US-based startup RocketStar has successfully demonstrated an electric propulsion unit for spacecraft that uses nuclear fusion-enhanced pulsed plasma. The company’s the FireStar Drive uses is a water-fueled pulsed plasma thruster that uses a form of aneutronic nuclear fusion to boost its performance. According to Rocketstart, its propulsion system’s base thruster generates high speed protons through the ionization of water vapor. When these protons collide with the nucleus of a boron atom, the at...
