NASA says Discovery looks safe to fly home

— Space shuttle Discovery escaped damage from the potentially deadly chunk of foam that broke off from the fuel tank during liftoff, but may have been struck in the wing by a much smaller piece, NASA said Thursday.

Even if the small foam fragment did hit, engineers believe the impact caused no damage of concern, said deputy shuttle program manager Wayne Hale.

"This is the closest to a potential hit that we have out of all the data we've got," Hale said at an evening press conference. That's why it generated "a great deal of interest," he said.

Despite the latest development, officials said Discovery still looks safe to fly home Aug. 7, but stressed it will be another few days before the space agency can conclusively give the shuttle a clean bill of health.

The mostly welcome news came after Mission Control received stunningly detailed photographs of Discovery taken by the crew aboard the international space station. The shuttle executed an unprecedented backflip to bare its belly to the cameras before docking with the space station.

NASA wanted to make sure Discovery did not suffer the kind of mortal wound that brought down Columbia in 2003.

All that remains before NASA can clear Discovery and its seven astronauts for landing is an inspection today by a new laser-tipped boom that will provide 3-D views of scraped thermal tiles on the shuttle's belly. The 100-foot crane will be able to determine the depth of what looks to be surface-coating damage, said John Shannon, flight operations manager.

One of the areas of biggest interest is a chipped thermal tile near the set of doors for the nose landing gear.
