Technicians at the Payload Hazardous Servicing Facility have lowered NASA's Mars Science Laboratory MSL rover.

Technicians, at the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, have lowered NASA's Mars Science Laboratory (MSL) rover, known as Curiosity, onto the high bay floor where its instrument mast and science boom will undergo deployment testing.

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.
