Astronauts Get Time Off As Flight Winds Down

CAPE CANAVERAL, Fla. (AP) -- NASA gave shuttle Discovery's astronauts some well-deserved time off Thursday as their flight wound down and the international space station was left farther and farther behind.

Back on Earth, meanwhile, engineers scoured the multitude of wing and nose images beamed down by the seven shuttle crew members Wednesday following their departure from the space station.

The analysis - to uncover any signs of damage - began as soon as the first images hit the ground and continued all night. NASA expects to complete the work by early Thursday evening and, hopefully, conclude that Discovery can re-enter safely on Saturday.

The hours long survey with the 100-foot inspection pole typically is done the day after liftoff, to give engineers plenty of time to scour the images for any hint of launch damage to the wings and nose cap, particularly vulnerable during re-entry. Another briefer inspection usually is done after undocking, to check for any impacts from micrometeorites.

This time, everything was rolled into one.

"To my untrained eye, I personally didn't see anything unusual," flight director Matt Abbott said after the ring wing was scanned.

Discovery was so packed for its May 31 launch - Japan's Kibo lab practically filled the payload bay - that there wasn't room for the inspection boom. The previous shuttle crew left its inspection boom at the space station in March, and Discovery's astronauts retrieved it as soon as they got there.

A cursory inspection relying solely on the cameras on Discovery's robot arm, conducted June 1, revealed no problems. Photographs taken from the space station of the approaching shuttle also found nothing amiss.

NASA and Japanese space officials were delighted with the way Discovery's mission went.

Besides installing the billion-dollar Kibo lab - the biggest and fanciest lab up there - the astronauts delivered a new pump that fixed the space station's broken toilet, replaced an empty nitrogen gas tank and performed some detective work on a mysteriously clogged, solar wing rotating joint that has hampered energy production for months. NASA expects to replace all the bearings in the joint when the next shuttle visits in November.

The space station got a new resident as well.

"We go into every one of these missions, we plan for the worst and we hope for the best. I don't know if it was statistics or what, but on this particular mission, we got the best," said Kenny Todd, a space station manager.

The addition of Kibo represents "a crowning achievement," not only for Japan but all the space station partners, Todd said. "It's going to go a long way toward helping us implement the science program that's been laid out for us."
