Who Really Invented the Modern Rocket Engine?

When many individuals consider rockets, they probably envision something similar to SpaceX's Raptor engine , or they could remember The Saturn V rocket used for the Apollo 11 mission that sent astronauts to the Moon Rockets are not a common tool for most individuals to handle personally; however, this doesn’t mean they lack widespread use as their presence extends much farther back in history than one might assume. The initial military rockets emerged in China all the way back in 1045 CE through what were known as "fire arrows." These projectiles featured propulsive mechanisms powered by gunpowder which enabled them to travel greater distances compared to regular arrow launches conducted manually.

The invention of fireworks rockets can be attributed to the Chinese, and these are widely appreciated by numerous individuals who love setting them off during events like the Fourth of July celebrations or New Year’s Eve festivities. The advancements in rocketry progressed gradually over time until the 20th century brought about significant improvements with novel methods for launching larger items into the air. It wasn’t until Dr. Robert H. Goddard created and successfully launched the inaugural liquid-fuel rocket on March 16, 1926, that modern rockets using either liquid or solid fuels came into existence.

Goddard's research brought about a monumental advancement in rocketry, aiming for human travel within Earth’s upper atmosphere. However, his rockets only managed to ascend up to 9,000 feet—a height that isn’t particularly impressive now since amateur model rockets can reach over 2,500 feet—but this was groundbreaking during the early 1900s. Following Goddard, subsequent developments enabled rockets to transport both individuals and payloads beyond our planet, although these achievements came after his lifetime.

Dr. Robert H. Goddard and the Birth of the First Contemporary Rocket

Many individuals have contributed to turning rockets into modern technological marvels; however, only one person holds the title of "The Father of Space Flight." That individual is Dr. Robert H. Goddard, who pioneered the theoretical foundation necessary for powering rocket engines with liquid fuel. Achieving this required considerable effort, and upon transitioning his ideas into real-world applications, significant progress was made. In 1914, he secured patents for both liquid-fueled and solid-fueled rockets. Additionally, he was awarded a $5,000 grant from the Smithsonian Institution, which equates to approximately $80,000 in 2025 currency value.

In 1927, that amount had doubled, and in 1936, the Smithsonian released his discoveries in "Liquid Propellant Rocket Development." Goddard’s advancements provided a fresh approach to launching rockets, influencing research and technology for many years ahead. The rocket named “Nell,” which took flight in March 1926, used a blend of liquid oxygen and gasoline as propellants. This launch occurred at a farm located in Auburn, Massachusetts; the engine sat atop, with the oxidizer and fuel tanks positioned underneath.

This goes against modern rocket design practices, yet it’s insignificant since the test succeeded. Goddard launched his rocket, which ascended to a height of 41 feet within a mere 2.5-second flight duration. The rocket landed approximately 184 feet away from him in an adjacent cabbage patch. This accomplishment marked a first for Goddard and signaled the start of greater things to come. His efforts played a crucial role in shaping the development of subsequent technologies. the German V-2 rocket , the Saturn V, the rockets that launched the space shuttles into orbit, and many others.
