Russian Orbital Service Station, ROSS

In early 2020, Russian engineers completed a proposal for a modular Earth-orbiting outpost, which could succeed the International Space Station, ISS, and provide the nation's space program with a back-up destination in case Moscow's lunar ambitions wither due to lack of funding or political will. The complex was known as the Russian Orbital Service Station, ROSS, and was assigned the industrial designation 615GK.

OPSEK: Earliest concept of the Russian successor to the ISS

In April 2001, the Russians, still shaken by the painful demise of the Mir space station, were facing a row with NASA over its objection to flying wealthy tourists to the ISS in order to obtain extra cash during the most difficult years of the country's economic transition. In the midst of the brouhaha, the head of the Russian space agency, Yuri Koptev, made the first public statement about a small Russian space station as a successor to the ISS.

VShOS: Russian orbital station gets new impetus

On December 15, 2014, answering questions from journalists at the end of an annual press-conference, the head of Roskosmos, Oleg Ostapenko said that the agency had been considering options for the development of the High-Latitude Orbital Station, also known by its Russian abbreviation as VShOS.

ROS: Engineers begin looking at the station concept

RKK Energia, the nation's premier manned spacecraft contractor, reported that it had delivered the Technical Assignment for the future station to TsNIIMash, the main expert and certification center of the Russian space industry in October 2016. TsNIIMash was expected to review the specifications and submit them to the leadership at the Roskosmos State Corporation.

2020: Concept evolves (INSIDER CONTENT)

In early 2020, Russian engineers completed a proposal for a modular Earth-orbiting outpost, which could succeed the International Space Station, ISS, and provide the nation's space program with a back-up destination in case Moscow's lunar ambitions wither due to lack of funding or political will.

NEW, April 4: 2021: Building the station from scratch (INSIDER CONTENT)

In a major strategy U-turn, the Russian industry favored the construction of a brand-new space base in the Earth's orbit instead of separating its newest modules from the International Space Station, ISS, at the end of its life. The latest plan proposes building the future outpost in a drastically different orbit which overflies far more of the Russian territory and other high-latitude areas than the ISS.

Russia mulls new station design to compete in commercial race (INSIDER CONTENT)

In the 2020 study, Russian strategists provided a set of fresh justifications for the construction of a new Russian Earth-orbiting outpost, drafted its new possible architecture and technical capabilities as well as outlined different scenarios for its deployment in orbit. The plan also revisited various concepts of transport vehicles for the re-supply of the future station.

Rationale for the ROSS concept (INSIDER CONTENT)

Proponents of the future Russian outpost to succeed the International Space Station push forward some really exotic, if not bizarre, ideas to justify the concept along with more traditional uses.

NEW, April 14: ROSS assembly sequence (INSIDER CONTENT)

In the Spring of 2021, the Russian space industry drafted a new assembly schedule for the ROSS complex. The latest scenario aimed at building a brand-new outpost in parallel with the winding down ISS operations but in a different orbit.

FGB-2

Multi-purpose Laboratory Module, MLM

The construction of the Russian Orbital Station depended on the launch of the Multi-Purpose Laboratory module, MLM Nauka (science). As of 2020, its long-delayed launch to the International Space Station, ISS, was expected in 2021. The Nauka will serve as the "border-line" module, connecting future Russian station to the old Russian Segment of ISS.

Node

The so-called "Uzlovoi Module" or Node Module will play a role of the hub of the future Russian station, make the life span of the new outpost essentially unlimited, as long as new modules replace the old ones.

NEM

NEW, April 29: Converting Science and Power Module, NEM

Plans for building a future orbiting outpost from scratch instead of separating its newest modules from the retiring International Space Station, ISS, depends on converting the yet-to-be-launched Science and Power Module, NEM, into the core of the future station. However, this strategy posed a number of major technical and financial obstacles.

Gyroscopic Module (INSIDER CONTENT)

Eyeing a possible life for the Russian Segment after the deorbiting of the International Space Station, ISS, engineers at RKK Energia proposed a new module designed to give the post-ISS station the capability to stir itself in space without use of propellant.

ShM

Airlock Module, ShM

While planning for the expansion of the Russian segment of the International Space Station, ISS, in the second half of 2000s, engineers at RKK Energia conceived a new Airlock Module, ShM, which would replace a Docking Compartment, SO, currently used for spacewalks. The new design also evolved to support the orbital assembly of deep-space vehicles.

Inflatable

Half a century after Aleksei Leonov floated into open space through the inflatable airlock, the company that built his spacecraft, has jump-started work on multi-layered inflatable structures. In its annual report for 2012, RKK Energia said that the new project might pave the way for a new generation of space station modules, interplanetary spacecraft and planetary bases.
