General Galactic is developing water-powered space propulsion systems. The core of this system is electrolyzer, which splits water molecules into hydrogen and oxygen, then converts the oxygen into plasma. The system then uses a magnetic field to extract the plasma from the engine. In the case of chemical propulsion, electrolysis is followed by combustion of hydrogen with oxygen as an oxidizer. Electric propulsion is designed to provide a constant flow of thrust, which could prove effective for reaching deep space targets like Mars. Chemical propulsion, on the other hand, can provide much more powerful but short-lived pulses of thrust, allowing satellites to accelerate in space. General Galactic plans to launch its first 500-kilogram satellite aboard a SpaceX Falcon 9 rocket. In space, the satellite will demonstrate the two types of water engines.
