Who is known as the "Father of modern rocketry" for his experiments with solid and liquid propellant?

Robert Goddard is recognized as the "Father of modern rocketry" due to his groundbreaking work in the early 20th century that laid the foundation for modern space exploration. He conducted extensive experiments with both solid and liquid propulsion systems, which were innovative for their time. His successful launch of the world's first liquid-fueled rocket in 1926 was a significant milestone, demonstrating the viability of using liquid propellants to achieve flight. Goddard's research addressed not only propulsion but also the principles of rocket stability and control, contributing significantly to the understanding and development of rocket technology in subsequent decades. His contributions are considered pivotal, as they have influenced countless advancements in the field of aerospace engineering and space travel.
