Mir-2
Encyclopedia
Mir-2 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
(ISS). 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
stations.
DOS-8 would maneuver and dock itself to Mir. It would remain attached for two years.
). This was equipped with MSB retractable solar panels, Sfora thruster packages and small scientific packages.
Four 3 to 4 ton modules were planned:

Space station
A space station is a spacecraft capable of supporting a crew which is designed to remain in space for an extended period of time, and to which other spacecraft can dock. A space station is distinguished from other spacecraft used for human spaceflight by its lack of major propulsion or landing...

Mir Core Module
Mir , DOS-7, was the first module of the Soviet/Russian Mir space station complex, in low Earth orbit from 1986 to 2001. Generally referred to as either the core module or base block, the module was launched on 20 February 1986 on a Proton-K rocket from LC-200/39 at the Baikonur Cosmodrome...

Mir
Mir was a space station operated in low Earth orbit from 1986 to 2001, at first by the Soviet Union and then by Russia. Assembled in orbit from 1986 to 1996, Mir was the first modular space station and had a greater mass than that of any previous spacecraft, holding the record for the...

1981 to 1987: KB Salyut Mir-2
The prototype of the central module was as Polyus. Mir-2 would be capable of docking at least four modules in ordinary operation.December 14, 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 ton modules.- Launch 1 - DOS 8,providing housing for the assembly crew.
- Launch 2 - 90 ton module.
- Launch 3 - Truss and solar arrays.
- Launches 4 to 6 - additional 90 ton modules.
1991: "Mir-1.5"
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 later altered so thatDOS-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 PlatformScience Power Platform
The Science Power Platform was a planned Russian element of the International Space Station that was intended to be delivered to the ISS by a Russian Proton rocket or Zenit rocket but was shifted to launch by Space Shuttle as part as a tradeoff agreement on other parts of the ISS...
). This was equipped with MSB retractable solar panels, Sfora thruster packages and small scientific packages.
Four 3 to 4 ton 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
