1
00:00:00,650 --> 00:00:05,160
Luca parmitano Andrew Morgan will once

2
00:00:03,300 --> 00:00:06,810
again be going out on a Messi VA this

3
00:00:05,160 --> 00:00:09,780
will be e VA number three in the repair

4
00:00:06,810 --> 00:00:11,190
sequence this is the VA with a new AMS

5
00:00:09,780 --> 00:00:15,809
pump system will be brought out of the

6
00:00:11,190 --> 00:00:18,000
airlock and installed on AMS itself the

7
00:00:15,809 --> 00:00:19,260
pump system is rather large and cannot

8
00:00:18,000 --> 00:00:20,820
be transported by a single crew member

9
00:00:19,260 --> 00:00:22,920
therefore both crew work together

10
00:00:20,820 --> 00:00:24,570
handing off the pump system one to the

11
00:00:22,920 --> 00:00:26,099
other as they inch worm their way from

12
00:00:24,570 --> 00:00:27,750
the airlock all the way to the forward

13
00:00:26,099 --> 00:00:30,380
side of the external support platform

14
00:00:27,750 --> 00:00:30,380
number two

15
00:00:31,670 --> 00:00:36,960
the canadarm2 or SSRMS will meet the

16
00:00:34,710 --> 00:00:38,520
crew there at what point drew will take

17
00:00:36,960 --> 00:00:40,380
control of the pump system while Luca

18
00:00:38,520 --> 00:00:43,640
ingresses the articulating portable foot

19
00:00:40,380 --> 00:00:43,640
restraint on the SSRMS

20
00:00:45,250 --> 00:00:49,719
once in the photo strange Luca will take

21
00:00:47,469 --> 00:00:52,420
the pump system and prepare for the

22
00:00:49,719 --> 00:00:55,449
flight of the canadarm2 from ESP to all

23
00:00:52,420 --> 00:00:56,829
the way over top of the trust AMS in a

24
00:00:55,449 --> 00:01:08,110
similar manage of the trajectories he's

25
00:00:56,829 --> 00:01:10,270
taken on EVs 1 & 2 well he's riding the

26
00:01:08,110 --> 00:01:12,070
Canada arm to drill we'll translate and

27
00:01:10,270 --> 00:01:15,159
of her hand across the truss and up to

28
00:01:12,070 --> 00:01:16,840
ELC - with bags to prepare the work site

29
00:01:15,159 --> 00:01:23,619
to meet Luca therefore the installation

30
00:01:16,840 --> 00:01:25,960
of the pump system drew will provide

31
00:01:23,619 --> 00:01:28,630
eyes on to assist Luca and aligning the

32
00:01:25,960 --> 00:01:31,710
system and install it on to AMS into the

33
00:01:28,630 --> 00:01:31,710
mechanical attachment device

34
00:01:32,500 --> 00:01:37,510
once there the crew will use the pistol

35
00:01:35,020 --> 00:01:39,220
grip tool to PGT to connect the bolts as

36
00:01:37,510 --> 00:01:42,280
well as connecting the power and data

37
00:01:39,220 --> 00:01:44,380
cables securing the new pump system to

38
00:01:42,280 --> 00:01:46,770
AMS and allowing the heaters to be

39
00:01:44,380 --> 00:01:46,770
activated

40
00:01:54,350 --> 00:01:59,030
once the system has been powered on

41
00:01:56,240 --> 00:02:01,130
it'll be prepared for the fluid

42
00:01:59,030 --> 00:02:03,590
connections which Luca will do from a

43
00:02:01,130 --> 00:02:05,780
different work site on AMS the SSRMS

44
00:02:03,590 --> 00:02:08,119
will carry him from the zenith side to

45
00:02:05,780 --> 00:02:11,380
the aft side here and he slides in to

46
00:02:08,119 --> 00:02:11,380
get ready for those fluid connections

47
00:02:14,150 --> 00:02:18,170
[Music]

48
00:02:16,240 --> 00:02:19,850
there'll be six flu connections

49
00:02:18,170 --> 00:02:22,520
completed here at this VSP worksite

50
00:02:19,850 --> 00:02:25,760
using commercial off-the-shelf wages

51
00:02:22,520 --> 00:02:27,680
thus wages have been encased in a custom

52
00:02:25,760 --> 00:02:29,030
fitting that the engineering team to

53
00:02:27,680 --> 00:02:30,920
develop to allow the astronauts

54
00:02:29,030 --> 00:02:34,450
pressurized gloves to operate the small

55
00:02:30,920 --> 00:02:34,450
Farrell's of the swage

56
00:02:36,430 --> 00:02:41,360
once those six wages are completed the

57
00:02:38,780 --> 00:02:46,069
SSRMS will take Luca to the underside of

58
00:02:41,360 --> 00:02:47,989
AMS for two finals wages drew will have

59
00:02:46,069 --> 00:02:50,060
to pass the tubes from the new pump

60
00:02:47,989 --> 00:02:51,829
system down through a passageway in AMS

61
00:02:50,060 --> 00:02:54,519
to allow Luca to connect those on the

62
00:02:51,829 --> 00:02:54,519
nadir side here

63
00:02:54,700 --> 00:03:00,230
while that NATO worksite Luka will have

64
00:02:57,319 --> 00:03:02,420
to be mindful of several hazards to AMS

65
00:03:00,230 --> 00:03:04,990
and tight clearances while he sweeches

66
00:03:02,420 --> 00:03:04,990
those tubes

67
00:03:09,230 --> 00:03:13,120
[Music]

68
00:03:11,040 --> 00:03:15,280
once complete with the eighths wages

69
00:03:13,120 --> 00:03:21,910
this will allow the engineering teams to

70
00:03:15,280 --> 00:03:23,440
pressurize the system and with the crew

71
00:03:21,910 --> 00:03:24,849
support complete for the day Luca will

72
00:03:23,440 --> 00:03:27,099
ride the assignments back to the forward

73
00:03:24,849 --> 00:03:45,340
side at VSP - and prepare for our

74
00:03:27,099 --> 00:03:46,989
airlock ingress well Lucas riding the

75
00:03:45,340 --> 00:03:49,360
arm drill will be translating back and

76
00:03:46,989 --> 00:03:50,829
starting to bring bags back inside I've

77
00:03:49,360 --> 00:03:54,579
been left out on the ELC over the course

78
00:03:50,829 --> 00:03:56,410
of the e V a series and with both crew

79
00:03:54,579 --> 00:03:59,549
back at the airlock that'll complete EBA

80
00:03:56,410 --> 00:03:59,549
3 of the AMS repair

81
00:04:00,990 --> 00:04:03,050
