dan thank you tabitha

26
00:01:43,990 --> 00:01:41,680
beautiful morning beautiful launch it is

27
00:01:46,389 --> 00:01:44,000
uh it was great to put a rumble in the

28
00:01:48,389 --> 00:01:46,399
air here and and get cygnus off the

29
00:01:51,030 --> 00:01:48,399
ground and it's on on its way to the

30
00:01:53,429 --> 00:01:51,040
international space station uh it was

31
00:01:55,270 --> 00:01:53,439
just a miraculous launch and and a

32
00:01:56,630 --> 00:01:55,280
flawless countdown and these gentlemen

33
00:01:58,630 --> 00:01:56,640
will talk a lot more about that but i

34
00:02:01,350 --> 00:01:58,640
would would like to congratulate the

35
00:02:02,709 --> 00:02:01,360
orbital atk team and and all the folks

36
00:02:04,789 --> 00:02:02,719
here at the

37
00:02:06,870 --> 00:02:04,799
at the center that uh put this show on

38
00:02:08,550 --> 00:02:06,880
this morning for everybody uh again it's

39
00:02:09,830 --> 00:02:08,560
just great to have that spacecraft

40
00:02:12,229 --> 00:02:09,840
heading toward the international space

41
00:02:14,070 --> 00:02:12,239
station uh the onboard crew was able to

42
00:02:15,270 --> 00:02:14,080
uh watch the the launch live we were

43
00:02:16,869 --> 00:02:15,280
able to hook that up through the mission

44
00:02:18,150 --> 00:02:16,879
control center in houston and so they

45
00:02:21,589 --> 00:02:18,160
enjoyed the show

46
00:02:23,670 --> 00:02:21,599
uh presently uh they're fully trained uh

47
00:02:26,550 --> 00:02:23,680
the spacecraft will arrive

48
00:02:28,150 --> 00:02:26,560
on tuesday morning at about 3 50 a.m

49
00:02:31,270 --> 00:02:28,160
houston time

50
00:02:33,190 --> 00:02:31,280
where paula will use the ssrms and and

51
00:02:35,350 --> 00:02:33,200
burst it and bring it into uh into our

52
00:02:38,470 --> 00:02:35,360
node 1 nader location

53
00:02:40,229 --> 00:02:38,480
crews really rested ready to go

54
00:02:42,070 --> 00:02:40,239
they'll have a busy time in front of

55
00:02:44,470 --> 00:02:42,080
them that for the next three weeks as we

56
00:02:46,630 --> 00:02:44,480
unpack all the cargo about 7 400 pounds

57
00:02:49,509 --> 00:02:46,640
of cargo

58
00:02:51,270 --> 00:02:49,519
and and then turn that back around and

59
00:02:52,390 --> 00:02:51,280
repack it

60
00:02:54,710 --> 00:02:52,400
and

61
00:02:55,830 --> 00:02:54,720
full of disposable items which is very

62
00:02:57,750 --> 00:02:55,840
key to

63
00:02:59,110 --> 00:02:57,760
keeping the the flexibility and the

64
00:03:00,630 --> 00:02:59,120
operations on board the international

65
00:03:03,509 --> 00:03:00,640
space station

66
00:03:05,750 --> 00:03:03,519
at full tilt and plan to keep it there

67
00:03:07,750 --> 00:03:05,760
until december 3rd uh then we'll do a

68
00:03:09,910 --> 00:03:07,760
maneuver and do a test with the cygnus

69
00:03:11,990 --> 00:03:09,920
vehicle and then finally on its release

70
00:03:14,949 --> 00:03:12,000
on december 4th and so

71
00:03:18,229 --> 00:03:14,959
uh again it was a it was a great mission

72
00:03:19,750 --> 00:03:18,239
uh start today we're we're anxious to

73
00:03:22,390 --> 00:03:19,760
get cygnus on board the international

74
00:03:23,990 --> 00:03:22,400
space station and again just a hearty

75
00:03:27,750 --> 00:03:24,000
congratulations to the team that pulled

76
00:03:31,270 --> 00:03:29,110
okay thank you dan

77
00:03:32,550 --> 00:03:31,280
i'm really excited to be here after a

78
00:03:34,789 --> 00:03:32,560
really good launch

79
00:03:37,270 --> 00:03:34,799
uh today but first i'd like to uh

80
00:03:39,270 --> 00:03:37,280
to point out uh and and rewind to

81
00:03:41,750 --> 00:03:39,280
yesterday after after we aborted

82
00:03:43,430 --> 00:03:41,760
unfortunately for uh for a aircraft in

83
00:03:45,670 --> 00:03:43,440
the hazard area

84
00:03:47,509 --> 00:03:45,680
we initiated our abort processing and

85
00:03:50,390 --> 00:03:47,519
de-tanked the rocket

86
00:03:52,229 --> 00:03:50,400
and uh you know it was a good exercise

87
00:03:54,070 --> 00:03:52,239
of what we've been uh planning for which

88
00:03:54,949 --> 00:03:54,080
is the ability to count very count down

89
00:03:57,350 --> 00:03:54,959
very

90
00:03:59,589 --> 00:03:57,360
uh deep into the count really up to to

91
00:04:01,670 --> 00:03:59,599
l0 and then be able to turn around and

92
00:04:03,750 --> 00:04:01,680
launch again the next day so

93
00:04:06,229 --> 00:04:03,760
so i'd really like to thank

94
00:04:07,429 --> 00:04:06,239
our spaceport operator the mid-atlantic

95
00:04:09,589 --> 00:04:07,439
regional spaceport which is run by

96
00:04:11,990 --> 00:04:09,599
virginia space

97
00:04:14,550 --> 00:04:12,000
they just scrambled yesterday

98
00:04:16,069 --> 00:04:14,560
they brought in tankers of liquid oxygen

99
00:04:17,749 --> 00:04:16,079
to top up the storage tank because we

100
00:04:19,189 --> 00:04:17,759
always boil off a little bit

101
00:04:21,590 --> 00:04:19,199
when we do an attempt they they

102
00:04:23,830 --> 00:04:21,600
repressurize the nitrogen

103
00:04:25,670 --> 00:04:23,840
uh and then we had our our antares team

104
00:04:27,430 --> 00:04:25,680
come in the second shift crew

105
00:04:29,590 --> 00:04:27,440
they saved the vehicle after de-tanking

106
00:04:33,270 --> 00:04:29,600
it

107
00:04:35,030 --> 00:04:33,280
have to go back through put desiccant

108
00:04:36,310 --> 00:04:35,040
plugs back into the tanks and so on and

109
00:04:37,510 --> 00:04:36,320
get ready for the next attempt and that

110
00:04:39,430 --> 00:04:37,520
was all done

111
00:04:41,270 --> 00:04:39,440
very well so so really thanks to

112
00:04:44,150 --> 00:04:41,280
everybody for all the support and

113
00:04:46,950 --> 00:04:44,160
enabling us to demonstrate that that

114
00:04:48,950 --> 00:04:46,960
rapid recycle for the next day

115
00:04:50,710 --> 00:04:48,960
uh compared to yesterday today was very

116
00:04:52,950 --> 00:04:50,720
boring and that's how we like it

117
00:04:55,270 --> 00:04:52,960
the more boring the better

118
00:04:56,950 --> 00:04:55,280
can't be boring enough

119
00:04:59,189 --> 00:04:56,960
so we really we just stepped right down

120
00:05:00,870 --> 00:04:59,199
through the countdown uh really had had

121
00:05:01,670 --> 00:05:00,880
very few issues the only issue we had

122
00:05:04,230 --> 00:05:01,680
was

123
00:05:06,310 --> 00:05:04,240
uh one of the main engines we chill down

124
00:05:08,150 --> 00:05:06,320
uh the engine with liquid oxygen as soon

125
00:05:09,909 --> 00:05:08,160
as we load liquid oxygen into the tank

126
00:05:11,909 --> 00:05:09,919
it starts trickling down into the engine

127
00:05:13,670 --> 00:05:11,919
pumps and starting to chill them down

128
00:05:15,510 --> 00:05:13,680
and we had one that

129
00:05:16,870 --> 00:05:15,520
that initially it gets the pre-burner

130
00:05:19,110 --> 00:05:16,880
gets loaded with liquid oxygen and then

131
00:05:21,749 --> 00:05:19,120
it uh it warms up and

132
00:05:23,270 --> 00:05:21,759
and that liquid oxygen boils off and

133
00:05:25,029 --> 00:05:23,280
escapes and that just didn't happen fast

134
00:05:27,189 --> 00:05:25,039
enough we initiated you may have heard

135
00:05:28,469 --> 00:05:27,199
steps called the tango one that that the

136
00:05:30,870 --> 00:05:28,479
launch conductor was calling that was to

137
00:05:32,870 --> 00:05:30,880
initiate a special nitrogen purge that

138
00:05:34,870 --> 00:05:32,880
we added to try to accelerate that

139
00:05:37,029 --> 00:05:34,880
process uh and it was just taking a

140
00:05:39,990 --> 00:05:37,039
little longer longer today than uh than

141
00:05:41,590 --> 00:05:40,000
anticipated so uh so actually that we

142
00:05:44,150 --> 00:05:41,600
decided we were going to push to the end

143
00:05:46,150 --> 00:05:44,160
of the window

144
00:05:48,390 --> 00:05:46,160
anyway that turned out fortuitous it

145
00:05:50,790 --> 00:05:48,400
gave the range some more time to clear

146
00:05:52,870 --> 00:05:50,800
out uh some boats that were that were

147
00:05:54,390 --> 00:05:52,880
trending towards the hazard area and

148
00:05:55,830 --> 00:05:54,400
then there was also a report of one

149
00:05:57,350 --> 00:05:55,840
aircraft south of the hazard area that

150
00:05:59,270 --> 00:05:57,360
didn't end up actually

151
00:06:00,469 --> 00:05:59,280
uh making it far enough into the hazard

152
00:06:03,189 --> 00:06:00,479
area so

153
00:06:04,230 --> 00:06:03,199
uh along that lines just uh for everyone

154
00:06:05,990 --> 00:06:04,240
who's listening would just like to

155
00:06:08,309 --> 00:06:06,000
encourage everyone to just listen to the

156
00:06:10,230 --> 00:06:08,319
range authorities pay attention to the

157
00:06:11,590 --> 00:06:10,240
notice to airmen the notice to mariners

158
00:06:14,230 --> 00:06:11,600
that they put out weeks in advance of

159
00:06:16,469 --> 00:06:14,240
each launch and uh ask for everyone's

160
00:06:18,309 --> 00:06:16,479
cooperation to just to follow the

161
00:06:19,909 --> 00:06:18,319
direction of the range crew and the and

162
00:06:21,270 --> 00:06:19,919
the troopers that keep everybody safe

163
00:06:23,749 --> 00:06:21,280
and out of the hazard area will be able

164
00:06:25,990 --> 00:06:23,759
to to put off a good launch

165
00:06:27,990 --> 00:06:26,000
okay and then we launched

166
00:06:29,510 --> 00:06:28,000
and the first stage worked very well

167
00:06:31,830 --> 00:06:29,520
very little steering command so it was

168
00:06:32,870 --> 00:06:31,840
right on the money

169
00:06:38,790 --> 00:06:32,880
we

170
00:06:41,110 --> 00:06:38,800
that all looked really good

171
00:06:42,950 --> 00:06:41,120
overall performance was a little high

172
00:06:44,230 --> 00:06:42,960
which is which is really good

173
00:06:45,590 --> 00:06:44,240
we try to be conservative in our

174
00:06:47,670 --> 00:06:45,600
estimates so

175
00:06:50,710 --> 00:06:47,680
you know we were targeting about 190 by

176
00:06:53,990 --> 00:06:50,720
290 degrees i'm sorry 190 kilometers by

177
00:06:55,510 --> 00:06:54,000
290 kilometers and we ended up at 200 by

178
00:06:57,350 --> 00:06:55,520
333

179
00:06:59,830 --> 00:06:57,360
kilometers and that's inclined right on

180
00:07:00,950 --> 00:06:59,840
the money at 51.636

181
00:07:02,629 --> 00:07:00,960
degrees

182
00:07:03,510 --> 00:07:02,639
and so looking at the statistics that's

183
00:07:05,830 --> 00:07:03,520
about

184
00:07:07,990 --> 00:07:05,840
uh one and a half sigma high

185
00:07:10,150 --> 00:07:08,000
uh when we do our monte carlo analyses

186
00:07:11,830 --> 00:07:10,160
on the on the orbit trajectory so

187
00:07:13,510 --> 00:07:11,840
so that all looked really good

188
00:07:14,710 --> 00:07:13,520
uh and then the other target the other

189
00:07:16,469 --> 00:07:14,720
parameter retarget is the right

190
00:07:18,309 --> 00:07:16,479
ascension of ascending node of the orbit

191
00:07:20,150 --> 00:07:18,319
to make sure that that we're aligned

192
00:07:22,150 --> 00:07:20,160
with the iss orbit and that was within

193
00:07:23,510 --> 00:07:22,160
one sigma so so overall it looked like a

194
00:07:26,790 --> 00:07:23,520
really good flight

195
00:07:28,309 --> 00:07:26,800
and uh very exciting very happy and uh

196
00:07:30,629 --> 00:07:28,319
and frank it's over to you for the rest

197
00:07:32,950 --> 00:07:30,639
of the mission okay thank you

198
00:07:35,110 --> 00:07:32,960
thanks to you and the great antares team

199
00:07:36,390 --> 00:07:35,120
for a fantastic launch this morning was

200
00:07:39,270 --> 00:07:36,400
beautiful

201
00:07:42,150 --> 00:07:39,280
to see the rocket lift off the pad

202
00:07:44,629 --> 00:07:42,160
the the spacecraft is in great shape uh

203
00:07:45,909 --> 00:07:44,639
entire has put us in a great orbit as as

204
00:07:48,550 --> 00:07:45,919
he described

205
00:07:50,390 --> 00:07:48,560
um we did some initial checkout of the

206
00:07:51,589 --> 00:07:50,400
spacecraft and everything looks

207
00:07:53,430 --> 00:07:51,599
it looks great on the vehicle the

208
00:07:54,629 --> 00:07:53,440
propulsion system is working uh as

209
00:07:56,070 --> 00:07:54,639
expected

210
00:07:57,110 --> 00:07:56,080
the attitude control systems keeping the

211
00:07:59,510 --> 00:07:57,120
spacecraft pointing in the right

212
00:08:01,990 --> 00:07:59,520
direction and the big event that we do

213
00:08:05,670 --> 00:08:02,000
early on is deploy the solar rays and

214
00:08:07,270 --> 00:08:05,680
those deployed exactly as we like them

215
00:08:08,550 --> 00:08:07,280
and we that enabled us to point the

216
00:08:09,990 --> 00:08:08,560
vehicle with the solar rays pointing

217
00:08:11,430 --> 00:08:10,000
towards the sun to keep the batteries

218
00:08:13,029 --> 00:08:11,440
charged

219
00:08:14,309 --> 00:08:13,039
they uh they are they're they're

220
00:08:16,550 --> 00:08:14,319
charging now

221
00:08:18,390 --> 00:08:16,560
and um we're going to do some additional

222
00:08:19,990 --> 00:08:18,400
additional checkout of the rendezvous

223
00:08:21,270 --> 00:08:20,000
sensors that'll happen over the next few

224
00:08:24,390 --> 00:08:21,280
hours

225
00:08:26,150 --> 00:08:24,400
but the initial data all looks great

226
00:08:28,150 --> 00:08:26,160
inside the cargo module the pressure

227
00:08:29,749 --> 00:08:28,160
looks uh looks right where we wanted it

228
00:08:32,310 --> 00:08:29,759
the powered payloads are drawing current

229
00:08:33,670 --> 00:08:32,320
just like we expect so that's exciting

230
00:08:36,070 --> 00:08:33,680
so it looks like the science is in good

231
00:08:38,709 --> 00:08:36,080
shape uh inside the module

232
00:08:40,790 --> 00:08:38,719
uh what we'll do now is uh start our

233
00:08:43,350 --> 00:08:40,800
plan start our phasing and orbit raising

234
00:08:45,910 --> 00:08:43,360
to get to the iss on tuesday morning the

235
00:08:48,870 --> 00:08:45,920
first big uh burn that we'll conduct

236
00:08:50,389 --> 00:08:48,880
will be around noon eastern time today

237
00:08:51,430 --> 00:08:50,399
there'll be several those burns over the

238
00:08:54,230 --> 00:08:51,440
next

239
00:08:55,350 --> 00:08:54,240
day a little more than day and a half we

240
00:08:57,269 --> 00:08:55,360
will

241
00:08:59,430 --> 00:08:57,279
arrive at a particular point in space we

242
00:09:02,070 --> 00:08:59,440
call the joint targeting reference point

243
00:09:03,829 --> 00:09:02,080
uh early in the morning on tuesday and

244
00:09:05,030 --> 00:09:03,839
we'll we'll slowly make our way towards

245
00:09:07,269 --> 00:09:05,040
the iss

246
00:09:09,990 --> 00:09:07,279
tuesday morning and as dan talked about

247
00:09:12,949 --> 00:09:10,000
the we expect to be grappled by the

248
00:09:15,509 --> 00:09:12,959
robotic arm operated by the crew at uh 4

249
00:09:17,910 --> 00:09:15,519
50 eastern standard time

250
00:09:19,350 --> 00:09:17,920
uh tuesday morning so a nice early

251
00:09:21,350 --> 00:09:19,360
morning for the team but they're they're

252
00:09:22,389 --> 00:09:21,360
all excited i was talking to the mission

253
00:09:23,670 --> 00:09:22,399
operations team

254
00:09:25,670 --> 00:09:23,680
um

255
00:09:27,670 --> 00:09:25,680
the uh they have been excited about the

256
00:09:30,310 --> 00:09:27,680
mission yesterday was sort of a little

257
00:09:31,750 --> 00:09:30,320
bit of a dry run so that worked out okay

258
00:09:33,430 --> 00:09:31,760
they got another good night's sleep and

259
00:09:35,990 --> 00:09:33,440
they're uh they're ready to go this will

260
00:09:36,870 --> 00:09:36,000
be the fastest that will go from launch

261
00:09:38,230 --> 00:09:36,880
to

262
00:09:40,310 --> 00:09:38,240
rendezvousing with the space station

263
00:09:42,630 --> 00:09:40,320
it's always been in our plan to do this

264
00:09:44,470 --> 00:09:42,640
uh this particular time we actually can

265
00:09:46,150 --> 00:09:44,480
can exercise that

266
00:09:49,509 --> 00:09:46,160
the opportunity to do that so we're

267
00:09:51,350 --> 00:09:49,519
excited to demonstrate that as well

268
00:09:53,190 --> 00:09:51,360
so once we're once we're grappled we

269
00:09:55,590 --> 00:09:53,200
will get birthed uh we'll be on the

270
00:09:58,150 --> 00:09:55,600
station for a few weeks as dan described

271
00:09:59,990 --> 00:09:58,160
and we'll uh we'll be ready to depart

272
00:10:03,509 --> 00:10:00,000
on the third and the fourth from uh from

273
00:10:05,030 --> 00:10:03,519
the iss so uh we have a busy couple of

274
00:10:07,750 --> 00:10:05,040
days ahead of us on the cygnus side but

275
00:10:10,310 --> 00:10:07,760
given the the great uh great work by the

276
00:10:12,550 --> 00:10:10,320
antares team and the wallops team and

277
00:10:14,150 --> 00:10:12,560
the mars team in virginia space uh we're

278
00:10:16,389 --> 00:10:14,160
in a great position the great position

279
00:10:18,630 --> 00:10:16,399
to do that uh the one thing i will uh

280
00:10:20,870 --> 00:10:18,640
we'll add you as as most or all of you

281
00:10:23,110 --> 00:10:20,880
probably know we did name the spacecraft

282
00:10:25,990 --> 00:10:23,120
uh after gene cernan this is the ss gene

283
00:10:27,509 --> 00:10:26,000
cernan uh we did get a great note from

284
00:10:29,509 --> 00:10:27,519
from the sternan family this morning

285
00:10:31,350 --> 00:10:29,519
after the launch they were able to watch

286
00:10:32,949 --> 00:10:31,360
uh really expressing their appreciation

287
00:10:35,590 --> 00:10:32,959
for naming the spacecraft after mr

288
00:10:37,030 --> 00:10:35,600
cernan so for someone of his uh of his

289
00:10:39,590 --> 00:10:37,040
stature in the space industry it was

290
00:10:41,750 --> 00:10:39,600
certainly our honor to do so uh and it

291
00:10:43,509 --> 00:10:41,760
was great to get that note from them so

292
00:10:45,030 --> 00:10:43,519
uh with that we'll signal this team will

293
00:10:46,790 --> 00:10:45,040
be busy for the next day and a half and

294
00:10:49,509 --> 00:10:46,800
we're looking forward to getting uh to

295
00:10:50,949 --> 00:10:49,519
dance station on tuesday morning

296
00:10:52,310 --> 00:10:50,959
thank you frank

297
00:10:55,030 --> 00:10:52,320
if you have a question in the room

298
00:10:56,630 --> 00:10:55,040
please raise your hand identify yourself

299
00:10:57,829 --> 00:10:56,640
and your outlet and let us know who

300
00:11:00,069 --> 00:10:57,839
you're directing your question to

301
00:11:01,350 --> 00:11:00,079
whether it's dan kurt or frank and

302
00:11:03,190 --> 00:11:01,360
please wait for the microphone to reach

303
00:11:05,750 --> 00:11:03,200
you we do have a question up front from

304
00:11:09,509 --> 00:11:07,430
i'm sorry we'll start with jason and

305
00:11:11,750 --> 00:11:09,519
we'll come together sorry ken uh jason

306
00:11:13,910 --> 00:11:11,760
ryan for space flight insider half

307
00:11:15,910 --> 00:11:13,920
jokingly is nasa or orbital atk

308
00:11:17,030 --> 00:11:15,920
considering investing in surface to air

309
00:11:19,269 --> 00:11:17,040
missiles

310
00:11:21,030 --> 00:11:19,279
or maybe 50 caliber machine guns to keep

311
00:11:23,110 --> 00:11:21,040
the boats out of the way

312
00:11:24,389 --> 00:11:23,120
but all joking aside what kind of

313
00:11:26,150 --> 00:11:24,399
penalty

314
00:11:27,990 --> 00:11:26,160
do these folks who

315
00:11:29,750 --> 00:11:28,000
stray into the exclusion zone what can

316
00:11:31,110 --> 00:11:29,760
they expect to see if they do this in

317
00:11:31,990 --> 00:11:31,120
the future because we've seen this quite

318
00:11:33,750 --> 00:11:32,000
a lot

319
00:11:35,670 --> 00:11:33,760
thank you sure

320
00:11:37,110 --> 00:11:35,680
and it's it's not a joking matter right

321
00:11:39,430 --> 00:11:37,120
i mean it's trying to keep the the

322
00:11:41,750 --> 00:11:39,440
public you know safe from these

323
00:11:43,269 --> 00:11:41,760
hazardous operations as far as penalties

324
00:11:44,389 --> 00:11:43,279
i'm going to let the faa work through

325
00:11:46,389 --> 00:11:44,399
that i know

326
00:11:48,310 --> 00:11:46,399
our nasa team here at wallops is working

327
00:11:50,389 --> 00:11:48,320
with the faa already

328
00:11:52,150 --> 00:11:50,399
and i imagine

329
00:11:55,110 --> 00:11:52,160
a little bit more stringent procedures

330
00:11:56,949 --> 00:11:55,120
or notifications that will go out to the

331
00:11:59,110 --> 00:11:56,959
to the folks that uh

332
00:12:00,629 --> 00:11:59,120
uh need to be informed of what what

333
00:12:02,310 --> 00:12:00,639
they're you know getting ready to go do

334
00:12:05,269 --> 00:12:02,320
or where they're what space they're

335
00:12:07,190 --> 00:12:05,279
entering uh and i i would expect to see

336
00:12:09,110 --> 00:12:07,200
uh additional measures in place for the

337
00:12:11,829 --> 00:12:09,120
uh for the may launch of the of the next

338
00:12:14,550 --> 00:12:11,839
orbital spacecraft

339
00:12:16,069 --> 00:12:14,560
we'll come to ken in the front

340
00:12:18,629 --> 00:12:16,079
all right thank you ken kramer universe

341
00:12:19,509 --> 00:12:18,639
today northeast astronomy forum for uh

342
00:12:21,430 --> 00:12:19,519
kurt

343
00:12:23,110 --> 00:12:21,440
you you mentioned the slight over

344
00:12:25,430 --> 00:12:23,120
performance of the second stage i think

345
00:12:27,190 --> 00:12:25,440
this happened last year also

346
00:12:29,509 --> 00:12:27,200
and i was wondering how this over

347
00:12:31,430 --> 00:12:29,519
performance compared to the last one and

348
00:12:33,350 --> 00:12:31,440
the lessons learned from last year did

349
00:12:35,990 --> 00:12:33,360
you apply them was it the same or was it

350
00:12:37,430 --> 00:12:36,000
an another over performance beyond that

351
00:12:42,710 --> 00:12:37,440
and for dan

352
00:12:45,190 --> 00:12:43,910
well uh

353
00:12:47,829 --> 00:12:45,200
you know we we

354
00:12:49,750 --> 00:12:47,839
last fall's oa5 launch was the first of

355
00:12:50,870 --> 00:12:49,760
the caster 30 xl

356
00:12:52,949 --> 00:12:50,880
and

357
00:12:55,350 --> 00:12:52,959
we have a process where we

358
00:12:57,430 --> 00:12:55,360
take the static fire results so we took

359
00:12:59,110 --> 00:12:57,440
you know to qualify a solid rocket motor

360
00:13:01,350 --> 00:12:59,120
we take the solid rocker motor and if

361
00:13:04,310 --> 00:13:01,360
it's an upper stage motor we fire it in

362
00:13:06,470 --> 00:13:04,320
a large vacuum chamber basically arnold

363
00:13:08,710 --> 00:13:06,480
engineering development center it's run

364
00:13:11,509 --> 00:13:08,720
by the air force allows us to do that

365
00:13:12,629 --> 00:13:11,519
and we measure uh the total impulse out

366
00:13:14,230 --> 00:13:12,639
of the engine and then we have some

367
00:13:15,829 --> 00:13:14,240
corrections that we do

368
00:13:17,030 --> 00:13:15,839
to translate that into flight

369
00:13:18,870 --> 00:13:17,040
performance and that that's our

370
00:13:19,670 --> 00:13:18,880
propulsion model that we then

371
00:13:21,590 --> 00:13:19,680
uh

372
00:13:23,430 --> 00:13:21,600
you know do our simulations on and plan

373
00:13:25,670 --> 00:13:23,440
the flight with

374
00:13:26,790 --> 00:13:25,680
the flight last fall was a little

375
00:13:28,870 --> 00:13:26,800
higher

376
00:13:30,230 --> 00:13:28,880
than we'd expected so we did adjust the

377
00:13:32,310 --> 00:13:30,240
model

378
00:13:33,750 --> 00:13:32,320
it looks like we got very cl

379
00:13:35,590 --> 00:13:33,760
from what our g and c guys were able to

380
00:13:37,190 --> 00:13:35,600
see real time they think it's probably

381
00:13:39,670 --> 00:13:37,200
we got another result it was very close

382
00:13:41,430 --> 00:13:39,680
to oa5 we had kind of hedged our bets on

383
00:13:42,629 --> 00:13:41,440
the model coming into oa8 to be a little

384
00:13:43,829 --> 00:13:42,639
conservative we like to be a little

385
00:13:46,150 --> 00:13:43,839
conservative

386
00:13:47,670 --> 00:13:46,160
uh to not over promise and and and also

387
00:13:50,310 --> 00:13:47,680
make sure that we

388
00:13:53,030 --> 00:13:50,320
you know achieve an orbit uh even if

389
00:13:54,389 --> 00:13:53,040
there's a an anomaly so so we try to

390
00:13:55,670 --> 00:13:54,399
error on the high side there's a big

391
00:13:57,910 --> 00:13:55,680
difference between

392
00:14:00,150 --> 00:13:57,920
uh making an orbit and not making an

393
00:14:02,310 --> 00:14:00,160
orbit versus you know a little

394
00:14:03,670 --> 00:14:02,320
difference on the high side is kind of

395
00:14:05,350 --> 00:14:03,680
immaterial since

396
00:14:07,030 --> 00:14:05,360
cygnus has such a capable propulsion

397
00:14:08,470 --> 00:14:07,040
system so so that's how we do the

398
00:14:10,310 --> 00:14:08,480
mission design to be more conservative

399
00:14:11,990 --> 00:14:10,320
and protect against anomalies and so i

400
00:14:13,590 --> 00:14:12,000
think we will make an update to the

401
00:14:15,189 --> 00:14:13,600
model for next time

402
00:14:17,189 --> 00:14:15,199
but we we will continue to err on the

403
00:14:19,189 --> 00:14:17,199
conservative side

404
00:14:20,790 --> 00:14:19,199
and on the one-year crew

405
00:14:23,430 --> 00:14:20,800
there is no doubt our human research

406
00:14:25,430 --> 00:14:23,440
program they have a strong desire to fly

407
00:14:28,069 --> 00:14:25,440
additional one-year crew members and so

408
00:14:30,629 --> 00:14:28,079
we're our goal is to try to meet that i

409
00:14:32,550 --> 00:14:30,639
don't see that happening as long as

410
00:14:34,870 --> 00:14:32,560
we're still flying with the on the soyuz

411
00:14:37,030 --> 00:14:34,880
and doing our our crew members flights

412
00:14:38,949 --> 00:14:37,040
on those vehicles but once we step into

413
00:14:40,870 --> 00:14:38,959
commercial crew and get a good cadence

414
00:14:42,949 --> 00:14:40,880
and a regular basis going there i think

415
00:14:45,670 --> 00:14:42,959
you'll see uh one of your crew members

416
00:14:47,030 --> 00:14:45,680
come back into play

417
00:14:48,550 --> 00:14:47,040
once again if you have a question in the

418
00:14:51,189 --> 00:14:48,560
room please raise your hand wait for the

419
00:14:53,189 --> 00:14:51,199
microphone to get to you

420
00:14:55,189 --> 00:14:53,199
john brett schneider federal times and

421
00:14:57,110 --> 00:14:55,199
defense news

422
00:15:00,629 --> 00:14:57,120
what is the

423
00:15:03,509 --> 00:15:00,639
range distance that you want boats

424
00:15:06,389 --> 00:15:03,519
and aircraft to stay away

425
00:15:09,509 --> 00:15:06,399
most of us don't have access to notices

426
00:15:13,189 --> 00:15:09,519
tear men and notices to seamen

427
00:15:15,189 --> 00:15:13,199
so how far away do you want them

428
00:15:17,030 --> 00:15:15,199
you guys know i i'd have to get back to

429
00:15:18,790 --> 00:15:17,040
you on that or we could uh you know

430
00:15:20,790 --> 00:15:18,800
certainly have uh

431
00:15:22,629 --> 00:15:20,800
we'll get information to tabitha i mean

432
00:15:24,310 --> 00:15:22,639
the local the local range people and the

433
00:15:26,790 --> 00:15:24,320
ksc range people those are the folks

434
00:15:28,470 --> 00:15:26,800
that uh put all that that practice into

435
00:15:30,230 --> 00:15:28,480
place and i'm just not aware of the of

436
00:15:31,910 --> 00:15:30,240
the actuals

437
00:15:33,910 --> 00:15:31,920
yeah i don't have the

438
00:15:36,310 --> 00:15:33,920
exact distances i know that the range

439
00:15:38,310 --> 00:15:36,320
roughly i think it's it's ten ten days

440
00:15:39,749 --> 00:15:38,320
to two weeks out they post the notice to

441
00:15:40,790 --> 00:15:39,759
airmen and notice to mariners those get

442
00:15:42,230 --> 00:15:40,800
posted

443
00:15:44,550 --> 00:15:42,240
and issued

444
00:15:46,470 --> 00:15:44,560
to the faa and to

445
00:15:48,629 --> 00:15:46,480
maritime organizations

446
00:15:50,230 --> 00:15:48,639
and they're i think they're available

447
00:15:51,670 --> 00:15:50,240
via wallops so

448
00:15:53,430 --> 00:15:51,680
so all the commercial operators

449
00:15:55,829 --> 00:15:53,440
certainly are aware of all that

450
00:15:57,829 --> 00:15:55,839
and and there's no uh

451
00:15:59,910 --> 00:15:57,839
there's no inability to find those uh

452
00:16:01,110 --> 00:15:59,920
notices uh

453
00:16:03,030 --> 00:16:01,120
i think all the pilots know where to

454
00:16:04,710 --> 00:16:03,040
find them we just uh and then on the on

455
00:16:06,710 --> 00:16:04,720
folks on the ground you know there's

456
00:16:09,189 --> 00:16:06,720
roadblocks that set up and the troopers

457
00:16:11,269 --> 00:16:09,199
are blocking off various roads uh so we

458
00:16:12,710 --> 00:16:11,279
just asked that everybody you know

459
00:16:14,710 --> 00:16:12,720
listen to the directions that you're

460
00:16:17,189 --> 00:16:14,720
given and not try to you know get the

461
00:16:19,110 --> 00:16:17,199
hero shot with your uh long-range camera

462
00:16:20,870 --> 00:16:19,120
and go around a roadblock or be clever

463
00:16:23,269 --> 00:16:20,880
and drape through the woods and enter

464
00:16:25,829 --> 00:16:23,279
the hazard area or take your boat into

465
00:16:26,949 --> 00:16:25,839
the into the back bay and uh and uh

466
00:16:29,269 --> 00:16:26,959
because you'll end up scrubbing it for

467
00:16:31,030 --> 00:16:29,279
everybody and and you know that's no fun

468
00:16:32,949 --> 00:16:31,040
for for anyone it costs everyone

469
00:16:35,189 --> 00:16:32,959
additional money so so that's what we

470
00:16:36,790 --> 00:16:35,199
ask is just to follow the directions and

471
00:16:37,910 --> 00:16:36,800
the guidance from the authorities

472
00:16:39,430 --> 00:16:37,920
appreciate that

473
00:16:41,350 --> 00:16:39,440
you also have

474
00:16:43,749 --> 00:16:41,360
a coast guard station here what's the

475
00:16:46,629 --> 00:16:43,759
possibility of bringing in additional

476
00:16:49,350 --> 00:16:46,639
coast guard assets whether it be

477
00:16:52,949 --> 00:16:49,360
surface craft or aircraft

478
00:16:55,749 --> 00:16:52,959
just to help out uh to scare away

479
00:16:57,590 --> 00:16:55,759
sure you know the intruders in fact i we

480
00:16:58,870 --> 00:16:57,600
had that very discussion this morning

481
00:17:00,230 --> 00:16:58,880
that's kind of why i mentioned i i

482
00:17:02,150 --> 00:17:00,240
assume there's some additional measures

483
00:17:03,509 --> 00:17:02,160
can be put in place in may so i just

484
00:17:06,150 --> 00:17:03,519
need to let that team that's working

485
00:17:08,470 --> 00:17:06,160
this go go work the problem and come up

486
00:17:10,870 --> 00:17:08,480
with solutions and and i bet they'll

487
00:17:12,230 --> 00:17:10,880
they'll be put into execution on for the

488
00:17:14,230 --> 00:17:12,240
for the next launch out of out of

489
00:17:15,829 --> 00:17:14,240
wallops

490
00:17:18,309 --> 00:17:15,839
we'll go now to a couple of questions

491
00:17:31,190 --> 00:17:18,319
from ask nasa

492
00:17:34,630 --> 00:17:32,630
this first question comes from a

493
00:17:36,150 --> 00:17:34,640
space.com reporter who's asking i was

494
00:17:39,590 --> 00:17:36,160
wondering if there are any thanksgiving

495
00:17:40,870 --> 00:17:39,600
food items or christmas gifts on cygnus

496
00:17:43,669 --> 00:17:40,880
uh

497
00:17:45,830 --> 00:17:43,679
i'm not aware of any specifics but it is

498
00:17:47,510 --> 00:17:45,840
customary that we fly

499
00:17:49,190 --> 00:17:47,520
thanksgiving food items up to the

500
00:17:50,870 --> 00:17:49,200
international space station so i don't

501
00:17:53,510 --> 00:17:50,880
know exactly what we flew but i bet

502
00:17:55,990 --> 00:17:53,520
there's uh those types of food groups uh

503
00:17:58,950 --> 00:17:56,000
on this flight and as far as christmas

504
00:18:00,390 --> 00:17:58,960
gifts a lot of the families do send

505
00:18:02,630 --> 00:18:00,400
christmas presents

506
00:18:04,870 --> 00:18:02,640
up to their uh you know they're given a

507
00:18:07,750 --> 00:18:04,880
certain allocation for any given mission

508
00:18:09,430 --> 00:18:07,760
and uh typically around the holidays

509
00:18:11,430 --> 00:18:09,440
they make use of that with with some

510
00:18:13,110 --> 00:18:11,440
gifts

511
00:18:15,350 --> 00:18:13,120
wonderful next question here comes from

512
00:18:16,950 --> 00:18:15,360
katrina on twitter who asks

513
00:18:18,789 --> 00:18:16,960
curious what happens to the antares

514
00:18:22,390 --> 00:18:18,799
second stage after cygnus is deployed

515
00:18:27,110 --> 00:18:25,190
uh yeah it does it uh it's in the same

516
00:18:30,549 --> 00:18:27,120
orbit as cygnus so that orbit parameter

517
00:18:32,310 --> 00:18:30,559
that i read out there 200 by 333

518
00:18:34,470 --> 00:18:32,320
that's uh not too far outside the

519
00:18:36,549 --> 00:18:34,480
atmosphere so that orbit will not last

520
00:18:37,990 --> 00:18:36,559
too long uh probably upwards of three

521
00:18:40,230 --> 00:18:38,000
weeks to a month

522
00:18:42,070 --> 00:18:40,240
uh we are you know things that affect

523
00:18:43,430 --> 00:18:42,080
how long you stay in orbit

524
00:18:45,430 --> 00:18:43,440
have to do with

525
00:18:48,310 --> 00:18:45,440
whether you're stable or not and how

526
00:18:49,110 --> 00:18:48,320
heavy you are and your

527
00:18:51,110 --> 00:18:49,120
your

528
00:18:52,710 --> 00:18:51,120
ballistic coefficient and so on and then

529
00:18:55,190 --> 00:18:52,720
also the atmosphere is not always the

530
00:18:57,270 --> 00:18:55,200
same height and it varies in height

531
00:18:59,029 --> 00:18:57,280
in accordance with a number of things so

532
00:19:01,190 --> 00:18:59,039
uh over time it will re-enter the

533
00:19:02,310 --> 00:19:01,200
atmosphere and burn up so it's not

534
00:19:05,830 --> 00:19:02,320
designed to make it through the

535
00:19:08,950 --> 00:19:07,510
all right another question here comes

536
00:19:11,270 --> 00:19:08,960
from fourth and fifth grade math and

537
00:19:12,950 --> 00:19:11,280
science students in the bronx who ask

538
00:19:15,510 --> 00:19:12,960
what are the orbital maneuvering

539
00:19:17,669 --> 00:19:15,520
capabilities of the cygnus ss gene

540
00:19:19,510 --> 00:19:17,679
cernan

541
00:19:22,630 --> 00:19:19,520
uh let's see orbital maneuver capability

542
00:19:24,390 --> 00:19:22,640
so the spacecraft is designed to be able

543
00:19:26,470 --> 00:19:24,400
to

544
00:19:28,150 --> 00:19:26,480
rotate

545
00:19:29,669 --> 00:19:28,160
translate meaning moving back and forth

546
00:19:31,510 --> 00:19:29,679
or sideways

547
00:19:32,870 --> 00:19:31,520
flip over if it needs to

548
00:19:33,909 --> 00:19:32,880
it's what we call a six degree of

549
00:19:35,590 --> 00:19:33,919
freedom

550
00:19:37,430 --> 00:19:35,600
spacecraft so

551
00:19:39,909 --> 00:19:37,440
we have 32

552
00:19:41,430 --> 00:19:39,919
thrusters mounted around the spacecraft

553
00:19:44,310 --> 00:19:41,440
in various

554
00:19:46,390 --> 00:19:44,320
places and depending on which thrusters

555
00:19:49,830 --> 00:19:46,400
you fire and for how long

556
00:19:51,350 --> 00:19:49,840
you can you can move the spacecraft

557
00:19:54,710 --> 00:19:51,360
pretty much any any which way it needs

558
00:19:56,950 --> 00:19:54,720
to we also have one large engine on it

559
00:19:58,710 --> 00:19:56,960
uh then that's the engine that we use to

560
00:20:00,070 --> 00:19:58,720
to raise the orbit

561
00:20:01,510 --> 00:20:00,080
so um

562
00:20:03,669 --> 00:20:01,520
we'll be using that engine from now

563
00:20:05,669 --> 00:20:03,679
through uh early tuesday morning and

564
00:20:07,990 --> 00:20:05,679
then when we get closer we'll only use

565
00:20:09,430 --> 00:20:08,000
the smaller engines but

566
00:20:11,830 --> 00:20:09,440
between the engines we have their

567
00:20:13,830 --> 00:20:11,840
locations the fuel we have on board

568
00:20:16,070 --> 00:20:13,840
cygnus can pretty much move in any which

569
00:20:18,149 --> 00:20:16,080
way

570
00:20:20,870 --> 00:20:18,159
one more question from nasa social sure

571
00:20:22,870 --> 00:20:20,880
this comes from uh phillip who asks does

572
00:20:24,630 --> 00:20:22,880
antares use one engine with two nozzles

573
00:20:26,630 --> 00:20:24,640
similar to an atlas v

574
00:20:27,990 --> 00:20:26,640
with the rd180 or is it two separate

575
00:20:32,149 --> 00:20:28,000
engines

576
00:20:34,630 --> 00:20:32,159
has its own turbo pump and is considered

577
00:20:36,390 --> 00:20:34,640
its own unit which is different from the

578
00:20:39,350 --> 00:20:36,400
rd180 which has a single turbo pump that

579
00:20:40,630 --> 00:20:39,360
feeds two thrust chambers

580
00:20:52,789 --> 00:20:40,640
once again if you have a question in the

581
00:20:56,230 --> 00:20:54,470
quick question for kurt with that extra

582
00:20:58,390 --> 00:20:56,240
oomph that the interior seems to have

583
00:20:59,830 --> 00:20:58,400
since you guys have put those rd-181s in

584
00:21:00,789 --> 00:20:59,840
it can you guys tell us a little bit

585
00:21:02,310 --> 00:21:00,799
about what

586
00:21:04,390 --> 00:21:02,320
is that starting to guide how orbital

587
00:21:05,750 --> 00:21:04,400
atk is thinking about using the rocket

588
00:21:07,430 --> 00:21:05,760
because now it's like okay we got a

589
00:21:09,190 --> 00:21:07,440
little more performance that it's

590
00:21:10,549 --> 00:21:09,200
capable of delivering

591
00:21:12,230 --> 00:21:10,559
can you maybe give us a preview of what

592
00:21:15,510 --> 00:21:12,240
we might be able to expect in the future

593
00:21:19,029 --> 00:21:17,510
well i think uh as i said earlier you

594
00:21:20,230 --> 00:21:19,039
know we we try to be conservative and

595
00:21:21,990 --> 00:21:20,240
make sure we can live up to our

596
00:21:24,950 --> 00:21:22,000
contractual obligations

597
00:21:27,270 --> 00:21:24,960
uh uh between antares and cygnus we have

598
00:21:29,430 --> 00:21:27,280
a really an integrated mission design

599
00:21:31,590 --> 00:21:29,440
and uh and we have margin to make sure

600
00:21:33,909 --> 00:21:31,600
that we're able to carry the cargo that

601
00:21:36,950 --> 00:21:33,919
we've we've contracted for

602
00:21:38,310 --> 00:21:36,960
i think we are in a good place now uh as

603
00:21:39,110 --> 00:21:38,320
i as i mentioned earlier we're going to

604
00:21:41,190 --> 00:21:39,120
be

605
00:21:42,830 --> 00:21:41,200
adjusting our models and when we do that

606
00:21:45,990 --> 00:21:42,840
we'll be able to bank a little bit more

607
00:21:48,070 --> 00:21:46,000
margin how we use that margin

608
00:21:49,990 --> 00:21:48,080
we're talking to cygnus and we're

609
00:21:51,590 --> 00:21:50,000
talking to nasa about how we might be

610
00:21:53,909 --> 00:21:51,600
able to use that to to everyone's

611
00:21:56,789 --> 00:21:53,919
benefit

612
00:21:59,430 --> 00:21:56,799
in addition uh next year

613
00:22:00,789 --> 00:21:59,440
we are looking to possibly add some

614
00:22:02,230 --> 00:22:00,799
secondaries

615
00:22:03,430 --> 00:22:02,240
some educate small educational

616
00:22:05,350 --> 00:22:03,440
satellites

617
00:22:07,590 --> 00:22:05,360
uh in conjunction with virginia space

618
00:22:08,950 --> 00:22:07,600
there's a program called thinsat if you

619
00:22:10,390 --> 00:22:08,960
go to the virginia space website you can

620
00:22:11,190 --> 00:22:10,400
read about the thinset program these are

621
00:22:15,270 --> 00:22:11,200
very

622
00:22:16,870 --> 00:22:15,280
ride on the second stage and not stay in

623
00:22:18,950 --> 00:22:16,880
orbit for too long but be

624
00:22:21,190 --> 00:22:18,960
really uh an education serve an

625
00:22:22,470 --> 00:22:21,200
educational purpose for uh schools

626
00:22:23,990 --> 00:22:22,480
around the commonwealth and some other

627
00:22:25,669 --> 00:22:24,000
states so we're really excited about

628
00:22:28,230 --> 00:22:25,679
that this this kind of margin would

629
00:22:31,110 --> 00:22:28,240
enable those kinds of secondary missions

630
00:22:32,310 --> 00:22:31,120
uh to be possible too but uh you know

631
00:22:33,669 --> 00:22:32,320
we're also interested in just you know

632
00:22:35,430 --> 00:22:33,679
making that available to cygnus and

633
00:22:39,590 --> 00:22:35,440
seeing how how that can improve the

634
00:22:44,470 --> 00:22:42,390
thank you kurt thank you frank and dan

635
00:22:46,630 --> 00:22:44,480
with that we'll conclude today just a

636
00:22:48,870 --> 00:22:46,640
reminder that cygnus will rendezvous

637
00:22:51,350 --> 00:22:48,880
with the space station on tuesday

638
00:22:54,149 --> 00:22:51,360
astronauts on board will use the robotic

639
00:22:57,350 --> 00:22:54,159
arm to capture the spacecraft about 4 50
