International Space Station (ISS)

The International Space Station (ISS) is a global undertaking of tremendous scientific and engineering magnitude. Beginning in 1998, 15 nations began collaborating to construct, operate, and utilize an orbiting space laboratory with capabilities far surpassing all previous space platforms. These nations include the United States, Russia, Europe, Japan, and Canada. European countries are represented through membership in the European Space Agency (ESA). Current ESA members cooperating on the ISS are Belgium, Denmark, France, Germany, Italy, The Netherlands, Norway, Spain, Sweden, Switzerland, and the United Kingdom.

The ISS provides scientists, engineers, and entrepreneurs a unique research facility in which to perform complex, long-duration experiments. In addition to its six dedicated laboratory modules, the ISS supports a crew of three astronauts and provides external truss and exposed facility sites to accommodate a broad range of attached payloads for technology, Earth system science, and space science experiments.
