Planetary regoliths play a key role in shaping the evolution, mechanical response, and exploration of celestial bodies across the Solar System. Understanding the behaviour of regolith materials in varying gravitational, thermal, and atmospheric conditions is essential for interpreting surface processes, understanding planetary origin and evolution, and for supporting future robotic and human exploration.
This session focuses on the mechanical, geotechnical, dynamical (flow) and thermophysical properties of regolith on planetary bodies such as the Moon, Mars, asteroids, comets, and natural satellites. We welcome contributions based on laboratory experiments, numerical simulations, and theoretical analyses, in addition to studies using in-situ, remote sensing, or returned sample data and simulants.
The session aims to provide a forum for advancing our understanding of regolith physics across planetary environments and for enhancing connections between disciplines: planetary science, granular physics, and geotechnical engineering. Interdisciplinary approaches that bridge experiments, modelling, and observations are encouraged and we particularly encourage early career scientists to submit an abstract for an oral presentation.
