MARS RECONNAISSANCE ORBITER HIRISE IMAGES

o Lava Flow Constricted between Topographic Obstacles	
  http://hirise.lpl.arizona.edu/ESP_020580_2035

  This constriction seems to have disrupted the flow and produced a 
  platy-ridged surface on the down-flow side of the constriction point.

o Brain-Coral Texture on Crater Floor	
  http://hirise.lpl.arizona.edu/ESP_023649_1360

  This crater floor has a hummocky texture ("brain-coral"-like), and 
  curved structures, possibly from glacial-like flow.

o Gullies with Varied Shapes on a Crater Wall	
  http://hirise.lpl.arizona.edu/ESP_023665_1410

  A couple of gullies in this image are unusual because a segment in the 
  middle becomes wider than the upslope segment, and then narrows again downslope.

o The Eastern Floor of Aram Chaos	
  http://hirise.lpl.arizona.edu/ESP_024266_1830

  The interplay between the dunes, eroded landforms and the various other 
  light and dark-toned materials provides clues to the relative ages of the 
  geologic processes and the nature of the materials.

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.
