Shuttle Endeavour won't set sail on its final flight before next Tuesday, May 10, at the earliest as Kennedy Space Center teams work to repair an electrical problem that scrubbed last Friday's launch attempt.
NASA had hoped a second attempt might be possible as soon as Sunday, but determined it would take about two more days than originally thought to ready the shuttle for another countdown.
"It became apparent Monday that more time was required," said Allard Beutel, a KSC spokesman.
Friday's launch scrubbed when heaters on a fuel line feeding part of the shuttle's hydraulic power system failed to turn on, a problem that could have led to a fire during flight.
