地点:航天学院1号楼3楼会议室

报告题目:《Recent Advances in Space Vehicle Guidance, Control, and Astrodynamics for Asteroid Exploration and Planetary Defense Missions》(行星防御和小天体探测任务中航天器动力学与控制进展)

报告简介:This talk presents an overview of recent advances in space vehicle guidance, control, and astrodynamics in support of asteroid exploration and planetary defense missions design. Despite the lack of a known immediate impact threat from an asteroid or comet, historical scientific evidence suggests that the potential for a major catastrophe created by an asteroid or comet impacting Earth is very real, and humankind must be prepared for it. Due to the recent Chelyabinsk meteor event that occurred in Russia on February 15, 2013 and a close encounter by asteroid 2012 DA14 on the same day, there is now a further growing national and international interest in developing a global plan to protect the Earth from a catastrophic impact by a hazardous asteroid or comet. This talk is focused on advanced GN&C technology and computational astrodynamics, which will play a key role in future space missions for exploring/mining asteroids and also mitigating the impact threat from hazardous asteroids. An innovative yet practical solution to NASA’s near-Earth object (NEO) impact threat mitigation grand challenge and its flight demonstration mission design are also discussed.

报告人简介: Bong Wie is the Vance Coffman Endowed Chair Professor of Aerospace Engineering and Director of the Asteroid Deflection Research Center at Iowa State University, Ames, Iowa. He received his B.S. in aerospace engineering from Seoul National University in 1975, and M.S. and Ph.D. in aeronautics and astronautics from Stanford University in 1978 and 1981, respectively. In 2006, the AIAA (American Institute of Aeronautics and Astronautics) 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 structures, and agile imaging satellites equipped with control moment gyros. Since 2007, Dr. Wie has been establishing a unique research initiative program at Iowa State to develop innovative yet practical space technologies for mitigating the impact threat of hazardous asteroids or comets. In 2011 – 2014, he was the principal investigator of a NASA Innovative Advanced Concepts (NIAC) Phase 1 & 2 Studies entitled “An Innovative Solution to NASA’s NEO Impact Threat Mitigation Grand Challenge and Its Flight Validation Mission Design.” He has published 200 technical papers including 70 peer-reviewed journal articles. He has three patents on singularity-avoidance steering logic of control moment gyros. He is the author of two AIAA textbooks: Space Vehicle Dynamics and Control (1998) and Space Vehicle Guidance, Control, and Astrodynamics (2015).
