About
Greg Chavers is a leading aerospace engineer whose work is central to NASA’s ambitious lunar exploration strategy. His primary research areas encompass precision landing systems and human-rated spacecraft development for the Moon. Chavers made a major contribution as a key architect of APLNav, a passive optical terrain relative navigation system that enables spacecraft to land safely and accurately on the lunar surface or small planetary bodies. This technology, detailed in his most-cited paper (19 citations), is critical for future missions requiring pinpoint landings. He also played a pivotal role in shaping NASA’s Human Landing System (HLS) strategy, authoring the foundational 2020 paper (15 citations) that outlined the agency’s plan for a sustainable return to the Moon by 2024. Beyond these flagship contributions, Chavers has advanced robotic lunar lander projects through risk reduction studies at NASA Marshall Space Flight Center and the Johns Hopkins Applied Physics Laboratory. His work directly supports the Artemis program, bridging the gap between cutting-edge navigation technology and the operational systems needed to establish a permanent human presence on the Moon.
