Initially, U.S. President Dwight Eisenhower was not surprised by Sputnik 1. He had been forewarned of the R-7's capabilities by information derived from U-2 spy plane overflight photos, as well as signals and telemetry intercepts. General James M. Gavin wrote in 1958 that he had predicted to the Army Scientific Advisory Panel on 12 September 1957 that the Soviets would launch a satellite within 30 days, and that on 4 October he and Wernher von Braun had agreed that a launch was imminent. The Eisenhower administration's first response was low-key and almost dismissive. Eisenhower was even pleased that the USSR, not the U.S., would be the first to test the waters of the still-uncertain legal status of orbital satellite overflights. Eisenhower had suffered the Soviet protests and shoot-downs of Project Genetrix (Moby Dick) balloons and was concerned about the probability of a U-2 being shot down. To set a precedent for "freedom of space" before the launch of America's secret WS-117L spy satellites, the U.S. had launched Project Vanguard as its own "civilian" satellite entry for the International Geophysical Year. Eisenhower greatly underestimated the reaction of the American public, who were shocked by the launch of Sputnik and by the televised failure of the Vanguard Test Vehicle 3 launch attempt. The sense of anxiety was inflamed by Democratic politicians, who portrayed the United States as woefully behind. One of the many books that suddenly appeared for the lay-audience noted seven points of "impact" upon the nation: Western leadership, Western strategy and tactics, missile production, applied research, basic research, education, and democratic culture. As public and the government became interested in space and related science and technology, the phenomenon was sometimes dubbed the "Sputnik craze".
The U.S. soon had a number of successful satellites, including Explorer 1, Project SCORE, and Courier 1B. However, public reaction to the Sputnik crisis spurred America to action in the Space Race, leading to the creation of both the Advanced Research Projects Agency (renamed the Defense Advanced Research Projects Agency, or DARPA, in 1972), and NASA (through the National Aeronautics and Space Act), as well as increased U.S. government spending on scientific research and education through the National Defense Education Act. Sputnik also contributed directly to a new emphasis on science and technology in American schools. With a sense of urgency, Congress enacted the 1958 National Defense Education Act, which provided low-interest loans for college tuition to students majoring in mathematics and science. After the launch of Sputnik, a poll conducted and published by the University of Michigan showed that 26% of Americans surveyed thought that Russian sciences and engineering were superior to that of the United States. (A year later, however, that figure had dropped to 10% as the U.S. began launching its own satellites into space.) One consequence of the Sputnik shock was the perception of a "missile gap". This became a dominant issue in the 1960 presidential campaign. The Communist Party newspaper Pravda only printed a few paragraphs about Sputnik 1 on 4 October. Sputnik also inspired a generation of engineers and scientists. Harrison Storms, the North American designer who was responsible for the X-15 rocket plane, and went on to head the effort to design the Apollo command and service module and Saturn V launch vehicle's second stage, was moved by the launch of Sputnik to think of space as being the next step for America. Astronauts Alan Shepard (who was the first American in space) and Deke Slayton later wrote of how the sight of Sputnik 1 passing overhead inspired them to their new careers. The launch of Sputnik 1 led to the resurgence of the suffix -nik in the English language. The American writer Herb Caen was inspired to coin the term "beatnik" in an article about the Beat Generation in the San Francisco Chronicle on 2 April 1958.
The flag of the Russian city of Kaluga (which, as Konstantin Tsiolkovsky's place of work and residency, is very dedicated to space and space travel) features a small Sputnik in the canton. On 3 October 2007 Google celebrated Sputnik's 50th anniversary with a Google Doodle.
=== Satellite navigation ===
The launch of Sputnik also planted the seeds for the development of modern satellite navigation. Two American physicists, William Guier and George Weiffenbach, at Johns Hopkins University's Applied Physics Laboratory (APL) decided to monitor Sputnik's radio transmissions and within hours realized that, because of the Doppler effect, they could pinpoint where the satellite was along its orbit. The Director of the APL gave them access to their UNIVAC computer to do the then heavy calculations required. Early the next year, Frank McClure, the deputy director of the APL, asked Guier and Weiffenbach to investigate the inverse problem: pinpointing the user's location, given the satellite's. At the time, the Navy was developing the submarine-launched Polaris missile, which required them to know the submarine's location. This led them and APL to develop the TRANSIT system, a forerunner of modern Global Positioning System (GPS) satellites.

=== Backups === At least two vintage duplicates of Sputnik 1 exist, built apparently as backup units. The first resides near Moscow in the corporate museum of Energia, the modern descendant of Korolev's design bureau, where it is on display by appointment only. The second is a flight-ready backup at the Cosmosphere space museum in Hutchinson, Kansas, United States, which also has an engineering model of the Sputnik 2.
