Finding an otherwordly signal turns out to be different than what most sky surveys offer, or even what eventually might be required to decode a signal once found.

Physicist Enrico Fermi proposed informally a question that became to be known as Fermi's Paradox: If there is intelligent life out there, why haven't we found it yet? SETI astronomer, Seth Shostak, considers the relevant hugeness of the universe and the time it might take to colonize it--even by an very advanced civilization.

If amateur astronomers can just drag their telescopes to a dark, clear spot and set-up a night's observation, the calibration of the world's largest radio telescope is not quite so straightforward. Once the potentially confusing elements of signal detection are noted, a final calibration is to find a bounced signal sent to the moon from New Jersey, then back to Puerto Rico.

The Project Phoenix observing program is expected to finish in early 2005, when other telescope arrays will require new kinds of design choices. In the mean time, a host of valuable upgrades are in the works, to carry the computing power forward through the end of the decade.

Setting out for Jupiter and careening past Neptune, the Pioneer 10 spacecraft serves as a kind of unofficial mascot for SETI scientists. Had they intentionally set out to design a test signal for calibrating their sensitive telescopes, they probably would have come up with something just like it.
