00:00:01,001 --> 00:00:05,004
Four astronauts are launching on NASA's SpaceX Crew-2 mission to the International Space Station

2
00:00:06,005 --> 00:00:10,509
While launch day is a blast, we go to space to do science and research!

3
00:00:10,509 --> 00:00:16,180
That's really the goal of our being up there. We'll be doing hundreds of different science experiments in the six months that we're there.

4
00:00:18,849 --> 00:00:24,020
Astronauts spend their time unlocking discoveries not possible on Earth

5
00:00:25,020 --> 00:00:30,291
Using microgravity to conduct science experiments that will benefit us on the ground

6
00:00:30,291 --> 00:00:40,032
Whether it's biology, material science, fluid mechanics, even medical experiments – we'll do that.

7
00:00:41,533 --> 00:00:45,670
The orbiting laboratory also provides the perfect place to study our Earth

8
00:00:45,670 --> 00:00:51,174
From 250 miles above its surface

9
00:00:51,675 --> 00:00:56,512
Astronauts make critical observations of natural disasters and how human-caused activities change Earth's landscape

10
00:00:56,512 --> 00:01:03,518
Everyday, you do research that you couldn't be doing on the ground because those phenomenas that we're looking at are masked by gravity.

11
00:01:05,019 --> 00:01:09,489
Flying more astronauts to the space station means more time for station science

12
00:01:10,690 --> 00:01:16,361
The research will prepare us for missions further from home, to the Moon and, one day, Mars

13
00:01:16,361 --> 00:01:23,367
We're just going to do a bunch of nice research and science that's going to benefit all of humanity or it's going to help us with future explorations.

14
00:01:23,367 --> 00:01:26,002
So, that's exciting to be a part of something that's that grand.

15
00:01:27,003 --> 00:01:30,005
But it's not just astronauts doing the work

16
00:01:32,007 --> 00:01:37,011
Instruments on the space station study Earth, too

17
00:01:39,012 --> 00:01:43,016
Collecting data on the changing climate, plant life, and natural disasters

18
00:01:45,017 --> 00:01:48,687
The station's 90-minute orbit takes it over 90% of the Earth's population

19
00:01:50,355 --> 00:01:55,359
Giving researchers a unique vantage point for studying our planet
