MARS RECONNAISSANCE ORBITER HIRISE IMAGES
May 23, 2012

o Breccia with Large Clasts	
  http://hirise.lpl.arizona.edu/ESP_025600_1735

  In this beautiful image there appears to be a breccia layer, or a 
  layer composed of rock fragments embedded in a finer material.

o In the Transition Zone	
  http://hirise.lpl.arizona.edu/ESP_025675_2255

  Erosion and the formation of small scarps reveal a multitude of layers 
  within the subsurface.

o A Trough within Ladon Basin	
  http://hirise.lpl.arizona.edu/ESP_026416_1620

  This trough, and others around the perimeter of the basin, were probably 
  produced during the gradual sinking of the materials here.

o Expanded Craters on Icy Terrain	
  http://hirise.lpl.arizona.edu/ESP_026510_2310

  One interpretation of the expanded craters is that a group of small impacts, 
  probably secondary craters from a much larger primary crater, exposed the 
  clean, shallow ice in this region.

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.
