United KingdomThe European Space Agency's Mars Express has captured images of dozens of active dust devils in the Mamers Valles region of Mars. Dust devils on Mars form when the surface warms in sunlight, creating swirling columns of air that lift dust into the atmosphere. These phenomena are similar to terrestrial dust devils but much larger, reaching heights of up to 8 kilometers and speeds of 45 meters per second. The Mars Express uses its High Resolution Stereo Camera to detect movement by combining images from multiple camera channels.
