The station was the first consistently inhabited long-term research station in space and was operated by a series of [[List of Mir Expeditions|long-duration]] crews. The ''Mir'' programme held the record for the longest uninterrupted human presence in space, at 3,644 days, until 23 October 2010 (when it was surpassed by the ISS),<ref name="Mirrecord">{{cite news|last=Jackman|first=Frank|title=ISS Passing Old Russian Mir In Crewed Time|url=http://www.aviationweek.com/aw/generic/story_channel.jsp?channel=space&id=news/asd/2010/10/28/11.xml|newspaper=Aviation Week|date=29 October 2010}}</ref> and it currently holds the record for the longest single human spaceflight, of [[Valeri Polyakov]], at 437 days 18 hours. ''Mir'' was occupied for a total of twelve and a half years of its fifteen-year lifespan, having the capacity to support a resident crew of three, and larger crews for short-term visits.

As a result, the vast majority of the station's crew were Soviet or Russian; however, through international collaborations, including the [[Intercosmos]], [[Euromir]] and [[Shuttle-Mir Program|Shuttle-''Mir'']] programmes, the station was made accessible to [[astronaut]]s from North America, several European nations and Japan. The cost of the ''Mir'' programme was estimated by former RKA General Director [[Yuri Koptev]] in 2001 as $4.2 billion over its lifetime (including development, assembly and orbital operation).<ref name="MirCost">{{cite news|title=Russians Find Pride, and Regret, in Mir's Splashdown |url=http://www.nytimes.com/2001/03/24/science/24MIR.html|publisher=New York Times|accessdate=9 March 2011|author=Patrick E.

==Originsမူလအစ==
''Mir'' was authorised in a decree made on 17 February 1976 to design an improved model of the [[Salyut program|Salyut]] DOS-17K space stations. Four Salyut space stations had already been launched since 1971, with three more being launched during ''Mir'''s development. It was planned that the station's core module ([[Mir Core Module|DOS-7]] and the backup [[Zvezda (ISS module)|DOS-8]]) would be equipped with a total of four docking ports; two at either end of the station as with the Salyut stations, and an additional two ports on either side of a docking sphere at the front of the station to enable further modules to expand the station's capabilities. By August 1978, this had evolved to the final configuration of one aft port and five ports in a spherical compartment at the forward end of the station.<ref name="Encyclopedia Astronautica"/>

It was clear that the planned processing flow could not be followed and still meet the 1986 launch date. It was decided on [[Cosmonautics Day|Cosmonaut's Day]] (12 April) 1985 to ship the flight model of the [[Mir Core Module|base block]] to the [[Baikonur cosmodrome]] and conduct the systems testing and integration there. The module arrived at the launch site on 6 May, with 1100 of 2500 cables requiring rework based on the results of tests to the ground test model at [[Khrunichev]]. In October, the base block was rolled outside its [[cleanroom]] to carry out communications tests. The first launch attempt on 16 February 1986 was scrubbed when the spacecraft communications failed, but the second launch attempt, on 19 February 1986 at 21:28:23 UTC, was successful, meeting the political deadline.<ref name="Encyclopedia Astronautica"/>

Firstly, the module would be launched independently on its own Proton-K and chase the station automatically. It would then dock to the forward docking port on the core module's docking node, then extend its [[Lyappa arm]] to mate with a fixture on the mode's exterior. The arm would then lift the module away from the forward docking port and rotate it on to the radial port that the module was to mate with, before lowering it down to dock. The node was equipped with only two ''Konus'' drogues, however, which were required for dockings. This meant that, prior to the arrival of each new module, the node would have to be depressurised to allow spacewalking cosmonauts to manually relocate the drogue to the next port to be occupied.<ref name="MirBIS"/><ref name="SSSM"/>

Once hard docking had been achieved, the tug undocked and deorbited itself. The docking module, meanwhile, was launched aboard {{OV|104}} during [[STS-74]] and mated to the orbiter's [[Orbiter Docking System]]. ''Atlantis'' then docked, via the module, to ''Kristall'', then left the module behind when it undocked later in the mission.<ref name="SSSM"/><ref name="STS-74"/> Various other external components, including three truss structures, several experiments and other unpressurised elements were also mounted to the exterior of the station by cosmonauts conducting a total of eighty spacewalks over the course of the station's history.<ref name="SSSM"/>
 
The station's assembly marked the beginning of the third generation of space station design, being the first to consist of more than one primary spacecraft (thus opening a new era in [[space architecture]]). First generation stations such as [[Salyut 1]] and [[Skylab]] had monolithic designs, consisting of one module with no resupply capability, whilst the second generation stations [[Salyut 6]] and [[Salyut 7]] comprised a monolithic station with two ports to allow consumables to be replenished by cargo spacecraft such as [[Progress (spacecraft)|Progress]]. The capability of ''Mir'' to be expanded with add-on modules meant that each could be designed with a specific purpose in mind (for instance, the core module functioned largely as living quarters), thus eliminating the need to install all the station's equipment in one module.<ref name="SSSM"/>
