Lunar Laser Ranging experiment
Lunar Laser Ranging (LLR) is the practice of measuring the distance between the surfaces of the Earth and the Moon using laser ranging. The distance can be calculated from the round-trip time of laser light pulses travelling at the speed of light, which are reflected back to Earth by the Moon's surface or by one of five retroreflectors installed on the Moon during the Apollo program (11, 14, and 15) and Lunokhod 1 and 2 missions. A review of Lunar Laser Ranging is available. Laser ranging measurements can also be made with retroreflectors installed on Moon-orbiting satellites such as the LRO.
