The first artificial satellites were launched in 1957. These satellites, known as Sputnik-I and Explorer 1, were designed to explore the universe. Since then, over 8,900 satellites have been launched from fifty countries. Of these, 5,000 remain in orbit and are currently operational. The remaining ones have been destroyed or have passed their useful lives and have now become space debris, circling in outer space until they are deconstructed.
Artificial Satellite :How does work?
Today, most artificial satellites operate in two distinct orbits: low Earth orbit and geostationary orbit. Generally speaking, the lowest Earth orbit is used for imaging and communication, while geostationary orbits are higher than this. Both low earth and geostationary orbit satellites use the power of gravity to help them remain in their orbits, but the lower earth orbit satellites are better suited for other purposes.
The geostationary orbit is the most common orbit for artificial satellites, although some are in lower earth orbits. These satellites are comparatively low above the ground, and must accelerate to maintain their orbits, balancing the force of gravity on the side. This makes them useful for taking pictures of the Earth, while high earth orbit satellites can communicate with each other and look at other regions. These two orbital systems are similar but differ in some important ways.
Artificial Satellite use
Artificial satellites help scientists monitor droughts, and they can also help determine the amount of food lost in a drought. They can also help scientists detect underground water reserves, which can be used to manage water resources. Because they are primarily solar-powered, they are more cost-effective and will save money in the long run. Despite their cost, artificial satellites will not last for ever. The cost of operating artificial satellites is higher than that of deploying them on the Earth, but they will also improve the quality of life in the planet.
Artificial satellites are important for scientific research. Their data can help scientists better understand droughts and estimate the amount of food that will be lost due to drought. Moreover, artificial satellites can help identify objects, such as the moon, and help distinguish between natural and artificial ones. The two types of satellites are geostationary and polar-orbiting. They are launched from the Earth and have different purposes.
Artificial Satellite Benefits
An artificial satellite is a man-made object launched into space. They orbit the Earth and may be crewed or uncrewed. A human-made satellite is also referred to as an earth satellite. Unlike natural satellites, which orbit the Earth in a circular path, a man-made satellite is uncrewed. Its existence is limited by the human race, but the idea of artificial satellites is still important for many reasons.
While there are more than a thousand natural satellites orbiting the Earth, there are about 1,000 artificial satellites that are operated by humans. In addition to Earth satellites, there are also a few human-made satellites. Some are crewed and others are uncrewed. However, they all serve a specific purpose. In this way, they provide vital information to the human race and the wider world.
The first artificial satellites were launched by the Soviet Union in 1957. The success of this project was critical to the development of the space program. They enabled humans to collect information about the planets beyond Earth. In addition to these, they helped scientists learn about the earth’s magnetic field, which affects the climate. Using these satellites, they are able to determine the location of various objects, such as satellites.
Today, artificial satellites are used to study the Earth and other planets, communicate with other people, and study the far-off Universe. The first artificial satellite was the Soviet Sputnik 1 mission. Other artificial satellites were developed later, including INSAT, IRS, and Kalpana-1. There are also military and scientific satellites. Aryabhatta was launched by the Indian government in 1975.
