MARS RECONNAISSANCE ORBITER HIRISE IMAGES

o Double Layer Ejecta in an Arabia Region Crater

  After an impact, there sometimes multiple phases of material 
  that fall to the ground, creating the appearance of layered-ejecta.

o Fluvial Fan on a Crater Floor

  This observation shows a terrific fan-shaped deposit, beginning 
  where the channel enters a crater.

o Dune Composition

  Patterns of dune erosion and deposition provide insight into the 
  sedimentary history of the surrounding terrain.

o Very Fresh Impact Crater Superposing a Wrinkle Ridge in Hesperia Planum

  Wrinkle ridges are long, winding topographic highs and are often 
  characterized by a broad arch with superposed narrow asymmetric ridges.

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.
