Welder Jerry Goudy (left), with United Space Alliance, and his backup Jack Weeks, with Marshall Space Flight Center - Boeing, are ready to begin welding the minute cracks on Endeavour's flow liners. Endeavour is scheduled to fly on mission STS-113 in November. The mission payload is the P1 Integrated Truss Structure, the first portside truss to go to the International Space Station, and will be attached to the central truss segment, S0, on the Station. Also additional cooling radiators will be delivered but will remain stowed until flight 12A.1.
