This artifact is a full-scale mockup of the Gemini spacecraft reentry vehicle, but lacks the white adapter modules of the complete orbital spacecraft. This mockup is a non-functional model recreating the basic appearance of the vehicle and was used for astronaut training. The NASA Marshall Space Flight Center in Huntsville, Alabama, transferred title to the Smithsonian in 1975.
