About

D. G. Currie is a pioneering physicist whose career has been defined by a sustained commitment to lunar laser ranging (LLR) and its applications in fundamental physics. Working at the intersection of precision measurement, gravitational theory, and space instrumentation, Currie has played a central role in advancing retroreflector technology for deployment on the Moon. His most celebrated contribution is the MoonLIGHT project — a next-generation lunar laser ranging retroreflector array developed through USA–Italy collaboration — designed to dramatically improve upon the Apollo-era arrays that have served science since 1969. By pushing measurement precision toward the sub-millimeter regime, Currie's work enables rigorous tests of General Relativity, constraints on new physics, and refinements in our understanding of the Moon's internal structure and orbital dynamics. His research has extended to the MAGIA lunar orbiter concept, exploring absolute positioning metrology from orbit. Now, more than five decades after the original Apollo retroreflectors were placed on the lunar surface, Currie remains active, with his MoonLIGHT and MPAc instruments selected for NASA's CLPS missions. His body of work, though specialized, represents an extraordinary continuity of scientific vision spanning generations of lunar exploration.
