The Rover Gets Strong-Armed |
|
The Mars Science Laboratory rover will sport the biggest, toughest robotic arm the red planet's ever seen! This super-limb must lift 34 kilograms (almost 75 pounds) of instruments to reach out and test martian rocks and soil, which may hold clues about whether Mars could have supported life.

Spirit Takes a Peek at Her Belly |
|
A new image of Spirit's underbelly is helping engineers assess the rover's current state and plan her escape from soft soil. The panoramic mosaic of multiple images was taken by the microscopic imager instrument at the end of Spirit's robotic arm--the first time that imager has been used to assess the underside and wheels of the rover.
