1
00:00:01,896 --> 00:00:03,866
This is Mission Control,
Houston.

2
00:00:03,866 --> 00:00:04,736
Welcome today

3
00:00:04,736 --> 00:00:07,636
to the International Space
Station flight control room

4
00:00:07,636 --> 00:00:10,716
where the team of experts
is watching over the systems

5
00:00:10,716 --> 00:00:12,966
for the International
Space Station

6
00:00:13,246 --> 00:00:16,086
as the crew aboard the station,

7
00:00:16,086 --> 00:00:18,616
Expedition 31 Commander
Oleg Kononenko

8
00:00:18,616 --> 00:00:22,936
and his fellow Russians Gennady
Padalka and Sergei Revin along

9
00:00:22,936 --> 00:00:27,026
with NASA astronauts
Don Pettit and Joe Acaba

10
00:00:27,146 --> 00:00:30,796
and European Space Agency
astronaut Andre Kuipers are

11
00:00:31,226 --> 00:00:34,986
midway through their day, a very
busy day today of preparations

12
00:00:34,986 --> 00:00:39,056
for the departure of the
Dragon commercial spacecraft

13
00:00:39,056 --> 00:00:44,406
from the Earth-facing port
of the Harmony node tomorrow.

14
00:00:45,886 --> 00:00:48,766
The crew has been working
to closeout hatches.

15
00:00:48,766 --> 00:00:50,266
That occurred about
two hours ago,

16
00:00:51,246 --> 00:00:53,766
and we're getting some
live downlink television

17
00:00:53,766 --> 00:00:56,046
as Don Pettit prepares

18
00:00:56,046 --> 00:00:58,116
to put the center cover
over the hatchway.

19
00:00:58,446 --> 00:01:00,526
They've just completed
the installation

20
00:01:00,526 --> 00:01:02,356
of the controller
panel assemblies.

21
00:01:02,356 --> 00:01:04,576
You can see those
four square boxes

22
00:01:04,576 --> 00:01:06,226
around the edges
of the hatchway.

23
00:01:06,576 --> 00:01:11,686
Those are used to control
the 16 bolts that drive

24
00:01:11,686 --> 00:01:15,216
in to provide a snug fit
between visiting spacecraft

25
00:01:15,216 --> 00:01:18,226
and the space station's hatches.

26
00:01:19,396 --> 00:01:21,526
And all that installation
went very well,

27
00:01:21,526 --> 00:01:23,756
and now he's doing the
final installations

28
00:01:23,756 --> 00:01:25,166
of the hatch cover.

29
00:01:25,166 --> 00:01:28,886
They're going to leave one
power cable connected overnight

30
00:01:28,996 --> 00:01:31,746
and then do some final
checkouts of the bolts

31
00:01:31,746 --> 00:01:35,636
and latches tomorrow
before we do the unberthing.

32
00:01:36,026 --> 00:01:39,276
Those activities are
nominal for the release.

33
00:01:39,366 --> 00:01:42,536
Of course the crew also
doing a lot of science work

34
00:01:42,806 --> 00:01:44,476
on the space station today,

35
00:01:44,806 --> 00:01:47,436
working with several different
Russian experiments looking

36
00:01:47,436 --> 00:01:52,976
at the Earth below and how
materials behave in space.

37
00:01:53,266 --> 00:01:55,896
They also are working with
the VIABLE experiment.

38
00:01:55,896 --> 00:01:58,936
That's something that is
being done by Andre Kuipers.

39
00:01:59,086 --> 00:02:02,376
That's a name for the
Process of Relaxation

40
00:02:02,376 --> 00:02:03,526
in the [Ultraviolet]
Band Spectrum

41
00:02:03,526 --> 00:02:06,676
by High-Velocity Interaction
of Exhaust Products,

42
00:02:06,676 --> 00:02:09,006
and that's the Relaksatia
experiment, one of the ones

43
00:02:09,006 --> 00:02:10,896
that the Russian
experiments are working on.

44
00:02:11,526 --> 00:02:14,726
They're also going to be
working on, as mentioned,

45
00:02:14,726 --> 00:02:15,876
the VIABLE experiment.

46
00:02:16,286 --> 00:02:22,756
That VIABLE experiment stands
for eValuatIon And monitoring

47
00:02:22,756 --> 00:02:26,636
of microBiofiLms insidE the
International Space Station,

48
00:02:26,976 --> 00:02:31,516
and it essentially looks at
how microbe films develop

49
00:02:31,516 --> 00:02:34,486
on general surfaces,
both metallic

50
00:02:34,486 --> 00:02:39,676
and fabric inside the space
station so that they can look

51
00:02:39,676 --> 00:02:42,526
for good ways to protect
against a runaway growth

52
00:02:42,526 --> 00:02:45,016
of any of those.

53
00:02:45,756 --> 00:02:48,666
Overall, a very good day
for the International Space

54
00:02:48,666 --> 00:02:49,256
Station crew.

55
00:02:49,256 --> 00:02:51,786
They'll be knocking
off work and trying

56
00:02:51,786 --> 00:02:54,786
to shift their schedule two
hours earlier to get ready

57
00:02:54,786 --> 00:02:57,216
for tomorrow's departure
activities for Dragon.

58
00:02:57,736 --> 00:03:00,886
The release of the
Dragon spacecraft

59
00:03:00,886 --> 00:03:02,616
from the robotic
arm is scheduled

60
00:03:02,616 --> 00:03:05,656
for 4:35 a.m. Central time.

61
00:03:09,306 --> 00:03:12,566
There will be no need
for the use of the lidars

62
00:03:12,566 --> 00:03:15,356
or thermal imagers
as it departs,

63
00:03:15,356 --> 00:03:17,456
but there may be some
testing as they depart

64
00:03:17,456 --> 00:03:18,966
as the opportunity arises.

65
00:03:19,336 --> 00:03:21,786
We'll have Dragon
departure coverage starting

66
00:03:21,786 --> 00:03:23,546
at 1:30 a.m. Central time.

67
00:03:23,926 --> 00:03:27,686
Unberthing is scheduled
for 3:05 a.m. Central time,

68
00:03:27,686 --> 00:03:30,176
and then the release
of Dragon is scheduled

69
00:03:30,176 --> 00:03:32,376
for 4:35 a.m. Central time.

70
00:03:32,376 --> 00:03:36,206
There are going to be several
departure and deorbit burns

71
00:03:36,476 --> 00:03:41,306
that will be following up
on the Dragon departure,

72
00:03:41,806 --> 00:03:46,386
and those all will be
taking place sometime

73
00:03:46,456 --> 00:03:49,116
in the early morning timeframe
for us here in Houston.

74
00:03:52,316 --> 00:03:55,166
But all systems go on the
International Space Station

75
00:03:55,166 --> 00:03:57,576
as the crew is getting
ready to see the departure

76
00:03:57,576 --> 00:03:59,526
of the first commercial
spaceflight

77
00:04:00,116 --> 00:04:02,096
to the International
Space Station.

78
00:04:02,696 --> 00:04:06,766
The station visiting
vehicle Dragon is packed full

79
00:04:06,766 --> 00:04:10,426
of return items, experiment
samples and items that are going

80
00:04:10,426 --> 00:04:14,746
to be refurbished for future
use on board the space station.
