我国规划撞击一颗小行星

Core Viewpoint - The article discusses China's plans for a kinetic impact demonstration mission on an asteroid to validate asteroid defense strategies, emphasizing the importance of international collaboration in asteroid detection, defense, and resource development [1][3]. Group 1: Mission Overview - The mission will utilize a "flyby + impact + flyby" approach, involving the launch of an observer and an impactor to study the asteroid's characteristics before executing a high-speed impact [1]. - The objective is to change the asteroid's trajectory by 3 to 5 centimeters, preventing potential collisions with Earth for several decades to a century [1]. Group 2: International Collaboration - The initiative highlights the strategic significance of asteroid exploration and defense for humanity, with a call for global partnerships in monitoring, joint development, and data sharing [3]. - Sharing data and scientific results globally is expected to lead to more accurate conclusions and a better understanding of asteroid threats, benefiting all of humanity [3].
