NASA Mars Reconnaissance Orbite Images – August 10, 2011

o Cerberus Fossae Fractures http://hirise.lpl.arizona.edu/ESP_021464_1900

These fractures have acted as a conduit for the release of water and lava onto the surface relatively recently in Martian geologic history.

o Troughs and Wind Features of the Tharsis Region http://hirise.lpl.arizona.edu/ESP_021527_1960

Graben of different orientations criss-cross each other here, indicating that the terrain was stretched in different directions at different times.

o A Forest of Channels on the South Polar Layered Deposits http://hirise.lpl.arizona.edu/ESP_023164_1020

The regularity of these features may suggest something about the thickness of ground ice deep below the surface.
