 CONT: The Russian space station simulates gravity when it is  rotated. The direction that this force applies to people and objects  within the station and the two attached shuttles is inconsistent  with the geometry of the station. in reality, when the station is  spinning in that manner, gravity can be simulated however the two  shuttles would experience the gravity a different way, one crew  would be able to walk on the floors of the station, where the other  shuttle (being on the opposite side) the other folks would end up  walking on the celing, appearing upside down to their friends from  the first shuttle.
