The MICROSCOPE satellite ended its mission in October 2018. Aiming at testing the Equivalence Principle (EP), the funding hypothesis of the General Relativity with unprecedented precision, a first publication in 2017 showed no evidence of a violation at 10−14 level. Since then; 3 years of analysis made it possible to improve the accuracy by one...

The MICROSCOPE mission tested the Weak Equivalence Principle (WEP) with an unprecedented precision of order 10−15, two orders of magnitude better than the previous best lab experiments. While the WEP, the cornerstone of General Relativity (GR), does not sway, the decade-long problems faced by fundamental physics stay still: how can we unify GR...

MICROSCOPE is a space mission launched in 2016 that aims to test the validity of the Equivalence Principle (EP), the main postulate of General Relativity (GR), with a precision never reached before (Touboul et al. (2001)). EP states that two bodies of different compositions and masses fall with the same acceleration in the same gravitational...

The MICROSCOPE space experiment aimed to test the Equivalence Principle with a much better accuracy than ever before. Its principle is to compare the free fall of concentric test masses embedded in a space accelerometer onboard a satellite orbiting the Earth. The effect of non-gravitational forces on the motion of the satellite is strongly...

The MICROSCOPE space mission aims at testing the Equivalence Principle with an accuracy of 10e-15. To be launched on April 2016, the CNES microsatellite embarks the instrument that should test for the first time in space the foundation of General Relativity. The expected results whether they confirm or not the Equivalence Principle will bring a...

Launched in April 2016, the MICROSCOPE satellite ended its operations in October 2018 with the deployment of its deorbitation wings. MICROSCOPE aims at testing the equivalence principle (EP), the funding hypothesis of general relativity established by Einstein in 1915. In December 2017, first results based on only 7% of the total data improved...

The MICROSCOPE space mission aims at testing the Equivalence Principle (EP) with an accuracy of 10-15. The instrument will be embarked on board a drag-free microsatellite orbiting the Earth, and consists in a differential electrostatic accelerometer composed of two cylindrical test masses submitted to the same gravitational field but made of...

Several space tests of gravity laws have already been performed but the MICROSCOPE mission is the first one to be fully dedicated to the test of the Equivalence Principle. The dedicated payload is now under qualification and the rather large micro satellite will be produced by Cnes for a launch at beginning of 2015. Each of the two differential...

MICROSCOPE is a fundamental physics space mission which aims at testing the Equivalence Principle (EP) with an accuracy of 10-15. The gravitational signal is measured precisely by a differential electrostatic accelerometer which includes two cylindrical test masses made of different materials. The accelerometer is on-board a drag-free...
