1969年，尼尔，阿姆斯特朗首次登陆月球时，
不用多久我们就将经常去往太阳系内其他行星，甚至敢去往大阳系外的地方
许多人认为，
实际情况显然不是这样。
现实是大空探索极度困难而危险
会耗费漫长的时间
花费大量的金钱。
虽然大空探索拓展了我们对宇宙的理解，但它浪费政府经费，
并且对于提升我们在地球上的生活质量毫无帮助。
那么，我们为什么还要继续探索太空呢

探索是我们的天性使然。
从地球上最早期的人类生命开始，
我们对于未知事物的好奇心,就一直促使我们不断去往新的地方冒险。
我们渴望探索原始密林，攀登崇山峻岭，穿越深海大洋。
我们想要探索这世间最为遍远的边界一太空。
正如斯蒂芬，霍金曾经所说;“记得仰望星空，不要低头看脚下。
努力去认清你所看到的事物
并且思索是什么让这个宇宙存在。
天空令我们心驰神往，从世界各地的古老传说里明显看出这一点，
每次大空任务的进行，随之而来的是更深刻的理解，激励着我们沿着同一条
冒险之路继续前行。
虽然太空探索已成现实，
我们仍对宇宙的奥秘充满好奇。
