Work in progress: Space Shuttle managers today announced a 24-hour delay in the launch of Shuttle Discovery on mission STS-103. The next launch opportunity is at 8:47 p.m. Friday, Dec. 17. Shuttle engineers have requested the additional time to confirm the quality control processes for Arrowhead Products of Los Alamitos, California. Arrowhead is a vendor that provides welded propellant lines to the Shuttle Program, including main propulsion system (MPS) lines in the orbiter's aft engine compartment.

On Tuesday, the vendor's quality control personnel notified NASA of a welding flaw on a pressure line being fabricated for use on a future external tank. While Shuttle engineers have already exonerated Shuttle Discovery's external tank of any welding flaws, the ongoing evaluation will confirm the quality of the procedures used to manufacture Shuttle MPS lines. Though managers are confident in the structural integrity of Discovery's MPS lines, this evaluation is being conducted as a precaution.

Launch managers at KSC are not working any significant issues and stand ready to support tomorrow's launch opportunity. The countdown clock will hold at the T-11 hour mark and a decision to begin tanking operations will be made at about noon tomorrow. Weather officials indicate a 60 percent chance that weather will prohibit tomorrow's launch. The primary concern is thick cloud layers and the possibility of coastal showers.
