A satellite is a man-made object that orbits around the Earth or another celestial body. Satellites come in many shapes and sizes, depending on their mission. Some send back valuable data to scientists while others are used for communication or entertainment purposes. The first artificial satellite was launched into space in 1957 by the Soviet Union. Since then, hundreds of satellites have been sent into orbit for various reasons. Satellites can be either geostationary or low earth orbiting (LEO). Geostationary satellites remain at a fixed position relative to the surface of the planet, whereas LEOs travel much closer to the Earth’s surface and move around it rapidly. Many weather satellites are stationed in geostationary orbit because they need to take continuous pictures of large areas of land from one location; this type of positioning allows them to do so without moving too far away from their assigned area over time due to its high altitude above the Earth’s surface. Communication satellites enable long-distance transmission of signals such as radio, television, telephone calls and internet connections across vast distances between two points on Earth; these signals are transmitted via microwaves which bounce off mirrors located on board each satellite and reach receivers located at both ends within seconds ” a process called ‘bouncing’ light waves off an atmospheric layer known as ionosphere helps boost signal strength further when necessary. Spysats are also often used by government organizations for surveillance missions; recent examples include USA’s Keyhole series which were designed specifically for monitoring activity from outer space during times of war or other crises situations worldwide. Navigation systems such as Global Positioning System (GPS) rely heavily on dozens of strategically placed navigation satellites positioned all around our planet providing accurate information about locations anywhere geographically speaking – this technology has revolutionized transportation industry allowing drivers pinpoint exact routes without getting lost anymore. In conclusion, there are numerous types/uses of satellites orbiting our planet today with new ones being added regularly thanks advances made in aerospace engineering field every day – they play an essential role helping us understand more about universe itself while providing invaluable services here down below right where we live.
