1
00:00:16,550 --> 00:00:14,709
good day and welcome to mission control

2
00:00:18,630 --> 00:00:16,560
houston where the international space

3
00:00:20,470 --> 00:00:18,640
station flight control team is watching

4
00:00:21,429 --> 00:00:20,480
over the systems aboard the orbiting

5
00:00:23,990 --> 00:00:21,439
outpost

6
00:00:25,029 --> 00:00:24,000
as it tracks across the atlantic ocean

7
00:00:27,269 --> 00:00:25,039
from

8
00:00:29,990 --> 00:00:27,279
northwest to southeast

9
00:00:32,470 --> 00:00:30,000
at an altitude about 250 statute miles

10
00:00:34,790 --> 00:00:32,480
on board the expedition 36 crew

11
00:00:36,950 --> 00:00:34,800
commander pavel vinogradov and

12
00:00:39,270 --> 00:00:36,960
flight engineers alexander misurkin

13
00:00:42,709 --> 00:00:39,280
chris cassidy fyodor yoshikin luca

14
00:00:45,030 --> 00:00:42,719
parmitano and karen nyberg are all

15
00:00:46,549 --> 00:00:45,040
busy with another day of on-orbit

16
00:00:49,110 --> 00:00:46,559
operations

17
00:00:51,190 --> 00:00:49,120
following yesterday's shortened one-hour

18
00:00:52,389 --> 00:00:51,200
32-minute spacewalk

19
00:00:55,189 --> 00:00:52,399
the team

20
00:00:58,150 --> 00:00:55,199
in the u.s side of the space station in

21
00:01:00,470 --> 00:00:58,160
particular spacewalkers chris cassidy of

22
00:01:02,150 --> 00:01:00,480
nasa and luca pomotano of the european

23
00:01:04,390 --> 00:01:02,160
space agency

24
00:01:06,950 --> 00:01:04,400
have been conducting exhaustive

25
00:01:08,710 --> 00:01:06,960
troubleshooting activities taking a look

26
00:01:11,270 --> 00:01:08,720
at the spacesuit that was worn by luca

27
00:01:13,190 --> 00:01:11,280
parmitano on that one hour and 32

28
00:01:15,270 --> 00:01:13,200
minutes spacewalk

29
00:01:17,270 --> 00:01:15,280
shortly after he

30
00:01:18,950 --> 00:01:17,280
completed his first task of the

31
00:01:20,710 --> 00:01:18,960
spacewalk which is scheduled to be six

32
00:01:23,030 --> 00:01:20,720
and a half hours long

33
00:01:25,510 --> 00:01:23,040
he reported some water

34
00:01:27,990 --> 00:01:25,520
inside his helmet

35
00:01:30,469 --> 00:01:28,000
i didn't think it was immediately going

36
00:01:32,469 --> 00:01:30,479
to be an issue but after his fellow

37
00:01:34,230 --> 00:01:32,479
spacewalker chris cassidy was able to

38
00:01:35,590 --> 00:01:34,240
get a look inside

39
00:01:37,590 --> 00:01:35,600
his

40
00:01:40,550 --> 00:01:37,600
face plate he saw that there was more

41
00:01:42,630 --> 00:01:40,560
water than they believed there was and

42
00:01:46,149 --> 00:01:42,640
worked with the flight control team

43
00:01:48,230 --> 00:01:46,159
flight director dave korth and

44
00:01:50,230 --> 00:01:48,240
karina eversley the lead

45
00:01:52,389 --> 00:01:50,240
spacewalk officer and made a quick

46
00:01:54,389 --> 00:01:52,399
determination that it was a potential

47
00:01:56,469 --> 00:01:54,399
hazard and that they needed to terminate

48
00:01:58,230 --> 00:01:56,479
the spacewalk ended early and bring the

49
00:01:59,990 --> 00:01:58,240
crew back inside to make sure that they

50
00:02:01,030 --> 00:02:00,000
were safe

51
00:02:02,789 --> 00:02:01,040
all that

52
00:02:05,350 --> 00:02:02,799
went very well the

53
00:02:07,429 --> 00:02:05,360
team here has trained for a

54
00:02:09,029 --> 00:02:07,439
contingency reentry into the quest

55
00:02:11,190 --> 00:02:09,039
airlock module which you're looking at

56
00:02:12,630 --> 00:02:11,200
here in some video from yesterday's

57
00:02:14,790 --> 00:02:12,640
spacewalk

58
00:02:16,790 --> 00:02:14,800
and they were able to successfully get

59
00:02:18,869 --> 00:02:16,800
parmitano and cassidy quickly back into

60
00:02:20,949 --> 00:02:18,879
the airlock and then back into the

61
00:02:23,190 --> 00:02:20,959
international space station

62
00:02:26,229 --> 00:02:23,200
where they were able to get promitano

63
00:02:29,030 --> 00:02:26,239
and cassidy out of their suits and

64
00:02:31,510 --> 00:02:29,040
make sure that everybody was okay

65
00:02:33,350 --> 00:02:31,520
today the work has been focusing on

66
00:02:35,270 --> 00:02:33,360
trying to troubleshoot

67
00:02:36,550 --> 00:02:35,280
what might have gone wrong there still

68
00:02:38,869 --> 00:02:36,560
is no

69
00:02:41,190 --> 00:02:38,879
smoking gun or definite cause of what

70
00:02:43,910 --> 00:02:41,200
happened or why that water

71
00:02:45,509 --> 00:02:43,920
ended up inside parmitano's spacesuit

72
00:02:48,309 --> 00:02:45,519
there are a couple of different

73
00:02:49,110 --> 00:02:48,319
potential sources for that water

74
00:02:54,869 --> 00:02:49,120
the

75
00:02:57,509 --> 00:02:54,879
hydrated with

76
00:03:00,710 --> 00:02:57,519
uh there also is water that courses

77
00:03:02,550 --> 00:03:00,720
through a set of tubing in their

78
00:03:05,990 --> 00:03:02,560
essentially long underwear that's used

79
00:03:07,830 --> 00:03:06,000
to cool them when they are outside the

80
00:03:09,750 --> 00:03:07,840
space station

81
00:03:11,270 --> 00:03:09,760
and that water flows through a different

82
00:03:13,670 --> 00:03:11,280
sets of plumbing

83
00:03:16,229 --> 00:03:13,680
both inside the the suit around the

84
00:03:18,309 --> 00:03:16,239
astronauts and in the backpack

85
00:03:20,470 --> 00:03:18,319
the team here on the ground today has

86
00:03:21,910 --> 00:03:20,480
been doing a variety of different

87
00:03:23,589 --> 00:03:21,920
troubleshooting activities some of these

88
00:03:25,670 --> 00:03:23,599
we're seeing from recorded video

89
00:03:27,430 --> 00:03:25,680
downlinked here in the

90
00:03:29,670 --> 00:03:27,440
equipment lock portion of the quest

91
00:03:32,229 --> 00:03:29,680
airlock module

92
00:03:35,030 --> 00:03:32,239
activating the equipment lock beginning

93
00:03:37,190 --> 00:03:35,040
to recharge the suit with water

94
00:03:39,350 --> 00:03:37,200
inspecting every nook and cranny for any

95
00:03:41,509 --> 00:03:39,360
signs of water leakage

96
00:03:43,830 --> 00:03:41,519
so far there hasn't been any immediate

97
00:03:46,550 --> 00:03:43,840
noticeable leakage other some droplets

98
00:03:49,030 --> 00:03:46,560
in the neighborhood of of one of the

99
00:03:50,869 --> 00:03:49,040
inlet loops from the canisters you used

100
00:03:52,630 --> 00:03:50,879
to scrub that because carbon dioxide

101
00:03:54,229 --> 00:03:52,640
from the spacesuits

102
00:03:55,750 --> 00:03:54,239
but the spacewalk specialists here in

103
00:03:58,470 --> 00:03:55,760
mission control

104
00:04:01,350 --> 00:03:58,480
have seen a higher than usual usage of

105
00:04:03,750 --> 00:04:01,360
water from the feed tank that runs

106
00:04:05,030 --> 00:04:03,760
throughout the system and the suits

107
00:04:06,949 --> 00:04:05,040
plumbing

108
00:04:08,630 --> 00:04:06,959
and that could have been consistent with

109
00:04:11,030 --> 00:04:08,640
the readings that were seen yesterday

110
00:04:12,390 --> 00:04:11,040
when promatano's helmet began to fill up

111
00:04:15,670 --> 00:04:12,400
with water

112
00:04:18,150 --> 00:04:15,680
again no real theory yet on exactly

113
00:04:19,909 --> 00:04:18,160
where this water came from or why but

114
00:04:23,030 --> 00:04:19,919
they're doing a

115
00:04:25,590 --> 00:04:23,040
very uh deliberate step-by-step process

116
00:04:29,350 --> 00:04:25,600
of troubleshooting to try and identify

117
00:04:32,469 --> 00:04:29,360
uh what's going on uh the spacesuits are

118
00:04:34,870 --> 00:04:32,479
in a way a combination of of parts uh

119
00:04:36,710 --> 00:04:34,880
and uh there is uh there's an additional

120
00:04:39,350 --> 00:04:36,720
spacesuit onboard the space station

121
00:04:41,909 --> 00:04:39,360
should there be any uh contingency

122
00:04:44,230 --> 00:04:41,919
outside that would be

123
00:04:45,670 --> 00:04:44,240
necessary to have a spacewalk something

124
00:04:47,189 --> 00:04:45,680
that would be very important to the

125
00:04:49,670 --> 00:04:47,199
space station

126
00:04:52,310 --> 00:04:49,680
they could resize spacesuits and have

127
00:04:54,390 --> 00:04:52,320
these guys ready to go out uh assuming

128
00:04:55,990 --> 00:04:54,400
that they're able to identify that this

129
00:04:57,350 --> 00:04:56,000
is not a uh

130
00:04:59,590 --> 00:04:57,360
any kind of an issue that will affect

131
00:05:01,350 --> 00:04:59,600
all space suits uh and that they're able

132
00:05:04,629 --> 00:05:01,360
to isolate it to this particular suit

133
00:05:06,310 --> 00:05:04,639
that parmitano was wearing uh

134
00:05:07,909 --> 00:05:06,320
chris cassidy didn't have any problems

135
00:05:10,870 --> 00:05:07,919
with his suit yesterday so there's no

136
00:05:12,870 --> 00:05:10,880
evidence that there is a generic problem

137
00:05:14,469 --> 00:05:12,880
with the spacesuits and so

138
00:05:16,150 --> 00:05:14,479
the team now is focusing on trying to

139
00:05:19,110 --> 00:05:16,160
figure out exactly what

140
00:05:22,629 --> 00:05:19,120
happened yesterday so that they can

141
00:05:25,270 --> 00:05:22,639
identify and design a repair procedure

142
00:05:27,749 --> 00:05:25,280
or shift over to alternate spacesuits

143
00:05:29,749 --> 00:05:27,759
and no plan as of yet and as to when

144
00:05:31,430 --> 00:05:29,759
they might try to do any of those tasks

145
00:05:33,110 --> 00:05:31,440
that were unable to be accomplished on

146
00:05:35,189 --> 00:05:33,120
yesterday's spacewalk

147
00:05:36,710 --> 00:05:35,199
none of those tasks was particularly

148
00:05:38,150 --> 00:05:36,720
time critical

149
00:05:41,189 --> 00:05:38,160
and so the team here is going to take a

150
00:05:43,110 --> 00:05:41,199
very deliberate and uh careful uh look

151
00:05:45,110 --> 00:05:43,120
at everything

152
00:05:47,189 --> 00:05:45,120
of course uh research continuing aboard

153
00:05:49,029 --> 00:05:47,199
the international space station today uh

154
00:05:52,150 --> 00:05:49,039
russians working with a variety of

155
00:05:54,230 --> 00:05:52,160
different experiments uh karen nyberg

156
00:05:56,550 --> 00:05:54,240
also doing some proficiency training for

157
00:05:57,510 --> 00:05:56,560
her role as the crew medical officer on

158
00:05:59,270 --> 00:05:57,520
board

159
00:06:01,270 --> 00:05:59,280
she's also scheduled to be replacing a

160
00:06:02,950 --> 00:06:01,280
recycling system tank in the

161
00:06:05,430 --> 00:06:02,960
environmental control life support

162
00:06:08,950 --> 00:06:05,440
system and working with the advanced

163
00:06:11,830 --> 00:06:08,960
biological research system

164
00:06:14,070 --> 00:06:11,840
the space walkers also are uh stowing

165
00:06:16,390 --> 00:06:14,080
the tools that they had pulled out for

166
00:06:17,670 --> 00:06:16,400
yesterday's eva so that they are out of

167
00:06:18,790 --> 00:06:17,680
the way

168
00:06:20,550 --> 00:06:18,800
and not

169
00:06:25,430 --> 00:06:20,560
any impediment to the troubleshooting

170
00:06:30,309 --> 00:06:27,590
a lot of research has been going on

171
00:06:33,270 --> 00:06:30,319
throughout the week of this

172
00:06:36,390 --> 00:06:33,280
expedition 36 activity

173
00:06:38,870 --> 00:06:36,400
in addition to that they've been

174
00:06:41,590 --> 00:06:38,880
performing a large number almost a full

175
00:06:43,830 --> 00:06:41,600
uh work week's worth of

176
00:06:45,270 --> 00:06:43,840
research going on

177
00:06:46,550 --> 00:06:45,280
last week

178
00:06:49,590 --> 00:06:46,560
about

179
00:06:51,590 --> 00:06:49,600
17 hours worth of crew time was uh

180
00:06:53,670 --> 00:06:51,600
scheduled for research even though the

181
00:06:56,790 --> 00:06:53,680
uh we had the spacewalk and all those

182
00:06:59,990 --> 00:06:56,800
preparations going on and also uh the

183
00:07:03,110 --> 00:07:00,000
crew uh on the russian uh portion of the

184
00:07:05,110 --> 00:07:03,120
station has been busy uh packing up

185
00:07:07,589 --> 00:07:05,120
trash and no longer needed items inside

186
00:07:09,270 --> 00:07:07,599
the progress 50 spacecraft which is

187
00:07:13,189 --> 00:07:09,280
scheduled to undock from the

188
00:07:14,950 --> 00:07:13,199
international space station on july 25

189
00:07:18,469 --> 00:07:14,960
the coverage of that on nasa tv will

190
00:07:22,070 --> 00:07:18,479
begin at 3 30 pm central time and the

191
00:07:25,350 --> 00:07:22,080
