HiRISE: Terrain near Idaeus Fossae
Terrain near Idaeus Fossae. Many valleys occur all over Mars that reveal an extensive ancient history of liquid water erosion. While these valley systems are typically now covered with fine soils and sand dunes, the overall scale and shape of … Continue reading

Rivers raged on Mars late into its history
Long ago on Mars, water carved deep riverbeds into the planet’s surface — but we still don’t know what kind of weather fed them. Scientists aren’t sure, because their understanding of the Martian climate billions of years ago remains incomplete. … Continue reading

Inverted terrain shows ancient stream-flow details
River deposits exist across the surface of Mars and record a surface environment from over 3.5 billion years ago that was able to support liquid water at the surface. A region of Mars named Aeolis Dorsa contains some of the … Continue reading

HiRISE: Cataracts in Kasei Valles
Obviously these are not the kind of cataracts that can develop in the lenses of your eyes, but large erosional scallops that form in river channels, like the Niagara Falls draining the Great Lakes of North America. Cataracts are large … Continue reading
