近年来,各国针对近地小行星的威胁及相应防御技术的研究越来越多,尤其是美欧合作开展的近地小行星防御任务已进入实质性研制阶段。本文从美欧合作的“小行星撞击和偏转评估”任务的背景入手,概述了近地小行星防御技术的分类,以及任务的基本情况,以期为我国近地小行星防御技术的发展提供参考。
In recent years,there are more and more researches on the threat of near-Earth asteroid defense and the corresponding defense technology.The paper begins with the context of U.S.-European Joint Asteroid Impact & Deflection Assessment(AIDA) Mission,the classification of near-Earth asteroid defense technology and the basic situation of the mission are summarized.It is expected to provide reference for the development of near-Earth asteroid defense technology in China.
