The space station's crew was awakened shortly after 3 a.m. EDT to make final preparations for the shuttle's arrival. The Expedition Two crew of Russian Commander Yury Usachev and astronauts Jim Voss and Susan Helms has been aboard the station for more than a month since assuming duty from the Expedition One crew on March 18. The spacewalkers also will install a UHF antenna on the station's exterior. Their second spacewalk Tuesday, features routing power and checking out the stations arm, which is longer, more flexible and more powerful than the robotic arm used by the shuttle fleet. If necessary, a third spacewalk could take place Thursday.
All systems are in good shape aboard both vehicles.
