MARS RECONNAISSANCE ORBITER HIRISE IMAGES
May 23, 2012

o Breccia with Large Clasts
  http://hirise.lpl.arizona.edu/ESP_025600_1735

  In this beautiful image there appears to be a breccia layer, or a
  layer composed of rock fragments embedded in a finer material.

o In the Transition Zone
  http://hirise.lpl.arizona.edu/ESP_025675_2255

  Erosion and the formation of small scarps reveal a multitude of layers
  within the subsurface.

o A Trough within Ladon Basin
  http://hirise.lpl.arizona.edu/ESP_026416_1620

  This trough, and others around the perimeter of the basin, were probably
  produced during the gradual sinking of the materials here.

o Expanded Craters on Icy Terrain
  http://hirise.lpl.arizona.edu/ESP_026510_2310

  One interpretation of the expanded craters is that a group of small impacts,
  probably secondary craters from a much larger primary crater, exposed the
  clean, shallow ice in this region.

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.
