|Gemini LORV - Gemini Lunar Orbit Rescue Vehicle, studied for rescue of an Apollo crew stranded in lunar orbit. Gemini would be launched by Saturn V. Following lunar orbit insertion it would rendezvous with the disabled Apollo. The three Apollo crew members would transfer by spacewalk to a compartment in the stretched Gemini capsule. It would then boost itself on a transearth trajectory. This was rejected in favor of the more flexible Gemini Lunar Surface Rescue Vehicle.|

This version of Gemini was studied as a means of rescuing an Apollo CSM crew stranded in lunar orbit. The Gemini would be launched unmanned on a translunar trajectory by a Saturn V. Following lunar orbit insertion it would automatically rendezvous with the disabled Apollo. The three Apollo crew members would transfer by a spacewalk to the passenger compartment of the stretched Gemini reentry module. It would then boost itself and the rescued crew to a transearth trajectory. This version was rejected in favor of the more flexible Gemini Lunar Surface Rescue Vehicle.
