The EOR proposal for Apollo consisted of using a series of small rockets half the size of a [[Saturn V]] to put different components of a spacecraft to go to the Moon in orbit around the Earth, then assemble them in orbit.  Experiments of [[Project Gemini]] involving docking with the [[Agena target vehicle]] were designed partly to test the feasibility of this program.{{citation needed|date=October 2016}}

In the end, NASA employed the [[Lunar Orbit Rendezvous]] for the [[Project Apollo|Apollo Program]]: a  Saturn V would simultaneously lift both the [[Apollo Command Module|Apollo Command]] and [[Apollo Lunar Module|Lunar Modules]] into low Earth orbit, and then the Saturn V third stage would fire again ([[Trans-lunar injection]]) to send both spacecraft to the Moon.<ref>{{cite web
