Graphic of the MICROSCOPE Mission. (IMAGE) American Physical Society Caption Published in Physical Review Letters and a special issue of Classical Quantum Gravity on September 14, the final results from the MICROSCOPE mission measured accelerations of free-falling objects in a satellite orbiting Earth. The team 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.
