Atlantis Commander Steve Lindsey, Pilot Charlie Hobaugh and Mission Specialists Janet Kavandi, Jim Reilly and Mike Gernhardt will spend their first full day in space checking equipment in preparation for the major events to come on their 11-day mission: Friday's docking with the station and Saturday's first of three space walks.
With Gernhardt and Reilly assisting during a seven-hour space walk, scheduled to begin around 9 p.m. Saturday, Flight Engineer Susan Helms will use the station's new robotic arm -- Canadarm2 -- to remove the Quest airlock from the shuttle's payload bay and attach it to the right side of the station's Unity connecting module. The new airlock will enable station crews to perform space walks in U.S. space suits without the shuttle being present. This ability will enhance the station's capabilities for maintenance and construction and complete a major milestone in the station's orbital construction.
The International Space Station crew - Commander Yury Usachev and Flight Engineers Helms and Jim Voss - awoke at 2 p.m. The station crew will spend its day preparing for the Friday docking of Atlantis and the Saturday installation of the Quest airlock. The Expedition Two crew has been in space since March 8 and in charge of the space station since it took over from the Expedition One crew March 18.
