MARS RECONNAISSANCE ORBITER HIRISE IMAGES
April 18, 2012

o Active Dune Gullies in Kaiser Crater

  Gullies remain an interesting feature to study on Mars, especially
  because we are still learning about their formation and what processes
  still act on them.

o Disappearing Boulder Tracks
  http://hirise.lpl.arizona.edu/ESP_026055_1985

  This follow-up image to an earlier observation shows that the smaller
  dark tracks are gone, and the larger ones have faded considerably.

o Late Springtime Defrosting of Northern Dunes
  http://hirise.lpl.arizona.edu/ESP_026226_2565

  Every winter, dunes and other surfaces at these northern latitudes are
  coated with several tens of centimeters of carbon dioxide frost and ice,
  plus a minor amount of water frost.

o Landslides in an Impact Crater

  The many large landslides inside Valles Marineris are well known, but
  there are also landslides elsewhere on Mars.
