The Soviet program moved from this uncrewed satellite to Yuri Gagarin's first human spaceflight in April 1961. The US State Department's historical account explains the political response and the acceleration of the space race. An object passing overhead made a distant missile program tangible, and American officials faced questions about scientific leadership and defense. The history of Soviet space dogs follows those flights and the later missions that returned animals safely. The second mission carried separate life-support equipment and was not designed to bring her home.
(A year later, however, that figure had dropped to 10% as the U.S. began launching its own satellites into space.) After the launch of Sputnik, a poll conducted and published by the University of Michigan showed thunder empire slot that 26% of Americans surveyed thought that Russian sciences and engineering were superior to that of the United States. 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. Sputnik also contributed directly to a new emphasis on science and technology in American schools.
The satellite could keep moving after its batteries failed because an orbit does not require continuous engine thrust. NASA historian Roger Launius describes an orbit taking about 96 minutes. A museum display can be a replica or another example of the hardware, but cannot be the original satellite retrieved after this flight. The radios depended on batteries, with no solar panels to recharge them. The familiar beeps were not recorded speech or pictures.

Sputnik 1's polished sphere was 58 centimeters, or about 23 inches, in diameter. The first orbital flight of an artificial satellite, Sputnik 1, was launched in October 1957, by the Soviet Union. 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. It consisted of three silver-zinc batteries, developed at the All-Union Research Institute of Power Sources (VNIIT) under the leadership of Nikolai S. Lidorenko. The data were useful even after the satellite's separation from the second stage of the rocket; Sputnik's location was calculated from data on the location of the second stage, which followed Sputnik at a known distance. The observatories used a trajectory measurement system called "Tral", developed by OKB MEI (Moscow Energy Institute), by which they received and monitored data from transponders mounted on the R-7 rocket's core stage.
