Building the International Space Station
ISS weigh almost 400 tonnes and covers an area as big as a football pitch. It would have been impossible to build ISS on the ground and then launch it into space in one go; there is no rocket big enough or powerful enough. To get round this problem the Space Station was taken into space piece-by-piece and gradually built in orbit, approximately 400 km above the Earth's surface. This has required more than 40 assembly flights.
A partnership between 10 European countries (represented by ESA), the United States (NASA), Japan (JAXA), Canada (CSA) and Russia (Roscosmos), the ISS is the world's largest international cooperative programme in science and technology to date.
In the following list the ISS assembly flights are coded with a number and a letter: A stands for America, R for Russian, E for European and J for Japanese. UL is 'Utilisation Flight', LF means 'Logistics Flight' and ULF is an abbreviation from 'Utilization and Logistics Flight'.
