MARS RECONNAISSANCE ORBITER HIRISE IMAGES
March 12, 2014

o Ejecta in Excess

  When impact craters are formed, the material that once
  resided in the subsurface is blown upward and outward
  creating what's called an "ejecta blanket."

o Craters within Craters

  Because the material is still brighter than the surrounding
  surface, darker dust settling out of the atmosphere has not
  had time to cover it up, so this crater is fairly recent.

o A Complex Valley Network Near Idaeus Fossae

  Many valleys occur all over Mars that reveal an extensive ancient
  history of liquid water erosion.

o Dramatic Dune Destination

  The especially bright patches are due to seasonal frost that is
  accumulating as this hemisphere approaches winter.

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.
