With the tiangong-4 rocket, it rose faster and faster. Soon, the whole rocket disappeared into the eyes of everyone. In the sky, there was only a small point and the long fog generated by the combustion of liquid hydrogen and liquid oxygen in the rocket engine.


    At this time, on the large screen of the control center, the data of the tiangong-4 rocket is constantly updated. At the same time, on the way of the rocket flight, there are many telescopes staring at the rocket and transmitting real-time images to the large screen of the control center.


    In addition, over the base, that is, in the space above the base, many satellites are quietly observing the rocket, and most of these satellites naturally belong to the official. At the same time, several unknown satellites are quietly watching the rocket and sending the situation to some places.


    In this regard, both Wang Bin himself and the official fight were very clear, but they did not take any action. After all, it is impossible to launch rockets, especially such a large rocket of nearly 1000 tons, without being discovered.


    At this time, Wang Bin and others have completely focused on the data of this rocket, but fortunately, like the previous launch of tiangong-4 No. 1 rocket, that is, the first rocket, so far, the situation of this rocket is very good. All the data displayed are green, which means that it runs well.


    Soon, several boosters of the rocket will automatically disengage after the fuel runs out. According to the data, these boosters will land on an unmanned island in eastern China. At this time, there are military people on the island. Where are they waiting? After these boosters land, these military personnel will transport these boosters back.


    At this time, the rocket continues to fly upward. As the booster disengages, the next stage of the rocket will automatically shut down and separate after the fuel is about to run out. Like the previous booster, this stage of the rocket will also land on an island. After the rocket is put on the flight route, there is no good landing place except this island, At the same time, it is precisely because of the importance of the island. At this time, the government has also carried out certain construction on the island, which can now meet the recycling use of rockets.


    Of course, with the first stage separation of the rocket, the rocket flies upward at a faster speed after separation.


    Two minutes passed quickly, but the tiangong-4 No. 2 rocket had rushed out of the atmosphere and flew to a higher position.


    At this time, the two-stage rocket of this rocket will run out of fuel, so the two-stage rocket will automatically shut down at this time. However, after separation, the two-stage rocket did not ignite immediately, but continued to run in low orbit for nearly a week, and finally landed at the rocket launch site of Tiangong Technology,


    The satellite to be launched by this rocket is not a low orbit satellite, but a regional notification orbit satellite. Its operating altitude must reach at least 36000 km. Therefore, after flying out of the atmosphere and secondary separation, the rocket continues to fly to a higher orbit. When the rocket reaches the predetermined altitude and successfully enters the predetermined orbit.


    At this time, sun finally ordered the separation of stars and arrows. At the same time, the separated rocket also ignited again, lowered the orbit, and finally locked the orbit back to Tiangong technology.


    The whole launch process was exceptionally smooth. All the procedures were added up. Tiangong technology completed the launch of the deep space exploration and communication satellite developed by them in less than two hours.


    At this time, after completing the launch mission, the last stage rocket also entered the atmosphere again after circling the earth for a week, and flew towards Tiangong technology according to the orbit.


    Soon, the last stage of the rocket flew over Tiangong technology. Of course, there was no fuel inside this stage of the rocket at this time, so the speed of the rocket falling was not fast, only more than 100 meters per second. With the decrease of altitude, the atmospheric density increased, and its speed became slower and slower.


    When the height of this stage was only 2000 meters from the ground, the parachute on this stage was finally opened, and the speed of the rocket suddenly decreased from more than 100 meters per second to only more than ten meters per second.


    Of course, if you fall directly at this speed, it is still too fast. Even if you land successfully, it will cause very serious damage to the interior of the rocket. Therefore, when the rocket is less than 100 meters from the ground, the rocket engine finally ignites again and outputs power with about 10% power. Finally, when the rocket lands at the rocket launch site, The speed of the rocket just dropped to 0.


    It can be seen that the process of launching this rocket is smoother than all the rockets launched by Wang Bin''s Institute of Tiangong technology before.


    When the rocket landed in the middle of the Tiangong science and technology launch site accurately, the whole site burst into a tidal wave of cheers and applause. After all, what they launched this time was their own satellite, which did not help the official launch.


    At the same time, the successful launch of the satellite into orbit also marks the beginning of the deep space star chain project led by Tiangong technology. As official personnel, Qin Lao and his colleagues attach great importance to the project, and they know more about the importance of the project to the whole mankind and China than others.


    With the successful launch of the rocket, Wang Bin returned to the aircraft assembly workshop. After all, with the ability of Tiangong technology, it is impossible to manufacture the next satellite in a short time. After all, in terms of satellites, Tiangong technology has no production line at all, so technicians must carry out production and assembly manually. According to Wang Bin''s prediction, the next satellite, It will take at least a month to complete.


    As for the recovered rocket, it is impossible to launch it again immediately after recovery. These rockets can not be used again except the booster, which is a solid rocket. If they want to be used again, they must also be checked in detail. Only after it is determined that there are no potential safety hazards can they be launched again.


    And the time of this inspection will take at least half a month.


    At the same time, after the inspection, the Rockets should be reassembled. After all, even if these rockets are recycled in stages, not all parts can be reused.


    For example, the stage separator of the rocket is separated by detonator and other gunpowder explosion. After all use, the separator can not be used again.


    The world needed to assemble a rocket will take at least ten days and a half months.


    In other words, Tiangong technology will not launch the rocket until at least a month later.


    Of course, this is only for the tiangong-4 rocket.


    As for other rockets, because of the large number of rockets, they can be launched at any time. However, other rockets simply do not have the ability to launch deep space satellites, because these rockets simply do not have the ability to launch high orbit missions.
