NASA Kids Science News segment explaining why astronauts float in space.
Hi, I'm Zola with another NASA fact.
00:00:00
Why do astronauts float around in the ISS, our International Space Station?
00:00:06
Because there isn't any gravity up there?
00:00:11
No. Gravity at the ISS is still nine-tenths what it is on Earth.
00:00:13
Then how do astronauts in space float and feel weightless?
00:00:18
The Earth's mass is about a trillion billion elephants.
00:00:21
That pulls you downward, and that's gravity.
00:00:24
You feel weight when the floor pushes up on you to keep you from falling downward toward the Earth's center.
00:00:27
How do you feel when you're in an elevator that starts going down really fast?
00:00:32
Almost like I weigh less for a new suit.
00:00:36
Exactly. Because both you and the elevator are falling.
00:00:38
Are astronauts in the ISS falling?
00:00:42
Yes. As astronauts in the ISS circle the Earth, they are falling freely toward the Earth and feel almost weightless.
