1
00:00:01,583 --> 00:00:05,600
Russian spacewalk 56 will be conducted
by Sergei Prokopyev,

2
00:00:05,600 --> 00:00:09,916
EV1 in the red stripes and Dmitri Petelin,
EV2 in the blue stripes.

3
00:00:09,916 --> 00:00:13,766
Anna Kikina will assist a suit IV

4
00:00:13,800 --> 00:00:17,783
and European robotic arm-ERA- operator.

5
00:00:17,783 --> 00:00:23,033
To start the spacewalk, crew will egress
the Poisk airlock with a tool carrier,

6
00:00:23,033 --> 00:00:29,633
crew lock bag and an adapter to assist
with ERA operations.

7
00:00:29,633 --> 00:00:32,883
After securing the adapter on the Strela 1
translation ring,

8
00:00:33,683 --> 00:00:36,766
crew will translate to the port
side of the Poisk module.

9
00:00:37,883 --> 00:00:43,066
Here, they will retrieve the ERA adapter.

10
00:00:43,066 --> 00:00:46,316
Sergei and Dmitri will move along
the Strela 2 boom and continue

11
00:00:46,316 --> 00:00:50,516
Nader to the Rassvet module.

12
00:00:50,516 --> 00:00:53,850
Dmitri will temporarily
stow the ERA adapter on a nearby

13
00:00:53,850 --> 00:00:56,250
handrail.

14
00:00:59,966 --> 00:01:02,516
Crew will move further Nader
to the radiator worksite

15
00:01:02,966 --> 00:01:06,350
where they'll first work
to disconnect a radiator cable, cap

16
00:01:06,350 --> 00:01:11,333
it and set it aside.

17
00:01:11,333 --> 00:01:15,350
Nearby, the two will remove a protective
cover from the radiator, close

18
00:01:15,350 --> 00:01:19,250
the fluid connectors,
then remove the protective cover.

19
00:01:23,783 --> 00:01:26,600
Each crew member will open a Nader
radiator

20
00:01:26,633 --> 00:01:29,716
launch lock,
then translate zenith to release two more

21
00:01:29,716 --> 00:01:31,350
launch locks.

22
00:01:36,266 --> 00:01:38,516
While the ERAgrapples onto the radiator,

23
00:01:38,850 --> 00:01:44,250
Dmitri and Sergei will monitor
the robotic motion.

24
00:01:44,250 --> 00:01:48,050
Once motion is complete,
they'll close MLI flaps over

25
00:01:48,233 --> 00:01:53,100
the launch locks.

26
00:01:53,100 --> 00:01:56,300
The team will retrieve
the previously stowed ERA adapter

27
00:01:56,300 --> 00:02:00,450
and install it on the Strella adapter.

28
00:02:02,216 --> 00:02:04,350
Sergei removes the protective cover

29
00:02:04,350 --> 00:02:08,883
and further configures
the ERA adapter booms.

30
00:02:10,216 --> 00:02:13,016
Both crew will begin a long translation
zenith

31
00:02:13,050 --> 00:02:15,150
to the Zaria module,

32
00:02:22,516 --> 00:02:23,866
translate aft

33
00:02:23,866 --> 00:02:28,250
along Stella 2 to Poisk,
then continue on to Strella 1

34
00:02:28,733 --> 00:02:31,433
down to the Nauka module
where they’ll arrive

35
00:02:31,433 --> 00:02:40,350
at the next worksite.

36
00:02:42,300 --> 00:02:43,700
Dmitri and Sergei will work

37
00:02:43,700 --> 00:02:48,083
together to make three connections
on a cable, inspect screws

38
00:02:48,233 --> 00:02:52,650
and remove
a protective cover from the interface.

39
00:02:55,766 --> 00:02:56,250
Crew will

40
00:02:56,250 --> 00:02:59,816
move to a monitoring position
and provide a go to Anna

41
00:03:00,266 --> 00:03:03,616
to maneuver the radiator
in for mating to the Nauka module.

42
00:03:09,716 --> 00:03:11,416
After mating the radiator,

43
00:03:11,416 --> 00:03:14,516
both crew will perform final mechanical,
hydraulic

44
00:03:14,700 --> 00:03:26,000
and electrical connections.

45
00:03:26,000 --> 00:03:34,616
From there, they'll translate
back up Strela 1 to the Poisk airlock.

46
00:03:34,616 --> 00:03:37,816
Sergei will secure a jettison bundle
to Strela 1

47
00:03:38,866 --> 00:03:41,333
and after performing a tool inventory,
Sergei

48
00:03:41,333 --> 00:03:44,066
and Dmitri will ingress the airlock
and close the hatch.

49
00:03:44,400 --> 00:03:54,733
Ending Russian Spacewalk 56.
