Crowd-Funded Radio Beacon Will Message Aliens

Posted by samzenpus on from the is-there-anybody-out-there? dept.

astroengine writes "In the hope of uniting people around the globe in a long-duration project to send a radio 'message in a bottle' METI (Messaging Extraterrestrial Intelligence) signal, a crowd-funded project utilizing a refurbished radio telescope in California has begun its work. Lone Signal is a project initiated by scientists, businessmen and entrepreneurs to set up a continuous radio beacon from Earth. To support the operations of the Jamesburg Earth Station radio dish in Carmel Valley, Calif. (a dish built to support the Apollo 11 moon landing in 1969), a crowd-funding effort has been set up so that for a small fee, users can send images to the stars. If you're content with sending a text message, your first message is free. The radio dish's first target is Gliese 526, a red dwarf star 18 light-years from Earth, but the project will be considering other stellar targets believed to be harboring habitable worlds."

The radio signal merely lets nearby observers know we are advanced enough to communicate by radio, and interested in doing so. There's no reason to assume it will make us more likely to be invaded by hostile aliens, and some reasons to believe the opposite: a technologically advanced civilization is logically more likely to be able to resist an invasion, and therefore more risky as a target.

      There is certainly considerable merit in what you write. But allow me to present a different perspective for the sake of the argument. Consider the Fermi paradox and our observations of the universe so far. Although it is known that the universe is a very big place indeed, and it is thought that there must be many potentially habitable planets, in our very early and limited efforts we have yet to detect one apart from earth. It may be that they are rare, which would make life rare. If that turns out to be the case, any sort of signal created by a living intelligent being would be highly valuable in enabling other civilizations to locate the planet with life and a habitable environment, that is: earth. The fact that the civilization receiving the signal is intelligent says nothing about their values. Consider the diversity of civilizations on earth over the last 100 years. They have ranged from free and peace loving to extremely oppressive regimes that desired to commit genocide on their own population to extremely oppressive regimes that desired to commit genocide on other populations, and all manner of other combinations. The Soviet Union put the first human into space less than ten years after Stalin died and the horror was still fresh in the mind of Soviet citizens. There are still cultures today that practiced cannibalism within living memory. There are still some stone age cultures on earth at the same time as the US contemplates going to Mars, and has space probes at the edge of the solar system. There is no way of predicting what the value system of that alien civilization will be. The ones that could end up contacting the Earth may be the predator species that lured the highly advanced, peaceful, defenseless race to their planet and made them the slaves of the predators. The possession of neither an advanced technology level nor an advanced culture says anything about whether their culture will turn out to be one we find to be morally good and peaceful, and their society beneficial to contact. Still, it is exciting to consider, isn't it? Maybe they would turn out to be the equivalent of the mythical Star Trek era Vulcans coming in peace, as opposed to the earlier war-like Vulcan cultures. Let us hope that if we ever do make contact, it is in peace and friendship, and to our mutual benefit.

For example, something akin to the neutron bomb: kills the people, but does far less damage to the ecosystem and infrastructure.

By the time whatever rock they flung gets close enough to detect earth with any degree of accuracy in terms of aiming (and this will be on the order of hundreds of years from now), it may not even have enough time to alter its course for impact due to how little thrust an ion drive can put out (saving chemical thrusters for until the end may or may not be useful just because every bit of mass in this thing would count against its end speed, it would be a big waste to dump significant mass in the end rather than the beginning). And this is assuming that the ion drive or chemical thrusters even still work after hundreds of years of interstellar travel (the most we've done with an ion drive is 5 years continuous operation on the NEXT, and it used a measurable fraction of the xenon available to earth, that stuff is rare).

    This is at best a waste of money. I know he catches some flak for this, but Stephen Hawking has it right. There's no reason at all we should expect intelligent alien life forms to deal with us as respected equals, especially if they are considerably more advanced. At the same time, it would be too much to hope for them to ignore us. Our planet would be a treasure trove of scientific interest to them, and even practical interest in the same way rainforests are useful to biochemists or bacteria are useful to genetic engineers. The altruism argument ignores how very limited it is here on Earth. Forget intercultural conflict, how many people give/gave a shit enough about dead dolphins enough to boycott tuna? Or save the poor bonobos? Their intelligence is a lot closer to ours than ours would be to any life form advanced enough to travel the stars (unless they had some kind of taboo on both genetic and cybernetic enhancement.) Overall point being: altruism isn't a prerequisite for advanced spaceflight, but relentless pragmatism is.

    Fortunately, what with the speed of light being what it is, this shouldn't be of any immediate concern.

      Except that the star they are pointing it at is 18 light years away. So at best it will be 36 years before they'll be able to send get a signal back to us. That's assuming they detect the signal right away, and have the capability to send another message back to us. The planet that receives the signal may have intelligent life, but they may be a little behind us in terms of scientific knowledge. We've only had radio for less that 150 years, but humans have been around for 195,000 years, and the earth is 4.5 billion years old. That's a pretty small percentage of human history that radio has existed, even smaller if you're looking at the age of the planet. Who's to say we won't move past radio at some point, or that the radio spectrum won't be so polluted that we won't be able to detect such a weak signal from a far off star.

    I've actually done the math (link budget calculations) and a 30 meter radio telescope is actually large enough to reach quite a bit further than Alpha Centuari. With an adequately powerful transmitter (a minimum power output of something like 300 kW with sufficiently long pulses (>= 0.3 milliseconds) and a sufficiently narrow band signal Gliese 581, at 20.3 ly, is well within its reach. With a megawatt you could get even quite a bit further than that. At least out to 50-60 ly. Of course a lot depends on the size of the dish on the othe end. This assumes a dish on the other end of only 30-60 meters or so and a frequency up in the X band at 9-12 Ghz as well as a relatively short attenuating journey through our atmosphere by aiming at less than 45 degrees from the zenith. Since it's quite likely that there will be multi-kilometer scale dishes on the other end this should be quite conservative. Unfortunately I haven't seen any numbers on the power of their transmitter. That information as well as the transmission frequency, pulse length, and bandwidth are all key to how far their signal will reach. For short pulse lengths (microseconds) and the resulting wide bandwiths you'd need a gigawatt scale transmitter, although the average power would be quite a bit less.

Is this plan going to do directional antenna stuff to keep the signal aimed at that one star, or will it also just splatter around the universe?
