JFK:
We meet in an hour of change and challenge, in a decade of hope and fear, in an age of both knowledge and ignorance. The greater our knowledge increases, the greater our ignorance unfolds. The best stretches of the unknown still far outstrip our collective comprehension. We shall send to the moon a giant rocket more than 300 feet tall on an untried mission to an unknown celestial body and then return it safely to earth. But why some say the moon? Why choose this as our goal? We choose to go to the moon! We choose to go to the moon in this decade and do the other things, not because they are easy but because they are hard. Because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we¡¯re willing to accept, one we are unwilling to postpone. And therefore as we set said, we ask God¡¯s blessing on the most hazardous and dangerous and greatest adventure on which man has ever embarked.
