houston station on space to ground

2
00:00:08,470 --> 00:00:06,480
welcome to space to grounds i'm chelsea

3
00:00:10,390 --> 00:00:08,480
bayarte did you know that a third of

4
00:00:12,950 --> 00:00:10,400
american astronauts experience vision

5
00:00:14,629 --> 00:00:12,960
changes in space that number may be even

6
00:00:16,470 --> 00:00:14,639
bigger for astronauts on long-duration

7
00:00:18,310 --> 00:00:16,480
missions the astronauts aboard the

8
00:00:20,550 --> 00:00:18,320
station are getting eye exams this week

9
00:00:22,630 --> 00:00:20,560
to help researchers understand why so

10
00:00:24,790 --> 00:00:22,640
what else is on the to-do list this week

11
00:00:26,470 --> 00:00:24,800
tasks include space plumbing and looking

12
00:00:27,990 --> 00:00:26,480
out the window

13
00:00:30,150 --> 00:00:28,000
if your eyes are getting a little puffy

14
00:00:31,910 --> 00:00:30,160
this time of year that may be because of

15
00:00:33,990 --> 00:00:31,920
allergies but if you've seen an

16
00:00:35,830 --> 00:00:34,000
astronaut with a puffy face that could

17
00:00:37,750 --> 00:00:35,840
be because gravity is not there to pull

18
00:00:39,510 --> 00:00:37,760
down their body's fluids vision

19
00:00:41,430 --> 00:00:39,520
researchers have created an imaging

20
00:00:44,150 --> 00:00:41,440
technique used on the space station

21
00:00:45,750 --> 00:00:44,160
called optical coherence tomography it's

22
00:00:47,750 --> 00:00:45,760
basically a way to take a picture of the

23
00:00:49,510 --> 00:00:47,760
back of the eye and the astronauts on

24
00:00:51,510 --> 00:00:49,520
board are using it to examine their eyes

25
00:00:53,430 --> 00:00:51,520
this week this data is important to

26
00:00:55,189 --> 00:00:53,440
understand as nasa prepares for

27
00:00:56,709 --> 00:00:55,199
long-duration space flights to the moon

28
00:01:00,150 --> 00:00:56,719
and one day onto mars through nasa's

29
00:01:02,389 --> 00:01:00,160
artemis program nasa has selected axiom

30
00:01:04,149 --> 00:01:02,399
space and collins aerospace to develop

31
00:01:06,230 --> 00:01:04,159
the next generation of spacesuits to

32
00:01:07,910 --> 00:01:06,240
advance spacewalking capabilities to

33
00:01:09,990 --> 00:01:07,920
astronauts stepping outside of the space

34
00:01:11,830 --> 00:01:10,000
station and one day the moon these

35
00:01:14,070 --> 00:01:11,840
spacesuits build on the success of

36
00:01:15,990 --> 00:01:14,080
previous suits by increasing mobility

37
00:01:17,910 --> 00:01:16,000
new technologies and advanced life

38
00:01:19,590 --> 00:01:17,920
support capabilities the suits will

39
00:01:21,030 --> 00:01:19,600
arrive aboard the space station after

40
00:01:23,590 --> 00:01:21,040
they complete all of the necessary

41
00:01:26,710 --> 00:01:23,600
environmental testing here on earth

42
00:01:28,630 --> 00:01:26,720
to quote russian cosmonaut oleg artemyev

43
00:01:30,149 --> 00:01:28,640
there's no sweeter sound on the space

44
00:01:31,350 --> 00:01:30,159
station than the sound of a working

45
00:01:33,270 --> 00:01:31,360
toilet

46
00:01:35,350 --> 00:01:33,280
nasa astronaut jessica watkins took to

47
00:01:37,109 --> 00:01:35,360
twitter to talk about space plumbing

48
00:01:39,190 --> 00:01:37,119
explaining that each member of the crew

49
00:01:40,870 --> 00:01:39,200
brings unique skill sets to the table

50
00:01:43,270 --> 00:01:40,880
and sometimes that includes fixing

51
00:01:45,350 --> 00:01:43,280
toilets and space watkins is brand new

52
00:01:47,510 --> 00:01:45,360
to the twitterverse so give at astro

53
00:01:49,190 --> 00:01:47,520
underscore watkins a follow

54
00:01:51,109 --> 00:01:49,200
speaking of tweets from space nasa

55
00:01:52,870 --> 00:01:51,119
astronaut bob hines shared these photos

56
00:01:54,870 --> 00:01:52,880
while looking at our earth from 250

57
00:01:56,630 --> 00:01:54,880
miles above he used his aerospace

58
00:01:58,550 --> 00:01:56,640
engineering background to explain that

59
00:02:00,789 --> 00:01:58,560
as the wind blows past the mountains the

60
00:02:02,630 --> 00:02:00,799
viscosity of the air causes eddies or

61
00:02:04,149 --> 00:02:02,640
vortices to be shed from alternating

62
00:02:06,149 --> 00:02:04,159
sides of the mountain it's the same

63
00:02:07,670 --> 00:02:06,159
phenomena that makes a flag wave

64
00:02:09,350 --> 00:02:07,680
bob hines may have been looking down at

65
00:02:10,710 --> 00:02:09,360
the earth for those photos but did you

66
00:02:12,229 --> 00:02:10,720
know that you can look up and see the

67
00:02:14,949 --> 00:02:12,239
space station as it flies above your

68
00:02:16,790 --> 00:02:14,959
hometown go to spottystation.gov to find

69
00:02:18,550 --> 00:02:16,800
out what time to look up and if you

70
00:02:20,790 --> 00:02:18,560
capture any photos share them with us

71
00:02:22,229 --> 00:02:20,800
using spot the station

72
00:02:23,589 --> 00:02:22,239
that's space to ground for this week

73
00:02:34,920 --> 00:02:23,599
thanks for watching we'll see you next
