caption_attribution_description: English: Apollo 15's Lunar Ranging Retro Reflector (LRRR). Original Caption: 125:33:21 Dave took this cross-Sun from the south of the LRRR, showing the orientation gnomon and bubble level. The LRRR, reflects laser pulses back to the telescopes on Earth used to illuminate it. By measuring the two-way travel time between the telescope and the LRRR, experiments can determine the distance between the two to a few centimeters and address such issues as Einstein's Theory of General Relativity and the existence of a liquid lunar core. As of February 2005, the retroreflectors deployed on Apollos 11, 14, and 15 were still being used in conjunction with a dedicated facility at the MacDondald Observatory in Texas.
