Document The Mix Tape of the Gods

by Timothy Ferris

Reposted from:
http://www.nytimes.com/2007/09/05/opinion/05ferris.html?th&emc=th

Thirty years ago today, the Voyager 1 space probe — a one-ton robotic craft whose long antennas make it look rather like a spider the size of a school bus — was launched from Cape Canaveral, Fla., on a mission to reconnoiter Jupiter and Saturn. To succeed, Voyager would have to survive five years in the vacuum of space, where it would encounter cosmic rays, solar flares, the hurtling rocks and sand of the asteroid belt, and Jupiter's intense radiation bands.

The probe did all that, transmitting back reams of scientific data and memorable color photos: of the sputtering red and yellow volcanoes of Jupiter's moon Io; of the shimmering blue ice that shrouds Io's fellow satellite Europa, beneath which a liquid ocean is suspected to dwell; of Saturn's myriad rings and the murky mysteries of its orange satellite, Titan, whose hazy atmosphere is thought to approximate that of the early Earth.

Having accomplished its mission, Voyager 1 might have quietly retired. Instead it remains active to this day, faithfully calling home from nearly 10 billion miles away — so great a distance that its radio signals, traveling at the speed of light, take more than 14 hours to reach Earth. From Voyager's perch, the Sun is just another star, south of Rigel in the constellation Orion, and the Sun's planets have faded to invisibility.

Like its twin, Voyager 2 — which dallied behind to examine the outer planets Uranus and Neptune and is departing the solar system on another trajectory — Voyager 1 is approaching the edge of the solar system. That limit is defined by a teardrop-shaped bubble called the heliosphere, where the solar wind (particles blown off the Sun's outer atmosphere) comes to a halt.

If all continues to go well, Voyager should pierce the heliosphere's outer skin by around 2015. It will then depart into the void of interstellar space, where it is destined to wander among the stars forever.

Mindful of this mind-boggling fact, the astronomers Carl Sagan and Frank Drake persuaded NASA to attach a gold-plated phonograph record to each of the Voyager spacecraft.

Containing photographs, natural sounds of Earth and 90 minutes of music from all over our world, the record was intended to preserve something of human culture beyond what an intelligent extraterrestrial, encountering the craft at some far-distant time and place, might infer from the spacecraft itself.

The information etched into the grooves of the Voyager record is expected to last at least one billion years. That's a long time: A billion years ago, life on Earth was first venturing forth from the seas.

Over the past three decades, the gold record has become an article of international curiosity. Spirited discussions continue about what we might do differently if we were making it today. (Having produced the record, I answer that I wouldn't change much.) At the time, though, the record almost didn't make it.

NASA officials, worried that Congress would ridicule the record as a waste of public money, had tried to play it down. Press-release photos of the spacecraft almost invariably showed the side opposite to where the record was bolted on, literally hiding it from view.

And after the record was completed, NASA rejected it on technical grounds. Late one night in a New York sound studio, when we'd finished cutting the master, I inscribed the words, "To the makers of music — all worlds, all times," in the "takeout grooves" next to the label. (The Voyager record is a metal version of the 33 1/3 vinyl records of the day, recorded at half-speed to double its data content. Etching an inscription between the takeout grooves was a trope I'd picked up from John Lennon.) A NASA quality-control officer checked the record against specifications and found that while the record's size, weight, composition and magnetic properties were all in order, its blueprints made no provision for an inscription.

So the record was rejected as a nonstandard part, and the space agency prepared to replace it with a blank disc. Sagan had to persuade the NASA administrator to sign a waiver before the record could fly.

Forty thousand years will elapse before Voyager 1, departing the realm of the Sun at a speed of 38,000 miles per hour, passes anywhere near another star. (It will drift within 1.7 light years of a dim bulb called AC+79 3888.) And 358,000 years will elapse before Voyager 2 approaches the bright star Sirius.

Out there, our concepts of velocity become provincial. The stars are moving, too, in gigantic orbits around the center of the Milky Way galaxy. Voyager, a toy boat on this dark sea, will not so much approach Sirius as watch it sail by, bobbing in its mighty wake.

Contemplation of Voyager's billion-year future among the stars may make us feel small and the span of our history seem insignificant. Yet the very existence of the two spacecraft and the gold records they carry suggests that there is something in the human spirit able to confront vast sweeps of space and time that we can only dimly comprehend.

If some recoil from the brink of space, others find it liberating. Our perspective was aptly expressed by the 18th-century science writer Bernard de Fontenelle, in his fictional dialogue "A Plurality of Worlds." "You have made the universe so large that I know not where I am, or what will become of me," complains a lovely young marquise whom Fontenelle is tutoring. "I protest it is dreadful."

"Dreadful, Madam?" Fontenelle replies. "For my part, I am very easy about it."

Timothy Ferris is the writer and producer of "Seeing in the Dark," a PBS film based on his book of the same name.

 avatarThe Voyager record faced many objections. As Sagan mentioned, one of the silliest was a point made by some dorky general that it would be advertising our presence to a potential enemy. Sagan polite as ever, enlightened him to the fact we'd been doing that for more than half a century already. I always remember the scary fact that here was a general who could possibly make decisions affecting humanity who hadn't a grasp of even basic science.

 avatarMeh. This person has it all wrong.

The real mix tape of God can be found through the singing of Choo Thomas' Holy Spirit songs.

Check it out here (the associated video is also worth a watch).

http://www.choothomas.com/resources.html

Laugh about it, if you like but there is a seriousnes to it as well.

Choo Thomas and her stageringly dumb book "Heaven is so real" is officaly endorsed by the largest church in Korea (the world?) - The Yoido Full Gospel Church with a congregation of 750,000. HISR is the literal world of Christ and is God's final word to his creation and Judgement Day is just around the corner.

In the book Cho documents her 17 trips to heaven with Christ and two trips to hell.

Scary and funny all at the same time.

Tout cet espace immense qui comprend notre Soleil et nos planètes, ne sera qu'une petite parcelle de l'univers ?

Aren't radio signals sound waves?? How can sound waves travel at the speed of light?

12. Comment #67964 by Cartomancer on September 5, 2007 at 12:00 pm

 avatarEr, no. Radio signals are radio waves - i.e. the long end of the electromagnetic spectrum (with visible light in the middle and gamma rays at the short end). Sound waves are carried by vibrations in the air and other bodies. As such radio waves do go at the speed of light, more or less. Sound waves of course do not.

Not bad for a Medieval Historian eh?! This modern science stuff is easy...

Tyler,

Even though you asked to be excused your ignorance, one or two wankers took the piss out of you for not knowing that radio is electromagnetic radiation, even though it's likely they don't know too much about radio themselves. Please excuse them, we're not all like that. We need all the support we can get from people like yourself and MIND_REBEL who dropped out of sight after being ridiculed excessively. We are giving ourselves a bad name with this kind of behaviour.

I think you made an understandable error; you probably thought that since radio is used to convey sound, that the waves themselves were sound. Radio transmission of sound uses electromagnetic radiation as a carrier which is modulated by electronically converted sound, this modulated carrier does travel at light speed.

 avatarI have to agree with Yorker. It is fun to rib people sometimes, but we can't know everything. Each of us will know a little of something. Besides atheism isn't scientism (hate that word.) You don't have to know physics or the speed of light in a vacuum before you think belief in supernatural gods is a wank. And it'd be boring as batshit if we all knew the same things and didn't have anything to teach each other.....

No, it doesn't need to be atmosphere. Sound is a mechanical pressure wave that can travel through any medium such as water, wood, steel etc.

26. Comment #68055 by BT Murtagh on September 5, 2007 at 10:24 pm

 avatarI have a little "dog tag" with a reproduction of the locating information on the disk - it shows the location of the Sun in relation to nearby pulsars, a diagram of the Solar System's major planets indicating the third, and a Mercator projection of the Earth's major land masses indicating North America (roughly in South Carolina).

This bound to be useful in case I have to hitch a ride home with different aliens than the ones who abduct me.

More seriously, I recently found a second-hand copy of "Whispers of Earth" which is about the choosing of what to put on the record. I was severely disappointed to find that the recording itself is not available for purchase or download due to asinine copyright issues.

There is a playlist, and based on that I'm guessing the message the aliens send back will be "Send more Chuck Berry."

 avatarThe Voyager spacecraft are a most wonderful achievement of the human species and one in which we should all be proud. They will outlast homo sapiens - after all, we will either become extinct or evolve into something else a billion years from now.

What a sense of perspective this brings. The farthest flung human artifact, saying: "We were here." And we decided to reach out to the cosmos, to embrace it, and not retreat into superstition. May we continue to do so. The Carl Sagans, the Timothy Ferrises and the Richard Dawkins of the world have been leading the way.

 avatarThanks to Baeoz and Damien White.

I don't want to appear as a "goody-goody" because I'm not above ridicule and aggression myself, but I only use these tactics where I feel they're warranted; never against innocent ignorance. As Rational G says, let's help those who need it, not insult them. Personally, I've learned a lot about biology and evolution here, it's one of the main reasons I keep coming back, religious discussion alone would bore me. I'm sure most people here feel they learn also, the whole experience then is a net positive result.

I think we must also be aware that in places like this, people behave in ways they wouldn't normally, probably because there's no face-to-face contact. Nothing can be done about that apart from keeping it in mind.

Little did we know then that some humans mainly made funding available to ensure that other humans could not insert an even bigger toe. What a disgraceful, small-minded state of affairs that today is even worse. The prophetic Sagan also said we came from the stars and to them we shall return. There's no question he's right but I fear it will be as unconscious atoms, not sentient human beings.

Then I noticed pewkatchoo's reference to the Children's Illustrated Encyclopedia which sounds like it's meant as an insult but I can't be certain. I am certain however, that good as it is, Dawkins UTR is not the ideal book to learn about the electromagnetic spectrum.

Containing photographs, natural sounds of Earth and 90 minutes of music from all over our world...
I read somewhere once that it includes the Rolling Stones' "Satisfaction"!! I haven't been able to confirm it anywhere else since. It would be interesting to see a comprehensive list of the music they put on the disk.

I also read once that it had a crude outline of a naked man and woman imprinted at the centre of the disk, but that may have been referring to yet another craft (although I'm pretty sure it was the Voyager, but happy to be corrected). They also had trouble convincing the NASA heavies to allow them to draw the male and female with genitals intact . (Maybe it was the same dumb-as-a-brick General who kicked up the fuss?)

Tim Ferris wrote "The Mind's Sky" which I read many years ago. Excellent book., from what I recall.

Back to the music list: I wonder what criteria they used? If I am right about "Satisfaction" -- why the hell did they pick that one?

...on further reflection, it does kind of sum up a common ailment in the human condition ;-)

 avatarOh dear, here we go again. I was not being insulting at all, just a bit of advice with a little gentle humour attached. I actually remember my childrens encyclopedia from the (harrumph) some time ago, and it described the various wavelengths very well, with pictures to boot. It was books like this that stimulated my childish urge to study electronics. I may have got the page number wrong after all this time, but there you go even pewkie is fallible.

But I did enjoy prof Dawkins explanations in Unweaving and thought that Tyler might enjoy it if he had not already read it. OK it is not ideal for a full picture of how radio waves work, but it is beautifully written.

Ok Pewk, I'll buy that and probably Tyler will as well. But I think you must admit the "childrens" part was unfortunate especially since it came after that which had went before, if you see what I mean.

Electronics hooked me as a kid also but I was torn between that and being a pilot as well. The pilot side won and I became a fast jet jockey, then I got wiser and decided I didn't want to kill people just because some politician said I should. So, back to school, got an electronics degree and did that until 1982 when I became a software engineer, went to America and did various apps and industrial control software but then ended up writing software for aircraft instrumentation! The cycle is complete, a short history of Yorker!

Did you realise your electronics dream? I hope so.
