Hi, I'm Emily Martin with more science news you can use

00:00:06,300 --> 00:00:09,240
How many satellites does NASA use to study Earth?

3
00:00:12,280 --> 00:00:17,800
No, NASA uses about 20 satellites. Well, that is still a lot of satellites

4
00:00:17,840 --> 00:00:23,580
Why do we need so many NASA can't study the whole earth. It's just a few satellites

5
00:00:24,060 --> 00:00:26,960
Different satellites can look at lots of different things

6
00:00:27,060 --> 00:00:34,280
What are some of the things that I like to look at some satellites study clouds or lightning while others study is in our rainfall

7
00:00:34,420 --> 00:00:39,580
Some can study volcanoes erupting while others can see how all things grow

8
00:00:39,700 --> 00:00:42,100
Can we see these satellites in orbit?

9
00:00:42,220 --> 00:00:42,720
Sure

10
00:00:42,720 --> 00:00:49,380
They look like a bright dot in the night sky that moves in a straight line check out our website for more about satellites

00:00:49,380 --> 00:00:54,200
