Instructors

Bong Wie is Professor of Aerospace Engineering at Iowa State University. He holds a B.S. in aerospace engineering from Seoul National University and a M.S. and Ph.D. in aeronautics and astronautics from Stanford University. In 2006 he received AIAA’s Mechanics and Control of Flight Award for his innovative research on advanced control of complex spacecraft such as solar sails, large flexible structures, and agile imaging satellites equipped with control moment gyros. He is the author of two AIAA textbooks: “Space Vehicle Dynamics and Control (2nd edition, 2008)” and “Space Vehicle Guidance, Control, and Astrodynamics (2015).” He has published 210 technical papers including 80 journal articles.  He has three US patents on singularity-avoidance steering logic of control moment gyros. In early 2010s, he was actively involved in guidance, control, and astrodynamics research for deflecting or disrupting hazardous near-Earth objects (NEO).     From 2011-2014, he was a NIAC (NASA Advanced Innovative Concepts) Fellow for developing an innovative solution to NASA’s NEO impact threat mitigation grand challenge and its flight validation mission design.  His NIAC study effort has resulted in two distinct concepts for effectively disrupting   hazardous asteroids with short warning time, called a hypervelocity asteroid intercept vehicle (HAIV) and a multiple kinetic-energy impactor vehicle (MKIV). During late 2010s, his research focused on further developing the ZEM/ZEV feedback guidance strategies for robotic/human Mars precision powered descent & landing with hazard avoidance and retargeting.  He is currently exploring a technically challenging, guidance problem of hypersonic missiles/vehicles and an advanced guidance problem of missiles with precision impact time and angle control (ITAC) requirements. He is co-Editor of Astrodynamics, an international journal established in 2018. The following on-demand short courses of Dr. Wie are available from AIAA:
