Aram Chaos

Acquired on April 1, 2018, this image from NASA’s Mars Reconnaissance Orbiter shows Aram Chaos, a 280 kilometer-diameter ancient impact crater that lies within in the Southern Highlands of Mars. Uplifted blocks of light-toned layers, composed largely of the iron-oxide hematite and water-altered silicates, indicate that this crater once held a lake.

“Alluvial Fans in Saheki Crater, Mars

Alluvial fans are gently-sloping wedges of sediments deposited by flowing water. Some of the best-preserved alluvial fans on Mars are in Saheki Crater, an area that has been imaged many times previously.”
