– Layered Material Cut by a Valley Connected to East Jezero Crater

This image shows layered bedrock composed of light- and intermediate-toned materials.

– Active Sand Abrasion in the Northern Polar Region of Mars

The large dune field which surrounds Mars’ North Polar cap is actively being modified by the wind, with dunes moving at rates of a meter or more per year.

– Streaks on the North Polar Layered Deposits

These streaks may be formed by winds blowing bright water frost over the surface, removing frost from the surface, or blowing dark material over the frost.

– Pluvo Point

Although we can clearly see the bright area in this image, it isn’t due to frost or ice at this time of year.
