Sputnik was launched on October 4, 1957. It then began to orbit the Earth at the speed of a complete spin every 98 minutes. With its signal, the satellite allowed the USSR to send a message to the entire planet. Sputnik was very important because it initiated the space race between Soviet Union and the United States. People often do not understand the importance of it, they think it’s because it was a satellite, but Sputnik’s main threat was, of course, the missile that put him in space. It was an intercontinental ballistic missile that had been developed by the Soviet Union. It had only been tested the previous month for the first time, and for the first time in its recent history the United States felt a threatened country, “says Science and Technology historian John Krige.With the space race started, Koroliov and his engineers moved quickly. Less than a month after the Sputnik-1 launched the Sputnik-2, with the dog Laika on board. The can became the first living being in space, although he died a few hours after takeoff due to overheating.
In the years that followed, the Soviets had successes: the first man and the first woman in space, the first extravehicular exit, and the first human ingenuity to land on the Moon and then Venus. With the arrival of the Americans to the Moon in 1969, the space race initiated by the Sputnik finished.
