KENNEDY SPACE CENTER, Fla. (AP) - NASA officials say the problem
with a fuel tank sensor that scrubbed today's shuttle launch has been plaguing them since April.
They hope to try for a launch on Saturday.
Today's glitch involved one of four hydrogen fuel sensors. It gave a false reading that the tank was empty. Even though the other three sensors were working, Deputy Shuttle Program Manager Wayne Hale says that didn't meet the safety criteria.
The faulty sensor could actually have catastrophic results if it caused the shuttle's engines to cut out too early or too late.
