Expedition 1
Expedition 1, the station’s first long-term crew, explored a range of topics including how space affects biology and physics, and also studied Earth from above
1 began its resident-crew increment from the mission start recorded as Oct. 31, 2000 through March 21, 2001. William McMichael Shepherd, Sergei Konstantinovich Krikalev, and Yuri Pavlovich Gidzenko maintained the orbital laboratory, supported visiting vehicles, and carried out research and station work. Expedition 1, the station’s first long-term crew, explored a range of topics including how space affects biology and physics, and also studied Earth from above. The increment's crew, configuration, operational timeline, sources, and linked flight hardware are preserved together so the expedition can be followed as both a human mission and a distinct phase of station history.
