Active High-Latitude Dune-Gullies On Mars
Gully and defrosting activity have been visible here along the edge of a dune field, along with blocks of frost. Observations of the same area help us check for repeat […]

Defrosting Dunes On Mars
This image shows a field of sand dunes in the Martian springtime while the seasonal carbon dioxide frost is sublimating into the air. This sublimation process is not at all […]
