MARS RECONNAISSANCE ORBITER HIRISE IMAGES
July 18, 2012

o Flows in Hellas Planitia
  http://hirise.lpl.arizona.edu/ESP_025925_1420

  The floor of Hellas includes the lowest elevations on Mars
  and some of the strangest landscapes.

o Gully Monitoring on Crater Slopes in Terra Sirenum
  http://hirise.lpl.arizona.edu/ESP_027343_1410

  The possible role of seasonal frost in gully formation along
  with the association of polygonal terrain with these and other
  gullies has garnered considerable interest.

o Frosted Gully Landforms
  http://hirise.lpl.arizona.edu/ESP_027647_1395

  In the Martian winter, frost--mostly carbon dioxide--can build
  up in the gullies, especially on the cold slopes that face the pole.

o A Fading Impact Crater
  http://hirise.lpl.arizona.edu/ESP_027806_1700

  This cluster of craters formed quite recently from a weak impactor
  that broke apart in Mars' thin atmosphere before smashing into the surface.
