On the side of Tiangong technology, when the new production line began to be installed, the inspection of Tiangong technology''s second 004 rocket was finally completed. At the same time, the second deep space exploration satellite had been built and was ready to launch the rocket for the second time.


    At the same time, according to the official mission, on the second and third days after the launch, Wang Bin and their Tiangong technology will launch a rocket respectively to send the official satellite into space.


    In other words, in the next three days, Wang Bin''s Tiangong technology will launch three rockets and send seven satellites into space. Among them, except Tiangong technology''s own one, the remaining six are official.


    The six satellites will also be launched by two rockets in the way of one arrow and multiple stars.


    Wang Bin and the rocket launching Department of Tiangong science and technology also attach great importance to this. After all, whether launching rockets for several consecutive days or multiple satellites with one arrow is a big challenge for Tiangong science and technology. After all, in the past, the rockets launched by Tiangong science and technology need to be at least every other week, but this is a continuous launch. Therefore, before launch, Everything must be prepared.


    The difficulty of multiple stars with one arrow is higher than the previous launch difficulty.


    However, whether it is a continuous launch or multiple satellites, it is a great challenge for Tiangong technology. It is within Tiangong technology. It does not choose to retreat in spite of difficulties, but is full of confidence.


    At the same time, the official also knows that the launch is very difficult for Tiangong technology. Therefore, in order to improve Tiangong technology''s confidence, an encouragement document has been sent, and it is also directly explained in the document that if Tiangong technology successfully completes these tasks, the official will consider it, Open up some technologies in the design and manufacturing of spacecraft and space station to Tiangong technology, and allow Tiangong technology to participate in the project of the new space station.


    When the rocket Department of Tiangong science and technology received this document sent by the official, it can be said that it caused a sensation in the whole rocket department, and it is also very looking forward to participating in the construction of the space station.


    .....


    In the rocket design and Manufacturing Laboratory of Tiangong technology, sun Lao and others are designing the latest rocket of Tiangong technology, that is, tiangong-6 rocket.


    "Sun Lao! How is the design of our latest rocket, tiangong-6 rocket, and when can it be completed?" Wang Bin asked sun Lao in the design room.


    Since the new rocket is a giant with a total weight of more than 1500 tons, a low orbit carrying capacity of 50 tons and a geosynchronous orbit carrying capacity of 35 tons, Wang Bin cannot ignore it.


    After all, if this rocket is developed, their Tiangong technology and ability to launch spacecraft can be greatly improved.


    Moreover, with this rocket, the satellite chain plan of Tiangong technology can also launch some high orbit satellites with relatively high weight in the satellite chain. At the same time, they can also discuss with the official whether they can start the construction of high orbit communication space base station and high orbit space laboratory.


    "Mr. Wang! The design of the rocket has been very smooth so far because of the information provided by Mr. Wang. The preliminary design drawing of the rocket has almost come out. Next, how to make this rocket.


    Because the size and weight of this rocket are our Tiangong technology, and even the largest, heaviest and most powerful rocket in China, it is naturally the most difficult in manufacturing.


    At the same time, compared with the Rockets we made before, the manufacturing time of this rocket will also be much longer. According to my estimation, even with the current rocket manufacturing capacity of Tiangong technology, it will take at least one or two months to manufacture one. If other companies or teams, even foreign companies, want to manufacture such a rocket, It will take at least half a year. After all, the rocket manufacturing equipment of Tiangong technology is the most advanced in the world.


    In addition, the manufacturing cost of this rocket is also very high, dozens of times that of the No. 5 rocket we designed and have begun to manufacture.


    Of course, when there is a professional production line for this rocket in the future, the manufacturing time and production cost of this rocket will be greatly reduced, "Sun said.


    After listening to sun Lao''s words, Wang Bin nodded, then asked about the tiangong-5 rocket, and got that when the type 5 rocket was about to be manufactured and could be launched, Wang Bin was also greatly relieved.


    We should know that for the first launch mission of the type 5 rocket, their Tiangong technology has also determined, that is, to send a relay communication satellite weighing about five tons to the lunar orbit 380000 kilometers away from the earth, so as to prepare the country and Tiangong technology for landing on the moon in the future.


    In addition, the type V rocket will also undertake the task of transporting materials for the space station, on orbit spacecraft and space laboratory, so as to reduce the burden on officials in this regard.


    Of course, with the start of the manufacture of the five type rocket, the topic of manned spaceflight of Tiangong technology has also been raised on the agenda. Therefore, their Aerospace Department of Tiangong technology has held many meetings.


    Moreover, these meetings were not held by Tiangong technology itself. Because these meetings are related to the overall situation of the official space industry, Qin Lao and other officials came to the meeting, and even other domestic space companies sent personnel to attend these meetings, such as Lanjian, China Eastern Airlines, etc.


    After all, aerospace is not a company''s business, but related to the official Aerospace layout.


    As for LAN Jian and China Eastern Airlines, due to their very limited technical strength, they can only launch rockets with a carrying capacity of less than five tons. Even the success rate of launching rockets with a carrying capacity of less than five tons is very limited, but anyway, they have entered the gate of aerospace, so they can also carry out official tasks from time to time.


    Of course, due to the rise of Tiangong technology, their two aerospace companies hope to buy some Tiangong technology. Of course, their technology is also the technology of rockets less than five tons, especially less than one ton.


    In this regard, after comprehensive consideration, Wang Bin decided to sell some of the technologies that they could manufacture. As for the parts and equipment that the other two companies could not manufacture, Wang Bin did not transfer the technology. After all, even if they bought these technologies, they could not manufacture them with their technical strength, even if they could barely manufacture them, But God knows if the products they make can be used.


    Therefore, at the meeting, Wang Bin promised the two companies that Tiangong technology could be sold to them, including rocket engines.
