HiRISE: Dark side of dust avalanches
The dark side of dust avalanches. Changes on the Martian surface are detected by imaging the same area more than once. Here, we see several new dust avalanches on the slopes of ridges within the Olympus Mons Aureole. These changes … Continue reading

HiRISE: Bang and whoosh!
This HiRISE image captures a new, dated (within about a decade) impact crater that triggered a slope streak. When the meteoroid hit the surface and exploded to make the crater, it also destabilized the slope and initiated this avalanche. The … Continue reading
