Retroreflectors were placed on the moon by the Apollo 11, 14, and 15 missions, and also by two Russian lander rovers (Lunokhod 1 & 2). Scientists bounce lasers off these reflectors even up to today to determine the small changes in the distance between the moon and the Earth. There are more than 40 years of documented measurements. One of the interesting things this has determined is that the understood tidal dissipation in the Earth/Moon system does not correlate to the predicated age of the Moon's orbit.
