MARS RECONNAISSANCE ORBITER HIRISE IMAGES
August 29, 2012

o Changing Mars	
  http://hirise.lpl.arizona.edu/ESP_016700_2075

  This observation shows dramatic differences from earlier images 
  and evidence for two distinct processes of Martian wind erosion.

o Colorful Surface Near Nili Fossae

  Much of the surface shows a chaotic mix of colors, but the northern 
  impact crater exposes distinct layers.

o Exploring the Mounds in the Chryse Region	
  http://hirise.lpl.arizona.edu/ESP_027339_2060

  The mounds in this observation may have been formed by a process 
  called "diapirism," where material from the depth is raised above 
  the surface.

o Light-Toned Rocks Exposed along Coprates Chasma	
  http://hirise.lpl.arizona.edu/ESP_027973_1650

  Some of the brighter rocks could be minerals that formed when 
  basaltic rock was altered by water flowing deep underground a long 
  time ago before the chasma opened up.

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.
