Navigation Bar Frequently Asked Questions Voyager 2, is it planned to ever reach Pluto? Both Voyagers flew beyond the orbit of Pluto/Neptune in 1989, but neither flew by Pluto, which was elsewhere in its orbit at the time. It was never planned that the Voyagers would visit Pluto. The original mission of Voyager was to explore Jupiter and Saturn. Two spacecraft were sent on slightly different paths, first to Jupiter and then, with gravity assists, on to Saturn. Voyager 1 could have been aimed on to Pluto, but exploration of Titan and the rings of Saturn was a primary scientific objective. This caused the trajectory to be diverted upward out of the ecliptic plane such that no further planetary encounters were possible for Voyager 1 Once Voyager 1 had successfully gathered data at Titan, Voyager 2 was allowed to go on to Uranus and Neptune. Voyager 2, theoretically, could have been aimed for Pluto, but the aim point would have been inside the planet of Neptune - not very practical. So Pluto was the only outer planet the Voyagers didn't visit. When we send spacecraft through the asteroid belt to the outer planets, how do we navigate the craft through the belt? Pioneers 10 and 11 had preceded the Voyagers to Jupiter and the asteroid belt was a major concern for them. By the 1960's more than 3000 minor planets had been discovered and their orbits well determined. Even 50,000 minor bodies spread over the volume of space occupied by the asteroid belt would produce little direct danger, although a chance collision with an uncatalogued object was possible. "While the largest of the asteroids were known and their orbits charted, many of the asteroids moved in unknown orbits. Although the risk of a spacecraft colliding with a charted asteroid was negligible, there was no way to estimate how many particles the size of a grain of sand might be present in the asteroid belt to collide with the spacecraft and seriously damage it". Carl Sagan's biography recently and I came across an interesting incident when Dr Sagan persuaded NASA administrators to turn one of the Voyager space probes around in order to take a last image of the solar system, which apparently included an image of the sun, from the edge of the solar system. I have tried to search for this image on the JPL Voyager website but I could not find it. Would you be so kind as to direct me to any site where this image might be displayed? I saw an image on the History Channel that they said was taken by one of the Voyager craft; it was an image of the Solar System taken from beyond Pluto. Can you tell me if this photo does exist and where I might find a copy of it? I think you are referring to the series of photos taken by Voyager 1 on Valentine's Day 1990. These were the final images taken by either of the Voyager spacecraft. You can view the "Portrait of the Solar System" as well as Voyager pictures of Earth, Jupiter, Saturn, Uranus and Neptune at the Planetary Photojournal.
Then select Voyager 1 or Voyager 2 and submit the query. There are several pages of images, so you should choose NEXT SET until you find the thumbnail portrait you want. Once you click on a thumbnail, you will get an enlarged image, the original caption that accompanied the picture when released, instructions for downloading, and information for purchasing pictures. I have been searching and searching and can not locate a copy of the Murmurs of Earth CD. Would you know of a vendor that might sell copies of it? I am looking for a copy of the music that is onboard the Voyager. Are there plans to make the music available for downloading later? Are there copyright problems with the music, which is why they can't be downloaded? There was a book and CDROM published by Warner New Media in 1992. The book was a reprint of the Carl Sagan, et al, "Murmurs of Earth" that was originally published in 1978. Carl Sagan and his colleagues did the assemblage of the information on the Voyager Golden Phonograph Record. Most of the material they used was copyrighted by the creators/owners and Sagan had to get copyright releases in order to assemble the original record. Subsequently, Warner Multimedia was able to obtain copyright releases for the 1992 version of "Murmurs of Earth", by Carl Sagan, et al and included all the sounds and songs on the CDROM set that accompanied the Warner New Media release of the book.
gov) only that information for which we were able to get release, that's why everything, especially the music and the photos, is not there. Unfortunately, the book and CDROM are no longer being published and are hard to find as a set. Your best bet to find one quickly may be in a public or university library or at a used bookstore.
com/ and search on: Author: Carl Sagan Title: Murmurs of Earth You can find many instances where the book is for sale at prices around $40 US or less (most less than $20), but few (if any) include the CDROM. I'm writing a paper about the Golden Records that are aboard the Voyager spacecraft.
In addition to these, Sagan also organized a small group of scientific consultants to provide advice on the message contents. They all worked in the US, but their citizenship was not described in the book, Murmurs of Earth. If there was intelligent life in our infinite universe and they were not a peace loving species. Wouldn't the information on the Voyager be enough to destroy human kind? I am sure that you have received a great deal of criticism in regard to the release of the ..... record that accompanies Voyager into the depths of space. In discussing the Pioneer 10 plaque with a friend today, he felt that it would be dangerous to give ourselves away in the event that a civilization that encountered the spacecraft would be hostile and plan to eradicate us as we would wish to eradicate a virus. We have received almost nothing but praise for the inclusion of the Golden Phonograph Record on Voyager. We have also received lots of compliments on lthe contents, however, that praise rightly belongs to Carl Sagan and his colleagues who chose, assembled and got permission to use the material. There were a few detractors, even as Sagan was formulating the disk. In the Sagan, et al book, "Murmurs of Earth, the Voyager Interstellar Record", while describing some of his earlier work in sending messages from the Arecibo radar, spoke of two protests to that effort. Excerpts from that passage follow: "One was from a few scientists who worried that we hadn't corrected for the speed of Earth in space in launching the message. The other protest was a serious one, made by Sir Martin Ryle, a Nobel laureate and the Astronomer Royal of England. He wrote with great anxiety that he felt it was very hazardous to reveal our existence and location to the galaxy. Many other less knowledgeable people had the same concerns. "The fact is, for better or for worse, we have already announced our presence and location to the universe, and continue to do so every day. There is a sphere of radio transmission about thirty light years thick expanding outward at the speed of light, announcing to every star it envelops that the earth is full of people. Our television programs flood space with signals detectable at enormous distances by instruments not much greater than our own. It is a sobering thought that the first news of us may be the outcome of the Super Bowl. Whether or not Sir Martin Ryle is justified in his anxieties about revealing the location of our civilization is of course a debatable subject. Even so, it is too late to worry about it, so we might as well try to be friendly". In your opinion, what were the most important discoveries of the Voyager space probes? Voyager is probably the most scientifically productive mission ever. It was only the second mission to visit Jupiter and Saturn and the only one to visit Uranus and Neptune. Voyager 1 and 2 obtained the first detailed profiles of the atmospheres of Saturn, Uranus and Neptune and improved our understanding of the characteristics of the atmosphere of Jupiter. The Voyager spacecraft revealed the enormous amount of detail in the rings of Saturn, discovered the rings of Jupiter and provide...
