Rocket Engine, Liquid Fuel, Auxiliary Propulsion System (APS), Thruster, Saturn

     

This is an attitude control motor, or APS (Auxiliary Propulsion System), for the S-IVB (third stage) of the Saturn V launch vehicle which took men to the Moon in Project Apollo. APS motors provided three axis control of roll, pitch and yaw control for the S-IV during Earth orbit and injection into lunar orbit. They produced 150 pounds of thrust.

APS engines were used in all the Apollo Saturn V flights from 1967 to 1972. This particular motor has been fired in combustion tests. It was transferred to the NASM in 1974 by the McDonnell-Douglas Astronautics Co.
