About

Peter J. Sharer is a leading architect of navigation and communication systems for deep-space exploration, with a career dedicated to enabling humanity’s return to the Moon and eventual missions to Mars. His research focuses on developing scalable, evolvable infrastructure for lunar operations, particularly through weak-signal GPS architectures that can function in the challenging lunar environment. Sharer’s most influential work, “A Weak-signal GPS Architecture for Lunar Navigation and Communication Systems” (2008, 16 citations), provides a foundational framework for integrating robotic and human mission elements under NASA’s Exploration Initiative. His subsequent studies, including “Lunar Navigation and Communication System Implementation Concept” (2007, 6 citations) and “A Scalable Small-Spacecraft Navigation and Communication Infrastructure for Lunar Operations” (2005, 3 citations), advance practical, cost-effective solutions that support a growing lunar presence. Sharer’s contributions are notable for their emphasis on evolvability—designing systems that can adapt as missions progress from initial robotic scouts to sustained human outposts. His work has directly informed NASA’s strategic planning for lunar infrastructure, making him a key figure in the next era of space exploration.
