宇宙飞船和火箭有什么区别？
网友moisture提问：恭贺“神九”成功发射，可我有个问题一直没搞明白，宇宙飞船和火箭是一回事吗？有什么区别？不是一回事，区别很大。火箭是以热气流高速向后喷出，利用产生的反作用力向前运动的喷气推进装置。它自身携带燃烧剂与氧化剂，不依赖空气中的氧助燃，既可在大气中，又可在外层空间飞行。现代火箭可用作快速远距离运送工具，如作为探空、发射人造卫星、载人飞船、空间站的运载工具，以及其他飞行器的助推器等。如用于投送作战用的战斗部（弹头），便构成火箭武器。其中可以制导的称为导弹，无制导的称为火箭弹。宇宙飞船是一种运送航天员、货物到达太空并安全返回的一次性使用的航天器。它能基本保证航天员在太空短期生活并进行一定的工作。它的运行时间一般是几天到半个月。 简单说，火箭是一种运载工具，运载卫星或者宇宙飞船或者空间站一部分上天。宇宙飞船是一种航空器，可以从外太空返回地球，并可以多次使用。
