Before discussing the satellite missions, it is necessary to know about the satellites. Actually, a satellite can be a natural one as the moon or an artificial one, which is a man-made machine which orbits a certain planet or star. Now the key feature of a satellite is the orbiting quality. For example, the earth orbits the sun, so it is a satellite. Generally, a satellite indicates a machine that is accurately launched into space so that it can orbit the earth or another different body in space.
The fact is currently a good number of satellites are present in the space that moves around the earth.
Now every satellite has to perform a specific task. And performing the task means to complete a mission. Actually, a mission means to prepare a strategy or plan to fulfill a specific task.
Facts and benefits about satellite missions: as already mentioned, every satellite has a specific mission. There are several different tasks that an artificial satellite has to perform to acquire many benefits.
Weather information: Some satellites take pictures of the earth from space to gather weather information. Currently, the meteorologists can predict properly about the weather. With proper satellite pictures, it is possible to know earlier about the rain and storm. Countries of the Asian continent can have a great facility regarding the agriculture from the satellite pictures. Even proper images of the wind can predict the mode of a hurricane.
Collect information about different planets of the solar system: Some satellites are launched to read the actual condition of different planets of the solar system. Previously and recent missions are prepared to explore the unknown mysteries of the red planet of the solar system, that is Mars. The key search for this kind of mission is to see if there is any evidence of life on the different planets of the solar system. Even they search for the atmospheric condition of those planets, so that if it is possible to create future shelters for the human civilization. Recently the EUROPEAN SPACE AGENCY has launched a satellite mission that is mainly related to the Mars mission. Apart from the existence of life, satellite missions also cover the many other important factors of the planets of the solar system.
Collect information about the sun: Some satellite missions are conducted to explore the unknown facts about the sun. For a long time research has been going on and different space agencies have already conducted several satellite missions. So far extensive research is going on about the magnetic field of the sun. And many successful satellite missions have already discovered many important facts regarding the satellite missions.
Create good signals: Apart from these missions, another very essential satellite mission is to create a good communication signal. How to track a phone number? That means the better satellite signal provides better TV signals, better phone signals.
So, it is true that there is a great importance of the satellite missions. Through satellite missions, many essential activities can be performed, and various unknown facts can be explored easily. Through satellite, it is easy to get images of large areas of the earth at one time. And this ability helps you to collect more data than the instruments on the earth. So, in a word, satellite missions are truly very helpful to explore so many unknown facts of the universe and the solar system.
Sputnik is the name related to many adventures and histories. It was the very first artificial satellite launched from the earth. Currently, there are many documents and research reports, even many live videos and images are also found. But when Sputnik 1 was launched, that time it is absolutely difficult to gather a single video or image. And so, the curiosity of the common man was very high. Now apart from this curiosity, the mission of Sputnik 1 is also very important. With the launch of this satellite, the scientist had proved one fact that truly the impossible word is now an obsolete word. Many key facts were discovered from the journey of the satellite. So, Sputnik 1 is the evidence of the unique creation and achievement of the human civilization.
Now when you are discussing the satellite, then it is necessary to explore various facts regarding the Sputnik 1.
The facts are:
First satellite: Sputnik 1 is regarded as the “Elementary Satellite 1” from the Russian perspective. It was launched into space by the Soviet Union on 4th October in 1957. It was placed in an orbit elliptical to the Earth. The orbit is actually a low orbit of the earth.
Unique structure: The structure of this satellite is truly unique. It consists of a diameter of 58 come with completely polished and a metal look. The body also contains four very powerful radio antennas to throw or broadcast the essential radio pulses. The key feature of this satellite was that it was noticeable from every corner of the earth with the radio pulses being detectable from any part of the earth.
Generate competition: One key fact regarding this development was the introduction of the competition between the major powerful countries who had not yet achieved this space development. Also, with this launch major changes took place in the technological, scientific, even military and political arenas of the world.
Send radio signals: Not equipped with the current modern sensors this satellite still served the best by sending information about the upper layers of the atmosphere of the earth and the ionosphere. Actually, the radio signals with its unique calculation provided some very important information regarding the ionosphere. It is true that as the satellite was devoid of any kind of sensors, so it was difficult to study all the information from the earth.
The time of the launch: International Geophysical Year was the actual time when Sputnik 1 was launched from the site at 5th Tyuratam range, presently known as the Baikonur Cosmodrome. The speed of the satellite was unique. It traveled the whole path with a speed of 29.000 km/hour. This speed took 96.2 minutes for covering one orbit. The rate of transmission was between the range 20.005 – 40.002 MHz, and the amateur radio monitored the complete thing. The transmission lasted 21 days, and on 26th October in 1957 it stopped when the batteries of the transmitter ran out permanently. On 4th January in 1958 the satellite got burnt at the time of re-entering into the atmosphere of the earth.
So, the amazing satellite, Sputnik 1 completed 70m km path and stayed in orbit for about three months.
