宇宙飞船进出地球大气层是非常危险的,高速运动的飞船会与空气剧烈摩擦,产生的热量会让普通的隔热材料灰飞烟灭。那么——热浪几千度,看你飞船怎么度!地球大气层忠实地履行着保护地球的责任,通过摩擦作用,试图把任何侵入的星体烧成灰烬。但忠实的大气层也同时带给我们巨大的麻烦,我们需要想尽办法避免进出大气层的飞船被大气摩擦热烧毁。
Spacecraft entering and exiting the Earth’s atmosphere is very dangerous, high-speed movement of the spacecraft will be intense friction with the air, the heat generated will make the ordinary insulation material ashes. Then - the Heat Waves Thousands of degrees to see how much your spacecraft! Earth’s atmosphere faithfully fulfill the responsibility of protecting the Earth, through friction, trying to burn any intruding stars ashes. However, the loyal atmosphere brings us tremendous trouble at the same time. We need to find ways to prevent the spacecraft entering and exiting the atmosphere from being burned by atmospheric friction.
