Icy & Fluvial Features
Ice plains, glaciers, chaos terrain, hydrocarbon lakes, and ancient river channels.
- Cantaloupe TerrainSurface featureTriton
The strange, dimpled surface of Neptune's moon Triton, resembling the skin of a cantaloupe — a young, resurfaced landscape unlike anywhere else, imaged by Voyager 2.
- Conamara ChaosSurface featureEuropa
A region of Europa where the icy crust has broken into a jumble of tilted blocks 'rafts' set in refrozen slush — evidence that the surface interacts with the ocean below.
- Kraken MareSurface featureTitan · ≈ 1,100 km across
The largest known sea of liquid methane and ethane on Titan, near the north pole — the largest body of surface liquid in the Solar System beyond Earth.
- Ontario LacusSurface featureTitan
The largest lake in Titan's southern hemisphere, a shallow methane-ethane lake whose shoreline changes with the moon's seasons.
- Sputnik PlanitiaSurface featurePluto · ≈ 1,000 km across
The vast nitrogen-ice plain that forms the western lobe of Pluto's bright 'heart'. Its ice slowly churns in convection cells and flows like a glacier, keeping the surface young.
- Jezero CraterSurface featureMars
A crater that once held a lake, with a well-preserved river delta at its rim. The Perseverance rover is caching samples here in the search for signs of ancient life.
- Kasei VallesSurface featureMars
One of the largest outflow channels on Mars, carved by catastrophic floods of water that burst from the Tharsis region billions of years ago.
