Hypervelocity impact is a fundamental process in planet building and modification. The prevalence of heterogeneous materials (different minerals) as impact targets facilitates complicated shock wave – solid phase interactions. This can lead to locally enhanced pressures and temperatures (excursions) due to natural shock amplification mechanisms. Evidence is presented of these effects in lunar, martian and terrestrial materials.
