1903年,俄国科学家齐奥科夫斯基发表了火箭运动方程,揭开了人类进军太空的序幕。1957年10月4日由苏联研制的人类第一颗人造地球卫星(Sputnik)发射成功,从此,航天技术作为一项新的科学技术领域,得到了迅速发展。半个世纪以来,航天技术主要沿着三个主要方向发展。1.应用卫星运行于地球轨道,以通信广播、导航定位、对地观测和气象等业务为主的卫星及卫星星座。2.深空探测以了解太阳系的起源、组成演变,认识地球环境的形成和演变,探索地外生命及空间资源为目的。包括空间天文观测、曰地空间观测、月球探测及太阳系行星探测。3.载人航天以人类进入太空,利用人的思维和逻辑判断操作运行航天器,进行科学研究和试验。由于太空环境不具备人类生存的
In 1903, Russian scientist Zikovsky published a rocket equation of motion that opened the prelude to humanity’s entry into space. Since the launch of Sputnik, the first man-made earth satellite developed by the Soviet Union on October 4, 1957, space technology has been rapidly developed as a new area of science and technology. For half a century aerospace technology has mainly developed in three main directions. 1. Applications Satellite and satellite constellations operating in orbit of Earth orbit, with communications and broadcasting, navigation and positioning, earth observation and weather services. 2. Deep space exploration to understand the origins and evolution of the solar system, recognize the formation and evolution of the Earth’s environment, and explore extraterrestrial life and space resources. Including space astronomical observations, earth observation, lunar exploration and solar system planet exploration. 3. Manned spacecraft to human space, the use of human thinking and logic to operate the operation of spacecraft for scientific research and experimentation. As the space environment does not have human survival
