NASA's Mars Science Laboratory (MSL) rover, known as Curiosity, arrives at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida aboard an Air Force C-17 cargo plane. Also aboard is the rocket-powered descent stage that will fly the rover during the final moments before landing on Mars.
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 from Cape Canaveral Air Force Station in Florida Nov. 25 with a window extending to Dec. 18 and arrival at Mars Aug. 2012.
