1
00:00:01,256 --> 00:00:03,346
Good morning and welcome
to Mission Control Houston.

2
00:00:03,346 --> 00:00:08,236
We're inside the International Space Station
flight control room for today's ISS Update.

3
00:00:08,786 --> 00:00:10,886
It is Wednesday, January 18.

4
00:00:11,666 --> 00:00:16,256
The team here in the flight control room is
watching over systems aboard the space station

5
00:00:17,116 --> 00:00:20,576
and following along with the
activities of the Expedition 30 crew.

6
00:00:21,976 --> 00:00:31,986
The crew on board the space station is
working through the mid-afternoon of its day,

7
00:00:32,416 --> 00:00:37,436
focusing on science experiments and maintenance
and stowage on board the space station today.

8
00:00:37,766 --> 00:00:43,706
First up today, all of the crew members
participated in a fire drill to go

9
00:00:43,706 --> 00:00:47,026
through the procedures if there
were such an emergency on board.

10
00:00:48,446 --> 00:00:53,476
And then they separated off into
various tasks around the space station.

11
00:00:54,516 --> 00:00:58,196
Space station Commander Dan
Burbank did some sampling

12
00:00:58,196 --> 00:01:05,416
of the surfaces inside the space station to
return those samples for analysis on Earth.

13
00:01:06,386 --> 00:01:10,436
He is also doing some maintenance on
the Advanced Resistive Exercise Device,

14
00:01:10,766 --> 00:01:13,476
which is an exercise machine
on board the station

15
00:01:13,476 --> 00:01:17,326
that helps simulate weight lifting
in a microgravity environment.

16
00:01:17,806 --> 00:01:26,486
NASA astronaut Don Pettit was working with
a science experiment that is ongoing now,

17
00:01:26,486 --> 00:01:32,336
as he is performing an ultrasound
scan on himself with the assistance

18
00:01:32,336 --> 00:01:35,376
of European Space Agency
astronaut Andre Kuipers.

19
00:01:36,136 --> 00:01:39,196
This is part of the Integrated
Cardiovascular experiment.

20
00:01:40,136 --> 00:01:45,886
The crew performs a resting scan with remote
guidance from the team on the ground to help

21
00:01:45,966 --> 00:01:48,316
with using the ultrasound equipment.

22
00:01:48,646 --> 00:01:55,266
The Integrated Cardiovascular experiment
investigates the magnitude of the left

23
00:01:55,266 --> 00:01:59,836
and right ventricular atrophy, or
decrease in the size of the heart muscle,

24
00:02:00,336 --> 00:02:02,776
that is associated with long-duration
spaceflight.

25
00:02:03,596 --> 00:02:05,926
That measurement is done using MRI.

26
00:02:06,696 --> 00:02:10,836
And also the experiment relates
this type of atrophy to measures

27
00:02:10,836 --> 00:02:14,296
of physical activity and cardiac work in flight.

28
00:02:14,446 --> 00:02:19,906
That is done by crew members wearing
a monitor or halter for several days

29
00:02:19,956 --> 00:02:22,646
at a time to monitor their activities.

30
00:02:22,676 --> 00:02:27,616
And then also the ultrasound is used for
this experiment to determine the time,

31
00:02:27,616 --> 00:02:32,166
course and pattern of the progression
of the cardiac atrophy in flight

32
00:02:32,466 --> 00:02:35,806
by using the ultrasound to
do a scan of the chest.

33
00:02:39,126 --> 00:02:43,636
Pettit was the subject of the scan
today with Kuipers' assistance,

34
00:02:43,636 --> 00:02:46,476
and actually Kuipers is involved
in the experiment as well,

35
00:02:46,626 --> 00:02:51,636
as he's wearing the halter
monitor as part of the experiment

36
00:02:51,636 --> 00:02:54,566
to study his activity for a few days.

37
00:02:54,566 --> 00:02:57,126
He has that to wear for another 24 hours.

38
00:02:57,356 --> 00:03:02,166
Kuipers also connected with students today.

39
00:03:02,166 --> 00:03:07,276
Earlier, he conducted an amateur
radio pass to speak with students

40
00:03:07,276 --> 00:03:12,546
at an industrial technical school in Belgium,
and he's also helping with the sampling

41
00:03:12,546 --> 00:03:14,446
of the environment on board the station

42
00:03:15,216 --> 00:03:18,376
with analyzing some surface
samples and water samples.

43
00:03:19,156 --> 00:03:22,416
Elsewhere on board the space station,

44
00:03:22,416 --> 00:03:24,976
the cosmonauts are working
inside the Russian segment.

45
00:03:25,566 --> 00:03:32,206
Anton Shkaplerov is performing a periodic
fitness evaluation today while exercising

46
00:03:32,206 --> 00:03:38,876
on a treadmill and working on some
stowage audits inside the Russian segment.

47
00:03:38,876 --> 00:03:43,476
Anatoly Ivanishin and Oleg Kononenko
are both working on different activities

48
00:03:43,476 --> 00:03:51,276
to help stow unneeded equipment inside the 45
Progress cargo vehicle as that will be undocked

49
00:03:51,726 --> 00:03:55,316
and commanded to burn up in the
Earth's atmosphere eventually.

50
00:03:55,516 --> 00:03:57,206
Its undocking is scheduled for Monday.

51
00:03:57,206 --> 00:04:05,796
And while the crew members are
working on board the space station,

52
00:04:05,796 --> 00:04:09,666
there's some work being commanded from
the ground here in Mission Control.

53
00:04:10,136 --> 00:04:14,216
The robotics flight controllers are
operating the robotics systems on the outside

54
00:04:14,216 --> 00:04:19,566
of the space station, moving the Mobile
Transporter, which is atop the railway

55
00:04:19,566 --> 00:04:23,006
of the truss structure - the
backbone of the space station.

56
00:04:23,766 --> 00:04:30,356
That transporter is being moved about 100
feet down the truss towards the port side,

57
00:04:30,916 --> 00:04:36,776
getting closer to a location on the P3, or
Port 3, truss where a platform is located,

58
00:04:37,266 --> 00:04:39,646
and a science experiment
is on top of that platform.

59
00:04:40,356 --> 00:04:46,966
On Thursday, the Mobile Transporter will be
in place with the space station's robotic arm

60
00:04:47,216 --> 00:04:53,936
and the Dextre Special Purpose Dextrous
Manipulator on it to perform a survey

61
00:04:54,076 --> 00:04:57,256
of an experiment that's located
on that platform.

62
00:04:57,306 --> 00:05:02,636
It's called the Space Test Program
Houston-3 experiment, which is a compliment

63
00:05:02,636 --> 00:05:07,756
of four individual experiments actually that
are testing concepts aboard the space station

64
00:05:07,756 --> 00:05:09,606
for future long-duration missions.

65
00:05:11,116 --> 00:05:16,036
That experiment was installed during
the STS-134 mission in cooperation

66
00:05:16,206 --> 00:05:18,816
with the DOD Space Test Program Houston office.

67
00:05:19,366 --> 00:05:27,226
The flight control team has completed the
first phase of the software transition planned

68
00:05:27,546 --> 00:05:32,376
for this month aboard the station that
began on Sunday and lasted three days,

69
00:05:32,886 --> 00:05:36,556
upgrading the software on the major
computers aboard the space station,

70
00:05:36,556 --> 00:05:42,966
the ones that perform the command and control
of the complex and some other computers

71
00:05:43,016 --> 00:05:47,986
and the laptops inside the space
station that the crew members use

72
00:05:47,986 --> 00:05:49,816
to interface with the station systems.
