1883, he put forward the design scheme of the spacecraft in the article Free Space. 1895, the dream about the earth and the sky was published. While studying how the spacecraft flew into the sky, he also noticed the problem of the rocket and began to study the power of the spacecraft. 1896, he began to write the most important paper "exploring space with jet devices", and discussed the theoretical problems of using rocket engines in space flight, including heat conduction, navigation equipment, air friction heating and fuel. 1903 completed the paper "Using rocket instruments to study space" and put forward the famous Tsiolkovsky formula of rocket motion. This paper is of great significance in the development history of rocket science. The paper "Rocket Train" published by 1929 put forward the idea of multistage rocket for the first time, and later put forward the bold idea of establishing interstellar station. All these have made fundamental contributions to the cause of human spaceflight. To this end, he is known as "the father of rockets" and "the father of aerospace".
