About International Space Station (ISS):

  • Overview:
    • The ISS is a modular space station launched in 1998, serving as a large laboratory in space where astronauts conduct experiments in microgravity.
  • Objective:
    • Conducts scientific research across various fields including astrobiology, astronomy, meteorology, and physics.
  • Key Facts:
    • Size and Orbit: Largest artificial object in space, orbits Earth approximately every 93 minutes at an altitude of 400 km.
    • Power Generation: Eight solar arrays generate about 160 kilowatts of power for station operations.
    • Participants: Multinational collaboration involving space agencies from the USA (NASA), Russia (Roscosmos), Japan (JAXA), Europe (ESA), and Canada (CSA).
  • Segments:
    • Divided into the Russian Orbital Segment (ROS) operated by Russia, and the United States Orbital Segment (USOS) managed by NASA and other international partners.
  • Ownership and Use:
