houston station on space to ground

2
00:00:06,150 --> 00:00:04,720
welcome to space to ground your weekly

3
00:00:07,909 --> 00:00:06,160
look at what's happening on board the

4
00:00:10,390 --> 00:00:07,919
international space station i'm dan

5
00:00:12,549 --> 00:00:10,400
hewitt crew members spent several days

6
00:00:14,390 --> 00:00:12,559
this week tuning up their spacesuits

00:00:16,630 --> 00:00:14,400
commander butch wilmore and astronaut

8
00:00:18,470 --> 00:00:16,640
samantha chris ferretti worked to swap

9
00:00:21,109 --> 00:00:18,480
out a fan pump separator in one of the

10
00:00:23,029 --> 00:00:21,119
station's suits wilmore and fellow nasa

11
00:00:24,950 --> 00:00:23,039
astronaut terry verts are scheduled to

12
00:00:26,870 --> 00:00:24,960
do three spacewalks starting in late

13
00:00:28,710 --> 00:00:26,880
january to continue preparing the

14
00:00:31,910 --> 00:00:28,720
station for some major rearranging in

15
00:00:33,670 --> 00:00:31,920
the coming year expedition 42 is also

16
00:00:36,470 --> 00:00:33,680
getting ready for a special holiday

17
00:00:39,350 --> 00:00:36,480
delivery in preparation for spacex's

18
00:00:40,950 --> 00:00:39,360
fifth dragon iss resupply mission terry

19
00:00:42,950 --> 00:00:40,960
vert spent some time this week

20
00:00:45,510 --> 00:00:42,960
configuring the device astronauts use to

21
00:00:47,510 --> 00:00:45,520
command visiting spacecraft dragon is

22
00:00:50,389 --> 00:00:47,520
scheduled for launch next week visit

23
00:00:53,029 --> 00:00:50,399
nasa.gov spacex for the latest updates

24
00:00:55,510 --> 00:00:53,039
in coverage time so what do buzz aldrin

25
00:00:57,670 --> 00:00:55,520
shoe the liberty bell and sports arenas

26
00:00:59,670 --> 00:00:57,680
all have in common well they all supply

27
00:01:01,110 --> 00:00:59,680
microbes that are currently growing on

28
00:01:03,830 --> 00:01:01,120
board the station

29
00:01:06,149 --> 00:01:03,840
dub project mercury a huge crowdsource

30
00:01:08,950 --> 00:01:06,159
collection of tiny invisible bacteria

31
00:01:11,590 --> 00:01:08,960
viruses and fungi was flown into space

32
00:01:13,910 --> 00:01:11,600
for study many microbes grow differently

33
00:01:15,670 --> 00:01:13,920
in microgravity offering new insights

34
00:01:18,149 --> 00:01:15,680
that could help researchers develop

35
00:01:19,910 --> 00:01:18,159
helpful antibiotics for space travelers

36
00:01:21,990 --> 00:01:19,920
and earthlings alike

37
00:01:23,830 --> 00:01:22,000
this week the oscar report wants to know

38
00:01:25,830 --> 00:01:23,840
what would happen if you threw something

39
00:01:26,789 --> 00:01:25,840
like a cricket ball at earth from the

40
00:01:28,390 --> 00:01:26,799
station

41
00:01:29,910 --> 00:01:28,400
well we actually have quite a bit of

42
00:01:31,590 --> 00:01:29,920
experience pitching things from the

43
00:01:33,510 --> 00:01:31,600
station towards the earth and they all

44
00:01:35,749 --> 00:01:33,520
pretty much meet the same end when

45
00:01:37,670 --> 00:01:35,759
jettisoning something from iss as

46
00:01:39,830 --> 00:01:37,680
russian space walkers occasionally do

47
00:01:41,910 --> 00:01:39,840
with obsolete parts it will eventually

48
00:01:43,670 --> 00:01:41,920
descend through the earth's atmosphere

49
00:01:45,990 --> 00:01:43,680
and since the object is moving at an

50
00:01:48,550 --> 00:01:46,000
initial speed of over 17

51
00:01:50,630 --> 00:01:48,560
500 miles an hour it will disintegrate

52
00:01:52,310 --> 00:01:50,640
from the heat of re-entry make sure to

53
00:01:54,310 --> 00:01:52,320
