NASA space-flown Gemini medallions were mission-specific commemorative medallions which were approved by NASA and carried aboard the mission spacecraft into orbit. Gemini 4 was the second crewed mission in the Gemini program. In June 1965, astronauts James McDivitt and Ed White flew sixty-six Earth orbits in their spacecraft. The highlight of the mission was the first space walk by an American, during which White floated free outside the spacecraft, tethered to it, for approximately twenty minutes.
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 one bore the word "Fliteline".Photograph credit: Heritage Auctions; commissioned by the NASA astronaut office
