The Mir space station was deliberately deorbited and destroyed in Earth’s atmosphere in 2001 after about 15 years in orbit.

Quick history

  • Mir was launched by the Soviet Union in 1986 as a modular space station and later operated by Russia after the USSR collapsed.
  • It became the first long‑term, permanently crewed space station and hosted more than 100 visitors from around a dozen countries.

Why it was retired

  • By the late 1990s, Mir was old, had suffered failures, a serious onboard fire, and even a collision with a Progress resupply ship in 1997 that damaged one module.
  • Russia faced high maintenance costs and shifted funding and focus to the International Space Station, making Mir’s continued operation hard to justify.

How it came down

  • Mir was deorbited in a controlled way on 23 March 2001: its orbit was gradually lowered, then final engine burns sent it into the atmosphere.
  • Most of the station burned up over the South Pacific, with remaining fragments falling into a remote ocean area far from populated regions.

What Mir left behind

  • Mir proved humans could live and work in space for many months at a time, including record stays like Valery Polyakov’s 438 continuous days in orbit.
  • Lessons from Mir’s engineering problems, safety incidents, and international missions fed directly into the design and operations of the International Space Station.
