NASA Mars Reconnaissance Orbiter HiRISE Images – August 3, 2011

o The Western Edge of a Layered Mound in Juventae Chasma http://hirise.lpl.arizona.edu/ESP_020470_1755

The CRISM instrument on MRO has detected high sulfates at the base of this mound, and the resolution power of HiRISE gives us a better look at the area’s morphology.

o Striated Highlands near Claritas Rupes http://hirise.lpl.arizona.edu/ESP_020551_1545

These striated highlands are probably the result of what is termed “mass wasting” when material higher up collapses and flows downslope.

o Crater Rim with Bedrock Layers and Gullies http://hirise.lpl.arizona.edu/ESP_022999_1335

This observation reveals some of the materials that have largely filled the crater.

o Slope of Gale Crater above MSL Landing Site http://hirise.lpl.arizona.edu/ESP_023034_1755

It is possible that hydrothermal deposits formed here in association with the creation and cooling of Gale Crater billions of years ago.
