Abstract
LLR measures the distance between observatories on Earth and retro-reflectors on Moon since 1969. In this paper, we study the possible violation of the equality of passive and active gravitational mass (), for Aluminium (Al) and Iron (Fe), using LLR data. Our new limit of is about 100 times better than that of Bartlett and Van Buren [1986] reflecting the benefit of the many years of LLR data.
