CAPE CANAVERAL, Fla. – In the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center in Florida, technicians work beneath NASA's Mars Science Laboratory (MSL) mission aeroshell, (containing the compact car-sized rover Curiosity), which has been mated to the cruise stage. The cruise stage provides solar power, thrusters for navigation, and heat exchangers to the rover during its flight from Earth to Mars. The rover Curiosity has 10 science instruments 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. Launch of MSL aboard a United Launch Alliance Atlas V rocket is scheduled for Nov. 25 from Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida.
