  1. Blowing things up with sincerity The “Impact Group”: Betty Pierazzo + Natasha Artemieva & Boris Ivanov • Research Interests: • Role of target properties on the impact cratering process • Impact cratering on various planetary surfaces: Mars, Earth, Moon • Effects of impacts on climate and environment Models allow to verify the physics of the process and study conditions beyond the reach of experiments

  2. Elisabetta Pierazzo Research Projects • Validation and benchmarking of impact codes: A broadbased effort of the impact cratering modeling community (Yr 2) NASA-PGG - CoIs: Keith Holsapple, Kevin Housen + 12 collaborators • Effects of lithologies on impact cratering: Numerical modeling of known terrestrial craters (Yr 2) NASA-PGG - CoIs: N.A. Artemieva & B.A. Ivanov (Russian Acad. Sci., Moscow) 3)Impact cratering on Mars: hydrothermal systems, ejecta and ramparts (Yr 2) NASA-MFR - CoIs: N.A. Artemieva & B.A. Ivanov (Russian Acad. Sci.) 4) 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, CoI) NASA-Atmospheres (UofTX Subcontract; David Goldstein PI) 5)Impacts and environmental catastrophes: A study of the effects of impact events on the climate system(just ended) NASA-Exobiology - Collaboration with NCAR

  3. Elisabetta Pierazzo Validation and benchmarking of impact codes: A broadbased effort of the impact cratering modeling community (Yr 2) NASA-PGG - CoIs: Keith Holsapple, Kevin Housen + 12 collaborators  International with involvement of at least 15 scientists  Two abstracts on first benchmark and validation test

  4. Elisabetta Pierazzo Effects of lithologies on impact cratering: Numerical modeling of known terrestrial craters (Yr 2) NASA-PGG - CoIs: N.A. Artemieva & B.A. Ivanov (Russian Acad. Sci., Moscow) Investigate the role of material properties, target complexities and impact conditions on material ejection  Paper on Meteor Crater (submitted) Cloud, D=108m Intact, D=32.4m vimp=16.7 km/s vimp=11.8 km/s

  5. 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

  6. 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/
