Triumph in Orbit

Scott Parazynski, supported by a cast of astronuts on the shuttle Discovery and the International Space Station (ISS) plus experts on the ground, pulled off one of the most difficult feats in the history of human spaceflight. In a complex seven-hour spacewalk, Parazynski anchored an extension boom on the ISS' robot arm, snipped tangled wires, and attached braces improvised on the space station to repair a 33.5-meter-long solar wing that was damaged last Tuesday. Parazynski, a doctor specializing in emergency medicine before he became an astronaut, surely never cured a more important patient. NASA can now proceed with the next launch in December, using the shuttle Atlantis, to continue the station's assembly.
