Michiharu Wada,Peter Schury,Yuichi Ichikawad as a candidate for ESA’s M2 mission as a joint mission with NASA, and has since been studied as an M3 candidate, and under NASA as QuickSTEP and MiniSTEP. Studies especially during the last two years have resolved some long standing issues such as control of helium tide, improved the mission defin

This produces several key tests of that tensor theory of gravity and strongly constrains presence of any supplementary interactions. Earth and Moon fall toward the Sun at rates equal to a couple parts in 1013, confirming both the universal coupling of gravity to matter

Navneet Gupta,Adam Makosiej,Costin Angheln of the Equivalence Principle through the observation of a variation of the fine structure constant, α. A spatio-temporal variation of α is expected in some string theories aimed at unifying gravity with other forces in nature. SpaceTime uses a special tri- clock instrument on a spacecraft which ap

An Overview of Solar System Gravitational Physics: The Theory—Experiment Interface then General Relativity’s Equivalence Principle foundations are violated, or its post-Newtonian (1/..order) structure is altered, or both. Space experiments test for and measure such possibilities; presently universality of free fall is confirmed to about a part in 10., and no deviations of post-Ne

Determination of the Gravitational Constante in a rather sad shape. Recently, the CODATA Task Group on Fundamental Constants recommended a preliminary value of . with a relative uncertainty of 0.15 %. This is more than ten times larger as the previous recommendation!.In the first part of this lecture, a brief summary is given of recent exper
