The International Space Station (ISS) is a multinational cooperative project involving the United States, Russia, Canada, Europe, and Japan. The construction of the ISS began in 1998, and it has been continuously inhabited since November 2000.
Roscosmos, Russia's space agency, has played a key role in starting the station. Examples of their contributions are: the Zarya module, the first module launched by the ISS that provided electrical power, storage, and guidance to the ISS during the initial stages of construction; the Zvezda service module, which serves as a key control center, living quarters, and life support system on board; and Russian research and laboratory modules.
In July 2022, Roscomos' head, Yury Borisov, announced intent to withdraw from the ISS after 2024 to build their own Russian station. No formalized request has been sent to NASA.
