Overview
Endeavour's pre-dawn launch at 2:28 a.m. EDT on 11 March 2008 opened one of the most ambitious assembly flights in International Space Station history. The 25th shuttle mission to the station carried contributions from two partner agencies at once: the Experiment Logistics Module–Pressurized Section, the first element of Japan's Kibo laboratory complex, and Dextre, the Canadian Space Agency's two-armed Special Purpose Dexterous Manipulator. After docking on 13 March, the crew berthed the Japanese logistics module to the Harmony node and, across multiple spacewalks, assembled Dextre's arms and tool systems on a pallet in the payload bay. Five EVAs in total — the most of any shuttle visit to the ISS — also tested a heat-shield repair material and stowed the orbiter's inspection boom on the station for the next flight. Mission specialist Bob Behnken, later to pilot the first commercial crew flight, performed three of the spacewalks. Endeavour stayed docked for a record 11 days, 20 hours and 36 minutes, exchanging station crew members along the way: Garrett Reisman remained aboard while ESA's Léopold Eyharts came home. A rare night landing at Kennedy Space Center at 8:39 p.m. EDT on 26 March closed a flight of 15 days and 18 hours.

Legacy & Significance
STS-123 embodied the International Space Station at its most international: a single shuttle flight carrying Japan's first piece of crewed orbital real estate and Canada's robotic handyman, installed by a crew that included astronauts from three agencies. Dextre went on to take over external maintenance tasks that once demanded spacewalks, extending the safe working life of the station, while the Kibo logistics module was the vanguard of what became the ISS's largest laboratory complex. The mission also launched the spaceflight career of Bob Behnken, who twelve years later piloted SpaceX's Demo-2 — the flight that returned crewed launches to American soil after the shuttle's retirement.
