Today in history.
Launched on October 11, 2000, STS-92 was a monumental milestone in space exploration, marking the 100th mission of the Space Shuttle program. Flown by Space Shuttle Discovery with a seven-member crew commanded by Brian Duffy, the primary objective was to continue assembling the International Space Station (ISS). Over the course of the 13-day mission, Discovery carried critical infrastructure to orbit, including the Zenith Z1 Truss, four Control Moment Gyroscopes for attitude control, and the Pressurized Mating Adapter-3 (PMA-3), which provided an additional docking port for future shuttle missions.
During seven days of docked operations, astronaut pairs performed four consecutive spacewalks to integrate the new components into the growing space laboratory. The crew successfully installed the Z1 Truss atop the Unity node, establishing the structural foundation for the station's future solar arrays, and maneuvered PMA-3 into place using Discovery's robotic arm. The mission also featured testing of the SAFER jet backpack, ensuring emergency spacewalker rescue capabilities. After completing all assembly objectives and paving the way for the ISS's first permanent crew, Discovery landed safely at Edwards Air Force Base in California on October 24, 2000.
