The full crews on both vehicles then reviewed the procedures to be followed throughout Hadfield and Parazynski's space walk. A second space walk is scheduled for Tuesday, and will focus on establishing power connections and checking out the new robotic arm. Expedition Two Commander Yury Usachev and Flight Engineer Susan Helms verified the performance of the station's carbon dioxide removal system, called Vozdukh, which had been operating in a slightly degraded condition. The system started working normally overnight on its own, and their checkout confirmed that it is operating within normal parameters. Usachev, Helms and Voss also exercised and continued preparations for the next week of joint operations with the Shuttle crew.
All systems are in good shape aboard both vehicles.
