This Week’s HiRISE Picture Shows Sulfates in Aram Chaos
Written by Marko on June 22, 2008
This picture is from Aram Chaos crater in Mars. It was taken last month by HiRISE camera of MRO-probe. The crater was named Aram Chaos because of the broken formations of the surface.
Scientists believe the crater was formed when the material under the surface dissappeared. Lowest parts of the crater contain dark sand which is coloured blue in the picture. On can also see the dunes formed by the sand right next to steep walls.
“Sulfates have been detected in the cliff walls in some areas within Aram Chaos, as well as hematite. It has been suggested that these materials were deposited within a lake setting“, was said in HiRISE project website.
