编者按:随着人类太空探索的不断深入,国际上针对小行星的研究逐渐增多,小行星探测活动日益成为热点,美国和日本先后开展了多次针对小行星的探测任务,探测形式也由飞越探测发展为就位探测、采样返回等多种形式。其中,美国开展了数量最多、形式多样的小行星探测任务;日本成功实施了小行星采样返回任务,取得了小行星探测的领先地位;中国的嫦娥-2于2014年首次完成了近距离飞越近地小行星图塔蒂斯的任务。目前,加快小行星探测已经成为国内学者和专家的共识,深空探测被列入了“十三五”国家科技重大专 Editor’s Note: With the continuous exploration of human space, the research on asteroids in the world is gradually increasing. Asteroid exploration activities are increasingly becoming hot spots. The United States and Japan have conducted many exploration missions targeting asteroids. Detection of the development of the spot exploration, sampling and other forms of return. Among them, the United States carried out the largest number of asteroid missions in various forms; Japan successfully implemented the asteroid sampling and return mission and achieved the leading position in asteroid exploration; and China’s Chang-E-2 completed its first near-miss overflight in 2014 Near-Earth asteroid Turtas task. At present, accelerating the asteroid exploration has become the consensus of domestic scholars and experts, deep space exploration was included in the “Thirteen Five” national science and technology major
