At 1:45 p.m. CDT on Monday (May 23), the hatches were closed between the International Space Station (ISS) and Soyuz TMA-20. Expedition 27 crew members Dmitry Kondratyev with Roscosmos, NASA astronaut Cady Coleman and Paolo Nespoli with the European Space Agency are preparing to undock at 4:35 p.m.
After it undocks, the Soyuz will move to between 590 and 650 feet from the space station and hold in place while Nespoli takes still photographs and video of the space station. The station will rotate 130 degrees to provide Nespoli
with ideal views of the complex with shuttle Endeavour attached.
The deorbit burn targeted for 8:36 p.m. will lead to a landing at 9:26 p.m. in Kazakhstan.
