Impact Cratering Calculations

Abstract

Impact cratering, both normal and oblique, on planetary surfaces is discussed and energy partitioning, ejecta distribution, (both with regard to size, velocity, energy content, and size sorting), the condensation physics of impact induced vapor, and the loss of planetary atmospheres during accretion of terrestrial and icy planets are considered. The possible origin of SNC meteorites, impact into porous regolith, equation of state of water and ice, and a possible model for the accretion of the Jovian and Saturnian satellites are examined.
