**Mir**Program: Mir.*Payload*: Mir s/n 127-01.*Mass*: 20,100 kg. Class: Manned.*Type*: Space station. Spacecraft: Mir .*Perigee*: 387 km.*Apogee*: 395 km.*Inclination*: 51.6 deg.*Period*: 92.4 min.*COSPAR*: 1986-017A.The core module of Russia's new space station was placed in an initial orbit of 172 x 301 km. It was established in its operational orbit on 6 March. It passed just 10 km from Salyut 7 on 8 March. First use of the geosynchronous Luch relay sattelite for communications with the station was on 29 March. Equipment launched with the core module included:

- Splav-2 crystal growth facility
- Zona zone melt facility
- Kashtan electrophoresis unit
- Bulgarian Rozhen photometer
- Spektr-256 and MKS-M spectrometers
- Pion-M multipurpose physics unit (41 kg)
- Biryuza semiconductor materials unit
- -Ruchei electrophoresis installation
- Yantar metal coating equipment
- Mariye magnetic spectrometer
- Korund furnace (136 kg)

Total costs of Mir from February 1986 through return of Soyuz TM-9 in April 1989 were given as 1.471 billion rubles. This sum ncluded Mir, Kvant, all Soyuz and Progress spacecraft, and 2 new modules. As of April 1989 50% of the scientific equipment was inoperable and the interior was cramped due to lack of extension modules. Electric power supply problems were first reported in April 1989 (batteries would not hold charge from panels). Mass 27,300 kg as of January 1990. Complex mass with Kvant-2 65,790 kg; with Kristall, Soyuz TM, and Progress M, 89,990 kg.
