The left image shows the Tharsis region on the left limb, Solus Lacus and Valles Marinaris in the center, Margaritifer Terra, Aurora Sinus in the central disk, Acidalia to the upper right, and Sinus Meridiani disappearing into evening haze on the right limb. The central image shows Sinus Meridiani and Sebaeus Sinus in the center, with Syrtis Major disappearing around the right limb and Margaritifer Terra emerging on the left limb. The righ image shows Syrtis major central on the disk, the Hellas Basin below it, Tyrhenna Terra and Hesperium to the lower right of it, and Sebaeus Sinus to the left of it and Sinus Meridiani emerging around the left limb. The three images cover about 270 degrees of the circumferece of the planet. The south polar cap has decreased in size between the images.
