载人探测小行星的目标星选择

Target Selection for Human Exploration of Asteroid

小行星探测具有目标多样化的特点,通过对小行星的相关物理特性进行分析和归类,以及国内外研究情况,从探测任务的安全性、技术可行性和探测价值3个方面,讨论提出了适于我国开展载人探测的选星方法和原则;按照技术可行性由易至难,将候选星分为3类,分别提出了相应的约束条件和优选条件,筛选出候选星;根据部分目标星轨道设计结果,结合未来运载器的发展规划,对这3类小行星的探测任务特点进行了分析,给出了针对性建议,结果可为我国制定载人小行星探测的战略规划提供参考。

The targets of human exploration to asteroid mission are diversified. Based on the anal- ysis of related physical characteristics and classification, as well as the domestic and overseas re- search, the selection method and principles to acquire target asteroids for Chinese crewed explora- tion mission are presented, from the view of safety, technical feasibility, and mission significance. The target asteroids are divided into three categories, according to the technical feasibility from low to high, the restrictions and optimal principles for each category are put forward, then the selection results are gained. Furthermore, according to trajectory design results of several target asteroids, the mission characteristics of human exploration of the three categories of asteroid are analysed, in which the future development of launch vehicles is taken into account. Some sugges- tions are put forward as reference for future strategic programming.
