1
00:00:00,760 --> 00:00:03,429
There is a lot of science going on onboard
the International Space Station right now,

2
00:00:03,429 --> 00:00:08,800
and a lot of has to do with just how long
humans survive in space with the eye towards

3
00:00:08,800 --> 00:00:10,170
an eventual mission to Mars.

4
00:00:10,170 --> 00:00:16,850
So the ISS is a scientific platform that allows
for many different kinds of research; it’s

5
00:00:16,850 --> 00:00:17,850
multidisciplinary.

6
00:00:17,850 --> 00:00:23,800
So we do research in the biological sciences,
the physical sciences, Earth and space science,

7
00:00:23,800 --> 00:00:28,660
but because of the presence of human beings
– astronauts, crew members – we are able

8
00:00:28,660 --> 00:00:35,559
to use them as subjects to do human research
and really to learn how the human body adapts

9
00:00:35,559 --> 00:00:40,690
to a microgravity environment over a long
period of time.

10
00:00:40,690 --> 00:00:47,409
What we do in the Program Science Office is
science management; we manage all the research

11
00:00:47,409 --> 00:00:55,120
that’s on board the space station, and specifically
our… one of our main jobs is communicating

12
00:00:55,120 --> 00:01:01,199
the research not just from a US perspective
but across the international partnership.

13
00:01:01,199 --> 00:01:09,020
So the one year mission is really, it is really
about sending humans beyond low Earth orbit,

14
00:01:09,020 --> 00:01:11,890
hopefully to the destination of Mars.

15
00:01:11,890 --> 00:01:16,490
Understanding the effects of long-duration
spaceflight on humans is a huge part of NASA’s

16
00:01:16,490 --> 00:01:17,490
journey to Mars.
