Konstantin Tsiolkovsky

Konstantin Tsiolkovsky was a Russian scientist and pioneer of astronautics, renowned for developing the concept of rocket science and space travel. He proposed that rockets powered by liquid propellants could reach and explore space, laying the foundation for modern astronautics. His most famous idea is the "rocket equation," which describes how rockets can accelerate using expelled fuel. Tsiolkovsky's work inspired future space exploration efforts, ultimately contributing to humanity's ability to send spacecraft beyond Earth’s atmosphere. His visionary insights earned him the title of the "father of astronautics."
