Exploratour - The Atmosphere of Mars
Temperatures
This picture shows how cold the surface of Mars can be. The picture shows the surface of Mars and the temperatures at the surface. The purple regions are the coldest, about -170 degrees F (140K), while the yellow areas are the warmest at about 17 degrees F (270K). The surface of Mars may often become warmer than 17 degrees; it can be 30 degrees F or more. 30 degrees is still cold, however! The temperatures show that surface is either near freezing or well below freezing. Freezing temperatures may have something to do with the thin atmosphere by preventing evaporation.
