HiRISE: Impact-induced dust avalanches
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 … Continue reading

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

Medusae Fossae Formation: single largest source of dust on Mars
The dust that coats much of the surface of Mars originates largely from a single thousand-kilometer-long geological formation near the Red Planet’s equator, scientists have found. A study published in the journal Nature Communications found a chemical match between dust … Continue reading
