00:00:01,936 --> 00:00:04,246
Greetings from Mission
Control Houston and welcome

2
00:00:04,246 --> 00:00:05,416
to this Friday edition

3
00:00:05,416 --> 00:00:07,256
of International
Space Station Update.

4
00:00:08,436 --> 00:00:09,596
Joining us here inside

5
00:00:09,596 --> 00:00:11,786
of the International Space
Station Flight Control Room

6
00:00:11,786 --> 00:00:13,876
at the Johnson Space
Center in Houston, Texas,

7
00:00:14,336 --> 00:00:15,726
where the Orbit Two
team is currently

8
00:00:15,726 --> 00:00:18,706
on console monitoring all
the systems onboard this

9
00:00:18,706 --> 00:00:19,636
orbiting laboratory.

10
00:00:20,936 --> 00:00:23,956
Team being led right now by
Flight Director Chris Edelen.

11
00:00:24,386 --> 00:00:26,896
He is joined at the
Capcom position right now

12
00:00:26,896 --> 00:00:29,686
by Lucia McCullough serving
as the communication link

13
00:00:29,686 --> 00:00:32,126
between all the controllers
down here on the ground

14
00:00:32,356 --> 00:00:34,006
and the astronauts up in space.

15
00:00:35,656 --> 00:00:37,556
Those astronauts
right now are the crew

16
00:00:37,556 --> 00:00:41,296
of Expedition 32
currently comprised

17
00:00:41,296 --> 00:00:43,616
of a six person team being led

18
00:00:43,616 --> 00:00:45,606
by Russian cosmonaut
Gennady Padalka,

19
00:00:45,706 --> 00:00:48,016
there on the right
side in the front row.

20
00:00:48,386 --> 00:00:54,066
Behind him are Soyuz TMA-04M
crewmates Joe Acaba over his...

21
00:00:54,266 --> 00:00:57,886
off to the left, and then
Russian cosmonaut Sergei Revin

22
00:00:57,886 --> 00:00:58,686
all the way on the right.

23
00:00:59,086 --> 00:01:02,116
Then on the left side we have
our three newest crew members

24
00:01:02,116 --> 00:01:03,746
onboard the International
Space Station.

25
00:01:04,226 --> 00:01:07,456
Starting on the left,
Japanese astronaut Aki Hoshide

26
00:01:07,456 --> 00:01:08,976
on his second flight to space.

27
00:01:09,516 --> 00:01:10,736
Right there in the middle,

28
00:01:10,736 --> 00:01:13,696
Yuri Malenchenko a veteran
astronaut on his fifth flight.

29
00:01:14,096 --> 00:01:16,366
And then finally NASA
astronaut Suni Williams

30
00:01:16,366 --> 00:01:20,206
on her second flight, second
long-duration mission.

31
00:01:21,476 --> 00:01:24,746
It's been a very busy week
onboard the International Space

32
00:01:24,746 --> 00:01:28,556
Station with a lot of robotics
activity and maintenance work

33
00:01:28,556 --> 00:01:34,056
and a slew of preparation work
for the spacewalk undertaken

34
00:01:34,056 --> 00:01:37,866
by NASA astronaut Suni Williams
and Aki Hoshide yesterday.

35
00:01:38,676 --> 00:01:42,046
Starting off on Monday
we had Joe Acaba working

36
00:01:42,046 --> 00:01:44,306
with Robonaut inside of
the Destiny laboratory.

37
00:01:44,766 --> 00:01:47,476
He was working to set
up the humanoid robot

38
00:01:47,476 --> 00:01:49,866
as it was then commanded
from controllers

39
00:01:49,866 --> 00:01:50,936
down here on the ground.

40
00:01:51,556 --> 00:01:53,236
Robonaut continuing
to go through a number

41
00:01:53,236 --> 00:01:58,416
of different checkouts
and exercises as they look

42
00:01:58,456 --> 00:01:59,936
to improve his dexterity

43
00:01:59,936 --> 00:02:02,766
and then functions onboard the
station eventually becoming a

44
00:02:02,766 --> 00:02:06,986
permanent addition to many
of the crew activities taking

45
00:02:06,986 --> 00:02:09,016
over some of the more
menial tasks like cleaning

46
00:02:09,016 --> 00:02:11,326
and taking air readings
from these crew members.

47
00:02:11,956 --> 00:02:14,786
Aside from that Robonaut work
on Monday, Joe Acaba was working

48
00:02:14,786 --> 00:02:18,336
to transfer some cargo from
the Japanese HTV vehicle,

49
00:02:18,786 --> 00:02:22,466
one of the numerous unmanned
cargo crafts currently docked

50
00:02:22,466 --> 00:02:23,856
to the International
Space Station.

51
00:02:24,726 --> 00:02:27,856
Meanwhile, his fellow NASA
astronaut Suni Williams is doing

52
00:02:27,856 --> 00:02:32,306
a check out on her SAFER
devices, SAFER standing

53
00:02:32,306 --> 00:02:34,716
for the Simplified
Aid For EVA Rescue.

54
00:02:35,276 --> 00:02:38,146
It's a small self-contained,
basically a jet pack

55
00:02:38,496 --> 00:02:41,606
that these astronauts wear
whenever they're outside the

56
00:02:41,606 --> 00:02:44,666
station airlocks doing
spacewalks and serves as kind

57
00:02:44,666 --> 00:02:46,096
of a safety net device.

58
00:02:46,276 --> 00:02:47,826
Should they become
untethered and start

59
00:02:47,826 --> 00:02:51,366
to float away they can always
fire that jet pack and get back

60
00:02:51,496 --> 00:02:54,386
to the safe portion
of the space station.

61
00:02:54,826 --> 00:02:58,166
She's also going over some of
the procedures for her spacewalk

62
00:02:58,196 --> 00:03:00,316
which again took place
yesterday on Thursday.

63
00:03:00,986 --> 00:03:03,976
Aside from that she was doing
a biomedical experiment working

64
00:03:03,976 --> 00:03:05,736
with the station's
SLAMMD device,

65
00:03:06,086 --> 00:03:08,966
which stands the Space
Linear Acceleration Mass

66
00:03:08,966 --> 00:03:09,886
Measurement Device.

67
00:03:10,306 --> 00:03:12,116
Doing a control run is one

68
00:03:12,116 --> 00:03:15,296
of the only devices onboard
the station that is able

69
00:03:15,296 --> 00:03:19,076
to measure a crew members'
mass given that they are

70
00:03:19,076 --> 00:03:20,626
in the microgravity environment,

71
00:03:20,806 --> 00:03:26,576
something like a scale is not
very useful so SLAMMD again part

72
00:03:26,576 --> 00:03:28,306
of the ongoing research

73
00:03:28,306 --> 00:03:31,406
to constantly monitor crew
members' bodies throughout these

74
00:03:31,406 --> 00:03:32,626
microgravity flights.

75
00:03:34,806 --> 00:03:39,326
Aki Hoshide was checking out
his own SAFER device on Monday

76
00:03:39,326 --> 00:03:41,626
and also going through
a procedure review

77
00:03:41,626 --> 00:03:44,516
with Suni Williams and also
transferring some cargo

78
00:03:44,516 --> 00:03:47,856
over from that Japanese HTV
vehicle along with Joe Acaba.

79
00:03:48,756 --> 00:03:51,206
Meanwhile, our Russian
cosmonauts onboard on Monday,

80
00:03:51,206 --> 00:03:55,196
Gennady Padalka, the Expedition
32 commander, was doing a study

81
00:03:55,196 --> 00:03:57,166
of the veins in his lower limbs

82
00:03:57,536 --> 00:03:59,166
and also doing some
replacement work

83
00:03:59,166 --> 00:04:01,486
on the Russian Elektron system.

84
00:04:01,486 --> 00:04:04,196
It's one of the oxygen
generation systems onboard

85
00:04:04,196 --> 00:04:05,466
International Space Station.

86
00:04:06,256 --> 00:04:10,126
Meanwhile, cosmonaut Sergei
Revin was unloading some items

87
00:04:10,126 --> 00:04:11,956
from the 48 Progress vehicle

88
00:04:12,066 --> 00:04:15,916
which is the unmanned Russian
cargo craft currently docked

89
00:04:15,916 --> 00:04:17,306
to the International
Space Station.

90
00:04:17,696 --> 00:04:19,646
You can see the full
station complex

91
00:04:19,646 --> 00:04:24,206
and all the visiting vehicles
right now, two Soyuz crew crafts

92
00:04:24,206 --> 00:04:27,166
and then three unmanned
robotic cargo crafts.

93
00:04:27,616 --> 00:04:29,766
The HTV-3 all the way
on the left there,

94
00:04:29,766 --> 00:04:32,096
the Japanese vehicle,
the Progress 48,

95
00:04:32,126 --> 00:04:33,586
the Russian vehicle
there in the middle,

96
00:04:33,956 --> 00:04:35,006
all the way at the aft end

97
00:04:35,006 --> 00:04:37,396
of the station the
ATV-3 vehicle built

98
00:04:37,396 --> 00:04:39,056
by the European Space Agency.

99
00:04:39,886 --> 00:04:42,886
So Revin was unloading some
items from that 48 Progress

100
00:04:42,886 --> 00:04:46,246
and also updating the station's
inventory management system,

101
00:04:46,806 --> 00:04:49,746
also working on the Russian
Pneumocard experiment

102
00:04:49,746 --> 00:04:54,076
which is a study that looks
to track the adaptation

103
00:04:54,076 --> 00:04:55,846
of the cardiovascular
system inside

104
00:04:55,846 --> 00:04:57,706
of these crew members
during their long-duration

105
00:04:57,706 --> 00:04:59,076
microgravity exposure.

106
00:04:59,926 --> 00:05:03,556
And meanwhile, Yuri Malenchenko
was transferring a few items

107
00:05:03,556 --> 00:05:06,576
and also draining the Urine
Processor Assembly recycle tank

108
00:05:06,906 --> 00:05:08,356
transferring some
of that wastewater

109
00:05:08,356 --> 00:05:10,376
over to the ATV vehicle.

110
00:05:11,096 --> 00:05:13,356
Moving on to Tuesday,
Joe Acaba was back

111
00:05:13,356 --> 00:05:16,046
in the Destiny laboratory
powering up Robonaut

112
00:05:16,426 --> 00:05:19,096
and then stowing him away
following the completion

113
00:05:19,096 --> 00:05:21,516
of two days of robotic ops
down here on the ground.

114
00:05:22,096 --> 00:05:24,736
He was also installing
a contingency jumper.

115
00:05:25,196 --> 00:05:29,086
A number of jumpers were
installed prior to the spacewalk

116
00:05:29,156 --> 00:05:34,286
which was looking to replace a
failed MBSU power relay system.

117
00:05:34,906 --> 00:05:38,746
So this procedure that
Acaba took on Tuesday was

118
00:05:39,126 --> 00:05:43,226
to supply power to various loads
along the station's external

119
00:05:43,226 --> 00:05:46,546
truss in the event
of a loss of power.

120
00:05:47,206 --> 00:05:50,346
So moving on Williams,
Suni Williams,

121
00:05:50,346 --> 00:05:53,496
was completing a pre-spacewalk
medical exam on Tuesday

122
00:05:53,496 --> 00:05:59,426
and also doing an Exploration
Design Challenge looking

123
00:05:59,426 --> 00:06:02,176
to highlight radiation research
being conducted onboard the

124
00:06:02,176 --> 00:06:03,386
International Space Station.

125
00:06:03,926 --> 00:06:06,046
She was joined in
that by Aki Hoshide

126
00:06:06,046 --> 00:06:09,156
who was also doing his own
pre-spacewalk medical exam

127
00:06:09,496 --> 00:06:12,416
and also going through and doing
some final procedure updates

128
00:06:12,746 --> 00:06:14,956
for all their EVA tasks.

129
00:06:16,306 --> 00:06:21,086
Meanwhile on Tuesday, Gennady
Padalka was doing another

130
00:06:21,816 --> 00:06:25,056
medical experiment looking to
study orthostatic stability

131
00:06:25,536 --> 00:06:30,126
in these astronauts which
has some direct implications

132
00:06:30,126 --> 00:06:33,296
and looking at how well
these astronauts are able

133
00:06:33,296 --> 00:06:35,596
to stand upright and how
their balance is affected

134
00:06:35,596 --> 00:06:39,096
after spending long durations
in the weightless environment.

135
00:06:39,566 --> 00:06:42,046
Padalka was also doing
some routine replacement

136
00:06:42,046 --> 00:06:44,516
of a few components inside
of the Russian toilet system.

137
00:06:45,796 --> 00:06:48,086
Sergei Revin also
joining Padalka

138
00:06:48,086 --> 00:06:51,416
in that orthostatic stability
evaluation doing an on-orbit

139
00:06:51,416 --> 00:06:54,976
hearing test while Yuri
Malenchenko was replacing a

140
00:06:54,976 --> 00:06:58,696
relay adapter inside of the
Zarya module and then standing

141
00:06:58,696 --> 00:07:02,746
by with Joe Acaba to review
some of those robotic procedures

142
00:07:02,746 --> 00:07:06,136
as Acaba was quarterbacking
the spacewalk on Thursday

143
00:07:06,136 --> 00:07:08,366
and controlling the
station's robotic arm.

144
00:07:09,176 --> 00:07:11,376
Wednesday was a half
duty day for the crew,

145
00:07:11,896 --> 00:07:15,826
Joe Acaba doing some final
review of those EVA procedures

146
00:07:16,146 --> 00:07:21,406
and then installing
another jumper cable.

147
00:07:21,406 --> 00:07:27,166
So again just in case power was
lost through any of these...

148
00:07:27,276 --> 00:07:30,786
from a failed MBSU install
they would still be able

149
00:07:30,786 --> 00:07:34,876
to maintain power to
vital station systems.

150
00:07:35,626 --> 00:07:39,126
Meanwhile, again in that half
duty day Suni Williams was

151
00:07:39,176 --> 00:07:41,946
preparing the equipment lock
and configuring all the tools

152
00:07:42,326 --> 00:07:45,106
that she and Aki would
need for their spacewalk.

153
00:07:45,606 --> 00:07:48,836
Aki meanwhile was holding
one last procedure review

154
00:07:48,836 --> 00:07:50,276
in a conference with the ground.

155
00:07:50,596 --> 00:07:51,456
You can see them inside

156
00:07:51,456 --> 00:07:55,346
of the Quest Airlock here
getting everything ready before

157
00:07:55,346 --> 00:07:57,546
they were going to step
out the following morning.

158
00:07:58,986 --> 00:08:01,906
Also on Wednesday, Gennady
Padalka was replacing a battery

159
00:08:01,906 --> 00:08:05,036
unit inside of the Zvezda
service module while Sergei

160
00:08:05,036 --> 00:08:07,886
Revin was inside Zvezda and
Zarya collecting a number

161
00:08:07,886 --> 00:08:12,616
of air samples and Yuri
Malenchenko doing an audit

162
00:08:12,616 --> 00:08:15,746
of the station medical
kits and doing his own runs

163
00:08:15,746 --> 00:08:18,526
of the Pneumocard
medical experiment.

164
00:08:19,466 --> 00:08:21,866
Moving on to Thursday,
yesterday all eyes were

165
00:08:21,866 --> 00:08:25,626
on spacewalkers Suni
Williams and Aki Hoshide

166
00:08:25,626 --> 00:08:27,316
as they conducted an 8 hour

167
00:08:27,316 --> 00:08:30,226
and 17 minute spacewalk
moving themselves

168
00:08:30,226 --> 00:08:31,186
in to the history books

169
00:08:31,186 --> 00:08:34,736
as it was the third longest
spacewalk in history.

170
00:08:35,466 --> 00:08:38,636
Their main task of replacing
a Main Bus Switching Unit

171
00:08:38,636 --> 00:08:41,876
on the S-Zero truss
was unsuccessful due

172
00:08:41,876 --> 00:08:43,256
to a troublesome bolt.

173
00:08:43,766 --> 00:08:49,476
So meanwhile teams are now
looking at coming up with ways

174
00:08:50,086 --> 00:08:52,516
to decide the next
course of action

175
00:08:52,516 --> 00:08:55,266
and then do a potential
follow-up of the spacewalk

176
00:08:55,266 --> 00:08:58,116
in the nearby future to
complete the task perhaps even

177
00:08:58,116 --> 00:08:59,266
as early as next week.

178
00:09:00,136 --> 00:09:04,046
And then today a lot of
that post-EVA work going on,

179
00:09:04,426 --> 00:09:07,966
Joe Acaba initiating a charge
on a number of the batteries

180
00:09:07,966 --> 00:09:09,486
that are used for
these spacewalks,

181
00:09:09,956 --> 00:09:12,106
also getting inside the suits

182
00:09:12,106 --> 00:09:15,946
and doing some relief valve
cycling preparing them, again,

183
00:09:15,946 --> 00:09:18,496
should they be needed for
a spacewalk early next week

184
00:09:18,496 --> 00:09:19,756
for Williams and Hoshide.

185
00:09:20,616 --> 00:09:23,586
Meanwhile, the two spacewalkers
doing some health status,

186
00:09:23,966 --> 00:09:26,576
health status checks
post-spacewalk.

187
00:09:27,256 --> 00:09:30,256
Williams was also working
to prepare the suits

188
00:09:30,256 --> 00:09:33,496
and photographing the gloves
and checking for any damage

189
00:09:34,266 --> 00:09:35,546
that may have occurred

190
00:09:35,546 --> 00:09:37,936
on the hands while those
astronauts were moving outside

191
00:09:37,936 --> 00:09:38,546
of the station.

192
00:09:39,066 --> 00:09:42,376
She was also going through an
EVA debrief with teams here

193
00:09:42,376 --> 00:09:45,446
on the ground along with
Joe Acaba and Aki Hoshide.

194
00:09:45,446 --> 00:09:50,766
Hoshide assisting in all
that post-EVA prep work

195
00:09:51,336 --> 00:09:55,016
and also having a few more tasks
onboard the station relocating

196
00:09:55,016 --> 00:09:56,916
some of the contingency
water containers,

197
00:09:57,266 --> 00:10:00,556
also taking some time out to
do a ham radio pass with the,

198
00:10:00,826 --> 00:10:02,626
some students in Mayen, Germany.

199
00:10:03,626 --> 00:10:06,706
And then our three Russian
cosmonauts today onboard the

200
00:10:06,706 --> 00:10:07,926
station, Padalka back

201
00:10:07,926 --> 00:10:10,216
at Pneumocard doing his
own runs again looking

202
00:10:10,216 --> 00:10:12,896
to study cardiovascular
adaptation

203
00:10:12,896 --> 00:10:15,186
of these astronauts during
long-duration spaceflights

204
00:10:15,546 --> 00:10:18,206
and also replacing a gas
liquid mixture filter.

205
00:10:18,826 --> 00:10:21,626
His two fellow Russian
cosmonauts, Sergei Revin

206
00:10:21,626 --> 00:10:24,566
and Yuri Malenchenko, are giving
the TVIS, or the Treadmill

207
00:10:24,566 --> 00:10:26,846
with Vibration Isolation
Stabilization,

208
00:10:27,226 --> 00:10:30,376
its six-month maintenance
today doing things

209
00:10:30,376 --> 00:10:33,426
like verifying the torque
on different fasteners

210
00:10:33,426 --> 00:10:36,026
and also lubricating a
number of the components.

211
00:10:36,136 --> 00:10:37,756
You can see the TVIS here.

212
00:10:37,756 --> 00:10:39,956
It's one of the many
work out devices

213
00:10:39,956 --> 00:10:42,346
that these astronauts have while
they're onboard the station

214
00:10:42,346 --> 00:10:46,446
to maintain things
like muscle mass

215
00:10:46,446 --> 00:10:49,756
and also fight off
losses in bone density.

216
00:10:50,446 --> 00:10:54,276
So as you can see very busy
week onboard the station

217
00:10:54,276 --> 00:10:57,456
with that spacewalk being
the centerpiece of all

218
00:10:57,456 --> 00:10:58,996
of this week's activities.

219
00:10:59,516 --> 00:11:02,306
Teams down here on the
ground continuing to look

220
00:11:02,306 --> 00:11:04,546
at just what went
wrong with getting

221
00:11:04,546 --> 00:11:07,966
that Main Bus Switching Unit
reinstalled and continuing
