MARS RECONNAISSANCE ORBITER HIRISE IMAGES

o Recent Gully Activity on Mars

  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

  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

  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.
