1
00:00:05,269 --> 00:00:03,990
we start out our eva at the quest

2
00:00:07,749 --> 00:00:05,279
airlock

3
00:00:10,070 --> 00:00:07,759
jeff will be eb1 he'll be coming out

4
00:00:13,350 --> 00:00:10,080
wearing the red stripes

5
00:00:15,509 --> 00:00:13,360
and kate will hand out an oru bag to him

6
00:00:17,349 --> 00:00:15,519
that contains all the ida tools she'll

7
00:00:19,910 --> 00:00:17,359
egress and then they'll begin their

8
00:00:22,550 --> 00:00:19,920
translation forward out to the very

9
00:00:24,790 --> 00:00:22,560
forward end of the space station to do

10
00:00:26,790 --> 00:00:24,800
their work jeff will translate around

11
00:00:29,269 --> 00:00:26,800
the starboard side of the external

12
00:00:31,029 --> 00:00:29,279
stowage platform number two

13
00:00:33,590 --> 00:00:31,039
he'll wait there just a moment while

14
00:00:36,150 --> 00:00:33,600
kate finishes her initial translation

15
00:00:38,790 --> 00:00:36,160
adaptation and then translates over the

16
00:00:40,389 --> 00:00:38,800
top of the stowage platform out to pick

17
00:00:42,830 --> 00:00:40,399
up her foot restraint which is on the

18
00:00:45,670 --> 00:00:42,840
very forward edge of the

19
00:00:48,709 --> 00:00:45,680
esp2 once she's got that jeff will

20
00:00:51,830 --> 00:00:48,719
translate forward on the lab and that up

21
00:00:54,389 --> 00:00:51,840
over the top of the node 2 and finally

22
00:00:55,750 --> 00:00:54,399
on to the pma2 that's at the very

23
00:00:58,709 --> 00:00:55,760
forward end

24
00:01:01,750 --> 00:00:58,719
of the space station he'll position the

25
00:01:04,950 --> 00:01:01,760
oru bag on a couple of handrails that

26
00:01:06,469 --> 00:01:04,960
are right on the zenith side of the pma

27
00:01:08,710 --> 00:01:06,479
and then open the bag so that they've

28
00:01:10,950 --> 00:01:08,720
got access to their tools and the

29
00:01:12,789 --> 00:01:10,960
equipment

30
00:01:14,630 --> 00:01:12,799
in the meantime kate begins her

31
00:01:16,550 --> 00:01:14,640
translation she's going to translate up

32
00:01:19,350 --> 00:01:16,560
over the top of the lab

33
00:01:22,870 --> 00:01:19,360
and then forward onto the node 2

34
00:01:25,109 --> 00:01:22,880
and finally forward onto the pma2

35
00:01:26,469 --> 00:01:25,119
where she translates down toward the

36
00:01:29,109 --> 00:01:26,479
nader side

37
00:01:32,149 --> 00:01:29,119
and locates the socket where her foot

38
00:01:33,990 --> 00:01:32,159
restraint will go or work site interface

39
00:01:35,990 --> 00:01:34,000
once she has her foot restraint set up

40
00:01:37,109 --> 00:01:36,000
there she'll be able to access the

41
00:01:39,350 --> 00:01:37,119
cables

42
00:01:41,990 --> 00:01:39,360
that were pre-positioned by butch

43
00:01:43,990 --> 00:01:42,000
wilmore on a prior eva they're tied off

44
00:01:45,429 --> 00:01:44,000
to a in a bundle to a couple of

45
00:01:48,389 --> 00:01:45,439
handrails

46
00:01:50,630 --> 00:01:48,399
that are located on the pma

47
00:01:52,789 --> 00:01:50,640
while she's getting set up jeff will

48
00:01:55,350 --> 00:01:52,799
also get his foot restraint and get it

49
00:01:57,990 --> 00:01:55,360
set up it's currently located on the top

50
00:02:00,630 --> 00:01:58,000
of the columbus module he'll retrieve it

51
00:02:05,429 --> 00:02:00,640
from there and then move it down to his

52
00:02:09,190 --> 00:02:05,439
worksite interface on the pma which is

53
00:02:12,070 --> 00:02:09,200
more zenith and a little bit toward port

54
00:02:15,190 --> 00:02:12,080
from there each of them have access to

55
00:02:16,470 --> 00:02:15,200
be able to uh reach their cables

56
00:02:19,110 --> 00:02:16,480
jeff's cables have also been

57
00:02:21,350 --> 00:02:19,120
pre-positioned on a prior eva uh terry

58
00:02:23,190 --> 00:02:21,360
bertz left two bundles of cables there

59
00:02:24,869 --> 00:02:23,200
for him to access

60
00:02:26,710 --> 00:02:24,879
once they get into their foot restraints

61
00:02:28,470 --> 00:02:26,720
they can attach their adjustable

62
00:02:31,589 --> 00:02:28,480
equipment tethers

63
00:02:34,150 --> 00:02:31,599
loosely to the ida

64
00:02:35,830 --> 00:02:34,160
kate has one adjustable tether and in

65
00:02:38,070 --> 00:02:35,840
order to be able to reach between the

66
00:02:39,830 --> 00:02:38,080
handrail and the ida 2

67
00:02:41,589 --> 00:02:39,840
jeff actually has two

68
00:02:43,030 --> 00:02:41,599
tethers in series

69
00:02:45,110 --> 00:02:43,040
when they're in position they'll give

70
00:02:48,790 --> 00:02:45,120
the go to the robotics operator on the

71
00:02:50,390 --> 00:02:48,800
ground to release the ida 2 and back the

72
00:02:52,790 --> 00:02:50,400
dexter arm away

73
00:02:54,550 --> 00:02:52,800
at this point the crew has

74
00:02:56,869 --> 00:02:54,560
complete control of the ida they'll

75
00:02:59,830 --> 00:02:56,879
cinch the tethers down into place and

76
00:03:00,869 --> 00:02:59,840
then they'll begin mating the cables

77
00:03:03,430 --> 00:03:00,879
this is

78
00:03:05,350 --> 00:03:03,440
kate's cable configuration on the nader

79
00:03:07,990 --> 00:03:05,360
side here we see her at the neutral

80
00:03:09,350 --> 00:03:08,000
buoyancy laboratory practicing those

81
00:03:11,509 --> 00:03:09,360
cable mates

82
00:03:13,910 --> 00:03:11,519
and while she's mating her cables on the

83
00:03:16,790 --> 00:03:13,920
nader side jeff is mating his on the

84
00:03:19,030 --> 00:03:16,800
zenith side he has three cables to

85
00:03:20,309 --> 00:03:19,040
initially mate these cables are

86
00:03:23,589 --> 00:03:20,319
providing

87
00:03:26,470 --> 00:03:23,599
heater power to the docking adapter as

88
00:03:28,149 --> 00:03:26,480
well as the hook drive power and the

89
00:03:30,949 --> 00:03:28,159
sensor power

90
00:03:34,149 --> 00:03:30,959
these switches will be commanded by the

91
00:03:36,789 --> 00:03:34,159
internal crew member iv crew member talk

92
00:03:40,390 --> 00:03:36,799
will work at the ida control panel which

93
00:03:43,190 --> 00:03:40,400
is in the node 2 pressurized volume

94
00:03:45,190 --> 00:03:43,200
as he operates the switches it commands

95
00:03:48,229 --> 00:03:45,200
the hooks that are on the docking

96
00:03:50,710 --> 00:03:48,239
adapter to extend out rotate around and

97
00:03:53,030 --> 00:03:50,720
engage the passive hooks that are on the

98
00:03:54,949 --> 00:03:53,040
pressurized mated adapter

99
00:03:56,710 --> 00:03:54,959
there's two sets of hooks and while they

100
00:03:58,710 --> 00:03:56,720
drive the first set of hooks the crew

101
00:04:00,470 --> 00:03:58,720
needs to remain still but during the

102
00:04:03,110 --> 00:04:00,480
second drive it's stable enough that

103
00:04:05,589 --> 00:04:03,120
they can begin work uh installing a

104
00:04:08,710 --> 00:04:05,599
cover on the hemi reflector that's on

105
00:04:10,470 --> 00:04:08,720
the nadir part of the pma2

106
00:04:13,270 --> 00:04:10,480
then they're into their final cable

107
00:04:15,990 --> 00:04:13,280
mates these spinal cable configurations

108
00:04:19,110 --> 00:04:16,000
remove the power from the hooks that

109
00:04:22,550 --> 00:04:19,120
we're driving to engage the pma and

110
00:04:24,310 --> 00:04:22,560
provide visiting vehicle hook power

111
00:04:26,629 --> 00:04:24,320
here you see jeff working in the neutral

112
00:04:29,189 --> 00:04:26,639
buoyancy laboratory he's removing a

113
00:04:31,909 --> 00:04:29,199
couple of jumpers that are required to

114
00:04:34,150 --> 00:04:31,919
do his final cable mating once the

115
00:04:35,749 --> 00:04:34,160
cables are mated they have some

116
00:04:37,670 --> 00:04:35,759
outfitting to do

117
00:04:40,390 --> 00:04:37,680
first they'll be covering up the h

118
00:04:43,830 --> 00:04:40,400
fixture that the dexter robot arm was

119
00:04:46,629 --> 00:04:43,840
holding on to then there is a another

120
00:04:49,749 --> 00:04:46,639
hemi reflector that is on the

121
00:04:51,749 --> 00:04:49,759
pma they'll install a cover over the top

122
00:04:55,189 --> 00:04:51,759
of it and then move the tether that was

123
00:04:57,909 --> 00:04:55,199
holding that cover in place up to

124
00:05:00,870 --> 00:04:57,919
tether to the large protective cover

125
00:05:02,550 --> 00:05:00,880
that's covering the ida ii that was in

126
00:05:03,590 --> 00:05:02,560
place for launch

127
00:05:06,310 --> 00:05:03,600
in

128
00:05:08,150 --> 00:05:06,320
the spacex dragon there are several

129
00:05:11,189 --> 00:05:08,160
straps that they need to work together

130
00:05:12,870 --> 00:05:11,199
to remove it's very similar to the pma

131
00:05:15,430 --> 00:05:12,880
covers that we've been installing and

132
00:05:17,830 --> 00:05:15,440
removing in the past here you see kate

133
00:05:20,070 --> 00:05:17,840
working in the nbl to remove

134
00:05:21,110 --> 00:05:20,080
the straps from the handrails holding it

135
00:05:23,189 --> 00:05:21,120
in place

136
00:05:26,950 --> 00:05:23,199
the two of them need to work together to

137
00:05:29,430 --> 00:05:26,960
stuff that cover into the oru bag

138
00:05:33,350 --> 00:05:29,440
at that point they can install the two

139
00:05:35,110 --> 00:05:33,360
hemi reflectors onto the docking adapter

140
00:05:37,830 --> 00:05:35,120
and then the final thing that they need

141
00:05:40,950 --> 00:05:37,840
to do is made up the visiting vehicle

142
00:05:42,870 --> 00:05:40,960
power it's one final cable configuration

143
00:05:43,830 --> 00:05:42,880
that needs to be made

144
00:05:46,230 --> 00:05:43,840
jeff

145
00:05:48,629 --> 00:05:46,240
will complete that mating and at this

146
00:05:52,150 --> 00:05:48,639
point that docking adapter is ready to

147
00:05:53,990 --> 00:05:52,160
receive our new crew vehicles

148
00:05:55,990 --> 00:05:54,000
the crew can pack up and clean up this

149
00:05:59,430 --> 00:05:56,000
work site kate will pick up her foot

150
00:06:00,870 --> 00:05:59,440
restraint and return it to the esp2 from

151
00:06:04,230 --> 00:06:00,880
once it came

152
00:06:06,790 --> 00:06:04,240
jeff has to pack up the oru bag and also

153
00:06:09,110 --> 00:06:06,800
return his foot restraint

154
00:06:11,350 --> 00:06:09,120
his foot restraint goes back

155
00:06:13,749 --> 00:06:11,360
from where it's located where he's been

156
00:06:16,710 --> 00:06:13,759
using it on the pma he'll take it back

157
00:06:19,510 --> 00:06:16,720
up to the top of the columbus module

158
00:06:22,070 --> 00:06:19,520
it'll be staged there in place for the

159
00:06:25,430 --> 00:06:22,080
ida 3 installation that will be

160
00:06:27,350 --> 00:06:25,440
happening in late 2017.

161
00:06:30,390 --> 00:06:27,360
they return the oru bag back to the

162
00:06:33,270 --> 00:06:30,400
airlock and then go out kate will go out

163
00:06:36,950 --> 00:06:33,280
to the lab nader to a bag that's already

164
00:06:38,870 --> 00:06:36,960
there and route the cable for ida 3 we

165
00:06:40,870 --> 00:06:38,880
call it the white green cable because we

166
00:06:42,950 --> 00:06:40,880
put some tape marks on it in white and

167
00:06:45,590 --> 00:06:42,960
green to indicate which one it is she

168
00:06:47,749 --> 00:06:45,600
routes it forward to the node 2 where

169
00:06:49,350 --> 00:06:47,759
it's in position for the ida 3

170
00:06:51,749 --> 00:06:49,360
installation

171
00:06:55,990 --> 00:06:51,759
jeff has some work to do back

172
00:06:58,870 --> 00:06:56,000
in the area where the z1 the node 1 the

173
00:07:00,629 --> 00:06:58,880
node 3 and the lab all come together we

174
00:07:01,990 --> 00:07:00,639
refer to this area as the rats nest

175
00:07:03,270 --> 00:07:02,000
because of all of the cables and

176
00:07:06,629 --> 00:07:03,280
electrical

177
00:07:09,110 --> 00:07:06,639
route through that area

178
00:07:12,950 --> 00:07:09,120
he'll pick up the cable bundle that was

179
00:07:14,870 --> 00:07:12,960
left in position at the end of eva 35

180
00:07:17,749 --> 00:07:14,880
you'll make a couple of connections down

181
00:07:19,029 --> 00:07:17,759
on the node 2 and then route that cable

182
00:07:20,950 --> 00:07:19,039
across

183
00:07:23,670 --> 00:07:20,960
the z1 tray

184
00:07:25,589 --> 00:07:23,680
over to the starboard side of that tray

185
00:07:27,749 --> 00:07:25,599
and then leave it in position there

186
00:07:30,469 --> 00:07:27,759
where it will be ready for its final

187
00:07:33,350 --> 00:07:30,479
routing on a future eva the last

188
00:07:36,309 --> 00:07:33,360
scheduled task for this spacewalk will

189
00:07:38,070 --> 00:07:36,319
be to remove a couple of caps from some

190
00:07:39,909 --> 00:07:38,080
connectors that are located just

191
00:07:41,830 --> 00:07:39,919
underneath the z1

192
00:07:43,430 --> 00:07:41,840
on the outside of the

193
00:07:45,029 --> 00:07:43,440
node one

194
00:07:47,270 --> 00:07:45,039
at that point the crew will return to

195
00:07:49,510 --> 00:07:47,280
the airlock and ingress

196
00:07:51,110 --> 00:07:49,520
if we've been particularly

197
00:07:53,350 --> 00:07:51,120
lucky and efficient throughout the day

198
00:07:54,790 --> 00:07:53,360
and the hardware cooperates rather than

199
00:07:57,350 --> 00:07:54,800
ingressing the airlock we've got a

200
00:07:59,990 --> 00:07:57,360
couple of get ahead tasks that we can do

201
00:08:02,629 --> 00:08:00,000
one of them is to configure the port

202
00:08:04,950 --> 00:08:02,639
cedar cart we'll tie down the brake

203
00:08:07,670 --> 00:08:04,960
handles to keep them out of the way for

204
00:08:09,749 --> 00:08:07,680
long-term operations on station and then

205
00:08:12,710 --> 00:08:09,759
we also want to get some photos of the

206
00:08:14,469 --> 00:08:12,720
alpha magnetic spectrometer from the

207
00:08:16,790 --> 00:08:14,479
windows and from all the cameras on

208
00:08:19,430 --> 00:08:16,800
space station we cannot see the outboard

209
00:08:21,909 --> 00:08:19,440
side of the ams we'd like to get some

210
00:08:22,950 --> 00:08:21,919
photos of that area see how it's doing

211
00:08:24,710 --> 00:08:22,960
so

212
00:08:25,990 --> 00:08:24,720
they can get those photos from the top

213
00:08:27,909 --> 00:08:26,000
of the
