Rockets are powerful machines that can fly all the way into space! They work by burning fuel and shooting hot gases out of the bottom. This pushes the rocket up, up, and away! It is the same idea as when you let go of a balloon and it zooms around the room.
- A rocket has to go at least 17,500 miles per hour to stay in orbit around Earth.
- Most of a rocket’s weight is actually just fuel.
- Some rockets use liquid fuel, and some use solid fuel that burns like a giant firework!
