CAPE CANAVERAL, Fla. -- Repair work to space shuttle Discovery's external fuel tank begins to wrap up in the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. Technicians modified 94 support beams, called stringers, on the tank's intertank region by fitting pieces of metal, called radius blocks, over the stringers' edges. They also were re-applying foam to the modified areas of the tank. Attached to its fuel tank and two solid rocket boosters, Discovery is scheduled to roll out to Launch Pad 39A atop a giant crawler-transporter on Jan. 31. Discovery's next launch opportunity to the International Space Station on the STS-133 mission is targeted for Feb. 24.
