Are There Any Retroreflectors on the Moon? Part 1. | V. Nasennik
This episode is dedicated to the history of Lunar Laser Ranging and the Soviet–French laser ranging experiment. It presents real data on the reflectors located on the surface of the Moon. The discussion covers the experiments with Lunokhod 1 and Lunokhod 2, measurement accuracy, differences between French and American retroreflectors, results obtained in the United States, France, and China, and the reasons for the “weak” returned signals. Separate sections describe the search for Lunokhod 1, the fate of Lunokhod 2, the effects of the atmosphere and optical degradation, and what the obtained figures do and do not confirm.
