This rate gyro, designed by Honeywell Inc., was flown on the Gemini 8 mission, on March 16, 1966, piloted by Neil Armstrong and Dave Scott.
Rate gyros were part of the Attitude Control and Maneuver Electronics System for the Gemini spacecraft. Information from this gyro was used in conjunction with inputs from the hand controllers, the inertial platform, computer, and horizon sensor to maintain the spacecraft's attitude throughout all phases of the mission.
Donated to the Museum by Honeywell Inc. in 1970.
This object is on display in Human Spaceflight at the Steven F. Udvar-Hazy Center in Chantilly, VA.
