== Project history ==▼
The project underwent many changes, but was always based on the DOS-8 base block space station core module, built as a back-up to the [[Mir Core Module|DOS-7 base block]] used in the ''[[Mir]]'' station. The DOS-8 base block was eventually used as the ''[[Zvezda (ISS module)|Zvezda]]'' module of the ISS. Its design lineage extends back to the original [[Salyut]] stations.▼

===The evolution of the ''Mir''-2 project===
▲====1981 to 1987: KB Salyut Mir-2====
The prototype of the central module was as [[Polyus (spacecraft)|Polyus]]. ''Mir''-2 would be capable of docking at least four modules in ordinary operation.
===
Designated as OSETS (Orbital Assembly and Operations Centre). The station would be built in a 65 degree orbit and consist of 90
*Launch 1
*Launch 2
*Launch 3
*Launches 4 to 6
====1991: "Mir-1.5"====
This would involve launch of the DOS-8, after which the [[Buran (spacecraft)|Buran shuttle]] would grapple the module, rendezvous with ''Mir'', and attach it to the old DOS-7 base block. This plan was later altered so that
DOS-8 would maneuver and dock itself to ''Mir''. It would remain attached for two years.
====1992: "Mir-2"====
The station would consist of the DOS-8 core module and a cross beam called the NEP ([[Science Power Platform]]). This was equipped with MSB retractable solar panels, Sfora thruster packages and small scientific packages.
Four 3 to 4
*Docking Module - with the APDS universal androgynous docking system, and a side hatch for space walks

====November 1993: International Space Station built around Mir-2====
[[File:Russian Orbital Segment.png|thumb|right|270px|The [[Russian Orbital Segment]]]]
Russian elements of the [[International Space Station]] include:
*[[Zarya (ISS module)|Zarya]] FGB, the first element launched. This was a US-funded [[TKS spacecraft|TKS]]-derived propulsion module built by [[Khrunichev State Research and Production Space Center|KB Salyut]].
*[[Zvezda (ISS module)|Zvezda]] Service Module - this is the DOS-8 station, which was launched as the third major ISS module in July 2000.
*SO-1 ([[Pirs (ISS module)|Pirs]]) - one of the docking modules originally designed for Buran/''Mir''-2 was added to the station in September 2001.
*SO-2 [[
*[[Rassvet (ISS module)|Rassvet]] - the only module delivered by NASA shuttle, in a barter exchange for the launch 'owed' for Zarya. Rassvet is used for cargo storage, science, and as a docking port for visiting spacecraft.
