chilly night over in kazakhstan

15
00:00:31,589 --> 00:00:29,679

carefully planned journey the spacecraft

astronaut cho lindgren used the

25
00:00:49,350 --> 00:00:47,280
station's robotic arm to grapple the

26
00:00:51,750 --> 00:00:49,360

32
00:01:01,750 --> 00:00:59,199
way for very long

kazakhstan since november 30th preparing

41
00:01:18,390 --> 00:01:16,799
for their trip to the station they've

42
00:01:20,390 --> 00:01:18,400
tried on their spacesuits inspected

43
00:01:22,230 --> 00:01:20,400
their soyuz spacecraft and brushed up on

44
00:01:24,149 --> 00:01:22,240
training they even found a little time

45
00:01:25,109 --> 00:01:24,159
to relax ahead of their december 15th

46
00:01:27,429 --> 00:01:25,119

this week's twitter question comes from

00:01:36,870 --> 00:01:34,960
amy blive whose first grade class wants

52
00:01:38,390 --> 00:01:36,880
to know if astronauts can get a cold or

53
00:01:40,789 --> 00:01:38,400
the flu in space

54
00:01:41,830 --> 00:01:40,799
the short answer is yes but it's highly

55
00:01:43,190 --> 00:01:41,840
unlikely

56
00:01:45,190 --> 00:01:43,200
some of the astronauts have come down

57
00:01:46,789 --> 00:01:45,200
with infections in the past but nasa has

58
00:01:48,950 --> 00:01:46,799
developed procedures to be certain that

59
00:01:50,870 --> 00:01:48,960
no bacterium or virus ever enters the

60
00:01:52,389 --> 00:01:50,880
station that's how astronauts got stuck

61
00:01:54,469 --> 00:01:52,399
with house cleaning duties every

62
00:01:56,149 --> 00:01:54,479
saturday but in the rare event that an

63
00:01:57,749 --> 00:01:56,159
astronaut does get sick they have a

64
00:01:59,910 --> 00:01:57,759
small pharmacy on board that can help

65
00:02:01,109 --> 00:01:59,920
counter most symptoms keep sending us
