The International Space Station
The International Space Station (ISS) is a large spacecraft orbiting Earth, serving as a unique research laboratory where astronauts from around the world live and work. As highlighted in "Space Quest: Explore the Planets and Stars," the ISS enables scientific experiments in microgravity, advancing our understanding of space and life sciences. It also acts as a stepping stone for future missions to the Moon, Mars, and beyond, fostering international cooperation in space exploration.
