Christy (@christycraters) is a planetary geologist currently working on her PhD at Western University, Canada, focusing on impact cratering products and processes. With former experience in Mars spacecraft operations as a HiRISE Downlink Specialist, and a former geologist at the Arizona Geological Survey, Christy has a background in terrestrial as well as planetary geology. Her current field site is the Ries Impact Structure (Germany), where she studies the mineralogy and other aspects of the ejecta deposits. Impact craters provide a window into the subsurface of planetary bodies, with the largest structures exhuming tens of kilometers of any available rock, water, and ice. The ejecta deposits are the result of that exhumation, which redistributes this material across the surface and forms new materials under intense heat and pressure. The deposits at the Ries Impact Structure are of particular interest to her research as they represent analogies to similar impact-generated deposits on Mars. Earth-Mars comparative studies allow researchers like Christy an avenue to extrapolate past Mars climate and habitability, soil production, and subsurface volatile availability.
