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 this 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. Shuttle officials initially thought the earlier piece may have been a narrow strip of thermal blanket that was yanked off the shuttle during launch, but images from the inspection showed no apparent damage, said flight director Mike Sarafin.

Boeing is a prime contractor for the shuttle program.
