Astronaut Sets U.S. Spacewalking Record

CAPE CANAVERAL, Fla. -- Astronaut Michael Lopez-Alegria broke the U.S. record for most time walking in space Thursday as he and another astronaut did maintenance work outside the international space station during their third spacewalk in nine days.
Lopez-Alegria surpassed the previous U.S. record of 58 hours and 32 minutes midway through his chores with fellow American Sunita Williams. He has a ways to go to claim the all-time record, though _ Russian Anatoly Solovyov has logged more than 82 hours.
The 6 1/2-hour spacewalk ended at 3:06 p.m. EST.
"They were all three extremely difficult (spacewalks), and you guys made them look not necessarily easy, but the way they should look," Mission Control said. "You did an excellent job."
Lopez-Alegria and Williams finished a primary mission of the their spacewalk: tossing quilt-sized thermal sheets from the international space station.
The two large thermal covers were folded up with smaller shrouds that had been covering an electronics box and were used to prevent parts of the space station from getting too hot or cold. Engineers believe they will burn up upon entering Earth's atmosphere in about three weeks.
"I don't think I could do it any better than that," Lopez-Alegria said to Williams as the first package floated away.
Lopez-Alegria joked that they had an easier time folding up the shrouds than their spacewalking colleagues who helped fold up a stubborn solar array during space shuttle Discovery's mission to the space station last December.
"Solar arrays wish they could retract this well!" he said.
In the past, engineers wanted to make sure that jettisoning items wouldn't strike the station, but they have grown more comfortable with the idea.
"We've gotten more proficient in jettison analysis and understanding the safety of jettisoning," lead spacewalk officer Glenda Laws said recently. "We expect the shrouds ... to look like a large bundle of laundry."
The astronauts also finished hooking up cables to a new system that will allow power from the station to be shared with a docked shuttle so it can stay longer; added a platform that will hold a storage container; and took photos of a docking port.
