Project Orion

Project Orion was the first engineering design study of a spacecraft powered by nuclear pulse propulsion. Orion design would have worked by dropping fission or thermonuclear explosives out the rear of a vehicle, detonating them 200 feet (60 m) out, and catching the blast with a thick steel or aluminum pusher plate.
