1
00:00:04,789 --> 00:00:02,869
for eva 40 as was mentioned shane is

2
00:00:06,150 --> 00:00:04,799
going to be ev1 and tomorrow's going to

3
00:00:07,590 --> 00:00:06,160
be ev2

4
00:00:09,669 --> 00:00:07,600
they are going to be swapping roles

5
00:00:12,470 --> 00:00:09,679
coming out the door so to give tomas

6
00:00:14,150 --> 00:00:12,480
some experience of opening up that hatch

7
00:00:15,910 --> 00:00:14,160
it's and the crew members are going to

8
00:00:17,910 --> 00:00:15,920
be separated throughout the entire eva

9
00:00:19,189 --> 00:00:17,920
so first we'll go through what shane is

10
00:00:21,109 --> 00:00:19,199
going to be doing

11
00:00:23,429 --> 00:00:21,119
his first task he's going to be heading

12
00:00:25,269 --> 00:00:23,439
over to to s0 where he's going to be

13
00:00:26,470 --> 00:00:25,279
changing out that computer processor

14
00:00:28,230 --> 00:00:26,480
that

15
00:00:29,429 --> 00:00:28,240
emily was mentioning so there's

16
00:00:30,870 --> 00:00:29,439
currently not anything wrong with that

17
00:00:32,150 --> 00:00:30,880
processor we are just going to be

18
00:00:35,270 --> 00:00:32,160
upgrading it

19
00:00:37,750 --> 00:00:35,280
and making it more enhanced

20
00:00:39,910 --> 00:00:37,760
so you see here he's going to be

21
00:00:42,389 --> 00:00:39,920
changing out that box

22
00:00:44,310 --> 00:00:42,399
and installing the new one

23
00:00:45,750 --> 00:00:44,320
technical terms for that we call it the

24
00:00:47,270 --> 00:00:45,760
the epic

25
00:00:49,750 --> 00:00:47,280
mdm

26
00:00:51,830 --> 00:00:49,760
and so once he installs that box into

27
00:00:53,430 --> 00:00:51,840
the slot he does have some a cable to

28
00:00:55,350 --> 00:00:53,440
connect up to that that's going to give

29
00:00:57,430 --> 00:00:55,360
it that that ethernet connection which

30
00:00:59,270 --> 00:00:57,440
is that enhanced capability

31
00:01:02,389 --> 00:00:59,280
once he's complete with that he heads on

32
00:01:04,950 --> 00:01:02,399
over to pma3 where he is going to be

33
00:01:07,590 --> 00:01:04,960
disconnecting certain umbilicals to

34
00:01:11,109 --> 00:01:07,600
allow that vehicle or that module to be

35
00:01:12,950 --> 00:01:11,119
relocated in between eva 40 and 41.

36
00:01:15,190 --> 00:01:12,960
so there are four different

37
00:01:17,190 --> 00:01:15,200
disconnects that he needs to do

38
00:01:18,390 --> 00:01:17,200
once it's disconnected he's going to go

39
00:01:20,310 --> 00:01:18,400
ahead and

40
00:01:22,789 --> 00:01:20,320
make sure that they're out of the way

41
00:01:24,710 --> 00:01:22,799
and tie those down for this segment to

42
00:01:26,390 --> 00:01:24,720
be relocated

43
00:01:28,630 --> 00:01:26,400
after that he's going to head on out to

44
00:01:30,870 --> 00:01:28,640
the the japanese module

45
00:01:32,710 --> 00:01:30,880
where he has the two cameras that he's

46
00:01:34,149 --> 00:01:32,720
going to be changing out as emily

47
00:01:36,069 --> 00:01:34,159
mentioned the cameras do have some

48
00:01:37,510 --> 00:01:36,079
lights burned down on them and in order

49
00:01:38,870 --> 00:01:37,520
to change those you need to just change

50
00:01:41,510 --> 00:01:38,880
out the box and change out the light

51
00:01:43,830 --> 00:01:41,520
bulb inside so the first one is on the

52
00:01:46,550 --> 00:01:43,840
the japanese robotic arm so he's going

53
00:01:47,990 --> 00:01:46,560
to change that one out first

54
00:01:49,429 --> 00:01:48,000
and then you'll see him

55
00:01:51,910 --> 00:01:49,439
he's going to translate on the nader

56
00:01:53,910 --> 00:01:51,920
side of this palette to head on over to

57
00:01:55,270 --> 00:01:53,920
the the work site of the other camera

58
00:01:57,830 --> 00:01:55,280
which is going to be on the forward side

59
00:01:58,870 --> 00:01:57,840
of this palette and and change out that

60
00:02:00,469 --> 00:01:58,880
one

61
00:02:02,149 --> 00:02:00,479
it's great he's got a big bag where he

62
00:02:04,149 --> 00:02:02,159
can put both of those cameras in so we

63
00:02:06,069 --> 00:02:04,159
we save a lot of time by not needing to

64
00:02:08,550 --> 00:02:06,079
go back and forth to the airlock to get

65
00:02:10,949 --> 00:02:08,560
each particular camera so once he's

66
00:02:13,350 --> 00:02:10,959
complete with with this camera r r that

67
00:02:15,670 --> 00:02:13,360
is the that's all of his planned tasks

68
00:02:17,670 --> 00:02:15,680
that he has for the eva we hope to do

69
00:02:20,070 --> 00:02:17,680
have some time for some get-aheads but

70
00:02:21,589 --> 00:02:20,080
we'll assess that the day of

71
00:02:22,869 --> 00:02:21,599
then moving on to what tamar's going to

72
00:02:25,190 --> 00:02:22,879
be doing

73
00:02:27,670 --> 00:02:25,200
first he heads on out to esp2 where he's

74
00:02:29,589 --> 00:02:27,680
going to be grabbing a foot restraint

75
00:02:31,589 --> 00:02:29,599
and also he's going to be grabbing an

76
00:02:33,830 --> 00:02:31,599
extender for that foot restraint both of

77
00:02:35,990 --> 00:02:33,840
the tasks that he's doing do require a

78
00:02:37,509 --> 00:02:36,000
little bit more reach

79
00:02:38,390 --> 00:02:37,519
in that foot restraint so he's going to

80
00:02:41,670 --> 00:02:38,400
take

81
00:02:43,350 --> 00:02:41,680
both of those pieces over to p1 where he

82
00:02:45,910 --> 00:02:43,360
is going to be

83
00:02:47,030 --> 00:02:45,920
inspecting the ammonia leaks that emily

84
00:02:47,910 --> 00:02:47,040
had mentioned

85
00:02:50,630 --> 00:02:47,920
so

86
00:02:52,949 --> 00:02:50,640
there if this is an rbvm a radiator

87
00:02:54,070 --> 00:02:52,959
valve beam module um

88
00:02:56,150 --> 00:02:54,080
and

89
00:02:58,229 --> 00:02:56,160
it's in the flow path of the ammonia of

90
00:03:00,070 --> 00:02:58,239
the cooling system and so he's just

91
00:03:01,910 --> 00:03:00,080
going to be checking that hardware out

92
00:03:03,910 --> 00:03:01,920
seeing if there's if there's any

93
00:03:05,750 --> 00:03:03,920
indication of leaks this is a close-up

94
00:03:08,070 --> 00:03:05,760
of that hardware so using me checking

95
00:03:10,309 --> 00:03:08,080
these flex hoses we also have fluid

96
00:03:11,750 --> 00:03:10,319
quick disconnects as well as rigid

97
00:03:13,830 --> 00:03:11,760
systems lines

98
00:03:15,110 --> 00:03:13,840
all that again we'll just need the human

99
00:03:17,030 --> 00:03:15,120
eyes on it to see if there's any

100
00:03:19,509 --> 00:03:17,040
indication of a leak and it would be the

101
00:03:21,990 --> 00:03:19,519
ammonia coming out of there

102
00:03:24,789 --> 00:03:22,000
once he's complete with that inspection

103
00:03:27,110 --> 00:03:24,799
he heads on out to s0 where he's going

104
00:03:31,270 --> 00:03:27,120
to be lubricating the

105
00:03:33,430 --> 00:03:31,280
robotic manipulator the spdm

106
00:03:35,589 --> 00:03:33,440
it's a spdm lee

107
00:03:37,670 --> 00:03:35,599
we have lubricated other parts of the

108
00:03:39,750 --> 00:03:37,680
the space station robotic arm on

109
00:03:41,750 --> 00:03:39,760
previous evas and

110
00:03:44,149 --> 00:03:41,760
this robotic manipulator has been

111
00:03:45,430 --> 00:03:44,159
showing similar signs of degradation so

112
00:03:47,750 --> 00:03:45,440
what we're going to do

113
00:03:50,070 --> 00:03:47,760
is we have a specialized tool for it

114
00:03:51,750 --> 00:03:50,080
it's called the blt

115
00:03:54,070 --> 00:03:51,760
not a bacon lettuce and tomato it's a

116
00:03:55,509 --> 00:03:54,080
ball screw lubrication tool

117
00:03:57,509 --> 00:03:55,519
so what you do is you you're going to be

118
00:03:59,429 --> 00:03:57,519
applying grease to this cradle so you're

119
00:04:01,270 --> 00:03:59,439
going to be inserting it into the cavity

120
00:04:03,110 --> 00:04:01,280
here there's a there's a ball screw that

121
00:04:05,589 --> 00:04:03,120
we need to get the grease on and then

122
00:04:07,509 --> 00:04:05,599
each of these four latches also have a

123
00:04:09,589 --> 00:04:07,519
similar ball screw that you need this

124
00:04:10,789 --> 00:04:09,599
tool to insert to to access those ball

125
00:04:12,869 --> 00:04:10,799
screws

126
00:04:15,589 --> 00:04:12,879
the last part of the lubrication there's

127
00:04:17,270 --> 00:04:15,599
some tracks on each of the latches here

128
00:04:17,990 --> 00:04:17,280
that also need to get grease applied to

129
00:04:19,830 --> 00:04:18,000
them

130
00:04:21,349 --> 00:04:19,840
that we're just going to be using a

131
00:04:23,110 --> 00:04:21,359
standard grease gun which kind of looks

132
00:04:24,790 --> 00:04:23,120
more like a caulking gun

133
00:04:26,710 --> 00:04:24,800
off the shelf caulking gun that's got

134
00:04:27,749 --> 00:04:26,720
grease in it this is just showing the

135
00:04:31,350 --> 00:04:27,759
grease

136
00:04:33,350 --> 00:04:31,360
being applied to the cradle of this tool

137
00:04:34,950 --> 00:04:33,360
this is going inside one of the latches

138
00:04:37,510 --> 00:04:34,960
this is what that ball screw looks like

139
00:04:39,110 --> 00:04:37,520
inside the latch with the grease applied

140
00:04:41,189 --> 00:04:39,120
to it

141
00:04:42,469 --> 00:04:41,199
and so once once he's complete with that

142
00:04:45,189 --> 00:04:42,479
the lubrication

143
00:04:47,110 --> 00:04:45,199
um he's done with his planned task and

144
00:04:49,350 --> 00:04:47,120
both crew members would be heading back

145
00:04:51,670 --> 00:04:49,360
to the airlock again if we've got time

146
00:04:53,030 --> 00:04:51,680
um for other activities we've got some

147
00:04:57,590 --> 00:04:53,040
time at the end of the eva we'll assess

148
00:05:00,210 --> 00:04:57,600
that day of for any get-ahead activities
