In Room 424 + Webex 11:00 am Jun Du Purdue University How to Model Realistic Lunar Craters?

Abstract: The morphology of fresh lunar craters contains information about the physical properties of the meteorite and the lunar surface and is therefore crucial to our understanding of the impact cratering process. Previous shape models of fresh lunar craters were always developed in an axisymmetric geometry and therefore failed to reproduce the detailed textures of the crater. As a comparison, spectral analysis is a more powerful tool to study crater morphology, as it can reveal the topographic variation of the crater at different scales. In this talk, I will present how to calculate the power spectral densities of the one-dimensional rim crest, floor, and ejecta outlines and the two-dimensional ejecta, wall, and floor elevations of fresh lunar craters. We will also demonstrate how to generate synthetic fresh lunar craters based on their power spectral densities, which will be integrated into a lunar landscape evolution model to study impact-related processes on the Moon.
