Rescue Gemini - A version of Gemini was proposed for rescue of crews stranded in Earth orbit. This version, launched by a Titan 3C, used a transtage for maneuvering. The basic Gemini reentry module was extended to 120 inches (3.05 m) diameter to provide a passenger compartment for the rescued crew. The same concept would eventually be used for Big Gemini.

A version of Gemini was proposed for rescue of crews stranded in Earth orbit. This version, launched by a Titan 3C, used a transtage for maneuvering. The basic Gemini reentry module was extended to 120 inches (3.05 m) diameter to provide a passenger compartment for up to three rescued crew. The same concept would eventually be used for Big Gemini.
