Successful lunar laser range measurements to the retroreflectors were first reported by the 3.1 m telescope at Lick Observatory, Air Force Cambridge Research Laboratories Lunar Ranging Observatory in Arizona, the Pic du Midi Observatory in France, the Tokyo Astronomical Observatory, and McDonald Observatory in Texas.
The uncrewed Soviet "Lunokhod 1" and "Lunokhod 2" rovers carried smaller arrays. Reflected signals were initially received from "Lunokhod 1", but no return signals were detected after 1971 until a team from University of California rediscovered the array
