thanks rob and uh

22
00:00:48,630 --> 00:00:47,200
good afternoon everyone i'll i'll uh

23
00:00:50,709 --> 00:00:48,640
defer the conversation about the

24
00:00:53,510 --> 00:00:50,719
specifics of the evas to

25
00:00:55,670 --> 00:00:53,520
scott and and keith and jackie but from

26
00:00:57,670 --> 00:00:55,680
a big picture perspective i'll tell you

27
00:00:59,270 --> 00:00:57,680
things are going very well on board the

28
00:01:01,590 --> 00:00:59,280
space station

29
00:01:04,229 --> 00:01:01,600
as most of you know last week we had the

30
00:01:06,149 --> 00:01:04,239
arrival of 40s

31
00:01:08,789 --> 00:01:06,159
which allowed us to increase our crew

32
00:01:11,030 --> 00:01:08,799
complement back up to three on the usos

33
00:01:13,270 --> 00:01:11,040
with the addition of butch wilmore

34
00:01:15,590 --> 00:01:13,280
i'll tell you bill as uh or butch is

35
00:01:17,510 --> 00:01:15,600
doing a great job uh he's pretty much

36
00:01:20,070 --> 00:01:17,520
got his space legs up under him now he's

37
00:01:21,670 --> 00:01:20,080
he's making contributions to to the team

38
00:01:23,270 --> 00:01:21,680
and doing a great job and so we're

39
00:01:24,310 --> 00:01:23,280
looking forward to having him aboard for

40
00:01:25,590 --> 00:01:24,320
the next

41
00:01:28,149 --> 00:01:25,600
six months

42
00:01:30,950 --> 00:01:28,159
um he uh he joined reid wiseman and

43
00:01:32,630 --> 00:01:30,960
alexander gerst uh those two guys have

44
00:01:34,310 --> 00:01:32,640
been doing a great job well while

45
00:01:37,190 --> 00:01:34,320
they've been down at a crew of three on

46
00:01:39,749 --> 00:01:37,200
the station and uh it's good to have the

47
00:01:42,069 --> 00:01:39,759
the crew back up to six again

48
00:01:43,830 --> 00:01:42,079
this crew of three on the usos will be

49
00:01:45,590 --> 00:01:43,840
together for about a month

50
00:01:48,950 --> 00:01:45,600
we'll plan to bring

51
00:01:50,950 --> 00:01:48,960
alexander and reid home on november 10th

52
00:01:52,870 --> 00:01:50,960
and between now and then they've got an

53
00:01:54,630 --> 00:01:52,880
awful lot of work to do

54
00:01:57,510 --> 00:01:54,640
just about a week ago a little over a

55
00:01:58,389 --> 00:01:57,520
week ago we birthed the spacex dragon

56
00:02:00,469 --> 00:01:58,399
for the

57
00:02:02,789 --> 00:02:00,479
third excuse me the fourth of the

58
00:02:04,310 --> 00:02:02,799
commercial resupply flights that spacex

59
00:02:06,709 --> 00:02:04,320
is doing for us

60
00:02:09,029 --> 00:02:06,719
that particular dragon had a large

61
00:02:11,589 --> 00:02:09,039
complement of science and payloads on it

62
00:02:13,589 --> 00:02:11,599
and these guys are off uh knocking the

63
00:02:16,949 --> 00:02:13,599
science out and doing a great job and

64
00:02:19,030 --> 00:02:16,959
and so far so good

65
00:02:20,470 --> 00:02:19,040
in the midst of all that uh we're

66
00:02:21,990 --> 00:02:20,480
planning for a couple evas that you're

67
00:02:23,430 --> 00:02:22,000
going to hear the details about here

68
00:02:25,670 --> 00:02:23,440
shortly

69
00:02:28,070 --> 00:02:25,680
so so we'll get these evas done do the

70
00:02:31,430 --> 00:02:28,080
science on spacex and then on or about

71
00:02:32,869 --> 00:02:31,440
the the 21st of october we'll plan to

72
00:02:35,030 --> 00:02:32,879
unbirth the dragon

73
00:02:36,790 --> 00:02:35,040
and turn our sights towards hopefully a

74
00:02:37,910 --> 00:02:36,800
couple of more

75
00:02:40,390 --> 00:02:37,920
commercial

76
00:02:42,070 --> 00:02:40,400
cargo resupply flights between now and

77
00:02:43,509 --> 00:02:42,080
the end of the year

78
00:02:45,830 --> 00:02:43,519
so

79
00:02:47,990 --> 00:02:45,840
as i mentioned in parallel to doing all

80
00:02:51,190 --> 00:02:48,000
the science on the spacex

81
00:02:53,589 --> 00:02:51,200
we're about to embark on uh what will be

82
00:02:55,830 --> 00:02:53,599
um a series of evas

83
00:02:58,309 --> 00:02:55,840
starting next week that will stretch out

84
00:03:00,309 --> 00:02:58,319
uh into the first of next year and on

85
00:03:02,309 --> 00:03:00,319
out into the spring

86
00:03:04,470 --> 00:03:02,319
and we'll be doing some things

87
00:03:06,390 --> 00:03:04,480
like like cleaning up some of the the

88
00:03:09,030 --> 00:03:06,400
stuff we still have to clean up from our

89
00:03:10,470 --> 00:03:09,040
past three contingency evas we got the

90
00:03:12,949 --> 00:03:10,480
we got the functionality recovered

91
00:03:14,229 --> 00:03:12,959
during those evas but but we we left

92
00:03:16,869 --> 00:03:14,239
some things out there that we knew that

93
00:03:18,550 --> 00:03:16,879
we wanted to go um put back in proper

94
00:03:20,309 --> 00:03:18,560
order so we'll do that

95
00:03:22,550 --> 00:03:20,319
in addition to that we've had some

96
00:03:24,390 --> 00:03:22,560
failures in our power system so we're

97
00:03:25,830 --> 00:03:24,400
going to go rectify that

98
00:03:28,229 --> 00:03:25,840
also we're going to take advantage while

99
00:03:30,550 --> 00:03:28,239
we're out on on these evas to improve

100
00:03:32,149 --> 00:03:30,560
our overall fault tolerance capability

101
00:03:33,830 --> 00:03:32,159
and by that i mean it gives us an

102
00:03:35,430 --> 00:03:33,840
opportunity to sustain a failure in some

103
00:03:36,390 --> 00:03:35,440
of these critical systems and still be

104
00:03:38,710 --> 00:03:36,400
able to

105
00:03:39,830 --> 00:03:38,720
to function and do the job that station

106
00:03:41,270 --> 00:03:39,840
needs to do

107
00:03:42,949 --> 00:03:41,280
so

108
00:03:44,710 --> 00:03:42,959
that that's going to be part of our near

109
00:03:47,430 --> 00:03:44,720
term plan and when you look it out a

110
00:03:49,270 --> 00:03:47,440
little farther as to how the evas stack

111
00:03:50,550 --> 00:03:49,280
up after the first of the year out into

112
00:03:52,869 --> 00:03:50,560
the spring we're really going to start

113
00:03:54,550 --> 00:03:52,879
this this transformation of the space

114
00:03:55,830 --> 00:03:54,560
station we're going to be we're going to

115
00:03:58,309 --> 00:03:55,840
be doing the things we need to do on

116
00:04:01,509 --> 00:03:58,319
these evas to to prep

117
00:04:03,589 --> 00:04:01,519
for moving moving some modules around

118
00:04:07,190 --> 00:04:03,599
all that is in in preparation for being

119
00:04:09,990 --> 00:04:07,200
able to support some future uh crude uh

120
00:04:12,309 --> 00:04:10,000
vehicles coming to station uh commercial

121
00:04:14,149 --> 00:04:12,319
crew vehicles and so uh we're trying to

122
00:04:15,509 --> 00:04:14,159
get out in front of that and do some

123
00:04:17,030 --> 00:04:15,519
things to put ourselves to position to

124
00:04:18,390 --> 00:04:17,040
be able to do that

125
00:04:19,909 --> 00:04:18,400
so we'll be prepping for movement

126
00:04:21,830 --> 00:04:19,919
modules we'll be installing a new

127
00:04:23,909 --> 00:04:21,840
docking adapter system

128
00:04:25,670 --> 00:04:23,919
so all that will be happening throughout

129
00:04:29,270 --> 00:04:25,680
the next several months onboard the

130
00:04:31,189 --> 00:04:29,280
station as far as our eva plans go

131
00:04:33,270 --> 00:04:31,199
so this is going to put us in the best

132
00:04:35,030 --> 00:04:33,280
position that we need to be in in order

133
00:04:37,830 --> 00:04:35,040
to to sustain

134
00:04:39,830 --> 00:04:37,840
the iss and and keep this outpost uh

135
00:04:42,870 --> 00:04:39,840
functioning and and keep it on track to

136
00:04:45,350 --> 00:04:42,880
be a world-class laboratory that that we

137
00:04:46,710 --> 00:04:45,360
can use to to do research and and

138
00:04:49,510 --> 00:04:46,720
discovery

139
00:04:50,790 --> 00:04:49,520
so so that that's our primary goal so

140
00:04:53,510 --> 00:04:50,800
with that

141
00:04:56,230 --> 00:04:53,520
iss is in good shape the the crew's in

142
00:04:57,670 --> 00:04:56,240
good shape the suits are in good shape

143
00:05:00,469 --> 00:04:57,680
the team's in good shape we're ready to

144
00:05:01,909 --> 00:05:00,479
go do these evas and i'll let scott and

145
00:05:03,430 --> 00:05:01,919
and the folks here talk to you about the

146
00:05:06,230 --> 00:05:03,440
specifics

147
00:05:07,749 --> 00:05:06,240
thank you kenny um so folks i'm scott

148
00:05:10,070 --> 00:05:07,759
stover lead flight director for

149
00:05:12,310 --> 00:05:10,080
spacewalk 27 as rob said we're here to

150
00:05:15,670 --> 00:05:12,320
talk about the two upcoming uh us

151
00:05:19,029 --> 00:05:15,680
spacewalks uh spacewalks 27 and 28.

152
00:05:20,550 --> 00:05:19,039
spacewalk 27 is planned for october 7th

153
00:05:23,110 --> 00:05:20,560
that's a tuesday

154
00:05:26,310 --> 00:05:23,120
and the egress time right now is planned

155
00:05:29,110 --> 00:05:26,320
for about 7 10 a.m central time

156
00:05:32,469 --> 00:05:29,120
spacewalk 28 is planned for wednesday

157
00:05:36,150 --> 00:05:32,479
october 15th again egress is right now

158
00:05:38,310 --> 00:05:36,160
looking to be 7 10 a.m central time

159
00:05:40,550 --> 00:05:38,320
each of the spacewalks are planned to be

160
00:05:42,230 --> 00:05:40,560
six and a half hours in length

161
00:05:45,670 --> 00:05:42,240
both of these spacewalks will use the

162
00:05:47,189 --> 00:05:45,680
u.s space suits and will be egressing

163
00:05:48,950 --> 00:05:47,199
from the u.s

164
00:05:52,469 --> 00:05:48,960
quest airlock

165
00:05:55,830 --> 00:05:52,479
for our crew members spacewalks 27 will

166
00:05:58,070 --> 00:05:55,840
have reid wiseman and alexander gerst as

167
00:05:59,270 --> 00:05:58,080
our eva crew members

168
00:06:01,430 --> 00:05:59,280
for both

169
00:06:03,430 --> 00:06:01,440
wiseman and gerst this will be the first

170
00:06:05,749 --> 00:06:03,440
spacewalk of their careers

171
00:06:07,110 --> 00:06:05,759
however both have had hundreds of hours

172
00:06:08,790 --> 00:06:07,120
in training

173
00:06:11,110 --> 00:06:08,800
both here on the ground in the neutral

174
00:06:13,510 --> 00:06:11,120
buoyancy laboratory pool

175
00:06:17,029 --> 00:06:13,520
but also on orbit and both are ready to

176
00:06:20,469 --> 00:06:17,039
go for the eva

177
00:06:22,390 --> 00:06:20,479
our intravehicular suit crew member will

178
00:06:24,390 --> 00:06:22,400
be barry butch wilmore

179
00:06:26,390 --> 00:06:24,400
and he will also be operating the space

180
00:06:28,870 --> 00:06:26,400
station robotic arm for this uh

181
00:06:31,350 --> 00:06:28,880
spacewalks

182
00:06:34,390 --> 00:06:31,360
alexander gerst happens to be just the

183
00:06:36,950 --> 00:06:34,400
third german spacewalker the first one

184
00:06:39,670 --> 00:06:36,960
was uh thomas ryder and the the second

185
00:06:41,189 --> 00:06:39,680
was han schlegel

186
00:06:44,870 --> 00:06:41,199
um so

187
00:06:48,550 --> 00:06:44,880
for eva 28 or spacewalk 28 the uh

188
00:06:51,189 --> 00:06:48,560
extravehicular crew will be wiseman

189
00:06:52,790 --> 00:06:51,199
and wilmore so this will actually be

190
00:06:53,990 --> 00:06:52,800
wiseman's second

191
00:07:01,189 --> 00:06:54,000
spacewalk

192
00:07:05,670 --> 00:07:03,510
moving on to to give you

193
00:07:08,710 --> 00:07:05,680
a little bit of uh

194
00:07:11,270 --> 00:07:08,720
i will be lead for spacewalk number 27

195
00:07:13,670 --> 00:07:11,280
uh and david korth will be the lead

196
00:07:16,070 --> 00:07:13,680
flight director for spacewalk 28. this

197
00:07:17,990 --> 00:07:16,080
will be his third spacewalk as a lead

198
00:07:19,830 --> 00:07:18,000
flight director

199
00:07:22,309 --> 00:07:19,840
and to give you an overview of spacewalk

200
00:07:24,950 --> 00:07:22,319
27 we'll go through the the objectives

201
00:07:25,909 --> 00:07:24,960
of the spacewalk and and where uh items

202
00:07:27,670 --> 00:07:25,919
are going to

203
00:07:30,550 --> 00:07:27,680
happen the actual work sites around the

204
00:07:32,309 --> 00:07:30,560
space station and then jackie kege our

205
00:07:34,950 --> 00:07:32,319
extra vehicular activity officer will go

206
00:07:37,350 --> 00:07:34,960
into a little bit more detail about that

207
00:07:39,909 --> 00:07:37,360
so for spacewalk 27 our primary

208
00:07:41,749 --> 00:07:39,919
objectives are to move

209
00:07:43,430 --> 00:07:41,759
a degraded pump module which is

210
00:07:45,270 --> 00:07:43,440
currently stowed on

211
00:07:46,790 --> 00:07:45,280
the mobile transporter

212
00:07:49,430 --> 00:07:46,800
and placed that on an

213
00:07:50,869 --> 00:07:49,440
external stowage platform

214
00:07:53,510 --> 00:07:50,879
that pump module

215
00:07:56,469 --> 00:07:53,520
has a failed valve in it that failed

216
00:07:59,510 --> 00:07:56,479
back in december of 2013

217
00:08:02,790 --> 00:07:59,520
and the pump module itself was replaced

218
00:08:05,749 --> 00:08:02,800
on u.s spacewalks number 24 and 25 and

219
00:08:07,830 --> 00:08:05,759
was temporarily stowed uh on the mobile

220
00:08:10,230 --> 00:08:07,840
transporter so we're putting it in its

221
00:08:12,390 --> 00:08:10,240
final stowage location

222
00:08:15,189 --> 00:08:12,400
we are also going to

223
00:08:18,790 --> 00:08:15,199
replace a camera light

224
00:08:20,710 --> 00:08:18,800
that is on the starboard side of the lab

225
00:08:23,029 --> 00:08:20,720
the destiny module

226
00:08:24,629 --> 00:08:23,039
that light has one of two bulbs

227
00:08:26,790 --> 00:08:24,639
currently failed in it and it's one of

228
00:08:27,990 --> 00:08:26,800
our primary lights that we use

229
00:08:29,830 --> 00:08:28,000
for

230
00:08:31,749 --> 00:08:29,840
the visiting vehicles when they arrive

231
00:08:33,110 --> 00:08:31,759
and also for supporting external

232
00:08:34,310 --> 00:08:33,120
robotics

233
00:08:36,630 --> 00:08:34,320
so we want to go ahead and replace that

234
00:08:38,149 --> 00:08:36,640
light before the second bulb fails

235
00:08:40,469 --> 00:08:38,159
we will also be installing what is

236
00:08:41,670 --> 00:08:40,479
called the mobile transporter relay

237
00:08:44,470 --> 00:08:41,680
assembly

238
00:08:46,550 --> 00:08:44,480
this is a new capability that we'll have

239
00:08:48,630 --> 00:08:46,560
is hopefully you you know the the mobile

240
00:08:50,150 --> 00:08:48,640
transporter is a

241
00:08:52,230 --> 00:08:50,160
vehicle that actually moves up and down

242
00:08:53,910 --> 00:08:52,240
the length of the space station truss

243
00:08:56,389 --> 00:08:53,920
and has multiple work sites that it can

244
00:08:59,030 --> 00:08:56,399
plug in to get power uh if for some

245
00:09:00,470 --> 00:08:59,040
reason we couldn't give power to that

246
00:09:02,070 --> 00:09:00,480
mobile transporter at one of those work

247
00:09:04,470 --> 00:09:02,080
sites this new

248
00:09:05,350 --> 00:09:04,480
mtra allows us to provide keep a live

249
00:09:06,949 --> 00:09:05,360
power

250
00:09:09,030 --> 00:09:06,959
and we'd be able to make sure there's no

251
00:09:12,470 --> 00:09:09,040
hardware damage to the mobile

252
00:09:13,990 --> 00:09:12,480
transporter or anything attached to it

253
00:09:15,829 --> 00:09:14,000
when we go to look at where is all this

254
00:09:17,269 --> 00:09:15,839
happening luckily we're all pretty

255
00:09:19,430 --> 00:09:17,279
centered up in the middle of the space

256
00:09:20,550 --> 00:09:19,440
station we don't have to send the ev

257
00:09:22,630 --> 00:09:20,560
crew members

258
00:09:24,470 --> 00:09:22,640
far away from the airlock the mobile

259
00:09:26,230 --> 00:09:24,480
transporter itself will be at work site

260
00:09:28,550 --> 00:09:26,240
four which is actually in the very

261
00:09:31,110 --> 00:09:28,560
center of the s0 truss

262
00:09:33,030 --> 00:09:31,120
that's where the degraded pump module is

263
00:09:35,430 --> 00:09:33,040
currently located and we'll be moving

264
00:09:37,269 --> 00:09:35,440
that over to the external stowage

265
00:09:39,750 --> 00:09:37,279
platform number two

266
00:09:41,910 --> 00:09:39,760
which is located on the starboard side

267
00:09:43,829 --> 00:09:41,920
of the lab just in front of the airlock

268
00:09:46,550 --> 00:09:43,839
itself

269
00:09:48,870 --> 00:09:46,560
the camera light that we're going to be

270
00:09:51,670 --> 00:09:48,880
replacing is also on the starboard side

271
00:09:53,590 --> 00:09:51,680
of the the lab and not very far away

272
00:09:55,509 --> 00:09:53,600
from esp2

273
00:09:58,550 --> 00:09:55,519
and finally the mobile transporter relay

274
00:10:00,790 --> 00:09:58,560
assembly that is being installed up on

275
00:10:04,470 --> 00:10:00,800
the mobile transporter once again at the

276
00:10:07,670 --> 00:10:04,480
center of the s0 truss

277
00:10:09,750 --> 00:10:07,680
so to give you a quick overview of the

278
00:10:12,470 --> 00:10:09,760
priorities and everything for spacewalk

279
00:10:15,350 --> 00:10:12,480
number 28

280
00:10:16,630 --> 00:10:15,360
we have the the first and most important

281
00:10:19,670 --> 00:10:16,640
activity we have we're going to replace

282
00:10:22,870 --> 00:10:19,680
sequential shunt unit 3a

283
00:10:25,030 --> 00:10:22,880
this box provides regulated power from

284
00:10:27,509 --> 00:10:25,040
solar array number 3a

285
00:10:30,150 --> 00:10:27,519
this box failed

286
00:10:31,990 --> 00:10:30,160
back in may of 2014.

287
00:10:34,790 --> 00:10:32,000
it really is no impact to any of the

288
00:10:36,550 --> 00:10:34,800
downstream users of that power because

289
00:10:40,870 --> 00:10:36,560
all of those loads have been transferred

290
00:10:43,230 --> 00:10:40,880
to the power channel 3 bravo

291
00:10:45,829 --> 00:10:43,240
that said by replacing

292
00:10:47,509 --> 00:10:45,839
ssu3a that will allow us to have more

293
00:10:49,030 --> 00:10:47,519
flexibility and redundancy in the

294
00:10:50,069 --> 00:10:49,040
primary power system of the space

295
00:10:51,990 --> 00:10:50,079
station

296
00:10:53,350 --> 00:10:52,000
and ultimately we'll make sure that we

297
00:10:55,750 --> 00:10:53,360
can have enough power for all the

298
00:10:57,190 --> 00:10:55,760
science that we want to go do

299
00:10:59,430 --> 00:10:57,200
the other items that we will be

300
00:11:01,750 --> 00:10:59,440
performing on spacewalk 28 are all in

301
00:11:04,310 --> 00:11:01,760
preparation for the relocation of the

302
00:11:05,990 --> 00:11:04,320
permanent multi-purpose module

303
00:11:07,829 --> 00:11:06,000
the pmm

304
00:11:09,750 --> 00:11:07,839
as kenny mentioned we are getting ready

305
00:11:11,990 --> 00:11:09,760
to do some reconfigurations of the space

306
00:11:15,350 --> 00:11:12,000
station in preparation for commercial

307
00:11:17,910 --> 00:11:15,360
crew capabilities and to give us another

308
00:11:19,190 --> 00:11:17,920
birthing port for our commercial cargo

309
00:11:19,990 --> 00:11:19,200
vehicles

310
00:11:21,670 --> 00:11:20,000
so

311
00:11:24,550 --> 00:11:21,680
in order for us to be able to

312
00:11:26,870 --> 00:11:24,560
move the permanent multi-purpose module

313
00:11:29,269 --> 00:11:26,880
we need to relocate

314
00:11:31,030 --> 00:11:29,279
multiple components that are outside the

315
00:11:33,269 --> 00:11:31,040
first one that we're going to touch is

316
00:11:36,550 --> 00:11:33,279
the camera port number seven that's

317
00:11:38,389 --> 00:11:36,560
currently located on the p1 truss

318
00:11:40,630 --> 00:11:38,399
and we're going to actually not only

319
00:11:42,949 --> 00:11:40,640
just move this camera we're going to

320
00:11:45,829 --> 00:11:42,959
replace it with a new one the current

321
00:11:47,110 --> 00:11:45,839
camera has a stuck zoom capability uh

322
00:11:49,430 --> 00:11:47,120
and although

323
00:11:51,750 --> 00:11:49,440
it's usable in many ways we really do

324
00:11:53,910 --> 00:11:51,760
want to recover that capability so we'll

325
00:11:56,790 --> 00:11:53,920
we'll be moving that camera from the

326
00:11:59,430 --> 00:11:56,800
bottom of the port 1 truss and placing

327
00:12:01,030 --> 00:11:59,440
it up on top of the port 1 truss with a

328
00:12:03,110 --> 00:12:01,040
brand new camera

329
00:12:04,550 --> 00:12:03,120
we're also going to move what's called

330
00:12:06,230 --> 00:12:04,560
an adjustable

331
00:12:08,470 --> 00:12:06,240
portable foot restraint and tool

332
00:12:10,629 --> 00:12:08,480
stanchion that also is currently located

333
00:12:12,069 --> 00:12:10,639
on the bottom of the port 1 trust and

334
00:12:12,949 --> 00:12:12,079
we're just going to move it out of the

335
00:12:16,629 --> 00:12:12,959
way

336
00:12:18,470 --> 00:12:16,639
and place it up on the s0 truss

337
00:12:20,230 --> 00:12:18,480
and the

338
00:12:23,590 --> 00:12:20,240
one other thing that we're going to move

339
00:12:25,350 --> 00:12:23,600
is a wireless external television

340
00:12:27,110 --> 00:12:25,360
camera assembly

341
00:12:29,910 --> 00:12:27,120
or antenna assembly

342
00:12:32,230 --> 00:12:29,920
that receives all the video signals that

343
00:12:33,190 --> 00:12:32,240
you see from our space walking crew

344
00:12:34,790 --> 00:12:33,200
members

345
00:12:36,389 --> 00:12:34,800
we're going to move that from its

346
00:12:38,870 --> 00:12:36,399
current location on top of the port 1

347
00:12:40,790 --> 00:12:38,880
truss out and actually put it on top of

348
00:12:42,230 --> 00:12:40,800
the node 2 module

349
00:12:44,310 --> 00:12:42,240
again all of this is really in

350
00:12:46,069 --> 00:12:44,320
preparations for

351
00:12:47,750 --> 00:12:46,079
the permanent multi-purpose module

352
00:12:49,910 --> 00:12:47,760
relocation which

353
00:12:52,710 --> 00:12:49,920
currently is scheduled sometime over the

354
00:12:55,350 --> 00:12:52,720
summer of next year

355
00:12:57,269 --> 00:12:55,360
so with that i'm going to now pass over

356
00:12:59,350 --> 00:12:57,279
to jackie kege who is our lead extra

357
00:13:01,030 --> 00:12:59,360
vehicular activity officer for spacewalk

358
00:13:03,030 --> 00:13:01,040
number 27.

359
00:13:06,629 --> 00:13:03,040
hi i'm jacqueline cagey the lead eva

360
00:13:08,790 --> 00:13:06,639
space work officer for usc va 27

361
00:13:11,750 --> 00:13:08,800
as scott mentioned the spacewalk will be

362
00:13:14,870 --> 00:13:11,760
performed by reed wiseman as ev1

363
00:13:15,910 --> 00:13:14,880
and alexander gersht as ev2 with butch

364
00:13:18,790 --> 00:13:15,920
wilmore

365
00:13:20,710 --> 00:13:18,800
providing our iv support and our robotic

366
00:13:22,310 --> 00:13:20,720
arm operations

367
00:13:24,069 --> 00:13:22,320
wiseman and gersch have been training in

368
00:13:25,750 --> 00:13:24,079
a long time for this

369
00:13:28,069 --> 00:13:25,760
eva we

370
00:13:30,710 --> 00:13:28,079
were able to prepare them in the mbl

371
00:13:33,350 --> 00:13:30,720
prior to launch

372
00:13:35,990 --> 00:13:33,360
we did simulate this entire eva back in

373
00:13:37,590 --> 00:13:36,000
march together so

374
00:13:40,949 --> 00:13:37,600
they are

375
00:13:43,110 --> 00:13:40,959
ready to to perform it next week

376
00:13:46,230 --> 00:13:43,120
wiseman will be extra vehicular crew

377
00:13:48,790 --> 00:13:46,240
member number ev1 he will be wearing red

378
00:13:50,870 --> 00:13:48,800
stripes and first will be crew member

379
00:13:53,430 --> 00:13:50,880
number two ev2 wearing a plain white

380
00:13:57,750 --> 00:13:54,629
they will begin the spacewalk

381
00:14:00,310 --> 00:13:57,760
preparations about 2 15 am central time

382
00:14:02,230 --> 00:14:00,320
and scheduled to begin their in-suit

383
00:14:04,629 --> 00:14:02,240
light exercise or aisle pre-breathe

384
00:14:06,870 --> 00:14:04,639
protocol about 4 15.

385
00:14:08,550 --> 00:14:06,880
aisle stands for in-suit light exercise

386
00:14:11,110 --> 00:14:08,560
it's a pre-breathe protocol that we

387
00:14:14,150 --> 00:14:11,120
started in increment 27

388
00:14:16,629 --> 00:14:14,160
this protocol we don the spacesuits and

389
00:14:19,030 --> 00:14:16,639
then exercise very lightly for about 15

390
00:14:21,110 --> 00:14:19,040
minutes with rest breaks in between

391
00:14:23,110 --> 00:14:21,120
the exercise equates to just slightly

392
00:14:26,230 --> 00:14:23,120
moving your arms and legs to get the

393
00:14:28,310 --> 00:14:26,240
nitrogen out of your system

394
00:14:30,790 --> 00:14:28,320
egress from the u.s airlock will be at 7

395
00:14:33,750 --> 00:14:30,800
15 a.m central time

396
00:14:37,189 --> 00:14:33,760
and with that i will begin the video to

397
00:14:42,550 --> 00:14:39,750
usc va 27 will start from the quest

398
00:14:48,790 --> 00:14:42,560
airlock reed wiseman ev1 wearing a suit

399
00:14:56,470 --> 00:14:51,590
alexander gersht ev2 wearing a plain

400
00:15:01,829 --> 00:14:59,750
and then after completing buddy checks

401
00:15:04,550 --> 00:15:01,839
alex will head to the starboard cedar

402
00:15:11,670 --> 00:15:04,560
cart to temp stow the mtra bags for

403
00:15:20,790 --> 00:15:14,550
reed will translate to esp2 to prepare

404
00:15:20,800 --> 00:15:26,629
he will temp stow bags

405
00:15:39,189 --> 00:15:28,470
and then open the thermal blanket to

406
00:15:43,670 --> 00:15:40,949
meanwhile alex will translate to the

407
00:15:55,749 --> 00:15:43,680
port cedar cart to retrieve the apfr or

408
00:15:59,990 --> 00:15:57,990
which he will translate to the ssrms

409
00:16:00,829 --> 00:16:00,000
installation location

410
00:16:11,430 --> 00:16:00,839
on

411
00:16:14,230 --> 00:16:11,440
the arm

412
00:16:22,069 --> 00:16:14,240
swap his safety tether

413
00:16:35,509 --> 00:16:23,990
at this point reed will translate to the

414
00:16:55,749 --> 00:16:37,910
and move them to the mtra worksite to

415
00:17:03,030 --> 00:16:58,310
there are two bags one contains the mtra

416
00:17:09,270 --> 00:17:04,789
and the second bag contains the four

417
00:17:13,669 --> 00:17:12,710
then ev1 will translate to ev2's safety

418
00:17:21,029 --> 00:17:13,679
tether

419
00:17:25,110 --> 00:17:22,949
alex rides the arm which is flown by

420
00:17:26,789 --> 00:17:25,120
butch wilmore to the poa to retrieve the

421
00:17:28,710 --> 00:17:26,799
pump munchl

422
00:17:30,230 --> 00:17:28,720
the poa is a robotically controlled

423
00:17:37,990 --> 00:17:30,240
stowage site that we placed the pump

424
00:17:43,430 --> 00:17:39,830
during the arm maneuver alex will rotate

425
00:17:46,789 --> 00:17:43,440
the pump module 180 degrees to get it to

426
00:17:48,390 --> 00:17:46,799
the correct installation orientation

427
00:17:56,870 --> 00:17:48,400
and please note that the arm maneuver

428
00:18:01,750 --> 00:17:59,270
reed will help guide butch and alex to

429
00:18:11,350 --> 00:18:01,760
install the pump module partially onto

430
00:18:15,909 --> 00:18:13,029
he will then remove the adjustable

431
00:18:23,430 --> 00:18:15,919
grapple bar or agb from the pump module

432
00:18:28,070 --> 00:18:25,350
and the crew will complete the final

433
00:18:29,990 --> 00:18:28,080
installation of the pump module and then

434
00:18:36,630 --> 00:18:30,000
we'll use the pgt to drive the four

435
00:18:41,350 --> 00:18:38,070
at this point the ev crew worked

436
00:18:46,789 --> 00:18:41,360
together to stow the agb on a spare oru

437
00:18:51,830 --> 00:18:49,990
and the agb is the method that

438
00:18:54,789 --> 00:18:51,840
was able to attach the pump module to

439
00:19:04,230 --> 00:18:54,799
the poa for that long

440
00:19:08,549 --> 00:19:06,150
and while the arm flies alex tore this

441
00:19:10,870 --> 00:19:08,559
next task reed will clean up the pump

442
00:19:18,789 --> 00:19:10,880
module work site including closing the

443
00:19:27,909 --> 00:19:21,190
alex is flown to camera port 13 which is

444
00:19:33,270 --> 00:19:29,909
you will first lock the camera pan and

445
00:19:33,280 --> 00:19:47,350
and then remove the failed light

446
00:19:57,750 --> 00:19:49,669
ev2 will retrieve the spare light from

447
00:20:06,870 --> 00:19:59,750
install it with a single bolt and the

448
00:20:13,590 --> 00:20:09,270
alex will then retrieve the handling aid

449
00:20:19,190 --> 00:20:15,430
and then he will unlock the pan and tilt

450
00:20:21,430 --> 00:20:19,200
unit prior to you leaving the work site

451
00:20:28,789 --> 00:20:21,440
during this time ev1 returns the pump

452
00:20:46,230 --> 00:20:31,350
and proceeds to translate to the mtra

453
00:20:52,549 --> 00:20:48,789
the mtra worksite is on the zenith side

454
00:20:59,110 --> 00:20:56,789
when reed begin gets into position

455
00:21:02,470 --> 00:20:59,120
he will remove the dead face connector

456
00:21:05,990 --> 00:21:02,480
that has protected the camera port since

457
00:21:14,310 --> 00:21:08,870
then he will install the empty array

458
00:21:17,430 --> 00:21:16,149
reed will gather the red yellow cable

459
00:21:21,270 --> 00:21:17,440
set

460
00:21:25,830 --> 00:21:21,280
and attach one end to the mtra box

461
00:21:27,830 --> 00:21:25,840
then route and mate the yellow connector

462
00:21:29,029 --> 00:21:27,840
and continue down the port side of the

463
00:21:31,590 --> 00:21:29,039
mt

464
00:21:44,149 --> 00:21:31,600
to the nadir empty location to meet the

465
00:21:51,110 --> 00:21:46,950
will fly back to esp2 to clean up the

466
00:21:51,120 --> 00:21:57,669
including a safety tether swap

467
00:21:57,679 --> 00:22:07,430
and removal of the apfr

468
00:22:14,390 --> 00:22:10,630
he then releases the ssrms from support

469
00:22:17,510 --> 00:22:16,070
and he will translate back to the

470
00:22:19,909 --> 00:22:17,520
airlock

471
00:22:24,310 --> 00:22:19,919
to stow the failed light inside the

472
00:22:35,669 --> 00:22:27,510
alex then translate to the mtra worksite

473
00:22:41,990 --> 00:22:38,310
ev2 will work the starboard side of the

474
00:22:48,310 --> 00:22:42,000
mtra where ev1 worked the port

475
00:22:48,320 --> 00:22:56,470
and make the connectors to the mtra

476
00:23:00,230 --> 00:22:57,909
you will route the cables down the

477
00:23:06,710 --> 00:23:00,240
starboard side of the mt

478
00:23:13,350 --> 00:23:08,870
and then hand off the blue connection

479
00:23:17,830 --> 00:23:15,110
the crew will then translate back to the

480
00:23:20,310 --> 00:23:17,840
zenith side of the mt making to sure to

481
00:23:28,149 --> 00:23:20,320
secure all their wire ties to keep the

482
00:23:30,870 --> 00:23:29,909
at this point they will clean up their

483
00:23:36,630 --> 00:23:30,880
bags

484
00:23:50,870 --> 00:23:39,190
they will ingress the airlock completing

485
00:23:55,350 --> 00:23:53,909
although we have not allotted for extra

486
00:23:58,549 --> 00:23:55,360
tasks beyond

487
00:23:59,990 --> 00:23:58,559
the mtra we have prepared some in case

488
00:24:02,470 --> 00:24:00,000
the crew does have extra time while

489
00:24:04,390 --> 00:24:02,480
they're outside these get ahead tasks

490
00:24:08,070 --> 00:24:04,400
are called

491
00:24:09,510 --> 00:24:08,080
our first two priorities would be

492
00:24:11,269 --> 00:24:09,520
actually two of the tests that keith

493
00:24:13,510 --> 00:24:11,279
will talk about in a couple minutes for

494
00:24:16,870 --> 00:24:13,520
his eva would be trying to get some of

495
00:24:18,470 --> 00:24:16,880
those that work done off of the eva 28

496
00:24:20,789 --> 00:24:18,480
before continuing

497
00:24:21,990 --> 00:24:20,799
on to some get-aheads that would

498
00:24:24,390 --> 00:24:22,000
help

499
00:24:27,510 --> 00:24:24,400
reconfigure the cedar carts deploy the

500
00:24:30,310 --> 00:24:27,520
mlm ethernet cable or gather some bags

501
00:24:32,549 --> 00:24:30,320
that we left outside on previous evas

502
00:24:35,110 --> 00:24:32,559
now i'll pass over to keith johnson who

503
00:24:38,149 --> 00:24:35,120

scott mentioned that the

523
00:25:23,190 --> 00:25:18,799
ssu-3a is our critical task on this eva

524
00:25:25,269 --> 00:25:23,200
and in order to change out this ssu

525
00:25:28,070 --> 00:25:25,279
it would be receiving full power in the

526
00:25:30,470 --> 00:25:28,080
daylight pass of the solar a so as an

527
00:25:33,029 --> 00:25:30,480
inhibit we'll be changing out that

528
00:25:35,269 --> 00:25:33,039
during an eclipse a night pass

529
00:25:37,350 --> 00:25:35,279
at this particular beta angle on october

530
00:25:40,630 --> 00:25:37,360
15th we have a little over 30 minutes to

531
00:25:42,470 --> 00:25:40,640
get this box removed and replaced with

532
00:25:43,350 --> 00:25:42,480
the replacement unit

533
00:25:45,750 --> 00:25:43,360
um

534
00:25:48,630 --> 00:25:45,760
let's see uh we will be starting eva at

535
00:25:54,950 --> 00:25:48,640
about 7 20 in the morning on october

536
00:26:00,230 --> 00:25:57,750
okay as i mentioned uh reid wiseman will

537
00:26:02,710 --> 00:26:00,240
be ev1 he'll be the one with the red

538
00:26:05,909 --> 00:26:02,720
stripes coming out of the airlock first

539
00:26:08,950 --> 00:26:05,919
he'll be followed by uh barry butch

540
00:26:11,110 --> 00:26:08,960

00:26:13,909 --> 00:26:11,120
they'll hand out the spare sequential

542
00:26:16,549 --> 00:26:13,919
shunt unit in an orbital replacement

543
00:26:18,630 --> 00:26:16,559
unit bag

544
00:26:22,870 --> 00:26:18,640
reed will assist butch in translation up

545
00:26:30,630 --> 00:26:24,950
which will start out first along face

546
00:26:40,390 --> 00:26:32,470
he'll drop a green hook from his safety

547
00:26:43,190 --> 00:26:41,669
meanwhile

548
00:26:47,510 --> 00:26:43,200
reid will climb up the crew and

549
00:26:51,669 --> 00:26:49,750
he'll transfer his crew lock bag with

550
00:26:56,230 --> 00:26:51,679
his tools in it onto an articulating

551
00:27:00,149 --> 00:26:58,230
he'll release that bundle

552
00:27:03,190 --> 00:27:00,159
and he'll stow it on his body restraint

553
00:27:05,110 --> 00:27:03,200
tether or brt

554
00:27:07,510 --> 00:27:05,120
reid will join butch along the starboard

00:27:09,830 --> 00:27:07,520
face one truss

556
00:27:11,669 --> 00:27:09,840
or he'll drop his green hook and that

557
00:27:15,110 --> 00:27:11,679
allows them to go farther out on the

558
00:27:19,269 --> 00:27:17,510
butch and reed will continue translating

559
00:27:24,630 --> 00:27:19,279
starboard

560
00:27:24,640 --> 00:27:29,990
out to the 3a solar array

561
00:27:33,669 --> 00:27:32,070
butch will stow the oru bag holding the

562
00:27:38,710 --> 00:27:33,679
spare ssu

563
00:27:43,750 --> 00:27:41,110
reed will join butch and install the

564
00:27:47,750 --> 00:27:43,760
apfr with the crew lock bag

565
00:27:49,830 --> 00:27:47,760
and a worksite interface or with socket

566
00:27:51,430 --> 00:27:49,840
he'll remove the crew lock bag

567
00:27:55,669 --> 00:27:51,440
with the tools and stow it at the

568
00:28:05,190 --> 00:27:58,230
it'll ingress the apfr in preparation

569
00:28:09,590 --> 00:28:07,430
during the day pass prior to the eclipse

570
00:28:11,029 --> 00:28:09,600
he'll install a handling aid called a

571
00:28:13,029 --> 00:28:11,039
scoop

572
00:28:15,430 --> 00:28:13,039
on the failed ssu

573
00:28:16,950 --> 00:28:15,440
and he'll loosen the bolt

574
00:28:23,269 --> 00:28:16,960
in preparation for driving it all the

575
00:28:27,190 --> 00:28:25,269
in eclipse he'll remove the the failed

576
00:28:29,750 --> 00:28:27,200
unit

577
00:28:30,870 --> 00:28:29,760
and butch will prepare the replacement

578
00:28:33,750 --> 00:28:30,880
unit

579
00:28:35,669 --> 00:28:33,760
hand it over to reed

580
00:28:37,750 --> 00:28:35,679
it'll present the electrical connector

581
00:28:39,430 --> 00:28:37,760
side of the ssu to butch

582
00:28:42,389 --> 00:28:39,440
to inspect for

583
00:28:44,470 --> 00:28:42,399
debris damage bent pins or things that

584
00:28:47,350 --> 00:28:44,480
could prevent it from being installed

585
00:28:50,310 --> 00:28:47,360
and here's an image of the business side

586
00:28:50,320 --> 00:28:55,430
reed will rotate the ssu into position

587
00:29:01,510 --> 00:28:57,350
and you'll drive the bolt while butch

588
00:29:05,830 --> 00:29:03,510
once the ssu is installed the crew will

589
00:29:09,750 --> 00:29:05,840
notify the ground to start testing it

590
00:29:15,029 --> 00:29:12,149
and he'll hand butch the failed ssu to

591
00:29:17,269 --> 00:29:15,039
put in the oru bag

592
00:29:23,430 --> 00:29:17,279
which will put the bag in the s the ssu

593
00:29:29,510 --> 00:29:26,470
reed will egress the apfr

594
00:29:35,269 --> 00:29:29,520
he'll put the crew lock bag on the apfr

595
00:29:38,870 --> 00:29:37,110
reed and butch will head back inboard

596
00:29:51,269 --> 00:29:38,880
following these their safety tethers

597
00:29:55,350 --> 00:29:53,430
we'll stop along the way to pick up

598
00:29:56,710 --> 00:29:55,360
the green hooks that they dropped

599
00:30:05,830 --> 00:29:56,720
on their way out and then they'll

600
00:30:10,470 --> 00:30:08,630
readable stow is apfr

601
00:30:17,430 --> 00:30:10,480
and he'll retrieve the crew lock bag off

602
00:30:22,070 --> 00:30:19,830
and butch will go to the airlock and

603
00:30:26,310 --> 00:30:22,080
he'll stow the failed ssu and he'll

604
00:30:31,350 --> 00:30:28,310
from there he'll head towards camera

605
00:30:45,269 --> 00:30:31,360
port 7 or cp7 as we call it on the port

606
00:30:51,909 --> 00:30:49,510
once he's there he'll stow his oru bag

607
00:30:54,070 --> 00:30:51,919
meanwhile uh readable butch will join

608
00:30:58,070 --> 00:30:54,080
butch at cp7 translating a little bit

609
00:31:06,950 --> 00:30:59,990
and that'll help deconflict their safety

610
00:31:17,990 --> 00:31:09,350
which will temporarily stow his smaller

611
00:31:23,029 --> 00:31:19,509
the two of them will move over to

612
00:31:26,549 --> 00:31:23,039
release the apfr and tool stanchion

613
00:31:28,230 --> 00:31:26,559
and they'll shepard it inboard

614
00:31:30,710 --> 00:31:28,240
that'll get it out of the way for the

615
00:31:36,070 --> 00:31:30,720
permanent multi-purpose module or pmm

616
00:31:36,080 --> 00:31:40,470
reading butch will return to cp7

617
00:31:51,110 --> 00:31:42,389
reed will remove a crew lock bag from

618
00:31:58,070 --> 00:31:53,909
butch will release the bolts on the cp7

619
00:32:01,509 --> 00:32:00,630
we'll hand butch a scoop

620
00:32:03,269 --> 00:32:01,519
and then

621
00:32:05,110 --> 00:32:03,279
butch will install it

622
00:32:12,149 --> 00:32:05,120
and he'll remove the camera group and

623
00:32:18,950 --> 00:32:14,470
from there reed will temporarily stow

624
00:32:23,190 --> 00:32:21,190
butch and reed will disconnect and stow

625
00:32:24,710 --> 00:32:23,200
three electrical connectors

626
00:32:27,110 --> 00:32:24,720
from the stanchion

627
00:32:35,110 --> 00:32:27,120
and install a small oru bag as a

628
00:32:39,190 --> 00:32:37,590
they'll release the stanchion bolt

629
00:32:47,029 --> 00:32:39,200
and reed will hand the stanchion to

630
00:32:50,710 --> 00:32:49,269
from there butch will head forward on

631
00:32:54,149 --> 00:32:50,720
iss

632
00:33:02,789 --> 00:32:54,159
to the zenith aft end of node 2

633
00:33:08,070 --> 00:33:04,230
which will install the stanchion at

634
00:33:20,549 --> 00:33:10,950
and remove the oru bag

635
00:33:25,269 --> 00:33:22,950
meanwhile

636
00:33:27,269 --> 00:33:25,279
reed will translate port zenith to

637
00:33:40,149 --> 00:33:27,279
camera port 8

638
00:33:44,230 --> 00:33:42,230
he'll release two outer and one center

639
00:33:47,990 --> 00:33:44,240
bolt of the wireless video system

640
00:33:56,630 --> 00:33:48,000
external transceiver assembly or weta

641
00:34:06,149 --> 00:33:58,549
i'll remove the whole unit and put it on

642
00:34:22,149 --> 00:34:08,069
and then i'll translate out

643
00:34:22,159 --> 00:34:30,550
you'll hand the weta off to butch

644
00:34:35,990 --> 00:34:33,270
from there reed will retrieve the failed

645
00:34:39,669 --> 00:34:36,000
camera group from its temporary stowage

646
00:34:39,679 --> 00:34:45,349
and will translate to the airlock

647
00:34:49,589 --> 00:34:47,030
the airlock will exchange the failed

648
00:34:59,910 --> 00:34:49,599
camera group with a replacement unit in

649
00:35:05,349 --> 00:35:02,790
it'll translate back to the port truss

650
00:35:06,950 --> 00:35:05,359
and up to cp8

651
00:35:24,230 --> 00:35:06,960
we removed

652
00:35:32,870 --> 00:35:25,430
he'll remove

653
00:35:32,880 --> 00:35:40,069
and install it on the camera stanchion

654
00:35:48,150 --> 00:35:42,550
he'll remove the scoop handling aid

655
00:35:53,910 --> 00:35:49,589
he'll check the alignment of the camera

656
00:35:57,030 --> 00:35:55,670
and retrieve his oru bag and put it on

657
00:35:58,550 --> 00:35:57,040
his brt

658
00:36:00,790 --> 00:35:58,560
during that time butch will be

659
00:36:03,990 --> 00:36:00,800
installing the weta on the cp-11

660
00:36:07,109 --> 00:36:06,069
it'll remove the scoop stow it in the

661
00:36:08,630 --> 00:36:07,119
bag

662
00:36:11,990 --> 00:36:08,640
and he'll drive the center and outer

663
00:36:16,550 --> 00:36:13,510
then he'll connect the electrical

664
00:36:25,510 --> 00:36:19,270
and retrieve his oru bag

665
00:36:29,190 --> 00:36:27,190
at this point both crew members will

666
00:36:30,230 --> 00:36:29,200
return to the airlock they'll stow their

667
00:36:32,790 --> 00:36:30,240
bags

668
00:36:36,310 --> 00:36:32,800
and ingress butch going in first

669
00:36:36,320 --> 00:36:47,430
and that will complete uscva 28.

670
00:36:49,589 --> 00:36:48,230
so

671
00:36:51,990 --> 00:36:49,599
we expect

672
00:36:53,349 --> 00:36:52,000
the evas to last about six and a half

673
00:36:55,990 --> 00:36:53,359
hours

674
00:36:59,030 --> 00:36:56,000
if for some reason things go very well

675
00:37:01,829 --> 00:36:59,040
on uscva27 as jackie mentioned and they

676
00:37:04,069 --> 00:37:01,839
get several of our tasks completed early

677
00:37:04,870 --> 00:37:04,079
we have a list of of get ahead tasks

678
00:37:07,510 --> 00:37:04,880
that

679
00:37:09,349 --> 00:37:07,520
we can start

680
00:37:11,910 --> 00:37:09,359
one of the the tasks that we have on our

681
00:37:15,190 --> 00:37:11,920
list as a get ahead is releasing battery

682
00:37:18,310 --> 00:37:15,200
bolts on the s4 and s6 truss in

683
00:37:20,150 --> 00:37:18,320
preparation for those battery rnr's um

684
00:37:22,790 --> 00:37:20,160
in in years to come

685
00:37:25,430 --> 00:37:22,800
we also can retrieve the cp9

686
00:37:27,910 --> 00:37:25,440
light that's outside

687
00:37:30,150 --> 00:37:27,920
jackie mentioned the the bags that could

688
00:37:32,630 --> 00:37:30,160
be brought inside we also have

689
00:37:34,470 --> 00:37:32,640
the mlm ethernet cable

690
00:37:36,790 --> 00:37:34,480
routing that we could complete

691
00:37:38,150 --> 00:37:36,800
out onto pma1

692
00:37:40,150 --> 00:37:38,160
and we also have the cedar cart

693
00:37:41,270 --> 00:37:40,160
reconfigurations as part of our get

694
00:37:43,589 --> 00:37:41,280
ahead list

695
00:37:45,670 --> 00:37:43,599
and an airlock handrail clamp to cover

696
00:37:48,069 --> 00:37:45,680
up an mmod strike

697
00:37:50,630 --> 00:37:48,079
and that's all i have

698
00:37:52,950 --> 00:37:50,640
okay thanks keith uh time for questions

699
00:37:54,870 --> 00:37:52,960
and we'll take them here at jsc and on

700
00:37:57,190 --> 00:37:54,880
our phone bridge and we'll start off

701
00:37:59,990 --> 00:37:57,200
over here with mark caro mark

702
00:38:02,230 --> 00:38:00,000
uh thank you mark caro for aviation week

703
00:38:04,870 --> 00:38:02,240
i had a question and a follow-up i

704
00:38:07,829 --> 00:38:04,880
wonder if you might uh go back to the

705
00:38:09,270 --> 00:38:07,839
battery fuse issue that sort of

706
00:38:10,470 --> 00:38:09,280
forced the delay

707
00:38:12,950 --> 00:38:10,480
uh from

708
00:38:15,030 --> 00:38:12,960
resuming the maintenance space walks in

709
00:38:16,950 --> 00:38:15,040
in august and i guess where i'm going

710
00:38:19,670 --> 00:38:16,960
with that is to to understand that that

711
00:38:21,750 --> 00:38:19,680
was a generic problem or or

712
00:38:25,430 --> 00:38:21,760
what you know what you needed to do to

713
00:38:26,790 --> 00:38:25,440
resolve that how it arose and

714
00:38:28,790 --> 00:38:26,800
don't have a fault

715
00:38:31,510 --> 00:38:28,800
well let's see the the issue was with

716
00:38:32,470 --> 00:38:31,520
our our long life batteries

717
00:38:35,030 --> 00:38:32,480
there was a

718
00:38:36,790 --> 00:38:35,040
discovery that was made

719
00:38:39,190 --> 00:38:36,800
when looking back at the testing and the

720
00:38:40,470 --> 00:38:39,200
way the batteries were tested

721
00:38:42,950 --> 00:38:40,480
that

722
00:38:44,230 --> 00:38:42,960
generically anytime you you get ready to

723
00:38:45,670 --> 00:38:44,240
fly a set of batteries we go through

724
00:38:46,470 --> 00:38:45,680
what we call a series of acceptance

725
00:38:48,630 --> 00:38:46,480
tests

726
00:38:50,069 --> 00:38:48,640
for those batteries and

727
00:38:51,510 --> 00:38:50,079
we put them through a number of

728
00:38:53,750 --> 00:38:51,520
different cycles

729
00:38:55,349 --> 00:38:53,760
and for the batteries

730
00:38:57,430 --> 00:38:55,359
they discovered some on the ground here

731
00:38:59,270 --> 00:38:57,440
in their testing that their test plan

732
00:39:01,589 --> 00:38:59,280
called out more cycles

733
00:39:02,710 --> 00:39:01,599
than than what was required

734
00:39:04,710 --> 00:39:02,720
and so

735
00:39:07,109 --> 00:39:04,720
at the time we looked at it hard and

736
00:39:09,190 --> 00:39:07,119
said you know do we want to continue

737
00:39:10,870 --> 00:39:09,200
with the batteries we have on board

738
00:39:12,230 --> 00:39:10,880
we felt like they were good batteries we

739
00:39:15,270 --> 00:39:12,240
felt like if we needed to go out in a

740
00:39:16,790 --> 00:39:15,280
contingency that that we could do that

741
00:39:18,870 --> 00:39:16,800
there was no indications the batteries

742
00:39:21,030 --> 00:39:18,880
were charging they were just fine

743
00:39:22,790 --> 00:39:21,040
um but uh

744
00:39:25,030 --> 00:39:22,800
but but the fact of the matter is that

745
00:39:27,190 --> 00:39:25,040
the the test plan that they had been

746
00:39:29,109 --> 00:39:27,200
through was not consistent with what the

747
00:39:31,270 --> 00:39:29,119
original intent was which was not to put

748
00:39:32,470 --> 00:39:31,280
them through as many cycles and so so we

749
00:39:33,910 --> 00:39:32,480
made the decision we knew it was

750
00:39:35,670 --> 00:39:33,920
conservative when we made it but we

751
00:39:37,670 --> 00:39:35,680
thought it was a a good call we could

752
00:39:39,510 --> 00:39:37,680
wait on the ebas it wasn't an issue

753
00:39:41,990 --> 00:39:39,520
there and so

754
00:39:44,470 --> 00:39:42,000
so again we we made the decision to fly

755
00:39:46,550 --> 00:39:44,480
up some new batteries um and and get

756
00:39:47,750 --> 00:39:46,560
those on board and then and then get

757
00:39:49,510 --> 00:39:47,760
ourselves in a

758
00:39:52,550 --> 00:39:49,520
you know what we consider be as pristina

759
00:39:54,390 --> 00:39:52,560
shape as we could going into these evas

760
00:39:56,950 --> 00:39:54,400
thanks and for my follow-up i wondered

761
00:40:00,470 --> 00:39:56,960
if you will continue to

762
00:40:02,310 --> 00:40:00,480
use the absorbent pads and the

763
00:40:05,190 --> 00:40:02,320
the breathing tubes

764
00:40:06,309 --> 00:40:05,200
that you used after the

765
00:40:09,829 --> 00:40:06,319
july

766
00:40:12,550 --> 00:40:09,839
2013 difficulties or is that no longer

767
00:40:17,910 --> 00:40:13,589
those are

768
00:40:21,750 --> 00:40:17,920
of our our gear going forward um

769
00:40:24,230 --> 00:40:21,760
again uh coming out of out of the issue

770
00:40:26,710 --> 00:40:24,240
that we had with luca back in 2013 we

771
00:40:29,589 --> 00:40:26,720
made a a lot of different changes

772
00:40:31,510 --> 00:40:29,599
to to minimize the overall risk and and

773
00:40:34,069 --> 00:40:31,520
part of that was things that we could do

774
00:40:37,030 --> 00:40:34,079
to to reduce the likelihood

775
00:40:39,190 --> 00:40:37,040
of having the problem but also to to to

776
00:40:41,109 --> 00:40:39,200
also reduce the consequence and and

777
00:40:43,750 --> 00:40:41,119
mitigate the consequence part of it too

778
00:40:45,910 --> 00:40:43,760
and and as part of that uh the actions

779
00:40:47,670 --> 00:40:45,920
with with having the snorkel and the

780
00:40:49,270 --> 00:40:47,680
helmet pad and so forth really really

781
00:40:51,190 --> 00:40:49,280
helps us from from the standpoint of

782
00:40:52,390 --> 00:40:51,200
mitigating a consequence should we get

783
00:40:54,230 --> 00:40:52,400
there

784
00:40:56,550 --> 00:40:54,240
again so so yeah that's going to be a

785
00:40:58,390 --> 00:40:56,560
standard part of of our

786
00:41:00,309 --> 00:40:58,400
of our preparations from this point

787
00:41:01,349 --> 00:41:00,319
forward

788
00:41:05,510 --> 00:41:01,359
robert

789
00:41:08,790 --> 00:41:07,750
keith you mentioned a list of five

790
00:41:11,190 --> 00:41:08,800
different

791
00:41:13,990 --> 00:41:11,200
uh get aheads at the end i'm wondering

792
00:41:16,710 --> 00:41:14,000
in general how with with the delay that

793
00:41:19,670 --> 00:41:16,720
were paused that we had in spacewalks

794
00:41:22,950 --> 00:41:19,680
how long the list of get aheads

795
00:41:25,030 --> 00:41:22,960
or tasks that are not critical has grown

796
00:41:30,710 --> 00:41:25,040
and

797
00:41:33,190 --> 00:41:30,720
you rank what to do next in that list

798
00:41:34,710 --> 00:41:33,200
that's an interesting question

799
00:41:36,630 --> 00:41:34,720
the list is long

800
00:41:37,670 --> 00:41:36,640
um it includes

801
00:41:39,270 --> 00:41:37,680
things that

802
00:41:41,589 --> 00:41:39,280
at the very bottom of the list that are

803
00:41:44,230 --> 00:41:41,599
probably trivial but you know would

804
00:41:46,150 --> 00:41:44,240
would be nice just just to to neaten up

805
00:41:49,510 --> 00:41:46,160
all the way up to

806
00:41:51,030 --> 00:41:49,520
tasks that would help future evas

807
00:41:53,430 --> 00:41:51,040
um by

808
00:41:55,349 --> 00:41:53,440
you know getting steps out of the way or

809
00:41:56,630 --> 00:41:55,359
or clearing a path so

810
00:41:57,829 --> 00:41:56,640
um

811
00:41:59,990 --> 00:41:57,839
i i would have to get you the

812
00:42:03,510 --> 00:42:00,000
information on on how many items are on

813
00:42:05,589 --> 00:42:03,520
that list but uh we we try to work them

814
00:42:07,270 --> 00:42:05,599
in priority order but we also try to

815
00:42:08,710 --> 00:42:07,280
work them um

816
00:42:09,670 --> 00:42:08,720
based on the location of the crew

817
00:42:11,990 --> 00:42:09,680
members

818
00:42:14,309 --> 00:42:12,000
throughout the existing eva

819
00:42:17,190 --> 00:42:14,319
what ones would work best so

820
00:42:19,750 --> 00:42:17,200
um we have a prioritized list

821
00:42:22,870 --> 00:42:19,760
of of things that have to happen

822
00:42:23,990 --> 00:42:22,880
probably more based on uh on criticality

823
00:42:26,390 --> 00:42:24,000
of of

824
00:42:29,190 --> 00:42:26,400
future failures or or things that would

825
00:42:30,470 --> 00:42:29,200
help us get ahead all the way down so

826
00:42:32,550 --> 00:42:30,480
um

827
00:42:34,230 --> 00:42:32,560
you know we we i wouldn't say pick and

828
00:42:36,630 --> 00:42:34,240
choose we're given a list that gets

829
00:42:39,670 --> 00:42:36,640
approved that gets uh analyzed for the

830
00:42:45,910 --> 00:42:39,680
work sites that we're at and um we try

831
00:42:48,950 --> 00:42:47,510
hey uh we have uh

832
00:42:51,470 --> 00:42:48,960
one reporter on the phone bridge we'll

833
00:42:54,230 --> 00:42:51,480
come back here for follow-ups as well uh

834
00:42:55,910 --> 00:42:54,240
miriamkramerspace.com you there

835
00:43:00,470 --> 00:42:55,920
hi yeah thanks so much for taking my

836
00:43:03,190 --> 00:43:00,480
question um so i i am curious about how

837
00:43:06,069 --> 00:43:03,200
the spacewalk pairs were decided and

838
00:43:08,390 --> 00:43:06,079
also how the um tasks of each of the

839
00:43:10,150 --> 00:43:08,400
spacewalkers uh

840
00:43:12,309 --> 00:43:10,160
are are chosen i mean

841
00:43:15,589 --> 00:43:12,319
like for instance

842
00:43:17,510 --> 00:43:15,599
gets to ride the robotic arm so how i i

843
00:43:22,069 --> 00:43:17,520
guess i'm wondering how how all of that

844
00:43:26,390 --> 00:43:24,790
uh so i guess i'll take that one uh and

845
00:43:28,550 --> 00:43:26,400
jackie and keith can chime in at any

846
00:43:31,750 --> 00:43:28,560
point in time also uh for for an overall

847
00:43:33,349 --> 00:43:31,760
what tasks are selected um

848
00:43:35,030 --> 00:43:33,359
there's multiple things that go into

849
00:43:37,109 --> 00:43:35,040
consideration as keith even mentioned

850
00:43:40,309 --> 00:43:37,119
with the get ahead task

851
00:43:42,230 --> 00:43:40,319
primary tasks for any uh spacewalk come

852
00:43:43,990 --> 00:43:42,240
from a programmatic standpoint there are

853
00:43:44,710 --> 00:43:44,000
priorities of items that we need to get

854
00:43:46,710 --> 00:43:44,720
done

855
00:43:48,470 --> 00:43:46,720
external to the vehicle

856
00:43:52,230 --> 00:43:48,480
some of those could actually be

857
00:43:53,990 --> 00:43:52,240
completed by the spdm and robotics so we

858
00:43:55,750 --> 00:43:54,000
will try to make sure that those get

859
00:43:58,069 --> 00:43:55,760
handled uh from from a robotic

860
00:44:00,069 --> 00:43:58,079
standpoint but there are just some items

861
00:44:03,510 --> 00:44:00,079
that uh you know need a crew member's

862
00:44:05,589 --> 00:44:03,520
touch uh outside uh and so from a an

863
00:44:07,349 --> 00:44:05,599
overall programmatic side whether it's

864
00:44:10,230 --> 00:44:07,359
because a failure has happened and we

865
00:44:12,230 --> 00:44:10,240
need to respond to that failure or it's

866
00:44:15,349 --> 00:44:12,240
preparation for future activities for

867
00:44:17,270 --> 00:44:15,359
example the pmm relocation

868
00:44:19,190 --> 00:44:17,280
the the program gives us gives us a

869
00:44:20,470 --> 00:44:19,200
prioritized list of those items that

870
00:44:23,349 --> 00:44:20,480
need to be done

871
00:44:25,349 --> 00:44:23,359
we then generically plan our space walks

872
00:44:27,829 --> 00:44:25,359
for six and a half hours so we need to

873
00:44:30,790 --> 00:44:27,839
to analyze and figure out how long each

874
00:44:32,309 --> 00:44:30,800
one of those activities uh will last and

875
00:44:33,510 --> 00:44:32,319
and it's kind of like a puzzle at that

876
00:44:35,349 --> 00:44:33,520
point in time where you're you're

877
00:44:37,430 --> 00:44:35,359
putting the pieces together

878
00:44:39,190 --> 00:44:37,440
this item takes 20 minutes this item

879
00:44:40,950 --> 00:44:39,200
takes two hours and you have to come up

880
00:44:42,870 --> 00:44:40,960
with timelines that are about six and a

881
00:44:44,790 --> 00:44:42,880
half hours long

882
00:44:46,950 --> 00:44:44,800
as for which crew member

883
00:44:47,829 --> 00:44:46,960
gets to do which that's almost a puzzle

884
00:44:48,790 --> 00:44:47,839
as well

885
00:44:50,550 --> 00:44:48,800
so

886
00:44:51,829 --> 00:44:50,560
each crew member is trained

887
00:44:53,589 --> 00:44:51,839
and and they get trained on many

888
00:44:56,230 --> 00:44:53,599
activities

889
00:44:58,150 --> 00:44:56,240
specifically our our contingency

890
00:45:00,710 --> 00:44:58,160
failure response activities all the crew

891
00:45:03,430 --> 00:45:00,720
members on the u.s segment get trained

892
00:45:04,550 --> 00:45:03,440
on those so that they can respond if we

893
00:45:07,430 --> 00:45:04,560
need them

894
00:45:08,790 --> 00:45:07,440
but for planned dvas uh there's uh you

895
00:45:11,190 --> 00:45:08,800
know assessments of crew members

896
00:45:13,750 --> 00:45:11,200
capabilities uh all of our guys are and

897
00:45:15,030 --> 00:45:13,760
girls are very sharp but uh you know

898
00:45:16,710 --> 00:45:15,040
whether it's crew member size or

899
00:45:18,710 --> 00:45:16,720
anything like that we we need to take

900
00:45:21,109 --> 00:45:18,720
that in consideration when it comes down

901
00:45:23,270 --> 00:45:21,119
to performing an activity uh so that

902
00:45:26,390 --> 00:45:23,280
that kind of gets put into place uh and

903
00:45:28,069 --> 00:45:26,400
then when you look at um what tasks need

904
00:45:30,069 --> 00:45:28,079
to be done it like i said it kind of

905
00:45:32,950 --> 00:45:30,079
lays out as a puzzle as well as to which

906
00:45:33,990 --> 00:45:32,960
crew member is available at any time and

907
00:45:36,309 --> 00:45:34,000
which

908
00:45:38,230 --> 00:45:36,319
tasks best fit that person

909
00:45:39,990 --> 00:45:38,240
so yeah it looks fun because

910
00:45:42,150 --> 00:45:40,000
mr gersch gets to ride the arm around

911
00:45:43,510 --> 00:45:42,160
and it could be fun but

912
00:45:48,550 --> 00:45:43,520
he

913
00:45:54,710 --> 00:45:48,560
job and it was determined

914
00:46:00,950 --> 00:45:57,190
okay i think that was it from miriam

915
00:46:02,390 --> 00:46:00,960
back here at jsc any follow-ups

916
00:46:04,790 --> 00:46:02,400
mark

917
00:46:07,109 --> 00:46:04,800
yes i'm wondering you know if we dial

918
00:46:10,309 --> 00:46:07,119
back again uh

919
00:46:11,990 --> 00:46:10,319
to july of uh 2013

920
00:46:14,390 --> 00:46:12,000
and and the whole

921
00:46:17,109 --> 00:46:14,400
broad issue of

922
00:46:18,630 --> 00:46:17,119
conducting space walks is there any

923
00:46:20,150 --> 00:46:18,640
way to sort of

924
00:46:21,829 --> 00:46:20,160
address the

925
00:46:24,870 --> 00:46:21,839
the sort of

926
00:46:27,430 --> 00:46:24,880
overall change or improvement

927
00:46:29,829 --> 00:46:27,440
and you are a rigor in conducting space

928
00:46:32,069 --> 00:46:29,839
walks now whether they're emergency or

929
00:46:35,190 --> 00:46:32,079
maintenance

930
00:46:36,550 --> 00:46:35,200
has this whole process put you in a

931
00:46:38,710 --> 00:46:36,560
in a better

932
00:46:40,630 --> 00:46:38,720
position i assume it has but i just

933
00:46:41,750 --> 00:46:40,640
don't know how you look at it from a

934
00:46:43,750 --> 00:46:41,760
management

935
00:46:44,790 --> 00:46:43,760
standpoint

936
00:46:46,550 --> 00:46:44,800
part of the

937
00:46:55,109 --> 00:46:46,560
the

938
00:46:58,950 --> 00:46:55,119
board that was formed

939
00:47:00,950 --> 00:46:58,960
to look at all facets not just the the

940
00:47:02,950 --> 00:47:00,960
technical part of what happened but also

941
00:47:05,510 --> 00:47:02,960
look at at the management aspects

942
00:47:08,470 --> 00:47:05,520
cultural aspects what have you to try to

943
00:47:11,990 --> 00:47:08,480
try to see whether were there gaps in in

944
00:47:14,870 --> 00:47:12,000
the way the we prepared for evas on all

945
00:47:16,309 --> 00:47:14,880
fronts and so um

946
00:47:18,710 --> 00:47:16,319
coming out of that there was a series of

947
00:47:20,470 --> 00:47:18,720
recommendations that were were made

948
00:47:22,630 --> 00:47:20,480
there was an eva recovery team that was

949
00:47:24,549 --> 00:47:22,640
put in place to go in and work all of

950
00:47:25,349 --> 00:47:24,559
those recommendations

951
00:47:28,150 --> 00:47:25,359
so

952
00:47:30,309 --> 00:47:28,160
when you look back at at where we were

953
00:47:32,069 --> 00:47:30,319
then going into evas and our prep level

954
00:47:34,630 --> 00:47:32,079
of preparation now

955
00:47:37,829 --> 00:47:34,640
i would tell you that i think we're

956
00:47:39,750 --> 00:47:37,839
we're communicating better i think the

957
00:47:41,349 --> 00:47:39,760
working the suits and working with the

958
00:47:43,270 --> 00:47:41,359
program and working with our ops

959
00:47:44,630 --> 00:47:43,280
community i think there's a lot a lot

960
00:47:46,549 --> 00:47:44,640
tighter

961
00:47:48,870 --> 00:47:46,559
coordination that's happening about

962
00:47:50,309 --> 00:47:48,880
issues with suits and and how that flows

963
00:47:52,630 --> 00:47:50,319
into operations and how we make

964
00:47:54,390 --> 00:47:52,640
management decisions so

965
00:47:56,790 --> 00:47:54,400
i think there is a

966
00:48:00,150 --> 00:47:56,800
a certain level of awareness

967
00:48:02,150 --> 00:48:00,160
across the community now that that

968
00:48:04,390 --> 00:48:02,160
that is enhanced that's been put in

969
00:48:06,309 --> 00:48:04,400
place and that that through our review

970
00:48:08,230 --> 00:48:06,319
process and and just our basic

971
00:48:11,109 --> 00:48:08,240
communications is much much better than

972
00:48:15,750 --> 00:48:12,630
robert

973
00:48:17,829 --> 00:48:15,760
um sort of the flip side of get ahead

974
00:48:20,150 --> 00:48:17,839
it was mentioned that all three are

975
00:48:22,950 --> 00:48:20,160
rookie space walkers and that they're

976
00:48:24,790 --> 00:48:22,960
well trained that they've gone through

977
00:48:26,790 --> 00:48:24,800
the pool and such but

978
00:48:28,069 --> 00:48:26,800
is there any time loaded at the front to

979
00:48:30,470 --> 00:48:28,079
give to let them

980
00:48:31,670 --> 00:48:30,480
sort of gain their their space legs so

981
00:48:33,270 --> 00:48:31,680
to speak

982
00:48:37,270 --> 00:48:33,280
and to just get familiar working in the

983
00:48:39,030 --> 00:48:37,280
emu in the vacuum of outer space

984
00:48:42,470 --> 00:48:39,040
yeah for for every first time

985
00:48:44,390 --> 00:48:42,480
spacewalker we do put about 15 to 20

986
00:48:46,309 --> 00:48:44,400
minutes at the beginning just after

987
00:48:48,950 --> 00:48:46,319
egress that we call translation

988
00:48:50,549 --> 00:48:48,960
adaptation and we give them some points

989
00:48:52,309 --> 00:48:50,559
and tips of

990
00:48:54,549 --> 00:48:52,319
different movements to make just so they

991
00:48:56,470 --> 00:48:54,559
can get used to the feel of themselves

992
00:48:59,510 --> 00:48:56,480
in the suit in the vacuum of space for

993
00:49:02,150 --> 00:48:59,520
the first time and then we also pad our

994
00:49:03,750 --> 00:49:02,160
evas for all crew members because it is

995
00:49:06,630 --> 00:49:03,760
different than what we do in the the

996
00:49:08,150 --> 00:49:06,640
water so that we have plenty of time so

997
00:49:10,630 --> 00:49:08,160
we're not rushing the crew members when

998
00:49:12,870 --> 00:49:10,640
they're out the door

999
00:49:17,030 --> 00:49:12,880
i'd also like to add that

1000
00:49:21,510 --> 00:49:17,040
during usc va 28 we are shooting for

1001
00:49:23,670 --> 00:49:21,520
a specific eclipse to start the ssu task

1002
00:49:26,870 --> 00:49:23,680
and as part of that we take into account

1003
00:49:28,069 --> 00:49:26,880
that we have one rookie and

1004
00:49:29,990 --> 00:49:28,079
the other crew member will have

1005
00:49:33,589 --> 00:49:30,000
completed reed will have completed an

1006
00:49:34,549 --> 00:49:33,599
eva the week before so we'll use that to

1007
00:49:35,910 --> 00:49:34,559
judge

1008
00:49:37,030 --> 00:49:35,920
what it takes to get them out to the

1009
00:49:37,750 --> 00:49:37,040
work site but

1010
00:49:39,589 --> 00:49:37,760
we

1011
00:49:41,910 --> 00:49:39,599
leave enough margin so that they should

1012
00:49:45,589 --> 00:49:41,920
be there and set up at the work site

1013
00:49:49,829 --> 00:49:48,069
any other follow-ups here

1014
00:49:51,510 --> 00:49:49,839
okay i think that's it for questions

1015
00:49:53,990 --> 00:49:51,520
we'll close uh the briefing with a

1016
00:49:56,150 --> 00:49:54,000
programming note our spacewalk coverage

1017
00:49:59,190 --> 00:49:56,160
on nasa television next tuesday october

1018
00:50:02,150 --> 00:49:59,200

eastern time the beginning of a busy

1021
00:50:07,990 --> 00:50:05,599
several months aboard the international

1022
00:50:11,190 --> 00:50:08,000
space station you can follow all of the

1023
00:50:15,190 --> 00:50:11,200
iss activities every day on our website

1024
00:50:19,030 --> 00:50:17,270
station with that we'll sign off for
