Thank you for your kind comments Bob!
Of course, discovering NEO's is extremely important to us (although just *what* we'd *do* if one was found to be heading for Earth is still a mater
of conjecture I think?). Obviously, resources that might be used for this "radar" serach of near space is imperative.However, in the case of
SETI@home, which uses the Arecibo radio telescope
, the receiver effectively "piggy backs"
whilst the telescope is surveying the sky for other projects.
Quote from here
"Like Project Phoenix, the SERENDIP receiver is based at the Arecibo Observatory, but unlike Phoenix it doesn't need to wait
for highly-prized observation time-slots. Instead, it is permanently perched above the Arecibo dish, scanning whichever part of the sky the dish
happens to be pointed at and moving through the sky with the rotation of the Earth. While this approach would not work for a targeted search, it is
well suited for an all-sky survey like SERENDIP."
As an aside - or extension to the discussion - the same reference above discusses Optical SETI - quote:
"The Planetary Society has also branched out beyond radio searches, sponsoring Optical SETI ventures that look for concentrated laser signals from
the stars. In 1998 it began supporting two targeted searches, based in Harvard and U.C. Berkeley, which look for very short light bursts coming from
candidate stars. Since the end of 2000 The Society has supplemented these projects by funding the construction of the largest dedicated Optical SETI
observatory in the world, in Harvard, Massachusetts. When completed ometime in 2002, the observatory will be used for the first all-sky Optical SETI
Still looking and listening!!
