Tsiolkovsky (Konstantin Tsiolkovsky)
Konstantin Tsiolkovsky was a pioneering Russian scientist who is considered one of the founding fathers of astronautics and space exploration. He developed the theoretical foundation for rocket science, establishing that rockets powered by Newton’s third law—expelling mass to produce thrust—could effectively travel to space. His key insight, known as the Tsiolkovsky rocket equation, describes how rocket velocity depends on the amount of propellant and the rocket's mass. His work laid the groundwork for modern space travel, inspiring future generations and advancing our understanding of how to reach and explore beyond Earth.
