Another update as of 4pm:
Discovery's astronauts have temporarily stopped the effort to retract a solar array at the International Space Station because the outpost is now flying on the dark side of Earth.
A little more than 40 percent of the array has been folded up, clearing the way for a new solar wing delivered in September to rotate like a Ferris wheel, tracking the sun to maximize electrical output.
At least 12 of 31 sections of two accordion-like solar blankets that make up the array had to be folded up to provide clearance for the new wing to be put into operation. Fourteen were folded up before problems with guidewires prompted the astronauts to abort the retraction.
Flight directors now are trying to decide whether to try to extend the array's telescoping mast again so another attempt to fully retract the array can be made.
Shuttle commander Mark Polansky suggested extending the array until the guidewires are taut, and then retracting the blankets one section at a time.
Flight directors are hesitant. Extending the arrays more than two sections and then failing to retract the blankets would leave the panel in a position where the new wing would make contact with it as it rotated.
A decision on a course of action is upcoming.
Thanks! here's hoping a solar wind gust don't blow 'em for a loop.. ;-)
