MICROSCOPE Mission: First Results of a Space Test of the Equivalence Principle. [PDF]

open access: yesPhysical Review Letters, 2017
According to the weak equivalence principle, all bodies should fall at the same rate in a gravitational field. The MICROSCOPE satellite, launched in April 2016, aims to test its validity at the 10^{-15} precision level, by measuring the force required to
