The three fathers of modern rocketry are Robert H. Goddard, Konstantin Tsiolkovsky, and Hermann Oberth. Robert H. Goddard is known for launching the world's first liquid-fueled rocket in 1926, while Tsiolkovsky, a Russian scientist, is credited with developing the theoretical foundations of rocketry and space travel. Hermann Oberth contributed significantly to the field with his work on rocket propulsion and space exploration, influencing both science and engineering. Together, their pioneering efforts laid the groundwork for modern space exploration.
