"excellent work, guys, excellent," space station commander peggy whitson said after the wing was locked in place. "before we do the victory dance let's get scott safely back to structure and then we can all rejoice," discovery commander pamela melroy said as the shuttle's robotic arm started carrying parazynski back to the station. perched at the tip of the 90-foot robotic arm and boom extension, parazynski worked at the far left end of the linked shuttle-station complex, about 50 yards away from the pressurized compartments where the astronauts work and live. the ugly snag involved a guide wire, two hinge wires and two grommets. parazynski first clipped a hinge wire near the larger tear, using a special tool that looked like a hockey stick to make sure the panel didn't spring back and hit him. don't miss risky spacewalk tests astronauts' skill nasa wrestles ripped solar panel nasa: more info on spaceflight "it's a bit of a reach here," parazynski said as he stretched to cut part of the guide wire. "it's what those monkey arms are for," melroy said, referring to parazynski's 6-foot-2 height. as soon as parazynski cut the guide wire, the approximately 90-foot stretch of it recoiled all the way down into a reel where fellow spacewalker douglas wheelock was controlling and monitoring it. to everyone's relief, it retracted smoothly. "beautiful. nicely done," parazynski reported. parazynski's helmet camera sent close-up pictures of the damage to mission control and the space station, allowing the astronauts and experts on the ground to discuss the best way to tackle the damage on the gold-colored wing. the solar panel captures sunlight to generate electricity, and is alive with more than 100 volts of electricity, possibly as much as 160 volts. to reduce the risk of parazynski being shocked, all of the metal parts on his spacesuit were covered with insulating tape -- triple-taped, in fact -- as were all his tools. wheelock also kept a close eye on parazynski and his tools, guiding him to lean back when he got a bit too close to the swaying wing. without repairs, the wing posed a structural hazard for the international space station. the damage could have worsened and the wing could have become unstable, possibly forcing nasa to cut it loose and lose a vital power source for future laboratories. it was parazynski's fourth spacewalk this mission and the seventh of his 15-year astronaut career. e-mail to a friend copyright 2007 the associated press. all rights reserved.this material may not be published, broadcast, rewritten, or redistributed. all about international space station • space shuttles from the blogs: controversy, commentary, and debate sit tight, we're getting to the good stuff powered by sphere top newspolice: killed teen claimed he had a gunromney spends record amount on tv ads most viewed most emailed top searches 1 test results awaited in west death 2 'hannah' fan club sued over tix 3 o'connor's spouse finds new love 4 student: i was told what to ask 5 no arson charges for 10-year-old 6 ny teen: 'kill me. let's do this' 7 wars could cost $1.6 trillion 8 body of cop's third wife exhumed 9 how to be a heavenly houseguest 10 return of 'project runway'  view all » 1 how to keep your baby safe: 4 biggest... 2 student describes how she became a... 3 study: adhd kids' brain areas develop... 4 more than 1 million reported... 5 stomach virus races through cruise... 6 post-op 8-limbed girl 'doing well' 7 war costs could total $1.6 trillion... 8 'anonymous friend' gives $100 million... 9 enjoy a refreshing ham soda 10 police: teen hiding object shouts...  view all » 1 jena 6 2 michael vick 3 oj simpson 4 steve fossett 5 britney spears 6 madeleine mccann 7 youssif 8 blackwater 9 myanmar 10 halo 3  view all » most viewed most emailed top searches 1 gator eats robbery suspect 2 crack sentences 3 fatal child abuse 4 simpson hearing day 3 5 trouble on the set   1 fireworks mark frontier's end 2 gator eats robbery suspect 3 alleged victim sues u.s. 4 spain's new solar power tower 5 blast disrupts basketball game   1 video 2 ufo 3 john cena 4 moos 5 iraq 6 jeanne moos 7 korea 8 ron paul 9 larry king 10 pakistan   1 lakshmi tatma 2 cnn heroes 3 kanye west 4 gas prices 5 2007-2008 cold and flu season   today's featured product: samsung ln-t4671f • check prices • read review  8.0 out of 10 recent product reviews: creative live cam optia af • check prices • read review  6.3 out of 10 microsoft lifecam vx-7000 • check prices • read review  5.0 out of 10 canon dc230 • check prices • read review  6.6 out of 10 cnet.com ratings » more products reviews-----------------camcorderscamerascellphonescomputershandheldshome videomusicperipheralswi-fi home  |  world  |  u.s.  |  politics  |  entertainment  |  health  |  tech  |  travel  |  living  |  business  |  sports  |  time.com podcasts  |  blogs  |  cnn mobile  |  preferences |  email alerts  |  cnn radio  |  cnn shop  |  site map cnn en espaňol  |  arabic  |  japanese  |  korean  |  turkish international edition  |  cnn tv  |  cnn international  |  headline news  |  transcripts © 2007 cable news network. turner broadcasting system, inc. all rights reserved. terms of service  |  privacy guidelines  |  advertise with us  |  about us  |  contact us  |  help
