Weather is serious business - both here on earth and on our planetary neighbor.
Winds frosts and thaws are dynamic processes that tell us much about a planet's past, present and future. Mars is no exception. The U.S. Mars Global Surveyor spacecraft began orbiting the Red Planet almost two years ago, and since then has been mapping Mars and observing its weather. This is a season when Mars' weather changes significantly. As it goes from northern summer toward southern springtime and summer in the south, we're seeing large changes in the nature of cloud activity.
