Spacewalker Scott Parazynski, anchored to a foot restraint on the end of Discovery's boom, works to repair a damaged solar array on the International Space Station. During the 7-hour, 19-minute spacewalk, Parazynski cut a snagged wire and installed homemade stabilizers dubbed "cufflinks," designed to strengthen the damaged solar array's structure and stability in the vicinity of the damage.

Astronaut Doug Wheelock (out of frame), mission specialist, assisted from the truss by keeping an eye on the distance between Parazynski and the array. Once the repair was complete, flight controllers on the ground successfully completed the deployment of the array.
