Major Costantinos Zagaris is an Assistant Professor of Astronautical Engineering at the Air Force Institute of Technology (AFIT). Major Zagaris entered the Air Force in 2007, through the Reserve Officer Training Corps (ROTC) program at Virginia Tech. He began his active duty career at Edwards Air Force Base (AFB), CA where he led weapons integration flight tests for the B-2 bomber. He was then selected to attend graduate school at AFIT, where he graduated as a distinguished graduate with a Master’s in Astronautical Engineering. His follow-on assignment was at the Space and Missiles Systems Center, Space Development and Test Directorate, Kirtland AFB, NM, where he served as the mission manager for the acquisition and launch of ground-based target vehicles for testing of missile defense systems. He then served as the Deputy Program Manager for Guidance, Navigation, and Control, Air Force Research Laboratory, Space Vehicles Directorate, Kirtland AFB, NM, where he directed research in spacecraft autonomy, control, and navigation. Prior to his current assignment, Major Zagaris was at the Naval Postgraduate School, Monterey, CA, where he earned his PhD in Astronautical Engineering. His research interests include autonomous spacecraft guidance, spacecraft relative motion dynamics, optimal control, and reachability.
