International Space Station (1993–present)

The International Space Station (ISS) combines NASA's Space Station Freedom project with the Soviet/Russian Mir-2 station, the European Columbus station, and the Japanese Kibō laboratory module.^[59] NASA originally planned in the 1980s to develop Freedomalone, but US budget constraints led to the merger of these projects into a single multi-national program in 1993, managed by NASA, theRussian Federal Space Agency (RKA), the Japan Aerospace Exploration Agency (JAXA), the European Space Agency (ESA), and theCanadian Space Agency (CSA).^[60][61] The station consists of pressurized modules, external trusses, solar arrays and other components, which have been launched by Russian Proton and Soyuz rockets, and the US Space Shuttles.^[59] It is currently being assembled in Low Earth Orbit. The on-orbit assembly began in 1998, the completion of the US Orbital Segment occurred in 2011 and the completion of theRussian Orbital Segment is expected by 2016.^{[62][63][needs update]} The ownership and use of the space station is established in intergovernmental treaties and agreements^[64] which divide the station into two areas and allow Russia to retain full ownership of the Russian Orbital Segment (with the exception of Zarya),^[65][66] with the US Orbital Segment allocated between the other international partners.^[64]

Long duration missions to the ISS are referred to as ISS Expeditions. Expedition crew members typically spend approximately six months on the ISS.^[67] The initial expedition crew size was three, temporarily decreased to two following the Columbia disaster. Since May 2009, expedition crew size has been six crew members.^[68] Crew size is expected to be increased to seven, the number the ISS was designed for, once the Commercial Crew Program becomes operational.^[69] The ISS has been continuously occupied for the past 15 years and 346 days, having exceeded the previous record held by Mir; and has been visited by astronauts and cosmonauts from 15 different nations.^[70][71]
