A satellite is a moon, planet, or machine orbiting a planet or star. For example, the Earth is a cable because it revolves around the Sun. Likewise, the Moon is a satellite since it revolves around the Earth. Typically the word “satellite” refers to a machine thrown into interstellar and orbits the Earth or another body in space.
The Earth and the Moon are samples of natural satellites. Thousands of artificial or artificial satellites revolve around the Earth. Some take pictures of the Earth to help meteorologists predict the weather and track hurricanes. Others photograph other planets, the Sun, black holes, dark matter, or distant galaxies. These images will help scientists better understand the solar system and the universe.
Other satellites are mainly used for communications, such as TV signals and phone calls around the world. A group of more than 20 cables forms the Global Location System or GPS. If you have a GPS telephone, these satellites can help you determine your exact location.
Why are Satellites Necessary?
A bird’s eye view from satellites allows them to see large tracts of land simultaneously. This capability means that satellites can collect more data faster than ground-based instruments.
Satellites can also see space better than telescopes on the Earth’s surface. Due to the detail, satellites fly over clouds, dust, and molecules in the atmosphere, which can block your view from the ground.
In front of the satellites, television signals did not go very far. Television signals are transmitted only over a direct line. As a result, instead of following the curvature of the Earth, they drifted rapidly through space. Sometimes they were blocked by mountains or tall buildings. Telephone calls to remote locations were also a problem. Laying telephone cables over long distances or underwater is complex and very expensive.
Through satellites, TV signals and phone calls are sent to the satellite. Then the satellite can almost suddenly send them back to different places on Earth.
What are The Parts of The Cable?
Satellites come in all shapes and sizes. But most have at least two things in common: the antenna and the power supply. The antenna often sends and receives information to and from the ground. The power source can be a cosmic panel or a battery. Solar panels produce energy by converting sunlight into electricity.
Many NASA satellites are equipped with science cameras and sensors. Sometimes, these tools are sent to the ground to collect land, air, and water information. They sometimes fly in space to collect data about the solar system and the universe.
How do Satellites Revolve Around The Earth?
Most satellites are launched into space using rockets. A satellite orbits the Earth when the Earth’s gravitational pull balances its speed. Without this balance, the satellite would fly straight into space or crash to Earth. Satellites revolve around the Earth at different heights, rates, and orbits. The two most common types of orbits are geostationary and polar.
A geostationary satellite flies over the equator from west to east. It moves on the same track and at the same speed as the Earth. A geostationary satellite appears stationary from Earth because it is always over the exact location.
Satellites in polar orbit travel from pole to pole in a north-south direction. When the Earth rotates below, these satellites can span the entire globe, one swath at a time.
Why don’t Satellites Collide?
You can. NASA and the other US and international organizations track satellites in space. Collisions are rare because a satellite put into an orbit that should avoid other satellites during launch. And also, But eye sockets can change over time. And the likelihood of a collision increases with the number of satellites launched into space.
In February 2009, two communications satellites collided in space – an American and a Russian. However, it believed that this will the first time that two artificial satellites accidentally collide.
