SETI 2020: A Roadmap for Future SETI Observing Projects

by

Jill Tarter

 

 

Abstract


A recent series of workshops has laid out a roadmap for SETI research for the next few decades. Three different approaches were identified. 1) Continue the radio search; build an affordable array from consumer market components, expand the search in frequency, and increase the target list to 100,000 stars. This array will serve as a technology demonstration and enable the international radio astronomy community to realize an array that is a hundred times larger and capable (among other things) of searching a million stars. 2) Begin searches for very fast optical and infrared pulses from a million stars. 3) As Moore’s Law delivers increased computational capacity, build an omni-directional sky survey array capable of detecting strong, transient, radio signals from billions of stars.

SETI could succeed tomorrow, or it may be an endeavor for multiple generations. We are, after all, a very young technology in a very old galaxy. While our own leakage radiation continues to outshine the Sun at many frequencies, we remain detectable to others. When our use of the spectrum becomes more efficient, it will be time to consider deliberate transmissions and the really tough questions: Who will speak for Earth? What will they say? Maybe by then we will be old enough to find some answers.
