The ISS is a joint project of the United States, Russia, Japan, Canada, and 11 of ESA’s member states to build and operate a research facility in LEO that can host crews of up to six people. Assembly of the ISS in space began in 1998.
The best-known in-space platform is the International Space Station (ISS), a project led by the United States in conjunction with Russia, Canada, Japan, and several member nations of ESA. The ISS operates in LEO and serves as a research facility and testing laboratory. The station has been crewed by astronauts and cosmonauts from 15 different nations and has been serviced by a variety of spacecraft.
In addition to satellites and spacecraft, a third major facet of in-space activity involves in-space platforms. In-space platforms are facilities or modules constructed or placed in space with the intention of creating a permanent or semi-permanent location and resource base for staging further space activities. The International Space Station is the only operational in-space platform.
The largest in-space platform ever constructed is the International Space Station (ISS). The development of the ISS, led by the United States, “draws upon the scientific and technological resources of 16 nations: the United States, Canada, Japan, Russia, 11 nations of the European Space Agency, and Brazil,” according to NASA.[
