About

W. M. Folkner is a leading figure in planetary science and precision astrometry, renowned for his work on lunar laser ranging and spacecraft navigation. His research centers on improving measurements of solar system dynamics, with a focus on the Moon's orbit and the relativistic effects governing planetary motion. Folkner's major contributions include the development of advanced retro-reflector arrays for lunar laser ranging, which enable millimeter-level precision in tracking the Moon's distance—critical for testing general relativity and refining lunar interior models. His 2012 paper on the corner-cube retro-reflector instrument, cited 47 times, exemplifies his role in designing hardware that pushes the boundaries of geodetic and astronomical measurement. Beyond this, Folkner has been instrumental in producing high-accuracy ephemerides for NASA missions, such as the Mars Science Laboratory, ensuring precise navigation to distant planets. His work has accumulated thousands of citations, reflecting its foundational impact on planetary geodesy and fundamental physics. Folkner's legacy lies in bridging experimental innovation with theoretical insight, making him a key figure in modern space science.
