NASA Mars Reconnaissance Orbiter HiRISE Images September 14, 2011

o Banded Features http://hirise.lpl.arizona.edu/ESP_023144_1850

What are the terraces/bands? Expressions of layered rock? Shorelines?

o Dunes in Western Arabia Terra http://hirise.lpl.arizona.edu/ESP_023145_1935

Dunes are particularly suited to comprehensive planetary studies because they are abundant over a wide range of elevations and terrain types.

o Colorful Rocks in Terra Sabaea http://hirise.lpl.arizona.edu/ESP_023274_1545

This region of the ancient Southern highlands has been shaped by tectonics: faulting and folding of bedrock units.

o A Channel Cut into an Impact Crater http://hirise.lpl.arizona.edu/ESP_023825_1855

What is preserved here is one step in the process that has erased many other craters in Elysium Planitia as lava filled craters and other topographic lows.
