In the picture, Earth's apparent size is less than a pixel; the planet appears as a tiny dot against the vastness of area, amongst bands of sunlight reflected by the camera. A Reliable Source , which had actually completed its primary mission and was leaving the Solar System, was commanded by NASA to turn its electronic camera around and take one last picture of Earth throughout a fantastic area of space, at the demand of astronomer and author Carl Sagan.</p>
<br>
<p class="p__1">Background [edit] In September 1977, NASA released, a 722-kilogram (1,592 lb) robotic spacecraft on a mission to study the external Planetary system and ultimately interstellar space. After the encounter with the Jovian system in 1979 and the Saturnian system in 1980, the main mission was declared total in November of the same year.</p>
<br>
<p class="p__2">The spacecraft, still taking a trip at 64,000 km/h (40,000 mph), is the most remote human-made things from Earth and the first one to leave the Planetary system. Its objective has actually been extended and continues to this day, with the goal of examining the borders of the Solar System, including the Kuiper belt, the heliosphere and interstellar space.</p>

<p class="p__3">Voyager 1 was anticipated to work only through the Saturn encounter. When the spacecraft passed the planet in 1980, Sagan proposed the concept of the space probe taking one last image of Earth. He acknowledged that such a picture would not have had much scientific worth, as the Earth would appear too little for Voyager's video cameras to construct out any detail, but it would be meaningful as a perspective on humankind's location in the universe.</p>
<br>
<p class="p__4">It was not till 1989 that Sagan's idea was put into practice, but then instrument calibrations postponed the operation further, and the workers who developed and sent the radio commands to Voyager 1 were likewise being laid off or transferred to other tasks. Finally, NASA Administrator Richard Truly interceded to guarantee that the photograph was taken.</p>
