Satellites are artificial objects placed into orbit around celestial bodies, primarily Earth, to perform a variety of functions such as communication, weather monitoring, navigation, and scientific research. They are launched into space aboard rockets and can be positioned in different orbits, including Low Earth Orbit (LEO), Medium Earth Orbit (MEO), and Geostationary Orbit (GEO), each serving specific purposes. For example, communication satellites in GEO provide constant, stable coverage for broadcasting and internet services, while Earth observation satellites in LEO monitor climate, land use, and disaster response.
Satellites play a critical role in modern life, supporting applications like GPS navigation, military reconnaissance, and environmental monitoring. They help predict weather patterns, track storms, and provide real-time data to inform decision-making. Additionally, advancements in satellite technology have enabled the growth of commercial space ventures, making satellite deployment more accessible. The ongoing development of smaller, more affordable satellites (e.g., CubeSats) is also expanding their potential applications.
