Pioneer of outer space exploration

In human history, many well-known or unknown people have made unremitting efforts to study the simple reason of flying into the sky. For example, the aircraft designed by Leonardo da Vinci, although not realized at that time, proved that human beings were very eager to fly to the sky at that time.

Three scientists who have far-reaching influence on human exploration of the universe

1. robert goddard, the inventor of American rocket engine, is recognized as the father of modern rocket technology. Robert goddard was born in Massachusetts on June 5, 1982. Goddard graduated from juster Institute of Technology at the age of 24 and went to Clark University to pursue a doctorate. Both institutions are in his hometown of Massachusetts. 19 1 1 year after receiving his doctorate, he stayed in school to teach. During this period, he realized that liquid hydrogen and liquid oxygen were ideal rocket propellants, and in the following years of research, he further believed that his method would definitely send people into space.

2. 12 after robert goddard hermann oberth was born, another scientist who had a far-reaching influence on human exploration of the universe was born. Hermann oberth, known as the father of German aeronautics and astronautics, was born in Transylvania on June 25th, 1994, which belonged to the Austro-Hungarian Empire at that time and is now located in Romania.

3. In the history of human spaceflight, tsiolkovsky also had a father of rockets, Russian tsiolkovsky.

1882 mastered Newton's third law in the process of self-study. The seemingly simple principle of action and reaction suddenly opened his eyes. In his diary on March 28th, he wrote: If an opening is made at one end of a barrel filled with high-pressure gas, the gas will be ejected through this small opening, which will generate a reaction force on the barrel and make the barrel move in the opposite direction. This is an image description of the principle of rocket flight. 1883, in a paper entitled "Free Space", tsiolkovsky formally proposed to use the reaction device as the propulsion power of space travel tools. His qualitative explanation is that the theoretical basis of rocket motion is Newton's third law and the law of conservation of energy. 1896, he began to study the related problems of interstellar navigation in theory, and further clarified that only rockets can achieve this goal. 1897, he deduced the famous equation of rocket motion.
