Rolling Martian Avalanche Greets the Spring
Springtime on Mars means the thaw of carbon dioxide ice in the northern hemisphere. And when the dry ice goes, the party's over for any trapped debris that then goes tumbling down Martian cliffs in spectacular images such as this. The Mars Reconnaissance Orbiter (MRO) has been snapping similar photos for a few years, but the dynamic image still stands out among red-planet landscapes that may have remained relatively unchanged for millions of years. Some other signs of change come from the dust devils that spin their merry way across the Martian surface.
