Explanation:

The International Space Station (ISS) is a multi - national research facility in low Earth orbit. Its primary function is to conduct scientific research in various fields such as microgravity physics, biology, astronomy, and Earth observation. It is not designed to end wars, shield Earth from asteroids (that would require a different type of infrastructure), and while it does connect humans to space in a sense of enabling space exploration and research, its core and most comprehensive purpose is research.
