the truss and goes starboard he stops to

restraint bolt on the upper eye Rosa

00:01:02,209 --> 00:01:00,600
ev2 relocates the foot restraint and

26
00:01:03,650 --> 00:01:02,219
installs it on the Space Station's

28
00:01:08,690 --> 00:01:06,840
ev2 ingresses the foot restraint and

29
00:01:10,670 --> 00:01:08,700
then the arm will move them away from

releases its first restraint bulb he

33
00:01:20,990 --> 00:01:18,720
releases both anti-rotation devices back

34
00:01:22,860 --> 00:01:21,000
on the upper eye Rosa and then we'll

access two sets of bolts on the boom end

39
00:01:42,590 --> 00:01:40,079
of the upper irosa

40
00:01:44,990 --> 00:01:42,600
the first two bolts will allow the boom

deployment system rollers to be moved

42
00:01:51,490 --> 00:01:46,680
into place to help with the array

43
00:01:57,230 --> 00:01:54,830
the second two bolts will release two of

of the upper eye Rosa and both crew

53
00:02:20,630 --> 00:02:17,700
members work to release the final bolt

54
00:02:23,390 --> 00:02:20,640
holding it to the carrier eb1 installs a

work site during these Maneuvers ev1

60
00:02:46,729 --> 00:02:44,280
will pick up the temporarily stowed bag

61
00:02:49,309 --> 00:02:46,739
from the port cart and reconfigure both

67
00:03:14,570 --> 00:03:12,659
the crew will release the scoops and ev2

68
00:03:16,790 --> 00:03:14,580
will move into position to release the

69
00:03:17,890 --> 00:03:16,800
final bolt holding iroza in its folded

70
00:03:20,809 --> 00:03:17,900
position

71
00:03:23,030 --> 00:03:20,819
once released ev1 will hold our Rosa

72
00:03:26,030 --> 00:03:23,040
closed while ev2 egresses his foot

73
00:03:27,890 --> 00:03:26,040
restraint and gets into position

74
00:03:29,930 --> 00:03:27,900
both crew will then work together to

75
00:03:32,210 --> 00:03:29,940
unfold iroza and secure the right side

76
00:03:35,630 --> 00:03:32,220
onto the mounting bracket

77
00:03:37,550 --> 00:03:35,640
once secured ev2 will drive two hinge

78
00:03:39,110 --> 00:03:37,560
bolts that hold iroza in the unfolded

79
00:03:42,170 --> 00:03:39,120
position

80
00:03:44,449 --> 00:03:42,180
ev2 will then move away from my Rosa to

81
00:03:47,509 --> 00:03:44,459
reconfigure her safety tether on the arm

82
00:03:54,190 --> 00:03:47,519
ev1 Works to drive 8 bolts to fully

83
00:03:59,330 --> 00:03:57,229
both crew will then work to electrically

84
00:04:01,970 --> 00:03:59,340
connect the new iroza to the ISS power

85
00:04:04,670 --> 00:04:01,980
system they'll first attach four

86
00:04:07,009 --> 00:04:04,680
connectors to a Rosa then both will move

87
00:04:09,350 --> 00:04:07,019
to either side of the Legacy array to

88
00:04:11,449 --> 00:04:09,360
disconnect the old array and connect a

89
00:04:13,670 --> 00:04:11,459
white cable this will allow power to

90
00:04:15,830 --> 00:04:13,680
flow from both the new irosa and the

91
00:04:16,259 --> 00:04:15,840
Legacy array to the space station power

92
00:04:24,249 --> 00:04:16,269
system

93
00:04:29,450 --> 00:04:27,110
at this point ev1 moves into a

94
00:04:31,490 --> 00:04:29,460
deployment viewing position and ev2 will

95
00:04:33,790 --> 00:04:31,500
release the final two bolts restraining

96
00:04:36,710 --> 00:04:33,800
irosa in the undeployed position

97
00:04:37,850 --> 00:04:36,720
iroza will deploy over the next 6 to 10

98
00:04:40,969 --> 00:04:37,860
minutes

99
00:04:43,249 --> 00:04:40,979
during deployment ev1 translates back to

100
00:04:44,990 --> 00:04:43,259
diversa carrier to reconfigure the

101
00:04:45,990 --> 00:04:45,000
carrier beams that previously held the

102
00:04:47,450 --> 00:04:46,000
upper irosa

00:04:49,730 --> 00:04:47,460
[Music]

104
00:04:52,010 --> 00:04:49,740
these beams need to be rotated out of

105
00:04:56,390 --> 00:04:52,020
the way to allow access to the lower

106
00:05:01,129 --> 00:04:59,270
once deployment is complete ev2 will

107
00:05:03,530 --> 00:05:01,139
release two bolts that allow the erosa

108
00:05:06,370 --> 00:05:03,540
blankets to become tensioned

109
00:05:09,409 --> 00:05:06,380
ev2 then cleans up the mod kit worksite

110
00:05:11,450 --> 00:05:09,419
retrieving his crew lock bag and head to

111
00:05:15,530 --> 00:05:11,460
the carrier to help ev1 with the carrier

112
00:05:19,070 --> 00:05:17,330
the crew members work together to

113
00:05:19,790 --> 00:05:19,080
release the bolts holding the beams in

114
00:05:21,770 --> 00:05:19,800
place

115
00:05:25,610 --> 00:05:21,780
then they will rotate the beams out of

116
00:05:28,550 --> 00:05:25,620
the way and secure them back down

117
00:05:36,129 --> 00:05:28,560
this is the last task in the first Eva

118
00:05:41,450 --> 00:05:38,570
both crew will clean up the work site

119
00:05:44,150 --> 00:05:41,460
and translate back to the airlock they

120
00:05:46,850 --> 00:05:44,160
will clean up their tethers on the way

121
00:05:49,850 --> 00:05:46,860
they will then work to Ingress and begin

122
00:05:55,030 --> 00:05:49,860
repressing the airlock this will finish
