History and Origins
The National Aeronautics and Space Administration (NASA) was established on July 29, 1958, by the National Aeronautics and Space Act. Its creation was a direct response to the Soviet Union’s launch of Sputnik 1, the first artificial satellite to orbit Earth, in 1957. This event sparked a fierce competition known as the “Space Race,” which propelled the United States to invest heavily in space exploration.
