The Discovery astronauts undocked from the international space station today, looped around the lab complex for a final photo run and then departed, falling back behind the outpost. Pilot George Zamka, manually guiding Discovery from the crew module's aft flight deck, had no problems despite a computer glitch that prevented him from receiving normal trajectory data.

"We're all just cheering Zambo on," Melroy told flight controllers. "I don't think people appreciate how difficult it is to do a fly around with absolutely no trajectory information. ... It's pretty challenging to do this and he's doing a fabulous job."

"We agree whole heartedly," said mission control. "We would never know he doesn't have the data. It looks great."

Astronaut Dan Tani, who hitched a ride to the station aboard Discovery and remained behind on the lab, replacing out-going Expedition 16 flight engineer Clay Anderson, passed along his own praise as a camera on the station showed the shuttle gliding through space 600 feet below.

"Discovery, Alpha on the big loop. Zambo, great job, buddy, great job flying," Tani said. "Really cool to see you out there."

"And Bo-ichi, thanks very much," Zamka replied, using the crew's nickname for Tani. "We're going to miss you, but we know you're going to have a great time up there with Peggy (Whitson) and Yuri (Malenchenko). Have a great expedition and we'll see you on the ground."

"I'll do that. And the whole 'Bo crew, I miss you already," Tani said. "Fly safe, get home safe, I'll see you on the ground and thanks for not only the great ride up, but the great year and a half together. I owe you one. ... Take care and we'll see you on the ground."

"Yep, we'll see you o the ground," said Melroy.

Discovery undocked at 5:32 a.m. EDT as the two spacecraft sailed 218 miles above the south Pacific Ocean.

"Houston and Alpha, Discovery has physical separation," Melroy radioed as the shuttle slowly pulled away from the lab complex.

A few moments later, station commander Peggy Whitson rang the ship's bell in the Destiny laboratory module, saying "shuttle departing."

"Discovery copies," Melroy said. "Thanks, Peggy."

"Thank you guys for the (new) module and all your help," Whitson replied.
