摘要
小天体上保存着太阳系形成初期的原始成分,同时可能蕴含着地球生命与水起源的重要线索,是研究太阳系起源和演化历史的活化石。近年来,小行星探测已成为主要航天国家深空探索领域的重点发展目标之一。简要总结了国际上小天体探测历程,对小行星探测的研究和发展趋势进行了综述,重点探讨了未来小行星探测任务面临的主要关键技术,并对中国后续开展小行星探测活动提出了相关建议。
The small bodies retain the original elements of early solar system,and may contain important clues to the origin of the earth's life and water.They are living fossils for studying the origin and evolutionary history of the solar system.Asteroid exploration has become research hotspots of international deep space exploration in recent years.The process of small bodies exploration is briefly summarized,and the research and development of asteroid exploration is reviewed,as well the key technologies of asteroid missions.Based on the deep space exploration capability of China,some suggestions are put forward to carry out future asteroid exploration.
