Ever since mankind has been aware of it, the planet Mars has been our solar system's chief object of wonder, mystery and sci-fi suspicion. The so-called "red planet" had a fiery reputation that lasted until we began to learn the far less shocking truth: Mars is a barren, dead planet, and no Martians with ray guns live there. Still, though, the planet has much to teach us about how a once-alive planet dies, and the mystery of what the old Mars looked like continues to intrigue scientists and amateur astronomers alike. In this gallery, we'll take a closer look at the fourth rock from the sun.
