具体来说，就是在距地球1000万公里左右的地方，对迎面来的小天体发射动能撞击器，交会后争取能够 产生极大的动能从而改变小天体的轨道。比如，目前计划能够改变3到5厘米的轨道，让小行星至少几十 年到100年之内不能够再撞击地球。 近日召开的第三届深空探测天都国际会议上，中国探月工程总设计师吴伟仁介绍，我国正在规划对一颗 小行星实施动能撞击演示验证任务，验证小行星防御方案可行性。 吴伟仁院士介绍，这项任务拟采用"伴飞+撞击+伴飞"的任务模式，发射观测器和撞击器。观测器先期 抵达对目标小行星进行抵近观测，获取其详细特性参数，然后撞击器对小行星实施高速撞击。撞击全过 程将通过天地联合方式，采用近距离高速成像等技术，开展小行星轨道、形貌和溅射物变化观测，准确 评估撞击效果。 "如果全球共享数据，共同掌握科学成果，最后我们可能得出来更加精确的结论和科学的认知，对我们 整个人类都是有好处的。"吴伟仁说。 （文章来源：人民网） 据介绍，小行星探测、防御和资源开发对于全人类具有深远战略意义，也是国际社会的广泛共识。我国 将向全球伙伴发出合作倡议，在地面联合监测、联合研制与载荷搭载、数据与成果共享等方面开展积极 合作。 ...

Group 1 - The core viewpoint of the article is that China is planning a kinetic impact demonstration mission on an asteroid to validate asteroid defense strategies [2] - The mission will utilize a "flyby + impact + flyby" model, involving the launch of an observer and an impactor [2] - The observer will first reach the target asteroid for close observation to gather detailed characteristic parameters before the impactor executes a high-speed impact [2] Group 2 - The entire impact process will be monitored through a combination of ground and space methods, employing high-speed imaging technology to observe changes in the asteroid's orbit, morphology, and ejecta [2] - The exploration, defense, and resource development of asteroids hold significant strategic importance for humanity and are widely recognized by the international community [2] - China will issue a cooperation initiative to global partners, focusing on joint monitoring, collaborative development and payload integration, as well as data and results sharing [2]

Core Viewpoint - The Tianwen-2 mission represents China's first attempt to conduct asteroid sample return and flyby exploration of a main belt comet, with a planned launch by the end of May 2023 [1][3]. Group 1: Mission Objectives - The Tianwen-2 mission aims to explore asteroid 2016HO3, which is the first known quasi-satellite of Earth, with a diameter of approximately 40-100 meters and a rotation period of about 28 minutes [3][5]. - The mission will also investigate main belt comet 311P, which has an average diameter of about 480 meters and an orbital period of approximately 3.24 years [6][8]. - The mission's scientific goals include determining the physical parameters of both celestial bodies, such as orbital and rotational characteristics, surface composition, and internal structure [10][11]. Group 2: Scientific Significance - Asteroid 2016HO3 is considered a "living fossil" that retains primordial information about the early solar system, making it valuable for studying the composition and evolution of solar system materials [5][10]. - The analysis of samples returned from 2016HO3 will provide insights into the origins and evolution of asteroids, as well as the early solar system's formation processes [11][13]. - The exploration of 311P aims to address scientific questions regarding the nature of main belt comets and their formation, potentially reshaping current understanding of these celestial bodies [11][12]. Group 3: Future Plans - The Tianwen-2 mission is part of a broader Chinese planetary exploration program that includes future missions to Mars and the Jupiter system, with plans for Tianwen-3 and Tianwen-4 to achieve Mars sample return and Jupiter exploration, respectively [12][14]. - The mission is expected to enhance China's position in international space exploration activities, particularly in the field of asteroid defense and resource utilization [13][14].
