The Apollo program was the United States spaceflight effort which landed the first humans on Earth's Moon. Conceived during the Eisenhower administration and conducted by the National Aeronautics and Space Administration (NASA), Apollo began in earnest after President John F. Kennedy's 1961 address to Congress declaring his belief in a national goal of "landing a man on the Moon" by the end of the decade in a competition with the Soviet Union for supremacy in space.
