Gemini 6A (GT-6A), a revised mission of Gemini 6, was launched on December 15, 1965, with pilots Walter M. Schirra and Thomas P. Stafford at the controls. The original plan for Gemini 6 involved rendezvousing with an unmanned Agena target rocket, which was intended solely as a "target" for the manned mission to dock with in Earth orbit. However, the mission was canceled due to a technical failure during the launch of the Agena rocket.

The plan was modified to expedite the launch of Gemini 7, allowing Gemini 6A to rendezvous with it in Earth orbit. Schirra successfully executed the space rendezvous with the Gemini 7 spacecraft. Once in formation, the two capsules flew around each other, coming within a foot (0.3 meters) of one another without making contact. They maintained close proximity for five hours.
