中国正计划其自身的行星防御任务，旨在直接改变小行星的轨道，甚至将其击碎。这项任务在一篇新论文中有所详述，比NASA的双小行星重定向测试（Dart）更具雄心。中国航天器预计将以超过9公里/秒的速度撞击小行星，远高于Dart的撞击速度，测试预计将于2029年或2030年进行。 AI

中国计划在行星防御测试中用26马赫弹丸撞击小行星

China’s first planetary defence mission appears to be far more ambitious than Nasa’s Double Asteroid Redirection Test (Dart), according to a new paper outlining its plan to slam a spacecraft into an asteroid before 2030. Unlike Dart, a proof-of-concept that nudged one asteroid’s …
