NASA New Research October Mission Completed

Video Subtitles
1
00:00:05,089 --> 00:00:06,369
WELCOME TO SPACE TO GROUND.

2
00:00:06,369 --> 00:00:07,870
I AM KAYLA LAFRANCE.

3
00:00:07,870 --> 00:00:11,580
WITH THEIR SPACE LEGS NOW UNDER THEM, THE
EXPEDITION 70 CREW

4
00:00:11,580 --> 00:00:16,119
IS CURRENTLY PREPARING FOR A PAIR OF SPACE
WALKS THIS MONTH.

5
00:00:16,119 --> 00:00:21,230
ON OCTOBER 12TH, NASA ASTRONAUT LORAL O’HARA
AND ESA ASTRONAUT ANDY MOGENSEN

6
00:00:21,230 --> 00:00:24,359
WILL TEAM UP AND EXIT THROUGH THE STATION’S
QUEST AIRLOCK,

7
00:00:24,359 --> 00:00:27,400
WHERE THEY WILL REPLACE A HIGH-DEFINITION
CAMERA

8
00:00:27,400 --> 00:00:31,230
ON THE PORT TRUSS OF THE STATION AND CONDUCT
OTHER MAINTENANCE WORK

9
00:00:31,230 --> 00:00:33,489
TO PREPARE FOR FUTURE SPACEWALKS

10
00:00:33,489 --> 00:00:37,190
TO UPGRADE THE STATION’S ALPHA MAGNETIC
SPECTROMETER.

11
00:00:37,190 --> 00:00:38,710
ALSO PLANNED FOR THIS EVA,

12
00:00:38,710 --> 00:00:43,149
IS AN EXPERIMENT WHERE THE ORBITING LABORATORY
ITSELF IS THE SUBJECT.

13
00:00:43,149 --> 00:00:46,359
THE SPACEWALKERS WILL TRAVERSE THE EXTERIOR
OF THE STATION

14
00:00:46,359 --> 00:00:49,310
TO COLLECT SAMPLES ON THE SURFACE OF THE MODULES.

15
00:00:49,310 --> 00:00:52,309
THESE SAMPLES WILL BE RETURNED TO THE GROUND
FOR ANALYSIS

16
00:00:52,309 --> 00:00:57,090
TO SEE IF MICROORGANISMS ARE RELEASED AND
SURVIVE OUTSIDE OF STATION.

17
00:00:57,090 --> 00:01:02,429
MICROORGANISMS LIKE BACTERIA AND FUNGI LIVE
ON AND AROUND HUMANS,

18
00:01:02,429 --> 00:01:05,300
AND BEFORE EXPLORERS SEARCH FOR LIFE ELSEWHERE,

19
00:01:05,300 --> 00:01:09,110
INVESTIGATORS LOOK TO IDENTIFY THE MICROORGANISMS
THAT MAY BE

20
00:01:09,110 --> 00:01:12,320
TRANSPORTED WITH CREW MEMBERS INTO SPACE.

21
00:01:12,320 --> 00:01:15,970
THE SAMPLES WILL BE TAKEN NEAR LIFE SUPPORT
SYSTEM VENTS,

22
00:01:15,970 --> 00:01:19,810
TO EXAMINE WHETHER THE SPACECRAFT RELEASES
MICROORGANISMS,

23
00:01:19,810 --> 00:01:22,820
HOW MANY, AND HOW FAR THEY MAY HAVE TRAVELED.

24
00:01:22,820 --> 00:01:24,890
THIS RESEARCH COULD HELP DETERMINE WHETHER

25
00:01:24,890 --> 00:01:29,360
CHANGES ARE NEEDED TO CREWED SPACECRAFT, INCLUDING
SPACESUITS,

26
00:01:29,360 --> 00:01:35,549
USED TO EXPLORE DESTINATIONS WHERE LIFE MAY
EXIST NOW OR EXISTED PREVIOUSLY,

27
00:01:35,549 --> 00:01:38,130
AND TO LIMIT THE SPREAD OF HUMAN CONTAMINATION

28
00:01:38,130 --> 00:01:42,770
AS WE MOVE BEYOND LOW EARTH ORBIT AND ON TO
MARS.

29
00:01:42,770 --> 00:01:45,799
ON OCTOBER 20TH, LORAL O’HARA WILL ONCE
AGAIN

30
00:01:45,799 --> 00:01:48,049
VENTURE OUTSIDE OF THE SPACE STATION,

31
00:01:48,049 --> 00:01:51,681
THIS TIME SHE WILL BE ACCOMPANIED BY NASA
ASTRONAUTS JASMIN MOGHBELI.

32
00:01:51,681 --> 00:01:55,689
THE DYNAMIC DUO WILL WORK TOGETHER TO COMPLETE
THE REMOVAL

33
00:01:55,689 --> 00:01:59,350
OF A FAULTY ELECTRONICS BOX, CALLED A RADIO
FREQUENCY GROUP

34
00:01:59,350 --> 00:02:03,719
FROM A COMMUNICATIONS ANTENNA ON THE STARBOARD
TRUSS OF THE STATION.

35
00:02:03,719 --> 00:02:07,630
THEY WILL ALSO REPLACE ONE OF TWELVE TRUNDLE
BEARING ASSEMBLIES

36
00:02:07,630 --> 00:02:10,459
ON THE PORT TRUSS SOLAR ALPHA ROTARY JOINT

37
00:02:10,459 --> 00:02:14,490
THAT STALLED RECENTLY BEFORE RESUMING ITS
NORMAL OPERATION.

38
00:02:14,490 --> 00:02:17,080
THE TBAS ENABLE THE STATION’S SOLAR ARRAYS

39
00:02:17,080 --> 00:02:21,910
TO ROTATE PROPERLY TO TRACK THE SUN AS THE
STATION ORBITS THE EARTH.

40
00:02:21,910 --> 00:02:25,610
THIS WILL BE JASMIN’S FIRST SPACEWALK AND
THE SECOND FOR LORAL.

41
00:02:25,610 --> 00:02:29,790
AS ALWAYS, LIVE COVERAGE WILL BE PROVIDED
FOR BOTH SPACEWALKS,

42
00:02:29,790 --> 00:02:33,560
SO FOLLOW US ON SOCIAL MEDIA, OR WATCH IT
ON NASA TELEVISION,

43
00:02:33,560 --> 00:02:36,750
THE NASA APP, OR THE AGENCY’S WEBSITE.

44
00:02:36,750 --> 00:02:38,760
YOU WON’T WANT TO MISS IT.

45
00:02:38,760 --> 00:02:40,450
AND THAT’S SPACE TO GROUND FOR THIS WEEK.

46
00:02:40,450 --> 00:02:41,450
THANKS FOR WATCHING.

47
00:02:41,450 --> 00:02:42,489
WE’LL SEE YOU NEXT WEEK!
