MARS RECONNAISSANCE ORBITER HIRISE IMAGES

o Flow Structures in Noctis Region Trough	
  http://hirise.lpl.arizona.edu/ESP_020313_1720

  The tectonic forces that opened this canyon also disrupted the crust 
  in this location and led to the formation of many isolated blocks of 
  rock with intervening valleys.

o Enigmatic Mound on the Crater Floor on Margaritifer Terra	
  http://hirise.lpl.arizona.edu/ESP_023264_1680

  The origin of this mound on a crater floor was not clear from prior 
  image coverage, so we targeted HiRISE to take a closer look.

o The Gemstone Floor of Noctis Labyrinthus	
  http://hirise.lpl.arizona.edu/ESP_023359_1710

  The smooth light-toned deposits on the floor of Noctis Labyrinthus 
  may contain a form of hydrated silica, perhaps opal, which is a gemstone.

o Striking Impact

  Newly-formed impact craters on Mars are found and dated by comparing images 
  before and after the impact and looking for changes.

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.
