我国规划撞击一颗小行星

Core Viewpoint - China is planning a kinetic impact demonstration mission on an asteroid to validate asteroid defense strategies, as presented by Wu Weiren, the chief designer of the lunar exploration project at the recent Tian Du International Conference on Deep Space Exploration [1]. Group 1: Mission Overview - The mission will utilize a "flyby + impact + flyby" approach, involving the launch of an observer and an impactor [1]. - The observer will first reach the target asteroid for close observation to gather detailed characteristic parameters before the impactor executes a high-speed collision [1]. - The entire impact process will be monitored using a combination of ground and space technologies, including high-speed imaging, to observe changes in the asteroid's orbit, morphology, and ejecta [1]. Group 2: Impact Goals - The mission aims to launch a kinetic impactor at a small celestial body approximately 10 million kilometers from Earth, with the goal of altering the asteroid's trajectory by 3 to 5 centimeters [1]. - This alteration is intended to prevent the asteroid from colliding with Earth for at least several decades to up to 100 years [1]. Group 3: Strategic Significance and Collaboration - Asteroid detection, defense, and resource development hold profound strategic significance for humanity and are widely recognized by the international community [1]. - China plans to issue a cooperation initiative to global partners, focusing on joint monitoring, collaborative development and payload integration, as well as data and results sharing [1]. - Wu Weiren emphasized that global data sharing and collective scientific understanding would lead to more accurate conclusions and benefits for all humanity [1].
