ISS OBJECT TC

Mir was a space station operated in low Earth orbit from 1986 to 2001, first by the Soviet Union and later by the Russian Federation. Mir was the first modular space station and was assembled in orbit from 1986 to 1996. At the time it was the largest artificial satellite in orbit, only being succeeded by the International Space Station (ISS) after Mir's deorbiting in 2001. The station served as a microgravity research laboratory in which crews conducted experiments in biology, human biology, physics, astronomy, meteorology, and spacecraft systems with a goal of developing technologies required for permanent occupation of space.
