President Dwight D. Eisenhower established the National Aeronautics and Space Administration in 1958, partially in response to the Soviet Union's launch of the first artificial satellite. NASA grew out of the National Advisory Committee on Aeronautics, which had been researching flight technology for more than 40 years.

NASA Headquarters, in Washington, provides overall guidance and direction to the Agency. Ten field centers and a variety of installations conduct the day-to-day work of exploration and discovery.
