This is a chronological list of spaceflights to the International Space Station (ISS), including long-term ISS crew, short term visitors, and mixed human/cargo missions. Unmanned visiting spacecraft are excluded (see List of unmanned spaceflights to the ISS for details). ISS crew members are listed in bold. "Time docked" refers to the spacecraft and does not always correspond to the crew.
Note: U.S. space shuttle missions were capable of carrying more humans and cargo than the Russian Soyuz spacecraft, resulting in more U.S. short-term human visits until the space shuttle program was discontinued in 2011. Since 2011, Soyuz is the sole means of human transport to the ISS, delivering mostly long-term crew. Russian cargo deliveries have been exclusively carried out by the unmanned missions of Progress spacecraft, requiring fewer human spaceflights.
