MARS RECONNAISSANCE ORBITER HIRISE IMAGES
June 13, 2012

o Which Crater Came First?
  http://hirise.lpl.arizona.edu/ESP_020190_1690

  This image shows two craters, both approximately the same diameter 
  but quite different in appearance otherwise. Which one might have 
  formed first?

o Sinuous Ridges in Aeolis Planum

  The eroded ridges are located in a trough, while the well-preserved 
  ridges are at higher elevation.

o Wavy-Looking Layers in the North Polar Layered Deposits

  These layers near the North Pole of Mars probably record global 
  climate changes, similar to ice ages on Earth.

o Bright Material along the Floor of a Trough in Noctis Labyrinthus

  This HiRISE image shows an example of the bright material commonly 
  found along the floors of some of the Noctis Labyrinthus troughs.

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.
