Rover Heads to Mars

NASA's first Mars Explorer rover roared into space on Tuesday on board a Boeing Delta II rocket after two days of delays to poor weather, and some last minute glitches with ground tracking stations. The newly named rover, "Spirit", will take seven months to reach Mars. Once it does arrive, the six-wheeled Spirit will land on the surface of the Red Planet, and begin exploring the surface searching for evidence of past water. The second rover, "Opportunity", was originally expected to launch on June 25, but it might be also be delayed because Spirit's launch was pushed back.
