CAPE CANAVERAL, Fla. (AP) - The international space station's newly installed solar wings are about to get stretched.
Astronauts aboard the orbiting station-shuttle complex will start unfurling the two wings late Friday morning, by remote control.
NASA managers say they expect to be on pins and needles throughout the five-hour procedure. That's because the wings could get hung up or some of the panels could stick together. That's happened before on previous flights.
On Thursday, a pair of spacewalking astronauts successfully hooked up the $300 million framework that holds the folded-up wings. The spacewalk lasted six hours - record time for a job like this.
Two more spacewalks are scheduled while shuttle Discovery is docked to the space station. The shuttle is due to depart next week.
