在网上找到当年阿波罗登月时白宫为尼克松准备的发言稿作为一旦登月失败时的致辞。声情并茂，感人肺腑。不知道杨立伟升空的时候有没有类似的备稿，什么时候能公之于众。

即使阿姆斯特朗或者杨立伟的动机未必如下文写的那么崇高，飞入太空乃至登月确实仍是人类探索未知世界的壮举，亦如当年大航海时代英雄们的丰功伟绩。勇往直前锐意进取可能带来举步不前所不会有的失败，但后悔做过什么总比后悔没做过什么要强

Fate has ordained that the men who went to the moon to explore in peace will stay on the moon to rest in peace.

These brave men, Neil Armstrong and Edwin Aldrin, know that there is no hope for their recovery. But they also know that there is hope for mankind in their sacrifice.

These two men are laying down their lives in mankind's most noble goal: the search for truth and understanding.

They will be mourned by their families and friends; they will be mourned by their nation; they will be mourned by the people of the world; they will be mourned by a Mother Earth that dared send two of her sons into the unknown.

In their exploration, they stirred the people of the world to feel as one; in their sacrifice, they bind more tightly the brotherhood of man.

In ancient days, men looked at stars and saw their heroes in the constellations. In modern times, we do much the same, but our heroes are epic men of flesh and blood.

Others will follow, and surely find their way home. Man's search will not be denied. But these men were the first, and they will remain the foremost in our hearts.

For every human being who looks up at the moon in the nights to come will know that there is some corner of another world that is forever mankind.
