Members of the media view the Radiological Control Center (RADCC) at NASA's Kennedy Space Center in Florida during a tour regarding safety equipment and procedures for the upcoming launch of the Mars Science Laboratory (MSL) mission.
The MSL spacecraft includes a multi-mission radioisotope thermoelectric generator (MMRTG) that will generate the power needed for the mission from the natural decay of plutonium-238, a non-weapons-grade form of the radioisotope. MSL's components include a car-sized rover, Curiosity, which has 10 science instruments designed to search for signs of life, including methane, and help determine if the gas is from a biological or geological source. Launch of MSL aboard a United Launch Alliance Atlas V rocket is targeted for Nov. 26 from Space Launch Complex 41 on Cape Canaveral Air Force Station.
