:22,308 --> 08:38:20,150
and again they're going to get some

10048
08:38:24,948 --> 08:38:22,318
assistance just a couple of feet to the

10049
08:38:26,708 --> 08:38:24,958
medical quarters on board the ship

10050
08:38:27,910 --> 08:38:26,718
where they're going to be able to get

10051
08:38:30,388 --> 08:38:27,920
out of their suits that they've been

10052
08:38:32,230 --> 08:38:30,398
wearing for all the the final dynamic

10053
08:38:34,150 --> 08:38:32,240
phases of the

10054
08:38:35,430 --> 08:38:34,160
separation events the orbit burn

10055
08:38:37,190 --> 08:38:35,440
re-entry

10056
08:38:39,990 --> 08:38:37,200
splashing down

10057
08:38:49,270 --> 08:38:40,000
i'm just a little over an hour ago at 11

10058
08:38:55,270 --> 08:38:51,430
again the recovery team spacex dragon

10059
08:38:59,750 --> 08:38:57,830
go for spacex

10060
08:39:01,430 --> 08:38:59,760
we have our first view of

10061
08:39:04,868 --> 08:39:01,440
i just would like to

10062
08:39:07,110 --> 08:39:04,878
sort of reiterate what bob said and add

10063
08:39:09,030 --> 08:39:07,120
my thanks to uh

10064
08:39:10,468 --> 08:39:09,040
everybody over the last several years

10065
08:39:12,708 --> 08:39:10,478
that's either worked in hawthorne

10066
08:39:16,388 --> 08:39:12,718
mcgregor or down at the kennedy space

10067
08:39:18,868 --> 08:39:16,398
center anybody who's touched endeavor

10068
08:39:21,270 --> 08:39:18,878
you should take a moment to just cherish

10069
08:39:23,590 --> 08:39:21,280
this day especially given all the things

10070
08:39:25,510 --> 08:39:23,600
that have happened this year

10071
08:39:28,070 --> 08:39:25,520
we certainly can't thank you enough our

10072
08:39:30,628 --> 08:39:28,080
families can't thank you enough

10073
08:39:33,190 --> 08:39:30,638
just proud to be a small part of this

10074
08:39:34,548 --> 08:39:33,200
whole effort to get the

10075
08:39:37,990 --> 08:39:34,558
company

10076
08:39:40,788 --> 08:39:38,000
people to and from the space station

10077
08:39:41,750 --> 08:39:40,798
they can celebrate with each other cease

10078
08:39:43,670 --> 08:39:41,760
and

10079
08:39:46,708 --> 08:39:43,680
we'll talk to you soon hopefully in

10080
08:39:49,750 --> 08:39:48,230
thanks so much doug and you're welcome

10081
08:39:51,750 --> 08:39:49,760
and thank you so much for those kind

words and we all wish you a safe journey

10083
08:39:54,868 --> 08:39:53,520
home and a happy reunion with your

10084
08:39:57,910 --> 08:39:54,878
family soon and we look forward to

10085
08:39:59,830 --> 08:39:57,920
seeing you in person as well

10086
08:40:01,590 --> 08:39:59,840
some really nice words there from bob

10087
08:40:03,590 --> 08:40:01,600
benkin

10088
08:40:06,070 --> 08:40:03,600
there on your screen we saw

10089
08:40:07,910 --> 08:40:06,080
nasa astronaut doug hurley egressing or

10090
08:40:11,430 --> 08:40:07,920
exiting from the capsule might have been

10091
08:40:14,388 --> 08:40:11,440
hard to see on your screen there but

10092
08:40:19,590 --> 08:40:14,398
we got a thumbs up indicating that

10093
08:40:22,468 --> 08:40:21,030
i'm sorry excuse me i mixed up my

10094
08:40:24,388 --> 08:40:22,478
positions there yeah

10095
08:40:26,308 --> 08:40:24,398
those words were from doug and we have

10096
08:40:28,868 --> 08:40:26,318
bob that just came out first

10097
08:40:30,548 --> 08:40:28,878
so bob bank and the pilot the joint

10098
08:40:32,230 --> 08:40:30,558
operations commander for this mission

10099
08:40:33,350 --> 08:40:32,240
out of the capsule now

10100
08:40:36,230 --> 08:40:33,360
so he's

10101
08:40:37,910 --> 08:40:36,240
making his way over to the medical area

10102
08:40:40,070 --> 08:40:37,920
and now they're going to work to get

10103
08:40:43,830 --> 08:40:40,080
doug hurley out next

10104
08:40:48,230 --> 08:40:43,840
i think i saw a smile on bob's face

10105
08:40:51,830 --> 08:40:49,990
as they've been giving us some regular

10106
08:40:54,070 --> 08:40:51,840
status updates from inside the capsule

10107
08:40:56,230 --> 08:40:54,080
they've been feeling really good

10108
08:40:59,590 --> 08:40:56,240
and so now we're just standing by for

10109
08:41:01,830 --> 08:40:59,600
our spacecraft commander doug hurley

10110
08:41:25,990 --> 08:41:01,840
to make his way out into the fresh air

10111
08:42:32,308 --> 08:42:28,150
so

10112
08:42:34,230 --> 08:42:32,318
we should see

10113
08:42:36,868 --> 08:42:34,240
spacecraft commander doug hurley making

10114
08:42:41,110 --> 08:42:36,878
his way out of the capsule

10115
08:42:41,120 --> 08:42:54,548
we've got him seated

10116
08:42:54,558 --> 08:43:00,548
there we go another thumbs up

10117
08:43:05,750 --> 08:43:04,150
we've got some applause here

10118
08:43:08,628 --> 08:43:05,760
and as you can see in mission control a

10119
08:43:11,670 --> 08:43:08,638
standing ovation for a job well done all

10120
08:43:14,788 --> 08:43:11,680
around yeah our our crew members

10121
08:43:16,468 --> 08:43:14,798
bob and doug are now safely back home on

10122
08:43:17,750 --> 08:43:16,478
earth and

10123
08:43:19,270 --> 08:43:17,760
they're going to get checked out now by

10124
08:43:21,190 --> 08:43:19,280
the nasa medical team they're going

10125
08:43:22,948 --> 08:43:21,200
straight into the medical quarters on

10126
08:43:24,948 --> 08:43:22,958
board the ship that'll be their first

10127
08:43:26,708 --> 08:43:24,958
stop on planet earth and then they're

10128
08:43:28,868 --> 08:43:26,718
going to be making their way up into a

10129
08:43:31,110 --> 08:43:28,878
helicopter and then heading back to dry

10130
08:43:33,350 --> 08:43:31,120
land so once they're complete the team's

10131
08:43:35,350 --> 08:43:33,360
going to prepare dragon itself

10132
08:43:36,788 --> 08:43:35,360
and they're going to begin taking it

10133
08:43:37,590 --> 08:43:36,798
back to shore

10134
08:43:40,708 --> 08:43:37,600
but

10135
08:43:42,948 --> 08:43:40,718
just it's been an incredible incredible

10136
08:43:45,830 --> 08:43:42,958
mission uh this all kicked off just two

10137
08:43:47,670 --> 08:43:45,840

suspenseful clearing up the last

10142
08:43:59,030 --> 08:43:56,718
possible moment they had a flawless ride

10143
08:44:01,110 --> 08:43:59,040
to orbit a 19-hour journey to the

10144
08:44:03,990 --> 08:44:01,120
international space station where they

10145
