MICROSCOPE

Also known as Micro-Satellite with Compensated Drag for Observing the Principle of Equivalence, Microsatellite with Compensated Drag for Observing the Principle of Equivalence

The '''Micro-Satellite à traînée Compensée pour l'Observation du Principe d'Equivalence (Micro-Satellite with Compensated Drag for Observing the Principle of Equivalence, MICROSCOPE''') is a class minisatellite operated by CNES to test the universality of free fall (the equivalence principle) with a precision to the order of , 100 times more precise than can be achieved on Earth. It was launched on 25 April 2016 alongside Sentinel-1B and other small satellites, and was decommissioned around 18 October 2018 after completion of its science objectives. The final report was published in 2022.
