This paper proposes extending NASA's Deep Space Network into a 6-station International Network. Discusses the design rationale with these characteristics: Avoids loss of communications due to natural hazards; earthquakes, etc.; provides latitude diversity to cover significant mission events wherever they occur; provides additional stations to cover events in high southern latitudes.
NASA's Search for Extraterrestrial Intelligence (SETI) project utilizes two complimentary search strategies: a sky survey and a targeted search. The SETI team at the Jet Propulsion Laboratory have primary responsibility to develop and carry out the sky survey part of the Microwave Observing Project. The paper describes progress that has been made to develop the major elements of the survey including a two-million channel wideband spectrum analyzer system that is being developed and constructed by JPL for the Deep Space Network. The new system will be a multiuser instrument that will serve as a prototype for the SETI Sky Survey processor. This system will be used to test the signal detection and observational strategies on deep-space network antennas in the near future.
