In the following days, Wang Bin went to the rocket manufacturing factory every day to check the manufacturing progress of the rocket. Finally, after a long wait, a huge rocket was successfully erected on the launch rack by their Tiangong technology. At the same time, the spacecraft to be launched had also been installed in the fairing on the top of the rocket, waiting for the launch day to come.


    Of course, as a private enterprise, Tiangong technology doesn''t have to be too picky about the launch time. However, in order to improve the success rate of rocket launch, it is natural to choose a sunny day for launch. Otherwise, if the weather is bad, the success rate of launch will naturally decline greatly, which will have a great risk.


    After all, apart from others, the cost of this tiangong-4 rocket is very high, not to mention the spacecraft above.


    However, fortunately, although the plum rain season in the South has come, most of this time is cloudy and rainy, but the weather will clear up one day later. According to the weather forecast, the wind on this day is also very mild, which is definitely a good day for launching rockets.


    So Wang Bin and his team immediately decided to launch the rocket in the afternoon the day after tomorrow.


    At the same time, they also began to carry out more detailed inspection of the rocket.


    Finally, the time has come to the day when the rocket is about to be launched. Because this launch is the first heavy rocket developed and manufactured by Tiangong science and Technology Institute, in addition to Wang Bin himself and the launching personnel.


    All the staff and technicians from the rocket manufacturing plant and the rocket engine laboratory came to the rocket launch site, and even the Tiangong science and technology headquarters. In addition to the necessary posts, most of the staff came to the rocket launch site to watch the rocket launch.


    Moreover, in addition to the employees on Tiangong technology''s own side and the technicians sent by the government for rocket launch and inspection, Wang Bin, the official heads of the counties, cities and even provinces where Tiangong technology is located, also came to watch the launch of Tiangong technology in person.


    Of course, in fact, this is not the first time they have come to Tiangong technology to watch the launch of rockets. After all, since the first successful launch of Tiangong technology, Tiangong technology''s rocket launch site has been well known by many people in the province.


    After all, it is impossible to hide such a big movement when launching a rocket.


    Although, in the next few launches, Wang Bin did not open to the outside world or publish it, but after the successful launch, the official released relevant news.


    However, when the rocket was launched, many people noticed the situation here, and even some people nearby took special videos.


    Seeing this situation, Wang Bin, after discussing with Tiangong technology, Qin Lao and other official space department personnel, simply stopped blocking the launch and opened the launch site of the rocket.


    Of course, for those places that want to be kept secret, Tiangong technology will not disclose to the public, such as rocket manufacturing plants and rocket engine laboratories.


    After all, rocket manufacturing factories, rocket engine laboratories and other relevant laboratories are the top priority of Tiangong technology''s rocket R & D and manufacturing. It is absolutely impossible to make it public, even for the official.


    Of course, even if they have opened the rocket launch site to the outside world, the personnel who come to watch the rocket launch cannot enter the rocket launch site within two kilometers. After all, the rocket launch is very dangerous. Even the control room where the rocket launch controller is located is nearly one kilometer away from the rocket launch pad.


    The most important thing is that the thickness of the special cement protective wall outside the rocket launch control room is as much as two or three meters, and the outside of these cement walls is also wrapped with a thick layer of sound insulation, earthquake resistance and special steel to protect the safety of internal personnel.


    It can be said that the personnel inside the control center are very safe. Even if the rocket falls directly on the control center on the way of launch, the control center can also protect the safety of internal personnel to the greatest extent.


    So at this time, neither Wang Bin nor everyone in the control room is worried about the safety of the personnel in the control room.


    Instead, Wang Bin was worried about the safety of the rocket launchers outside the control room, that is, two kilometers away from the launch pad.


    However, because these people are two kilometers away from the rocket launch pad, their safety is still very high.


    Because of such a long distance, even if the diameter of the rocket is above the launch pad, there is a problem and the explosion can not have much impact on the personnel two kilometers away.


    Moreover, even if there is a problem in midair after the launch of the rocket, the detonating device inside the rocket will detonate the fuel inside the rocket and burn it directly in the air. As for the spacecraft above the rocket, it will separate at the first time, open the parachute and then recycle it.


    It can be said that Tiangong technology has done very well in terms of safety.


    Of course, Wang Bin is still dissatisfied with this, especially with the safety of foreign trade personnel who come to watch the rocket launch. After all, since it was made public, many people will come to watch every rocket launch of Tiangong technology.


    Therefore, Wang Bin plans to build a viewing platform made of special glass at a distance of 1.5km from the rocket for those who come to watch the rocket launch. With this viewing platform made of special glass, even if the rocket has problems, the strength of special glass is enough to protect the safety of internal personnel.


    "Mr. Wang! This tiangong-4 rocket is the largest rocket manufactured since the establishment of Tiangong aerospace, and the total tonnage of this rocket has reached more than 800 tons, which has reached or exceeded the total tonnage of rockets in most countries in the world.


    If our rocket is successfully launched this time, it will definitely improve the voice of Tiangong science and technology in aerospace, and it will also greatly promote our country''s aerospace industry.


    However, although our rocket has reached the level of a truly heavy rocket in terms of gross tonnage, there is still a considerable gap in carrying capacity between it and the official rocket of the same tonnage. After all, the carrying capacity of the official rocket of the same tonnage has reached more than 20 tons, while our rocket has a maximum carrying capacity of only 15 tons. " In the control room, the person in charge of the rocket R & D and launch said.


    "Indeed, the carrying capacity of our rocket is very different from that of the official rocket of the same tonnage, with a gap of more than five tons. After all, the reason why our rocket needs to be recycled at all levels leads to the weight of each stage of our rocket exceeding that of the same type of rocket. After all, the need for recycling means that a certain number of rockets must be preserved at each stage It is precisely because these fuels occupy the carrying capacity of the rocket that the carrying capacity of the rocket is only 15 tons.


    But even so, as long as we can successfully recover the rocket, the carrying capacity I decided to pay is definitely worth it, "Wang Bin said.
