During the chat between Wang Bin and the person in charge, it soon came to the time of rocket launch, and the person in charge of rocket launch also returned to his post at this time, while 300 himself quietly looked at the rocket standing on the launch pad, and his heart was looking forward to their first satellite being developed by Tiangong technology.


    Although it is the research and development of spacecraft and satellites, as early as the first rocket of Tiangong technology began to be developed and manufactured, Wang Bin''s Tiangong technology has already begun to be developed.


    However, they have developed four kinds of rockets in the research and development of rockets, but the progress in the research and development of spacecraft is not so fast. Until now, the first satellite of Tiangong technology is still in the research and development stage.


    Of course, this does not mean that their research and development of Tiangong technology in the research and development of satellites and other spacecraft is not smooth. On the contrary, in fact, their research and development of the first spacecraft is very smooth.


    This is because although it is the first time for Tiangong technology to develop spacecraft, Tiangong technology does not want to start research and development from the simplest small satellites like other aerospace companies, and then develop medium and large satellites with higher technology and more complex structure.


    This time, the spacecraft developed by their Institute of space technology is not an ordinary spacecraft, but a high orbit deep space communication satellite based on the official deep space communication system. This satellite should not only have the ability of deep space communication, but also have the ability of relay satellite, but also have certain deep space exploration and exploration within 10000 kilometers around the earth, At the same time, it also provides interstellar navigation for various spacecraft near the earth to avoid space traffic accidents.


    Therefore, the satellite they are developing now by Tiangong technology is very technically difficult and its structure is very complex. In addition, there were not many R & D personnel of Tiangong technology in satellites and other spacecraft before.


    At the same time, the weight of the satellite to be developed by Tiangong technology is expected to reach about 10 tons. Before, their Tiangong technology rocket did not have the ability to send such a weight satellite to geosynchronous orbit, so there was no hurry in research and development.


    Fortunately, with the successful development of tiangong-4 rocket of Tiangong technology, now the first deep space communication and navigation satellite developed by Tiangong technology will also be developed successfully.


    In other words, it won''t be long before they can launch their own satellites with their own rockets. Wang Bin naturally looks forward to this.


    Just when Wang Bin was thinking about his Tiangong technology satellite, the countdown to rocket launch had sounded in the control room, and all the personnel in the rocket control room were concentrating on the computer in front of them.


    With the end of the countdown, the rocket ignited successfully and rose slowly at the command of the person in charge. At this time, Wang Bin also looked at the rocket on the launch pad.


    As the rocket climbed, it soon disappeared in the eyes of the public. Wang Bin looked at the animation video of the rocket launch.


    In fact, at this time, there was no trace of tension in Wang Bin''s heart. Perhaps he had experienced more rocket launches, or his confidence in the rocket developed by Tiangong technology.


    In short, when the rocket was successfully launched and recovered, Wang Bin was a little excited and clapped with the people in the control room.


    Of course, at this time, the personnel in the control room also clapped their hands one after another, but they were not as excited as when they successfully launched the rocket for the first time.


    "Sun Lao! This heavy rocket we designed is very successful! Not only in the launch process, but also in successfully sending the spacecraft into the predetermined orbit, and even in the recovery of all levels of the rocket, it is also very successful. You owe the most to sun Lao!" Wang Bin said.


    "Mr. Wang! This is not my own credit. After all, the R & D and manufacturing of rockets is a huge project, which can never be completed by me alone. Therefore, all this is the result of the joint efforts of our Tiangong rocket R & D and manufacturing personnel.


    In addition, there is president Wang. The technology and data you provided are the most important reason why Tiangong technology can develop and manufacture this rocket in such a short time. Therefore, if you insist that whoever contributes the most, no one can compare with President Wang! "Sun said with a smile.


    After listening to sun Lao''s words, Wang Bin didn''t say anything, but smiled.


    In fact, Mr. Sun is indeed very correct in some aspects. Not to mention the equipment for manufacturing rockets, Wang Bin bought them from the mall. For this reason, Wang Bin paid a lot of energy coins.


    After all, the equipment that can make rockets is not cheap. In addition, there are rocket fuel manufacturing equipment, and the price is not cheap.


    Since these rockets developed by Tiangong Technology Institute are liquid hydrogen and oxygen fuel rockets, Wang Bin and Tiangong technology adopt the method of extracting from water to obtain liquid hydrogen and liquid oxygen.


    After all, water is the easiest raw material to obtain than it is extracted from other substances.


    However, compared with extracting from other substances, it is not difficult to obtain liquid hydrogen and liquid oxygen from water, which can be obtained by electrolysis.


    However, at the current level of human civilization, the cost of obtaining liquid hydrogen and liquid oxygen from water is not small. Taking electrolytic water as an example, it needs huge electricity for electrolysis.


    After all, according to the current scientific and technological level, electrolysis of a kilogram of hydrogen also requires at least 33 degrees of electricity, and 33000 degrees of electricity for a ton of hydrogen. If you want to activate liquid hydrogen, you need more electricity.


    A heavy rocket needs at least hundreds of tons of liquid hydrogen. Only one rocket needs the electricity for liquid hydrogen electrolysis, which needs millions of degrees.


    However, although Tiangong technology also uses electrolytic water to obtain hydrogen and oxygen, the power required is very little, even only one tenth of the original level.


    This is because the way of electrolyzing water adopted by Tiangong technology is different from the traditional way. In addition, some additives are added to the water, which greatly increases the efficiency of electrolyzing water. Therefore, the cost of launching rocket fuel is greatly reduced.


    Whether it''s the new electrolytic water technology or equipment, Wang Bin spent a huge amount of energy money to buy it from the science and technology mall. Therefore, Mr. Sun would say that Wang Bin was the first to develop and manufacture the first heavy rocket so quickly.


    At the same time, Wang Bin can also foresee that with the successful development of the first heavy rocket of Tiangong technology, the frequency of launching rockets by Wang Bin and Tiangong technology will also be greatly improved.


    After all, although the first rocket of Tiangong technology will not be reused because it is used for commemoration, the second tiangong-4 heavy rocket of Tiangong technology has already been manufactured when the first rocket was manufactured, and now it has to be completed, and the second rocket will be reused in the future, And it should be reused at least ten times.
