我国小行星探测发展思路及关键技术探讨

介绍了国外小行星探测的发展状况，指出小行星探测正从飞越和伴飞探测向表面软着陆取样返回探测发展，从无人探测向载人探测发展，向多目标探测以及与新技术验证相结合的发展趋势和特点。提出我国小行星探测应分4步走的发展规划和发展思路建议，并论述了小行星探测包括载人小行星探测需要解决的轨道设计、自主采样等关键技术。以上建议和研究可为我国制定小行星深空探测战略规划提供参考。

Study on Development Idea of Chinese Asteroid Exploration and Key Technologies

The development of foreign countries’ asteroid exploration is reviewed.The characteristic and trend of asteroid exploration are those changing from flyby and flying around to soft landing and sampling return exploration,and from unmanned to manned exploration,and that a single mission conducts exploring multiple targets and integrates with new techniques validation.An evolution planning which divides Chinese asteroid exploration into four stages is proposed and discussed.At last,some key technologies which must be solved to develop asteroid exploration are analyzed,such as orbit design and autonomous sampling and so on.The study will supply reference for Chinese asteroid exploration strategy development.
