In tsiolkovsky's life, he was most interested in, spent the most energy and achieved the greatest success in aerospace. At an early age, questions about interstellar travel began to attract him strongly.

He recalled in 19 1 1: For a long time, like others, I thought the rocket was just a useless toy. It is difficult for me to recall exactly how I started to calculate the problem about rockets. For me, the first seeds of space flight thought were sown by jules verne's fantasy novels, and they formed a clear direction in my mind. I began to regard it as a serious activity.

Konstantin Tsiolkovsky achievements:

Frederick Zander, the father of Soviet rocket in Konstantin Tsiolkovsky, highly praised tsiolkovsky's works. 1924, the first aerospace society in the Soviet Union was established. On August 23rd, tsiolkovsky was elected as the first professor of the Military Aviation Academy. The Soviet Union built the OR- 1 liquid fuel propellant rocket in 1930 and the OR-2 rocket in 1933.

1929, tsiolkovsky put forward the idea of multi-stage rocket in his book Space Navigation. The basic formula of rocket propulsion calculation is named after him. He also believes in the idea of alien colonization put forward by the philosopher Nikolai Fedoroff, and thinks that it can make human beings exist forever.
