Collection Item Summary:

This Inertial Measurement Unit was carried on the Apollo 7 spacecraft, the first Apollo mission to carry a human crew, in October 1968. It measured accelerations and the position of the spacecraft in the Zero-G environment of Earth orbit. Those data were then used by the crew and the on-board digital computer to maneuver the spacecraft during its mission, and to position it for a safe return to Earth.

NASA transferred this object to the Musuem in 1975.
