MARS RECONNAISSANCE ORBITER HIRISE IMAGES

o Basin in the West Candor Chasma Layered Deposits

  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

  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

  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.
