Russian Orbital Service Station

The Russian Orbital Service Station (Russian: Российская орбитальная служебная станция, Rossiyskaya orbital'naya sluzhebnaya stantsiya) (ROSS, Russian: РОСС)[3] is a proposed Russian orbital space station scheduled to begin construction in 2027. Initially an evolution of the Orbital Piloted Assembly and Experiment Complex (OPSEK) concept, ROSS developed into plans for a new standalone Russian space station built from scratch without modules from the Russian Orbital Segment of the ISS.[4]

Overview

edit

In April 2021, Roscosmos officials announced plans to possibly exit from the International Space Station programme after 2024, stating concerns about the condition of its aging modules. On 26 July 2022, Roscosmos announced that the decision had been made to withdraw from the ISS programme after 2024.[5] A new space station, named Russian Orbital Space Station, operated entirely by Roscosmos, would be launched starting in the mid-2020s.[6][7][8]

ROSS will operate at a 400-kilometer-altitude, near-polar and Sun-synchronous orbit, which will allow it to monitor the entire surface of the Earth, especially the Arctic region.[9] This orbit will enable the station to serve two important functions: high-frequency observations of Russia from space, and easier access to the station compared to the ISS, which will allow for more medical and physiological experiments to be conducted than what is currently feasible on the Russian Orbital Segment of the ISS.[10]

Planned modules

edit

NEM-1, also known as Science Power Module 1 (SPM-1), will be the core module of ROSS. Initially intended to be launched to the International Space Station in 2024, NEM-1 will instead undergo 1.5–2 years of redesign to prepare the module for its new role as part of ROSS. As of January 2023, NEM-1 is scheduled to launch in 2027[1] on an Angara A5 launch vehicle from Vostochny Cosmodrome, and a new Core module (similar to NEM-1) is scheduled to launch no earlier than 2028.[3]

ROSS is envisioned to include up to seven modules, with 2035 being the targeted completion date. The first stage of construction will consist of four modules: the base NEM-1 module, an upgraded NEM, a node module, and a gateway module. The second stage will include logistics and production modules, as well as a platform module for servicing spacecraft.[11] A commercial module for up to four space tourists is also under consideration.[7]

Planned extravehicular components

edit

There are plans for "multiple robotic systems on the exterior of the outpost to help with assembly and maintenance work".[12] The station is also planned to control "a family of small spacecraft" (satellites) to be launched directly from the station and "circl[ing] the globe in its vicinity", which would be a space first.[13]

Planned mode of operation

edit

In contrast to the continuously crewed ISS, ROSS will be visited by cosmonaut crews periodically, operating in automatic mode most of the time. During their stays, cosmonauts will install new components, check scientific equipment, conduct experiments and perform maintenance and repair tasks. Roscosmos cites not only financial, but also safety reasons for this, "as it reduces the risk of cosmonauts receiving dangerous radiation doses".[14]
