CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, a crawler-transporter moves under NASA's new mobile launcher (ML) support structure. The crawler will transport the ML from a construction site, north of the Vehicle Assembly Building, to the Mobile Launcher east park site. Once there, the ML can be outfitted with ground support equipment, such as umbilicals and access arms, for future rocket launches. It took about two years to construct the 355-foot-tall structure, which will support NASA's future human spaceflight program. The base of the launcher is lighter than space shuttle mobile launcher platforms so the crawler-transporter can pick up the heavier load of the tower and a taller rocket.

CAPE CANAVERAL, Fla. -- This panoramic view shows NASA's new mobile launcher, or ML, support structure standing tall at NASA's Kennedy Space Center in Florida. It took about two years to construct the launcher in the Mobile Launcher Park site, north of the Vehicle Assembly Building, or VAB. The 355-foot-tall structure will support NASA's future human spaceflight program. The base of the launcher is lighter than space shuttle mobile launcher platforms so the crawler-transporter can pick up the heavier load of the tower and a taller rocket. The next step will be to add ground support equipment, such as umbilicals and access arms, for future rocket launches. For information on NASA's future plans, visit www.nasa.gov.

CAPE CANAVERAL, Fla. -- This panoramic image shows the Pegasus Barge carrying the Space Shuttle Program's last external fuel tank, ET-122, through the Port Canaveral locks on its way to the Turn Basin at NASA's Kennedy Space Center in Florida. Once docked, the tank will be offloaded from the barge and transported to the Vehicle Assembly Building (VAB). The tank traveled 900 miles by sea, carried in the barge, from NASA's Michoud Assembly Facility in New Orleans. Once inside the VAB, it eventually will be attached to space shuttle Endeavour for the STS-134 mission to the International Space Station targeted to launch Feb. 2011. STS-134 currently is scheduled to be the last mission in the shuttle program. The tank, which is the largest element of the space shuttle stack, was damaged during Hurricane Katrina in August 2005 and restored to flight configuration by Lockheed Martin Space Systems Company employees.

CAPE CANAVERAL, Fla. – Huge cranes are employed in building the new mobile launcher behind NASA Kennedy Space Center's Vehicle Assembly Building for the Constellation Program's Ares rockets. The ML will be the base to launch the Orion crew exploration vehicle and the cargo vehicle. The base is being made lighter than space shuttle mobile launcher platforms so the crawler-transporter can pick up the added load of the 345-foot tower and taller rocket. When the structural portion of the new mobile launcher is complete, umbilicals, access arms, communications equipment and command/control equipment will be installed.

CAPE CANAVERAL, Fla. – At NASA's Kennedy Space Center in Florida, preparations are made to lift the fourth section of the tower onto a new mobile launcher, or ML, being constructed to support the Constellation Program. The tower will be approximately 345 feet tall when completed and have multiple platforms for personnel access. The ML is being built at the mobile launcher park site area north of Kennedy's Vehicle Assembly Building. The launcher will provide a base to launch the Ares I, designed to transport the Orion crew exploration vehicle, its crew and cargo to low Earth orbit. The base is being made lighter than space shuttle mobile launcher platforms so the crawler-transporter can pick up the heavier load of the tower and taller rocket.

CAPE CANAVERAL, Fla. – At NASA's Kennedy Space Center in Florida, the fourth section of tower is lifted toward three sections already secured to a new mobile launcher, or ML, being constructed to support the Constellation Program. The tower will be approximately 345 feet tall when completed and have multiple platforms for personnel access. The ML is being built at the mobile launcher park site area north of Kennedy's Vehicle Assembly Building. The launcher will provide a base to launch the Ares I, designed to transport the Orion crew exploration vehicle, its crew and cargo to low Earth orbit.

CAPE CANAVERAL, Fla. – At NASA's Kennedy Space Center in Florida, progress on the construction of the tower on a new mobile launcher, or ML, for the Constellation Program is apparent as the seventh tower segment is balanced in position. When completed, the tower will be approximately 345 feet tall and have multiple platforms for personnel access. The construction is under way at the mobile launcher park site area north of Kennedy's Vehicle Assembly Building. The launcher will provide a base to launch the Ares I rocket, designed to transport the Orion crew exploration vehicle, its crew and cargo to low Earth orbit.
