TL;DR: The MICROSCOPE satellite aims to test its validity at the 10^{-15} precision level, by measuring the force required to maintain two test masses exactly in the same orbit, by characterizing the relative difference in their free-fall accelerations.

TL;DR: The Solar System Odyssey mission as discussed by the authors uses modern-day high-precision experimental techniques to test the laws of fundamental physics which determine dynamics in the solar system, which could lead to major discoveries by using demonstrated technologies and could be flown within the Cosmic Vision time frame.

TL;DR: In this paper, the Weak Equivalence Principle (WEP) was tested to a precision of $10^{-15} by using two masses of different compositions (titanium and platinum alloys) on a quasi-circular trajectory around the Earth.

TL;DR: In this article, the authors developed a method to calculate the force of the Pioneer anomaly with very high precision by means of finite element (FE) modeling and ray tracing algorithms, which can be used for many future fundamental physics (in particular gravitational physics and geodesy missions like LISA, LISA Pathfinder or MICROSCOPE) for which an exact disturbance modelling is crucial.

TL;DR: In this article, a ray tracing algorithm was developed that allows the computation of the resulting surface forces for complex spacecraft geometries, based on the modeling of the spacecraft geometry in finite elements (FEs).
