Importance of Satellites

Satellites are elements that orbit around a certain celestial body. There are natural satellites and artificial satellites, that is, created by man to satisfy his needs. In the first case, a paradigmatic example is that of the moon, which revolves around the Earth and together with it makes a tour around the sun; in the second, we have the infinity of satellites that were created since the mid-twentieth century to carry out military, communications, investigation, etc. Certainly, in both cases there is a clear interest for man and this circumstance makes us appreciate its importance.

From the point of view of natural satellites, they have an influence on some natural phenomena that operate on the planets they orbit. In the case of our moon, it has an obvious relationship with the tides, a fact that has been known since remote antiquity. Fundamentally, this phenomenon is due to the attraction that the moon has on the surface of the water and that makes it cover larger or smaller portions of the coast depending on its position.

. The tides can affect fishing and they are also used for processes to obtain energy, situations that show their importance and the importance of our natural satellite.

However, from the perspective artificial satellites, they were developed in response to different problems that affect man. Their conception began to develop at the beginning of the 20th century and throughout the time deepened until it was possible in the second half of the last century to launch one's. The first satellite put into orbit corresponded to a project of the Soviet Union and this fact made The United States takes the space race seriously, managing shortly to also place its satellites own. hToday, this type of element is used for the most varied functions, highlighting among them the one related to the communication and the observation of the earth for the elaboration of maps, the geopositioning, etc.; research also makes use of them when they are used to more effectively observe other celestial bodies.

As we see, satellites have a great influence on our lives, whether we are referring to natural ones or artificial ones. In the latter case, without a doubt, we will see a large number of new variants in the future that will serve to significantly improve our quality of life.
