The solar arrays on the P6 element of the ISS have been in space since 2000, and this was the first time they had been retracted in six years. When they were installed, they were put on top of the station.
The newer arrays, part of the P4 element, were installed in 2006 in their permanent position on the end of a long truss. The P6 element will eventually be moved outboard of P4 on the truss. The other side of the P6 solar array will be retracted on a shuttle mission in 2007 in advance of this move outboard, so managers are eager to learn the cause of the problem and how to prevent it in the future.
Solar flares
Despite the setback, astronauts Fuglesang and Curbeam will make their second spacewalk on Thursday, as planned. During their excursion, they will help rewire the ISS so that the station will have enough electrical power to add energy-intensive components, such as future laboratories.
Meanwhile, for the past two nights, flight surgeons have asked the crews to sleep in areas of the shuttle and station with additional shielding to protect them from increased solar activity and the possibility of extra radiation heading their way. The Sun released a large solar flare at 0240 GMT on Wednesday. Satellites were expected to show some minor problems, but the astronauts were not expected to be in any danger.
