CAPE CANAVERAL, Fla. (AP) - An electrical problem has cropped up again aboard space shuttle Discovery and could jeopardize Wednesday's launch.
The trouble appears to be with a backup controller for one of the shuttle's three main engines. NASA ordered last-minute reviews and hurriedly scheduled a mid-afternoon meeting of top managers.
A NASA spokeswoman says it's too soon to know whether Wednesday afternoon's planned launch will remain on track. Discovery's final launch originally was scheduled for Monday, but was delayed by shuttle gas leaks.
The controller was sluggish early Tuesday morning. But after turning a circuit breaker and switch on and off several times, everything seemed to be fine. Later, voltage irregularities were noted.
