Who discovered the space rocket?

The concept of the space rocket can be traced back to early 20th-century pioneers like Konstantin Tsiolkovsky, who is often referred to as the father of astronautics. He developed the theoretical foundations for rocketry and space travel. However, the first successful liquid-fueled rocket was launched by Robert H. Goddard in 1926, marking a significant milestone in the development of space rockets. These early innovations laid the groundwork for modern rocketry and space exploration.
