NASA Mars Reconnaissance Orbiter HiRISE Images – May 2, 2012

– Three Dust Devils http://hirise.lpl.arizona.edu/ESP_025985_2160

There are also bright lines present, representing the tracks of dust devils that have already passed through this region.

– Colorful Uplifted Rocks http://hirise.lpl.arizona.edu/ESP_026388_2300

Central peaks on Mars have some of the most diverse and distinctive rock types.

– Layered Bedrock in Nili Fossae Region http://hirise.lpl.arizona.edu/ESP_026570_2025

The differing colors indicate different rock types of alteration. The darkest patches of ground probably consist of volcanic sand that is trapped in relative low areas.

– A Flow Margin in Phlegra Dorsa http://hirise.lpl.arizona.edu/ESP_026738_2080

The Phlegra Dorsa region consists of ancient hills that have been surrounded and partially buried by flows from the Cerberus Fossae to the south.
