New Mars Images Show Polar Cap and Dust Storm

New pictures of Mars’ south polar cap and a global view of a dust storm occurring there were released Friday by the imaging team for NASA’s Mars Global Surveyor spacecraft. Marking the four-year anniversary of its arrival at Mars, Global Surveyor’s camera took a wide-angle view of the Martian south polar region on Sept. 12, 2001. Several dramatic dust storms that began a few months ago also are seen in a color image. One is located near the Martian equator, and the other is shown northwest of the Ascraeus Mons volcano.
