Now it is possible to see what the martian atmosphere will do for at least two-thirds of a second martian year, because the Extended Mission will run into April 2002. This picture captures two dust storms, each large enough to cover Arizona or New Mexico. One is located near the lower left, the other at the lower right. Hellas Planitia is the dominant elliptical feature just below the center of the picture.
North is up and sunlight illuminates the area from the upper left.
The approximately 500 kilometer-wide circular feature just above the center is the crater Huygens.
