Extremely rare Gemini spacecraft attitude and translational hand controller in its gray metal housing, measuring an overall 13.5″ x 12″ x 5″, featuring a trainer-type handle grip with non-functional microphone buttons in the style used on Gemini 3 through 7. The part numbers stamped on the housing have been rendered partially indistinct. The three-axis controller design allowed an astronaut to adjust pitch, roll, and yaw of the spacecraft: a back-and-forth motion controlled pitch, a side-to-side motion controlled roll, and a twisting motion controlled yaw. The fly-by-wire Gemini controller represented a significant advancement in technology over the one used during the Mercury Program, which relied largely upon mechanical linkages; proven as reliable during the Gemini spaceflights, the fly-by-wire three-axis controller was subsequently further refined for Project Apollo. In fine condition, with expected signs of use and wear.
