太阳系边际探测飞行任务规划

针对太阳系边际探测任务,开展了星际多目标飞越的任务规划,采用小推力混合优化设计方法完成了基于借力飞行及电推进技术的行星际转移轨道联合优化设计,对比研究了面向日球层鼻尖和尾部探测的星际多目标探测飞行方案。研究表明,探测器在2024-2025年发射,可飞抵日球层鼻尖区域,在2027-2030年发射可飞抵日球层尾部区域,并可在2049年1月1日前飞离日心100 AU,实现太阳系边际空间的科学探测。其中日球层鼻尖探测任务探测器飞抵100 AU的位置位于鼻尖中心区域,可与旅行者1号、2号探测器形成有效互补。文章所用任务规划方法,可为太阳系边际探测的自主任务规划技术提供基础,相关研究成果能够为未来中国首次太阳系边际探测任务的实施提供有价值的参考。

Flight Mission Planning for Solar System BoundaryExploration

Mission planning of interplanetary multi objectiveflyby is carried out for solar system boundary exploration, and theoptimization of low thrust interplanetary transfer orbit combined with planetgravity assistance is completed. Based on the above research, theinterplanetary flight schemes for the exploration of the tip and tail of theheliosphere are given. The results show that a probe launched during 2024-2025and 2027-2030 can arrive at about 100 AU from the solar center before 2049, andtouch the nasal tip and tail of the heliosphere. Among them, the tip exploreris located in the central region of the nose tip when it flies to the distanceof 100 AU, which can effectively complement the Voyager 1 and Voyager 2. Themission planning method used in this paper can provide the basis for theautonomous mission planning technology of solar system boundary exploration,and the relevant research results can provide valuable reference for theimplementation of the first solar system boundary exploration mission in Chinain the future.
