Atlantis astronaut Pat Forrester (upper left) works in this image from NASA TV attached to the end of the International Space Station's robot arm as he helps retract the P6 solar array June 13, 2007. Forrester and fellow spacewalker Steve Swanson will also prepare the newly installed S3/S4 truss for operation and finish the retraction of the starboard P6 solar array to set the stage for a future shuttle crew to relocate the P6 from atop the space station to the end of the Port 5 truss.
