Satellites orbit the Earth and collect critical data for both research and practical applications. In scientific research, they monitor climate patterns, track natural disasters, and study oceans, forests, and atmospheric conditions. Satellites also contribute to astronomy by observing celestial bodies without atmospheric interference. In daily life, they support GPS navigation, satellite television, internet connectivity, and weather forecasting. By relaying real-time information across the globe, satellites enable accurate predictions, disaster management, and communications in remote areas. Their dual role in scientific understanding and practical applications makes them indispensable to modern society.
