Step-by-step explanation:
In 1961, US President John F. Kennedy announced that America would put a man on the moon. This announcement came about a month after the Soviet Union's Yuri Gagarin became the first human to orbit the earth. Kennedy proposed to the US Congress that the United States should commit itself to achieving this goal before the end of the decade. This announcement led to the establishment of the National Aeronautics and Space Administration (NASA) and the subsequent Apollo program, which successfully landed the first humans on the moon in 1969.
