Mir was a Soviet-Russian space station, flying from 1986 to 2001. Mir built on the Soviet space program’s previous success with the Salyut series of single-module space stations and modified them to interlock into new expandable modular space stations. The station was serviced by the Soyuz spacecraft, carrying cosmonaut crew members and the automated Progress spacecraft, carrying cargo. Both spacecraft were developed to service the previous Salyut stations and continue to be the primary vehicles to service the International Space Station today.
