NEA Sample Return Seminar: Mar 7, 2018

Lecturer: Brent Barbee, Goddard Space Flight Center

Brent W. Barbee is an Aerospace Engineer in the Navigation and Mission Design Branch of NASA’s Goddard Space Flight Center; he is also adjunct graduate faculty in the Department of Aerospace Engineering at The University of Maryland, where he teaches graduate courses. Mr. Barbee supported flight dynamics for launch of the OSIRIS-REx asteroid sample return mission, which launched successfully on September 8th, 2016, is the technical lead for NASA’s Near-Earth Object Human Space Flight Accessible Targets Study (NHATS), is managing work on the Double Asteroid Redirect Test (DART) mission at GSFC, and conducts research on planetary defense against hazardous near-Earth objects (NEOs). Mr. Barbee is a recipient of NASA’s Early Career Achievement Medal and the AIAA National Capital Section 2012-2013 Hal Andrews Young Engineer/Scientist of the Year Award. He received his Bachelor and Master of Science degrees in Aerospace Engineering from the University of Texas at Austin.
