HiRISE: Icy erosion
This image shows an interesting collection of kilometer-scale craters with flat and smooth floors. The craters themselves may be the result of secondary impacts, craters caused by debris from a distant larger impact. Since then, the surface has been significantly … Continue reading

HiRISE: Coming and going of ice
Like Earth’s water table, Mars has an ice table. Sometimes, the ice table coincides with the ground’s surface as it does here. The knobby, pitted terrain is caused when ice is deposited and then sublimates over and over again. This … Continue reading
