Rocketry

Like most engines, rockets burn fuel. Typically a rocket engine turns the fuel into hot gas and then pushes that gas out the back, propelling the rocket forward. Unlike jet engines, a rocket engine doesn't need air. That's why it works in space.

Take a look at how rockets have changed since they were invented more than 800 years ago, and how NASA hopes to use rockets in the future.
