Frank Donald Drake (May 28, 1930 – September 2, 2022) was an American astrophysicist and astrobiologist.

He began his career as a radio astronomer, studying the planets of the Solar System and later pulsars. Drake expanded his interests to the search for extraterrestrial intelligence (SETI), beginning with Project Ozma in 1960, an attempt at extraterrestrial communication. He developed the Drake equation,<ref name="Drake 1961">Physics Today 14 (4), 40–46 (1961). Template:Cite journal</ref> which attempts to quantify the number of intelligent lifeforms that could potentially be discovered. Working with Carl Sagan, Drake helped to design the Pioneer plaque, the first physical message flown beyond the Solar System, and was part of the team that developed the Voyager Golden Record. Drake designed and implemented the Arecibo message in 1974, an extraterrestrial radio transmission of astronomical and biological information about Earth. He is the father of Advanced SETI.

Drake worked at the National Radio Astronomy Observatory, Jet Propulsion Laboratory, Cornell University, University of California at Santa Cruz, and the SETI Institute.

Early life and educationEdit

He enrolled at Cornell University on a Navy Reserve Officer Training Corps scholarship.<ref name="natgeo"/> Once there he began studying astronomy. His ideas about the possibility of extraterrestrial life were reinforced by a lecture from astrophysicist Otto Struve in 1951.<ref name="famous-scientists"/> After receiving a B.A. in Engineering Physics, Drake served briefly as an electronics officer on the heavy cruiser USS Albany. He then went on to graduate school at Harvard University from 1952 to 1955 where he received a M.S. and Ph.D. in Astronomy. His doctoral advisor was Cecilia Payne-Gaposchkin.<ref name=payne>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="natgeo"/>

CareerEdit

Drake began his research career as a radio astronomer, working at the National Radio Astronomy Observatory (NRAO) in Green Bank, West Virginia from 1958–63. At NRAO, he conducted research into radio emissions from the planets of the Solar System: using the radio telescope at Green Bank, Drake discovered the ionosphere and magnetosphere of Jupiter, and observed the atmosphere of Venus. He also mapped the radio emission from the Galactic Center.<ref name="famous-scientists"/><ref name="nss"/> Drake extended the capabilities of the under-construction Arecibo Observatory to allow it to be used for radio astronomy (it was originally designed purely for ionospheric physics).<ref name="nss">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

In April 1959, Drake obtained approval from the director Otto Struve of NRAO to begin Project Ozma, a search for extraterrestrial radio communications.<ref name="oxford-reference"/> Initially, they agreed to keep the project secret, fearing public ridicule. However, Drake decided to publicize his project after Giuseppe Cocconi and Philip Morrison published a paper in Nature in September 1959, entitled "Searching for Interstellar Communications".<ref name="famous-scientists"/><ref>Template:Cite journal</ref> Drake began his Project Ozma observations in 1960, using the NRAO 26-meter radio telescope, by searching for possible signals from the star systems Tau Ceti and Epsilon Eridani. No extraterrestrial signals were detected and the project was terminated in July 1960. After learning about Project Ozma, Carl Sagan (then a graduate student) contacted Drake, initiating a lifelong collaboration between them.<ref name="oxford-reference"/><ref name="famous-scientists"/>

In 1961, Drake devised the Drake equation, which attempted to estimate the number of extraterrestrial civilizations that might be detectable in the Milky Way.<ref name="Drake 1961" /><ref name="famous-scientists"/> The Drake equation has been described as the "second most-famous equation in science", after E=mc2.<ref name="seti-drake-equation">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

In 1963, Drake served as section chief of Lunar and Planetary Science at the Jet Propulsion Laboratory. He returned to Cornell in 1964, this time as a member of the faculty (academic staff), where he would spend the next two decades. He was promoted to Goldwin Smith Professor of Astronomy in 1976.<ref name="famous-scientists"/><ref name="oxford-reference">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="ucsc-obit">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Drake served as associate director of the Cornell Center for Radiophysics and Space ResearchTemplate:When, as director of the Arecibo Observatory from 1966 to 1968, and as director of the National Astronomy and Ionosphere Center (NAIC, which includes the Arecibo facility), from its establishment in 1971 to 1981.<ref name="ucsc-obit"/>

In 1972, Drake co-designed the Pioneer plaque with Carl Sagan and Linda Salzman Sagan. The plaque was the first physical message sent into space and intended to be understandable by any sufficiently technologically advanced extraterrestrial lifeforms that might intercept it.<ref name=pioneer>Template:Cite journal</ref> In 1974, Drake wrote the Arecibo message, the first interstellar message transmitted deliberately from Earth.<ref name="Arecibo">Template:Cite journal</ref> He later served as technical director, with Carl Sagan and Ann Druyan, in the development of the Voyager Golden Record, an improved version of the Pioneer plaque which also incorporated audio recordings.<ref name=ucsc-obit/><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

In 1984, Drake moved to the University of California at Santa Cruz (UCSC), becoming their Dean of Natural Science. The non-profit SETI Institute was founded the same year, with Drake as president of its board of trustees. Drake left his role as dean in 1988, but remained a professor at UCSC while also becoming director of the SETI Institute's Carl Sagan Center.<ref name="natgeo"/><ref name="seti-obit"/> Drake was President of the Astronomical Society of the Pacific from 1988 to 1990. From 1989 to 1992, he was chairman of the Board of Physics and Astronomy for the National Research Council.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> He retired from teaching in 1996 but remained emeritus professor of astronomy and astrophysics at UCSC.<ref name="uco-bio">University of California | Lick observatory www.ucolick.org retrieved 18:29 23 October 2011</ref> In 2010, Drake stepped down as director of The Carl Sagan Center but continued to serve on the SETI Institute's board of trustees.<ref name="famous-scientists"/><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

On the subject of the search for the existence of extra-terrestrial life, Drake said: "[A]s far as I know, the most fascinating, interesting thing you could find in the universe is not another kind of star or galaxy … but another kind of life."<ref>Template:Cite journal</ref>

Personal lifeEdit

Drake's hobbies included lapidary and the cultivation of orchids.<ref>Template:Cite book</ref>

He had five children, including science journalist Nadia Drake.<ref>Template:Cite news</ref><ref name="natgeo"/>

Drake died on September 2, 2022, at his home in Aptos, California, from natural causes at the age of 92.<ref name="NYT-20220905">Template:Cite news</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
