Over the next decade additional modules were sent aloft on separate launch vehicles and attached to the core unit, creating a large habitat that served as a versatile space laboratory for more than 14 years.
Mir (Russian: “Peace” or “World”) was the third generation of space stations developed by the Soviet Union. Its core module resembled its simpler predecessors in the Salyut series but had additional docking ports (a total of six) that accommodated not only a succession of manned spacecraft and cargo ferries but also permanently attached expansion modules equipped for scientific research.

[Credit: Encyclopædia Britannica, Inc.]Mir’s core module was launched on Feb. 20, 1986. It had the form of a stepped cylinder about 13 metres (43 feet) long and 4.2 metres (13.8 feet) in diameter at its widest point. The module had a docking port at each end and four ports sited radially at its forward end. On March 13, 1986, cosmonauts Leonid Kizim and Vladimir Solovyov were sent aloft aboard a Soyuz T spacecraft to rendezvous with Mir and become its first occupants. Between March 1987 and April 1996, five expansion modules were added to the core unit Kvant 1 (1987), an astrophysics observatory; Kvant 2 (1989), containing supplementary life-support equipment and a large airlock; Kristall (1990), a materials-sciences laboratory; and Spektr (1995) and Priroda (1996), two science modules containing remote-sensing instruments for ecological and environmental studies of Earth. With the exception of its first occupants, Mir’s cosmonaut crews traveled between the station and Earth in upgraded Soyuz TM spacecraft, and supplies were transported by robotic Progress cargo ferries.

Mir supported human habitation from March 14, 1986, to June 15, 2000, which included an uninterrupted stretch of occupancy of almost 10 years. It hosted more than 100 people from 12 countries, including a series of U.S. astronauts in 1995–98 as part of a Mir–space shuttle cooperative endeavour. Between January 1994 and March 1995, Mir cosmonaut-physician Valery Polyakov set an endurance record of 438 continuous days in space, longer than the approximately nine months estimated for a manned voyage to the planet Mars.
Designed for only a five-year life, the aging Mir suffered a series of equipment failures and accidents in 1996–97 but remained in service. On March 23, 2001, the abandoned Mir made a controlled reentry, with the surviving pieces falling into the Pacific Ocean. (See also Energia.)
A chronology of missions to Mir is shown in the table.
