The Atlantis astronauts are gearing up to undock from the International Space Station today at 4:53 a.m. EST. Pilot Barry Wilmore will carry out a 360-degree photo-documentation fly-around before departing the area just after 6:30 a.m.

"It's a good day for the pilot the way we plan 'em out," he said in a NASA interview. "The pilot is actually the one who is on the controls as you undock from station. So we'll undock and I'll be doing the fly out, if you will, back out the V-bar (directly in front of the station) to about a 150, 200 feet thereabouts and then we'll affect some burns that will put us in a trajectory where we actually will fly all the way around the station and with our payload bay pointing at the station the whole way.

"We'll fly around about 600 to 650 feet (from the station). As we affect that maneuver coming all the way out, as we get back to where we started on that plus V-bar, we'll do a burn that will put us initially on a trajectory to leave station and start on our way home. So as I will do that burn going home, going home to my wife, Deanna, and our two girls, that'll be a neat time."

A post-undocking inspection of the shuttle's reinforced carbon carbon nose cap and wing leading edge panels is scheduled to begin around 9:18 a.m. to look for any signs of damage that might have occurred since a similar inspection the day after launch. A mission status briefing is on tap at 11:30 a.m., followed by a Mission Management Team briefing at 3:30 p.m. The crew will go to bed at 5:28 p.m.
