In the current depletion of the earth's resources, the development of space resources has become a viable solution. After all, the resources available in space are much richer than the Earth, only from our solar system, currently known, on the moon. There are abundant mineral resources on celestial bodies such as Mars and asteroids, and abundant hydrogen energy resources on wood-like planets.

Under this circumstance, "manned space flight" came into being. It not only helps us to break through the obstacles of the Earth's atmosphere, but also helps us overcome gravity and expand human activities from land and sea to space. It can also be used for humans to better understand the universe, develop space resources, and use the special environment of space to conduct various experiments and research.

For this reason, the development and utilization of space resources has gradually become the military commanding heights of the 21st century! The world's major countries are also vying to invest a lot of manpower and resources in this field, trying to get a "big cake" in space resources, but only the effective results so far have been China, Russia and the United States! It is worth mentioning that China, Russia and the United States are also the only three countries in the world with independent autonomous space capabilities!

As is known to all, in the early days of the founding of New China, China was in a state of ruin, and European and American countries also imposed a technical blockade on China, in an attempt to let the "Oriental Lion" sleep forever, but as Chairman Mao said, "blockade, blockade for ten years and eight years. China has it all."

On October 15, 2003, a day that was destined to be extraordinary in Chinese history, a day that Chinese sons and daughters were proud of.

xx2003年10月15日上午9点,中国自主研发的神舟五号飞船载“太空英雄”杨立伟成功发射,标志着中国载人航天技术的重大突破!作为中国第一代宇航员,杨立伟被中国人民称为“航天英雄”!

但是,你可能不知道的是,神舟五号成功发射升空后,出现了这样的意外,让杨立伟不禁感到冷汗。也就是说,在神舟五号飞船成功进入太空轨道后,他总能听到奇怪的“敲门窗”。在此之前,苏联宇航员还说,在宇宙飞船进入太空后,他们听到了类似的撞击窗户。声音。一些网友说,这可能是外星人问候我们的方式。

但科学是科学,没有“可能”的说法。自杨利伟成功进入外太空已有十多年。 “敲窗户”之谜逐渐显露出来。

原来,杨立伟听到的声音并非“敲窗”,而是由于飞船变形引起的碰撞摩擦。这种声音的主要原因是空间和地球之间的温差很大。飞船正在飞行中。在中间,随着温度的变化,会发生一定的变形。

航天器有很多部件,因此变形后不可避免会发生碰撞和摩擦,宇航员在太空中总是处于神经紧张的情绪中。很难区分听到的声音,他们错误地认为这是通过敲击外面发出的声音。
