o Mysterious Color-Changing Dust Devil Track

  Suction created by the air rotating in a whirlwind removes a 
  thin layer of light-colored dust from the Martian surface, leaving 
  behind dark lines in its path.

o Possible Newest Segment of Cerberus Fossae

  Floods of water and lava are thought to have emanated from the 
  larger fossae nearby, perhaps forming the Athabasca channel and 
  later filling it with lava.

o The Millipedes of Mars?

  Dunes are particularly suited to comprehensive planetary studies 
  because they are abundant over a wide range of elevations and terrain types.

o Lobate Flow Features in the Northwest Hellas Rim

  Lobate features such as these are indicative of viscous flow, 
  reminiscent of terrestrial glaciers and have long-been interpreted as 
  evidence for subsurface ice.

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.
