HiRISE: Quite smoooooth
Quite smoooooth. Here in Deuteronilus Mensae, there is a smooth geologic unit overlying plains material. There are also slightly convex-up edges, polygonal patterns on the surface, and softened craters. HiRISE Picture of the Day archive. [More at links]
THEMIS: Ice-rich mantling in Utopia crater
THEMIS Image of the Day, April 16, 2019. This false-color VIS image shows a crater located in Utopia Planitia. The crater’s interior shows ample evidence for an ice-rich mantling material that has slipped and slumped away from the crater’s upraised … Continue reading

THEMIS: Gullies and floor features in Aonia Terra crater
THEMIS Image of the Day, January 17, 2019. Many large gullies dissect the rim of this unnamed crater in Aonia Terra. The inner walls and floor both show evidence of pasted-on terrain — a layer of potentially ice-rich dust. See … Continue reading
