Project Orion was a study to design a starship that would use nuclear pulse propulsion to propel itself through space. The idea was to detonate a series of atomic bombs behind the spacecraft, which would eject a portion of the reaction mass at high velocity into a pusher plate at the back of the ship. The interaction between the blast wave and the plate would transfer momentum to the ship, propelling it forward. #space #science #physics #astronomy #nasa #projectorion #spacescience | Space Scienc
