Hardened arteries in Nili and Nilo
Water seeping through conduits and cracks in the deep subsurface rocks of Nilosyrtis and Nili Fossae left behind minerals, like hard-water deposits that collect in the plumbing of your house. (Or cholesterol in your arteries.) Then as the softer rocks … Continue reading

Lava flows resurfaced crater lakes after water was gone
Fire and water didn’t mix when it came to resurfacing basins that lie along Martian fluvial valley networks. A study of some 30 open-basin lakes (paleolakes) with floors covered by lava flows has concluded that at least these basins were … Continue reading
