MARS RECONNAISSANCE ORBITER HIRISE IMAGES
August 15, 2012

o Bright and Dark Slope Streaks in Arabia Terra	
  http://hirise.lpl.arizona.edu/ESP_022405_1910

  While HiRISE has imaged slope streaks before, bright strikes 
  are not as common as dark ones, so they're of high interest.

o A Pedestal Crater in Malea Planum	
  http://hirise.lpl.arizona.edu/ESP_022787_1085

  Pedestal craters are the remnants of geologic units that have been 
  heavily eroded from the surface of Mars.

o On the Hunt for New Impact Craters	
  http://hirise.lpl.arizona.edu/ESP_027077_1785

  In this observation, we see a dark spot with a larger, rayed "blast 
  zone" that was also apparent in a Context Camera image taken in 2011,
  but not in 2009.

o Dune Migration

  In addition to migration of the dune, we will also use these repeat 
  images to look for changes in the dune shape and avalanches down the 
  slip face.

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.
