Launched on March 2, 1972, Pioneer 10 … With a three week deadline Carl Sagan knew that there would be no time for negotiating with such a large bureaucracy. The radiating lines at left represents the positions of 14 pulsars, a cosmic source of radio energy, arranged to indicate our sun as the home star of our civilization.

(Hopefully, any aliens reading the plaque will not use this knowledge to immediately invade Earth.) When hydrogen atoms change states, electromagnetic radiation is released. Sagan had been approached by two people who had heard that Pioneer 10 was set to be the first spacecraft to ever leave the solar system and they had come up with an idea of sending a message out with it.

Arguably the most important part of the plaque it was, however, a very difficult part to deal with. These pictures are intended to communicate very specific stories to anyone or anything Pioneer 10 might come across in it’s voyage across the galaxy. According to The Planetary Society, founded by Sagan, the idea for the plaque was suggested to him just a few months before the launch of Pioneer 10. In the years since it’s launch there’s been both praise and criticism towards the design of the plaque. The plaque shows a woman standing eight of these hydrogen units tall, or five feet five inches tall. Designed by Carl Sagan and Frank Drake and illustrated by Linda Salzman Sagan, the plaques sported images detailing the location of Earth within the galaxy as well as images of a human woman and man. Another batch will be produced by a laser-engraving machine and start at $99.

They assumed that the common language between both us and the aliens are based on science and math. The "1-" symbols at the ends of the lines are binary numbers that represent the frequencies of these pulsars at the time of launch of Pioneer F relative of that to the hydrogen atom shown at the upper left with a "1" unity symbol. The hydrogen atom is thus used as a "universal clock," and the regular decrease in the frequencies of the pulsars will enable another civilization to determine the time that has elapsed since Pioneer F was launched. actually I have heard about this in the past in one of my classes, but we didnt go deeper in this subject, I certainly keeping this post saved! It was launched in 1972 and began photographing Jupiter from November, 1973. In the upper left of the plaque is an image of hydrogen atoms in two energy states—a universal constant for space and time. And this wave of radiation is the basis for measurement for the rest of the plaque: The radiation lasts 0.7 nanoseconds (basis for time) and extends roughly 21 centimeters (basis for length). After finding a documentary about the image’s creation, he realized the man who made them might still be around. I’ve always loved the story of the Pioneer Plaque and was really happy to finally add it to the blog. Is Slender Man Real?

Personally I think Carl Sagan and all the other people who worked on the project did a great job with it and navigated some amazingly tough problems and situations with grace. The existence of the plaque was then announced to the public in the remaining days before launch. Some people say that the pictures were too simplistic, or should have included this or that particular detail, or that aliens would never understand such a thing. King teamed up with engraver Ponciano Barbosa at Precision Engravers in San Carlos, California, to produce the images. Naysayers of the plaque tended to be people of the conservative variety (many of the loudest were politicians) who said that the whole thing was pornographic and ‘Sending smut to the stars‘. Humans. Cookie Policy It was only through the efforts of someone as dedicated and charismatic as Carl Sagan that it even had a remote chance of being approved by NASA administrators. Thanks Nairim I appreciate it :).
