IntroductionWhat is satellite?Satellite is the moon, planets or a planet orbiting around a machine or stars. For example, the Earth is the satellite as it orbits the sun. So the moon, the moon is a satellite as it goes around the earth. Usually, the word "satellite" refers to a machine that has been launched into space and moves around the earth or other planets in space. The Earth and the Moon are examples of natural satellites. Thousands of artificial or man-made satellites orbit the earth. Some take photos of the planet to help meteorologists predict the weather and track hurricanes. Some photograph other planets, the sun, black holes, or distant galaxies. These images help scientists better understand the solar system and the universe. In addition to satellites, they can be used mainly for communications, such as TV and telephone signals, to all over the world. More than 20 satellite groups that make up the Global Positioning System, or GPS. If you have a GPS, satellites can help you understand your location. Why are satellites important? Satellites with extended scenarios allow them to see areas of the earth at a time. This capability means satellites can collect more data, faster than ground-based instruments. Satellites can also see into space better than telescopes on the Earth's surface. Because satellites fly above clouds, dust and molecules in the atmosphere can obstruct the view from the ground. Before pre-built satellites, TV signals couldn't travel far. TV signals only in straight line. They then immediately follow in space instead of following the curve of the earth. Sometimes mountains or tall buildings will block them. Phone calls to places that are too problematic. Lay telephone wires over long distances or in water... middle of paper... point to land and find information about clouds, oceans, land and ice. They also measure gases in the atmosphere, such as ozone and carbon dioxide, and the amount of energy the Earth absorbs and emits. And satellite monitoring of forest fires, volcanoes and their smoke. All the information helps scientists predict the weather and climate on Earth. This information also helps public health officials spot all diseases and famines: it helps farmers know which crops to plant and helps emergency workers respond to natural disasters. Observing the satellite in space has several tasks. Some observe harmful radiation coming from the sun. Explore asteroids and comets, the origin story of stars and other planets. Number of satellites orbiting near or flying towards another planet. Spacecraft could find evidence of water on Mars or capture objects near Saturn's ring.
