Frank Drake

Frank Drake (1930-2022) was an American radio astronomer, the founder of observational SETI, and author of the Drake equation. He represents the scientific search for extraterrestrial intelligence that ufology runs parallel to and rarely touches.

At the Green Bank observatory in 1960, Drake conducted Project Ozma, aiming a radio telescope at two nearby stars for signs of signals: the first modern SETI experiment. He later led Arecibo's message transmission (1974), co-designed the Pioneer plaques and Voyager record with Carl Sagan, and served as a leading figure of the SETI Institute.

Mostly as the counterexample: Drake maintained that while intelligent life is probably common, UFO reports provide no usable evidence of it, and SETI's institutional identity was built partly on that distinction. His 1961 Green Bank meeting produced the equation bearing his name, a framework multiplying star formation, habitability, life, intelligence, and civilization-lifetime factors to estimate communicating civilizations, which he described as a way to organize ignorance rather than compute an answer.

The equation, Ozma, and six decades of arguing that the search deserves instruments rather than anecdotes. Colleagues Jill Tarter and Seth Shostak carried the program forward; the modern technosignature field is its heir.

Ufologists have long argued SETI's radio-only assumptions are narrower than the phenomenon it dismisses; some SETI figures, in the UAP era, have engaged the data question more openly. Drake's own consistency drew little scandal.

Drake died in 2022. The equation remains the field's shared blackboard, appearing in this guide's glossary alongside the paradox it feeds.
