Progress in the Search for Extraterrestrial Intelligence
Frank Drake
President, SETI Institute

ABSTRACT:
The Search for Extraterrestrial Intelligence (SETI) has made great
progress on three fronts. First, the continued exploitation of computer
technology has allowed the construction, at affordable costs, of systems
which can observe many tens of millions of radio channels
simultaneously, and which can search through the data for a variety of
possible radio signals. Secondly, observing strategies using two widely
separated telescopes, and utilizing differential doppler effects in signals
received, have made possible the quick and reliable identification and
rejection of man-made radio interference. This has allowed system
signal sensitivities to be increased as much as 100 times. This latter
advance has been possible only because of the third development,
which has been the commitment of substantial and reliable funding to
SETI by generous private donors.
BIOGRAPHY:
In 1960, Dr. Frank Drake, working at the National Radio Astronomy
Observatory in Green Bank, West Virginia, exploited then-new
technology to detect any radio signals sent by extraterrestrial intelligent
life. His Project Ozma became the first modern organized effort to
search for signs of extraterrestrial intelligence in the universe, and he
has been deeply involved with SETI (Search for ExtraTerrestrial
Intelligence) ever since. He devised the now-famous Drake Equation, a
tool by which we can estimate the number of extraterrestrial
civilizations we are likely to encounter in our galaxy. During his 20-
year tenure at Cornell University, Frank worked as director of the
world's largest radio-telescope, located at Arecibo in Puerto Rico. A
former president of the Astronomical Society of the Pacific, Frank is
currently a Research Professor of Astronomy and Astrophysics at the
University of California, Santa Cruz. Concurrently, since 1984, Dr.
Drake has been President of the SETI Institute in Mountain View, CA,
whose Project Phoenix is the most powerful SETI search in the world
today.
