Lunar Ranging, Gravitomagnetism, and APOLLO
The technique of lunar laser ranging (LLR) has for many decades contributed to cutting-edge tests of the fundamental nature of gravity. These include the best tests to date of the strong equivalence principle, the time-rate-of-change of the gravitational constant, gravitomagnetism, the inverse square law, and preferred frame effects. The phenomenologies of each are briefly discussed, followed b...
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, ...
متن کاملLunar Laser Ranging, Gravitomagnetism and Frame-Dragging
During the past century Einstein’s theory of General Relativity gave rise to an experimental triumph, however, there are still aspects of this theory to be measured or more accurately tested. One of the main challenges in experimental gravitation, together with the direct detection of gravitational waves, is today the accurate measurement of the gravitomagnetic field generated by the angular mo...
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 کاملProspects on measuring intrinsic gravitomagnetism with Lunar Laser Ranging
In this note we explore the possibility of measuring the action of the intrinsic gravitomagnetic field of the rotating Earth on the orbital motion of the Moon with the Lunar Laser Ranging (LLR) technique. Indeed, expected improvements in it should push the precision in measuring the Earth-Moon range to the mm level; the present-day Root-Mean-Square (RMS) accuracy in reconstructing the radial co...
