The 17th and 18th centuries saw significant advancements in the understanding of physics and engineering, laying the foundation for modern rocketry. Scientists like Isaac Newton and Robert Hooke contributed to the understanding of motion and gravity, critical concepts for rocket science.

Isaac Newton and the Laws of Motion

Isaac Newton’s formulation of the three laws of motion in the late 17th century was revolutionary. These laws described the relationship between the motion of an object and the forces acting upon it, providing a scientific basis for understanding how rockets could achieve thrust and propulsion. Newton’s work formed the cornerstone of classical mechanics and would later be applied to rocket design.

Early Theorists: Tsiolkovsky and Goddard

In the early 20th century, two pivotal figures emerged: Konstantin Tsiolkovsky in Russia and Robert H. Goddard in the United States. Tsiolkovsky is often referred to as the “father of astronautics” for his groundbreaking work on the mathematical principles of rocketry. In 1903, he published his famous rocket equation, which describes how the velocity of a rocket changes as it expels propellant.

Meanwhile, Robert Goddard conducted the first successful launch of a liquid-fueled rocket in 1926. His experiments and innovations in rocket propulsion laid the groundwork for modern rocketry and space exploration. Goddard’s work included the development of multi-stage rockets, which would later prove essential for reaching outer space.

The World Wars and Advancements in Rocketry

The two World Wars significantly accelerated advancements in rocket technology. During World War II, the German military developed the V-2 rocket, the world’s first long-range guided ballistic missile. The V-2 was powered by liquid propellant and demonstrated the potential for rocket technology in warfare and space exploration.
