LETTERS TO THE EDITOR
Hat
Creek
Observatory

Editor: The following is a copy of my December 31, 2002 letter to Hat Creek District Ranger Deb Romberger regarding the Allen Telescope Array Project at the Hat Creek Observatory. Dear Ms. Romberger: Thank you for sending me a copy of
the Allen Telescope Array
(ATA) Environmental Assessment
report. A
longtime SETI colleague and I
went over the document very
carefully and we have the
following comments to make. As far
as environmental impact
issues are concerned, the
report seems very thorough and
complete. However, we are
puzzled by the total
omission of anything in the
document regarding the
question of past ethical behavior
of the SETI Institute. Information
on this issue was
presented at the August 28, 2002
meeting at Hat Creek.
We are also disturbed by the
perfunctory way in which
the National Forest Service
determined answers to some
of the questions from the
meeting and then categorized
them all as nonsignificant. There
are important concerns here,
and it involves the
honesty and scientific integrity
of people and organizations that
want to use federal
land, and I implore the
National Forest Service to get
the facts. Some of
us who had worked
on the now extinct NASA
search for extraterrestrial intelligence
(SETI) project
including a NASA civil servant
have come forward to tell
the NASA Inspector General
(IG) that there is scientific
fraud going on with this
endeavor. The
investigation concerned the
nonprofit SETI Institute
and the NASA Ames Research
Center that were responsible
for building special
purpose SETI signal processing
equipment to detect
artificial radio signals from the
nearest 1000 solar type
stars. Equipment
would then be taken to
major radio observatories around
the world to
complete the proposed search.
When Congress ended
funding for the project in 1993,
the SETI Institute (prime
contractor for NASA SETI)
became custodians of the
equipment under a longterm loan
agreement and they
still have it. We all
told the IG and gave them
extensive documentation that
there were major problems
with the equipment from the
beginning, particularly with the
Multi-Channel- Spectrum-Analyzer
(MCSA) that
NASA had invested something
like 30 million dollars in. The
equipment was not field
ready in 1992 but NASA and the
SETI Institute took the
equipment to the Arecibo Observatory
and went on to tell the
world that the greatest SETI
search was underway, and that
the equipment was working
flawlessly. It was a
total and complete fabrication.
Many senior engineers
and scientists told us after
this first deployment that the
MCSA was fundamentally flawed
and should be
discarded. Instead,
a two year effort was made
to fix the equipment and the
SETI Institute proceeded
to deploy in 1995 to the
Parkes Observatory in Australia. There
were again major problems
with the MCSA and the
scientific observations were
misrepresented. These realities
were not told to the public
or to the private donors or
mentioned in any publications. There is
no reason to believe
that anything has changed
since 1995 with any of the
subsequent deployments. Apparently
scientific integrity
does not count with this
organization, but world wide
publicity to enhance fundraising
does. During
the 5 year investigation, the IG
also determined that the
SETI Institute had
violated import/export laws,
had modified the government equipment
without permission
and in general had not
lived up to the loan agreement
with NASA. At one
point the IG took the case
to the San Jose Justice
Department but they declined
to pursue it since senior
NASA officials were aware of
the situation. The SETI
Institute has been audited
and reprimanded 3 times by
the NASA Inspector General. Is the
past history of the SETI
Institute and its supporters any
guide to what is going on
today with the proposed ATA that
is supposed to
advance SETI research in a big
way? This is
the question the National
Forest Service should
be asking. The University of
California is well aware of
SETI’s past history. Professor
Jack Welch of UC Berkeley,
the former director of the
Hat Creek Observatory was a
SETI advisor to NASA for
over 20 years, is on the
board of directors of the SETI
Institute and is married to Dr.
Jill Tarter who directs SETI
operations at the SETI Institute. Hat
Creek is a marginal site to
build a radio observatory for SETI
observations. The
president of the SETI Institute,
Dr. Frank Drake agrees
with me, as does the director
of the University of California
SETI project, Dr. Dan
Werthimer. Here are
the reasons. A site
at lower geographical latitude
is preferable for astronomical
reasons. The high
winds at Hat Creek will degrade
antenna sensitivity and may
destroy the antenna facility
as happened in 1993. Snow
will increase antenna maintenance
costs and will reduce
the life cycle of the antennas.
Nearby inhabitants and
vehicular traffic with cellular and
satellite phones will cause
radio frequency interference to SETI
observations since
they will have a direct line-of-sight
pathway into the radio
telescope. Finally,
the low east and west
horizons will allow a number
of geostationary satellites
that transmit at frequencies important
to SETI to cause
interference. A deep valley
going north/south is desirable.
Why Hat Creek then? an
organization that can
associate itself with the University
of California will appear
more viable and credible to
everyone. When the
SETI Institute says
they are constructing an equivalent
112 meter diameter radio
telescope they are misleading
the public. It is
all about antenna sensitivity
for a given amount of
antenna collecting area. When one
factors in the much
higher system temperature, the
wideband feed losses,
the lower antenna efficiency,
off axis beam losses
and phase array loses, the
antenna looks more like a 40
meter radio telescope and
would be of little value to SETI
or to traditional radio astronomy. The ATA
has never been analyzed
from end-to-end with a
computer model or described
in IEEE journals. I have
had many conservations with
antenna engineers at the
Jet Propulsion Laboratory regarding
future designs for the
NASA Deep Space Network
of antennas and the small
antenna concept does not seem
to be in their plans. Their
1994 report (Synthesis of a
Large Communication Aperture
using Small Antennas) clearly
rejects this idea as not
being cost effective. The
makeup of the Lassen National
Forest interdisciplinary team
with its predominance of
people from the University
of California is troubling
to us. How can
the organization applying
for use of federal land be
involved in the evaluation process?
It is evident that
calling ATA world class, answers
to the question of peer
review of the ATA and the
meaning of the 1993 Congressional SETI
resolution prohibiting
federal resources for this
endeavor came straight
from the University of
California/SETI Institute and were
not independently researched
by the National Forest
Service. Who says
this is a worldclass radio
telescope? Why isn’t
anybody else building one? Who
is the peer review committee?
Who picked them? Do
they have a vested interest
in the ATA? We are
all familiar with the peer
review committees from the NASA
SETI days when Dr.
Tarter was Chief Scientist and how
the oversight committees collectively
failed in their
mission to NASA. The
search for radio emissions from
extraterrestrial civilizations
is one of the most
intellectually stimulating and
potentially rewarding pursuits
open to humanity. Throughout
the four-decade history
of this enterprise, much
discussion has taken
place on how to detect interstellar
radio signals. In
actual fact, however, very
little systematic observational exploration
has been performed.
There is great need for
a radio telescope dedicated
to SETI research. We
however believe that the
present individuals and organizations
with their past record
of mismanagement and
deception are not the right
ones to move SETI forward.
They should not be
allowed to use National Forest
land. Robert
