GODDARD’S GREAT REDEMPTION

Robert H Goddard

In the early 20th century, American physicist Robert H Goddard came across the idea of liquid fuel propellant while he was conducting a series of practical experiments in rocketry.  Goddard, at least figuratively, was over the moon.

Goddard’s fascination with space flight tracked back to his college days at Worcester Polytechnic Institute. He was actually interested in achieving higher altitude but it was a daunting task to build a liquid fuel rocket than solid –propellant rockets. Despite a lack of resources and sufficient funding, Goddard was able to build a liquid-propellant rocket by 1926. This was game-changing. 

But the euphoria of Goddard’s discovery did not leave everyone in awe. 

Some thought he was a charlatan, others believed science could not have such a leap of discovery in the 1920s. Such was the disbelief in Goddard’s work that the New York Times in an editorial not just ridiculed Goddard’s intellect and integrity but, also accused him of not understanding Newton’s third law of motion. 

“Professor Goddard with his chair at Clark College and countenancing of Smithsonian Institution [from where he held the grant to continue his research independently] does not know Newton’s third law of motion,” read the editorial, “and the relationship between action and reaction, and of a need of something better than a vacuum against which to react. Of course, he only seems to lack the knowledge ladled out daily in high schools.”

In the same year, a similar campaign simultaneously sparked out another controversy when Goddard published one of his research works in Scientific American that intensified the prevailing wave of harsh criticism. This propelled other science outlets also arguing that space travel is nearly impossible. Some even claimed that rocketry can be traced back to more than 2,000 years and never had anyone been able to do the unthinkable: travel to space. 

But Goddard was a scientist and such criticism by non-scientists was mere noise to him. 

Perhaps the greatest influence and the lifelong gift of Goddard to humanity was his deep understanding of rocketry, inspiration, and celebration that space travel would be a reality in a few decades or so later. It was actually Goddard who initially outlined an uncrewed mission to the moon. Little did he realize that this work would become instrumental in American foreign and defense policy. Goddard’s legacy has arguably quietly been absorbed by engineers and scientists at NASA and the Russian space agency, Roscosmos, who worked frantically on Vostok, Gemini, and Apollo space programs. 

According to Goddard’s works, a rocket should essentially be a heat engine that can able to convert the heat energy or chemical energy of fuel into mechanical energy. The critical component in this energy conversation was the nozzle from which the jet blew onto the wheels. Goddard along with his counterpart De Laval found that the best conversation takes place when the nozzle initially narrowed and eventually gives rise in the speed of jet to the speed of sound. Using a De Laval nozzle, Goddard was succeeded to attain the real jet velocities between 7000 and 800ft/sec. Later with a specially designated compact device, he showed that rocket can work in a vacuum as well.

By then, NASA and several other space agencies were also working on the same principle of rocket propulsion but the only way they followed to learn was projecting heavy objects into the other planets of our solar system.  At that time, it was widely assumed that when rockets acquired a certain escape velocity they are still in a thin layer of earth’s atmosphere and it’s almost impossible to survive for a rocket from the heat of reentry. Goddard was ahead of them in some ways and one of his rockets with explosive payload would successfully crash into the moon.

In 1919, Goddard published his research work entitled “A method of reaching high extreme altitude”, condensation February 1920, Scientific American and Nature August 1920. The paper thoroughly explained the method of attaining high altitude around 20 miles, beyond the range for surrounding balloons and developed a theory of rocket propulsion taking into account the air resistance and gravity.

Goddard concluded with the statement that if most of the mass of the rocket consists of propellant, its superiority will increase enormously. 

Fifty years after, when NASA’s mission “Apollo 11” successfully landed on the moon with Neil Armstrong, Buzz Aldrin, and Michael Collins on July 1969, those who doubted that space travel was a possibility were left stunned. Those in scientific communities who had belligerently opposed the idea of a small capsule being able to land on the moon could not believe the images. 

But it was the New York Times who first came to realize its biggest mistake — dismissing the notion of rocket propulsion and the scientist behind it.

“Further investigation and experimentation have confirmed the findings of Isaac Newton in the 17th century and it is now definitely established that a rocket can function in a vacuum as well as in an atmosphere. The Times regrets the error.”

 Though this correction was made 24 years after Goddard’s death, history absolved him.
