![]() ![]() It shows the location of the solar system with respect to 14 pulsars, whose precise periods are given. The drawing in the lower left-hand corner of the cover is the pulsar map previously sent as part of the plaques on Pioneers 10 and 11. ![]() A circle was used in this picture to ensure that the recipients use the correct ratio of horizontal to vertical height in picture reconstruction. Immediately below this is a replica of the first picture on the record to permit the recipients to verify that they are decoding the signals correctly. Immediately below this is a drawing of an entire picture raster, showing that there are 512 vertical lines in a complete picture. The drawing immediately below shows how these lines are to be drawn vertically, with staggered "interlace" to give the correct picture rendition. Picture lines 1, 2 and 3 are noted in binary numbers, and the duration of one of the "picture lines," about 8 milliseconds, is noted. The picture is made from this signal, which traces the picture as a series of vertical lines, similar to ordinary television (in which the picture is a series of horizontal lines). The top drawing shows the typical signal that occurs at the start of a picture. The information in the upper right-hand portion of the cover is designed to show how pictures are to be constructed from the recorded signals. Below this drawing is a side view of the record and stylus, with a binary number giving the time to play one side of the record - about an hour. ![]() The drawing indicates that the record should be played from the outside in. Written around it in binary arithmetic is the correct time of one rotation of the record, 3.6 seconds, expressed in time units of 0,70 billionths of a second, the time period associated with a fundamental transition of the hydrogen atom. The stylus is in the correct position to play the record from the beginning. The Golden Record Cover In the upper left-hand corner is an easily recognized drawing of the phonograph record and the stylus carried with it. The Voyager message is carried by a phonograph record, a 12-inch gold-plated copper disk containing sounds and images selected to portray the diversity of life and culture on Earth. With this example before them, NASA placed a more ambitious message aboard Voyager 1 and 2, a kind of time capsule, intended to communicate a story of our world to extraterrestrials. 1 T16:06:13-05:00 Patrick Timothy Dawson a0b08a5aaf9148250b99cba97af95de3340033d4 105 2 The Golden Record Pioneers 10 and 11, which preceded Voyager, both carried small metal plaques identifying their time and place of origin for the benefit of any other spacefarers that might find them in the distant future.
