补充说明：
虽然中文叫肯尼迪航天中心，但我们参观的其实是 Kennedy Space Center Complex，是真正航天中心旁边的航天主题公园，传说是私人公司运营（官网说没花纳税人一分钱）
1962年，肯尼迪总统宣称要在60年代结束前实现人类往返月球： "We 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 are willing to accept, one we are unwilling to postpone, and one which we intend to win."
然后美国投入巨大资源在佛罗里达修建航天中心，63年肯尼迪被刺杀，为了纪念他，将这里命名为肯尼迪航天中心，并且在69年7月成功发射阿波罗11号载人飞船，第一次把人类送上月球
