Lunar Laser Ranging Experiment

Since then, the range from Earth to Moon has been measured at intervals, over a period of more than 30 years. Lunar ranging provides information that is potentially useful for a number of purposes, including providing tests of general relativity.

As of 2002 work is progressing on increasing the accuracy of the Earth-Moon measurements to near millimeter accuracy.
