Discovery External Tank Repairs Underway

Engineers Analyze Data On All 108 Stringers

Technicians working on space shuttle Discovery's external fuel tank in the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida began repairs Monday on three support beams, called stringers, that recently were detected to have small cracks on their tops.

Engineers at various NASA centers continue to analyze data from testing and X-ray type image scans collected during the past week of all 108 stringers on the outside of the external tank's intertank section. The image scans showed four small cracks on three stringers on the opposite side of the tank from Discovery. Managers decided Thursday to have those cracks repaired in a similar fashion to repairs made on cracks on two stringers found after Discovery's Nov. 5 launch attempt.

The repair work is estimated to take 2-3 days. Any further work will be evaluated thoroughly during the week after additional data and analysis are reviewed.

Technicians at NASA's Kennedy Space Center in Florida will also begin modifications to 34 additional stringers on space shuttle Discovery's external fuel tank on Tuesday. Crews will fit pieces of metal, called radius blocks, over the tops of the stringers located at the external tank's thrust panel area to increase the structural support of the stringers. The thrust panel areas are located at the attachment points between the tank and the solid rocket boosters, which see the most stress during the flight into orbit.

The work is expected to take approximately one week. Teams currently are performing scans on all of the tank's stringers using a backscatter device, which bounces radiation off the tank allowing engineers to see below the foam insulation. Engineers at various NASA centers continue to analyze testing and imaging data. Managers will meet again Thursday to determine whether radius block modifications are needed on the remaining stringers.

The next available launch date for Discovery's STS-133 mission to the International Space Station remains Feb. 3 at the opening of a window that extends through Feb. 10.
