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.

KENNEDY SPACE CENTER, FLA. - At NASA's Family & Community Mars Exploration Day held in Cape Canaveral, Fla., students look at a remote-controlled model of the Mars Exploration Rover. The event informed students and the general public about Florida's key role as NASA's "Gateway to Mars" and offered an opportunity to meet with scientists, engineers, educators and others working Mars exploration missions. The Mars Exploration Rovers are being prepared for launch this spring aboard Boeing Delta II rockets from the Cape Canaveral Air Force Station. They will land on Mars and start exploring in January 2004. KSC-03pd0514

KENNEDY SPACE CENTER, Fla. - The Mars Exploration Rover 2 (MER-2) undergoes testing in the Payload Hazardous Servicing Facility. MER-1 and MER-2, their aeroshells and landers will undergo a full mission simulation before being integrated. After spin balance testing, each spacecraft will be mated to a solid propellant upper stage booster that will propel the spacecraft out of Earth orbit. Approximately 10 days before launch they will be transported to the launch pad for mating with their respective Boeing Delta II rockets. The rovers will serve as robotic geologists to seek answers about the evolution of Mars, particularly for a history of water. The rovers are identical to each other, but will land at different regions of Mars. Launch of the first rover is scheduled for May 30 from Cape Canaveral Air Force Station. The second will follow June 25. KSC-03pd0673

KENNEDY SPACE CENTER, FLA. - In the Payload Hazardous Servicing Facility, the cruise stage is mated to the Mars Exploration Rover 2 (MER-2) entry vehicle. The cruise stage includes fuel tanks, thruster clusters and avionics for steering and propulsion. NASA's twin Mars Exploration Rovers are designed to study the history of water on Mars. These robotic geologists are equipped with a robotic arm, a drilling tool, three spectrometers, and four pairs of cameras that allow them to have a human-like, 3D view of the terrain. Each rover could travel as far as 100 meters in one day to act as Mars scientists' eyes and hands, exploring an environment where humans can't yet go.

KENNEDY SPACE CENTER, FLA. - A closeup of the cruise stage to be mated to the Mars Exploration Rover 2 (MER-2) entry vehicle. The cruise stage includes fuel tanks, thruster clusters and avionics for steering and propulsion. NASA's twin Mars Exploration Rovers are designed to study the history of water on Mars. These robotic geologists are equipped with a robotic arm, a drilling tool, three spectrometers, and four pairs of cameras that allow them to have a human-like, 3D view of the terrain. Each rover could travel as far as 100 meters in one day to act as Mars scientists' eyes and hands, exploring an environment where humans can't yet go. MER-2 is scheduled to launch June 5 as MER-A aboard a Delta rocket from Cape Canaveral Air Force Station.

When vertical, it will be lifted up the launch tower and mated to the Delta rocket (in the background) to launch Mars Exploration Rover 2. NASA’s twin Mars Exploration Rovers are designed to study the history of water on Mars. These robotic geologists are equipped with a robotic arm, a drilling tool, three spectrometers, and four pairs of cameras that allow them to have a human-like, 3D view of the terrain. Each rover could travel as far as 100 meters in one day to act as Mars scientists' eyes and hands, exploring an environment where humans can’t yet go. MER-2 is scheduled to launch June 5 as MER-A. MER-1 (MER-B) will launch June 25.
