This electromechanical "clock", made by General Electric, was used in the film return capsules of Corona photoreconnaissance satellites. Corona, a joint U.S. Air Force/Central Intelligence Agency project, successfully launched over 120 satellites from 1960-1972 that provided imagery of the Soviet Union and other nations. The timer controlled the sequence of events - e.g., jettisoning of the thrust cone cover or parachute deployment - during the reentry and recovery of the film return capsule. This timer was flown on two missions and donated by Robert Andrews to NASM in 1998.
