Named after the Roman god of war, Mars has fascinated people for thousands of years. Did you know that . . .
- A martian year is 687 earth days, almost twice as long as a year on earth.
- Mars's biggest valley, Valles Marineris, is four times as deep as the Grand Canyon!
- Scientists think that Mars, now rocky and barren, once had an ocean, rivers, and a thicker atmosphere.
- The first robot ever to explore the surface of Mars is only about the size of a child's toy wagon.
