Russian Orbital Service Station

[4] In April 2021, Roscosmos officials announced plans to possibly exit from the International Space Station programme after 2024, stating concerns about the condition of its aging modules.

[6][7][8] In December 2024, Roscosmos head Yury Borisov stated crewed flights to the ROS would be launched starting in 2028, simultaneously with the completion of the ISS programme as coordinated with NASA.

Initially intended to be launched to the International Space Station in 2024, NEM-1 will instead undergo 1.5–2 years of redesign to prepare the module for its new role as part of ROS.

During their stays, cosmonauts will install new components, check scientific equipment, conduct experiments and perform maintenance and repair tasks.

Roscosmos cites not only financial, but also safety reasons for this, "as it reduces the risk of cosmonauts receiving dangerous radiation doses".
