Mars Global Surveyor twelve 4.45 N hydrazine reaction thrusters

Mars Global Surveyor used four reaction-engine modules containing three 4.45 N hydrazine thrusters each. The thruster complement supported smaller trajectory corrections, attitude control during main-engine burns, roll control, and momentum management.
