Astronauts on the International Space Station (ISS) live and work in a microgravity environment, conducting scientific research and maintaining the station. They perform experiments in various fields, such as life sciences, materials science, and fluid dynamics, taking advantage of the unique conditions of space to gain insights not possible on Earth. The ISS is equipped with laboratories and habitats, and astronauts use solar panels for power and rely on a continuous supply of essentials like air, water, and food, delivered by cargo spacecraft. Crews typically stay for about six months, with some missions lasting longer to study the effects of extended space travel.
