Mars from Hubble, January 2008

 Occupying the upper left quadrant is the bright red of Tharsis, and at upper center and right is the dark blob of Acidalia. Below Acidalia, a bright extension from the Tharsis region is Chryse planitia, where both Viking 1 and Pathfinder landed. Below that, at the center of the disk, is a darker region made of Solis Lacus at left, Aurorae Sinus at center, and on the right-hand edge of the disk, Sinus Meridiani, where Opportunity still roves. A bright blob called Argyre is at the bottom of the disk, and over all of it is printed wispy white clouds, made of water vapor.
