Result of the MICROSCOPE Weak Equivalence Principle test
Pierre Touboul, Gilles Métris, Manuel Rodrigues +44
The space mission MICROSCOPE dedicated to the test of the Equivalence Principle (EP) operated from April 25, 2016 until the deactivation of the satellite on October 16, 2018. In th…
MICROSCOPE Mission scenario, ground segment and data processing
Manuel Rodrigues, Pierre Touboul, Gilles Métris +9
Testing the Weak Equivalence Principle (WEP) to a precision of requires a quantity of data that give enough confidence on the final result: ideally, the longer the measu…
MICROSCOPE: systematic errors
Manuel Rodrigues, Pierre Touboul1, Gilles Metris +19
The MICROSCOPE mission aims to test the Weak Equivalence Principle (WEP) in orbit with an unprecedented precision of 10 on the Eötvös parameter thanks to electrostatic acce…
MICROSCOPE instrument in-flight characterization
Ratana Chhun, Emilie Hardy, Manuel Rodrigues +11
Since the MICROSCOPE instrument aims to measure accelerations as low as a few 10\,m\,s and cannot operate on ground, it was obvious to have a large time dedicated to…
Constraints on chameleon gravity from the measurement of the electrostatic stiffness of the MICROSCOPE mission accelerometers
Martin Pernot-Borràs, Joël Bergé, Philippe Brax +4
This article is dedicated to the use the MICROSCOPE mission's data to test chameleon theory of gravity. We take advantage of the technical sessions aimed to characterize the electr…
MICROSCOPE's constraint on a short-range fifth force
Joel Bergé, Martin Pernot-Borràs, Jean-Philippe Uzan +5
The MICROSCOPE experiment was designed to test the weak equivalence principle in space, by comparing the low-frequency dynamics of cylindrical "free-falling" test masses controlled…
MICROSCOPE mission: Statistics and impact of glitches on the test of the weak equivalence principle
Joel Bergé, Quentin Baghi, Alain Robert +6
MICROSCOPE's space test of the weak equivalence principle (WEP) is based on the minute measurement of the difference of accelerations experienced by two test masses as they orbit t…
MICROSCOPE mission: Data analysis principle
Joel Bergé, Quentin Baghi, Emilie Hardy +10
After performing highly sensitive acceleration measurements during two years of drag-free flight around the Earth, MICROSCOPE provided the best constraint on the Weak Equivalence P…
MICROSCOPE Satellite and its Drag-Free and Attitude Control System

MICROSCOPE instrument description and validation
Françoise Liorzou, Pierre Touboul, Manuel Rodrigues +19
Dedicated accelerometers have been developed for the MICROSCOPE mission taking into account the specific range of acceleration to be measured on board the satellite. Considering on…
New test of Lorentz invariance using the MICROSCOPE space mission
Hélène Pihan-le Bars, Christine Guerlin, Aurélien Hees +11
We use data from the T-SAGE instrument on board the MICROSCOPE space mission to search for Lorentz violation in matter-gravity couplings as described by the Lorentz violating Stand…
Space test of the Equivalence Principle: first results of the MICROSCOPE mission
Pierre Touboul, Gilles Métris, Manuel Rodrigues +31
The Weak Equivalence Principle (WEP), stating that two bodies of different compositions and/or mass fall at the same rate in a gravitational field (universality of free fall), is a…
The local dark sector. Probing gravitation's low-acceleration frontier and dark matter in the Solar System neighborhood
Joel Bergé, Laura Baudis, Philippe Brax +18
We speculate on the development and availability of new innovative propulsion techniques in the 2040s, that will allow us to fly a spacecraft outside the Solar System (at 150 AU an…
