MARS RECONNAISSANCE ORBITER HIRISE IMAGES
March 13, 2013

o Recent Gully Activity on Mars
  http://hirise.lpl.arizona.edu/ESP_020661_1440

  Changes in gullies were first seen in images from the Mars
  Orbiter Camera in 2006, and studying such activity has been a
  high priority for HiRISE.

o A Crater Gets Torn in Half

  Planetary surfaces can be very complex and record many different
  events and modifications. Scientists try to reconstruct the history
  of these surfaces by looking to see how features overlap.

o Colorful Gully Walls in Terra Sirenum
  http://hirise.lpl.arizona.edu/ESP_030667_1395

  Gullies are found on many slopes in the middle and near-polar latitudes
  of Mars. Although they contain no liquid water today, whether and how
  much water may have been involved in their formation is a matter of
  considerable debate.

o Eastern Rim of Endeavour Crater
  http://hirise.lpl.arizona.edu/ESP_030872_1775

  Endeavor Crater is a large impact crater formed on Mars billions of years
  ago. Erosion and burial have filled in the depression and reduced the rim
  to a broken-up ring of hills made of rock that is older than the surrounding plains.

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.
