flight是飞行，不是飞行器。

看到unlike考虑比较平行，主句主语是 a space station,但是unlike后面跟的是the short flights，比较对象不平行，应该改为the shuttle and spacecraft。 而后面的which从句修饰的是前面的shuttle 和spacecraft。 所以整句话的逻辑意思 不像短期飞行的shuttle能带燃料，持续运行的space station要能自己发电。但是short flight修饰有问题。

后面是space station，与其并列的应该是shuttle，不应该是short flights

比较对象不对等，Unlike后的关键字是the short flights，而比较对象是a space station。flight：飞行，不是飞行器

比较对象不平行，应为shuttle and spacecraft与orbiting space station比较。
