Sublimation-driven erosion on Hyperion: Topographic analysis and landform simulation model tests

► The lack of inter-crater plains is in part due to loss of fall back ejecta. ► Weathering and mass wasting creates honeycomb pattern of old craters. ► Fresher craters exhibit upper slopes that are still undergoing erosional retreat. ► This style of erosion is consistent with sublimation loss of topography-supporting cement.
