NASA space-flown Gemini medallions were mission-specific commemorative medallions which were approved by NASA and carried aboard the mission spacecraft into orbit. Gemini 6A was a mission in the Gemini program. On December 15, 1965, astronauts Wally Schirra and Thomas P. Stafford were launched into space where they made the first crewed rendezvous with another spacecraft, Gemini 7; the two craft came within a foot (30 cm) of each other, and could have docked had they been equipped to do so.
Fliteline medallions were made for each of the crewed Gemini flights, being prepared for the astronauts at their request. It is unclear who prepared these early medallions, only that each individual box containing a medallion bore the word "Fliteline".Photograph credit: Heritage Auctions; commissioned by the NASA astronaut office
