00:00:07,030 --> 00:00:05,030
houston station on space to ground

2
00:00:09,990 --> 00:00:07,040
welcome to space to ground i'm sandra

3
00:00:11,990 --> 00:00:10,000
jones this week four humans successfully

4
00:00:13,990 --> 00:00:12,000
splashed down in the gulf of mexico

5
00:00:16,150 --> 00:00:14,000
after a nearly six month mission in

6
00:00:18,390 --> 00:00:16,160
space and science abounds on the

7
00:00:20,390 --> 00:00:18,400
international space station

8
00:00:22,950 --> 00:00:20,400
dragon spacex on the big loop all hooks

9
00:00:25,589 --> 00:00:22,960
open and nominal

10
00:00:28,870 --> 00:00:25,599
and happens we see separation

11
00:00:31,349 --> 00:00:28,880
on sunday may 2nd spacex's crew dragon

12
00:00:33,430 --> 00:00:31,359
carrying nasa astronauts michael hopkins

13
00:00:36,470 --> 00:00:33,440
victor glover and shannon walker and

14
00:00:38,950 --> 00:00:36,480
japan aerospace exploration agency

15
00:00:41,030 --> 00:00:38,960
astronaut suici naguchi returned to

16
00:00:43,910 --> 00:00:41,040
earth completing a successful splashdown

17
00:00:45,750 --> 00:00:43,920
at 2 56 a.m eastern time off the coast

18
00:00:47,670 --> 00:00:45,760
of panama city florida

19
00:00:49,990 --> 00:00:47,680
crew 1 is the first night splashdown of

20
00:00:51,510 --> 00:00:50,000
the u.s spacecraft since apollo 8 in

21
00:00:53,510 --> 00:00:51,520
1968.

22
00:00:55,830 --> 00:00:53,520
this also marks the longest duration

23
00:00:57,189 --> 00:00:55,840
mission of a crude american spacecraft

24
00:00:59,510 --> 00:00:57,199
to date

25
00:01:02,069 --> 00:00:59,520
back in space the crew is keeping busy

26
00:01:04,229 --> 00:01:02,079
with science investigations and studies

27
00:01:06,310 --> 00:01:04,239
aboard the space station

28
00:01:09,030 --> 00:01:06,320
one important investigation includes the

29
00:01:11,190 --> 00:01:09,040
continuing tissue chips in space studies

30
00:01:13,350 --> 00:01:11,200
tissue chips are small models of human

31
00:01:15,510 --> 00:01:13,360
organs containing multiple cell types

32
00:01:17,749 --> 00:01:15,520
which behave similarly as they do in the

33
00:01:19,990 --> 00:01:17,759
body these chips make it possible to

34
00:01:22,550 --> 00:01:20,000
identify safe and effective therapies

35
00:01:24,710 --> 00:01:22,560
like drugs or vaccines much more quickly

36
00:01:26,630 --> 00:01:24,720
than on earth the changes that occur in

37
00:01:28,870 --> 00:01:26,640
the human body during space flight

38
00:01:31,190 --> 00:01:28,880
resemble the onset and progression of

39
00:01:33,749 --> 00:01:31,200
aging and diseases on earth but happen

40
00:01:35,910 --> 00:01:33,759
more quickly in microgravity scientists

41
00:01:38,390 --> 00:01:35,920
can study tissue chips in space to model

42
00:01:41,109 --> 00:01:38,400
diseases that may take months or years

43
00:01:43,590 --> 00:01:41,119
to develop on earth but the science

44
00:01:45,670 --> 00:01:43,600
doesn't stop there this week nasa

45
00:01:48,469 --> 00:01:45,680
astronaut shane kimbrough utilized

46
00:01:50,950 --> 00:01:48,479
astrobee robotics to conduct research

47
00:01:53,670 --> 00:01:50,960
related to space debris

48
00:01:56,069 --> 00:01:53,680
the experiment named relative operations

49
00:01:58,149 --> 00:01:56,079
for autonomous maneuvers or rome

50
00:02:01,030 --> 00:01:58,159
demonstrates processes for a robotic

51
00:02:02,950 --> 00:02:01,040
craft to rendezvous with debris in space

52
00:02:04,789 --> 00:02:02,960
space debris can include objects like

53
00:02:07,190 --> 00:02:04,799
satellites that could be repaired or

54
00:02:09,190 --> 00:02:07,200
taken out of orbit however because many

55
00:02:11,510 --> 00:02:09,200
of these objects are tumbling it makes

56
00:02:13,990 --> 00:02:11,520
rendezvous and docking challenging rome

57
00:02:16,070 --> 00:02:14,000
uses the space station's astro b robots

58
00:02:18,309 --> 00:02:16,080
to observe and understand how targets

59
00:02:20,710 --> 00:02:18,319
tumble and uses this information to plan

60
00:02:22,550 --> 00:02:20,720
ways to safely reach them this research

61
00:02:24,470 --> 00:02:22,560
could help address how space debris

62
00:02:26,790 --> 00:02:24,480
decreases the availability of safe

63
00:02:29,030 --> 00:02:26,800
orbits for satellites including those

64
00:02:32,070 --> 00:02:29,040
critical for weather observation climate

65
00:02:34,470 --> 00:02:32,080
monitoring and communications on earth

66
00:02:36,150 --> 00:02:34,480
and that's space to ground for this week

67
00:02:37,400 --> 00:02:36,160
thanks for watching we'll see you next
