How much does Mars polar caps disappear in spring and summer?  Do they
move,or just evaporate? If you took a picture of the ice caps from
summer to summer how much change would there be? Comparing time frames
can give us lots of information.  Mars equator must be its hottest area.
What is the difference in temp of the ice caps to the equator? Is the
South Pole colder than the North Pole?  Does sand and dust cover the
pole areas?         Bert
