General Galactic to Test Water-Only Propulsion on Falcon 9 Demonstration
A US startup, General Galactic, will attempt an orbital test of a satellite using water as its only propellant, riding a Falcon 9 later this fall. The mission will trial both electrolysis-driven chemical burns and a water-fed Hall-effect electric thruster, a dual approach that, if successful, could reshape satellite refueling and maneuverability strategies.
