The International Space Station (ISS) is a modular space laboratory in low Earth orbit, jointly operated by NASA, Roscosmos, ESA, JAXA, and CSA. Launched beginning in 1998, it has been continuously inhabited since November 2000 and supports cutting-edge research in microgravity, Earth observation, and space technology, while fostering international cooperation.

Before there was the International Space Station, the reigning orbiting spaceport was Russia's Mir. Pictured above in 1995, the United States Space Shuttle Atlantis docked with the segmented Mir. During shuttle mission STS-71, astronauts answered questions from school students over amateur radio and performed science experiments aboard Spacelab. The Spacelab experiments helped to increase understanding of the effects of long-duration space flights on the human body. Last year, after 15 years of successful service, the decaying Mir space station broke up as it entered the Earth's atmosphere.
