MARS RECONNAISSANCE ORBITER HIRISE IMAGES

o Two-Color Dunes in Meridiani Terra	
  http://hirise.lpl.arizona.edu/ESP_033483_1805

  Why are these dunes different colors? Sand on Mars is typically 
  dark in tone, as it commonly derived from volcanic rocks like lava 
  flows.

o Slumping Terraces on a Crater Wall

  This slumped terrace, a result of the crater formation process, 
  gives the crater a concentric ringed appearance.

o A Heart in Ascraeus Mons	
  http://hirise.lpl.arizona.edu/ESP_035807_1885

  What is this strange-looking feature? HiRISE scientists first 
  noticed it in images from the Context Camera and acquired this 
  picture to investigate more closely.

o Opportunity Rover's Winter Work at Murray Ridge
  http://hirise.lpl.arizona.edu/ESP_035909_1775
 
  This new image of Opportunity was acquired as a "ride-along" with 
  the CRISM instrument also onboard MRO, to help give better details 
  of the topography here.

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.
