Following the end of World War II, a nuclear arms race evolved between the US and the Soviet Union (USSR). Since the USSR did not have bases in the western hemisphere from which to deploy bomber planes, Joseph Stalin decided to develop intercontinental ballistic missiles, which drove a missile race. The rocket technology in turn enabled both sides to develop Earth-orbiting satellites for communications, and gathering weather data and intelligence. Americans were shocked when the Soviet Union placed the first satellite into orbit in October 1957, leading to a growing fear that the US was falling into a "missile gap". A month later, the Soviets launched Sputnik 2, carrying a dog into orbit. Though the animal was not recovered alive, it was obvious their goal was human spaceflight. Unable to disclose details of military space projects, President Eisenhower ordered the creation of a civilian space agency in charge of civilian and scientific space exploration. Based on the federal research agency National Advisory Committee for Aeronautics (NACA), it was named the National Aeronautics and Space Administration (NASA). It achieved its first goal, an American satellite in space, in 1958. The next goal was to put a man there.
