Dust Storms and Dust Devils between Syria Planum and Claritas Fossae (Enhanced Natural Colors; credits: NASA/MGS/MSSS)

Caption NASA originale:"This color-enhanced composite of Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) wide angle images shows dust-raising events (small dust "storms" and a few very large dust devils) in the Syria/Claritas Region around 2 p.m. MLT on May 21, 2003. The Region is southwest of the Labyrinthus Noctis, near 14°S, 108°W. Sunlight illuminates the scene from the left; winds were blowing from the west/southwest when the picture was taken. This composite was constructed from a full-resolution (240 meters per pixel) red wide angle image and a much lower resolution (7,5 Km per pixel) blue wide angle image acquired at the same time".
