Space Shuttle Discovery lifts off on the 106th shuttle flight, a mission to exchange crews aboard the International Space Station. The shuttle’s cargo bay carries a logistics module containing more equipment for the ISS laboratory module, as well as storage racks to be installed elsewhere in the station. Aboard Discovery for her 30th flight are Commander Scott Horowitz, Pilot Frederick Sturckow, missions specialists Daniel Barry and Patrick Forrester, and ISS Expedition 3 crewmembers Frank Culbertson, Mikhail Turin and Vladimir Dezhurov, who remain aboard the station. Returning to Earth via Discovery are ISS Expedition 2 crewmembers Yury Usachev, James Voss and Susan Helms.
