Earth orbit rendezvous ( EOR ) is a method for conducting round trip human flights to the Moon, involving the use of space rendezvous to assemble, and possibly fuel, components of a translunar vehicle in low Earth orbit . It was considered as an alternative to direct ascent but ultimately rejected in favor of lunar orbit rendezvous (LOR) for NASA 's Apollo program of the 1960s and 1970s, mainly because LOR does not require a spacecraft big enough to both make the return trip from Earth orbit to splash down in the ocean, and a soft landing on the lunar surface. The two main proposed methodologies were: the in-space assembly of fueled spacecraft modules via docking techniques; and the in-space refueling of fully assembled spacecraft. This was the preferred approach adopted by the Soviet Union for achieving human lunar missions.

Experiments of Project Gemini involving docking with the Agena target vehicle were designed partly to test the feasibility of this program. In the end, NASA employed the Lunar Orbit Rendezvous for the Apollo Program : a Saturn V would simultaneously lift both the Apollo Command and Lunar Modules into low Earth orbit, and then

The Agena-Gemini rendezvous also achieved other objectives in later Gemini launches, including docked orbital maneuvering ( Gemini 10 and Gemini 11 ), inspection of the abandoned Gemini 8 ATV (Gemini 10) and space walks ( Gemini 12 ). 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
49-607: The Saturn V third stage would fire again ( Trans-lunar injection ) to send both spacecraft to the Moon. This mode had been revived for Project Constellation as the Earth Departure Stage (EDS) and Altair (LSAM), which would be launched into low Earth orbit on the Ares V rocket. The EDS and Altair would be met by the separately launched Orion (CEV). Once joined in low Earth orbit, the three would then travel out to
