1
00:00:05,349 --> 00:00:03,669
good morning and once again welcome back

2
00:00:07,110 --> 00:00:05,359
to nasa's johnson space center in

3
00:00:10,070 --> 00:00:07,120
houston as we continue to take a look at

4
00:00:11,509 --> 00:00:10,080
the sts-131 mission and discovery's

5
00:00:13,110 --> 00:00:11,519
upcoming flight to the international

6
00:00:14,789 --> 00:00:13,120
space station here now to give us more

7
00:00:16,710 --> 00:00:14,799
details about all the spacewalks that

8
00:00:18,950 --> 00:00:16,720
are planned for this flight is the lead

9
00:00:20,390 --> 00:00:18,960
spacewalk officer for this mission david

10
00:00:22,070 --> 00:00:20,400
cohen go ahead dave

11
00:00:25,029 --> 00:00:22,080
good morning my name is david cohen i'm

12
00:00:27,109 --> 00:00:25,039
the eva lead for sts-131 we'll be doing

13
00:00:28,870 --> 00:00:27,119
a three space walks on the mission

14
00:00:31,349 --> 00:00:28,880
our primary objective being to changing

15
00:00:33,790 --> 00:00:31,359
out the starboard ammonia tank assembly

16
00:00:35,990 --> 00:00:33,800
we changed out the port money tank on

17
00:00:37,670 --> 00:00:36,000
sts-128 so we'll be doing the other one

18
00:00:38,950 --> 00:00:37,680
on this one that's going to take us

19
00:00:40,709 --> 00:00:38,960
about we'll take we'll take us three

20
00:00:42,869 --> 00:00:40,719
evas

21
00:00:44,310 --> 00:00:42,879
the amount intake itself is roughly

22
00:00:45,830 --> 00:00:44,320
actually the size and weight of a first

23
00:00:47,590 --> 00:00:45,840
generation smart car so it's a fairly

24
00:00:49,990 --> 00:00:47,600
big box we'll be changing out so we'll

25
00:00:53,029 --> 00:00:50,000
be using the robotic arm to do that

26
00:00:54,630 --> 00:00:53,039
we'll be using the arm all three evas

27
00:00:56,869 --> 00:00:54,640
just uh real quickly before we get into

28
00:00:59,430 --> 00:00:56,879
the evas our crew is going to be

29
00:01:01,910 --> 00:00:59,440
rick mastracchio will be our ev1 wearing

30
00:01:04,070 --> 00:01:01,920
the red stripe this is actually his

31
00:01:06,390 --> 00:01:04,080
third space flight he's done three va's

32
00:01:07,990 --> 00:01:06,400
before on sts-118

33
00:01:10,550 --> 00:01:08,000
ev2 wearing the white stripes will be

34
00:01:12,310 --> 00:01:10,560
clay anderson he's also done three evas

35
00:01:13,910 --> 00:01:12,320
he was an expedition 15 crew member so

36
00:01:15,429 --> 00:01:13,920
this will be his second flight and he

37
00:01:18,070 --> 00:01:15,439
actually did two of those evas with the

38
00:01:19,190 --> 00:01:18,080
sts-118 crew so rick and clay are very

39
00:01:22,469 --> 00:01:19,200
experienced crew members and actually

40
00:01:24,469 --> 00:01:22,479
experienced in doing evas together

41
00:01:26,710 --> 00:01:24,479
dottie metcalf lindenberger will be our

42
00:01:28,630 --> 00:01:26,720
uh intravecular activity crew member so

43
00:01:31,109 --> 00:01:28,640
our task iv and she will be

44
00:01:31,990 --> 00:01:31,119
choreographing the day and taking the ev

45
00:01:33,590 --> 00:01:32,000
crew

46
00:01:35,190 --> 00:01:33,600
through the procedures

47
00:01:36,950 --> 00:01:35,200
and jim dutton who's the pilot on the

48
00:01:38,390 --> 00:01:36,960
flight will be our suit iv so he'll be

49
00:01:39,270 --> 00:01:38,400
responsible for suiting out brick and

50
00:01:41,270 --> 00:01:39,280
clay

51
00:01:42,870 --> 00:01:41,280
into their spaces before the space walks

52
00:01:44,069 --> 00:01:42,880
and getting them out after the space

53
00:01:45,830 --> 00:01:44,079
walks

54
00:01:50,310 --> 00:01:45,840
so we can take a look at the eva one

55
00:01:53,590 --> 00:01:52,310
the crew will start off as we do all evs

56
00:02:00,630 --> 00:01:53,600
from space station from the joint

57
00:02:04,870 --> 00:02:01,990
the first thing he's going to do is head

58
00:02:06,389 --> 00:02:04,880
up to the old starboard ammonia tank and

59
00:02:08,309 --> 00:02:06,399
he's going to grab a fixed grapple bar

60
00:02:09,510 --> 00:02:08,319
which you see flashing in blue he's

61
00:02:11,270 --> 00:02:09,520
going to unbolt that from the old

62
00:02:12,869 --> 00:02:11,280
ammonia tank

63
00:02:14,550 --> 00:02:12,879
and he'll actually take this over to the

64
00:02:15,750 --> 00:02:14,560
payload bay

65
00:02:18,150 --> 00:02:15,760
and we'll be using this fixed scrap of

66
00:02:20,630 --> 00:02:18,160
bar this is what allows the the station

67
00:02:22,150 --> 00:02:20,640
robotic arm to grapple the ammonia tank

68
00:02:24,229 --> 00:02:22,160
like i said before we'll be using the

69
00:02:25,990 --> 00:02:24,239
robotic arm to move the ammoni tank for

70
00:02:27,910 --> 00:02:26,000
all three evas since it's so big and

71
00:02:29,589 --> 00:02:27,920
heavy

72
00:02:32,949 --> 00:02:29,599
so rick will grab that fixed grapple bar

73
00:02:34,630 --> 00:02:32,959
and he'll translate down space station

74
00:02:36,550 --> 00:02:34,640
he will do a tether swap to a second

75
00:02:38,309 --> 00:02:36,560
safety tether on the japanese experiment

76
00:02:39,589 --> 00:02:38,319
module then he'll head down to the

77
00:02:40,630 --> 00:02:39,599
payload bay

78
00:02:42,070 --> 00:02:40,640
once he gets there he's going to go

79
00:02:44,070 --> 00:02:42,080
after the payload bait he's going to

80
00:02:46,790 --> 00:02:44,080
temporarily stow that fgb that fixed

81
00:02:48,869 --> 00:02:46,800
gravel bar on the lmc and the lmc is a

82
00:02:50,470 --> 00:02:48,879
platform that we're used to launch the

83
00:02:55,270 --> 00:02:50,480
new ammonia tank which is the big white

84
00:02:58,790 --> 00:02:56,949
while he's doing that clay is going to

85
00:03:00,630 --> 00:02:58,800
follow him out of the airlock and clay

86
00:03:02,149 --> 00:03:00,640
will also head up to the old starboard

87
00:03:03,030 --> 00:03:02,159
ammonia tank

88
00:03:05,030 --> 00:03:03,040
and

89
00:03:06,949 --> 00:03:05,040
he is going to

90
00:03:08,470 --> 00:03:06,959
disconnect the nitrogen lines and the

91
00:03:10,229 --> 00:03:08,480
ammonia lines that go to that ammonia

92
00:03:12,070 --> 00:03:10,239
tank

93
00:03:15,910 --> 00:03:12,080
this is just in preparation for eva2

94
00:03:17,270 --> 00:03:15,920
when we actually swap out this tank

95
00:03:18,869 --> 00:03:17,280
so once he's done disconnecting those

96
00:03:20,550 --> 00:03:18,879
four lines he'll put the the thermal

97
00:03:22,790 --> 00:03:20,560
cover back over him he'll go to the

98
00:03:25,110 --> 00:03:22,800
forward side of the truss

99
00:03:27,430 --> 00:03:25,120
to a cedar cart see the card is a mobile

100
00:03:28,789 --> 00:03:27,440
eva work platform that we use and he's

101
00:03:30,789 --> 00:03:28,799
going to grab an articulated portable

102
00:03:32,550 --> 00:03:30,799
foot restraint or just a foot restraint

103
00:03:34,550 --> 00:03:32,560
from that seed to cart put it on his

104
00:03:39,270 --> 00:03:34,560
body restraint tether and he'll take

105
00:03:43,190 --> 00:03:41,509
so on his way there just as rick did

106
00:03:44,630 --> 00:03:43,200
clay will do a tether swap to a second

107
00:03:46,470 --> 00:03:44,640
tether to allow him to reach the payload

108
00:03:48,309 --> 00:03:46,480
bay except he'll do it on top of the

109
00:03:49,830 --> 00:03:48,319
node 2 module

110
00:03:55,589 --> 00:03:49,840
then he'll head down and meet rick in

111
00:03:58,630 --> 00:03:57,509
and once he's at the lmc

112
00:04:00,710 --> 00:03:58,640
clay is going to install his foot

113
00:04:03,030 --> 00:04:00,720
restraint into a worksite interface or a

114
00:04:07,190 --> 00:04:04,710
and while clay is doing that rick is

115
00:04:09,190 --> 00:04:07,200
going to bolt that fixed grapple bar to

116
00:04:10,710 --> 00:04:09,200
the side of the ammonia tank you can see

117
00:04:11,670 --> 00:04:10,720
the fixed ground bar is flashing in blue

118
00:04:13,990 --> 00:04:11,680
here

119
00:04:15,589 --> 00:04:14,000
so bolt that on and this is again what

120
00:04:18,310 --> 00:04:15,599
the arm will use to grapple the ammoni

121
00:04:20,069 --> 00:04:18,320
tank so we can move it

122
00:04:22,390 --> 00:04:20,079
simultaneously clay will be installing

123
00:04:23,990 --> 00:04:22,400
that full restraint into the lmc

124
00:04:26,629 --> 00:04:24,000
once he gets it installed he will pop

125
00:04:28,150 --> 00:04:26,639
into it and

126
00:04:30,070 --> 00:04:28,160
rick and clay will then unbolt the four

127
00:04:31,270 --> 00:04:30,080
bolts that hold the ammonia tank to the

128
00:04:32,790 --> 00:04:31,280
lmc

129
00:04:34,950 --> 00:04:32,800
and they'll pick it up out of the soft

130
00:04:49,670 --> 00:04:34,960
docks and hand it to the arm or the arm

131
00:04:53,350 --> 00:04:51,110
once the arm has it clay's going to

132
00:04:54,550 --> 00:04:53,360
remove his foot restraint off the lmc

133
00:04:57,030 --> 00:04:54,560
he's going to take it out of the payload

134
00:05:00,629 --> 00:04:57,040
bay and put it on node 2 and just leave

135
00:05:02,150 --> 00:05:00,639
it there until he needs to get on eva3

136
00:05:03,749 --> 00:05:02,160
and while he's doing that rick is going

137
00:05:05,110 --> 00:05:03,759
to be translating out to the japanese

138
00:05:06,710 --> 00:05:05,120
experiment module to the exposed

139
00:05:08,790 --> 00:05:06,720
facility on it where he's going to

140
00:05:10,629 --> 00:05:08,800
retrieve the impact seed experiment an

141
00:05:12,550 --> 00:05:10,639
impact seed is a materials experiment

142
00:05:13,990 --> 00:05:12,560
that the japanese have out there so

143
00:05:15,510 --> 00:05:14,000
he'll go out and see it flashing in blue

144
00:05:17,749 --> 00:05:15,520
there and he'll install a cover on it to

145
00:05:19,510 --> 00:05:17,759
protect the experiment then he'll take

146
00:05:21,270 --> 00:05:19,520
it off and put it on his body restraint

147
00:05:22,550 --> 00:05:21,280
tether here's some mbl footage of him

148
00:05:24,070 --> 00:05:22,560
unbolting it

149
00:05:25,350 --> 00:05:24,080
and the experiment itself is what's in

150
00:05:27,189 --> 00:05:25,360
his left hand

151
00:05:29,189 --> 00:05:27,199
so he's using his pistol grip too to

152
00:05:30,870 --> 00:05:29,199
tool to undo the bolts on it

153
00:05:32,550 --> 00:05:30,880
and then he'll pop the experiment off

154
00:05:36,870 --> 00:05:32,560
put it on his brt

155
00:05:43,670 --> 00:05:38,390
and again the impact is what just came

156
00:05:47,430 --> 00:05:45,350
so translate back down the japanese

157
00:05:48,469 --> 00:05:47,440
module back down space station to the

158
00:05:50,310 --> 00:05:48,479
airlock and he's just going to

159
00:05:52,230 --> 00:05:50,320
temporarily stow the impact seat on the

160
00:06:00,469 --> 00:05:52,240
outside of the airlock until he puts it

161
00:06:04,150 --> 00:06:01,990
and while this is happening the arm is

162
00:06:05,510 --> 00:06:04,160
moving the new ammonia tank that we just

163
00:06:07,590 --> 00:06:05,520
took from the ev crew and the payload

164
00:06:09,350 --> 00:06:07,600
bay over to the external storage

165
00:06:11,270 --> 00:06:09,360
platform 2 or esp-2 which is just

166
00:06:12,790 --> 00:06:11,280
outside the airlock and rick and clay

167
00:06:14,550 --> 00:06:12,800
are going to meet the arm there they're

168
00:06:16,309 --> 00:06:14,560
going to take an adjustable grapple bar

169
00:06:18,629 --> 00:06:16,319
off of the spare flex hose rotary

170
00:06:21,189 --> 00:06:18,639
coupler or fhrc and they're going to

171
00:06:23,270 --> 00:06:21,199
mount this grapple bar to the ata here's

172
00:06:24,790 --> 00:06:23,280
some mbl footage of them installing that

173
00:06:27,029 --> 00:06:24,800
onto the ata

174
00:06:29,189 --> 00:06:27,039
and basically the this is going to be

175
00:06:32,070 --> 00:06:29,199
used for the poe which is the payload

176
00:06:35,270 --> 00:06:32,080
oru accommodation device on the mobile

177
00:06:37,430 --> 00:06:35,280
platform or the the mobile transporter

178
00:06:39,749 --> 00:06:37,440
it has an end effector just like the arm

179
00:06:42,469 --> 00:06:39,759
so the robotic arm will fly the ata over

180
00:06:44,870 --> 00:06:42,479
to the poa and actually the pole then

181
00:06:46,710 --> 00:06:44,880
grapple this adjustable grapple bar

182
00:06:48,550 --> 00:06:46,720
and then the arm will release the ata

183
00:06:51,830 --> 00:06:48,560
and we'll leave it there between eva 1

184
00:06:55,189 --> 00:06:53,510
while that's happening clay is going to

185
00:06:57,189 --> 00:06:55,199
come inside to the forward part of the

186
00:06:59,909 --> 00:06:57,199
truss here and he's going to unbolt two

187
00:07:01,350 --> 00:06:59,919
bolts on a rate gyro assembly so the rga

188
00:07:02,870 --> 00:07:01,360
is another box the crew will be changing

189
00:07:03,990 --> 00:07:02,880
out

190
00:07:05,350 --> 00:07:04,000
its bolt that has two bolts on the

191
00:07:06,710 --> 00:07:05,360
inside of truss and then two bolts on

192
00:07:07,909 --> 00:07:06,720
the outside of that truss so while clay

193
00:07:10,390 --> 00:07:07,919
is on the inside and the forward side of

194
00:07:14,230 --> 00:07:10,400
the truss rick will go get the spare rga

195
00:07:17,670 --> 00:07:15,430
and he's gonna he's gonna attempt stow

196
00:07:18,629 --> 00:07:17,680
the bag that has that rga in it the new

197
00:07:19,909 --> 00:07:18,639
one

198
00:07:22,309 --> 00:07:19,919
then he'll configure the work site so we

199
00:07:23,670 --> 00:07:22,319
can pull out the old one

200
00:07:25,029 --> 00:07:23,680
he'll move that flashing piece of

201
00:07:25,830 --> 00:07:25,039
equipment if he needs to get it out of

202
00:07:27,830 --> 00:07:25,840
the way

203
00:07:31,029 --> 00:07:27,840
it'll open up a thermal blanket he'll

204
00:07:33,909 --> 00:07:31,039
unbolt the failed or the old rga and

205
00:07:37,110 --> 00:07:35,270
and here's some nbl footage of him

206
00:07:40,390 --> 00:07:37,120
pulling that out

207
00:07:42,230 --> 00:07:40,400
it's a little bit smaller than an ata

208
00:07:44,070 --> 00:07:42,240
so he'll tempt that just above him and

209
00:07:46,710 --> 00:07:44,080
he'll grab the new one from the bag he

210
00:07:47,909 --> 00:07:46,720
brought out with him install the new one

211
00:07:49,510 --> 00:07:47,919
put the old one in the bag and then

212
00:07:51,670 --> 00:07:49,520
clean up the work site put the thermal

213
00:07:52,869 --> 00:07:51,680
blanket back over the rga and put an

214
00:08:05,589 --> 00:07:52,879
equipment back that he had to move to

215
00:08:09,110 --> 00:08:07,830
when he's installing the new rga he's

216
00:08:10,869 --> 00:08:09,120
going to take the old ones in the bag

217
00:08:12,629 --> 00:08:10,879
now and take the forts of the trust and

218
00:08:13,909 --> 00:08:12,639
just temporarily stow it there and it'll

219
00:08:16,390 --> 00:08:13,919
leave it and pick it up on his way

220
00:08:17,589 --> 00:08:16,400
inside the airlock later on

221
00:08:19,670 --> 00:08:17,599
once he temps does it he's going to go

222
00:08:21,270 --> 00:08:19,680
inside the truss and install the two

223
00:08:22,869 --> 00:08:21,280
bolts that clay had removed on the old

224
00:08:24,309 --> 00:08:22,879
one

225
00:08:26,309 --> 00:08:24,319
so while rick is doing this clay's going

226
00:08:27,830 --> 00:08:26,319
to be heading out to the far port side

227
00:08:30,390 --> 00:08:27,840
of the truss so heading all the way out

228
00:08:31,589 --> 00:08:30,400
to p6

229
00:08:33,909 --> 00:08:31,599
and he'll be doing some work for the

230
00:08:37,589 --> 00:08:33,919
next flight for sts-132 they're changing

231
00:08:39,110 --> 00:08:37,599
out batteries on the p6 truss segment

232
00:08:41,110 --> 00:08:39,120
there's already two foot restraints and

233
00:08:43,190 --> 00:08:41,120
two gap spanners that the crew uses to

234
00:08:44,630 --> 00:08:43,200
do the the r r the batteries they were

235
00:08:46,630 --> 00:08:44,640
out there for the last crew that did the

236
00:08:48,550 --> 00:08:46,640
one side of the battery so sts-132 will

237
00:08:49,829 --> 00:08:48,560
do the other side so clay's going to

238
00:08:51,110 --> 00:08:49,839
grab one of those foot restraints and

239
00:08:52,150 --> 00:08:51,120
one the gap spanners from one side of

240
00:08:53,190 --> 00:08:52,160
the truss

241
00:08:56,150 --> 00:08:53,200
you're just going to move around to the

242
00:08:59,829 --> 00:08:58,230
so battery removing replace takes is

243
00:09:01,590 --> 00:08:59,839
quite time consuming so anything we can

244
00:09:04,949 --> 00:09:01,600
do to help the next crew get started on

245
00:09:06,949 --> 00:09:04,959
that is a something they appreciated

246
00:09:09,190 --> 00:09:06,959
so install the gas spinner and install

247
00:09:11,030 --> 00:09:09,200
the foot restraint

248
00:09:13,110 --> 00:09:11,040
as soon as rick is done with his last

249
00:09:15,430 --> 00:09:13,120
two bolts on the ray gyro assembly he

250
00:09:17,030 --> 00:09:15,440
will head out to p6 also

251
00:09:18,949 --> 00:09:17,040
and he will grab a second full restraint

252
00:09:20,550 --> 00:09:18,959
and a second gap spanner and he will

253
00:09:23,590 --> 00:09:20,560
also move those to the other side of the

254
00:09:25,110 --> 00:09:23,600
p6 truss segment

255
00:09:26,310 --> 00:09:25,120
while rick is doing that clay is going

256
00:09:28,230 --> 00:09:26,320
to actually start

257
00:09:30,150 --> 00:09:28,240
breaking torque on

258
00:09:31,990 --> 00:09:30,160
both bolts on all six batteries so he's

259
00:09:33,430 --> 00:09:32,000
going to release the bolt by one turn

260
00:09:35,269 --> 00:09:33,440
and then just lightly tighten it up

261
00:09:36,790 --> 00:09:35,279
again these bolts are launched with

262
00:09:38,550 --> 00:09:36,800
fairly high torque

263
00:09:40,310 --> 00:09:38,560
and to help the next crew with their

264
00:09:41,509 --> 00:09:40,320
change out to go as fast as possible

265
00:09:42,949 --> 00:09:41,519
they're just going to loosen up those

266
00:09:50,150 --> 00:09:42,959
bolts a little bit so things go quicker

267
00:09:53,670 --> 00:09:51,430
and here's an animation of rick

268
00:09:55,190 --> 00:09:53,680
installing his gap spanner so i've two

269
00:09:56,470 --> 00:09:55,200
gasping is running across the series of

270
00:10:03,990 --> 00:09:56,480
batteries and then two foot restraints

271
00:10:07,030 --> 00:10:05,910
on their way after this task if they

272
00:10:08,870 --> 00:10:07,040
have time

273
00:10:10,550 --> 00:10:08,880
the crew will mate a connector between

274
00:10:12,630 --> 00:10:10,560
p4 and p5

275
00:10:13,990 --> 00:10:12,640
this allows money to flow out to the p5

276
00:10:15,190 --> 00:10:14,000
p6 segment

277
00:10:16,470 --> 00:10:15,200
but only if we have time would be get

278
00:10:17,910 --> 00:10:16,480
ahead for them

279
00:10:22,069 --> 00:10:17,920
after that they will clean up everything

280
00:10:26,630 --> 00:10:25,269
which will conclude eva 1.

281
00:10:28,389 --> 00:10:26,640
the crew will have a day in between eva

282
00:10:29,750 --> 00:10:28,399
1 and 2 and the arm i'm sure you heard

283
00:10:31,990 --> 00:10:29,760
before in the other

284
00:10:33,670 --> 00:10:32,000
briefing we'll walk off between the evas

285
00:10:35,430 --> 00:10:33,680
this will allow the arm to have access

286
00:10:37,990 --> 00:10:35,440
to the actual old

287
00:10:40,230 --> 00:10:38,000
ata worksite

288
00:10:42,470 --> 00:10:40,240
and so that the main thing for eva2 will

289
00:10:44,150 --> 00:10:42,480
be the actual swapping of the old

290
00:10:45,590 --> 00:10:44,160
ammonia tank with the new ammonia tank

291
00:10:49,509 --> 00:10:45,600
so if we take a look at the video for

292
00:10:57,350 --> 00:10:51,509
so on eva 2 uh

293
00:11:01,030 --> 00:10:58,630
and the first thing that i'll do is

294
00:11:02,550 --> 00:11:01,040
wrinkle head up to the old ammonia tank

295
00:11:04,069 --> 00:11:02,560
he's going to grab a foot restraint from

296
00:11:05,350 --> 00:11:04,079
the airlock it's flashing blue there

297
00:11:07,829 --> 00:11:05,360
he's going to put it just below the old

298
00:11:09,430 --> 00:11:07,839
ammonia tank he's going to ingress it

299
00:11:11,910 --> 00:11:09,440
clay will go up and meet him at the

300
00:11:14,069 --> 00:11:11,920
ammoni tank and they'll undo the four

301
00:11:16,069 --> 00:11:14,079
bolts that hold it into the truss and

302
00:11:18,310 --> 00:11:16,079
lift it up here's some mbl footage of

303
00:11:19,910 --> 00:11:18,320
rick lifting it off the truss

304
00:11:22,150 --> 00:11:19,920
it's a pretty big box so they move it

305
00:11:23,590 --> 00:11:22,160
pretty slowly

306
00:11:25,190 --> 00:11:23,600
they'll hand it off to the arm and the

307
00:11:30,069 --> 00:11:25,200
arm will grapple a fixed grapple bar

308
00:11:33,030 --> 00:11:31,350
and the arm's going to maneuver the

309
00:11:34,790 --> 00:11:33,040
money tank away from the trust and to

310
00:11:36,710 --> 00:11:34,800
the forward side of the truss

311
00:11:38,870 --> 00:11:36,720
so rick and clay will follow the arm

312
00:11:40,790 --> 00:11:38,880
from the back side to the forward side

313
00:11:43,269 --> 00:11:40,800
and on his way rick's going to uncouple

314
00:11:44,550 --> 00:11:43,279
a cedar cart from the mobile transporter

315
00:11:46,069 --> 00:11:44,560
and he's going to move that cd card

316
00:11:47,509 --> 00:11:46,079
outboard or away from the mobile

317
00:11:49,030 --> 00:11:47,519
transporter

318
00:11:51,430 --> 00:11:49,040
he's going to configure it so they can

319
00:11:52,389 --> 00:11:51,440
use it to stow the old ammonia tank

320
00:11:53,990 --> 00:11:52,399
basically he's going to fold the brake

321
00:11:55,829 --> 00:11:54,000
handles down and fold the foot

322
00:11:59,030 --> 00:11:55,839
restraints clear make it as clear as

323
00:12:00,150 --> 00:11:59,040
possible as flat as possible

324
00:12:01,750 --> 00:12:00,160
while he's doing that the arm's gonna

325
00:12:03,750 --> 00:12:01,760
start maneuvering the old ammonia tank

326
00:12:04,870 --> 00:12:03,760
closest to the cart and rick and clay

327
00:12:06,550 --> 00:12:04,880
will get in position on either side of

328
00:12:08,389 --> 00:12:06,560
the seat of guard there

329
00:12:10,069 --> 00:12:08,399
and when the money tank gets close

330
00:12:12,790 --> 00:12:10,079
enough they will attach six adjustable

331
00:12:15,110 --> 00:12:12,800
equipment tethers to the old ata

332
00:12:16,710 --> 00:12:15,120
and tie it down to the cedar cart i'm

333
00:12:18,629 --> 00:12:16,720
just going to leave it tied down here

334
00:12:21,030 --> 00:12:18,639
for two or three hours while we install

335
00:12:22,710 --> 00:12:21,040
the new ata

336
00:12:24,710 --> 00:12:22,720
and you can see the equipment tethers

337
00:12:26,389 --> 00:12:24,720
flashing in blue there

338
00:12:28,710 --> 00:12:26,399
so during while this is happening the uh

339
00:12:30,870 --> 00:12:28,720
arm's gonna go get the new ammoni tank

340
00:12:32,710 --> 00:12:30,880
that it temp stowed in the poa on eva

341
00:12:33,990 --> 00:12:32,720
one it takes him a little bit of time to

342
00:12:36,550 --> 00:12:34,000
do that so rick and clay are gonna

343
00:12:39,110 --> 00:12:36,560
translate to the bottom side of the port

344
00:12:41,030 --> 00:12:39,120
p1 segment and they're going to install

345
00:12:43,350 --> 00:12:41,040
radiator grapple fixture stowage beams

346
00:12:44,310 --> 00:12:43,360
two of them on the actual port radiator

347
00:12:47,670 --> 00:12:44,320
beam

348
00:12:49,269 --> 00:12:47,680
in blue there are used to temp stow a

349
00:12:50,790 --> 00:12:49,279
grapple fixture that we'd use if we ever

350
00:12:52,550 --> 00:12:50,800
had to change out a radiator in the

351
00:12:53,910 --> 00:12:52,560
future

352
00:12:55,350 --> 00:12:53,920
so that'll take them about half an hour

353
00:12:57,350 --> 00:12:55,360
give the arm enough time to grab that

354
00:12:58,870 --> 00:12:57,360
new ammonia tank out of the poa and

355
00:13:00,550 --> 00:12:58,880
maneuver it down to the truss just a

356
00:13:02,310 --> 00:13:00,560
little bit inboard of the old ammonia

357
00:13:03,590 --> 00:13:02,320
tank

358
00:13:05,350 --> 00:13:03,600
we're glad they're going to get that

359
00:13:07,990 --> 00:13:05,360
adjustable grapple bar they put on on

360
00:13:10,069 --> 00:13:08,000
eva1 take it off and just temp stowed in

361
00:13:11,110 --> 00:13:10,079
the truss

362
00:13:12,710 --> 00:13:11,120
while they're doing that the arm is

363
00:13:15,110 --> 00:13:12,720
going to maneuver that new money tank to

364
00:13:17,030 --> 00:13:15,120
the backside of s1

365
00:13:18,710 --> 00:13:17,040
to the work site where they can install

366
00:13:20,150 --> 00:13:18,720
it

367
00:13:21,670 --> 00:13:20,160
and rick and clay will follow the arm

368
00:13:23,030 --> 00:13:21,680
along

369
00:13:24,310 --> 00:13:23,040
so they'll get set up in the same

370
00:13:27,350 --> 00:13:24,320
position where they release the old

371
00:13:30,389 --> 00:13:28,790
and the arm will drive the ammonia tank

372
00:13:31,590 --> 00:13:30,399
in close to them they'll take control

373
00:13:33,430 --> 00:13:31,600
over it the armor will release the

374
00:13:45,430 --> 00:13:33,440
amount of tank and rick and clay will

375
00:13:48,790 --> 00:13:46,870
here's some mbl footage of rick and his

376
00:13:50,470 --> 00:13:48,800
foot restraint bringing that ammonia

377
00:13:52,069 --> 00:13:50,480
tank in

378
00:13:53,590 --> 00:13:52,079
once again in soft dock they'll install

379
00:13:55,110 --> 00:13:53,600
install the four bolts that hold in

380
00:13:57,030 --> 00:13:55,120
place install the two electrical

381
00:14:05,269 --> 00:13:57,040
connectors to it the two nitrogen lines

382
00:14:09,030 --> 00:14:07,670
once they're done with that uh they will

383
00:14:11,189 --> 00:14:09,040
translate back to the fourth side of the

384
00:14:13,030 --> 00:14:11,199
truss where they left the old ata

385
00:14:14,550 --> 00:14:13,040
and the arm is going to meet them there

386
00:14:16,710 --> 00:14:14,560
so they'll untie the old ata from the

387
00:14:20,790 --> 00:14:16,720
cedar cart and pick it up and hand it

388
00:14:24,629 --> 00:14:22,230
the arms isn't going to maneuver the old

389
00:14:26,069 --> 00:14:24,639
at a little bit inboard

390
00:14:27,670 --> 00:14:26,079
closer to where rick and clay left that

391
00:14:29,829 --> 00:14:27,680
adjustable grapple bar

392
00:14:31,430 --> 00:14:29,839
so they're going to go untemp stow that

393
00:14:33,910 --> 00:14:31,440
and they will install the adjustable

394
00:14:35,509 --> 00:14:33,920
gravel bar onto the old ata

395
00:14:37,910 --> 00:14:35,519
much like they did with the new at on

396
00:14:39,590 --> 00:14:37,920
eva1

397
00:14:41,990 --> 00:14:39,600
and this will allow the arm to plug the

398
00:14:53,189 --> 00:14:42,000
old ata into the poa and leave it there

399
00:14:56,069 --> 00:14:54,949
while the armor is plugging the old atm

400
00:14:58,470 --> 00:14:56,079
to the poa rick and clay are going to

401
00:15:00,230 --> 00:14:58,480
translate back to esp2

402
00:15:02,069 --> 00:15:00,240
just outside the airlock they're going

403
00:15:04,150 --> 00:15:02,079
to grab two debris shields you see

404
00:15:07,829 --> 00:15:04,160
flashing in blue these debris shields

405
00:15:09,189 --> 00:15:07,839
the sts-129 crew tied down to the esp-2

406
00:15:11,110 --> 00:15:09,199
so rick and clay are going to untie

407
00:15:13,910 --> 00:15:11,120
those put them in the airlock and follow

408
00:15:22,310 --> 00:15:13,920
those inside to ingress and finish up

409
00:15:25,829 --> 00:15:23,990
between evas the arm's gonna walk off

410
00:15:27,829 --> 00:15:25,839
once again go back to node 2 where it

411
00:15:29,749 --> 00:15:27,839
can reach the payload bay and the

412
00:15:31,189 --> 00:15:29,759
primary goal of eva 3 will be to get

413
00:15:32,870 --> 00:15:31,199
that old ata

414
00:15:35,590 --> 00:15:32,880
out of the poa and backed and bolted to

415
00:15:37,350 --> 00:15:35,600
the lmc where the new one was launched

416
00:15:44,870 --> 00:15:37,360
and do a couple other tasks so if we

417
00:15:48,550 --> 00:15:46,629
rick and clay will again come out of the

418
00:15:49,910 --> 00:15:48,560
joint airlock on eva3

419
00:15:51,030 --> 00:15:49,920
and the arm

420
00:15:52,389 --> 00:15:51,040
before they're coming out while they're

421
00:15:54,550 --> 00:15:52,399
coming out it's going to grab that old

422
00:15:56,949 --> 00:15:54,560
ata out of the poa

423
00:15:58,629 --> 00:15:56,959
and it's going to meet them at esp2 and

424
00:15:59,350 --> 00:15:58,639
wrecking clay goes straight to esp2

425
00:16:01,670 --> 00:15:59,360
where they're going to take that

426
00:16:03,509 --> 00:16:01,680
adjustable grapple bar off the ata and

427
00:16:05,670 --> 00:16:03,519
put it back on the spare fhrc where they

428
00:16:07,189 --> 00:16:05,680
got it on eva1

429
00:16:08,389 --> 00:16:07,199
so while they're installing that on the

430
00:16:10,389 --> 00:16:08,399
fhrc

431
00:16:17,829 --> 00:16:10,399
the arm is going to take that old ata

432
00:16:22,069 --> 00:16:19,350
so clay's going to grab his foot

433
00:16:23,829 --> 00:16:22,079
restraint that he left the end of eva1

434
00:16:25,030 --> 00:16:23,839
ticket with them

435
00:16:26,870 --> 00:16:25,040
and rick and clay will configure

436
00:16:29,189 --> 00:16:26,880
themselves around the lmc

437
00:16:30,710 --> 00:16:29,199
to put the old ata onto the lmc for

438
00:16:32,069 --> 00:16:30,720
return

439
00:16:37,990 --> 00:16:32,079
in the same positions they were in when

440
00:16:41,509 --> 00:16:39,110
so you can see

441
00:16:43,509 --> 00:16:41,519
clay installing the apfr here

442
00:16:44,790 --> 00:16:43,519
he'll get in the full restraint

443
00:16:46,949 --> 00:16:44,800
the arm will bring the

444
00:16:48,790 --> 00:16:46,959
ata in close the crew will take hold of

445
00:16:50,710 --> 00:16:48,800
it bring it down the soft dock and

446
00:16:55,110 --> 00:16:50,720
install the install the full four bolts

447
00:16:59,110 --> 00:16:56,949
and one and here's some nbl footage of

448
00:17:04,150 --> 00:16:59,120
rick bringing that ata down

449
00:17:07,829 --> 00:17:05,590
and once they've done that then we will

450
00:17:09,750 --> 00:17:07,839
have successfully installed a new ata

451
00:17:11,669 --> 00:17:09,760
into the s1 trust and have the old atl

452
00:17:14,390 --> 00:17:11,679
on the lmc ready for return and

453
00:17:15,990 --> 00:17:14,400
refurbishment

454
00:17:17,829 --> 00:17:16,000
so when they're done there clay is going

455
00:17:19,429 --> 00:17:17,839
to grab that fixed grapple bar off the

456
00:17:20,549 --> 00:17:19,439
ata

457
00:17:22,470 --> 00:17:20,559
it's going to put it on his body

458
00:17:25,510 --> 00:17:22,480
restraint tether he'll translate down

459
00:17:26,710 --> 00:17:25,520
the payload bay down the

460
00:17:29,029 --> 00:17:26,720
station

461
00:17:31,350 --> 00:17:29,039
and install it on the bottom side of the

462
00:17:33,270 --> 00:17:31,360
new ata that they just installed

463
00:17:35,510 --> 00:17:33,280
they put it here as just a plate a place

464
00:17:39,990 --> 00:17:35,520
to temporarily stow it until it's needed

465
00:17:43,350 --> 00:17:41,830
so here's some mbl footage of rick

466
00:17:45,590 --> 00:17:43,360
installing that fixed grapple bar onto

467
00:17:53,669 --> 00:17:45,600
the bottom side of the new ata it's now

468
00:17:57,830 --> 00:17:55,750
so while rick is doing that clay is

469
00:17:59,990 --> 00:17:57,840
going to grab his foot restraint off the

470
00:18:01,909 --> 00:18:00,000
lmc and he's going to start setting up

471
00:18:05,590 --> 00:18:01,919
to do some tasks on dexter so you can

472
00:18:08,310 --> 00:18:06,789
and here's a view of what it'll look

473
00:18:09,590 --> 00:18:08,320
like outside the cupola windows and you

474
00:18:12,070 --> 00:18:09,600
can see the foot restraint flashing in

475
00:18:13,350 --> 00:18:12,080
the background that's clay at the lmc

476
00:18:14,950 --> 00:18:13,360
and the arms can start maneuvering to

477
00:18:17,270 --> 00:18:14,960
the columbus module to the exposed

478
00:18:19,350 --> 00:18:17,280
facility on the end of the columbus

479
00:18:21,190 --> 00:18:19,360
so clay will grab that full restraint he

480
00:18:29,190 --> 00:18:21,200
will translate out to columbus himself

481
00:18:32,549 --> 00:18:30,870
and once both clay and the arm get to

482
00:18:34,390 --> 00:18:32,559
the uh the columbus

483
00:18:36,470 --> 00:18:34,400
clay will install the four restraint

484
00:18:38,150 --> 00:18:36,480
onto the arm you see the arm medium

485
00:18:39,909 --> 00:18:38,160
there and he'll get in that foot

486
00:18:41,750 --> 00:18:39,919
restraint and he's gonna

487
00:18:44,950 --> 00:18:41,760
disconnect the lightweight adapter

488
00:18:46,310 --> 00:18:44,960
plated assembly our lawapa the lapa is a

489
00:18:48,870 --> 00:18:46,320
big plate that we use to hold other

490
00:18:50,630 --> 00:18:48,880
things onto the columbus module so he'll

491
00:18:52,710 --> 00:18:50,640
unbolt it and the arm is going to fly

492
00:18:54,150 --> 00:18:52,720
him back to the payload bay

493
00:18:57,669 --> 00:18:54,160
here's another view of what that might

494
00:19:00,950 --> 00:18:57,679
look like from the cupola windows

495
00:19:03,430 --> 00:19:00,960
you can see the loap of flashing in blue

496
00:19:04,950 --> 00:19:03,440
so the arm will fly him fly clay in to

497
00:19:06,470 --> 00:19:04,960
back to the to the lmc actually it's

498
00:19:08,390 --> 00:19:06,480
going to fly him upside down because

499
00:19:10,870 --> 00:19:08,400
he's going to bolt the lopa to the

500
00:19:12,710 --> 00:19:10,880
bottom of the lmc right underneath where

501
00:19:20,549 --> 00:19:12,720
the old ammonia tank is bolted to the

502
00:19:24,390 --> 00:19:22,310
so here's some animation of showing him

503
00:19:26,470 --> 00:19:24,400
do that and here's some mbl footage what

504
00:19:35,510 --> 00:19:26,480
that looks like with clay upside down

505
00:19:38,470 --> 00:19:37,029
once clay has completed that task and

506
00:19:40,470 --> 00:19:38,480
rick will be there helping him get it in

507
00:19:43,590 --> 00:19:40,480
place at the lmc

508
00:19:45,750 --> 00:19:43,600
the arm's gonna fly clay over to dexter

509
00:19:47,190 --> 00:19:45,760
where he's gonna install a camera unit

510
00:19:48,950 --> 00:19:47,200
dexter has one camera on it right now

511
00:19:50,310 --> 00:19:48,960
and has a place for two so we'll take

512
00:19:52,549 --> 00:19:50,320
that camera that's flashing in blue and

513
00:19:53,830 --> 00:19:52,559
he'll install in a second location

514
00:19:55,350 --> 00:19:53,840
here's some mbl footage of him

515
00:19:58,070 --> 00:19:55,360
installing that camera to the white box

516
00:20:01,750 --> 00:19:59,510
that'll give dexter two cameras that he

517
00:20:03,029 --> 00:20:01,760
can use for future operations

518
00:20:04,630 --> 00:20:03,039
once he's done with that the arm is

519
00:20:05,990 --> 00:20:04,640
going to line up just a little bit where

520
00:20:07,830 --> 00:20:06,000
he's going to remove a thermal blanket

521
00:20:09,510 --> 00:20:07,840
off dexter that's no longer needed and

522
00:20:16,630 --> 00:20:09,520
he'll put that blanket in the bag that

523
00:20:19,430 --> 00:20:17,990
and once he has that camera installed

524
00:20:20,950 --> 00:20:19,440
and the blanket removed from dexter the

525
00:20:23,430 --> 00:20:20,960
arm will fly him back to the columbus

526
00:20:25,110 --> 00:20:23,440
module where he got on the arm

527
00:20:27,190 --> 00:20:25,120
and he's going to get off the arm take

528
00:20:31,990 --> 00:20:27,200
his footwork strain off and clean up the

529
00:20:35,430 --> 00:20:33,270
and he'll take his foot restraint back

530
00:20:37,190 --> 00:20:35,440
to node 2 and install it and leave it

531
00:20:50,789 --> 00:20:37,200
there

532
00:20:53,830 --> 00:20:52,230
while clay is doing these tests on

533
00:20:54,950 --> 00:20:53,840
dexter now this is a one-person

534
00:20:57,990 --> 00:20:54,960
operation

535
00:20:59,909 --> 00:20:58,000
rick has a few tasks of his own

536
00:21:01,110 --> 00:20:59,919
he'll be heading back to the lab the u.s

537
00:21:03,190 --> 00:21:01,120
lab module

538
00:21:05,190 --> 00:21:03,200
and there's a camera on a post on the

539
00:21:06,710 --> 00:21:05,200
lab and that camera has a light on it

540
00:21:08,230 --> 00:21:06,720
that's burned out

541
00:21:09,510 --> 00:21:08,240
so rick's gonna come up to that camera

542
00:21:10,950 --> 00:21:09,520
he's gonna remove the old light and

543
00:21:18,149 --> 00:21:10,960
install a new one see that light

544
00:21:21,590 --> 00:21:19,590
and here's some mbl footage of rick

545
00:21:27,190 --> 00:21:21,600
installing that light on the camera

546
00:21:29,590 --> 00:21:28,470
once he's done with that he'll head back

547
00:21:30,870 --> 00:21:29,600
to the airlock and he'll put the old

548
00:21:32,789 --> 00:21:30,880
light in the air lock and he's going to

549
00:21:34,470 --> 00:21:32,799
grab two more of those radiator grapple

550
00:21:36,310 --> 00:21:34,480
fixture stow which beams

551
00:21:37,669 --> 00:21:36,320
so on eva2 they installed two of those

552
00:21:39,669 --> 00:21:37,679
on the port side

553
00:21:41,510 --> 00:21:39,679
rick will come to the starboard radiator

554
00:21:43,510 --> 00:21:41,520
beam but at the time i come to the top

555
00:21:45,590 --> 00:21:43,520
side of it and install those two ready

556
00:21:49,430 --> 00:21:45,600
to grab fixture stowage beams

557
00:21:53,590 --> 00:21:50,870
once he's done with that he will head

558
00:21:56,070 --> 00:21:53,600
back to esp2 where he's going to grab a

559
00:21:58,070 --> 00:21:56,080
worksite extender worksite interface

560
00:21:59,510 --> 00:21:58,080
extender a wiff extender this basically

561
00:22:01,350 --> 00:21:59,520
is a device that allows us to get more

562
00:22:03,029 --> 00:22:01,360
reach with our foot restraints

563
00:22:05,430 --> 00:22:03,039
he's going to remove it from esp2 and

564
00:22:08,950 --> 00:22:05,440
take it over to the mobile base system

565
00:22:13,110 --> 00:22:10,950
and the next flight sts-132 is going to

566
00:22:14,390 --> 00:22:13,120
use the wiff extender in that location

567
00:22:25,990 --> 00:22:14,400
so this is another get ahead for the

568
00:22:29,190 --> 00:22:27,430
and rick and clay should be finishing up

569
00:22:30,950 --> 00:22:29,200
about the same time doing all these

570
00:22:34,149 --> 00:22:30,960
tasks so this will they'll head back to

571
00:22:45,830 --> 00:22:34,159
the joint airlock and finish up eva3 and

572
00:22:48,950 --> 00:22:47,350
so i'd like to take a moment also to

573
00:22:50,230 --> 00:22:48,960
thank my team for helping put these dvas

574
00:22:51,430 --> 00:22:50,240
together doing a whole lot of work over

575
00:22:53,669 --> 00:22:51,440
the last year

576
00:22:55,830 --> 00:22:53,679
john milorski and shelly mulhern and

577
00:22:57,190 --> 00:22:55,840
sabrina gilmore jordan lindsey and jay

578
00:23:00,230 --> 00:22:57,200
burger have all helped out a whole lot

579
00:23:03,430 --> 00:23:02,070
that's all i have okay we'll take some

580
00:23:04,549 --> 00:23:03,440
questions from here at the johnson space

581
00:23:06,830 --> 00:23:04,559
center first then we'll go down to the

582
00:23:10,230 --> 00:23:06,840
other centers and

583
00:23:11,590 --> 00:23:10,240
headquarters okay

584
00:23:13,430 --> 00:23:11,600
anybody over here

585
00:23:14,950 --> 00:23:13,440
okay then we'll go to the kennedy space

586
00:23:23,510 --> 00:23:14,960
center then in florida and see if there

587
00:23:23,520 --> 00:23:28,710
okay we'll go to headquarters next then

588
00:23:32,789 --> 00:23:30,470
thanks it's uh tarek malek from

589
00:23:34,630 --> 00:23:32,799
space.com space news and i just had a

590
00:23:35,669 --> 00:23:34,640
question about the ata replacement i'm

591
00:23:37,190 --> 00:23:35,679
just

592
00:23:39,190 --> 00:23:37,200
curious if there are any um i guess

593
00:23:40,710 --> 00:23:39,200
safety precautions that the

594
00:23:42,630 --> 00:23:40,720
spacewalkers have to take care of when

595
00:23:44,470 --> 00:23:42,640
they're handling the ammonia tank

596
00:23:46,789 --> 00:23:44,480
assembly uh stuff they've maybe they

597
00:23:47,510 --> 00:23:46,799
learned from the last ata replacement

598
00:23:48,710 --> 00:23:47,520
and

599
00:23:49,990 --> 00:23:48,720
if this old one is going to be

600
00:23:53,190 --> 00:23:50,000
refurbished and flown back to the

601
00:23:57,830 --> 00:23:55,070
well they actually did learn a lot from

602
00:23:59,029 --> 00:23:57,840
sts-128 that did the other ammonia tank

603
00:24:00,470 --> 00:23:59,039
so it's really good to see them do that

604
00:24:02,070 --> 00:24:00,480
it's kind of a nice dry rehearsal for

605
00:24:04,549 --> 00:24:02,080
for our mission

606
00:24:07,029 --> 00:24:04,559
it's a big oru so it's very heavy

607
00:24:09,350 --> 00:24:07,039
uh we do practice a lot to use foot

608
00:24:10,870 --> 00:24:09,360
restraints to get a stable work platform

609
00:24:13,750 --> 00:24:10,880
uh the crew is trying to always maintain

610
00:24:14,950 --> 00:24:13,760
good solid control over it um

611
00:24:17,830 --> 00:24:14,960
and as far as that being filled with

612
00:24:19,590 --> 00:24:17,840
ammonia the

613
00:24:21,750 --> 00:24:19,600
the internal side of it is filled with

614
00:24:23,029 --> 00:24:21,760
ammonia but the the qd's that they

615
00:24:24,950 --> 00:24:23,039
operate the quick disconnects where they

616
00:24:26,149 --> 00:24:24,960
actually the ev crew interfaces

617
00:24:28,230 --> 00:24:26,159
it's not doesn't have a money on the

618
00:24:30,470 --> 00:24:28,240
backside of that so it should be pretty

619
00:24:31,909 --> 00:24:30,480
safe nothing too extremely hazardous but

620
00:24:34,070 --> 00:24:31,919
again it is full of ammonia so we do

621
00:24:35,590 --> 00:24:34,080
take up precautions

622
00:24:37,350 --> 00:24:35,600
we do have those in place if we need to

623
00:24:39,830 --> 00:24:37,360
use them

624
00:24:41,110 --> 00:24:39,840
and the old ata will be flown back

625
00:24:43,190 --> 00:24:41,120
for refurbished and refilling with

626
00:24:49,029 --> 00:24:43,200
pneumonia and flowing back on one of the

627
00:24:52,230 --> 00:24:50,390
okay i think that's it from nasa

628
00:24:54,950 --> 00:24:52,240
headquarters

629
00:24:57,110 --> 00:24:54,960
bill you got one

630
00:25:00,390 --> 00:24:57,120
well yeah let's ask you a generic uh

631
00:25:02,230 --> 00:25:00,400
question bill harwood cbs news um these

632
00:25:03,669 --> 00:25:02,240
don't look like they're overly complex

633
00:25:05,190 --> 00:25:03,679
place walks but they're obviously

634
00:25:07,269 --> 00:25:05,200
tightly timelined and a lot of

635
00:25:10,710 --> 00:25:07,279
interrelated activities i mean how do

636
00:25:12,230 --> 00:25:10,720
you assess the complexity of it and the

637
00:25:14,470 --> 00:25:12,240
just the overall workload to get all

638
00:25:16,549 --> 00:25:14,480
this done well that's a really good

639
00:25:18,630 --> 00:25:16,559
assessment the the tasks themselves are

640
00:25:20,470 --> 00:25:18,640
not very complicated uh we're just

641
00:25:22,310 --> 00:25:20,480
basically moving some boxes around and

642
00:25:24,870 --> 00:25:22,320
bolting them in place but the amount of

643
00:25:27,190 --> 00:25:24,880
tank it is large it's 760 pounds so it's

644
00:25:29,269 --> 00:25:27,200
a very large mass the ev crew cannot

645
00:25:31,110 --> 00:25:29,279
move it by itself therefore we have to

646
00:25:33,110 --> 00:25:31,120
use the robotic arm

647
00:25:35,590 --> 00:25:33,120
this involves us using the arm

648
00:25:38,230 --> 00:25:35,600
for all three evas and so whenever we

649
00:25:39,990 --> 00:25:38,240
tie the arm to the eva crew it increases

650
00:25:41,909 --> 00:25:40,000
the complexity especially as far as

651
00:25:43,830 --> 00:25:41,919
timeline goes so we spent a lot of time

652
00:25:45,510 --> 00:25:43,840
choreographing things in the mbl

653
00:25:47,590 --> 00:25:45,520
and the virtual reality lab to make sure

654
00:25:49,110 --> 00:25:47,600
that we are time stuff out to where the

655
00:25:50,390 --> 00:25:49,120
arm is not waiting on the eva crew or

656
00:25:51,909 --> 00:25:50,400
the eva crew is not wearing the arm too

657
00:25:53,990 --> 00:25:51,919
much so the hardest part will be that

658
00:25:55,750 --> 00:25:54,000
correlation between the two

659
00:25:58,070 --> 00:25:55,760
did these evas everything do you guys

660
00:25:59,990 --> 00:25:58,080
have anything in the in the in the bag

661
00:26:01,669 --> 00:26:00,000
for get-aheads beyond what you told us

662
00:26:02,789 --> 00:26:01,679
about or do you really or do you think

663
00:26:04,310 --> 00:26:02,799
these are going to really fill up the

664
00:26:05,909 --> 00:26:04,320
time you got allowed

665
00:26:08,149 --> 00:26:05,919
we we have a few small get ahead you

666
00:26:10,390 --> 00:26:08,159
know we're getting towards the end of

667
00:26:12,390 --> 00:26:10,400
the shuttle flight going station towards

668
00:26:14,149 --> 00:26:12,400
the end of assembly station so

669
00:26:15,830 --> 00:26:14,159
we actually don't have a whole lot of

670
00:26:18,789 --> 00:26:15,840
get-aheads but we have a few in place

671
00:26:20,710 --> 00:26:18,799
that we can do uh at various evas

672
00:26:22,870 --> 00:26:20,720
just one more just because rick and clay

673
00:26:25,190 --> 00:26:22,880
have obviously worked together before

674
00:26:27,190 --> 00:26:25,200
um does that helped in training or is it

675
00:26:28,870 --> 00:26:27,200
is it something that that was years ago

676
00:26:30,710 --> 00:26:28,880
and it's like a different it's like a

677
00:26:32,149 --> 00:26:30,720
new flight you start from scratch oh no

678
00:26:33,669 --> 00:26:32,159
absolutely i think both of them having

679
00:26:35,909 --> 00:26:33,679
experience and both of them having

680
00:26:38,149 --> 00:26:35,919
worked before on actual evas has been

681
00:26:39,750 --> 00:26:38,159
great now those two from from day one

682
00:26:41,990 --> 00:26:39,760
started working together uh just

683
00:26:43,669 --> 00:26:42,000
perfectly so i think that's a real asset

684
00:26:46,710 --> 00:26:43,679
to this flight is their experience and

685
00:26:48,630 --> 00:26:46,720
especially their experience together

686
00:26:49,990 --> 00:26:48,640
okay over here yeah eric berger with the

687
00:26:51,830 --> 00:26:50,000
houston chronicle i think you mentioned

688
00:26:53,669 --> 00:26:51,840
that the emotion excuse me the ammonia

689
00:26:55,669 --> 00:26:53,679
tank assembly was roughly the size of a

690
00:26:57,590 --> 00:26:55,679
first generation smart car

691
00:26:58,950 --> 00:26:57,600
yes okay roughly

692
00:27:00,549 --> 00:26:58,960
huge smart car is a little bigger money

693
00:27:03,110 --> 00:27:00,559
tank's a little heavier this houston

694
00:27:07,510 --> 00:27:03,120
texas the petroleum capital of the world

695
00:27:11,590 --> 00:27:07,520
is that like a vw bug or something

696
00:27:16,070 --> 00:27:13,110
okay i think that's it from here one

697
00:27:20,630 --> 00:27:18,070
uh just one more claim from question

698
00:27:22,630 --> 00:27:20,640
from mark kramer our producer

699
00:27:25,029 --> 00:27:22,640
in new york what the old

700
00:27:26,389 --> 00:27:25,039
mmod shields why are they going back in

701
00:27:27,669 --> 00:27:26,399
and what were they there for in the

702
00:27:29,909 --> 00:27:27,679
first place

703
00:27:32,310 --> 00:27:29,919
those shields were on the airlock and so

704
00:27:33,510 --> 00:27:32,320
when the sts-129 flew up they took those

705
00:27:35,909 --> 00:27:33,520
shields off the airlock and they

706
00:27:37,430 --> 00:27:35,919
installed a fifth gas tank on top of the

707
00:27:38,789 --> 00:27:37,440
airlock okay so they're just not needed

708
00:27:40,149 --> 00:27:38,799
anymore right and they're big they're

709
00:27:41,830 --> 00:27:40,159
hard to fly down so we're flying them

710
00:27:43,750 --> 00:27:41,840
down the mplm that's why they left them

711
00:27:46,149 --> 00:27:43,760
for us to do thank you that'll do it

712
00:27:47,750 --> 00:27:46,159
okay that's it from here that'll wrap up

713
00:27:49,350 --> 00:27:47,760
today's briefing thanks a lot dave

714
00:27:50,870 --> 00:27:49,360
coming up next here on nasa tv we will

715
00:27:52,549 --> 00:27:50,880
have the b-roll feed taking a look at

716
00:27:54,630 --> 00:27:52,559
all the different animation and video

717
00:27:56,710 --> 00:27:54,640
file footage for this upcoming mission

718
00:27:58,470 --> 00:27:56,720
and then coming up at 12 p.m central

719
00:28:00,310 --> 00:27:58,480
time we will have a nasa education

720
00:28:01,750 --> 00:28:00,320
overview here on nasa tv we will bring

721
00:28:04,070 --> 00:28:01,760
that to you live from here at the

722
00:28:07,190 --> 00:28:04,080
johnson space center and then at 1 pm

723
00:28:08,389 --> 00:28:07,200
central time the entire crew of sts-131

724
00:28:09,909 --> 00:28:08,399
will be here to take questions from the

725
00:28:12,789 --> 00:28:09,919
media and we will also broadcast that

726
00:28:14,149 --> 00:28:12,799
live here on nasa tv as well as always

727
00:28:15,510 --> 00:28:14,159
for the latest information on this

728
00:28:18,990 --> 00:28:15,520
mission or to learn more you can always
