Scientists develop a greener, catalyst-free, rocket thruster to power the next generation of spacecraft

An experimental green rocket thruster successfully ignited at room temperature using electricity instead of a preheated catalyst. The system passed current directly through an ammonium dinitramide fuel, while an electric arc helped reduce unstable pressure swings. The design avoids long catalyst preheating, but high electrical demand and combustion instability remain major challenges. An experimental “green” rocket thruster has fired successfull…
