CAPE CANAVERAL, Fla. -- Workers unload a container holding the cruise stage, one of the first three elements for NASA's Mars Science Laboratory (MSL) that arrived at NASA Kennedy Space Center's Shuttle Landing Facility aboard an Air Force C-17 cargo plane. The cruise stage, back shell and heat shield, the first flight elements to arrive for the MSL mission, were taken to the Payload Hazardous Servicing Facility (PHSF) located in the KSC Industrial Area to begin processing. The Curiosity rover will arrive next month. 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.

ORLANDO, Fla. – NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif., unveiled an inflatable, full-size model of the Mars Science Laboratory mission's Curiosity rover at the "For Inspiration and Recognition of Science and Technology," or FIRST, competition at the University of Central Florida in Orlando. The rover is scheduled to launch from Cape Canaveral Air Force Station in Florida aboard an Atlas V later this year. FIRST, founded in 1989, is a non-profit organization that designs accessible, innovative programs to build self-confidence, knowledge and life skills while motivating young people to pursue academic opportunities. The robotics competition challenges teams of high school students and their mentors to solve a common problem in a six-week timeframe using a standard kit of parts and a common set of rules.

CAPE CANAVERAL, Fla. -- In the high bay of the Payload Hazardous Servicing Facility (PHSF) at NASA's Kennedy Space Center in Florida, the multi-mission radioisotope thermoelectric generator (MMRTG) for NASA's Mars Science Laboratory (MSL) mission is attached to the MMRTG integration cart. The cart will be used to install the MMRTG on the Curiosity rover for a fit check. The rover is on an elevated work stand, at right. The MMRTG then will be removed and installed on the rover for launch at the pad. The MMRTG will generate the power needed for the mission from the natural decay of plutonium-238, a non-weapons-grade form of the radioisotope. Heat given off by this natural decay will provide constant power through the day and night during all seasons. Curiosity, MSL's car-sized rover, 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. Waste heat from the MMRTG will be circulated throughout the rover system to keep instruments, computers, mechanical devices and communications systems within their operating temperature ranges. Launch of MSL aboard a United Launch Alliance Atlas V rocket is planned for Nov. 25 from Space Launch Complex 41 on Cape Canaveral Air Force Station.

CAPE CANAVERAL, Fla. -- In the high bay of the Payload Hazardous Servicing Facility (PHSF) at NASA's Kennedy Space Center in Florida, the multi-mission radioisotope thermoelectric generator (MMRTG) for NASA's Mars Science Laboratory (MSL) mission is attached to the MMRTG integration cart. The cart will be used to install the MMRTG on the Curiosity rover for a fit check. The wheels of the rover appear to stick out on either side of the cart. The MMRTG will be installed on the rover for launch at the pad. The MMRTG will generate the power needed for the mission from the natural decay of plutonium-238, a non-weapons-grade form of the radioisotope. Heat given off by this natural decay will provide constant power through the day and night during all seasons. Curiosity, MSL's car-sized rover, 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. Waste heat from the MMRTG will be circulated throughout the rover system to keep instruments, computers, mechanical devices and communications systems within their operating temperature ranges. Launch of MSL aboard a United Launch Alliance Atlas V rocket is planned for Nov. 25 from Space Launch Complex 41 on Cape Canaveral Air Force Station.

CAPE CANAVERAL, Fla. -- A crane is positioned over the multi-mission radioisotope thermoelectric generator (MMRTG) for NASA's Mars Science Laboratory (MSL) mission in the high bay of the RTG storage facility (RTGF) at NASA's Kennedy Space Center in Florida. Preparations are under way to lift the mesh container, known as the "gorilla cage," from the support base on which the MMRTG is resting. The cage protects the MMRTG during transport and allows any excess heat generated to dissipate into the air. The MMRTG is returning to the RTGF following a fit check on MSL's Curiosity rover in the Payload Hazardous Servicing Facility (PHSF). The MMRTG will generate the power needed for the mission from the natural decay of plutonium-238, a non-weapons-grade form of the radioisotope. Heat given off by this natural decay will provide constant power through the day and night during all seasons. MSL's components include a compact 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. Waste heat from the MMRTG will be circulated throughout the rover system to keep instruments, computers, mechanical devices and communications systems within their operating temperature ranges. Launch of MSL aboard a United Launch Alliance Atlas V rocket is targeted for Nov. 25 from Space Launch Complex 41 on Cape Canaveral Air Force Station.
