The United States of America has no intention of finishing second in space. This effort is expensive-but it pays its way for freedom and for America.
John F. KennedyI believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth. No single space project...will be more exciting, or more impressive to mankind, or more important...and none will be so difficult or expensive to accomplish.
