The TTCR panel was subsequently folded up, covered and secured by Williams and another spacewalking astronaut during her previous space station assignment.

Williams and Hoshide teamed for spacewalks on Aug. 30 and Sept. 5 to replace a failing main bus switching unit on the station’s solar power truss, a troublesome repair. The experience seemed to pay off as Williams and Hoshide fell behind schedule while working with the intricate plumbing connections of the cooling system.

The spacewalkers are scheduled to return to Earth with cosmonaut Yuri Malenchenko aboard their Soyuz 31 mission capsule on Nov. 19.
