Mars Rover Launch

On Saturday, a NASA rocket carrying a rover dubbed "Curiosity" started its eight-and-a-half-month journey to Mars.

            The rover is scheduled to land on August 6, 2012.

            Once it arrives, the rover will collect rocks and soil to see if there are signs of life on the Red Planet.

            Our John Zarrella was at Kennedy Space Center in Florida for the launch and sent us this BackStory.
