Multistage Rocket

We just learned about a rocket's Lift.

Another part of rocket science is Multi Stage Rockets.

Sometimes when rockets are going to go into outer space, the rocket is split up into a few different parts that go off at different times.

The first part of the rocket burns up all of its fuel, then splits off and falls to the ground.
When it does this, the rest of the rocket is lighter, and it starts up another rocket engine that burns and thrusts it up higher.
Each one of these parts is called a stage.
These rockets can have anywhere from 2 to 5 stages, sometimes using different types of fuel, like liquid or solid or gas.
