International Space Station – UPSC Prelims

International Space Station:
  • The International Space Station (ISS) is a space station, or a habitable artificial satellite, in low Earth orbit.
  • Its first component launched into orbit in 1998, and the ISS is now the largest human-made body in low Earth orbit.
  • It circles the Earth in roughly 92 minutes and completes 15.5 orbits per day.
  • The ISS serves as a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology, and other fields.
  • Five different space agencies representing 15 countries built the $100-billion International Space Station and continue to operate it today.
  • The ISS programme is a joint project between five participating space agencies:
    • NASA (United States),
    • Roscosmos (Russia),
    • JAXA (Japan),
    • ESA (Europe), and
    •  CSA (Canada)
  • Its ownership and use has been established by intergovernmental treaties and agreements.
  • Continuous presence at ISS has resulted in the longest continuous human presence in low earth orbit.
  • It is expected to operate until 2030.
  • NASA plans to decommission it in 2031.
