NASA had a very old space station outside the earth named voyager 1. It shut down its camera on 14th February in 1990 just half an hour after recording and image which became special for the world.
The image was a blue dot that is quite pale and the whole dot is suspended in the beam of a lot of sunlight. The picture became poet famous and the small blue dot was the earth in real. The small blue colored spec has a background of the black emptiness which is the space.
In the picture, the earth looked alone and vulnerable in the whole world went crazy behind this photograph of the earth taken by Voyager 1. But right after taking this picture it closes down all of its camera and the recording equipment at that time.
Then after 30 years, the jet propulsion laboratory or JPL of NASA published a whole new version after revamping the portrait and it was quite breath-taking too.
They used some modern software by which the engineers in jet propulsion laboratory-processed the picture and also the data captured by Voyager 1 and turn them into three spectral filters which rebalanced the photo by changing the color channels.
It revealed some more details in the picture which was not seen there in the earlier stage and that is why people started believing that the picture is completely changed and updated.
The image was like the small picture of the earth in between a vast solar family.
In 1994 Sagan wrote on his book Pale Blue Dot “Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves”.
The earth looked so small even in the picture that when it was captured by Voyager 1, it occupied the space of only 0.12 pixels of space in it. So, it looks like that our earth is just a small and lonely speck in the greatest and the darkest galaxy.
It is quite fascinating for all of us who don’t know the technical details but quite mesmerized by the cosmic information.
This photo is a lifetime achievement for the scientists of NASA and that is why it should be preserved properly to show it to the next generation. Just by looking at this picture is a complete place for a science lover in that is why it is kept so lively in all these years.
That is one of the reasons why the scientists of NASA thought of redeveloping it properly after 30 long years. They are also working on other technical details by which they can preserve the work properly to help out the next missions guided by the next generation NASA scientist.
It will help them to understand the position of our planet in the solar system as well as to plan a whole new journey to this place to get some new data.
This fresh data will be the elements of progress in the cosmic study and also it will help us to know more about our planet in the coming era of science and Technology.
In his book, Sagan wrote “There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world,” And “To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we’ve ever known.”
