Roscosmos discusses ISS withdrawal strategy and new space station for mid-2020swritten by Katya Pavlushchenko April 30, 2021Recently, Russian authorities began talking about a potential withdrawal from the International Space Station (ISS) project in 2025. In place of ISS, the Russian space industry would gain ROSS – a new orbital station that’s name stands for Russian Orbital Service Station. According to Roscosmos representatives, the withdrawal from the ISS will be gradual, which means that for some time the ISS and ROSS will work in space in parallel. At the same time, Russia and China have plans to build a lunar space station together.
I am skeptical that ROSS will happen (due to lack of proper funding), but I hope they can make it a reality. It would be cool to have a 3rd space stations in orbit at the same time, and it being in polar orbit as well.

From what I know about Soyuz, it can't put more than six tons or so into polar orbit. That seriously limits their ability to send cargo and crew in a progress/soyuz. And surely even Russia realises its a bit optimistic to relay on chainging their logistics flights from the Soyuz 2 to Soyuz 5 or Angara in the next four years.

But yes, the actual benefit of a polar station is questionable indeed, so it might not be worth the upgrades to fully human-rate the Soyuz 2.1b.
First there was OPSEK, and now there is ROSS. Something tells me that there will be another brilliant idea before they deliver anything to orbit.
The whole "independent Russian space station" scenario feels very, very much like a play by Roscosmos to force NASA to pay for keeping the Russian segment of the International Space Station going. A drop-in replacement for the loss of Soyuz seat money, if you will.
...I don't understand what Russia is hoping to accomplish with ISS withdrawal, it seems like even their most optimistic scenarios would leave their capabilities diminished.
Even at this stage the plan is that the station won't be permanently manned, this seems like a downgrade from ISS or even MIR.I don't understand what Russia is hoping to accomplish with ISS withdrawal, it seems like even their most optimistic scenarios would leave their capabilities diminished.
To be fair, NASA plans to ditch ISS not long after 2025 and handover LEO to commercial space stations, so it's not crazy for Russia to start planning for a post-ISS future. It's safe to say the Russians don't want to buy seats on US commercial stations, and the Chinese gave them the cold shoulder, this doesn't leave them a lot of choices.
Barely has ROSS been officially announced, or we're already seeing two different configurations of the station in RKK Energiya slides circulating on the web. Considering the dozens of changes that the ISS Russian segment went through since its inception, this is probably just the beginning of another long evolutionary path.In version 1 (see attachment) we see the following elements:-base module-node module-airlock module-logistics module-production module-servicing platform-commercial moduleVersion 2 (see attachment) consists of the following elements:-scientific power module (NEM) (phase 1)-base module (phase 1)-node module (phase 1)-airlock module (phase 1)-logistics module (phase 2)-production module (phase 2)-servicing platform (phase 2)-special-purpose module (phase 2)Version 1 is seen in this article published about two weeks ago:https://severnymayak.ru/2021/04/21/v-rkk-energiya-pokazali-kak-mogut-vyglyadet-moduli-novoj-rossijskoj-kosmicheskoj-stancii/The slides seem to come from the RIA Novosti news agency, but they do have the RKK Energiya logo. Version 2 is seen in a recent presentation by Vladimir Solovyov at a meeting of the Academy of Sciences and in a recent TV report aired from RKK Energiya. I presume this is now considered the “prime” version. I’ve also attached slides of most of the individual modules:SCIENTIFIC POWER MODULE (NEM) / BASE MODULE-to be launched by Angara-A5 from Plesetsk or Vostochnyy- they look identical and have the same functions (the most important ones being power supply and provision of crew quarters). In version 2, NEM is described as the first element and needed “to ensure control of the station until the arrival of the base module”. Presumably, the second, nearly identical module is needed to increase crew capacity and power supply. AIRLOCK MODULE:-to be delivered by a Progress-M-UM tug launched by Soyuz-2.1b from either Plesetsk or Vostochnyy-provides EVA capabilityLOGISTICS MODULE:-two versions are proposed, one based on the NEM design (requiring launch by an Angara-A5 from Plesetsk or Vostochnyy) and the other a smaller vehicle with an inflatable cargo section (delivered by a Progress tug launched by Soyuz-2.1b from Plesetsk or Vostochnyy)-to be used for storage of equipment and supplies. The bigger version can house “payloads for free-flying satellites” and “large structures to be assembled on the outer surface of the station”. The smaller inflatable version could house equipment needed for physical exercises.PRODUCTION MODULE:-based on the NEM design and launched by Angara-A5 from Plesetsk or Vostochnyy-among its functions are assembly of satellites, production of various parts using a 3D printer, production of materials that cannot be obtained in gravity conditions, remote sensing (both an optical telescope and a radar are seen mounted on the outside of the module)SERVICING PLATFORM:-to be delivered by a Progress-M-UM tug launched by Angara-A5 from Plesetsk or Vostochnyy-to be used for servicing of satellites (replacement and repair of components, refueling satellites with UDMH, N2O4, xenon, helium and krypton, recharging satellites using the energy resources of the base module) , launch of small satellites, assembly of large structures such as antennas, telescopes and mirrors, station attitude control using control moment gyroscopesCOMMERCIAL MODULE:-based on the NEM design and to be launched by Angara-A5 from Vostochnyy-will provide comfortable living quarters for “spaceflight participants” (that is tourists) and will also house commercial experiments. The “commercial module” in version 1 may be the same module that is described as the “special-purpose module” in version 2.
There are several proposed configurations with optional modules and external platforms on the table. Anatoly Zak goes into details on his site. The two variants shown were shown in recent meeting to a military oversight commission.http://russianspaceweb.com/ros.html some links inside require a subscription at this time.
I understand this is a module being proposed for the new Russian space station ("modul-stapel" in Russian).See the ROSS thread:https://forum.nasaspaceflight.com/index.php?topic=53721.0
One module was docked to the ISS, now we are preparing the next. Today, the nodal module # Berth went to the Baikonur cosmodrome. Its launch into orbit as part of the Progress M-UM cargo vehicle-module is planned for November 2021.https://twitter.com/roscosmos/status/1421463419786600451
Progress M UM flies to the ISS, not to the planned ROSS station
AFAIK; The module shown in the tweet is the Prichal (Nodal) module that will be mounted to MLM; Nauka nadir.I've written a long post in the Russia pullout of ISS by 2025 [ISS] topic. I was wrong there about reusing russian ISS modules for ROSS. But Prichal allows keeping the newer Russian modules at the ISS, while ditching FGB (Zarya) and SM (Zvezda), though it's not likely.I actually like the idea of an optionally manned SSO station. Crew at the ISS is losing a lot of time maintaining the ECLSS systems, especially for their needs. So operating unmanned/ remote controlled with internal robotics allows a lot of science to be performed. I remember a DLR paper from a couple of years back; where they put all the functions into one module. (Base/NEM and external experiments module (with payload airlock). So the ROSS concepts are in my opinion already large for a optionally manned station. ROSS looks capable of sustaining crew for long duration.

Russia can launch the first module of its orbital station as early as 2026, "if you push yourself hard," said Dmitry Rogozin, head of Roscosmos.“Now, I think, if we push ourselves hard, then in 26 we could put the first module into orbit,” he said at a meeting with State Duma deputies from the Liberal Democratic Party .As the head of the state corporation clarified, he does not consider the work on the ISS to be effective in the current conditions, and the Russian orbital station will be several times more efficient.Earlier, Rogozin stated that the decision to extend the service of the station after 2024 had not yet been made, and without Russian participation, the station was doomed, as it had reached its deadline.The head of the state corporation also expressed the opinion that the ISS could simply "fall apart" before 2030.“So far we have government permission to work on the ISS until 2024. The United States has decided to work there until 2030. We believe that the station will fall apart by 2030. Its resource is 15 years. is he.Earlier, Rogozin said that Roskosmos is responsible not only for the orientation of the ISS and for its withdrawal from dangerous collisions, but also for the delivery of fuel. According to him, if the government's decision to extend the operation until 2030 is not accepted from the Russian side, then "he does not know how the Americans will cope with the station."https://ria.ru/20220310/kosmos-1777491159.html

Specialists have also calculated the cost of delivering 1 kg of cargo, the cost of deploying the station in its initial configuration and transferring space vehicles from the station’s orbit to the near-Moon orbit. This stage is due to be completed by June this year and its results will be examined by the Roscosmos Scientific and Technical Council.
Now Rocket and Space Corporation Energia is working on a draft design of a new Russian Orbital Service Station (ROSS). In particular, the station's orbit will be chosen during the design process - the ROSS will either be left in the same orbit in which the ISS flies, or placed in a high-latitude orbit with an inclination of 97 degrees in order to see the Arctic and observe the Northern Sea Route. The preliminary design of the ROSS should be completed in the third quarter of 2023, after which the development of design documentation will begin.https://ria.ru/20220601/mks-1792347120.html

I thought these ideas died in the 60ties.It's supposed to be a kind of hub for different kinds of satellites and platforms. I think the crews would be doing repairs, not actually doing the observing themselves.Russia needs to maintain a human spaceflight programme that is independent to sustain its self image, so I assume a station is the cheapest option available alongside the participation in the ILRS (in fact there may turn out to be a convergence between the two if the Ryvok concept comes to fruition). Given this underlying requirement, they must have sought to make as much use of it for other purposes, as well as to bring the MoD on board (and vice-premier Yuri Borisov, responsible for defence and space industry, is one of the driving forces behind it).
I was deeply skeptical about this station, but deciding to put it in an SSO orbit makes me even more deeply skeptical, for several reasons:- The performance loss to SSO makes it a far trickier station to reach than ISS. Less cargo on Progress, Soyuz may not reach it all (and if it does, with razor thin margins). They might have to wait for their next-gen capsule on Angara 5, but that will be much more expensive and add a long pole in the schedule.- Crew launch and landing safety. Presumably they will launch northwards from Vostochny, but the abort zones will be very remote or in the Arctic Ocean. And landing opportunities over Russia or Kazakhstan will presumably be fewer per day. (Depending on their preferred landing area)- Crew radiation exposure at SSO, supposedly greater than at ISS.No, despite as cool as a space station in polar orbit sounds, I predict this SSO decision will be reversed or the project cancelled.
The post-Russian extension of the life of the ISS is complicated by its design: it is the engines of the domestic Zvezda module that are responsible for correcting the station's orbit and correct position in space. It is simply impossible to separate this segment - the ISS will cease to exist. According to Solovyov, recently the Americans are inclined to flood the structure.

Are the conical sections with the docking interface identical between the Oryol spacecraft and the ROSS modules; NEM; Base, Production and Purpose? That could be smart use of the same structure, with serial production advantages.I think an optionally manned polar station, that could host payloads and service polar satellites is a smart concept. But it would be nice if it could exist besides the ISS. And I would like Russia to act different than how they are acting especially this year, but also the past decade.
Roscosmos for the first time showed the layout of the Russian orbital station“According to preliminary studies, at the first stage, the station will include four modules - scientific and energy, nodal, base and gateway ... At the second stage, the Russian orbital station is planned to be supplemented with target and production modules, as well as a service platform,” the Roscosmos website reports. .
No work on the modernization of #Soyuz2.1b to launch crewed ships is currently on schedule, said the press service of #RSCProgress on the Army-2022 forum. Previously, Vladimir Soloviev said in his big interview that it will be necessary for crewed flights to ROSS space station.
Roscosmos announced the launch of modules of the Russian orbital station in 2027-2030MOSCOW, 13 February. /TASS/. The Science and Energy Module (NEM) of the Russian Orbital Station (ROS) will be launched in 2027, and four more modules will go into orbit in 2028-2030. This was announced in an interview with TASS by Deputy General Designer of the Energia Rocket and Space Corporation (part of Roskosmos), Chief Designer of ROS Vladimir Kozhevnikov."At the moment, we plan to launch the first, scientific and energy, module at the end of 2027, the nodal, gateway, basic and target modules - for the period 2028-2030," Kozhevnikov said.According to the chief designer, the timing of the plant's deployment will be determined based on the results of the preliminary design, which will be completed this year. "The work on the NEM, after a pause, has been deployed in full. The draft design of the ROS defines the requirements for its completion, which will be implemented starting from 2024. The launch of the NEM into the orbit of the ROS is planned using the Angara-5M rocket," he explained.At the same time, the station, Kozhevnikov stressed, will be practically "eternal". "The proposed project provides for the possibility of replacing worn-out modules. This will not only keep it operational, but also ensure that the technical and technological equipment of the station is up to date," the chief designer added.Kozhevnikov also recalled that the launch of crews to the new orbital station is planned with the help of a promising transport ship from the Vostochny cosmodrome. This will make it possible to implement the "new station - new ship - new spaceport" strategy.In April 2021, Yuri Borisov, who at that time was Deputy Prime Minister, stated that the state of the ISS leaves much to be desired, so Russia can focus on creating its own orbital station. At the moment, its preliminary design is underway. In October, Deputy Prime Minister - Head of the Ministry of Industry and Trade of the Russian Federation Denis Manturov told reporters that the preliminary cost of creating a promising Russian orbital station is already known.

🎥 At the Army-2023 International Military-Technical Forum, RSC Energia demonstrated new capabilities of the Russian Orbital Station
In October 2023, Yuri Borisov, head of Roscosmos, said that the cost of the station was estimated at 609bn rubles until 2032, of which 150bn is planned to be spent in the first three years. According to him, the project is open for international co-operation: for example, the countries of Africa and BRICS have been offered to participate in the creation of the station.As Vladimir Kozhevnikov, deputy general designer of the Rocket and Space Corporation (RSC) Energia (part of Roscosmos) and chief designer of ROS, told TASS in February, the launch date of the first, scientific and energy module is currently scheduled for the end of 2027, while the node, airlock, base and target modules are to be launched between 2028 and 2030. According to Vladimir Soloviev, general designer of manned space systems and complexes, general designer of RSC Energia, academician of the Russian Academy of Sciences, the station may operate in orbit for half a century.
