"The nuclear thermal thruster takes the Mars spacecraft out of the atmosphere, gives it an initial speed, and then starts the nuclear ion thruster in space to accelerate continuously with the minimum energy consumption. Such a nuclear thermal + Nuclear thruster will enable the Mars spacecraft to fly to Mars at the fastest speed!" Du Xingyu has a plan in mind.

    He immediately said in his mind: "invest 100000 energy points to start the simulation of nuclear ion thrusters!"

    Technology simulator: "simulation turned on."

    In front of Du Xingyu, the relevant structures required by nuclear reactors and ion thrusters appeared, and Du Xingyu began to design and combine them.

    He has overcome the difficulty of small and safe nuclear reactor last time. This time, what he needs to do is how to stably output nuclear energy into nuclear power, and design ion thrusters to meet the needs.

    "The liquid hydrogen cooling circulation system is still used... The nuclear power system is connected to the RF generator, heats the ions to one million degrees Celsius, restricts them through the magnetic field, rotates the ions at a fixed frequency and injects energy, so as to continuously increase the propulsion..."

    In the days when Du Xingyu was thinking about nuclear ion thrusters, another episode occurred in NASA.

    "The selection of academicians of the two academies has begun. Some people have reported to all research institutes of NASA, but I don''t know how many will be selected." Cao Liang said at the NASA meeting, "This year, the above attaches great importance to our space agency. I hope everyone will pay attention to it when applying for materials. It is not only a personal honor, but also the pride of the space agency if any of you can be selected!"

    The two academies are naturally the National Academy of Sciences and the National Academy of engineering, which is almost the highest honorary title of Chinese scholars.

    Because of this, it is difficult to become academicians of the two academies! Everyone is a leading figure with outstanding contributions and research achievements in the scientific community, such as Du Xingyu''s teacher Liu Yuan and his martial uncle Xiong Ming, who are academicians of the National Academy of engineering.

    Everyone is very serious. This is also an opportunity many scholars dream of!

    After the meeting, Cao Liang left Du Xingyu and said, "there are several places in the bureau this year. I''m going to declare you and prepare some materials."

    "Me?" Du Xingyu asked, "is it too early?"

    As the country''s top scientific research institutions, most of the academicians of the two academies are over 50 years old. Now the youngest academicians of the two academies are nearly 40 years old! And Du Xingyu is only in his early twenties.

    "You are very young," Cao Liang said, "but the two academies do not stipulate how old you must be to select academicians. Your scientific research contribution is absolutely enough. Anyway, report it first!"

    "OK, thank you for your leadership." Du Xingyu thanked. He knew that if he could become an academician, he would get more convenience in applying for scientific research funds! His opinions would also have more weight!

    Du Xingyu submitted the materials. In the space agency, some researchers much older than him submitted the materials.

    The members of the Management Committee of the National Academy of engineering are a group of old academicians and pillars of the country. They are now discussing the list of the Academy of engineering this year.

    The general situation, they have discussed, leaving only the most controversial name - Du Xingyu.

    "Ladies and gentlemen, what do you think of whether to select Du Xingyu as an academician of our academy?" a member asked.

    "Du Xingyu, of course he can," said an old academician, "and he is excellent in aerospace dynamics and meets the requirements of our Academy of engineering, but... He is only in his early twenties, which has no precedent."

    The National Academy of Sciences pays more attention to theoretical science, while the Academy of Engineering prefers applied science. Du Xingyu is obviously more suitable for the Academy of engineering. If he has made achievements in both fields, he is qualified to serve as an academician of both academies!

    "Our selection criteria are not based on age!" Liu Yuan said. "It can be said that Du Xingyu''s achievements in aerodynamics have surpassed me. He is enough to be elected an academician!"

    "Lao Liu, Du Xingyu is your student. He is really excellent. There is no doubt that he will become an academician in the future." an old academician said, "but there are still many candidates. Some of them have been declared for seven or eight consecutive years and have not been selected. Do you give priority to them this year?"

    "Those who can go first!" Xiong Ming said. "Since there are capable young generation, we should give him a bigger stage! I support letting Du Xingyu enter the engineering institute!"

    "I''m not against it. Du Xingyu can indeed enter the Engineering Institute, but he can''t put it next year or the next year?"

    After a long discussion, they couldn''t decide.

    At this time, someone reported a message.

    The member who got the news looked happy, stood up and announced: "everyone, just got the news, the Nobel prize selection committee announced that Du Xingyu was nominated for the Nobel Prize in physics next year because of his research in aerodynamics, and has been recognized by most members."

    "What? He was nominated for the Nobel Prize?" these old academicians were quite surprised. Some of them had been nominated for the Nobel Prize, and some of them had won the Nobel Prize.

    But Du Xingyu''s age is unmatched by anyone.

    "With Du Xingyu''s achievements in aerospace dynamics, there must be a Nobel Prize in physics next year!" Liu Yuan said in surprise. If his students can win the Nobel Prize, he will also have a bright face as a teacher.

    "Good boy, win honor for our country!" someone sighed.

    "I think Du Xingyu is absolutely qualified to join the Engineering Institute. We can''t bury talents!" said a big man of the Engineering Institute.

    "Yes!"

    The people agreed and finally decided that Du Xingyu would become the youngest academician of the Academy of engineering!

    ……

    "Congratulations, Congratulations! You will be upgraded from Dr. du to academician Du in the future!" Xu Lianqiu, from the Rocket Power Research Institute of the space agency, joked about Du Xingyu.

    "Your promotion seems to be on the hook. I haven''t graduated from graduate school, and you have all been academicians! You have also been nominated for the Nobel Prize..." with envy and admiration in Xu Lianqiu''s tone, she stared at Du Xingyu and tried to find some clues from him.

    "Average." Du Xingyu said with a smile, "as an academician, the Mars mission application should come down."

    Du Xingyu has applied to the above, hoping to change the next unmanned Mars exploration plan to manned landing, which is still under consideration.

    "Academician Du, half of your application has passed!" he Jingcheng also came over with a smile on his face.

    "He Gong, what is half? Is it difficult to go to Mars and only buy tickets, not return?" Du Xingyu joked.

    "Ha ha." he Jingcheng said with a smile, "the bureau is still worried. One is the problem of funds. Recently, space missions are too frequent, and there are some difficulties."

    "Second, the bureau is worried that the technology is not mature and the astronauts will have accidents when carrying out the Mars landing mission so quickly."

    "So it is decided that if we can successfully build a Mars spacecraft before the window period between Mars and earth, we will carry out a manned landing mission on Mars. If not, we will launch an unmanned Mars probe according to the original plan."

    "Great!" Du Xingyu affirmed, "before the window period, the Mars spacecraft will be manufactured! Now we can start designing the three-dimensional model of the spacecraft..."
