New images of the Martian south polar cap and a crater in
the Northern Hemisphere show seasonal changes taking place in
each region as seen from NASA’s Mars Global Surveyor spacecraft,
currently orbiting Mars.

It is summer at Mars’ South Pole and the residual ice cap
has shrunk to its minimal size but is still covered with carbon
dioxide frost. It is winter in the North, and the rims of the
Lomonosov Crater are draped with an icy frost beneath low-lying
ground fog.

The Global Surveyor images are available at , or .
