Impact-Induced Dust Avalanches
ESP_058514_2140  Science Theme: Impact Processes
HiRISE has been imaging new dark features discovered by MRO’s Context Camera, which are mostly new impact sites. In this scene we see what appears to be a new impact cluster and, extending downhill from the craters,new dark slope streaks.

These slope streaks are formed by dry dust avalanches. We’ve also seen large new dust avalanches associated with new impacts at previous locations.
