OPS4

Icy moons and ocean worlds across the Solar System preserve a wide variety of geological and geomorphological features that reflect the interaction between surface evolution and internal activity. Tectonics, resurfacing, cryovolcanism and geomorphology provide constraints on the structure, thermal evolution, and dynamics of ice shells, subsurface oceans, and deep interiors. This session welcomes contributions focused on the geology and surface processes of ocean worlds, including remote sensing, geological mapping, structural and tectonic analyses, geomorphology, stratigraphy, surface-atmosphere interactions, as well as interior dynamics explored through gravity field analysis, numerical and theoretical modelling. We encourage studies based on spacecraft observations, remote sensing datasets, laboratory experiments, and comparative planetology. Relevant targets include Europa, Enceladus, Titan, Ganymede, Callisto, Triton, Pluto, and other candidate ocean worlds. Contributions using data from past and ongoing missions, as well as studies supporting future exploration by Europa Clipper, JUICE, Dragonfly, UOP are particularly encouraged.
