Greg Chavers

Acting Deputy Associate Administrator, Systems Engineering and Integration, Human Exploration and Operations Mission Directorate, NASA

Dr. Greg Chavers is the acting deputy associate administrator (DAA) for Systems Engineering and Integration (SE&I) in NASA’s Human Exploration and Operations Mission Directorate (HEO). In this role, Chavers is charged with implementing directorate-level strategies that are responsive to national priorities and NASA’s vision for human spaceflight. He applies more than 30 years of engineering and program management experience to serve SE&I’s objectives to establish human spaceflight requirements across HEO, develop human mission architectures for the Moon and Mars, formulate programs, and integrate science and technology utilization goals into the architectures.

Most recently, Dr. Chavers was deputy manager of NASA’s human landing system (HLS) Program, and prior to HLS program formulation, he was a lead developer of HLS requirements and government reference architecture. As HLS deputy program manager, Dr. Chavers was jointly responsible for leading the development of an integrated human lunar landing system for the Artemis program.

From 2018 until 2020, Chavers was the formulation manager of HEO’s Advanced Cislunar and Surface Capabilities, managing a team of more than 200 civil servants and contractors developing landing system risk reduction technologies and partnerships with U.S. industry. In this role, he developed Lunar CATALYST, NASA’s groundbreaking foray into public-private partnerships to advance lunar landing capabilities, and initiated the work that led to the current HLS Program. Before that, he managed multiple lunar lander projects at NASA’s Marshall Space Flight Center, and was lead systems engineer for Mighty Eagle, a full-scale robotic prototype lander that completed more than 40 terrestrial flights.
Dr. Chavers earned his bachelor’s degree in aerospace engineering from Auburn University, and his master’s and doctoral degrees in physics from the University of Alabama, Huntsville.

Throughout his more than three decades of service to NASA, Chavers has received more than 30 awards for his contributions to spaceflight programs. He also holds two patents in radio frequency technologies.
