MARS RECONNAISSANCE ORBITER HIRISE IMAGES
May 16, 2012

o A Youthful Crater in the Cydonia Colles Region

  Just what makes a Martian crater youthful, in a geologic sense?
  Very old craters tend to have eroded rims and can have plenty of
  material that's filled in the floor.

o Monitoring Dune Gullies

  Remarkably, we have learned that the gullies form primarily or entirely
  during seasons when there is carbon dioxide frost on the ground.

o Streamlined Landforms near the Cerberus Fossae

  One of the earliest observations of Mars that indicated that water once
  flowed across its surface was the presence of large streamlined landforms.

o Sand Ripples at a Potential Landing Site
  http://hirise.lpl.arizona.edu/ESP_026726_1790

  Landing of the surface of Mars requires extensive planning and imaging
  reconnaissance. This terrain west of Aeolis Planum is being considered
  as landing site for a future Mars mission.
