List of International Space Station expeditions. This is a chronological list of expeditions to the International Space Station (ISS). All permanent ISS crews are named Expedition n, where n is sequentially increased with each expedition. Resupply mission crews and space tourists are excluded (see List of human spaceflights to the ISS for details). ISS commanders are listed in italics.
