Dear Colleague,
It is my pleasure to send you a copy of a document
entitled "Declaration of Principles Concerning Activities Following the Detection of
Extraterrestrial Intelligence."
The Declaration was developed over a period of several
years by the SETI Committee of the International Academy of Astronautics, with the
assistance of many experts interested in this question. In April of 1989 it was approved
by the Board of Trustees of the Academy, and also by the Board of Directors of the
International Institute of Space Law. Over the last two years it has been endorsed by the
Committee on Space Research, by Commission 51 of the International Astronomical Union, by
the members of Commission J of the Union Radio Scientifique Internationale, and by the
International Astronautical Federation.
9301-026b
The document is intended as a series of guidelines for
individuals or organizations, national or international, engaged in carrying out radio
searches for extraterrestrial intelligence. In the near future it will be sent by the
Academy to all such individuals and organizations with a request that they give
consideration to endorsing it.
In the meantime, the SETI Committee of the International
Academy of Astronautics will continue to review the principles and procedures of the
Declaration, and will assemble a special post-detection committee, as indicated in
Principle 9 of the document. The Committee is also working on a second declaration,
designed to expand the wording of Principle 8 into a process for obtaining international
agreement on questions about a reply from Earth after the detection of a signal.

Declaration of Principles Concerning Activities
Following the Detection of Extraterrestrial Intelligence -
We, the institutions and individuals participating in
the search for extraterrestrial intelligence,
Recognizing that the search for extraterrestrial
intelligence is an integral part of space exploration and is being undertaken for peaceful
purposes and for the common interest of all mankind,
Inspired by the profound significance for mankind of
detecting evidence of extraterrestrial intelligence, even though the probability of
detection may be low,
Recalling the Treaty on Principles Governing the
Activities of States in the Exploration and Use of Outer Space, Including the Moon and
Other Celestial Bodies, which commits States Parties to that Treaty "to inform the
Secretary General of the United Nations as well as the public and the international
scientific community, to the greatest extent feasible and practicable, of the, nature,
conduct, locations and results" of their space exploration activities (Article XI),
9301-026d
Recognizing that any initial detection may be incomplete
or ambiguous and thus require careful examination as well as confirmation, and that it is
essential to maintain the highest standards of scientific responsibility and credibility,
Agree to observe the following principles for
disseminating information about the detection of extraterrestrial intelligence:
1. Any individual, public or private research
institution, or governmental agency that believes it has detected a signal from or other
evidence of extraterrestrial intelligence (the discoverer) should seek to verify that the
most plausible explanation for the evidence is the existence of extraterrestrial
intelligence rather than some other natural phenomenon or anthropogenic phenomenon before
making any public announcement. If the evidence cannot be confirmed as indicating the
existence of extraterrestrial intelligence, the discoverer may disseminate the information
as appropriate to the discovery of any unknown phenomenon.
9301-026e
2. Prior to making a public announcement that evidence
of extra-terrestrial intelligence has been detected, the discoverer should promptly inform
all other observers or research organizations that are parties to this declaration, so
that those other parties may seek to confirm the discovery by independent observations at
other sites and so that a network can be established to enable continuous monitoring of
the signal or phenomenon. Parties to this declaration should not make any public
announcement of this information until it is determined whether this information is or is
not credible evidence of the existence of extraterrestrial intelligence. The discoverer
should inform his/her or its relevant national authorities.
9301-026f
3. After concluding that the discovery appears to be
credible evidence of extraterrestrial intelligence, and after informing other parties to
this declaration, the discoverer should inform observers throughout the world through the
Central Bureau for Astronomical Telegrams of the International Astronomical Union, and
should inform the Secretary General of the United Nations in accordance with Article XI of
the Treaty on Principles Governing the Activities of States in the Exploration and Use of
Outer Space, Including the Moon and Other Bodies. Because of their demonstrated interest
in and expertise concerning the question of the existence of extraterrestrial
intelligence, the discoverer should simultaneously inform the following international
institutions of the discovery and should provide them with all pertinent data and recorded
information concerning the evidence: the International Telecommunication Union, the
Committee on Space Research, of the International Council of Scientific Unions, the
International Astronautical Federation, the International Academy of Astronautics, the
International Institute of Space Law, Commission 51 of the International Astronomical
Union and Commission J of the International Radio Science Union.
9301-026g
4. A confirmed detection of extraterrestrial
intelligence should be disseminated promptly, openly, and widely through scientific
channels and public media, observing the procedures in this declaration. The discoverer
should have the privilege of making the first public announcement.
5. All data necessary for confirmation of detection
should be made available to the international scientific community through publications,
meetings, conferences, and other appropriate means.
6. The discovery should be confirmed and monitored and
any data bearing on the evidence of extraterrestrial intelligence should be recorded and
stored permanently to the greatest extent feasible and practicable, in a form that will
make it available for further analysis and interpretation. These recordings should be made
available to the international institutions listed above and to members of the scientific
community for further objective analysis and interpretation.
9301-026h
7. If the evidence of detection is in the form of
electromagnetic signals, the parties to this declaration should seek international
agreement to protect the appropriate frequencies by exercising procedures available
through the International Telecommunication Union. Immediate notice should be sent to the
Secretary General of the ITU in Geneva, who may include a request to minimize
transmissions on the relevant frequencies in the Weekly Circular. The Secretariat, in
conjunction with advice of the Union's Administrative Council, should explore the
feasibility and utility of convening an Extraordinary Administrative Radio Conference to
deal with the matter, subject to the opinions of the member Administrations of the ITU.
8. No response to a signal or other evidence of
extraterrestrial intelligence should be sent until appropriate international consultations
have taken place. The procedures for such consultations will be the subject of a separate
agreement, declaration or arrangement.
9301-026i
9. The SETI Committee of the International Academy of
Astronautics, in coordination with Commission 51 of the International Astronomical Union,
will conduct a continuing review of procedures for the detection of extraterrestrial
intelligence and the subsequent handling of the data. Should credible evidence of
extraterrestrial intelligence be discovered, an international committee of scientists and
other experts should be established to serve as a focal point for continuing analysis of
all observational evidence collected in the aftermath of the discovery, and also to
provide advice on the release of information to the public. This committee should be
constituted from representatives of each of the international institutions listed above
and such other members as the committee may deem necessary. To facilitate the convocation
of such a committee at some unknown time in the future, the SETI Committee of the
International Academy of Astronautics should initiate and maintain a current list of
willing representatives from each of the international institutions listed above, as well
as other individuals with relevant skills, and should make that list continuously
available through the Secretariat of the International Academy of Astronautics. The
International Academy of Astronautics will act as the Depository for this declaration and
will annually provide a current list of parties to all the parties to this declaration.
