Looking at Du Xingyu''s excitement that she had started working, Xu Lianqiu showed an expression of "sure enough". She wanted to say that in order to celebrate Du Xingyu''s becoming an academician, she would go out for dinner or something, but before she said anything, Du Xingyu had already started working.

    "Lian Qiu, help me to call people and have a meeting in the conference room!" Du Xingyu has been preparing documents. These days, he has been developing Mars spacecraft on the simulator and has made a small profit.

    "OK!" Xu Lianqiu was not vague. He immediately informed the main members of the Mars task force and went to the conference room to discuss the Mars landing plan.

    In the conference room, Du Xingyu and others discussed the implementation plan of the Mars mission.

    "There are still six months before the window period. The most difficult thing is the manufacturing of Mars spacecraft." team member Zhang Yan said. He has cooperated with Du Xingyu in the research and development of aerospace aircraft and participated in the design of lunar spacecraft before.

    "The main design of the spacecraft can refer to the previous lunar spacecraft Taiyin," said Du Xingyu. "The only thing that needs to be improved is power and endurance! I have a preliminary plan, that is, using nuclear thermal and nuclear hybrid propulsion..."

    Du Xingyu explained his simulated scheme to the public, "nuclear ion thruster is the core part of the whole scheme. As long as the nuclear ion thruster test run is completed, I don''t think there is much problem in other aspects."

    Everyone has experience in the design of the main body of the spacecraft, including the command module, propulsion module and landing module. This time, progress is much faster than before.

    Experiments on Mars landing and Mars surface survival simulation were also handed over to a special team.

    Du Xingyu and many people in the team are already acquaintances. Everyone has been used to his ideas and ways of doing things. The Mars spacecraft project will be determined in the shortest time.

    "Mars Mars Mars spacecraft" is the name of the Mars spacecraft determined by them. Du Xingyu is the chief design engineer, he Jingcheng is the chief commander of the Mars landing mission, and others perform their respective duties.

    ……

    On the science and technology simulator, Du Xingyu is still continuing the research and development of nuclear power ion thrusters.

    At this time, he has developed the basic design structure of nuclear particle propeller, and the nuclear reactor, circulating cooling, electric energy conversion system and radiation protection device have been designed.

    Using the electric energy converted by nuclear energy, a continuous electromagnetic field can be generated in the engine to accelerate the ionized ions of the working medium.

    "Invest 100000 energy points to simulate the RF generator." in Du Xingyu''s mind, he constructed an RF generator different from the conventional ion thruster.

    Conventional ion thrusters directly use electromagnetic field to accelerate ions to obtain high specific impulse and micro thrust. However, in the nuclear ion thruster designed by Du Xingyu, the RF generator will heat ions to one million degrees Celsius, so that these ions can obtain more energy. In this way, they will also obtain higher specific impulse when they rush out of the magnetic field, That is, the unit propellant produces more impulse.

    The specific impulse of ion thruster is much better than that of conventional rocket thruster, but its thrust is unusually small. On earth, the thrust of ion thrusters is almost negligible.

    But when the ion thruster is in a vacuum with small planetary gravity and no air resistance, it will continue to accelerate the spacecraft and do things that conventional thrusters can''t do.

    In the simulator, the high-speed ion stream is ejected from the tail of the thruster, which produces ultra-high acceleration to the ion thruster. This reaction continues.

    Technology simulator: "the simulation is successful. Do you want to start crisis simulation?"

    "Open!" Du Xingyu put in energy points again and began to simulate the state of ion thrusters in various crisis situations.

    ……

    Two months later, the Huaxia Institute of atomic energy and the small nuclear fission reactor materials for nuclear ion thrusters were ready and sent to the spacecraft Research Institute by special vehicles.

    Here, all parts of the materials and parts of the nuclear ion thruster have been in place, waiting only for the addition of small nuclear fission reactors.

    In the test workshop, the staff used automatic equipment to assemble the nuclear ion thruster according to the structure diagram, and the experts of NASA waited patiently here.

    After the assembly is completed, it is the test run of nuclear ion thruster! Whether it is successful or not is directly related to whether the mission of manned landing on Mars can be carried out!

    "The nuclear reactor should be able to discharge stably. The key lies in whether the electromagnetic field and RF generator can continuously and stably control the electric ion injection!" Zhou Ziang, an old expert of the Atomic Energy Research Institute, and others analyzed before the test run.

    "Before us, no country has successfully completed this technology!" Liu Yuan said. "As long as the test run is completed today, we can break the international monopoly on ion thruster technology and move to a new height!"

    "It would be good if the test were carried out in space. It is difficult for the ground laboratory to simulate the vacuum state," Zhang Yan said with emotion.

    The specific impulse of ion thruster is large, but the thrust is small, so it is easy to be disturbed in the ground environment. But now the lunar base does not have suitable experimental equipment, so it can only be tested in the ground test workshop for the time being.

    Others are looking forward to it nervously. If this time is successful, the power and endurance of long-distance spacecraft will no longer be the restriction of mankind. They can explore further space!

    "Report, the nuclear ion thruster has been assembled, all indicators are in good condition, and the test run can be started!" the supervisor of the workshop reported.

    "Let''s start!" Du Xingyu said, and everyone entered the control center, which is full of computers and instruments, which can observe the data of nuclear ion thrusters in real time.

    "Countdown five, four, three, two, one! Start the nuclear ion thruster!" he Jingcheng shouted and pressed the start button.

    As the control rods in the nuclear reactor slowly rise, neutrons bombard the americium nucleus to produce a fission chain reaction, and powerful energy is released.

    Through an efficient electric energy conversion machine, these energy are converted into electric energy. At the same time, the circulating cooling system of liquid hydrogen maintains the temperature of the device to prevent the temperature of the nuclear reactor from getting out of control.

    A strong electromagnetic field has been generated to ionize the working medium. The hernia is ionized into a high-speed positively charged ion flow. The frequency of the RF generator is adjusted to be consistent with the rotation frequency of the ions, and the charged ions are heated to a high temperature of one million degrees Celsius in a short time.

    Countless high-speed and high-energy ion streams are ejected from the tail of the ion thruster, producing an ultra-high specific impulse in an instant, and the energy conversion efficiency is more than ten times that of the conventional rocket thruster!

    "The reaction is stable and the high-speed ion flow is stable," he Jingcheng whispered in the control center.

    Everyone didn''t speak. The short-term ion flow can''t show that the test run has been successful, sustained and stable. Only by maintaining ion propulsion for a long time can it be called success.

    As time went by, everyone''s breathing seemed to relax.

    Ten minutes later, it was still stable.

    Thirty minutes, nothing unusual.

    One hour is already the successful time point predicted by the test run theory. They all stood up and waited for the moment when the results were announced.
