Propulsion method
Monopropellant Propulsion
A simple chemical system in which a single propellant — classically hydrazine — is decomposed over a catalyst bed to produce hot gas, needing no separate oxidiser or ignition. Monopropellant thrusters are workhorses for spacecraft attitude control and small maneuvers, valued for their simplicity and quick, repeatable pulses.
