The invention belongs to the field of star mineral composition detection, and particularly relates to a method for detecting star surface composition through ultra-high-speed impact, which specifically comprises the following steps of: throwing a projectile to the surface of a star outside dozens of kilometers on an aircraft in a catapulting manner, and detecting the surface composition of the star by utilizing a high relative speed between the aircraft and the star; and the projectile impacts the surface of the star at an ultra-high speed of kilometer/second and induces high-temperature and high-pressure plasma. The plasma emits strong light and emits discrete atomic spectral lines in the expansion cooling process. A telescope and a high-sensitivity grating spectrometer are arranged on the aircraft, plasma atomic spectral lines are collected and analyzed, and remote star surface component detection is achieved.

    本发明属于星体矿物成分探测领域,具体涉及一种超高速撞击来探测星体表面成分的方法,具体指:在飞行器上以弹射方式向几十公里外的星体表面投掷一弹丸,利用飞行器和星体间的大相对速度,使弹丸以公里/秒的超高速撞击星体表面并诱发高温高压等离子体。等离子体发出强光,并在膨胀冷却过程中发出离散的原子谱线。在飞行器上设置望远镜和高灵敏度光栅光谱仪,对等离子体原子谱线收集分析,实现远距离的星体表面成分探测。
