John Houbolt, an engineer at Langley Research Center, is credited with fully developing the lunar-orbit rendezvous (LOR) approach. It involved firing three spacecraft (command module, service module, and lunar module) aboard one Saturn V rocket into Earth orbit. Once there, the last stage of the Saturn boosted the spacecraft on a lunar trajectory and eventually into orbit. Only the lunar module would go down to the surface. It would then return and redock with the orbiting command module in the top-half of the lunar module (leaving the lower-half on the moon). The astronauts would return to Earth in the command module while the remainder of the lunar module was ejected into space.
