Spacecraft reflectors

WebRetroreflectors are devices which reflect light back to its source. Five were left at five sites on the Moon by three crews of the Apollo program and two remote landers of the Lunokhod program. Lunar reflectors have enabled precise measurement of the Earth–Moon distance since 1969 using lunar laser ranging.
