Abstract

A Few Facts about Mars • Temperatures can range from -225°F to 70°F on the surface • Mars's atmosphere is around 100 times thinner than Earth's • Water cannot survive as a liquid on the surface, but it can be found in frost, brines (salty water), minerals, the polar caps, and sub-surface ice! • Dust devils and wind on Mars cleaned off dusty solar panels on the Mars Exploration Rovers Spirit and Opportunity, allowing a greater amount of electricity to be generated • Mars is approximately half the size of Earth • Mars has the highest mountain (Olympus Mons) and the deepest canyon (Valles Marineris) in the Solar System
