With the Worldwide House Station (ISS) set to retire in 2030, a number of nations and business area firms have plans to deploy their very own successor stations. This consists of China, which plans to double the scale of its Tiangong area station within the coming years, and the Indian Space Research Organization‘s (ISRO) proposed Bharatiya Antariksh Station (BAS), with the primary module focused for launch by 2028. Then you’ve gotten non-public ventures like Blue Origin’s Orbital Reef, Airbus’ LOOP, the Axiom Station, Vast’s Haven-1, and Starlab Space’s station.
Russia’s area company (Roscosmos) additionally plans to create a successor area station, although its plans have advanced over the previous few years. In line with a recent statement from Oleg Orlov, Director of the Institute of Biomedical Issues on the Russian Academy of Sciences (RAS), the brand new Russian Orbital Station (ROS) will embrace the modules that make up the Russian Orbital Phase of ISS – Zarya, Zvezda, Poisk, Rassvet, Nauka, and Pricha. The announcement was made on December 18th at a press convention on the Russia At this time (RT) worldwide multimedia press middle in Moscow.
In line with Orlov, a particular fee has been engaged on this course of for a number of months. The choice displays Russia’s geopolitical place amid the continued struggle in Ukraine, characterised by worldwide sanctions, terminated agreements, and diminished sources.
Evolving Idea
This represents an alteration of Roscosmos’ authentic plan, which was an evolution of the Orbital Piloted Meeting and Experiment Complicated (OPSEK) idea proposed in 2009. This station was to incorporate the modules that made up the Russian Orbital Phase, however the plan was deserted in 2017 after a feasibility examine confirmed it was extra favorable to take care of participation within the ISS program. In 2021, Roscosmos introduced that its involvement with the ISS program would finish in 2024, citing considerations in regards to the situation of its modules (a few of that are shut to 3 many years outdated).

At this level, the OPSEK idea was renamed the Russian Orbital Service Station (ROSS), or *Rossiyskaya orbital’naya stantsiya* (ROS) in Russian – to not be confused with the Russian Orbital Phase (additionally ROS). This up to date plan would not embrace Russia’s ISS modules, with plans for an inaugural launch of the scientific and vitality module deliberate for 2027. By 2030, Roscosmos deliberate to launch three extra modules that will make up the station’s core, together with the Common Node (UNM), Gateway (SM), and Base Module (BM).
By 2035, as much as three extra modules had been to be added to the station, with the potential for one non-public habitat for area tourism. The proposed station would accommodate a crew of two or extra cosmonauts and would have the ability to fly autonomously for months, if wanted.
Recycled Modules, New Orbit
The newest idea for the ROS displays Roscosmos’ altering scenario in recent times, owing to sanctions and the termination of worldwide cooperation following Russia’s invasion of Ukraine in 2022. In line with Orlov’s announcement, Russia will separate its modules from the ISS as soon as this system is accomplished in 2030, forming the core of the ROS, with different modules to comply with. “The Scientific and Technical Council of Roscosmos supported this proposal and authorized the deployment of a Russian orbital station as a part of the Russian phase of the ISS as the principle attainable situation,” stated Orlov, who was quoted by the Russian state information company TASS.
Orlov additionally indicated that the ROS would have an orbital inclination of 51.6 levels, which Orlov acknowledged was chosen for geopolitical causes. This orbit will permit Russia to launch from its newer websites that had been constructed to cut back Russia’s reliance on the Baikonur Cosmodrome in Kazakhstan – the Plesetsk Cosmodrome in Russia’s north, and the Vostochny Cosmodrome in Russia’s Far East. This has develop into all of the extra necessary because of the current harm inflicted on the Baikonur Cosmodrome, which has briefly halted all Roscosmos flights to the ISS.
This announcement displays what Denis Manturov, First Deputy Prime Minister of the Russian Federation, stated on Dec. 5th throughout a press convention on the Rossiya Nationwide Heart. On the time, Manturov acknowledged that on the finish of November, the RAS had determined to change the plan for a station in polar orbit (96 levels). This may allow orbital observations over everything of Russia and place experiments across the north magnetic pole (the place Earth’s magnetic subject gives nearly no safety in opposition to cosmic rays) to review the influence on residing organisms.
This new orbit will nonetheless permit Russia to launch cargo and crewed missions from its home launch websites. Manturov additionally acknowledged that India was contemplating the identical orbit for its Bharatiya Antriksh Station, and the choice would permit for worldwide cooperation between the 2 stations.

Unrealistic?
Nonetheless, there are some in Russia who’ve critical doubts that the ROS will stay serviceable lengthy sufficient for any such cooperation to happen. Maria Sokolova, writing within the Russian newspaper New Izvestia, penned a extreme indictment of Roscosmos’ and the RAS’s plan to recycle its ISS modules. The principle difficulty, she wrote, is feedback made by the identical Orlov back in 2022, the place he acknowledged that the rising downside of micro organism and fungi that had gathered on the ISS over time represented a menace to the security of astronauts and cosmonauts stationed there.
The assertion was made in an interview with Russia’s state-owned RIA Novosti. When requested why the modules of the Russian phase couldn’t be used to create the ROS, he acknowledged unequivocally:
An evaluation of the outcomes of microbiological monitoring of the habitat of the ISS RS modules, carried out throughout the framework of the full-time medical management operations, signifies that the state of the ISS habitat is deteriorating. It’s an goal course of. Generalized outcomes present that in 65% of the analyzed samples of the newest expeditions, microorganisms had been present in portions exceeding regulatory necessities. Among the many representatives of bacterial flora remoted from the habitat of the ISS, species which are of medical significance and are able to inflicting allergic reactions and a few forms of tender tissue and higher respiratory tract ailments have been recognized.
These points haven’t modified up to now three years; if something, they’ve develop into worse. Orlov’s expressed considerations additionally mirrored statements made the earlier 12 months in regards to the modules’ getting old situation, which prompted the choice to not reuse them. In essence, Russia’s determination to reuse its modules would imply that it might be inheriting all the ISS’s present issues, that are organic, technical, and structural. That is very true of Zarya and Unity modules, that are each 27 years outdated, adopted by Zvezda (25 years outdated).
These modules are all experiencing ongoing points on account of excessive temperature fluctuations and radiation, resulting in materials fatigue and air leaks. This requires steady upkeep by the crew, taking time away from scientific analysis and different actions the station was created to meet. In spite of everything, the ISS was initially designed for 15 years of service, however its lifespan has been prolonged many instances, which is resulting in diminishing returns on its scientific advantages. Alas, the motivation is obvious: Russia is dealing with a monetary disaster because of the struggle in Ukraine, and Roscosmos just isn’t resistant to its results.
