00:00:10,777 --> 00:00:11,478
>> IN THE FUTURE,

2
00:00:11,478 --> 00:00:13,079
WHEN ASTRONAUTS LAND ON MARS,

3
00:00:13,079 --> 00:00:13,747
IT WILL BE THANKS TO

4
00:00:13,747 --> 00:00:15,081
SOME IMPORTANT LESSONS THAT

5
00:00:15,081 --> 00:00:16,483
WE LEARNED ON THE INTERNATIONAL

6
00:00:16,483 --> 00:00:18,084
SPACE STATION.

7
00:00:18,084 --> 00:00:20,387
REWIND.

8
00:00:23,957 --> 00:00:25,859
240 MILES ABOVE THE EARTH,

9
00:00:25,859 --> 00:00:27,026
THE INTERNATIONAL SPACE STATION

10
00:00:27,026 --> 00:00:27,794
IS WHERE WE CURRENTLY

11
00:00:27,794 --> 00:00:29,929
LIVE AND WORK IN SPACE.

12
00:00:29,929 --> 00:00:30,630
HERE'S WHAT WE'VE LEARNED

13
00:00:30,630 --> 00:00:31,898
SO FAR.

14
00:00:31,898 --> 00:00:33,867
FIRST, THERE'S TAKING CARE OF

15
00:00:33,867 --> 00:00:35,435
OUR ASTRONAUTS.

16
00:00:35,435 --> 00:00:36,469
PROLONGED WEIGHTLESSNESS CAN

17
00:00:36,469 --> 00:00:38,238
LEAD TO MUSCLE AND BONE LOSS,

18
00:00:38,238 --> 00:00:39,806
VISION CHANGES, BALANCE

19
00:00:39,806 --> 00:00:41,808
AND COORDINATION LOSS.

20
00:00:41,808 --> 00:00:43,076
THANKS TO THE SPACE STATION,

21
00:00:43,076 --> 00:00:44,344
COUNTERMEASURES ARE BEING

22
00:00:44,344 --> 00:00:45,278
DEVELOPED TO KEEP

23
00:00:45,278 --> 00:00:46,446
ASTRONAUTS HEALTHY FOR

24
00:00:46,446 --> 00:00:49,416
LONG DURATION MISSIONS.

25
00:00:49,416 --> 00:00:51,017
THEN THERE'S THE EQUIPMENT--

26
00:00:51,017 --> 00:00:52,685
SPACECRAFT COMMUNICATION,

27
00:00:52,685 --> 00:00:53,787
WATER RECYCLING,

28
00:00:53,787 --> 00:00:55,121
AIR AND POWER PRODUCTION

29
00:00:55,121 --> 00:00:56,623
ARE ALL BEING TEST DRIVEN ON

30
00:00:56,623 --> 00:00:58,625
THE INTERNATIONAL SPACE STATION.

31
00:00:58,625 --> 00:00:59,492
WHAT WE LEARN ABOUT

32
00:00:59,492 --> 00:01:00,794
OPERATING AND MAINTAINING

33
00:01:00,794 --> 00:01:01,961
OUR GEAR IN THE HARSHNESS

34
00:01:01,961 --> 00:01:03,830
OF SPACE WILL PAVE THE WAY

35
00:01:03,830 --> 00:01:05,064
FOR FUTURE MISSIONS

36
00:01:05,064 --> 00:01:07,300
INTO OUR SOLAR SYSTEM.

37
00:01:07,300 --> 00:01:08,635
AND THAT'S HOW THE SPACE

38
00:01:08,635 --> 00:01:10,136
STATION IS HELPING US EXTEND

39
00:01:10,136 --> 00:01:12,806
HUMAN PRESENCE INTO DEEP SPACE.
