On July 29, 1958, President Dwight D. Eisenhower signed the National Aeronautics and Space Administration (NASA) into existence. Its mission: "to provide for research into the problems of flight within and outside the Earth's atmosphere, and for other purposes." NASA was created by an act of Congress, and it was a civilian entity rather than another branch of the military because Eisenhower wanted to ensure that the space agency pursued a scientific endeavor. He also didn't want to make the Soviets nervous that this was a weapons program. The ulterior motive, of course, was to one-up them at their own game.
