Constraint on intermediate-range gravity from earth-satellite and lunar orbiter measurements, and lunar laser ranging
In the experimental tests of gravity, there have been considerable interests in the possibility of intermediate-range gravity. In this paper, we use the earth-satellite measurement of earth gravity, the lunar orbiter measurement of lunar gravity, and lunar laser ranging measurement to constrain the intermediate-range gravity from λ = 1.2×10m−3.8×10m. The limits for this range are α = 10−5×10, w...
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 کاملSimultaneous laser ranging and communication from an Earth-based satellite laser ranging station to the Lunar Reconnaissance Orbiter in lunar orbit
We report a free space laser communication experiment from the satellite laser ranging (SLR) station at NASA Goddard Space Flight Center (GSFC) to the Lunar Reconnaissance Orbiter (LRO) in lunar orbit through the on board one-way Laser Ranging (LR) receiver. Pseudo random data and sample image files were transmitted to LRO using a 4096-ary pulse position modulation (PPM) signal format. Reed-Sol...
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, ...
