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

• Rayed Crater in Tharsis Region
  This image shows a small rayed impact crater, about 160 meters (530 feet) in diameter, in the Tharsis region in the northern hemisphere of Mars.


• Lava Stratigraphy in the Flanks of Olympus Mons
  This HiRISE image captures a small part of the giant scarp that marks the base of Olympus Mons, the largest volcano in the solar system.


• Eroded Crater Slopes in Ancient Noachis Region
  This image covers the southern slope of an old impact crater inside a larger and still older crater, in the Martian highlands.


• Changing Frost Patterns in Louth Crater
  This image shows the changing seasonal frost patterns on Louth Crater, located at latitude 70 N.


• Jointed Rocks Near Nilosyrtis Mensae
  This image shows a part of the floor of a large, heavily modified crater in the Nilosyrtis Mensae region.


• Frosted Crater Near Mars' North Pole
  This image was taken over the north polar region of Mars, just south of the layered ice cap.


• Layered Rock in Noctis Labyrinthus
  This scene is the floor of a trough in Noctis Labryinthus, a region of chaotic terrain located between the Tharsis Rise and Valles Marineris.


• Mantled Craters in Terra Cimmeria
  This image shows the intersection of two overlapping craters, although it is unknown which of the two formed first.
