NASA Mars Reconnaissance Orbiter HiRISE Images – August 28, 2013
o Basin in the West Candor Chasma Layered Deposits http://hirise.lpl.arizona.edu/ESP_017741_1745
Wind is a powerful, erosive force, transporting fine-grain sediments that can shape topography and expose darker material underneath the surface.
o Oxbows and Cutoffs in Idaeus Fossae

As rivers age they can meander and occasionally these meanders get so pronounced that the river cuts off these curving loops at their narrow end leaving them as isolated as oxbow lakes.
o Breaching a Crater Rim in Tartarus Montes http://hirise.lpl.arizona.edu/ESP_029072_2040
In this observation, we can see a small notch in a crater rim with a well-formed channel, where lava flowed. Did the crater fill to the level of the lava outside?
o Migrating and Static Sand Ripples on Mars http://hirise.lpl.arizona.edu/ESP_032616_1275
Having operated at Mars for more than seven years, MRO and the HiRISE camera continue to make new discoveries. One of these is that many sand dunes and ripples are moving, some at rates of several meters per year.

Information about the Mars Reconnaissance Orbiter is online at http://www.nasa.gov/mro. The mission is managed by NASA’s Jet Propulsion Laboratory, a division of the California Institute of Technology, for the NASA Science Mission Directorate, Washington, D.C. Lockheed Martin Space Systems, of Denver, is the prime contractor and built the spacecraft. HiRISE is operated by the University of Arizona. Ball Aerospace and Technologies Corp., of Boulder, Colo., built the HiRISE instrument.
