Astronaut sets U.S. spacewalking record
CAPE CANAVERAL, Fla. — Astronaut Michael Lopez-Alegria broke the U.S. record of 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.
"Congratulations," Mission Control told the astronauts once they were inside. "They were all three extremely
difficult (spacewalks) and you guys made them look not necessarily easy, but the way they should look. 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.
"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. During the two earlier spacewalks, the astronauts had
changed the space station's cooling system from a temporary to a permanent system.
The spacewalk marked the first time three spacewalks have been conducted in such a short period without a
space shuttle docked to it. The first two spacewalks had similar tasks, and flight controllers thought they
could save preparation time by squeezing them together.
Lopez-Alegria planned to conduct a fourth spacewalk Feb. 22 with Russian flight engineer Mikhail Tyurin.
That spacewalk will be Lopez-Alegria's 10th. The previous U.S. time record for spacewalks was held by
astronaut Jerry Ross, who has made nine spacewalks.
Lopez-Alegria's new U.S. record is 61 hours and 22 minutes. Williams, who broke a record for female
spacewalkers last Sunday, now has 29 hours and 17 minutes of walking in space.
During Thursday's spacewalk, chief astronaut Steve Lindsey chatted with the spacewalk ground team. A day
earlier, he had escorted astronaut Lisa Nowak back to Houston from Florida, where she was charged with
attempted murder and attempted kidnapping, accused of trying to harm a woman she viewed as a romantic
rival for the attentions of astronaut William Oefelein. NASA has put her on leave for 30 days and removed
her from mission activities.
