The extreme conditions and exotic ices on the surfaces of outer solar system bodies result in unique landscapes not commonly observed on rocky bodies. Sublimation of volatile ices controls the evolution of many icy world landscapes and has given rise to planetary climates, while tectonic and eruptive processes evolve ice shells, interacting with potentially habitable subsurface oceans. The many interrelations between these processes are only beginning to reveal themselves; as exploration of the outer solar system proceeds at a progressively rapid rate, the complexities of these worlds will continue to grow. To piece together these exotic planetary landscapes, will require investigations that incorporate increasingly diverse scientific techniques and collaboration between the many sub-communities studying icy worlds – from those who study comets, to Arrokoth, and everything in between. We invite contributions ranging in focus from comparative planetology and remote sensing, to laboratory and analog studies, to theoretical and numerical modeling.
