Sputnik

Sputnik 1 was the first artificial Earth satellite, launched by the Soviet Union on 4 October 1957, and the event that reshaped American attitudes toward science, engineering and electronics. The satellite itself was a polished metal sphere of about 58 centimeters in diameter and roughly 84 kilograms, carrying a radio transmitter whose beeps could be picked up by amateur receivers around the world. It stayed in orbit for about three months, and its technical content was modest. Its political and economic effect was enormous, because it convinced many in the United States that the nation was behind in rockets, in education and in the electronics that guided them.

The immediate American response was institutional, and it created much of the funding structure of postwar technology. Within months the United States launched its own first satellite, Explorer 1, in January 1958, and Congress and the administration created new organizations. The Advanced Research Projects Agency (ARPA) was established in early 1958 to sponsor advanced defense research, and the National Aeronautics and Space Administration (NASA) was created in 1958 from the existing aeronautics research agency and began operating in October of that year. The National Defense Education Act of September 1958 provided federal money for science, mathematics and engineering education, including loans and fellowships. These measures drew in many young engineers who later worked in electronics.

Sputnik also illuminated the role of small electronics in the contest. A satellite or a missile guidance system must be light, because every kilogram needs fuel to lift it, and it must be reliable, because nobody can repair it in flight. These requirements favored transistors and, shortly after, integrated circuits over vacuum tubes. The US satellite Vanguard 1, launched on 17 March 1958, carried small silicon solar cells of the type announced by Bell Labs in 1954, and its solar-powered transmitter continued working for years after battery-powered signals ended, demonstrating the value of semiconductor power. Sputnik 1 itself ran on batteries, not solar cells, a detail that is sometimes confused.

The beneficiaries included the industry then taking shape in California, which was ready with talent but not yet with steady customers. Fairchild Semiconductor had been founded only weeks before the launch, and the increased national budget for missiles and space provided orders for silicon transistors, and later for integrated circuits, that began to flow in the following years. The same funding, together with the education measures, enlarged the supply of engineers. It would be a mistake to say Sputnik created Silicon Valley, because the region's roots were established earlier by Stanford, by the electronics industry, and by Shockley Semiconductor Laboratory, but it did increase the market that the region's firms could sell into.

Several misconceptions surround the event. One is that Sputnik was a technological marvel; it was a simple sphere, and the notable accomplishment was the rocket that launched it. Another is that the United States had no space program before it; in fact, American satellite projects such as Vanguard were under way, and the first Vanguard launch attempt in December 1957 failed publicly. A third is that the US response consisted only of space spending: a large portion was invested in schools, universities and basic research, and in defense research, rather than in rockets alone.

Its reputation as a turning point remains useful for understanding how technology policy works. A visible foreign achievement prompted rapid increases in public investment, much of it in electronics, and that investment lasted well beyond the immediate scare. Later episodes that were compared to Sputnik moments suggest how powerful the analogy still is.

Read Sputnik as the shock that turned a technological contest into a national priority: a small beeping sphere that led to new agencies, new schools and new orders for the light, reliable electronics that became the semiconductor industry's first large market.
