Astronomer Carl Sagan made a plea to NASA scientists in 1990, when the Voyager spacecraft launched from NASA crossed the boundaries of the solar system and entered interstellar space. He said, ‘Instruct Voyager to look back at Earth for once, please.’ NASA made that request, Voyager only looked back once. Then he took only one picture of the world. That picture was taken from a distance of 600 crore kilometers.
Those who have seen that picture know that there are a few lines of light in the middle of the vast darkness. A dirty point in the middle of it. In Sagan's words, 'Pail Blue Dot'. Yes, that point is the world inhabited by our 600 million people and ecological creatures. This picture reminded human civilization once again of how insignificant and insignificant the position of man is in the cosmic realm. People born from the ashes of stars therefore want to know about the greatness of the universe. How were the planets-stars-galaxies born? How did the Big Bang happen from just one point? Is the world really moving away, moment by moment? Can we ever go to a star? Do any of the stars that are burning like fireflies in the great darkness have a home like the earth in their world, where any intelligent creature lives? Thinking about this picture, he wrote Pail Blue Dot or the planet with the faded blue dot with the goal of the future of mankind in space.
At present, the global war on fossil fuels, greed, unbridled trade and our country's river occupation, land grabbing, traffic congestion, import of cars without political leadership tax seems like a faded world.
At the time, Voyager seemed to be crossing interstellar space beyond the boundaries of the solar system, but we didn't really know how far it was. Now confirmed, on December 16, 2004, 94 astronomical units (average distance from the Sun to the Earth) crossed the Helios and entered Heliopase. On August 25, 2012, Voyager 1 crossed the heliopause and entered interstellar space. This journey will continue till 2025 if the power generating radio isotope generator is active. Voyager seems to be moving forward to expand the cosmic vision of mankind. Another thing was learned from the science journal Science published while the spacecraft was on the edge of the solar system. At that time, NASA Voyager mission project scientist. Edston said, "I don't know exactly when the Voyager 1 spacecraft will leave the solar system, but I believe that moment is near. It could happen any day, it could take years. 'Now it's real. If that is the case, then it takes 10 hours at the speed of light to travel from one end of the solar system to the other. It took Voyager 35 years.
Voyager 1 was launched on September 5, 1986. The 622-kilogram robotic spacecraft began its mission to study the outer regions of the solar system. The spacecraft encountered the planetary system Jupiter in 1979 and Saturn in 1970. Meanwhile, in 2015, Voyager-1 found a new level on the last frontier of the solar system. About 1.1 billion miles from Earth. Scientists have dubbed it the 'Magnetic Highway'. As of November 2017, Voyager 1 has been in operation for almost 39 years, two months and 16 days and is still communicating with the Earth through messages sent from deep space. It currently takes about 18 hours for information to come to the world from Voyager-1. This is the farthest man-made device or spacecraft from Earth — about 138 astronomical units or 1,264.10 million miles.
In his 1994 Pail Blue Dot Planet: A Vision of the Human Future in Space, Carl Sagan expressed his thoughts on the image of a point taken from a distance of 600 million kilometers. At great distances, he said, the earth does not seem to be anything more than a point. But just thinking about it makes us feel very different. Because it involves our existence. This is the world, this is our home, this is us. Everyone I love, everyone I know, is here. At least everyone we've heard of has lived here. Thousands of sufferings, thousands of religions, ideologies and economic doctrines throughout our lives; As many hunters and plunderers, as many brave-cowards, as many destroyers of civilization, as many kings and subjects, as many lovers, as many parents, as many dreamy children, explorers, travelers, as many moral teachers, as many corrupt politicians, as many superstars, of history All the saints and sinners, all of them have spent their lives in that little dust floating in the light. Our world is a very small stage in the huge universe.
One has to wonder how much blood the generals and emperors have shed in the hope of becoming great by conquering a small part of this small point. Think of the limitless violence; The smaller this point the more a small part of the people say will conquer the other end.
What is the conflict between them, what is their thirst for blood? What is the manifestation of their jealousy? Our nose is high, our imaginary egoism, we are in the moon .
