S66-28075 (May 1966) --- Insignia of the Gemini IX spaceflight. Roman numeral indicates ninth flight in the Gemini series. Two spacecraft symbolize rendezvous and docking of Gemini with an Agena. Astronaut and umbilical (tether) line denote planned extravehicular activity (EVA). Astronauts Thomas P. Stafford, command pilot, and Eugene A. Cernan, pilot, are members of the Gemini IX prime crew.
The NASA insignia design for Gemini flights is reserved for use by the astronauts and for other official use as the NASA Administrator may authorize. Public availability has been approved only in the form of illustrations by the various news media. When and if there is any change in this policy, which we do not anticipate, it will be publicly announced. Photo credit: NASA
