In view are four cylindrical modules covered in white insulation arranged in a cross shape about a small, central sphere. Another module projects backward from this sphere, and a small module is attached to the far end of that. Each module is sprouting various solar arrays, cranes and other spindly equipment, with Soyuz and Progress spacecraft docked to the forward and aft ports of the complex.]]
Mir (, ; lit. Peace or World) was a Soviet and later Russian space station, operational in low Earth orbit from 1986 to 2001.
With a mass greater than that of any previous space station, Mir was constructed from 1986 to 1996 with a modular design, the first to be assembled in this way. The station was the largest artificial satellite orbiting the Earth until its deorbit on 21 March 2001, a record now surpassed by the International Space Station (ISS). Mir served as a microgravity research laboratory in which crews conducted experiments in biology, human biology, physics, astronomy, meteorology and spacecraft systems in order to develop technologies required for the permanent occupation of space.
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 at Mir was held on 11 April 1987, when EO-2 crewmembers Yury Romanenko and Aleksandr Laveykin assisted in the docking of the Kvant-1 module. The longest EVA was performed on 17 July 1990, when EO-6 crewmembers Anatoly Solovyev and Aleksandr Balandin left 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 their Orlan-DMA spacesuits.
