1
00:00:01,826 --> 00:00:03,366
This is Mission Control Houston.

2
00:00:03,366 --> 00:00:07,956
Welcome to today's ISS update
for Friday, February 17, 2012.

3
00:00:07,956 --> 00:00:11,736
This is a live view inside the International
Space Station's Flight Control Room here

4
00:00:11,736 --> 00:00:12,856
at the Johnson Space Center.

5
00:00:14,596 --> 00:00:15,836
This team here is being led today

6
00:00:15,836 --> 00:00:18,186
by Flight Director Mike Sarafin
who is there in the middle.

7
00:00:18,186 --> 00:00:23,086
Sitting beside him is Tony Ceccaci a
former fellow shuttle flight director.

8
00:00:23,086 --> 00:00:27,076
He is also sitting on console getting
trained on the space station and its systems.

9
00:00:27,696 --> 00:00:31,696
Sitting beside them both as the
Capcom is astronaut Kjell Lindgren.

10
00:00:32,086 --> 00:00:34,276
He is the voice of the team here in Houston

11
00:00:34,676 --> 00:00:38,206
to the Expedition 30 crew aboard
the International Space Station.

12
00:00:39,716 --> 00:00:40,576
There's a look at the crew.

13
00:00:40,576 --> 00:00:42,516
The crew has a very busy Friday on tap for them.

14
00:00:42,516 --> 00:00:47,416
Don Pettit who is on the far right has
been working on an experiment called SLICE.

15
00:00:48,236 --> 00:00:52,136
This stands for the Structure and
Liftoff in Combustion Experiment.

16
00:00:52,136 --> 00:00:57,336
What it does is take a look at how
different flames perform in space.

17
00:00:57,336 --> 00:01:02,146
There is a phenomena called liftoff which is
where the flame actually comes up off the burner

18
00:01:02,486 --> 00:01:05,076
and this is caused by a series
of different things,

19
00:01:05,076 --> 00:01:09,436
whether its the combustion elements
themselves, what makes up the flame

20
00:01:09,736 --> 00:01:11,766
or the different type of flow that is happening.

21
00:01:11,766 --> 00:01:16,196
Obviously, flames behave a bit differently
up in space than they do here on the ground.

22
00:01:16,666 --> 00:01:22,386
But by studying this liftoff phenomena, as
we talked about, it is hoped that teams are

23
00:01:22,386 --> 00:01:27,396
in the ground can design better
products that have better fuel efficiency

24
00:01:27,716 --> 00:01:29,846
or a better combustion inside of them.

25
00:01:30,236 --> 00:01:32,986
Pettit is also working today
on some routine maintenance

26
00:01:32,986 --> 00:01:35,276
on the robotic workstation
that is down in the cupola.

27
00:01:35,276 --> 00:01:39,476
This is sort of the windows on the world
module of the International Space Station.

28
00:01:39,476 --> 00:01:41,016
There is a robotics workstation there

29
00:01:41,376 --> 00:01:46,016
that is used anytime the crew is
operating the station's robotic arm

30
00:01:46,336 --> 00:01:48,756
so he will take care of that
later on this afternoon.

31
00:01:50,186 --> 00:01:53,076
Meanwhile, Anatoly Ivanishin,
another member of Expedition 30,

32
00:01:53,076 --> 00:01:56,746
is working on opening the transfer hatch
between the Pirs docking compartment,

33
00:01:56,746 --> 00:02:02,106
which is the site of yesterday's
spacewalk, and the Progress 46 cargo craft.

34
00:02:02,186 --> 00:02:06,346
Those hatches were closed obviously because
the cosmonauts were opening up a hatch on Pirs

35
00:02:06,346 --> 00:02:09,976
and decompressing it so they could
step outside so they had to seal off

36
00:02:09,976 --> 00:02:11,966
that Progress cargo craft, which you see the lay

37
00:02:11,966 --> 00:02:14,946
out of the station there
docked back there with Pirs.

38
00:02:14,946 --> 00:02:19,416
So that will take care of opening
that hatch back up later on today.

39
00:02:21,486 --> 00:02:24,886
Andre Kuipers is working on
an experiment called MARES.

40
00:02:25,026 --> 00:02:28,276
This is the Muscle Atrophy
Research and Exercise System.

41
00:02:29,096 --> 00:02:33,026
It's sort of an exercise system that you
would...looks like something you would find

42
00:02:33,026 --> 00:02:36,046
on the ground here in a gym but
operates a little bit differently.

43
00:02:36,046 --> 00:02:40,526
This item measures and exercises seven
different joints to see what happens

44
00:02:41,146 --> 00:02:43,116
to the crew members bodies as they all live

45
00:02:43,116 --> 00:02:45,976
up on board the International
Space Station for up to six months.

46
00:02:48,376 --> 00:02:53,026
Monitoring the body's performance and how
it adapts to space is incredibly important

47
00:02:53,026 --> 00:02:56,256
and one of the main things that the
International Space Station is teaching us.

48
00:02:56,866 --> 00:03:00,956
Obviously, those lessons will be very important
as humans venture beyond low Earth orbit

49
00:03:01,286 --> 00:03:04,296
and head to even further
destinations out in space.

50
00:03:04,546 --> 00:03:06,996
Kuipers also working on the cabin fan assemblies

51
00:03:06,996 --> 00:03:11,366
and ventilation ducts there inside the
Columbus module later on this afternoon.

52
00:03:13,226 --> 00:03:18,936
Oleg Kononenko and Anton Shkaplerov
are taking care of quite a number

53
00:03:18,936 --> 00:03:22,046
of different activities today and also
recovering from yesterday's spacewalk.

54
00:03:22,046 --> 00:03:25,186
That spacewalk lasted six hours and 15 minutes.

55
00:03:25,676 --> 00:03:29,826
They'll be talking with ground controllers
today to review yesterday's spacewalk and talk

56
00:03:30,346 --> 00:03:33,876
about everything that was
accomplished during that spacewalk.

57
00:03:33,876 --> 00:03:35,706
They completed move of the Strela boom.

58
00:03:35,706 --> 00:03:39,816
This is one of the two large
extension booms that are on the outside

59
00:03:39,816 --> 00:03:41,406
of the Russian segment of the station.

60
00:03:41,406 --> 00:03:47,306
They use these to move around and to gain access
to different portions of the Russian segment.

61
00:03:47,656 --> 00:03:51,306
Strela 1 used to be on the Pirs docking
compartment which is on the bottom side

62
00:03:51,306 --> 00:03:55,056
of the station, the earth facing
side of that part of the complex.

63
00:03:55,386 --> 00:03:59,116
They moved it up to the Poisk module
which is directly up above Pirs

64
00:03:59,116 --> 00:04:02,506
on the space-facing side of the Russian segment.

65
00:04:03,586 --> 00:04:06,616
There is another boom called Strela
2 that is still down on Poisk.

66
00:04:06,616 --> 00:04:09,166
That will be moved...down on Pirs.

67
00:04:09,166 --> 00:04:09,536
Excuse me.

68
00:04:09,536 --> 00:04:13,646
That will be moved later on
this summer by a future crew.

69
00:04:13,946 --> 00:04:18,656
These Strela booms that you see the crew
moving yesterday are being moved up to the top

70
00:04:18,656 --> 00:04:21,896
of the station to make way
for the departure of Pirs.

71
00:04:22,236 --> 00:04:25,526
That particular portion of the station
has been up there for more than 10 years

72
00:04:25,856 --> 00:04:30,936
and it will say goodbye as it makes way for
a brand-new Multipurpose Laboratory Module

73
00:04:31,216 --> 00:04:34,996
that our Russian counterparts will
be launching later on next year.

74
00:04:37,796 --> 00:04:41,226
Dan Burbank, the Commander of Expedition
30, is working on quite a number

75
00:04:41,226 --> 00:04:43,326
of different experiments today including MELFI.

76
00:04:43,326 --> 00:04:45,036
This is the Minus-Eighty Laboratory.

77
00:04:45,036 --> 00:04:50,316
This is the large freezer on board the station
that is used to store different types of samples

78
00:04:50,316 --> 00:04:53,486
and experiments at really,
really cold temperatures.

79
00:04:53,486 --> 00:04:55,176
You are seeing a picture of it here.

80
00:04:55,526 --> 00:04:59,666
He is basically going to be doing a
nitrogen pressure check just to make sure

81
00:04:59,666 --> 00:05:01,586
that MELFI is operating as expected.

82
00:05:01,826 --> 00:05:05,586
He is also going to be working
on an experiment called BCAT-6.

83
00:05:05,586 --> 00:05:08,076
This is the Binary Colloidal Alloy Test.

84
00:05:09,466 --> 00:05:13,326
And he and the rest of the crew members also
have several different Crew Earth Observation

85
00:05:13,326 --> 00:05:14,326
opportunities today.

86
00:05:14,326 --> 00:05:17,786
They will be flying directly
above Chile and will have a chance

87
00:05:17,786 --> 00:05:19,516
to take look a down at the Woollya Cove.

88
00:05:19,516 --> 00:05:22,526
This is an H.M.S. Beagle landing site.

89
00:05:22,786 --> 00:05:27,636
And they will also be flying over
the St. Helena Island which is off

90
00:05:27,636 --> 00:05:30,636
in the Atlantic Ocean off the coast of Africa.
