Curiosity rover's features
NASA's latest Mars rover, Curiosity, is set to touch down on Mars in an awesome landing at approximately 1:31 AM Eastern Daylight Time on Monday, August 6, 2012. Read my Geekend post for more details about the rover and where to watch the live broadcast.
This NASA image of Curiosity highlights some of the main features of the rover, including the cameras and devices on the mast and the arm (labeled MAHLI). As you can see, Curiosity has several redundant systems, including duplicate hazard cameras ("HazCams") on the front and rear, dual NavCams, and dual MastCams. Curiosity is also six-wheel-drive, so it should be able to avoid getting stuck like its predecessor, Spirit.
