What are the difference between the International Space Station and the Mir?

The International Space Station (ISS) is a collaborative effort involving multiple countries, including the U.S., Russia, Europe, Japan, and Canada, and it serves as a platform for scientific research and international cooperation. In contrast, Mir was a Soviet space station operated by the USSR from 1986 to 2001, primarily focused on Russian space research and operations. While both stations facilitated long-duration human spaceflight and experiments in microgravity, the ISS has a larger modular design and more advanced technology, making it a more versatile and sustainable platform for ongoing research. Additionally, the ISS is still operational, whereas Mir was decommissioned and re-entered Earth's atmosphere in 2001.
