The extreme conditions and exotic materials on the surfaces of outer solar system bodies – such as the icy satellites, small bodies, and Kuiper Belt Objects – result in unique surface processes not commonly observed on rocky terrestrial planets. As the scientific community considers the in-situ exploration of these worlds, increasing collaboration between those who focus on landscape scales and those who study processes at the scale of a landed robotic vehicle will continue to increase in importance. To gather these different scientific communities together, we invite contributions ranging in focus from comparative planetology and remote sensing, to laboratory analogs, instrumentation and experiments, to theoretical and numerical modeling. We intend for this session to foster more collaboration between these communities, so that we may continue to explore the commonality of surface processes, from the grain to landscape scales, that affect these bodies, despite their dispersion across the solar system.
