00:00:09,589 --> 00:00:06,960
welcome to space to ground i'm sandra

00:00:11,430 --> 00:00:09,599
jones with crew 3 now safely back on

00:00:13,589 --> 00:00:11,440
earth following their six-month mission

5
00:00:15,430 --> 00:00:13,599
to the international space station

6
00:00:17,590 --> 00:00:15,440
science continues aboard the orbital

7
00:00:19,269 --> 00:00:17,600
laboratory and preps are underway for a

8
00:00:20,550 --> 00:00:19,279
new vehicle to arrive to the space

9
00:00:23,109 --> 00:00:20,560
station

10
00:00:25,509 --> 00:00:23,119
crew 3 which includes nasa astronauts

11
00:00:27,509 --> 00:00:25,519
raja chari tom marshburn kayla barron

12
00:00:29,509 --> 00:00:27,519
and european space agency astronaut

13
00:00:31,669 --> 00:00:29,519
matthias maurer splash down off the

14
00:00:34,069 --> 00:00:31,679
coast of tampa florida in the wee hours

15
00:00:35,990 --> 00:00:34,079
on may 6th wrapping up their mission and

16
00:00:36,790 --> 00:00:36,000
bringing science samples back to planet

17
00:00:38,790 --> 00:00:36,800
earth

18
00:00:40,630 --> 00:00:38,800
riding alongside the astronauts were

19
00:00:42,069 --> 00:00:40,640
samples from the space biofilms

20
00:00:44,310 --> 00:00:42,079
investigation

21
00:00:46,869 --> 00:00:44,320
microbes can join to form what is called

22
00:00:48,630 --> 00:00:46,879
biofilm which can form on surfaces and

23
00:00:50,950 --> 00:00:48,640
cause issues with equipment like

24
00:00:52,869 --> 00:00:50,960
spacesuits and water recycling units

25
00:00:54,630 --> 00:00:52,879
they can also increase the risk of human

26
00:00:56,389 --> 00:00:54,640
illnesses so we need to better

27
00:00:59,110 --> 00:00:56,399
understand them to enable safe

28
00:01:01,270 --> 00:00:59,120
long-duration human space exploration

29
00:01:03,590 --> 00:01:01,280
astronauts grew biofilms on surface

30
00:01:06,070 --> 00:01:03,600
samples like stainless steel a titanium

31
00:01:08,230 --> 00:01:06,080
alloy silicon as well as a surface that

32
00:01:10,149 --> 00:01:08,240
was treated with a new lubricant to see

33
00:01:13,109 --> 00:01:10,159
if it affects the formation or growth of

34
00:01:15,190 --> 00:01:13,119
biomolds biofilm formation also poses a

35
00:01:16,870 --> 00:01:15,200
health hazard on earth what we learned

36
00:01:18,630 --> 00:01:16,880
from this experiment could also have

37
00:01:20,550 --> 00:01:18,640
applications for protecting the health

38
00:01:23,109 --> 00:01:20,560
of people on the ground

39
00:01:25,109 --> 00:01:23,119
crew 3 participated in hundreds of other

40
00:01:26,950 --> 00:01:25,119
science investigations and technology

41
00:01:29,190 --> 00:01:26,960
demonstrations during their mission

42
00:01:31,190 --> 00:01:29,200
including five independent plant growth

43
00:01:33,030 --> 00:01:31,200
experiments and a first of its kind

44
00:01:35,429 --> 00:01:33,040
archaeological study of the space

45
00:01:37,350 --> 00:01:35,439
station this valuable research will help

46
00:01:39,510 --> 00:01:37,360
to prepare humans for future space

47
00:01:41,590 --> 00:01:39,520
exploration missions while generating

48
00:01:43,109 --> 00:01:41,600
innovations and benefits for humanity

49
00:01:45,190 --> 00:01:43,119
here on earth

50
00:01:47,749 --> 00:01:45,200
coming soon to the international space

51
00:01:49,109 --> 00:01:47,759
station boeing's operational flight test

52
00:01:50,870 --> 00:01:49,119
2.

53
00:01:53,030 --> 00:01:50,880
earlier this week the nasa and boeing

54
00:01:55,749 --> 00:01:53,040
team participated in a flight readiness

55
00:01:57,429 --> 00:01:55,759
review ahead of boeing's oft2 test

56
00:01:59,429 --> 00:01:57,439
flight which is slated to launch from

57
00:02:01,270 --> 00:01:59,439
the kennedy space center in florida no

58
00:02:03,030 --> 00:02:01,280
earlier than may 19th

59
00:02:05,030 --> 00:02:03,040
you can hear more about this test flight

60
00:02:07,350 --> 00:02:05,040
on this week's episode of houston we

61
00:02:09,990 --> 00:02:07,360
have a podcast where boeing starliner

62
00:02:11,510 --> 00:02:10,000
project engineer amy como discussed the

63
00:02:14,470 --> 00:02:11,520
mission in detail

64
00:02:18,229 --> 00:02:14,480
check it out on nasa.gov podcasts apple

podcast google podcast and soundcloud

66
00:02:21,830 --> 00:02:20,319
and that's space to ground for this week

67
00:02:22,100 --> 00:02:21,840
thanks for watching we'll see you next

68
00:02:34,229 --> 00:02:22,110
