The Laser Ranging Retroeflector (LRRR) is an optical corner reflector used to measure lunar librations (both in latitude and longitude), the recession of the moon from the Earth due to tidal dissipation, and the irregular motion of the Earth, including the Chandler wobble of the poles. This is accomplished by using the technique of short-pulse laser ranging. NASA astronauts placed 3 LRRR's on the lunar surface. The LRRR of Apollo 14 differed in only main design aspects from that on Apollo 11. The LRRR on Apollo 15 was the largest, with 300 separate sub-reflectors - The previous two had only 100. The Apollo 15 array consisted of a hinged, two panel assembly (204 and 94 reflectors) mounted on a leg assembly, which was deployed by the astronaut. The larger array was to allow smaller telescopes on Earth to receive signals from it, but a report on July 31, 1971 showed that the larger array was comparable, but not superior, to the smaller arrays.
