Explanation:
What's happened to Mars?
In 2001, Mars underwent a tremendous
planet-wide
dust storm -- one of the largest ever recorded from Earth.
To show the extent, these 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 storm.
Although this storm eventually waned, in recent days a
new
large dust storm has been taking hold of the
red planet.
