Brief Biography

Dr. Bong Wie is the Vance Coffman Endowed Chair Professor of Aerospace Engineering here at Iowa State University, and is the founding director of  the Asteroid Deflection Research Center ( He is the author of AIAA textbook  Space Vehicle Dynamics and Control (2nd edition, 2008). He has published 150 technical papers and  60 peer-reviewed   journal articles,  and  holds three U.S. patents on control-moment-gyro (CMG) steering logic. In 2006, the AIAA  presented Dr. Wie with the Mechanics and Control of Flight Award for his innovative research on advanced control of complex spacecraft such as solar sails, large flexible space structures, and agile imaging satellites equipped with CMGs. His current research effort focuses on developing an innovative, but yet technically and economically feasible, solution to NASA’s near-Earth object (NEO) Impact Threat Mitigation Grand Challenge through a NIAC (NASA Innovative Advanced Concepts) Phase 2 study for the period of 9/15/12 – 9/15/14.
