The Laser Ranging Retroreflector is a device that reflects light so that the paths of the reflected rays are parallel to those of the incident rays. Instruments placed on the lunar surface were used in experiments to reflect laser light back to Earth. The reflected light was used to provide precise measurements of the distance between the earth and the moon.

The Bendix Corporation donated this traning unit to the Museum in 1972.
