was a space station
project begun in February 1976. Some of the modules built for Mir
-2 have been incorporated into the International Space Station
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 DOS-7 base block
used in the Mir
station. The DOS-8 base block was eventually used as the Zvezda
module of the ISS. Its design lineage extends back to the original Salyut
The Mir-2 project evolution was:
1981 to 1987: KB Salyut Mir-2
The prototype of the central module was as Polyus
-2 would be capable of docking at least four modules in ordinary operation.
14 December 1987: NPO Energia Mir-2
Designated as OSETS (Orbital Assembly and Operations Centre). The station would be built in a 65 degree orbit and consist of 90 tonne modules.
- Launch 1 - DOS 8,providing housing for the assembly crew.
- Launch 2 - 90 Tonne module.
- Launch 3 - Truss and solar arrays.
- Launches 4 to 6 - additional 90 tonne modules.
This would involve launch of the DOS-8, after which the Buran shuttle
would grapple the module, rendezvous with Mir
, and attach it to the old DOS-7 base block. This plan was after altered so that
DOS-8 would maneuver and dock itself to Mir
. It would remain attached for two years.
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 tonnes modules were planned:
- Docking Module - with the APDS universal androgynous docking system, and a side hatch for space walks
- Resource Module - Equipped with gyrodynes for orienting the station and a passive docking port for docking of Soyuz or Progress ferry spacecraft
- Technology Module - with materials experiments
- Biotechnology Module
November 1993: Mir-2 incorporated into the International Space Station
Russian elements of the International Space Station
- Zarya FGB, the first element launched. This was a US-funded TKS-derived propulsion module built by KB Salyut.
- Zvezda Service Module - this is the DOS-8 station, which was launched as the third major ISS module in July 2000.
- SO-1 (Pirs docking compartment) - one of the docking modules originally designed for Buran/Mir-2 was added to the station in September 2001.
