The Laser Ranging Retroreflector (LRRR) is a passive scientific experiment first deployed on the Moon during the Apollo 11 mission in 1969, and subsequently on Apollos 14 and 15.
By firing powerful laser pulses from Earth at these reflectors and precisely measuring the round-trip travel time of the light, scientists calculate the distance to the Moon with millimeter-level precision. #space #nasa
