"Hehe, sister, I want to keep it a secret. Do you know if Lao Zhao knows it?" Zhou Hao smiled, "Since Lao Zhao can't remember what this great man is, then I'll tell you. His name is Robert Huggins Goddard."

After hearing the name Zhou Hao said, Zhao Zhenzhong muttered it several times, patted his forehead and suddenly said, "I remembered it, it was him!" Then, Zhao Zhenzhong said with emotion again: "This powerful man has had a bumpy life. His historical status was many years after his death. Because of the achievements made by the Soviet Union in the field of space technology, Americans remembered that there were such a leading figure in China back then, and he reevaluated Goddard's historical achievements. Unfortunately, Goddard had passed away for more than 10 years at that time."

"Hey, Americans have such bad things. I thought this was the expertise of our people." Zhou Hao said strangely.

"What is the expertise of our Chinese people?" Zhao Zhenzhong reached out and shot Zhou Hao's forehead, "There are indeed inevitable disputes between different interest groups or individuals, but some of them are caused by the limitations of concepts and understanding at that time, and cannot be generalized. Don't forget that the United States has only more than 150 years of history from Independence Day to the present, while the history of Chinese written records alone has been more than 2,000 years. If the Americans develop for more than 2,000 years, based on the social Darwinian thought they pursue and the concept of advocating the supremacy of interests, it will be even more unbearable."

"That's all I said, Lao Zhao, don't be serious." Zhou Hao touched his forehead and sucked in a cold air, "How much do you know about this powerful man?"

Robert Hudgins Goddard, later known as the "father of Rockets" in the United States, of course, many people call him "father of modern rockets" to demonstrate his great contribution to rocket development and space exploration. Weiner von Braun, who developed the v1 and v2 rockets for Hitler and made outstanding contributions to the first artificial satellite of the United States and the first manned moon landing spacecraft, once commented on Robert Hudgins Goddard's achievements: "In the history of rocket development, Dr. Goddard is unparalleled. In the design, construction and launch of liquid rockets, he walked ahead of everyone, and it was the liquid rocket that paved the way to explore space. When Goddard completed his greatest work, we rockets and space careers only began to toddlers."

However, Goddard's Rockets research career was not smooth sailing, but full of ups and downs. His value was only re-recognized by the world after his death.

Speaking of which, Goddard is also quite legendary when he embarked on the road of Rockets' research. After reading Wells' science fiction novel "Star Wars", 16-year-old Goddard began to become interested in space and positioned his career in Rockets' research the following fall. In 1911, 29-year-old Goddard received his Ph.D. from Clark University and became a Princeton University researcher the following year.

Before that, Goddard began to conduct theoretical research on rocket dynamics in 1909. In 1911, Goddard ignited a solid fuel rocket placed in a vacuum glass container to prove that the rocket can work in a vacuum.

Because he realized the shortcomings of gunpowder rockets in a large number of research, after Goddard published a paper entitled "Methods to Achieve Great Altitudes", he focused on the research and manufacturing of liquid rockets. Unexpectedly, this paper was ridiculed by the media.

In the paper, Goddard discussed the basic mathematical principles of rocket movement and proposed the idea of ​​sending rockets to the moon. "Making a rocket weighing 598.2 kilograms can send 0.9 kilograms of magnesium to the moon. When the rocket hits the moon, the bright flash of magnesium can last for a few seconds, and you can see it on the earth with a telescope." In response to the point of view of this article, reporters from the New York Times wrote an article mocking that Goddard didn't even understand the basic physics knowledge of high school, but he fantasized about traveling to the moon all day long. Hence, he called Goddard the title of "Moon Man".

Of course, Goddard was not affected. Since 1920, he taught at Clark University during his day and continued to engage in liquid rocket research and experiments in his spare time.

During this period, due to public doubts and extreme lack of research funds, Goddard's research was difficult. This situation continued until after Goddard launched his first liquid rocket in Auburn, Massachusetts on March 26, 1926, before it improved. Although he was still facing the dilemma of shortage of research funds, at least the voices of positive comments on Goddard began to appear in the newspapers.

Later, Goddard improved the rocket's structure and conducted another liquid rocket launch test on July 29, 1929. The rocket launched this time is of milestone significance. The head of the rocket is equipped with a barometer, a thermometer and a camera, and the camera is aimed at two instruments. When the maximum altitude is reached, the parachute's catapult switch opens the camera shutter at the same time so that the temperature and pressure value of the rocket's atmosphere at the maximum altitude can be recorded. Due to the effect of the parachute, these instruments are not damaged when landing. This rocket is well deservedly called the "first sounding rocket"!

In history, due to the lack of research funds, Goddard had to engage in rocket research in his spare time, and was often in a state of intermittent. It was not until November 1929 that Goddard met Charles Linbai, a hero who flew across the Atlantic, that he received funding from the famous philanthropist Guggenheim through Linbai, and was able to concentrate on researching rockets in the following years. However, just when Goddard's rocket test achieved major results, due to the global economic depression, Guggenheim interrupted his funding in July 1932. In order to obtain funds, Linbai suggested that he report to the US military, but both the Army and the Navy refused to fund Goddard's research on liquid rockets. It was not until Daniel Florence Guggenheim Foundation gave him a grant that Goddard returned to the test site in September 1934 to continue his trial.

After World War II, Goddard once wrote letters everywhere, wanting to use his research results for the anti-fascist war. However, the military was still unwilling to spend money on liquid rockets.

In June 1944, Goddard discovered from the German V-2 missile wreckage that the German rockets were exactly the same as the rockets he made. Although it is not certain that V-2 directly used his research results, it can at least prove that Goddard could develop rockets as advanced as V-2. Looking at the works of German colleagues who were studying rockets much later than himself, but progressing rapidly due to government support, Goddard felt a lot.

By the time of Goddard's death on August 10, 1945, his Rockets career was not valued or supported by the US government throughout his life. Of the 214 patents Goddard obtained in his life, only 83 patents were obtained during his lifetime, and more than 100 other patents were recognized by the US government after Goddard's death.

What made the Americans or the world re-understand Goddard's historical status was the Soviet Union's success in intercontinental missiles, artificial satellites and manned space flight in the 1950s and 1960s. In a review of history, the US government published a report on Goddard's research on liquid rockets in 30 years in 1961, reevaluating Goddard's outstanding achievements, and earning Goddard the honorific title of "Father of American Rockets". Later, the US government named a space flight center of the Navigation Administration "Goddard Space Flight Center."

Lin Bai, who met and provided a lot of help to Goddard, thought of Goddard's multi-stage rocket blueprint 30 years ago when watching the rocket launch in 1959, and said with emotion: "I really don't know if he was dreaming at that time or if I am dreaming now."

...

After briefly explaining what he knew about Goddard, Zhao Zhenzhong asked Zhou Hao: "How much did you spend to buy liquid oxygen preparation technology and technical information for liquid rockets from him? Have you found that he received funds from other channels?"

"The Goddard doesn't understand the value of these technical materials now. I only used 30,000 US dollars to get it." Zhou Hao was a little proud, then scratched his head and said, "As for whether he has other sources of funding, I don't know. However, Lao Zhao, you don't need to worry. I have already agreed with him that if there are any research results in the future, I can still invest."

"This is not enough." Zhao Zhenzhong shook his head and said, "It is best for someone to learn from him for a few years and truly master the technical details of Goddard rocket tests. In this way, we can grasp the latest progress in rocket technology in a timely manner, lay the foundation for our future rocket career, and save us a lot of time. Are there any overseas students who conduct professional research in this area?"

Zhou Hao said affirmatively: "There is definitely no major in rocket research in this era. However, among the 39 people we came to the United States in 25 years, there are Feng Yifei and Xu Wenchang who are learning aerodynamics and aircraft manufacturing. Otherwise, let's draw one from them?"

Zhao Zhenzhong did not answer Zhou Hao's suggestion, but asked: "In addition to these two people, are there anyone else who studied aerodynamics and aircraft manufacturing among the people we went to the United States in the next few years?"

"Under our suggestions and arrangements, a certain number of overseas students choose to major in aerodynamics and aircraft manufacturing every year. After all, this professional direction is crucial to the future." Zhou Tian, ​​who was on the side, said.

Zhao Zhenzhong breathed a sigh of relief and said, "Since there are enough personnel who are studying aircraft manufacturing, then Xiaohao will mobilize and take a look. Choose one from Feng Yifei and Xu Wenchang to follow Goddard for rocket tests. From now on, select some from overseas students who have completed undergraduate majors in aerodynamics and aircraft manufacturing to study with Goddard every year."

"If this is the case, we will provide research funds for Goddard." Zhou Hao said. "In the past, due to the lack of funds, he had only four assistants besides Goddard himself. In order to save money, many of the equipment required for rocket tests were made by Goddard himself. This is why he improved the liquid oxygen manufacturing process."

"As long as our overseas students can indeed learn rocket technology, funding is not a problem," Zhou Tian promised.

"It is not only the funding for personnel and equipment, but also the need for a wider launch experimental site as the rocket continues to improve." Zhao Zhenzhong added, "In history, Goddard was a rocket test site established in New Mexico. However, if possible, we might as well choose a sparsely populated island near the shore in the northeastern United States to build a rocket test site. After all, the industry here is much more developed than that in New Mexico, and can provide timely convenience for rocket tests, and our overseas students are also here."

"Selecting a small island and using the sea as a test site is a good method." Zhou Hao nodded in agreement.

With the addition and improvement of the three, China's future rocket career wrote the opening preface like this.

Zhao Zhenzhong looked at Zhou Hao and praised with a smile: "The results you have come here this time are very good. It not only solves the liquid oxygen manufacturing problem that we have been thinking about, but also lays the foundation for our future rocket development in advance."
