  6. Microscope A new CNES satellite to test Albert Einstein’s theory of general relativity

    Publishing date:

    April 15, 2016

    CNES’s Microscope satellite (MICROSatellite à trainée Compensée pour l’Observation du Principe d’Équivalence) was presented to the press today at the agency’s Head Office in Paris. The satellite is set to be orbited Friday 22 April by Soyuz from the Guiana Space Centre. Microscope will test the universality of free fall for the first time in the vacuum of space using an experiment 100 times more precise than anything on Earth.

  7. First results from Microscope satellite confirm Albert Einstein’s theory of relativity with unprecedented precision

    Publishing date:

    December 4, 2017

    Measurements of the equivalence principle had not been improved upon for 10 years, but now the first results from CNES’s Microscope satellite, equipped with accelerometers supplied by the French aerospace research agency ONERA, are 10 times better. They show, with an unprecedented precision of 2.10-14, that bodies in a vacuum fall with the same acceleration. The equivalence principle has so far proved unshakeable and this result simply reconfirms the theory of general relativity postulated by Albert Einstein over a century ago.

  17. First gravitational results from Microscope

    Publishing date:

    December 4, 2017

    Albert Einstein’s theory of general relativity continues to stand the test of time and scientists’ ever deeper probing. The first results from the Microscope satellite have confirmed the equivalence of gravitation and acceleration with unprecedented precision, pushing the limits of Einstein’s theory further than ever before. We talk about these latest findings with Isabelle Petitbon, who heads CNES’s fundamental physics programme, and Pierre-Yves Guidotti, Microscope exploitation project leader.
