Konstantin Tsiolkovsky (1857–1935) was a self-taught scientist who became the founder of modern cosmonautics. His striving for the stars was not prevented by poverty, deafness, or isolation from the domestic scientific community. Being an eccentric and dreamer, Tsiolkovsky devoted all his strength to science. He sent his first scientific works "Theory of gases", "Mechanics of an animal organism" and "Duration of radiation of the Sun" to the capital. The learned world of that time (first of all, Ivan Sechenov and Alexander Stoletov) reacted kindly to the self-taught. He was even offered to join the Russian Physicochemical Society. Tsiolkovsky did not answer the invitation: he had nothing to pay membership dues with. Tsiolkovsky's main project at that time was an airship (the scientist decided to get away from the use of explosive hydrogen, replacing it with hot air, and the constriction system he developed allowed the "ship" to maintain constant lift at different flight altitudes), but Tsiolkovsky's interest in flying over the ground died away when he was interested in the stars. In 1903, Tsiolkovsky switched to work related to space exploration. In the article "Exploration of world spaces with jet devices" he first substantiated that a rocket could become an apparatus for successful space flights. The scientist also developed the concept of a liquid propellant rocket engine. In particular, he determined the speed required for the spacecraft to enter the Solar System ("second space speed"). Tsiolkovsky dealt with many of the practical issues of space, which later formed the basis for Soviet rocketry: he proposed options for rocket control, cooling systems, nozzle design, and fuel delivery systems.
