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. Endeavour s cabin pressure was lowered to 10.2 pounds per square inch Friday afternoon in preparation for that spacewalk, while the atmosphere inside the station remains a normal 14.7 psi. 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 at 57.7 feet long, 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.
The next status report will be issued Saturday afternoon, or as events warrant.
