List ofMirspacewalks

A view ofMiron 12 June 1998 as seen from the departingSpace ShuttleDiscoveryduringSTS-91

Mir(Russian:Мир,IPA:[ˈmʲir];lit.PeaceorWorld) was aSovietand laterRussianspace station,operational inlow Earth orbitfrom 1986 to 2001. With a mass greater than that of any previous space station,Mirwas constructed from 1986 to 1996 with a modular design, the first to be assembled in this way. The station was the largest artificialsatelliteorbiting the Earth until itsdeorbiton 21 March 2001, a record now surpassed by theInternational Space Station(ISS).Mirserved as amicrogravityresearchlaboratoryin which crews conductedexperimentsinbiology,human biology,physics,astronomy,meteorologyand spacecraft systems in order to develop technologies required for the permanent occupation ofspace.

Following the success of theSalyut programme,Mirrepresented the next stage in the Soviet Union's space station programme. The first module of the station, known as thecore moduleor base block, was launched in 1986, and was followed by six further modules (Kvant-1(1987),Kvant-2(1989),Kristall(1990),Spektr(1995), thedocking module(1995) andPriroda(1996)), all launched byProtonrockets (with the exception of the docking module). When complete, the station consisted of seven pressurised modules and several unpressurised components. Power was provided by severalsolar arraysmounted directly on the modules. The station wasmaintained at an orbitbetween 296 km (184 mi) and 421 km (262 mi) altitude and travelled at an average speed of 27,700 km/h (17,200 mph), completing 15.7 Earth orbits per day.

Spacewalks (Extra-vehicular activities,or EVAs) in support of the operation of the station were major events in the assembly and maintenance of the orbital laboratory. EVAs were performed to install new components onto the station, to repair and replace various experiments, systems and equipment, and to install, monitor and retrieve scientific experiments. The first EVA carried out atMirwas held on 11 April 1987, whenEO-2crewmembersYury RomanenkoandAleksandr Laveykinassisted in the docking of theKvant-1module. The longest EVA was performed on 17 July 1990, whenEO-6crewmembersAnatoly SolovyevandAleksandr Balandinleft the station to repair their spacecraft,Soyuz TM-9,then encountered difficulties shutting the airlock hatch upon their return. The total time for that spacewalk was seven hours and sixteen minutes, close to the absolute limit of theirOrlan-DMAspacesuits.

In total, eighty EVAs were conducted aroundMirfrom 1987 to 2000. Sixty-three EVAs were conducted fromKvant-2'sairlock,fifteen from the core module's docking node (of which three were so-called 'intravehicular activities', or IVAs, withinSpektr), and two from the airlock of theSpace ShuttleAtlantis.
