ISS Astronauts Plan 4th Spacewalk to Stow Jammed Solar Array
Astronauts from the Shuttle Discovery today will conduct a fourth spacewalk to fold a solar array on the International Space Station that became jammed when they tried to stow it.
The array, a concertina-like structure that generates solar power, was part of a temporary electrical system on the ISS that astronauts replaced with a permanent one. While they pulled the so-called P6 port array back enough to allow a new one to begin rotating and tracking the sun, the retraction wasn't complete.
The space station's broken again. The funny part about this is that they're going to fix it by "pulling on guidelines and pushing hinges" and "if necessary, the spacewalkers will shake the panel."
