As one of the potential candidates of the Asteroid Exploration Mission to be launched around 2010, we investigated the feasible mission scenarios. Firstly, according to goal and constraints of the mission, the opportunity for asteroid exploration mission is analyzed. The 4660 Nereus is selected as the candidate. We searched and presented the optimal rendezvous opportunity for 4660 Nereus from 2009 to 2010. Through analyzing the direct transfer trajectory, unexpected result that the trajectory would pass the 12866 asteroid and 7080 asteroid is found. Then, we calculated and optimized the new profile with multiple flybys by using the hybrid search algorithm combining the genetic algorithm with sequential quadratic programming method. Finally, we analyzed the trajectory characteristics and gave some key parameters, which would have a direct impact on communication system, power system, thermal control system of spacecraft, and so on.
