How Rocket Engines Work
Space exploration is complicated because there are so many problems to solve and obstacles to overcome. The biggest problem of all is harnessing enough energy simply to get a spaceship off the ground. That is where rocket engines come in.
Rocket engines are, on the one hand, so simple that you can build and fly your own model rockets very inexpensively. Rocket engines are reaction engines. The basic principle driving a rocket engine is the famous Newtonian principle that “to every action there is an equal and opposite reaction.”
