KENNEDY SPACE CENTER, FLA. - The Mars Exploration Rover 1 (MER-1) is seen in the foreground after the science boom was deployed.  Set to launch in Spring 2003, the MER Mission will consist of two identical rovers designed to cover roughly 110 yards each Martian day over various terrain. Each rover will carry five scientific instruments that will allow it to search for evidence of liquid water that may have been present in the planet's past.  The rovers will be identical to each other, but will land at different regions of Mars.  The first rover has a launch window opening May 30, and the second rover a window opening June 25.

CAPE CANAVERAL, Fla. -- Workers unload a container holding the back shell, 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.

CAPE CANAVERAL, Fla. -- Astronaut Rick Sturckow flies weather reconnaissance in a Shuttle Training Aircraft over NASA's Kennedy Space Center in Florida to assess conditions before space shuttle Endeavour returns to Earth for the final time. Weather was observed "go" and Endeavour glided to a stop on the Shuttle Landing Facility's Runway 15 at 2:35 a.m. EDT, bringing an end to the STS-134 mission.    STS-134 delivered the Alpha Magnetic Spectrometer-2 (AMS) and the Express Logistics Carrier-3 (ELC-3) to the International Space Station. AMS will help researchers understand the origin of the universe and search for evidence of dark matter, strange matter and antimatter from the station. ELC-3 carried spare parts that will sustain station operations once the shuttles are retired from service. STS-134 was the 25th and final flight for Endeavour, which has spent 299 days in space, orbited Earth 4,671 times and traveled 122,883,151 miles. Photo credit: NASA/Tony Gray KSC-2011-4173

CAPE CANAVERAL, Fla. -- In the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, the fairing acoustic protection (FAP) system lining the inside of the Atlas V payload fairing for NASA's Mars Science Laboratory (MSL) mission is in view as the fairing is lifted into a vertical position.  The FAP protects the payload by dampening the sound created by the rocket during liftoff.  The fairing has been uncovered, and preparations are under way to clean it to meet NASA's planetary protection requirements.  At left is the other half of the fairing, still uncovered.    The fairing will protect the spacecraft from the impact of aerodynamic pressure and heating during ascent.  Although jettisoned once the spacecraft is outside the Earth's atmosphere, the fairing must be cleaned to the same exacting standards as the laboratory to avoid the possibility of contaminating it. MSL's components include a compact car-sized rover, Curiosity, which has 10 science instruments designed to search for evidence on whether Mars has had environments favorable to microbial life, including the 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 planned for Nov. 25 from Space Launch Complex 41 on Cape Canaveral Air Force Station.

This photomosaic of Triton, assembled from 14 individual frames, shows the great variety of its surface features.  At the bottom of the image are remnants of the south polar cap, containing 'dark'  streaks generally aligned towards the northeast (upper right in the image).  Even though these are darker than other features on Triton, they reflect nearly ten times as much light as the surface of the Earth's moon.  North of the cap, in the western (left) half of the disk is the region which has been informally dubbed the 'cantaloupe' terrain.  Small dimples with upraised rims and shallow central depressions dot the area.  Long fractures have opened allowing some icy material to ooze up and form a central ridge.  These criss-cross the region and extend into parts of the polar cap region.  Towards the south this terrain has a light covering of frost.  Running east to the limb of Triton, just north of the polar cap, is an area of smooth plains and low hills which is the most densely cratered region seen.  In the northeast (upper right) of this image are plains which show evidence for extensive resurfacing, including possible extrusions of flowing material onto the surface.  This region also contains two large smooth areas reminiscent of the maria of the Earth's moon which were formed by large-scale volcanic flooding.  Near the eastern (right) limb of Triton are three darker gray markings with sharply defined brighter borders.  These are unlike anything else seen in the solar system, and their origin is not yet understood. ARC-1989-A89-7061

CAPE CANAVERAL, Fla. -- Xenon lights illuminate space shuttle Endeavour's unfurled drag chute as the vehicle rolls to a stop on the Shuttle Landing Facility's Runway 15 at NASA's Kennedy Space Center in Florida for the final time. Main gear touchdown was at 2:34:51 a.m. EDT, followed by nose gear touchdown at 2:35:04 a.m., and wheelstop at 2:35:36 a.m. On board are STS-134 Commander Mark Kelly, Pilot Greg H. Johnson, and Mission Specialists Mike Fincke, Drew Feustel, Greg Chamitoff and the European Space Agency's Roberto Vittori.      STS-134 delivered the Alpha Magnetic Spectrometer-2 (AMS) and the Express Logistics Carrier-3 (ELC-3) to the International Space Station. AMS will help researchers understand the origin of the universe and search for evidence of dark matter, strange matter and antimatter from the station. ELC-3 carried spare parts that will sustain station operations once the shuttles are retired from service. STS-134 was the 25th and final flight for Endeavour, which has spent 299 days in space, orbited Earth 4,671 times and traveled 122,883,151 miles. Photo credit: NASA/Tony Gray KSC-2011-4175

Cape Canaveral, Fla. -- At the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, technicians use an overhead crane to move the aeroshell, a component of NASA's Mars Science Laboratory (MSL), to a spin stand for testing. The aeroshell consists of the backshell which carries the parachute and several components used during later stages of entry, descent and landing, and the spacecraft's heat shield.          MSL's components include a compact car-sized rover, Curiosity, which 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.

CAPE CANAVERAL, Fla. -- In the high bay of the RTG storage facility at NASA's Kennedy Space Center in Florida, Department of Energy contractor employees remove the external and internal protective layers of the shipping cask enclosing the multi-mission radioisotope thermoelectric generator (MMRTG) for NASA's Mars Science Laboratory mission.    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.     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.     MSL's components include a compact car-sized rover, Curiosity, which has 10 science instruments designed to search for evidence on whether Mars has had environments favorable to microbial life, including chemical ingredients for life.
