It would be pretty tough to live on Mars. It"s cold, dry, and the conditions are harsh. The planet"s average temperature is about –81 degrees Fahrenheit, but it can get as low as –243 at the poles. But with many canyons, extinct volcanoes, and ice caps, it"s beautiful to look at from afar. Most photos of the red planet highlight its rusty color, caused by high levels of iron oxide.
