About

Glenn Sellar is a planetary scientist whose work centers on lunar geology, volcanism, and the development of in-situ exploration tools. His most significant contribution is the **Moon Diver mission concept**, which proposes sending a rover to rappel into a deep lunar pit in Mare Tranquillitatis. This bold concept aims to directly examine exposed strata in the pit wall, offering an unprecedented window into the Moon’s volcanic history and the formation of secondary crusts. The two foundational papers on Moon Diver have together garnered nearly 50 citations, reflecting strong interest in this innovative approach to planetary exploration. Sellar’s earlier work also advanced the practical side of lunar science, including a multispectral micro-imager designed to give astronauts field-geology capabilities on the Moon, and a reference suite for testing instruments that could help astronauts “high-grade” samples for return to Earth. By bridging the gap between Apollo-era discoveries and future robotic or human missions, Sellar’s research is helping to define how we will explore the Moon’s hidden volcanic layers and prepare for the next generation of lunar fieldwork.
