The International Space Station (ISS) stands as a testament to global collaboration in manned spaceflight. Orbiting Earth at approximately 28,000 kilometers per hour, the ISS serves as a research laboratory, allowing scientists to conduct experiments in microgravity that are impossible on Earth. Its continuous occupation by astronauts from multiple countries underscores the importance of international cooperation in space exploration. The ISS has facilitated advancements in medicine, material science, and Earth observation, setting the stage for future manned missions to the Moon and Mars.
