Michael Braukus Headquarters, Washington, D.C. January 15, 1991 (Phone: 202/453-1549) Diane Stanley Ames Research Center, Mountain View, Calif. (Phone: 415/604-3934) RELEASE: 91-7 NASA SELECTS SCIENTISTS FOR SETI MICROWAVE OBSERVING PROJECT NASA has selected 9 scientists from around the country to participate as team members and interdisciplinary scientists in the Search for Extraterrestrial Intelligence (SETI) Microwave Observing Project, scheduled to begin in 1992. The SETI Microwave Observing Project consists of two elements, a Targeted Search element and a Sky Survey element. The Targeted Search will use the largest available antennas around the world and search over the frequency range from 1 to 3 gigahertz (GHz), seeking a variety of patterns in the frequency/time domain that could be indicative of an artificially generated signal. The Targeted Search will perform the most sensitive search ever conducted of nearby (less than 80 light- years distant) solar-type stars. In a complementary search strategy, the Sky Survey will use the 34-meter antennas at NASA Deep Space Network (DSN) sites in the northern and southern hemispheres to scan the entire sky over the frequency range from 1 to 10 GHz. Because of the tremendous increase in the area of the sky covered, a signal will have to be stronger to be detected by the Sky Survey. But this element could detect signals coming from the vicinity of distant sun-like stars or from directions that might be overlooked if the search were limited to nearby solar-type stars. The SETI observations will formally commence on Columbus Day 1992, with the Sky Survey system deployed at the Goldstone, Calif., DSN complex and the Targeted Search System mounted on the large radio telescope at the National Science Foundation's Arecibo Observatory in Puerto Rico. - more - - 2 - The selected investigators were chosen on the basis of a proposal to strengthen and/or enhance the SETI observations planned by NASA. The designs for the SETI-specific hardware that will be utilized to make these searches are already quite mature, but the investigators will assist in finalizing the system designs and in the development of prototype systems. The selected investigators will form the core of the project science team that will help refine the SETI search procedures, optimize the list of targeted solar-type stars, and formulate methods to extract the greatest amount of traditional radio astronomical data during the course of the scheduled SETI observations. The science team will be led by Project Scientist Dr. Jill C. Tarter at Ames Research Center, Mountain View, Calif., and by Deputy Project Scientist Dr. Sam Gulkis of the Jet Propulsion Laboratory, Pasadena, Calif. The overall Microwave Observing Project is being managed by NASA's Ames Research Center, which also bears responsibility for the Targeted Search portion of the Project. NASA's Jet Propulsion Laboratory is working with Ames and has responsibility for the Sky Survey portion of the search. The SETI Microwave Observing Project is part of NASA's Exobiology Program and is managed by the Office of Space Science and Applications, NASA Headquarters, Washington, D.C.
