1
00:00:08,360 --> 00:00:05,990
the journey to Mars and back will be a

2
00:00:10,160 --> 00:00:08,370
long way up to three years in an

3
00:00:12,140 --> 00:00:10,170
enclosed space with a small group of

4
00:00:14,060 --> 00:00:12,150
people this mission stands to be more

5
00:00:14,600 --> 00:00:14,070
stressful than any that have come before

6
00:00:16,670 --> 00:00:14,610
it

7
00:00:18,170 --> 00:00:16,680
astronauts will be isolated and confined

8
00:00:19,970 --> 00:00:18,180
for long periods of time

9
00:00:21,859 --> 00:00:19,980
they'll have to conduct critical tasks

10
00:00:24,259 --> 00:00:21,869
under tight deadlines far from home

11
00:00:25,910 --> 00:00:24,269
separated from family and loved ones all

12
00:00:27,259 --> 00:00:25,920
this combined with living in a

13
00:00:28,970 --> 00:00:27,269
weightless environment it all

14
00:00:31,099 --> 00:00:28,980
contributes to physical and

15
00:00:33,500 --> 00:00:31,109
psychological stresses that we'll need

16
00:00:35,420 --> 00:00:33,510
to be prepared for the time and stress

17
00:00:38,090 --> 00:00:35,430
of the mission could lead to changes in

18
00:00:40,130 --> 00:00:38,100
sleep patterns depression fatigue a lack

19
00:00:42,350 --> 00:00:40,140
of motivation irritability and could

20
00:00:44,690 --> 00:00:42,360
even cause prolonged conflict among your

21
00:00:47,330 --> 00:00:44,700
crew if this happens the team could

22
00:00:50,479 --> 00:00:47,340
breakdown possibly even jeopardizing the

23
00:00:52,610 --> 00:00:50,489
mission but we're working on it today

24
00:00:54,680 --> 00:00:52,620
aboard the International Space Station

25
00:00:56,479 --> 00:00:54,690
we're testing new technologies that

26
00:00:58,670 --> 00:00:56,489
could help regulate sleep patterns and

27
00:01:01,130 --> 00:00:58,680
combat fatigue we're learning more about

28
00:01:02,959 --> 00:01:01,140
how isolated crews perform and interact

29
00:01:04,910 --> 00:01:02,969
and how the brain responds to the

30
00:01:07,640 --> 00:01:04,920
stresses of prolonged space flight we're

31
00:01:09,260 --> 00:01:07,650
going to Mars it won't be easy but

32
00:01:11,570 --> 00:01:09,270
because of the research we're doing

33
00:01:13,340 --> 00:01:11,580
today on the ground and aboard the

34
00:01:14,350 --> 00:01:13,350
International Space Station we'll be
