HiRISE images for November 25, 2009

The following new images taken by the High Resolution Imaging Science Experiment (HiRISE) on the Mars Reconnaissance Orbiter spacecraft are now available:

• Winter View of Dunes
  Dunes within a crater on Mars are visible in this HiRISE image. This crater is located in the southern hemisphere where it was winter at the time this image was taken.
• Martian Dichotomy Boundary
  This observation crosses over a part of the hemispheric dichotomy boundary on Mars which separates low-lying northern plains from older southern highlands.
• Wall Rock and Light-Toned Layering in Candor Chasma
  While the canyon walls that define Valles Marineris appear dark and blocky, the interior of the canyons can sometimes be filled with light-toned rocks that appear layered.
• Valles Marineris Wall Rock
  This image captures a small part of the northern wall of Valles Marineris, the largest canyon in the solar system.
• Gullies and Flow Features on Crater Wal
  This HiRISE image shows a sample of the variety and complexity of processes that may occur on the walls of Martian craters, well after the impact crater formed.
