  1. Innovative end for Microscope

    Date de publication:

    15 Octobre 2018

    Having reached the end of its mission, the French Microscope satellite is set to perform one last manoeuvre with a new de-orbiting system designed to avert space debris. Isabelle Petitbon, who heads CNES’s fundamental physics programme, and Pierre-Yves Guidotti, Microscope Operations Project Leader, explain.

  3. First gravitational results from Microscope

    Date de publication:

    4 Décembre 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.

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

    Date de publication:

    4 Décembre 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.
