Space Shuttle Endeavour lifts off on the 97th shuttle flight, and the only one on the 2000 launch schedule not devoted to construction of the International Space Station. Instead, Endeavour carries out an 11-day radar topography mission, though the 200-foot radar mast deployed from the cargo bay changes Endeavour’s center of mass and necessitates an unusually high usage of the orbiter’s fuel to keep the vehicle and payload properly oriented. Endeavour’s 14th crew is Commander Kevin Kregel, Pilot Dominic Gorie, and mission specialists Janet Kavandi, Janice Voss, Mamoru Mohri and Gerhard Thiele.
