Where was the CETI created by Frank Drake and Carl Sagan in 1974 sent?
Communication with extraterrestrial intelligence Communication with extraterrestrial intelligence (a.k.a CETI) is a branch of the search for extraterrestrial intelligence that focuses on composing and deciphering interstellar messages that theoretically, could be understood by another technological civilization. This field of study once was known as "exosemiotics". The best-known CETI experiment of its kind was the 1974 Arecibo message composed by Frank Drake and Carl Sagan. There are multiple independent organizations and individuals engaged in CETI research; the generic application here of abbreviations CETI and SETI (search for extraterrestrial intelligence) should not be taken as referring to any particular organization (such as the SETI Institute).
Communications Technology Satellite The Communications Technology Satellite, also known as Hermes was an experimental high-power direct broadcast communications satellite. It was a joint effort of Canada's Department of Communications, who designed and managed it, NASA who launched it and provided a traveling wave guide, the European Space Agency or ESA who provided the 1200 watt solar panels and other devices. The three agencies shared the satellite and the data from the experiments.
