"Report, the rocket launch is ready, please give instructions!" as the scheduled time for the rocket launch is about to arrive, the official rocket experts have reported to Qin and Wang Bin. Wang Bin, a white haired old man who wanted to come to Tiangong technology, has also received it. Now only the rocket launch is ready.


    "Good! How are the groups?"


    "Report, everything is normal."


    "Radar OK!"


    "Remote control is normal!"


    "The electromagnetic wave is normal!"


    "Neutrino communication is normal!"


    “......”


    "The core module of Ziwei space station is normal!"


    After listening to various reports, old Qin looked at the time and found that there were only less than ten minutes left from the scheduled launch time! So he first looked at the old man in front of him, and the old man also nodded to him, and then Qin said; "Start the countdown!"


    "Yes!"


    Then everyone looked at the huge rocket standing on the launch tower.


    You know, this rocket is the largest one that China has made so far. At the same time, it is also the largest in terms of carrying capacity. The most important thing is that this rocket is still a recyclable rocket. Therefore, the launch cost is very low.


    Therefore, no matter the old man, Qin Lao and President Qiu, they attach great importance to this launch.


    "Please note that there are five minutes left in the countdown to the rocket launch!"


    "There are three minutes left in the rocket countdown!"


    "One minute left in the rocket countdown!"


    "30 seconds left for rocket launch 29,... 5, 4, 3, 2, 1, 0 launch!"


    As the controller pressed the launch button, the bottom of the rocket on the rocket launch pad spewed out a red flame and made a deafening sound. Even if the control room is a few kilometers away from the launch pad, the sound is very loud.


    With the flame jet at the bottom of the rocket, the tiangong-9 rocket carrying the core module of Ziwei began to steadily and slowly rise, and its speed was also slowly accelerating.


    At the same time, all the data of the rocket are being fed back to the console in real time through the communication system.


    Watching the rocket gradually disappear in the public''s view, Wang Bin and Qin Lao naturally looked at their own content on the big screen.


    At this time, according to the data displayed on the large screen, the height of the rocket has reached 15000 meters, and its flight speed has reached 15 times the speed of sound, and the speed is still increasing rapidly. After all, the height of the rocket launched this time has to reach 5000 kilometers! If there is not enough speed, it is impossible to send the core module into orbit.


    However, at this time, the fuel of the booster of the rocket has been consumed, so the booster began to separate under the control of the intelligent system.


    Soon, the tiangong-9 rocket broke out of the atmosphere and entered earth orbit space.


    However, at this time, the fuel of the first stage of the rocket has almost been consumed.


    Therefore, the first and second stages of the rocket began to separate automatically, and the first stage rocket began to adjust its attitude and prepare to land at the desert Aerospace Center in nearly two hours.


    The main body of the rocket, after the separation of the first and second stage rocket, the ignition of the second stage rocket, the first stage attitude adjustment, etc. are also operated by the intelligent program, and the successful ignition continues to fly to a higher orbit.


    At the same time, what is launched this time is the core module of the space station, and the three-stage rocket also has other uses, so it also has the design of fairing, so it is automatically abandoned at this time.


    At the same time, due to careful calculation, the fairing will return to the earth after staying in space for a period of time, and the fairing is also equipped with a large parachute, and the final landing place is also on the side of the great desert Aerospace Center.


    When the orbital height of the rocket reaches 3000 km, the fuel of the two stages of the rocket has been almost consumed, so the two and three stages of the rocket also began to separate.


    The two-stage rocket began to automatically adjust its attitude and began to push back to lower orbit and prepare for landing.


    As for the three-stage rocket, after ignition, it continued to fly towards a higher orbit, and finally sent the core module of the space station to the predetermined orbit.


    However, the three-stage rocket of Tiangong technology is not separated from the spacecraft as before, but directly connected with the core module.


    In fact, the space station of Tiangong science and technology also undertakes the function of space refueling station, so as to provide refueling and other services for other spacecraft in the future.


    The three-stage rocket will be used as the liquid hydrogen and liquid oxygen storage equipment of the space station. At the same time, the engine of the three-stage rocket is also very useful for the space station. In case of emergency, it can be used as the emergency power of the space station, It allows the space station to change its orbit and get out of danger.


    Of course, in fact, it is almost impossible to encounter any danger at such a high space station, unless it is hit by meteorites or attacked by lasers and other weapons from the ground, while ordinary anti satellite missiles basically do not have the ability to attack space vehicles at such a high altitude.


    However, for Tiangong technology and Huaxia, keeping the three-stage rocket engine is a precaution.


    "Yeah!!!"


    "Great! We succeeded!"


    "My God!"


    At the moment the rocket went into orbit, everyone in the control room stood up and cheered loudly. After all, this is a space station in orbit on earth!


    The entry of the core module into orbit this time represents human civilization. The first successful start of the construction of the orbiting space station is the space station, which is of great significance not only for China, but also for the whole human civilization. It represents that human civilization has taken another step away from truly stepping out of the earth.


    At this time, Qin and the old man also clapped their hands to celebrate the success of Tiangong technology and the successful launch of the core module of the orbiting space station.


    The applause from the whole development center could not be calmed, but Wang Bin and the technicians and employees of Tiangong technology were very clear that although they had successfully launched the core module of the medium orbit space station, the construction of the whole space station was just beginning.


    After all, the weight of the whole core module is only 40 tons. Even with the arrow body of the three-stage rocket, it is less than 80 tons, which is far from enough for the whole space station with a total design mass of thousands of tons.


    In the next period of time, they will launch more modules of the space station to build the space station and finally complete the construction of the space station. Only in this way can the purpose of the space station be revealed and serve as a bridgehead for the whole Chinese exploration of deep space!
