Arcjet Propulsion

Arcjet propulsion is a type of thruster that uses electrically heated, high-velocity gases to generate thrust for spacecraft. It works by passing a gas—like nitrogen or ammonia—through an electrical arc, which rapidly heats and accelerates the gas molecules. As these high-speed particles exit the nozzle, they produce a controlled push that propels the spacecraft forward. Arcjet thrusters are efficient for providing steady, moderate propulsion and are especially useful for station-keeping, orbit adjustments, or deep-space missions where precise, reliable thrust is needed.
