This is an inertial platform for the Gemini program, which carried ten two-person crews into Earth orbit between March 1965 and November 1966. It consists of a set of gyroscopes and accelerometers, which maintain a fixed position relative to the motions of the spacecraft. The Gemini program pioneered the ability of a crew to change the spacecraft's orbit and to rendezvous with other craft while in orbit -- two critical requirements for the Apollo lunar missions that followed.
The artifact was manufactured by Honeywell, Inc. and donated to the Museum by NASA. It is unflown.
