Near the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, a crane places on the ground one of the trusses, T4, to build the new mobile launcher for the Constellation Program. The new mobile launcher will be the base for the Ares rockets 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. Photo credit: NASA/Jim Grossmann
