The United States launched its first satellite, Explorer I, on January 31, 1958, within only a few months after the successful launch of Sputnik by the Soviets in October, 1957.  Under President Eisenhower, the National Aeronautics and Space Administration (NASA) was founded in July, 1958.  By the early 1960s, US President John F.
