Roscosmos intends to construct this new space station using modules from its segment that is currently connected to the International Space Station (ISS), which is only commissioned for operation until 2024.
The ISS is made up of two segments, the United States Orbital Segment (USOS) and the Russian Orbital Segment (ROS). The station is shared by about 15 countries, and five space agencies fund it – NASA, the Japan Aerospace Exploration Agency (JAXA), the European Space Agency (ESA), the Canadian Space Agency (CSA) and Roscosmos.
Roscosmos has been the only space agency able to send crew and cargo up to the ISS on its Soyuz rockets since 2011, when NASA retired its space shuttles.
The space agency aims to use the station as its cosmonauts’ base – and later, to actually send both orbiting missions around the moon and manned missions to the surface of the moon by 2030.
Roscosmos’ plans were discussed at a Scientific and Technical Council meeting under the chairmanship of Russian Space Agency’s Yuri Koptev, and they are hoping to develop a more detailed document of their plans at an upcoming meeting in March.
