o Small Crater within Pollack Crater Containing Light-Toned Material   

  This observation shows a small crater in within the much larger Pollack Crater containing light-toned material. 

o Lava Against an Impact Crater in Elysium Planitia     

  In places where we see smaller ridges in the lava, they have steep faces that retain less dust and look rocky. 

o Looking for Changes in Dust Drifts West of Alba Mons   

  This image was intended to search for surface changes after three Mars years in a dust-covered region west of the Alba Mons volcano. 

o Frosted Impact Crater in Late Northern Winter   

  Changing gullies have so far been documented only in the Southern Hemisphere, where a greater thickness of carbon dioxide frost forms in the winter.
