Frank Drake, who pioneered the search for life on other planets, dies at 92

Drake, who planned the Dr. meeting at Green Bank, got his famous formula as a way to set the agenda. It consists of seven factors, which comprise all the knowledge and ambitions of human astrology. Some are quite experimental, such as the stellar birth rate in the Milky Way and the fraction of stars with habitable planets. Others are highly mysterious, such as the average age of a technological civilization—1,000 to 100 million years—only an estimate. Multiply the factors, and you get the approximate Hungarian number.

In a world where astronomers have obtained new data, old estimates for dolphins are well-placed, said Seth Shostak, an astronomer and spokesman for the SETI Institute. NASA’s Kepler planet-hunting satellite and ground-based telescopes have verified optimistic estimates of the abundance of potentially habitable Earth-sized planets, and scientists know from the Kepler mission that 300 million of them may be in the Milky Way alone. Huh.

“These people are either very lucky or in exceptional health,” Dr. Shostak about dolphins.

At the same time, scientists have discovered that life on Earth is more difficult and diverse than scientists thought, thriving in strange places like boiling holes under the ocean. “There is ample evidence for multiple paths of the origin of life,” said Dr. Drake.

After a brief stint at the Jet Propulsion Laboratory in Pasadena, California, he joined Cornell University as a professor, and later became director of the National Center for Astronomy and Ionosphere, or NAIC, whose 300 meters in Arecibo, PR. Will have a huge antenna. Be the first SETI device in the world. this planet. In this capacity Dr. Drake discovered a radiation belt around Jupiter and found that Venus’s fiery atmosphere is as thick as Earth’s oceans.

But Seti will remain his eternal love.

In 1971, NASA researched how to find extraterrestrial life, which became known as the Giant Project. His report, which called Dr. Drake’s “Intelligent Life in Space” in his master plan, required a group of 1,000 radio telescopes, each 100 meters in diameter, to look into space for another 1,000 light-years. However, its estimated $10 billion price tag made it one of Senator William Broxmeyer’s “golden feather” gifts for ruining the government’s budget. Although the project was never built, the report has become a bible for astronomers interested in extraterrestrial matters.

Jill Tarter, who read reports when she was a graduate student and devoted her life to the search for extraterrestrial intelligence, led an interview with the New York Times in 2012.
