Shuttle Launch Delayed

Aug. 3, 2007 — -- The Shuttle Endeavour will launch a day later than scheduled, NASA officials told ABC News Friday.

Bad weather has delayed the shuttle processing so much that Endeavour won't be ready to launch by Tuesday. Specifically, weather slowed down replacement and testing of the shuttle's pressure valve.

Instead, the shuttle is now scheduled to launch Wednesday at 6:23 p.m. EDT.

In recent weeks, the Endeavour has encountered several glitches, including a cabin leak and O ring sealing issues, a problem that contributed to the Challenger crash.

Recently, NASA has faced public relations problems after a report was released last week that claimed astronauts were intoxicated during liftoff.
