Elisabetta Pierazzo Direct Numerical Simulation of Comet Impacts and Low-Density Atmospheric Flow on the Moon and the Effects on Ice Deposition in Cold Traps (Yr 3) NASA-Atmospheres (UofTX Subcontract; David Goldstein PI) Combine 3D hydrocode modeling of impacts with molecular flow of a gas cloud, including chemistry and condensation/sublimation
Elisabetta Pierazzo NASA-E/PO grant: The Explorer's Guide to Impact Craters or “Motivating learning about STEM careers, research, and content through the study of impact craters” Introduce the study of impact craters through 1) virtual tours of impact craters, 2) computer simulations of the impact process, and 3) examination of impact rock samples http://www.psi.edu/explorecraters/
