MUNDANE MYSTERIES: Why is Mars red?

MUNDANE MYSTERIES: Why is Mars red?

After yesterday’s historic mission by NASA to land on Mars I figured we would tackle one of the most mysterious things about the planet. Why is it red?

A lot of the rocks on Mars are full of iron. So when they are exposed to air and the outdoors they tend to oxidize and get that reddish color. Same reason your bulkhead or an old bike left outside would get rusty. When the dust from the rusty rocks starts to peel off and get in the atmosphere the sky around Mars starts to look pink.

Maybe one day we will all be able to go see it up close in person!
