I'm wondering how the traditional walk-about the shuttle by it's crew is handled now when they have astronauts that have been on the ISS for long duration flights. Silly question, but would... let's say Sunita Williams be able to do the traditional walk-about Atlantis when they land? Something tells me that the answer is 'no'. It's been a long time since I've been able to catch a shuttle landing (RealPlayer originally), but now thanks to cable, I have NASA TV. lol

[Shepherd, Gidzenko and Krikalev will be seated in specially-designed recumbent seats on Discovery's middeck for entry and landing. Returning to Earth in this reclined position, allows the g-forces experienced during reentry and landing to be distributed more evenly through the astronaut's body, allowing them to adapt more gradually to the presence of gravity.

Returning astronauts, including Shepherd, Gidzenko and Krikalev may experience orthostatic intolerance, a feeling of light headedness or fainting when standing in an upright posture, as they return to Earth. Returning to Earth in these recumbent seats, rather than sitting in an upright position, reduces the effects of orthostatic intolerance. The light headedness occurs when gravity pulls fluids downward, away from the heart and head. Recovery is generally rapid and there are no requirements for the Expedition One crew to be removed from Discovery in a reclining position.

The crew will not be medically monitored during the re-entry, but will undergo routine post-flight evaluations by flight surgeons shortly after landing. Shepherd, Gidzenko and Krikalev then will join their STS-102 crew mates in the crew quarters building at the Kennedy Space Center for a brief reunion with their families prior to more extensive physical exams.]
