Two Hubble Space Telescope storm watch images from late June and early September.
Two Hubble Space Telescope storm watch images from late June and early September 2001 offer dramatically contrasting views of the Martian surface. At left, the onset of smaller "seed" storms can be seen near the Hellas basin (lower right edge of Mars) and the northern polar cap. A similar surface view at right, taken over two months later, shows the fully developed extent of the obscuring global dust storm.
