The space shuttle Atlantis docked with the Russian spacecraft Mir in 1995. The historic rendezvous took place during NASA’s STS-71 mission, with docking completed on June 29, 1995.
Mir was a Russian—or, at the time, Russian-operated—space station launched in 1986. Its name means “peace” and “world” in Russian. Atlantis’s visit marked the first docking between a U.S. space shuttle and Mir, creating an important milestone in post-Cold War cooperation between NASA and Russia.
During the mission, Atlantis exchanged crew members with Mir, delivered supplies and equipment, and conducted joint operations while the two spacecraft traveled together in orbit. The shuttle undocked on July 4, 1995, and returned to Earth a few days later.
A common mix-up is the later STS-74 mission, also flown by Atlantis in November 1995. That mission docked with Mir as well, but carried a Russian-built docking module. The question’s reference to the first 1995 docking points to Mir itself, not the Kristall module or the later International Space Station.
