Lunar Laser Ranging Tests of the Equivalence Principle with the Earth and Moon
A primary objective of the Lunar Laser Ranging (LLR) experiment is to provide precise observations of the lunar orbit that contribute to a wide range of science investigations. In particular, time series of the highly accurate measurements of the distance between the Earth and Moon provide unique information used to determine whether, in accordance with the Equivalence Principle (EP), both of t...
متن کاملTests of Gravity Using Lunar Laser Ranging
Lunar laser ranging (LLR) has been a workhorse for testing general relativity over the past four decades. The three retroreflector arrays put on the Moon by the Apollo astronauts and the French built arrays on the Soviet Lunokhod rovers continue to be useful targets, and have provided the most stringent tests of the Strong Equivalence Principle and the time variation of Newton's gravitational c...
متن کاملLunar laser ranging
Lunar laser ranging has provided many of the best tests of gravitation since the first Apollo astronauts landed on the Moon. The march to higher precision continues to this day, now entering the millimeter regime, and promising continued improvement in scientific results. This review introduces key aspects of the technique, details the motivations, observables, and results for a variety of scie...
متن کاملAPOLLO: Multiplexed Lunar Laser Ranging
The Apache Point Observatory Lunar Laser-ranging Operation (APOLLO) is a nextgeneration lunar laser ranging (LLR) campaign aimed at order-of-magnitude improvements in tests of gravitational physics via millimeter range precision. We will employ the 3.5 m telescope at the Apache Point Observatory (APO), located in southern New Mexico at an altitude of 2800 m. As a result of the large aperture si...
متن کاملGravitomagnetism, Frame-dragging and Lunar Laser Ranging
Gravitomagnetism is a phenomenon predicted by Einstein’s theory of General Relativity, it consists in the interaction generated by a mass current in a way formally similar to magnetism generated by an electric current. A number of experiments have been proposed and carried out to accurately measure the gravitomagnetic interaction. The LAGEOS satellites observations [1], using the GRACE models, ...
