Curiosity: the latest on NASA's newest Mars rover

Curiosity is the name of NASA's latest Mars rover, a car-sized nuclear powered robot whose lasers and sensors will hopefully help determine if the planet could ever have supported life. Launched on November 26th, 2011, the vehicle successfully touched down on August 6th, beginning its mission to send back the newest and most complete information scientists have ever gathered about Mars's climate and geology, and laying the groundwork for a future manned mission to the red planet.
