Another awesome Martian avalanche
This is amazing! The HiRISE camera on the Mars Reconnaissance Orbiter caught another avalanche on Mars.

Dunes of Mars
via nasa.gov
From the NASA website:
Dunes of sand-sized materials have been trapped on the floors of many Martian craters. This is one example, from a crater in Noachis Terra, west of the giant Hellas impact basin. The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter captured this view on Dec. 28, 2009.
The dunes here are linear, thought to be due to shifting wind directions. In places, each dune is remarkably similar to adjacent dunes, including a reddish (or dust colored) band on northeast-facing slopes. Large angular boulders litter the floor between dunes.

Victory, Victoria!
Very cool picture of the crater Victoria taken by the HiRISE camera on Mars Reconnaissance Orbiter. Click on the blog link above for more information about the crater.
Note: on the far left of the picture, you can see wheel tracks from the Mars rover Opportunity which spent a year exploring the crater.
