About

Suwen Wang is a leading figure in precision space geodesy, best known for his instrumental contributions to lunar laser ranging (LLR) technology. His most-cited work, the 2012 paper "Corner-cube retro-reflector instrument for advanced lunar laser ranging" (47 citations), details the design and development of a next-generation retro-reflector array for the Moon. This innovation dramatically improves the accuracy of measurements of the Earth-Moon distance, enabling tests of general relativity, studies of lunar interior structure, and refinements of celestial mechanics. Wang’s research focuses on the intersection of optical engineering and planetary science, where he has advanced the precision of retro-reflector arrays to sub-millimeter levels. His work has been instrumental in supporting the Apache Point Observatory Lunar Laser-ranging Operation (APOLLO) and other high-precision ranging facilities. By pushing the limits of how we measure the Moon’s orbit and rotation, Wang has helped transform LLR from a geodetic tool into a powerful laboratory for fundamental physics, earning him recognition as a key architect of modern lunar ranging instrumentation.
