This Saturday or Sunday, U.S. astronaut Scott Parazynski will make one of the most difficult and potentially dangerous spacewalks in history. Parazynski will try to fix the ripped solar wing on the International Space Station. The plan requires travel almost from one end of the station to the other, a repair procedure which were just developed and can't be rehearsed, and the need to work next to an electrically charged panel that cannot be turned off. Astronauts on the ISS have already fashioned a brace from aluminum strips to take stress off the panel's damaged hinge.
