行星探测器的硬着陆撞击

探测太阳系的行星及其卫星是空间科学和航天技术的重要领域之一。近半个世纪以来，人们一直在筹划使用侵彻器在这些星体着陆，为了解决结构动强度，穿星器弹道稳定性和器件耐撞性等难点，人们需要进行弹道试验和理论分析。中国为实现科技现代化作了许多努力，相信中国今后也将会十分重视行星探讨测器的硬着陆研究。

Hard Landing Impact of Planet Probe

The exploration of the planets and their satellites within the solar system is one of the important fields in space science and aerospace technology.Since the late half of this century, penetrators have been considered as landers on these bodies.In order to solve those problems such as dynamic strength of structures,ballistic stability of penetrators and impact resistance of elements, the ballistic tests and theoretical analyses are needed . China has made great efforts for the modernization of science and technolgy.It is believed that more attention to hard landing on planets will be paid by our country.
