MARS RECONNAISSANCE ORBITER HIRISE IMAGES

o Remnants of a Viscous Flow on Mars

  Some of the lobate flows here are pristine-looking and highly 
  reminiscent of terrestrial glaciers, whereas others appear more 
  degraded.

o Ancient Layers on Mars

  The terrain here is along the boundary between the ancient 
  highlands and the younger lowlands of Mars.

o Slope Streak Details and a New Streak

  Some people have proposed these streaks are the traces of 
  liquid water, but most scientists think that they form when 
  very thin layers of fine dust is disturbed and slides downhill.

o Colorful Layers Exposed in the Walls of an Impact Crater

  This image covers most of an impact crater about 6 to 7 kilometers 
  wide. Partway down from the crater rim is a prominent bright layer 
  of bedrock.

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.
