> Apollo missions used two launches of the Saturn V - one for the crew capsule and one for the lunar lander, which rendezvoused in orbit. That was a concept called "Earth Orbit Rendezvous" which was discarded early on during the Apollo program in favor of "Lunar Orbit Rendezvous" where the Command and Service Module (CSM) and the Lunar Module (LM) was launched on a single Saturn V. You can see this in the movie Apollo 13.
