The Russian Orbital Station (ROS) will not just be a new space station, but a project focused on long-term operation. The uniqueness of ROS lies in its fundamentally new modular architecture, which allows replacing outdated or failed elements, unlike the International Space Station (ISS). This was announced by Ilya Zheleznov, a leading engineer at RSC Energia.
The key element of ROS is the universal node module.
The station will be able to be eternal because it has an open architecture that allows any outdated or damaged module to be replaced if necessary. In addition, the guaranteed service life of the universal node module, which will become the core of the station, is much longer than that of other modules due to its relative simplicity.
The first ROS module — the scientific and energy module (NEM) — has undergone significant improvements. It received an updated control system, six power gyrodynes for fuel economy, and a new passive docking unit. These improvements will ensure reliable and long-term operation of the station.
The first ROS module is planned to be launched into orbit in three years. For this, the Angara-A5M launch vehicle will be used.
