Mars is called the red for a reason: the amount of rusty iron that is on its own surface. Many scientists believe that there used to be life on that planet because of all the frozen water and the fact there is rusty iron all over the place. The only way iron can rust is that it has to have contact with oxygen without oxygen there is no way that it can turn rusty. There might have been air that WE could have breathed. So in the end the reason why mars is so red is because it has so much rusty iron on it that it makes it look red so if you want to look at mars closer look at a old rusty pan!
