Space-based Tests of Gravity with Laser Ranging
Existing capabilities in laser ranging, optical interferometry and metrology, in combination with precision frequency standards, atom-based quantum sensors, and drag-free technologies, are critical for the space-based tests of fundamental physics; as a result, of the recent progress in these disciplines, the entire area is poised for major advances. Thus, accurate ranging to the Moon and Mars w...
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 کاملThe impact of the static part of the Earth’s gravity field on some tests of General Relativity with laser–ranging
In this paper we calculate explicitly the secular classical precessions of the node Ω and the perigee ω of an Earth artificial satellite induced by the static, even zonal harmonics of the geopotential up to degree l = 20. Subsequently, their systematic errors induced by the mismodelling in the even zonal geopotential coefficients Jl are compared to the general relativistic secular gravitomagnet...
متن کاملLaser Ranging Delay in the Bi-Metric Theory of Gravity
We introduce a linearized bi-metric theory of gravity with two metrics. The metric gαβ describes null hypersurfaces of the gravitational field while light moves on null hypersurfaces of the optical metric ḡαβ. Bi-metrism naturally arises in vector-tensor theories with matter being non-minimally coupled to gravity via long-range vector field. We derive explicit Lorentz-invariant solution for a l...
متن کاملLunar Laser Ranging - A Comprehensive Probe of Post-Newtonian Gravity
Using more than 30 years of lunar laser ranging (LLR) data, the lunar orbit has been modeled and fit with several millimeters precision. This fit provides comprehensive confirmation of the general relativistic equations of motion for solar system dynamics, achieving several key tests of Einstein’s tensor theory of gravity, and strongly constraining presence of any additional long range interact...
