摘要
针对载人小行星探测任务目标选取问题,通过对目标星选取影响因素的定量分析,提出了目标星初选方案。首先根据火箭的运载能力提出目标星轨道参数的筛选条件,然后根据地面观测和尺寸约束提出目标星绝对星等的要求,再根据结构的稳定性和温控要求提出目标星自旋周期的范围,最后按照科学价值并综合考虑其他因素建立目标星选取优化模型,得出目标星优选序列。根据提出的目标星初选方案和具体的任务需求进行载人小行星探测目标星选取,得出了目标星优选序列,证明了该方案合理、有效,为载人小行星探测提供一定的技术参考。
A primary target selection method for crewed asteroid exploration was proposed in this paper after quantitative analysis of the influencing factors. Firstly, the orbital filter criteria were proposed according to the carrying capacity of the launch vehicles. Then the requirements for the absolute magnitude of asteroids were put forward by the constraints of ground-based observation and asteroid size. Next, the range of the rotation period was calculated based on the structural stability and thermal control. Finally, the optimization model was established considering the scientific value combined with other factors. The optimal sequence can be obtained using the optimization model. In consideration of specific mission requirements, the proposed method was applied to the selection of targets for crewed exploration. The final optimal sequence showed its scientificity and efficiency. It laid a foundation for crewed asteroid exploration.
