163 Impact Cratering Processes Across the Solar System: In Memory of Dr. Bevan M. French
Session focuses on the nature of impact craters and their influence on planetary geologic evolution. We solicit contributions on aspects of impact crater formation, ejecta, shock processes, geochemical and mineralogical signatures, modeling, and geologic implications; comparison among planetary bodies.

Abstract
Here we report preliminary findings from the Impact Crater and Associated Research United States (ICAARUS) Workshop, which was funded by the Barringer Crater Company and held in June 2025. This workshop brought together scientists from multiple subdisciplines within impact cratering research to assess the state of the field, identify areas of interdisciplinary collaboration, and brainstorm actionable steps to enable the community to pursue these and other research opportunities. The workshop followed an ‘ideas lab’ style where goal setting and discussion were participant-driven. The discussion centered around a common theme of supporting the impact cratering community in four areas: (1) maintaining and expanding research and collaboration opportunities, (2) on-ramping and bolstering the next generation of researchers, (3) developing a more robust public-facing presence, and (4) establishing self-organization to promote community development. Science themes, such as impact melt formation and evolution, and material properties under impact conditions, were identified as areas of research that could promote broad participation within the field and across subdisciplines. Community development activities like creating an impact newsletter and restarting Bridging the Gap workshops could help strengthen interdisciplinary connections. We acknowledge that only a subset of the cratering community could attend the workshop and look forward to increasing engagement from the broader community.
