PASADENA, Calif. (AP) — A robotic spacecraft circling Mars has snapped the first image of a series of active avalanches near the planet's north pole, scientists said Monday.
The image, taken last month, reveals at least four avalanches of fine ice and dust breaking off from a steep cliff and settling on the slope below. The cascade kicked up massive debris clouds, with some measuring more than 590 feet across.
The landslides were spied by the Mars Reconnaissance Orbiter during a routine tracking of seasonal changes. The probe arrived at the planet in 2006.
