MARS RECONNAISSANCE ORBITER HIRISE IMAGES
April 10, 2013

o Megabreccia on the Floor of an Impact Crater
  http://hirise.lpl.arizona.edu/ESP_023099_1545

  "Megabreccia" is a term we use to describe jumbled, fragmented
  blocks of rock larger than 1 meter across.

o Ridges and Grooves That Wave and Buckle on a Valley Floor
  http://hirise.lpl.arizona.edu/ESP_026414_2205

  Scientists have long suspected these features are associated
  with some ancient climate that had prevailed in this latidunal
  region.

o Bright Tracks from Bouncing and Rolling Boulders
  http://hirise.lpl.arizona.edu/ESP_031103_1405

  Where did the boulders come from? Maybe they fell off of the
  steep upper cliffs of the crater, although we don't see any
  new bright features there that point to the source.

o Raindrops of Sand in Copernicus Crater
  http://hirise.lpl.arizona.edu/ESP_031221_1315
 
  The dark features here look like raindrops, but are actually
  sand dunes.
