Abstract
Lunar Laser Ranging (LLR) measures the distance between observatories on Earth and retro-reflectors on the Moon since 1969. In this Letter, we study the possible violation of the equivalence of passive and active gravitational mass (ma/mp), for aluminum (Al) and iron (Fe), using LLR data. Our new limit of 3.9×10-14 is about 100 times better than that of Bartlett and Van Buren [Equivalence of Active and Passive Gravitational Mass Using the Moon, Phys. Rev. Lett. 57, 21 (1986)PRLTAO0031-900710.1103/PhysRevLett.57.21] reflecting the benefit of the many years of LLR data.

N1 - Funding Information: Current LLR data are collected, archived, and distributed under the auspices of the International Laser Ranging Service (ILRS) . We acknowledge with thanks that the processed LLR data, since 1969, has been obtained under the efforts of the personnel at the Observatoire de la Côte d’Azur in France, the LURE Observatory in Maui, Hawaii, the McDonald Observatory in Texas, the Apache Point Observatory in New Mexico, the Matera Laser Ranging observatory in Italy, and the Wettzell Laser Ranging System in Germany. This research was funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) under Germany’s Excellence Strategy EXC 2123 QuantumFrontiers, Project-ID 390837967. We also thank James G. Williams, California Institute of Technology for an extensive discussion on the effect of the degree 2 tides. Without his help, this publication would not have been possible.
