Risky spacewalk will test astronaut's skill

From CNN.com - Technology:

NASA officials hustled Friday to finish planning a riskier-than-usual spacewalk to save a ripped solar wing at the international space station. Astronaut Scott Parazynski will attempt a repair to the damaged solar array on Saturday. Repairing the solar panel, one of two power problems plaguing the station, is the top priority for the final days of shuttle Discovery's mission. NASA says one of the problems must be solved before any more shuttles can fly to the orbiting outpost. The space agency is focusing on the wing because further damage could force officials to junk the important -- and expensive -- piece of equipment. The agency hopes to send veteran spacewalker Scott Parazynski to conduct the repairs on Saturday. It will be a difficult and potentially dangerous mission for Parazynski, who runs the risk of being shocked as he tries to fix the damaged panel.
