houston station on space to ground

00:00:09,430 --> 00:00:06,879
welcome to space to ground i'm sandra

3
00:00:11,270 --> 00:00:09,440
jones this week a million hour science

4
00:00:13,509 --> 00:00:11,280
milestone was reached on board the

5
00:00:15,829 --> 00:00:13,519
international space station and we're

6
00:00:18,310 --> 00:00:15,839
using the flight of the astrobee robots

7
00:00:20,710 --> 00:00:18,320
to troubleshoot potential risk

8
00:00:23,189 --> 00:00:20,720
the international space station is first

9
00:00:25,750 --> 00:00:23,199
and foremost an orbiting laboratory and

10
00:00:28,550 --> 00:00:25,760
has been continuously operated for over

11
00:00:31,189 --> 00:00:28,560
21 years for just that reason

12
00:00:32,950 --> 00:00:31,199
at any given time there are two to 300

13
00:00:35,110 --> 00:00:32,960
science experiments being conducted

14
00:00:37,350 --> 00:00:35,120
aboard the space station we're able to

15
00:00:39,910 --> 00:00:37,360
house and operate so many experiments

16
00:00:41,670 --> 00:00:39,920
largely thanks to 12 modular racks that

17
00:00:44,389 --> 00:00:41,680
provide power and other structures

18
00:00:46,389 --> 00:00:44,399
needed to operate in space that expedite

19
00:00:48,950 --> 00:00:46,399
the processing of experiments to the

20
00:00:51,350 --> 00:00:48,960
space station or express racks system

21
00:00:53,590 --> 00:00:51,360
reached a major milestone of 1 million

22
00:00:54,630 --> 00:00:53,600
hours of cumulative operating time this

23
00:00:55,750 --> 00:00:54,640
week

24
00:00:57,510 --> 00:00:55,760
now to put

25
00:01:00,790 --> 00:00:57,520
a million hours in perspective that's

26
00:01:02,229 --> 00:01:00,800
over 114 years and 114 years ago it's

27
00:01:04,310 --> 00:01:02,239
five years after the wright brothers

28
00:01:05,910 --> 00:01:04,320
first powered flight the birth of the

29
00:01:07,670 --> 00:01:05,920
aerospace industry

30
00:01:08,710 --> 00:01:07,680
this million hour milestone would not

31
00:01:10,870 --> 00:01:08,720
have been possible without the

32
00:01:13,830 --> 00:01:10,880
dedication and vigilance of the crew

33
00:01:15,670 --> 00:01:13,840
flight controllers and engineering teams

34
00:01:17,990 --> 00:01:15,680
what if you could identify the need to

35
00:01:20,469 --> 00:01:18,000
repair a potential problem with plenty

36
00:01:22,310 --> 00:01:20,479
of time to fix it an investigation on

37
00:01:25,590 --> 00:01:22,320
the space station is looking into this

38
00:01:28,070 --> 00:01:25,600
by using robotics and sound

39
00:01:30,550 --> 00:01:28,080
nasa astronaut jessica watkins conducted

40
00:01:32,710 --> 00:01:30,560
operations with the astrobees related to

41
00:01:35,030 --> 00:01:32,720
soundc which monitors the acoustic

42
00:01:37,910 --> 00:01:35,040
environment using an audio sensor on

43
00:01:39,830 --> 00:01:37,920
astrobee the system can detect anomalies

44
00:01:41,990 --> 00:01:39,840
in the sound of components inside a

45
00:01:44,069 --> 00:01:42,000
machine providing autonomous monitoring

46
00:01:46,550 --> 00:01:44,079
of the health of infrastructure such as

47
00:01:48,550 --> 00:01:46,560
life support and exercise equipment on

48
00:01:50,389 --> 00:01:48,560
earth autonomous audio monitoring of the

49
00:01:52,550 --> 00:01:50,399
health of machines could be applied in a

50
00:01:54,870 --> 00:01:52,560
variety of settings such as healthcare

51
00:01:56,950 --> 00:01:54,880
and infrastructure development

52
00:01:59,590 --> 00:01:56,960
for many the accessibility to a health

53
00:02:01,590 --> 00:01:59,600
facility is not a short car drive away

54
00:02:03,749 --> 00:02:01,600
that's true for people living in remote

55
00:02:06,069 --> 00:02:03,759
areas on our planet and for crews aboard

56
00:02:08,150 --> 00:02:06,079
the international space station

57
00:02:10,229 --> 00:02:08,160
a project on the space station called

58
00:02:12,869 --> 00:02:10,239
advanced diagnostic ultrasound in

59
00:02:15,350 --> 00:02:12,879
microgravity was created to see how to

60
00:02:19,030 --> 00:02:15,360
potentially diagnose medical conditions

61
00:02:21,030 --> 00:02:19,040
and injuries in space using ultrasound

62
00:02:23,510 --> 00:02:21,040
we invite you to tune into the latest

63
00:02:25,270 --> 00:02:23,520
episode of houston we have a podcast

64
00:02:27,270 --> 00:02:25,280
where we will be discussing how this

65
00:02:29,830 --> 00:02:27,280
project could not only impact the health

66
00:02:31,910 --> 00:02:29,840
of astronauts during long-duration space

67
00:02:34,949 --> 00:02:31,920
missions in the future but how it

68
00:02:37,030 --> 00:02:34,959
already has impacted people on earth

69
00:02:38,790 --> 00:02:37,040
and that's space to ground for this week

70
00:02:41,120 --> 00:02:38,800
thanks so much for watching we'll see

71
00:02:58,949 --> 00:02:41,130
you next week
