The International Space Station is the result of years of collaboration by five individual space agencies (NASA, ESA, JAXA, ROSCOSMOS and CSA) and at least fifteen different partner countries. With materials launching from both the United States and Russia, construction on the station began in 1998 with the launch of the Zayra module and was officially completed in 2011.
ISS has been steadily inhabited for over ten years, with a new crew (Expedition) roughly every six months. The station has liveable space equivalent to that of a five-bedroom house, and is the length of an American football field.
The International Space Station is resupplied by Soyuz craft as well as automated transfer vehicles and, until its retirement, the Space Shuttle.
ISS crews work steadily to conduct research to advance scientific knowledge and develop new technologies.More on ISS
