摘要
《2021中国的航天》白皮书表示中国行星探测工程将实施小行星探测、火星采样返回、木星系探测等任务,对于更为远期的行星探测任务尚未有明确规划。土星是太阳系第二大行星,拥有美丽的星环和众多天然卫星,其中土卫二可能存在冰下海洋、土卫六是太阳系第二大天然卫星且是唯一一个拥有浓密大气的卫星,均具有极大的科学研究价值。本文对国外土星探测任务的发展状况进行了调研分析,包括已实施的先驱者11号、旅行者1号、旅行者2号、卡西尼-惠更斯号,以及后续的土卫二轨道-着陆器、土卫二多次飞越探测等。对这些任务的特点及实施土星系探测面临的关键难点进行了归纳总结。最后,提出了土星系探测的总体任务设想,进行了任务分析与初步设计,可作为中国后续行星探测任务规划的参考。
According to the white paper“China′s Aerospace 2021”,China′s planetary exploration project will carry out asteroid exploration,Mars sampling return,and Jovian system exploration,but there is no clear plan for more longterm planetary exploration missions.The Saturn is the second largest planet in the solar system,with beautiful rings and many natural satellites,among which the Enceladus may have a subglacial ocean,and the Titan is the second largest natural satellite in the solar system and the only satellite with a dense atmosphere,all of which are of great scientific research value.In this paper,foreign Saturn exploration missions are investigated and analyzed,including Pioneer 11,Voyager 1,Voyager 2,and Cassini-Huygens,as well as the future missions,including Enceladus Orbilander and Enceladus Multiple Flybys.The characteristics of these missions and the key difficulties in the implementation of Saturnian system exploration are summarized.Finally,an overall mission assumption of Saturn system exploration is proposed,and the mission analysis and preliminary design are carried out,which can be used as a reference for China′s follow-up planetary exploration mission planning.
