Autumn Dust Storm

April 24, 2012
Autumn on the martian northern plains means clouds and dust storms. As autumn got underway in early May 2003, large dust storms began to form on the northern plains and sweep their way eastward--and sometimes southward--bringing colder air down from the north polar cap, now shrouded in darkness and clouds. This early autumn view, assembled from Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) daily global images, shows an eastward-moving dust storm on the plains north of Cydonia and western Arabia Terra. The storm is nearly as big as the continental United States are wide, from west to east. In this image, north is toward the top, east to the right, and sunlight illuminates the scene from the lower left. MGS MOC Release No. MOC2-405, 28 June 2003
