| 摘 要： | 从数以万计的近地小行星(NEAs)中选择探测目标,是一项非常重要的工作.选择小行星时需要考虑的主要问题是:NEAs的轨道参数、自旋周期、大小、科学价值、表面特征以及到达NEAs的时间.本文采用排除法从众多近地小行星中确定候选者,并根据科学目标的要求确定最终探测目标.

| Abstract: | Selecting a suitable target for a space mission from huge number of discovered near-Earth asteroids (NEAs) has become a matter of immediate concern. The most important factors to consider in targets selection are:the global minimum total velocity increments (Delta-v); travel time to and from the target; NEA orbital parameters, spin cycle, size, expected mineralogical composition; surface morphologies.Based on these factors and the scientific purpose, we identified about hundreds potential targets for the space mission through the exclusive method. The results provide a basic reference for the choice of next-generation mission targets. |
