Propulsion method

Bipropellant Propulsion

A chemical system that burns a separate fuel and oxidiser, releasing far more energy than a monopropellant and delivering higher exhaust velocity. Bipropellant engines — from hypergolic storable combinations to cryogenic hydrogen–oxygen — power launch vehicles, orbit-insertion burns, and deep-space main engines.
