There's a rocket attached to a shuttle (the shuttle looks like a plane).

The rocket is used to get the shuttle (where the astronauts are) into space with a lot of power. 

After it get's high enough the rocket deattaches from the shuttle and the shuttle enters space. 

To come back: the shuttle reenters the eath's atmosphere and lands like a regular airplane.
They go through rockets and come back in rockets
