It is precisely because of this that when the spacecraft was about to be manufactured, that is, a few days ago, Wang Xu had taken their special Earth Moon business aircraft for Tiangong technology, namely phoenix-5 aerospace aircraft, to the moon. Therefore, when Wang Bin came to the command center, he saw that Wang Xu was already in the lunar spacecraft manufacturing base.


    In this regard, in fact, Wang Bin''s heart still envies Wang Xu very much. After all, in his current situation, I really don''t know when his superiors will allow him to go into space!


    According to Wang Bin''s estimation, the superior will not always restrict him. When the conditions are ripe, the superior will still allow him to go to space. This time is most likely when the construction of Pangu space city is completed.


    However, it is still a few years before the construction of Pangu class space city is completed. In other words, Wang Bin doesn''t need to go into space in recent years.


    Of course, this is just Wang Bin''s own guess. The specific thing depends on the official arrangement and the technical reliability of their Tiangong technology.


    "Report to the command center that the main body of the spacecraft has been built, the engine and flight control system have been installed, and the spacecraft now has preliminary flight capability. The" Dijiang "space research and exploration ship requests to fly for the first time." when all the take-off preparations are completed, Wang Xu immediately reported to the command center of Wang Bin.


    On the command center side, after listening to Wang Xu''s report, old Qin nodded and said, "Hello, designers, technicians and construction workers of the" Dijiang "space scientific research exploration and survey ship! I am the commander in chief of the construction of this spacecraft, and I am very clear about your efforts and sweat in designing and manufacturing this spacecraft.


    With your efforts and efforts, we Chinese civilization and human civilization can make this 10000 ton spaceship, which is essentially different from the spaceship made before our human civilization.


    Before that, spaceships made by human civilization could basically only fly near the earth''s orbit, and could only send humans to the moon at most. Moreover, the personnel and materials carried each time were very limited. Basically, there were only one or two people, even if they could only carry five or six people at most.


    Even so, every time a spaceship is launched, it will pay a huge price.


    However, this spaceship is different. This spaceship not only has a huge volume and a mass of more than 10000 tons, but also has the ability of real deep space navigation. It can be said that with this spaceship, the earth will no longer limit our steps in the future, and the whole solar system will become a paradise for our human civilization.


    So I want to thank you for your efforts. We human beings are about to enter a new era. At the same time, your name will be remembered in the history of human civilization, and our human civilization will be proud of you


    Now I order the spacecraft Dijiang to take off. Please pass and allow it to take off! "


    "Yes!" Wang Xu replied vigorously.


    After answering, Wang Xu immediately turned around and ordered the spaceship pilot who was already preparing behind him; "Attention, all personnel, board the ship!"


    With Wang Xu''s order, these people immediately entered the spacecraft Dijiang in an orderly manner and immediately drove up for the final self inspection before takeoff.


    Although the Dijiang space exploration and measurement ship is very intelligent, and most of the equipment has been intelligent, it still needs a large number of personnel to fly.


    According to the staffing, the spacecraft takes off. Even the minimum configuration requires hundreds of people to operate the spacecraft.


    Even now, most of the equipment of the spacecraft has not been installed in place, and the spacecraft is only flying from the lunar surface to the low earth orbit of the moon, but the most basic operators are still indispensable.


    "During the self-test of the spacecraft flight control system, the self-test of the flight control system is completed! Everything of the flight control system is normal!"


    "Spacecraft power system self inspection...! power system self inspection is completed, and power system is normal!"


    "Spacecraft steering system self-test in progress...! steering self-test completed! Steering system is normal!"


    "Spacecraft power system self inspection...! power system self inspection Wang Bin, power system is normal!"


    "The self inspection of the spacecraft thermonuclear controllable nuclear fusion system is in progress...! the self inspection of the thermonuclear controllable nuclear fusion system is completed! Everything of the thermonuclear controllable nuclear fusion system is normal!"


    "The spacecraft''s cold fusion system is in self-test.....! the cold fusion self-test is completed! Everything is normal!"


    "Spacecraft life support system self checking...!"


    With the start of the spacecraft''s self-test, the spacecraft''s intelligent detection system began to conduct self-test on each subsystem of the spacecraft.


    Although at this time, the spacecraft only has the most basic Aerospace capability and does not install other equipment, as a real spacecraft, there are hundreds of subsystems, large and small, and there are countless sub-control systems and sensors under each subsystem.


    Therefore, the self-test of the spacecraft is not fast, and it takes nearly two hours to complete. This is based on the most advanced supercomputing system of human civilization on the spacecraft. If there is no supercomputing system, it may not be possible to complete the self-test only by relying on ordinary supercomputing, even if it takes a few days!


    Two hours later, Wang Bin, Qin Lao and others finally gave the order to take off after the self inspection of the spacecraft was completed and ready.


    With the order, all the people on the side of the spaceship began to evacuate. A few minutes later, the door above the spaceship manufacturing workshop was finally opened slowly driven by the motor. White gas suddenly poured from the spaceship manufacturing workshop to the surface of the moon. Wang Bin and they naturally knew this, This is due to the temperature difference and pressure difference between the workshop and the lunar surface. As long as the air in the workshop is emptied, these gases will disappear.


    Sure enough, the white gas disappeared within a few minutes, and the astronauts in the spacecraft finally pressed the ignition button of the spacecraft engine in the spotlight.


    For a moment, the tail of the spacecraft began to emit hot flames. Then, the spacecraft began to rise slowly under the strong thrust of the engine. After the spacecraft flew away from the assembly workshop, the speed of the spacecraft began to increase rapidly, and the orbit began to change.


    After all, at this time, the fuel of the isotopic engine in the spacecraft is very limited, which can only be enough for the spacecraft to fly from the moon to the lunar low earth orbit. After a very amazing orbit, the missions of these isotopic engines will be completed. At that time, these engines will be unloaded. In the future, when the spacecraft navigates in space, it will completely rely on the power module of the spacecraft.


    After all, even the isotope engine consumes a lot of fuel, which can not support the spacecraft to navigate in the space for a long time. Therefore, the power module of the spacecraft uses the ion medium engine as the main power, and the controllable nuclear fusion engine as the standby engine.
