Once the S-IVB inserted the spacecraft into a lunar trajectory, it separated from the rest of ­the vehicle. At that point, the spacecraft would jettison the 4,000 pound spacecraft lunar module adapter (SLA). Now, all that remained of the spacecraft was the command module (CM), the service module (SM) and the lunar module (LM).
