36
00:01:30,950 --> 00:01:28,320
begin assembling the upper triangle

37
00:01:32,870 --> 00:01:30,960
ev1 and ev2 will work together to build

38
00:01:35,030 --> 00:01:32,880
the upper triangle the crew will build

39
00:01:36,870 --> 00:01:35,040
the triangular segment loosely and that

40
00:01:38,550 --> 00:01:36,880
will tighten up the structure by driving

41
00:01:40,950 --> 00:01:38,560
the bolts to torque

42
00:01:42,950 --> 00:01:40,960
ev2 will then translate over to and

43
00:01:44,789 --> 00:01:42,960
ingress the foot restraint ev1 will

44
00:01:47,190 --> 00:01:44,799
reposition for the handoff maybe one

45
00:01:50,389 --> 00:01:47,200
will hand off the upper triangle to ev2

46
00:01:52,310 --> 00:01:50,399
ev2 will lay back and work to soft dock

47
00:01:55,350 --> 00:01:52,320
the segment onto the beta gimbal

48
00:01:57,670 --> 00:01:55,360
assembly and then drive four bolts ev1

49
00:02:00,870 --> 00:01:57,680
will temp stow her pgt with a short

50
00:02:03,030 --> 00:02:00,880
socket on a local handrail while ev2

51
00:02:05,749 --> 00:02:03,040
will egress the foot restraint and bias

52
00:02:08,550 --> 00:02:05,759
it to the left hand side ev1 will go

53
00:02:11,270 --> 00:02:08,560
over to the back and retrieve the left

54
00:02:15,510 --> 00:02:11,280
mid strut and work to pass this off to

55
00:02:18,150 --> 00:02:15,520
ev2 for a body restraint tetherstone ev2

56
00:02:20,790 --> 00:02:18,160
will then re-ingress the foot restraint

57
00:02:23,510 --> 00:02:20,800
while ev1 retrieves the long eight foot

58
00:02:26,949 --> 00:02:23,520
lower strut from the bag and hands it to

59
00:02:29,589 --> 00:02:26,959
ev2 while av2 holds the long lower strut

60
00:02:31,670 --> 00:02:29,599
ev1 will reposition to the solar array

61
00:02:34,150 --> 00:02:31,680
blanket box or saab

62
00:02:36,070 --> 00:02:34,160
for the install of the left lower strut

63
00:02:38,550 --> 00:02:36,080
as a team the crew will move the strut

64
00:02:41,990 --> 00:02:38,560
into position and ev1 will begin at

65
00:02:44,150 --> 00:02:42,000
driving this bolt by hand four turns ev2

66
00:02:46,309 --> 00:02:44,160
will then work to align and drive his

67
00:02:50,150 --> 00:02:46,319
bolt on the mounting bracket side two

68
00:02:52,070 --> 00:02:50,160
turns and then ev1 will work to complete

69
00:02:54,229 --> 00:02:52,080
the torque on this bolt by driving with

70
00:02:56,309 --> 00:02:54,239
the pistol grip tool to a high torque

71
00:02:57,910 --> 00:02:56,319
and then following with an even higher

72
00:03:00,630 --> 00:02:57,920
torque on the torque wrench once the

73
00:03:03,030 --> 00:03:00,640
bolt is deemed good ev2 will be given a

74
00:03:05,110 --> 00:03:03,040
go to drive his bolts to torque using

75
00:03:07,589 --> 00:03:05,120
the pistol grip tool and this completes

76
00:03:09,990 --> 00:03:07,599
our minimum config ev1 will reposition

77
00:03:11,830 --> 00:03:10,000
to the beta gimbal assembly and ev2 will

78
00:03:14,309 --> 00:03:11,840
hand off the telescoping mid strut for

79
00:03:17,190 --> 00:03:14,319
install ev1 will work to soft dock the

80
00:03:19,670 --> 00:03:17,200
side pad onto the bta while ev2 holds

81
00:03:22,070 --> 00:03:19,680
his clevis both side in place ev1 will

82
00:03:24,949 --> 00:03:22,080
start her four bolt two turns with the

83
00:03:26,550 --> 00:03:24,959
pistol grip tool and then ev2 will drive

84
00:03:29,030 --> 00:03:26,560
his clevis bolt to torque on the

85
00:03:32,070 --> 00:03:29,040
mounting bracket ev-1 will then complete

86
00:03:34,630 --> 00:03:32,080
her four bolts with her pistol grip tool

87
00:03:36,869 --> 00:03:34,640
and then ev2 will drive his bolt to

88
00:03:39,589 --> 00:03:36,879
torque

89
00:03:41,830 --> 00:03:39,599
ev2 will then egress and reposition the

90
00:03:43,190 --> 00:03:41,840
foot restraint to bias it to the right

91
00:03:44,949 --> 00:03:43,200
hand side

92
00:03:47,270 --> 00:03:44,959
the mod the crew will then repeat the

93
00:03:49,910 --> 00:03:47,280
handoff sequence first then mid strut

94
00:03:52,309 --> 00:03:49,920

96
00:03:57,110 --> 00:03:55,200
of the very long lower right strut ev1

97
00:03:59,030 --> 00:03:57,120
will then reposition to the right hand

98
00:04:01,670 --> 00:03:59,040
side of the three alpha beta gimbal

99
00:04:04,470 --> 00:04:01,680
assembly and an analogous install on

100
00:04:07,030 --> 00:04:04,480

103
00:04:14,949 --> 00:04:12,959
to torque ev1 will drive his clevis

104
00:04:17,509 --> 00:04:14,959
bolts to the mounting bracket

105
00:04:18,710 --> 00:04:17,519
ev-1 will then reposition at the bga and

106
00:04:20,629 --> 00:04:18,720
they will hand off the wright's

107
00:04:22,550 --> 00:04:20,639
telescoping mid-struts following the

108
00:04:24,550 --> 00:04:22,560
same install strategy

109
00:04:26,710 --> 00:04:24,560
once complete tv-1 will translate onto

110
00:04:28,710 --> 00:04:26,720
the mid-strut and drive two collar bolts

111
00:04:30,469 --> 00:04:28,720
to torque to lock out the telescoping

112
00:04:32,390 --> 00:04:30,479
mechanism and rigidize the right hand

113
00:04:35,670 --> 00:04:32,400

129
00:05:11,909 --> 00:05:10,080
over to the non-radiator side of the iea

130
00:05:13,990 --> 00:05:11,919
to take some still imagery of the

131
00:05:16,550 --> 00:05:14,000
completed mod kit ev1 will then

132
00:05:18,870 --> 00:05:16,560
translate out to s6 to our battery

133
00:05:21,350 --> 00:05:18,880

148
00:05:57,430 --> 00:05:55,280
allow for robotic access when needed in

149
00:05:59,830 --> 00:05:57,440
the future they'll perform some on-orbit

150
00:06:02,469 --> 00:05:59,840
origami record it to the shape of a

151
00:06:04,629 --> 00:06:02,479
triangle and restrain it out with a wire

152
00:06:07,909 --> 00:06:04,639
tie to a local handrail the crew will

153
00:06:10,150 --> 00:06:07,919
then work to break torque first on h1

154
00:06:13,029 --> 00:06:10,160
followed by h2 and then restrain the

155
00:06:15,830 --> 00:06:13,039
