MARS RECONNAISSANCE ORBITER HIRISE IMAGES
February 1, 2012

o The Floor of Toro Crater	
  http://hirise.lpl.arizona.edu/ESP_025067_1970
 
  Toro Crater may have experienced hydrothermal alteration, 
  producing diverse minerals.

o Crater with Gullies on a Central Structure	
  http://hirise.lpl.arizona.edu/ESP_025082_2295

  The formation of channels on the debris aprons supports 
  the hypothesis that these sediments were transported down  
  the gullies and then deposited onto the aprons by flowing water.

o Active Erosion in Pasteur Crater	
  http://hirise.lpl.arizona.edu/ESP_025372_2000

  This image shows knobs and bluffs that are being actively eroded 
  by the Martian wind.

o Another Well-Preserved Impact Crater	
  http://hirise.lpl.arizona.edu/ESP_025450_1595

  When seen at full resolution, almost all craters on Mars show 
  some modification such as subsequent smaller impacts, and 
  downslope movement of material on steep slopes.

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.
