Shuttle Astronauts Recount Dramatic 15-Day Space Mission

Space shuttle Discovery's 15-day mission already seemed a bit like a dream to commander Pamela Melroy just hours after the crew's safe landing.

She recalled Wednesday how she and her crewmates cheered on the way home while admiring their makeshift patches to a wing on the international space station.

"That's one thing that we'll always look at the station and remember," she said. "So it feels a little more real to us in that way."

The shuttle touched down on a crisp and bright fall afternoon after safely crossing the continent in the first coast-to-coast re-entry since the Columbia disaster almost five years ago.

The seven shuttle astronauts and three residents of the international space station teamed up during the mission to save the mangled solar wing.

It was one of the most difficult and dangerous repairs ever attempted in orbit, but the future of the space station was riding on it and Scott Parazynski pulled it off in a single spacewalk.

The repair allows the space agency to press ahead with the next shuttle flight to the space station in early December.

On its way home, Discovery crossed over Canada's British Columbia and made a diagonal descent over Montana, Wyoming, the Great Plains, the Deep South and, finally, down into Florida.

NASA opted for the more populous route to avoid a riskier landing in darkness, and to give the crew some extra rest after such a long and strenuous flight.

Double inspections of the spaceship's wings in orbit confirmed the thermal shielding would hold up to the 3,000-degree heat of atmospheric re-entry. A quick look at the shuttle on the landing strip showed little if any damage.

NASA Administrator Michael Griffin said the flight, from start to finish, demonstrated "NASA at its very best." He described the landing as "spot on" and also "just as pretty as it gets — if that matters."

Even before the mission began Oct. 23, the astronauts knew they were in for one of the most challenging and complicated space station construction missions ever.

They had no trouble installing a pressurized compartment named Harmony and moving a girder from one side of the space station to another. They even managed to peek into a clogged joint needed to turn the right-sided set of solar wings.

But the flight took a dramatic turn Oct. 30 when it came time to unfurl the solar wings on the relocated girder on the left side of the space station. The first wing popped out fine, but the second one became snagged in a clump of tangled wires and ripped in two places.

Flight controllers rushed to come up with a repair plan. On Saturday — just four days after the damage occurred — Parazynski floated outside with wire cutters, pliers and some homemade tools and fixed the torn wing.

No one had ever ventured so far from the safe confines of the space station before or worked right up against a solar wing coursing with more than 100 volts of electricity and swaying back and forth. Parazynski was propped on the end of a 90-foot extension beam that just barely reached the wing's damaged section.

Parazynski admitted Wednesday night that he had more butterflies than usual before venturing outside that day. The fine print in the procedures sent up from Mission Control read, "'You may expect some sparkling or sparking in the damaged array,' and I thought, wow, that's pretty exciting. That's more exciting than I bargained for."

The astronauts gathered samples of the steel grit that was discovered inside the joint and brought them back in a plastic bag.

It was one of the first items NASA grabbed following touchdown.

By analyzing the shavings, engineers hope to pinpoint the source of the problem and devise a way to replace the grinding parts and clean up the mess, possibly with magnets.

Discovery also brought back a former space station resident, Clayton Anderson. He left the planet in June and spent 152 days in orbit.

Wednesday was his 15th wedding anniversary, and he couldn't wait to be reunited with his wife, Susan.

Melroy, meanwhile, became only the second woman to land a space shuttle. Her flight coincided with the first female-led space station crew, and catapulted Melroy and station skipper Peggy Whitson into NASA history books.
