Greetings esteemed guests from the 18th century! Welcome to the International Space Station, or ISS, a remarkable scientific marvel of your future. Here in the vastness of space, representatives from multiple nations collaborate on groundbreaking research and experiments. The ISS serves as a laboratory and living quarters, while orbiting Earth at an altitude of approximately 420 kilometers. Remarkably, the station travels at a speed of 28,000 kilometers per hour. We conduct experiments in many fields, such as physics, biology, and astronomy, to better understand our universe and enhance life on Earth. The knowledge gained here benefits many aspects of human existence, from medicine to technology. Think of the ISS as a symbol of unity and hope for future generations!
