High-speed impact is a fundamental process within our Solar System: it is responsible for planet building and planet modification, and has influenced the evolution of life on Earth. The proposed research program will focus on the high strain rate behaviour of planetary materials, with emphasis on describing and understanding friction and shock phenomena. Samples from terrestrial impact structures, as well as lunar, martian and asteroid materials, will be characterized to better comprehend their response to conditions of extreme loading and deformation. This will be achieved by field studies, mission science, and experimental work, while providing world-class training opportunities for students.

高速撞击是我们太阳系内的一个基本过程：它负责行星的建造和行星的修改，并影响了地球上生命的进化。拟议的研究计划将侧重于行星材料的高应变率行为，重点是描述和理解摩擦和冲击现象。将对来自地球撞击结构以及月球、火星和小行星材料的样品进行定性，以更好地了解它们对极端载荷和变形条件的反应。这将通过实地研究，使命科学和实验工作来实现，同时为学生提供世界一流的培训机会。
