Konstantin Tsiolkovsky

Father of Russian Rocketry and Spaceflight Theory

Konstantin Eduardovich Tsiolkovsky (1857–1935) was a Russian scientist who developed the mathematical foundations of astronautics and rocket propulsion.

Contributions

• Rocket Equation: Derived \( \Delta v = v_e \ln \frac{m_0}{m_f} \) for space travel calculations.
• Spaceflight Theory: Proposed multi-stage rockets and orbital mechanics principles.
• Astronautics Vision: Advocated space exploration and colonization of other planets.

Legacy

Tsiolkovsky is recognized as a visionary of astronautics; his equations underpin modern rocketry and space missions worldwide.

Facts

• Born in Izhevskoye, Russia.
• Self-taught engineer and mathematician.
• Wrote extensively on spaceflight.
• Inspired Soviet rocket engineers like Korolev.
