MARS RECONNAISSANCE ORBITER HIRISE IMAGES

o Martian Honeycomb Hideout

  The most striking aspect of this image is the honeycomb-like 
  pattern of the dunes.

o Defrosting of Dunes with Large Gullies	
  http://hirise.lpl.arizona.edu/ESP_024103_2565

  The gullies at this site are particularly large, which is intriguing, 
  suggesting that this site be monitored to see if stages of gully 
  formation or details of activity can be observed.

o A Sinuous Ridge South of Moreux Crater	
  http://hirise.lpl.arizona.edu/ESP_024224_2190

  This observation shows a sinuous ridge that may be an inverted stream. 
  Streams can be inverted if they are made of stronger material than their 
  surroundings.

o Looking for Changes in Colorful Aureum Chaos

  Although Mars has a thin atmosphere, the wind is nevertheless strong 
  enough to move some sand dunes and ripples, collectively termed "bedforms."
