NASA agrees to Wednesday shuttle launch, Houston Chronicle
"NASA's shuttle managers decided Wednesday to launch the space shuttle Discovery next Wednesday for a two-week mission to the International Space Station. The decision to fly was reached after the managers spent most of the day studying engineering tests and computer simulations involving a critical fuel valve that cracked on a flight in November. Top space agency officials will meet Friday to review the decision."
