How did it affect the United States?Sputnik was a milestone in the world technological development after it became the first artificial satellite of the earth. The Soviet Union was the country associated with the milestone having launched Sputnik 1 on the fourth day of October 1957. The first artificial satellite was spherical covering a diameter of 58 centimeters and weighing 83.6 kilograms. It was made from a shiny metal so that it could be easily visible, with radio antennae attached to its surface for transmission of radio signals. It went round the earth on an elliptical path within a time period of 98 minutes. On the 26thof October the power source for Sputnik 1 was exhausted and hence a month after the first satellite launch, Sputnik II was sent to the earth’s orbit. The Soviet Union milestone launches of the artificial satellite lead to new advancements in science, technology, political as well as the military and consequently intensifying the US-USSR cold war.
