Vladimir Solovyov listed the key features of ROS

From 2027, Roscosmos plans to begin deploying the Russian Orbital Station (ROS), to which manned missions and scientific experiments will be transferred after Russia withdraws from the International Space Station project.

Vladimir Solovyov, General Designer for Manned Space Systems and Complexes at RSC Energia, revealed the characteristics by which ROS is superior to the ISS:

  • energy for target equipment is increased to 54 kW, as opposed to 30 kW on the ISS (of which only 3 kW on the Russian segment);
  • the data transmission speed to Earth has been increased to 300 Mbit/s, as opposed to 100 Mbit/s on the ISS;
  • The fuel supply has been increased to 9100 kg, in contrast to 6700 kg on the Russian segment of the ISS.

Selecting a polar orbit with an inclination of 96.8 degrees relative to the equator provides the following advantages:

  • a complete overview of the entire territory of Russia and the surface of the Earth with constant illumination;
  • the possibility of launching station modules and spacecraft from Russian territory (Russian cargo and manned missions to the ISS are launched from Baikonur in Kazakhstan);
  • landing of descent vehicles on Russian territory (they are now landing in Kazakhstan);
  • the ability to launch small satellites from the ROS board;
  • the ability to test equipment and radiation protection in conditions close to deep space;
  • the ability to monitor ice conditions on the Northern Sea Route.

The preliminary design of the ROS is already ready, the federal project has been prepared and is awaiting approval by the government. The budget for the creation of the station and new ships is estimated at 609 billion rubles. Vladimir Solovyov stated that RSC Energia will be ready to begin full-scale work on the creation of the ROS from 2024. It is planned that by 2030 the ROS will be deployed as part of four basic modules, and two target modules can be added two years later.
