NEAR Shoemaker dual-mode hydrazine/NTO propulsion subsystem
The NEAR Shoemaker dual-mode propulsion subsystem combined one 450 N hydrazine and nitrogen-tetroxide bipropellant thruster for large maneuvers with four 21 N and seven 3.5 N hydrazine thrusters for fine velocity control and momentum dumping. The thruster complement also supported spacecraft attitude control.

- Note
- NASA Planetary Data System NEAR OVERVIEW identifies a dual-mode hydrazine propulsion subsystem with one 450 N bipropellant thruster for large maneuvers, four 21 N thrusters, and seven 3.5 N thrusters for fine velocity control and momentum dumping. It also states that hydrazine is used as fuel for both the monopropellant and bipropellant systems.
