Evolution of Rocket – Let’s go back on a time machine Back when Sir Isaac Newton penned his third law of motion – “for every action, there is an equal and opposite reaction,” he could hardly have predicted that he was laying the groundwork for the field of rocket science. The concept that would eventually allow humans to break free from the chains of Earth’s gravity and explore the cosmos was, in essence, first described in his Philosophiæ Naturalis Principia Mathematica in 1687.
Fast forward to the 20th century, and Newton’s laws became the guiding principles for pioneers of modern rocketry, like Robert H. Goddard. His successful launch of the world’s first liquid-fueled rocket in 1926 marked a turning point in human history. This breakthrough, rooted in the same principles outlined by Newton, set the stage for the space age.
The following decades saw further remarkable developments. The German V-2, the world’s first long-range guided ballistic missile, became the progenitor of all rockets to come. Its principal designer, Wernher von Braun, would later play a crucial role in the development of the Saturn V rocket that propelled Apollo missions to the moon.
However, the story of rocket science is not just about reaching higher and going further. It’s also a tale of increasing efficiency and sustainability. The most notable shift in this regard is the move towards reusable rockets, championed by companies like SpaceX. Their Falcon 9 rocket, capable of landing back on Earth after delivering its payload to orbit, represents a significant leap forward in reducing the cost of space travel. It’s a development that brings the dream of making space travel as commonplace as air travel a little closer to reality.
We’re now standing at the cusp of a new era in rocket science. As companies and nations alike turn their eyes towards Mars and beyond, the principles laid down centuries ago by Newton continue to guide our way. However, the spirit of innovation and progress that defines this field ensures that the evolution of rocket science is far from over.
Like the famous line from Stanley Kubrick’s 2001: A Space Odyssey, we are continually venturing “Beyond the infinite”. In the context of rocket science, this means pushing the boundaries of what we believe to be possible, innovating, and discovering new ways to traverse the cosmos.
