MARS RECONNAISSANCE ORBITER HIRISE IMAGES
August 29, 2012

o Changing Mars
  http://hirise.lpl.arizona.edu/ESP_016700_2075

  This observation shows dramatic differences from earlier images
  and evidence for two distinct processes of Martian wind erosion.

o Colorful Surface Near Nili Fossae
  http://hirise.lpl.arizona.edu/ESP_019753_2000

  Much of the surface shows a chaotic mix of colors, but the northern
  impact crater exposes distinct layers.

o Exploring the Mounds in the Chryse Region
  http://hirise.lpl.arizona.edu/ESP_027339_2060

  The mounds in this observation may have been formed by a process
  called "diapirism," where material from the depth is raised above
  the surface.

o Light-Toned Rocks Exposed along Coprates Chasma
  http://hirise.lpl.arizona.edu/ESP_027973_1650

  Some of the brighter rocks could be minerals that formed when
  basaltic rock was altered by water flowing deep underground a long
  time ago before the chasma opened up.
