CAPE CANAVERAL, Fla. - In the Payload Hazardous Servicing Facility, or PHSF, at NASA's Kennedy Space Center in Florida, a crane lifts the Flight Support System carrier from the payload canister toward a stand in the PHSF. The carrier contains hardware for the STS-125 Hubble Space Telescope servicing mission that has been returned to the PHSF to await a new launch date for the mission. Atlantis' targeted launch on Oct. 14 was delayed when a system that transfers science data from the orbiting observatory to Earth malfunctioned on Sept. 27. The new target launch date is under review. Photo credit: NASA/Kim Shiflett KSC-08pd3252

Cape Canaveral, Fla. -- The sunrise casts a haze over the Shuttle Landing Facility and the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, where the arrival of NASA's Mars Science Laboratory (MSL) first three elements are being delivered by 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.

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.

The container, known as the "gorilla cage," protects the MMRTG and allows any excess heat generated to dissipate into the air. In the PHSF, the MMRTG temporarily will be installed on the MSL rover, Curiosity, for a fit check but 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. -- In the high bay of the Payload Hazardous Servicing Facility (PHSF) at NASA's Kennedy Space Center in Florida, spacecraft technicians from NASA's Jet Propulsion Laboratory guide the multi-mission radioisotope thermoelectric generator (MMRTG) for NASA's Mars Science Laboratory (MSL) mission on the turning fixture toward 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 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.

CAPE CANAVERAL, Fla. – The Orion crew module, stacked atop its service module, is on its way from the Payload Hazardous Servicing Facility, or PHSF, to the Launch Abort System Facility, or LASF, at NASA's Kennedy Space Center in Florida. The spacecraft for Exploration Flight Test-1 was fueled in the PHSF. Inside the LASF, the Launch Abort System will be installed around the Orion spacecraft ahead of its December flight test. Orion is the exploration spacecraft designed to carry astronauts to destinations not yet explored by humans, including an asteroid and Mars. It will have emergency abort capability, sustain the crew during space travel and provide safe re-entry from deep space return velocities. The first unpiloted test flight of the Orion is scheduled to launch atop a United Launch Alliance Delta IV Heavy rocket from Cape Canaveral Air Force Station in Florida to an altitude of 3,600 miles above the Earth's surface. The two-orbit, four-hour flight test will help engineers evaluate the systems critical to crew safety including the heat shield, parachute system and launch abort system.
