– Ejecta in Excess

When impact craters are formed, the material that once resided in the subsurface is blown upward and outward creating what’s called an “ejecta blanket.”

– Craters within Craters

Because the material is still brighter than the surrounding surface, darker dust settling out of the atmosphere has not had time to cover it up, so this crater is fairly recent.

– A Complex Valley Network Near Idaeus Fossae

Many valleys occur all over Mars that reveal an extensive ancient history of liquid water erosion.

– Dramatic Dune Destination

The especially bright patches are due to seasonal frost that is accumulating as this hemisphere approaches winter.
