NASA’s Double Asteroid Redirection Test (DART) mission intentionally impacted the asteroid Dimorphos on September 26, 2022, and this kinetic impact changed Dimorphos’ orbit around its binary companion Didymos. This first planetary defense test explored technological readiness for this method of asteroid deflection.
美国国家航空航天局(NASA)的双小行星重定向测试(DART)任务于 2022 年 9 月 26 日有意撞击了小行星“双形态”(Dimorphos),这次动能撞击改变了“双形态”绕其伴星“双胞胎”(Didymos)的轨道。这项首次行星防御测试探索了这种小行星偏转方法的技术准备情况。
