International Space Station

The International Space Station is a modular space station in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA, Roscosmos, JAXA, ESA, and CSA. The ownership and use of the space station is established by intergovernmental treaties and agreements.

SpaceX is contracted to deliver cargo and crew to the ISS under NASA’s Commercial Resupply Services program, and began regular cargo flights in October 2012 and crew flights in May 2020.
