hi i'm scott kelly a member of the

2
00:00:09,669 --> 00:00:06,000
expedition 43 crew on the international

3
00:00:11,589 --> 00:00:09,679
space station flying almost 260 miles

4
00:00:13,509 --> 00:00:11,599
above you

5
00:00:15,910 --> 00:00:13,519
a month ago i left earth for a year in

6
00:00:19,109 --> 00:00:15,920
space longer than any u.s astronaut has

7
00:00:20,870 --> 00:00:19,119
flown in orbit on a single mission

8
00:00:23,189 --> 00:00:20,880
nasa is studying the effects of

9
00:00:25,429 --> 00:00:23,199
long-term exposure to weightlessness and

10
00:00:29,269 --> 00:00:25,439
how this data will pave the way for us

11
00:00:31,429 --> 00:00:29,279
to explore mars in the future

12
00:00:34,310 --> 00:00:31,439
fulfilling my dream of becoming a navy

13
00:00:36,630 --> 00:00:34,320
pilot and ultimately an astronaut

14
00:00:40,869 --> 00:00:36,640
required a tremendous amount of training

15
00:00:42,790 --> 00:00:40,879
in science engineering and math

16
00:00:45,029 --> 00:00:42,800
and i wouldn't be here speaking to you

17
00:00:47,910 --> 00:00:45,039
today from orbit without all the great

18
00:00:50,069 --> 00:00:47,920
teachers who motivated and inspired me

19
00:00:53,189 --> 00:00:50,079
so thank you stem teachers

20
00:00:59,029 --> 00:00:55,590
to all of you students look how cool

21
00:01:02,069 --> 00:00:59,039
math and science can be

22
00:01:04,630 --> 00:01:02,079
as a retired navy captain and a father i

23
00:01:07,429 --> 00:01:04,640
know how important it is that we support

24
00:01:09,830 --> 00:01:07,439
our military connected kids and give

25
00:01:13,830 --> 00:01:09,840
them the tools and resources they

26
00:01:16,310 --> 00:01:13,840
deserve to pursue their dreams

27
00:01:19,429 --> 00:01:16,320
that's why nasa and i are excited to be

28
00:01:21,990 --> 00:01:19,439
part of today's joining forces event to

29
00:01:24,950 --> 00:01:22,000
celebrate the national math and science

30
00:01:28,630 --> 00:01:24,960
initiatives college readiness program

31
00:01:33,910 --> 00:01:31,590
