CAPE CANAVERAL, Fla. - Space shuttle Endeavour's astronauts unfurled a 100-foot, laser-tipped pole and surveyed their ship for any launch damage Saturday while drawing ever closer to their destination, the international space station.
At least two pieces of debris were spotted Friday night in launch photos, Mission Control reported, and engineers were poring over the images to determine whether anything hit Endeavour. Mission Control told the astronauts there were no obvious signs of damage.
The spacecraft and its crew of seven were on track to hook up Sunday afternoon with the space station, currently home to three astronauts. The shuttle was delivering tons of equipment for remodeling, including a new bathroom, kitchenette, two sleeping compartments and an unprecedented recycling system for turning urine into drinking water.
"It's the eve of showtime," space station commander Mike Fincke told flight controllers on the ground. "Everyone get some rest. We're going to have a great day tomorrow."
The day centered around the shuttle inspections, standard procedure ever since Columbia shattered during re-entry in 2003.
During the afternoon, Ferguson's crew used the extra-long inspection boom to scrutinize Endeavour's right wing. The nose was next up, followed by the left wing. The painstaking job lasted well into the evening.
The shuttle wings and nose are especially vulnerable, taking the most heat when a shuttle descends through the atmosphere at the end of a flight. Even a seemingly minor gash could spell doom. Columbia was brought down by a hole in its wing the size of a dinner plate; all seven astronauts were killed.
Two pieces of debris were seen trailing Endeavour during Friday's liftoff, one at about a half-minute and the other just over two minutes into the flight. The earlier piece was likely a narrow strip of thermal blanket that was yanked off the shuttle during launch, said LeRoy Cain, chairman of the mission management team.
The blanket — 12 inches to 18 inches long and 4 inches wide — is believed to have come off the tail of the shuttle, near the orbital-maneuvering engine pod on the left side.
It's an area that does not get too hot during re-entry, so flight controllers are not overly concerned, Cain said. All the same, Mission Control asked the astronauts to photograph the area.
"You guys gave us some good pictures," Mission Control told Endeavour after the shuttle astronauts sent back images.
Cain said he had no information on the later piece of debris spotted in launch photos.
Virtually every inch of Endeavour will be photographed with zoom lenses when it approaches the space station late Sunday afternoon. Fincke ran through his picture-taking checklist with Mission Control on Saturday to make sure he had everything down.
A problem with a radio communication system on Endeavour th at doubles as radar could force Ferguson to rely on a backup navigation system for Sunday's rendezvous.
Once Endeavour is docked, the astronauts will begin unloading and installing the approximately 14,000 pounds of home-improvement equipment. It's all crucial if NASA is to expand the size of the station crew from three to six by next summer.
The space station currently has one kitchen, one bathroom and three bedrooms. Endeavour's delivery will transform the orbiting outpost into a two-kitchen, two-bath, five-bedroom home.
“In a way, this is a working man’s flight,” said NASA Administrator Michael Griffin.
“This is something that’s the size of a small ship, and it needs a lot to keep it running. This is one of the flights where we deliver those things,” Griffin told The Associated Press.
The accouterments — as Griffin calls them — also are intended to make life “bearable” for the astronauts spending months there.
Endeavour’s five men and two women will help install all the new equipment, with help from the space station’s three residents.
The shuttle crew also will take on a lube job at the orbiting outpost, which was soaring 220 miles (350 kilometers) above the South Pacific when Endeavour thundered off.
A massive joint that rotates half of the space station’s solar wings toward the sun has been jammed for more than a year; it’s clogged with metal grit from grinding parts. The spacewalking astronauts will spend most of their time working on that joint and also add extra grease to keep a twin joint working.
NASA hopes to stretch the mission to 16 days if possible, which would put touchdown late in the Thanksgiving weekend.
The space agency has just 10 more shuttle flights, including this one, before the fleet is retired in 2010 to make way for a new rocketship capable of flying to the space station and, eventually, carrying astronauts to the moon. An additional shuttle flight or two could be in NASA’s future, however, to try to narrow the projected five-year gap between the last shuttle flight and the first manned launch of the new spaceship.
