Galileo Jupiter Orbiter propulsion module
NASA's Galileo spacecraft propulsion module was an integrated hypergolic system with twelve 10 N thrusters and one 400 N engine. It used monomethylhydrazine fuel and nitrogen tetroxide oxidizer; the thrusters and main engine supported spacecraft attitude, trajectory, and orbital maneuvers. NASA identifies Messerschmitt-Bolkow-Blohm as the developer and builder and the Federal Republic of Germany as provider. This record represents the complete installed orbiter propulsion module and does not create separate component identities.
