Mir
Basic information
Space station that operated in low Earth orbit from 1986 to 2001, operated by the Soviet Union and later by Russia.
Between March 1987 and April 1996, five expansion modules were added to the core unit.
The journey of the 15-year-old Russian space station ended March 23, 2001, as Mir re-entered the Earth's atmosphere near Nadi, Fiji, and fell into the South Pacific.
It orbits at approximately 220 miles (350 km) above the Earth, and it travels at an average speed of 17,227 miles (27,724 km) per hour.
At the time it was the largest artificial satellite in orbit, succeeded by the International Space Station (ISS)
It hosted more than 100 people from 12 countries. It holds the record for the longest single human spaceflight, with Valeri Polyakov
