Lucy spacecraft propulsion subsystem
NASA's Lucy spacecraft has a dual-mode chemical propulsion subsystem: one bipropellant main engine assembly for deep-space maneuvers, six monopropellant trajectory-correction maneuver thrusters, and eight monopropellant attitude-control thrusters. NASA technical material identifies hydrazine monopropellant and hydrazine/nitrogen-tetroxide bipropellant capability. The individual engine and thruster product models are not asserted; this record represents the complete installed spacecraft propulsion subsystem.
