Atlantis Tanking Indicates Possible Valve Leak but Should not Affect Launch Date

Payload Readied for Trip to the Pad as Tanking Test Wraps Up, NASA

"During the tanking test, the main fuel valve for Atlantis' No. 3 space shuttle main engine recorded temperatures below normal levels, indicating a possible liquid hydrogen leak. Teams isolated the engine and continued to fuel Atlantis with no issues and temperatures returned to normal readings. Technicians can gain access to the engine area once it is cleared from tanking test operations, and engineers will evaluate any necessary work on the fuel valve. If the valve needs to be replaced, managers expect that the work could be done early next week at the pad and still support Atlantis' July 8 target launch date."
