Where was the CETI created by Frank Drake and Carl Sagan in 1974 sent?
Arecibo message The Arecibo message is a 1974 interstellar radio message carrying basic information about humanity and Earth sent to globular star cluster M13 in the hope that extraterrestrial intelligence might receive and decipher it. The message was broadcast into space a single time via frequency modulated radio waves at a ceremony to mark the remodeling of the Arecibo radio telescope in Puerto Rico on 16 November 1974. The message was aimed at the current location of M13 some 25,000 light years away because M13 was a large and close collection of stars that was available in the sky at the time and place of the ceremony. The message consisted of 1,679 binary digits, approximately 210 bytes, transmitted at a frequency of 2,380 MHz and modulated by shifting the frequency by 10 Hz, with a power of 1,000 kW. The "ones" and "zeros" were transmitted by frequency shifting at the rate of 10 bits per second. The total broadcast was less than three minutes.
Regional Planetary Image Facility NASA Regional Planetary Image Facilities (RPIFs) are planetary image and data libraries located throughout the United States and abroad that are funded by both NASA and the host institutions. A network of these facilities was established in 1977 to maintain photographic and digital data as well as mission documentation. Each facility’s general holding contains images and maps of planets and their satellites taken by solar system exploration spacecraft. These planetary image facilities are open to the public. The facilities are primarily reference centers for browsing, studying, and selecting lunar and planetary photographic and cartographic materials. Experienced staff can assist scientists, educators, students, media, and the public in ordering materials for their own use. Since it was formally established, the network of RPIFs has expanded to nine U.S. facilities and seven in other countries. The first RPIF to be established outside of the U.S. was in England in 1980 at the University College London (UCL), and since then RPIFs have been set up in Canada, France, Germany, Israel, Italy, and Japan.
