This  competition was based on the background of multi-tasking and  multi-target exploration of the small bodies in solar system. By  designing optimal control strategy and the flight path, the final result  will realize the exploration of Near-Earth asteroid, main belt  asteroids, and comets with limited thrust or pulse thrust. The  exploration terms include fly-by, impact, rendezvous and sample-return,  which involve low-thrust trajectory optimization, gravity-assist  technology, and global optimization strategies. All of these put forward  higher requirements to the the orbit design level of the contestants.  The competition notice issued in May 2012, and announced the contest  topic on June 10. In total there are 26 teams take part the competition  and the 14 teams submitted the results.

In this  seminar, Many orbit design experts from the domestic aerospace sectors  and teams representatives carried out depth academic exchanges and  discussions on space orbit design issues, and achieved fruitful results.

The seminar is  co-sponsored by the Chinese Society of Theoretical and Applied  Mechanics, Chinese Academy of Space Applications Engineering and  Technology Center, Space Flight Dynamics Technology Laboratory of  National Defense Science and Technology University.
