Sputnik 1 (/ ˈ s p ʌ t n ɪ k, ˈ s p ʊ t n ɪ k /, Russian: Спутник-1, Satellite 1), sometimes referred to as simply Sputnik, was the first artificial Earth satellite. It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program .
That was the most immediate threat that Sputnik 1 posed. The United States, a land with a history of geographical security from European wars because of its distance, suddenly seemed vulnerable. A contributing factor to the Sputnik crisis was that the Soviets had not released a photograph of the satellite for five days after the launch. [7]
The launching of satellites, while still contributing to national prestige, is a significant economic activity as well, with public and private rocket systems competing for launches, using cost and reliability as selling points.

Oct. 4—66 years ago, on October 4, 1957, the Soviet Union launched the world into the space race after sending the first satellite, Sputnik 1, into orbit. Sputnik 1 weighed around 184 pounds and ...
The first orbital flight of an artificial satellite, Sputnik 1, was launched in October 1957, by the Soviet Union.In November, the second orbital flight took place. The Soviet Union launched the first animal to orbit the Earth, a dog, Laika, who died in orbit a few hours after launch.
Launch reliability was 100% and only two missiles failed to reach their targets. [48] The R-1 missile system entered into service in the Soviet Army on 28 November 1950. [49] [50] Though the R-1 was a close copy of the German A-4, it was ultimately considerably more reliable than its predecessor thanks to improvements made on the original design.
