This is an image of Mars taken from orbit by the Mars Reconnaissance
Orbiter's Mars Color Imager (MARCI). The Red Planet's polar ice-cap is in
the middle of the image. Captured in this image is a 37,000
square-kilometer (almost 23,000 miles) dust storm that moved
counter-clockwise through the Phoenix landing site on Oct 11, 2008, or Sol
135 of the mission.
Viewing this image as if it were the face of a clock, Phoenix is shown
as a small white dot, located at about 10 AM. The storm, which had
already passed over the landing site earlier in the day, is located at
about 9:30 AM.
