What do they do on the international space station?

On the International Space Station (ISS), astronauts conduct scientific research and experiments across various fields, including Biology, physics, and materials science, in a microgravity environment. They also perform maintenance and upgrades on the station's systems and engage in educational outreach activities. Additionally, the ISS serves as a platform for international collaboration in space exploration and technology development. Astronauts also engage in physical exercise to counteract the effects of prolonged weightlessness on their bodies.
