Who made the first computations for rocket flight into space?

Konstantin Tsiolkovsky is recognized as the pioneer who made the first computations for rocket flight into space. He is often referred to as the "father of astronautics" due to his significant contributions to the theoretical foundations of space travel. In the early 20th century, Tsiolkovsky developed several important concepts, including the rocket equation, which describes how the velocity of a rocket changes as it expels propellant. His work established the framework needed for understanding how rockets could function in a vacuum and reach space, making him a critical figure in the progression of aerospace engineering.

While Dr. Goddard conducted practical experiments with liquid-fueled rockets and made significant advancements in rocket design, Tsiolkovsky's theoretical contributions laid the groundwork that enabled future developments in rocketry. Although William Hale and Konrad Kyeser von Eichstadt have made valuable contributions to aeronautics and engineering, their work did not specifically focus on the computations necessary for space travel in the manner that Tsiolkovsky's did.
