Hi, I'm R.J. Brown with more science news you can use.

2
00:00:07,000 --> 00:00:09,000
How does NASA study Earth from space?

3
00:00:09,000 --> 00:00:11,000
With satellites?

4
00:00:11,000 --> 00:00:15,000
You're so smart. Satellites see Earth in ways our eyes can't.

5
00:00:16,000 --> 00:00:18,000
How can satellites do that?

6
00:00:18,000 --> 00:00:21,000
The Aqua satellite sees how much heat comes from the Earth's surface.

7
00:00:21,000 --> 00:00:24,000
This can tell us the ocean's temperature.

8
00:00:24,000 --> 00:00:27,000
What about other satellites?

9
00:00:27,000 --> 00:00:31,000
The Terra satellite watches sand from African dust storms moving across the ocean.

10
00:00:31,000 --> 00:00:33,000
How does it do that?

11
00:00:33,000 --> 00:00:37,000
The Terra satellite measures how much sunlight reflects off the dust particles.

12
00:00:37,000 --> 00:00:40,000
This sand can affect sea life and coral reefs.

13
00:00:40,000 --> 00:00:45,000
I'm glad scientists can use NASA satellites to help us understand how the Earth works.

14
00:00:45,000 --> 00:00:48,000
You can check out our website for more about satellites.

15
00:00:48,000 --> 00:00:53,000
Until next time, I'm R.J. with more cool science news you can use.
