Scott Parazynski inspects his work during a risky seven-hour and 19-minute spacewalk earlier this month to repair a damaged solar array on the International Space Station (ISS). With his feet secured to the end of a 50-foot boom attached to the station's robotic arm, the Discovery shuttle astronaut cut a snagged guide wire and affixed jerry-rigged fasteners to stabilize tears suffered when the panel was unfurled in space after being moved from one side of the station to the other. The torn panel had jeopardized plans for providing enough energy to the growing station.
