In whatever area in life one may meet the challenges of courage, whatever may be the sacrifices he faces if he follows his conscience - the loss of his friends, his fortune, his contentment, even the esteem of his fellow men - each man must decide for himself the course he will follow. The stories of past courage can define that ingredient - they can teach, they can offer hope, they can provide inspiration. But they cannot supply courage itself. For this each man must look into his own soul.
John F. KennedyWe set sail on this new sea because there is new knowledge to be gained, and new rights to be won, and they must be won and used for the progress of all people. For space science, like nuclear science and technology, has no conscience of its own. Whether it will become a force for good or ill depends on man, and only if the United States occupies a position of preeminence can we help decide whether this new ocean will be a sea of peace or a new terrifying theater of war.
