13
00:00:37,270 --> 00:00:34,719
primary objectives of the spacewalk are

14
00:00:39,350 --> 00:00:37,280
to relocate an external control panel

15
00:00:41,670 --> 00:00:39,360
for the european robotic arm from one

16
00:00:43,590 --> 00:00:41,680
operating area to another and test a

17
00:00:45,590 --> 00:00:43,600
rigidizing mechanism on the arm that

18
00:00:46,950 --> 00:00:45,600
will be used to facilitate the grasping

21
00:00:52,950 --> 00:00:51,440
for a launch on a soyuz rocket later

22
00:00:55,350 --> 00:00:52,960

gagarin cosmonaut training center in

29
00:01:10,630 --> 00:01:08,720
star city russia the training is taking

30
00:01:12,310 --> 00:01:10,640
place ahead of their upcoming launch to

31
00:01:14,310 --> 00:01:12,320
the international space station

32
00:01:16,630 --> 00:01:14,320
scheduled to launch wednesday september

33
00:01:19,109 --> 00:01:16,640
21st from the baikonur cosmodrome in

34
00:01:20,870 --> 00:01:19,119
kazakhstan the crew is scheduled for a

35
00:01:22,630 --> 00:01:20,880
six-month stay at the orbiting

36
00:01:24,870 --> 00:01:22,640
laboratory

37
00:01:26,870 --> 00:01:24,880
studying protein crystals can contribute

38
00:01:28,950 --> 00:01:26,880
to the development of disease fighting

39
00:01:30,950 --> 00:01:28,960
drugs and new materials

40
00:01:32,870 --> 00:01:30,960
scientists have long found that protein

41
00:01:35,109 --> 00:01:32,880
crystal growth in the microgravity

42
00:01:37,030 --> 00:01:35,119
environment of space are of higher

43
00:01:37,830 --> 00:01:37,040
quality than protein crystals grown on

44
00:01:40,149 --> 00:01:37,840
earth

45
00:01:42,149 --> 00:01:40,159
this week nasa astronaut chell lingard

46
00:01:44,310 --> 00:01:42,159
worked on the advanced nanostep

47
00:01:46,469 --> 00:01:44,320
experiment which aims to improve the

48
00:01:48,550 --> 00:01:46,479
quality of space grown crystals while

49
00:01:50,630 --> 00:01:48,560
utilizing shorter sample preparation

50
00:01:52,710 --> 00:01:50,640
periods and learn more about what kinds

51
00:01:54,870 --> 00:01:52,720
of impurities deteriorate protein

52
00:01:57,429 --> 00:01:54,880
crystal quality grown in space

53
00:01:59,270 --> 00:01:57,439
advanced nanostep uses special equipment

54
00:02:01,350 --> 00:01:59,280
to measure crystal growth rates

55
00:02:03,670 --> 00:02:01,360
nucleation rates and study of the

56
00:02:06,069 --> 00:02:03,680
surface structure of the crystals this

57
00:02:08,389 --> 00:02:06,079
information may advance capabilities for

58
00:02:10,790 --> 00:02:08,399
the research and production of materials

59
00:02:12,550 --> 00:02:10,800
and drugs in space and contributes to a

60
00:02:14,630 --> 00:02:12,560
working body of knowledge concerning the

61
00:02:16,550 --> 00:02:14,640
biochemistry of organisms in

62
00:02:18,630 --> 00:02:16,560
microgravity

63
00:02:20,790 --> 00:02:18,640
and that's space to ground for this week

64
00:02:23,350 --> 00:02:20,800
