These views from above the Martian pole were assembled from mosaics of three sets of images and projected to appear as if from above. This series captures the seasonal retreat of the polar cap from its greatest extent of the year (October, 1996) at 60 degrees N latitude through (January, 1997) early Spring, to (March, 1997) early summer on Mars.
