Obama did not, however, define the new goals tightly, leaving that up to NASA – a sensible and modest approach, but unfortunately a political mistake. It is never a good idea to replace something with vagueness.
但奥巴马也没有把新目标定得太过具体，以便给NASA留下机动空间——这堪称一个合理且恰到好处的做法，却不幸成为了政治上的败笔。要知道那些目标模糊的政策总是很容易被推翻的，而那些只关心今年就业情况和明年选票的政客和国会游说者们早就开始对这个缺乏具体细则的计划指指点点了。
