Europe's New ET Life Search Programme
hotsauce writes "The Guardian has a report on Europe's ambitious new programme to search for extra terrestial life. ESA has started a program called Cosmic Visions which will launch a series of satelites, starting with Gaia in 2011, and possibly culminating with the Exo-Earth Imager, a mission consisting of 10.000 3-metre mirror telescopes. The French are leading the charge with Corot in 2008."
I've heard about new algorithms that are going into effect at the Aricibo telescope that use wavelets to get much better results. Apparently a lot of old data is going to be re analyzed.
For those who didn't know.

...a mission consisting of 10.000 3-metre mirror telescopes.
This is an upgrade to previous versions of the plan that called for 8.735 3-metre mirror telescopes. Adding that 1.265 mirrors really helps I'm sure.

NPR did a story on the most efficient way to search for extra-terrestrial life, where it would be more efficient (energy/economic) to send craft out to distant solar systems rather than beam signals there. Apparantly the loss in signal strength is so severe (inverse square law) that signals get lost in the cosmic background.
10,000 satellites...

Is because we've been searching using imperial-measure radio wavelengths. Once we switch to metric wavelengths and start decoding in French, we'll finally be able to understand them.
This is about looking for planets, then analysing them to see if they have the conditions to support life (oxygen, co2, methane). SETI is about trying to recieve radio signals created by intelligent beings out there.
In short, this is looking for any sort of possible life, SETI is looking for "ET phone home".
SETI is fundamentally flawed, since even now we on Earth are broadcasting less and less out into space. We're using microwave and lasers to talk to our satellites, and everything on the ground is getting wired, or fed from satellites.
The days of gigawatt broadcasting over radio bands is winding to an end, so we only will have made "noise" for a century or so.
One could assume an intelligent race would outgrow the technology just as we have, or never use it in the first place.
SETI is like trying to find modern Native Americans by looking for smoke signals, when they communicate using the phone or internet these days.
I don't need no instructions to know how to rock!!!!
And furthermore, why can't you all speak English and have a representative democracy just like ours? Also, please get rid of any parts of your culture that are not identical to my own. Thanks, n1ywb.
It all comes back to Fermi's paradox. If there are intelligent (I prefer the term 'sophont') alien life forms out there, why haven't they contacted us?
One solution says 'because they don't want to'. I find that solution very plausible at the current juncture. Odds are that if there is, in fact, a conglomerate of alien nations out there, they've set down a network of powerful signal-dampening sattelites around our solar system (the Oort cloud would be a good hiding place), controlled by a very strong AI which filters the transmissions reaching us, so that only natural phenomena and signals of our own making ever reach us. This could even be standard procedure for worlds below a certain level of technology. This is called the 'Prime Directive' solution, after Gene Roddenberry's Prime Directive from Star Trek.
Of course, another (more Occam-friendly) solution to the paradox is "Because there aren't any"...
