CAPE CANAVERAL, Fla. -- In the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, preparations are under way to stow the robotic arm on the Mars Science Laboratory (MSL) rover, Curiosity. The arm will hold and maneuver instruments that will help scientists analyze Martian rocks and soil. Much like a human arm, the robotic arm has flexibility through shoulder, elbow, and wrist joints that permit the arm to extend, bend, and angle precisely against rocks and soil to grind away layers, take microscopic images and analyze their elemental composition. At the end of the arm is a hand-like structure, the turret, for holding various tools that can spin through a 350-degree turning range. A United Launch Alliance Atlas V-541 configuration will be used to loft MSL into space. Curiosity’s 10 science instruments are designed to search for evidence on whether Mars has had environments favorable to microbial life, including chemical ingredients for life. The unique rover will use a laser to look inside rocks and release its gasses so that the rover’s spectrometer can analyze and send the data back to Earth. MSL is scheduled to launch Nov. 25 from Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida. For more information, visit http://www.nasa.gov/msl.
