These side-by-side movies show how dust has engulfed Mars. They’re derived from data taken by the Mars Color Imager onboard the Mars Reconnaissance Orbiter. The view from May shows Valles Marineris chasms (left), Meridiani center, an autumn dust storm in Acidalia (top) and the early spring south polar cap (bottom). The view from July shows the same regions hidden by the dust cloud and haze that covered the planet.
