1 Feb 1990 the spacecraft Voyager 1 has received a command to turn, to make the legendary photo of our planet. Exactly 30 years ago, on 14 February 1990 the world saw the pale blue dot, suspended in the rays of the Sun. Camera of Voyager-1 made a series of 60 images that were used to create the first “family portrait” of our Solar system. Today, NASA in conjunction with Jet Propulsion Laboratory provided an improved version of “Pale blue dot”, using modern software and methods of image processing. About it on the official website of NASA officials at the Agency.
Last look at our planet
Robotic spacecraft Voyager-1 and Voyager-2 were launched from Cape Canaveral in 1977. Initially, the mission of Voyager was to explore the gas giants Jupiter and Saturn, however, both devices are now 42 cut through the vastness of space. Read more about what happened to Voyager in four decades, read our special article. Today, both spacecraft are up to 4 times further from the Earth than February 1, 1990. When Voyager 1 got the team to turn around, to take photos of the Earth, NASA experts were aware of the fact that both devices are no longer to bond with other objects. Immediately after the pictures were taken, began a gradual shutdown devices and other systems on both probes. Through these processes, the devices retain the performance so far.

Working to improve the quality of the original image was conducted under the supervision of experts — planetary scientist candy Hansen and engineer William Mcmannama. Both specialists helped to edit the source image. As a result, the color photography has undergone significant changes. As writes The Universe Today, the use of special software, Photoshop and Lightroom allowed to get rid of false colors. However, the main purpose of processing “Pale blue dot” was the reduction of grain size and increase in scale. So, in the new version of the image, the Earth is only 0.12 pixel.
When the probe Voyager 1 took this amazing shot, it was outside of Neptune at a distance of 6 billion kilometers from the Sun. That’s what about this picture he wrote in his eponymous book, the astronomer Carl Sagan:
“Look again at that dot. Here it is. This is our home. We. Everyone you love, everyone you know, everyone you ever heard, all that has ever existed people have lived their lives on it. Many of our pleasures and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every Creator and destroyer of civilizations, every king and peasant, every couple in love, every mother and every father, every capable child, inventor and Explorer, every teacher of ethics, every lying politician, every “superstar,” every “greatest leader”, every Saint and sinner in the history of our species lived there — on a mote, suspended in a sunbeam… it is Our duty to be kinder to each other, and to preserve and cherish the pale blue dot, our only home”.
