aScientists of the US space agency NASA have recently informed that Parker Solar Probe, launched in 2018 with the aim of solving the mysteries of the Sun, has succeeded in touching or touching the Sun. Parker is the only man-made machine to get so close to the Sun. According to Professor Justin Kasper at the University of Michigan, ‘the first and most dramatic time was when Parker was under the sun’s outer atmosphere (corona) for 5 hours’. Parker’s meeting with the sun is an incredible and extraordinary record in the field of space science.
the star that gives life to the earth
Man has been familiar with the Sun since ancient times. Primitive humans must have observed that the sun rises regularly in the morning and sets in the evening. Primitive humans must have also guessed that if the sun does not rise, then black darkness will prevail and everything will become black and cold and this will also end human life. Therefore, the people of ancient times started worshiping the Sun by giving it the status of a deity.
Thanks to scientific advances, we know today that the Sun is a common, but very important star with a deep connection to daily life. Although still in the eyes of the general public, the sun is a huge ball of blazing fire hanging in the sky, a symbol of faith. However, the light coming from this star gives life to our earth. Therefore, if the Sun is called the real deity of the earth, then it will not be an exaggeration.
If someone is asked this question, which is the nearest star to us, then he starts speculating. Although the Sun is still a god in the eyes of the common people, but when the secrets of the Sun were revealed, it was found that the Sun is an ordinary star out of about 200 billion stars present in our Milky Way galaxy. However, the Sun appears much brighter than the rest of the stars because it is closer to the Earth than the rest of the stars. But its proximity makes it the most important star. Scientists have taken full advantage of this proximity to the Sun.
After years of research and observation, scientists have gathered many important information related to the Sun, through which the structure of the Sun can be understood properly. Research related to the Sun has made great progress today, with the help of which scientists are able to understand the relationship between the Sun and the Earth. But we still do not understand correctly those parts of the Sun that are not directly visible from Earth. Because of this, many mysteries related to the Sun are still unsolved.
Scientists have been trying for the last five-six decades to unveil the secrets of the Sun. For this, many satellite-spacecraft have also been launched in space. But Parker Solar Probe is completely different from them in the sense that it is studying very close to the Sun.
an unprecedented space mission
NASA on 12 August 2018 from Cape Canaveral, Florida on a Delta-4 Heavy rocket launched a mission that has never happened before – ‘Parker Solar Probe Mission’, aimed at deep understanding of the Sun’s atmosphere. The Sun’s brilliance, extreme temperatures, and the magnetic field created around it limit scientists’ access, the Parker Probe was sent to tackle these challenges.
Parker entered the Sun’s outer atmosphere (Corona) on April 28 this year after traveling 150 million kilometers, passing through the solar system at a speed of 7 lakh kilometers per hour. Now about seven and a half months later, after analyzing the data received from the vehicle, NASA scientists have made this information public at the recent meeting of the American Geophysical Union.
A masterpiece of state-of-the-art thermal engineering
The temperature of the corona, the outermost atmosphere of the Sun, is about 11 lakh degrees Celsius and the temperature inside is in millions of degrees Celsius! Such extreme temperatures can melt everything found on Earth in a few seconds, so to counter this scorching heat, Parker has heat shields made of carbon composite foam material 11 and a half centimeters thick between two carbon fiber sheets of 2.4 meters. have been used and these shields have been painted white to reflect the sunlight.
Saving Parker’s instruments from burning out from the scorching heat of the sun was a great challenge for scientists. Therefore, its instruments are made from a mixture of metals with high melting point or high melting point such as – tungsten, rhenium niobium, sapphire, molybdenum, chromium etc. Parker has become an unmatched specimen of state-of-the-art thermal engineering due to these characteristics.
Fastest flying space probeParker is the fastest flying space probe in history. Its speed is 4 lakh 30 thousand miles per hour. This means that Parker is able to cover the distance from Kashmir to Kanyakumari 242 times in just one second! Parker will travel around the Sun 24 times and visit Venus 7 times during his seven-year lifetime. The last encounter with Venus and the 8th trip to the Sun brought Parker closer to the Sun.
After this, when the data gathered by Parker was analyzed, it was found that the probe has managed to touch or touch the outer atmosphere (corona) of the Sun. Then its distance was only 79 lakh kilometers from the surface of the Sun. “The fact that Parker touched down on the Sun is a momentous moment for solar science and an unforgettable achievement,” said Thomas Zurbushen, associate administrator for NASA’s Science Mission Board.
Parker completed his 10th voyage around the Sun last month. Parker will be very close to the surface of the Sun in 2025. In 2025, its distance from the surface of the Sun will be about 43 lakh kilometers. After this, NASA has not given any information about what will happen to this space probe weighing 612 kg and 9 feet 10 inches long.
What will be achieved by this mission,
Parker’s purpose is to know and understand the relationship between the Sun and the Earth. It is especially studying those aspects of the Sun, which directly or indirectly affect the life and society of us Earthlings. At the same time, by keeping a constant eye on the Sun, it is helping scientists to solve many of its mysteries. Broadly, the goal of this mission is to study the physical study of the Sun’s outer atmosphere (corona), solar storms, the Sun’s magnetic field and its effects on the Earth’s atmosphere.
The sun not only gives light and heat to run life smoothly, but it also gives us an invisible flow of solar material. This invisible flow includes charged particles, high energy electromagnetic radiation and strong magnetic field lines, which are known as ‘solar storms’ or solar storms.
Our Earth’s upper atmosphere and its protective magnetic field are constantly exposed to solar storms, which have a profound effect on our communication systems (GPS, Internet, etc.) and electrical services, which can even cause these systems and services to stop. Huh! With Parker’s help, scientists want to research solar storms. This can help in taking precautions to protect astronauts, satellites, communication services and power grids. In reality!
