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
Alain Robert, Valerio Cipolla, Pascal Prieur +14
This paper focus on the description of the design and performance of the MICROSCOPE satellite and its Drag-Free and Attitude Control System (DFACS). The satellite is derived from C…
MICROSCOPE mission analysis, requirements and expected performance
Pierre Touboul, Manuel Rodrigues, Gilles Métris +16
The MICROSCOPE mission aimed to test the Weak Equivalence Principle (WEP) to a precision of . The WEP states that two bodies fall at the same rate on a gravitational fiel…
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…
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…
Exploring the Foundations of the Universe with Space Tests of the Equivalence Principle
Baptiste Battelier, Joël Bergé, Andrea Bertoldi +34
We present the scientific motivation for future space tests of the equivalence principle, and in particular the universality of free fall, at the level or better. Two po…
Validation of the in-flight calibration procedures for the MICROSCOPE space mission
Emilie Hardy, Agnès Levy, Manuel Rodrigues +2
The MICROSCOPE space mission aims to test the Equivalence Principle with an accuracy of . The drag-free micro-satellite will orbit around the Earth and embark a different…
Dealing with missing data in the MICROSCOPE space mission: An adaptation of inpainting to handle colored-noise data
Sandrine Pires, Joel Bergé, Quentin Baghi +2
The MICROSCOPE space mission, launched on April 25, 2016, aims to test the weak equivalence principle (WEP) with a 10^-15 precision. To reach this performance requires an accurate…
Gaussian regression and power spectral density estimation with missing data: The MICROSCOPE space mission as a case study
Quentin Baghi, Gilles Métris, Joël Bergé +3
We present a Gaussian regression method for time series with missing data and stationary residuals of unknown power spectral density (PSD). The missing data are efficiently estimat…
Analytical theory for highly elliptical orbits including time-dependent perturbations
Guillaume Lion, Gilles Métris
Traditional analytical theories of celestial mechanics are not well-adapted when dealing with highly elliptical orbits. On the one hand, analytical solutions are quite generally ex…
Towards an analytical theory of the third-body problem for highly elliptical orbits
Guillaume Lion, Gilles Métris, Florent Deleflie
When dealing with satellites orbiting a central body on a highly elliptical orbit, it is necessary to consider the effect of gravitational perturbations due to external bodies. Ind…
Dealing with missing data: An inpainting application to the MICROSCOPE space mission
Joel Bergé, Sandrine Pires, Quentin Baghi +2
Missing data are a common problem in experimental and observational physics. They can be caused by various sources, either an instrument's saturation, or a contamination from an ex…
Odyssey 2 : A mission toward Neptune and Triton to test General Relativity
Benjamin Lenoir, Bruno Christophe, Agnès Lévy +13
Odyssey 2 will be proposed in December 2010 for the next call of M3 missions for Cosmic Vision 2015-2025. This mission, under a Phase 0 study performed by CNES, will aim at Neptune…
