✅The ISS programme is a multi-national collaborative project between five participating space agencies:
🔸NASA (United States),
✅The ownership and use of the space station is established by intergovernmental treaties and agreements.
✅The ISS serves as a microgravity and space environment research laboratory in which scientific experiments are conducted in astrobiology, astronomy, meteorology, physics, and other fields.
✅The station is suited for testing the spacecraft systems and equipment required for possible future long-duration missions to the Moon and Mars.
✅It is the largest artificial object in space and the largest satellite in low Earth orbit, regularly visible to the naked eye from Earth's surface.
✅The ISS circles the Earth in roughly 93 minutes, completing 15.5 orbits per day
