On STS-74, the Space Shuttle Atlantis undertook a vital mission to deliver the Mir Docking Module to the Russian space station Mir. Launched from Kennedy Space Center in Florida, the Atlantis lifted off at 3:50 PM EST, marking the fourth American mission to the Russian space station as part of the growing partnership in space exploration between the two nations. The Mir Docking Module was designed to allow American space shuttle missions to dock with Mir, paving the way for future collaborations in scientific research and international space missions.

The mission involved a diverse crew, including Commander Curt Brown, Pilot Steven Lindsey, Payload Commander John Lounge, and Mission Specialist Jerry Ross, among others. During the nine-day mission, Atlantis was successfully docked with Mir, and the crew conducted joint operations with Russian cosmonauts, enhancing the scientific community's ability to perform experiments in microgravity. The successful delivery of the docking module represented a pivotal moment at the height of the International Space Station (ISS) project, setting guidelines for future international collaboration.

Once in place, the module enabled various subsequent activities, including an extensive exchange of ideas and technology across borders. The endeavor highlighted not just technological prowess but also the cooperative spirit emerging in the post-Cold War era’s space exploration narrative. This kind of joint missions initiated by Atlantis's launch helped both countries share resources and knowledge, ultimately culminating in the ISS program, where nations contribute to ongoing space research.
