Collection Item Summary:
This Inertial Measurement Unit was carried on the Apollo 14 Command Module, crewed by Alan Shepard, Stuart Roosa, and Edgar Mitchell, in January 1971. The device consisted of gyroscopes and accelerometers, which measured accelerations and the position of the spacecraft in the Zero-G environment of space. Data from this unit was used by the crew and by the on-board digital computer to control the spacecraft, and to position it correctly for critical maneuvers as it traveled to and from Lunar orbit.
NASA transferred the object to the Museum in 1975.
