Challenging EVA Ahead

NASA: Spacewalk will have ‘higher risk than usual’, USA Today

“Astronaut Scott Parazynski, one of NASA’s most experienced spacewalkers, will face grave risks and nerve-wracking challenges Saturday when he is scheduled to fix a damaged solar panel on the International Space Station. Among the dangers Parazynski could encounter: potential electrical shock, sharp objects that could puncture his spacesuit and a long journey back to the safety of the station.”

“NASA worked furiously Thursday to plan a spacewalk to fix the ripped solar wing at the international space station, hoping to solve the problem before the shuttle Discovery undocks. The agency wanted spacewalking astronauts to tackle the job Friday but had to push back the outing to Saturday to give officials on the ground more time to fine-tune the repair plan.”
