MARS RECONNAISSANCE ORBITER HIRISE IMAGES
January 15, 2014

o Dunes on the Rim of the Hellas Impact Basin	
  http://hirise.lpl.arizona.edu/ESP_034101_1385

  Sand dunes like these in this image have been observed to 
  creep slowly across the surface of Mars through the action of the wind.

o Recent Volcanism in Valles Marineris	
  http://hirise.lpl.arizona.edu/ESP_034131_1670

  The possibility of recent volcanism inside Valles Marineris was first 
  proposed decades ago based on Viking orbiter images.

o Looking for Salts on Mars	
  http://hirise.lpl.arizona.edu/ESP_034309_1485

  In this observation, chlorides have a bright appearance and are covered 
  by other dark materials.

o Fissure near Cerberus Fossae with Tectonic Morphologies	
  http://hirise.lpl.arizona.edu/ESP_034716_1875

  The linearity of the volcanic vent in this observation, along with evidence 
  of lava flow from the vent, suggests control by combined volcano-tectonic 
  processes.

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.
