00:00:11,509 --> 00:00:09,350
it is thursday april 25th and the six

2
00:00:13,669 --> 00:00:11,519
human beings who are not on planet earth

3
00:00:15,589 --> 00:00:13,679
have spent this day taking care of the

4
00:00:17,510 --> 00:00:15,599
equipment that takes care of them on

5
00:00:19,429 --> 00:00:17,520
board the international space station

6
00:00:21,750 --> 00:00:19,439
and supporting a number of the science

7
00:00:23,670 --> 00:00:21,760
experiments that they're pursuing during

8
00:00:25,589 --> 00:00:23,680
expedition 35.

9
00:00:27,589 --> 00:00:25,599
after a morning planning conference

10
00:00:29,029 --> 00:00:27,599
today with the flight control teams all

11
00:00:31,429 --> 00:00:29,039
around the world commander chris

12
00:00:33,590 --> 00:00:31,439
hadfield used a vacuum cleaner for some

13
00:00:36,150 --> 00:00:33,600
routine cleaning of pressure release

14
00:00:39,030 --> 00:00:36,160
valves and the cabin depressurization

15
00:00:41,590 --> 00:00:39,040
assembly in the european space agency's

16
00:00:43,990 --> 00:00:41,600
columbus module he then moved to the

17
00:00:46,229 --> 00:00:44,000
station's airlock and spent time doing

18
00:00:48,950 --> 00:00:46,239
preventive maintenance on the spacesuits

19
00:00:51,029 --> 00:00:48,960
that are worn for spacewalks on the u.s

20
00:00:53,189 --> 00:00:51,039
segment of the space station he was

21
00:00:56,950 --> 00:00:53,199
cycling the pressure valves on those

22
00:00:58,950 --> 00:00:56,960
emu's and cleaning the cooling loops

23
00:01:01,590 --> 00:00:58,960
flight engineer pavel vinogradov started

24
00:01:04,229 --> 00:01:01,600
his day in the piers docking compartment

25
00:01:06,230 --> 00:01:04,239
stowing the orlan space suits and

26
00:01:08,870 --> 00:01:06,240
putting the last of the systems back

27
00:01:10,870 --> 00:01:08,880
into normal configuration after the

28
00:01:13,510 --> 00:01:10,880
spacewalk he conducted with flight

29
00:01:15,990 --> 00:01:13,520
engineer roman romanenko last week

30
00:01:19,190 --> 00:01:16,000
romanenko joined him for those tasks

31
00:01:22,149 --> 00:01:19,200
after he had an exercise session wearing

32
00:01:25,749 --> 00:01:22,159
a lower body negative pressure suit that

33
00:01:28,550 --> 00:01:25,759
uses a vacuum pull to assimilate gravity

34
00:01:30,950 --> 00:01:28,560
for the wearer it's a usual protocol for

35
00:01:33,990 --> 00:01:30,960
cosmonauts who are getting close to

36
00:01:36,149 --> 00:01:34,000
returning to earth romanenko hadfield

37
00:01:38,710 --> 00:01:36,159
and flight engineer tom marshburn are

38
00:01:41,749 --> 00:01:38,720
due to come home in mid-may when they

39
00:01:43,670 --> 00:01:41,759
will have finished up about 140 days in

40
00:01:46,230 --> 00:01:43,680
space on this mission

41
00:01:48,710 --> 00:01:46,240
flight engineer marshburn spent most of

42
00:01:51,670 --> 00:01:48,720
his day working with a life-size robot

43
00:01:53,830 --> 00:01:51,680
robonaut 2 is a technology demonstration

44
00:01:56,069 --> 00:01:53,840
aimed at developing better robotics for

45
00:01:58,310 --> 00:01:56,079
use in future exploration including

46
00:02:00,870 --> 00:01:58,320
robots that can do work

47
00:02:04,230 --> 00:02:00,880
today marshburn tele-robotically

48
00:02:06,709 --> 00:02:04,240
operated r2 via voice commands and

49
00:02:08,869 --> 00:02:06,719
wearing of a special helmet and gloves

50
00:02:11,270 --> 00:02:08,879
that translate his movements into the

51
00:02:13,270 --> 00:02:11,280
robot's movements this is all done with

52
00:02:15,350 --> 00:02:13,280
the intent to develop the robot that

53
00:02:16,949 --> 00:02:15,360
could do work outside of the station

54
00:02:19,750 --> 00:02:16,959
without risking crew members on a

55
00:02:23,110 --> 00:02:19,760
spacewalk as well as do more repetitive

56
00:02:24,949 --> 00:02:23,120
tasks that take place inside the station

57
00:02:27,750 --> 00:02:24,959
flight engineer alexander misurkin

58
00:02:29,910 --> 00:02:27,760
started assisting roman romanenko with

59
00:02:32,309 --> 00:02:29,920
his lower body negative pressure

60
00:02:34,949 --> 00:02:32,319
exercise this morning and then spent the

61
00:02:38,070 --> 00:02:34,959
rest of his morning working with russian

62
00:02:40,710 --> 00:02:38,080
science experiments after lunch misurkin

63
00:02:43,270 --> 00:02:40,720
did maintenance at the progress vehicle

64
00:02:46,309 --> 00:02:43,280
at the piers module emptying its water

65
00:02:48,309 --> 00:02:46,319
storage tanks while romanenko and

66
00:02:50,309 --> 00:02:48,319
vinogradov did more training with the

67
00:02:52,390 --> 00:02:50,319
toru system which allows crews to

68
00:02:54,550 --> 00:02:52,400
manually fly an approaching russian

69
00:02:56,229 --> 00:02:54,560
spacecraft if the automatic docking

70
00:02:58,149 --> 00:02:56,239
system failed

71
00:03:00,550 --> 00:02:58,159
hadfield spent his afternoon wrapping up

72
00:03:03,270 --> 00:03:00,560
the spacesuit maintenance and also

73
00:03:05,670 --> 00:03:03,280
conducted an amateur radio contact with

74
00:03:07,750 --> 00:03:05,680
students in far northern canada to

75
00:03:10,070 --> 00:03:07,760
answer questions about his mission

76
00:03:12,309 --> 00:03:10,080
cassidy and marshburn have a similar

77
00:03:14,470 --> 00:03:12,319
thing on their plan for the day talking

78
00:03:17,190 --> 00:03:14,480
with reporters at a portland maine

79
00:03:18,949 --> 00:03:17,200
television station and the sirius xm

80
00:03:21,430 --> 00:03:18,959
radio about the work that they've been

81
00:03:22,949 --> 00:03:21,440
doing during their time on board

82
00:03:25,190 --> 00:03:22,959
crews also been getting ready for the

83
00:03:27,750 --> 00:03:25,200
scheduled arrival of a new shipment of

84
00:03:29,910 --> 00:03:27,760
supplies in a progress cargo ship which

85
00:03:32,229 --> 00:03:29,920
launched on wednesday from the baikonur

86
00:03:36,149 --> 00:03:32,239
cosmodrome and is due at the zvezda

87
00:03:39,030 --> 00:03:36,159
modules docking port at 7 26 a.m houston

88
00:03:41,430 --> 00:03:39,040
time on friday the mission managers are

89
00:03:44,390 --> 00:03:41,440
still looking into options for ways to

90
00:03:47,270 --> 00:03:44,400
deploy a navigation antenna that failed

91
00:03:49,990 --> 00:03:47,280
to deploy yesterday those meetings still

92
00:03:51,750 --> 00:03:50,000
underway the crew members on board are

93
00:03:54,070 --> 00:03:51,760
looking forward to getting into that

94
00:03:56,309 --> 00:03:54,080
ship and unloading the fresh food and

95
00:03:58,229 --> 00:03:56,319
other goodies while they take time off

96
00:04:00,390 --> 00:03:58,239
duty over the weekend to get set for
