  1. Question

    Do we have a formal policy for a first contact with extra-terrestrials?

    This topic has been of ongoing interest in the SETI Institute for over a decade. For an overview of current thinking, see the SETI website created for the scenario of contact via the detection of radio signals at http://www.seti.org/science/principles.html

    While this document has no legal status, it is endorsed by almost all groups engaged in serious ET searches. Similarly, there has also been some discussion about the desirability of replying to an extraterrestrial signal--if some day we detect one. A draft document on this topic can be found at http://www.seti.org/science/iaa.html
