Apollo 9 SIVB



The Apollo Saturn V SIVB was the third stage of the Saturn V booster. The SIVB consisted of a truncated cone with a bottom diameter of 10.06 m topped by a long cylinder with a diameter of 6.60 m. Total height was 17.80 m. It contained liquid hydrogen and liquid oxygen tanks and a J2 engine. It was launched into Earth orbit attached to the Command, Service, and Lunar Modules (CSM and LM). For lunar missions the SIVB provided the thrust to take the CSM and LM from Earth orbit into a lunar transfer orbit. The CSM and LM on this mission were left in Earth orbit for rendezvous and docking practice. On 3 March 1969 the S-IVB stage made a third burn to put it into a solar orbit.
