Pale Blue's Water-Based Propulsion System Proves Successful in Space
Japanese company Pale Blue has successfully tested its water-based propulsion system in orbit for the first time, using a "resistojet" to adjust the orbit of Sony's EYE satellite. Pale Blue is also developing an ion thruster and plans to combine the two systems into a hybrid thruster. The company's innovative use of water as a propellant offers a safe and affordable alternative to traditional propulsion systems for satellite designers.
