houston station on space to ground

2
00:00:06,789 --> 00:00:05,200
welcome to space to ground your weekly

3
00:00:08,549 --> 00:00:06,799
look at what's happening on board the

4
00:00:10,870 --> 00:00:08,559
international space station i'm dan

5
00:00:13,190 --> 00:00:10,880
hewitt the recent arrival of the new

6
00:00:15,910 --> 00:00:13,200
spacex dragon ship meant one thing this

7
00:00:18,790 --> 00:00:15,920
week for the station crew science time

8
00:00:20,630 --> 00:00:18,800
they dedicated close to 60 hours to work

9
00:00:23,109 --> 00:00:20,640
on research that will be making the

10
00:00:25,029 --> 00:00:23,119
return trip on dragon in may some of

11
00:00:26,710 --> 00:00:25,039
those studies include an investigation

12
00:00:29,109 --> 00:00:26,720
into making bones stay healthy and

13
00:00:30,950 --> 00:00:29,119
strong testing the radiation resistance

14
00:00:33,510 --> 00:00:30,960
of a new material that could one day be

15
00:00:35,910 --> 00:00:33,520
used as a synthetic muscle for robotic

16
00:00:37,510 --> 00:00:35,920
explorers the second round of rodent

17
00:00:40,310 --> 00:00:37,520
research investigations that are

18
00:00:42,869 --> 00:00:40,320
evaluating muscle atrophy eye structure

19
00:00:45,190 --> 00:00:42,879
and bone density changes in microgravity

20
00:00:47,750 --> 00:00:45,200
and the nematode muscle experiment which

21
00:00:49,430 --> 00:00:47,760
uses worms to look at molecular changes

22
00:00:51,430 --> 00:00:49,440
that occur in space

23
00:00:53,110 --> 00:00:51,440
and the benefits for humanity video

24
00:00:54,869 --> 00:00:53,120
series is highlighting a station

25
00:00:56,069 --> 00:00:54,879
technology that's helping the earth

26
00:00:57,990 --> 00:00:56,079
right now

27
00:01:00,549 --> 00:00:58,000
this newest installment features the

28
00:01:03,189 --> 00:01:00,559
hyperspectral imager for coastal oceans

29
00:01:05,750 --> 00:01:03,199
or hico a specialized imaging device

30
00:01:08,070 --> 00:01:05,760
that allowed scientists to literally see

31
00:01:10,149 --> 00:01:08,080
in a whole new light providing important

32
00:01:12,469 --> 00:01:10,159
data on water quality that affects

33
00:01:15,109 --> 00:01:12,479
millions of americans head over to

34
00:01:17,270 --> 00:01:15,119
nasa.gov station benefits to watch the

35
00:01:19,749 --> 00:01:17,280
full video and learn other ways we're

36
00:01:21,749 --> 00:01:19,759
working off the earth for the earth

37
00:01:23,990 --> 00:01:21,759
this week we have a question we'd like

38
00:01:26,469 --> 00:01:24,000
you to answer where over the world is

39
00:01:28,469 --> 00:01:26,479
astronaut scott kelly in this new

40
00:01:30,630 --> 00:01:28,479
contest the one-year crew member will

41
00:01:33,270 --> 00:01:30,640
tweet out a photo of a new geographic

42
00:01:34,870 --> 00:01:33,280
location each wednesday the first person

43
00:01:36,789 --> 00:01:34,880
to reply to the tweet correctly

44
00:01:39,910 --> 00:01:36,799
identifying the location will win a

45
00:01:41,510 --> 00:01:39,920
photo print of it autographed by kelly

46
00:01:44,069 --> 00:01:41,520
follow him on twitter at station

47
00:01:45,670 --> 00:01:44,079
commander kelly and good luck meanwhile

48
00:01:47,749 --> 00:01:45,680
