The MICROSCOPE mission tested the Weak Equivalence Principle by measuring accelerations of free-falling objects in a satellite orbiting Earth. Researchers found that the accelerations of pairs of objects differed by no more than about one part in 10^15, ruling out any violations of the Weak Equivalence Principle or deviations from the current understanding of general relativity at that level. The final results will be published in Physical Review Letters and a special issue of Classical Quantum Gravity on September 14.
