The red planet

The fourth planet from the sun, Mars is one of our closest neighbors yet it remains a mystery. There is strong evidence that water once flowed on the planet, but what happened to make it disappear? Is there life there? So many questions, and our quest to learn more about the red planet is just beginning. As NASA's Mars rover continues to feed our curiousity about the red planet, we can admire it from afar. (Text: Katherine Butler)
