Although, at this time, the second tiangong-4 heavy rocket of Tiangong technology has not been manufactured, it has almost been completed.


    After all, the second rocket was built a little later than the first, but not much later.


    Therefore, at this time, the second tiangong-4 heavy rocket has almost been built.


    So he asked sun Lao, "Sun Lao! I don''t know when the second rocket is going to launch. After all, at this time, whether it''s our self-developed deep space communication satellite or our second heavy rocket, it''s almost the same!"


    "Mr. Wang! According to the original plan, we are ready to launch the rocket in three days after the successful launch. However, according to the data of the meteorological department, we will have cloudy and rainy weather in the next seven or eight days. Most importantly, it will be accompanied by gusts. Therefore, it is not a good time to launch the rocket in the next few days.


    Therefore, if we want to launch the satellite developed by ourselves, we must wait at least seven or eight days, "Sun replied.


    "Seven or eight days on the second? Yes, wait until seven or eight days later, when the weather clears up, let''s start launching rockets!" Wang Bin replied.


    After that, Wang Bin said, "Hey! I don''t know if they will agree with the application report we submitted last time. After all, the plan is too huge, and the cost of money and time is too huge!"


    "Mr. Wang, do you really decide to implement the deep space star chain plan mentioned in our meeting before?


    I still reserve my opinion on this as before! "Sun said with a frown.


    Wang Bin is naturally very clear about the meaning of sun''s old saying, that is, he opposes the deep space star chain plan proposed by Wang Bin at a meeting hosted by Tiangong aerospace.


    The deep space satellite chain plan was actually put forward at the meeting when Tiangong technology had just begun to develop the first satellite, that is, it was about to complete the satellite.


    Its specific content is to establish a more advanced early warning navigation and detection network based on the official navigation system, that is, to establish an early warning detection navigation network including the solar system, so as to lay a foundation for China''s exploration and real development of space in the future.


    At the same time, it can also provide early warning for the whole mankind. After all, the earth is not absolutely safe. Let alone whether there is an alien civilization outside the earth. Only various celestial bodies inside and outside the solar system are absolutely likely to pose a fatal threat to human civilization.


    In the current situation of human civilization, it is impossible to predict the threats from deep space. It is often known only when these threats really come to the earth, for example, when various asteroids enter the earth''s atmosphere.


    Once this network is built, we can accurately locate these celestial bodies from the solar system or even from outside the solar system and calculate their trajectory. Once we find a threat to the earth, with the current technology of human civilization, we can absolutely eliminate the threat in the bud as long as we give enough time.


    Of course, this is just his idea. After all, the capital, human and material resources needed to build such a solar system navigation network are absolutely terrible.


    Even at the current profit-making speed of Tiangong technology, it is absolutely impossible for Wang Bin to complete this plan in a short time. Wang Bin''s calculation requires at least more than 50 years to preliminarily complete the construction of the solar system navigation satellite network.


    At the same time, when building this space navigation network, Tiangong technology has to invest tens of billions of funds every year, at least like this plan, which is based on Tiangong technology''s rocket recovery technology.


    If it is other aerospace companies without rocket recovery technology, the annual capital investment will be even larger, at least ten times or even more than a hundred times. Even the most powerful country in the world will feel overwhelmed by such a scale of capital investment.


    It is no wonder that sun Lao and others resolved their opposition to the plan after hearing the planarization proposed by Wang Bin.


    After all, Tiangong technology is just a private enterprise.


    However, due to Wang Bin''s persistence, in the end, they have no good way. After all, Tiangong technology, as a private enterprise, the boss''s decision cannot be changed.


    Of course, sun Lao and others also know that the plan proposed by Wang Bin before is not impossible to realize, and Wang Bin also said the specific implementation scheme of the plan at the meeting.


    According to Wang Bin''s idea, the interstellar navigation network to be built by Tiangong technology will be divided into three steps, namely, the Earth Moon system navigation early warning detection system, the solar system inner ring early warning detection navigation system and the solar system outer ring early warning navigation system.


    Of course, when the conditions are ripe and possible, Wang Bin also wants to build such a system in the outer periphery of the solar system.


    At the same time, for the benefits of this system, both sun Lao and the people from Tiangong technology and aerospace company know very well that even if the whole planned system cannot be completed, as long as part of it is completed, even if only the satellite network of the Earth Moon system is completed, it will be beneficial to the whole mankind, the whole China and their Tiangong technology, Are of extraordinary significance.


    Not to mention anything else, once this system is completed, any near Earth Asteroid threatening the earth can be found at the first time and find ways to directly understand the threat. At the same time, in the future, as long as the spacecraft of human civilization is in the Earth Moon system, it will no longer be afraid of loss.


    Most importantly, with this network, China can clearly detect the resources on the moon.


    Of course, once the system is built, its military use is absolutely huge.


    At the same time, once something happens, it is basically impossible for others to destroy this system, because the vast majority of spacecraft such as launch satellites of this system are outside the geosynchronous orbit of the earth. However, with the current technology of human civilization, it is basically a fool''s dream to attack celestial bodies outside the geosynchronous orbit.


    Of course, for such a huge plan, their Tiangong technology can''t be built alone. After all, apart from others, they can''t bypass the official only if the system wants to be built on the basis of the official current navigation satellite network.


    Moreover, this system is so huge that even if it is part of it, it can not be completed only by relying on the ability of Tiangong technology, so it certainly needs official participation and permission.


    Because of this, Wang Bin has been looking forward to the official attitude for some time.
