While Wang Bin was chatting with the person in charge, it was soon time for the rocket to launch, and the person in charge of the rocket launch also returned to his post at this time, while Sanbai himself was watching quietly. This rocket on the launch pad, but in my heart I am looking forward to the first satellite that they are developing by Tiangong Technology.

Although it is for the research and development of spacecraft and satellites, as early as when Tiangong Technology's first rocket began to be developed and manufactured, Wang Bin's Tiangong Technology had already started research and development.

However, Tiangong Technology has developed four types of rockets in the research and development of rockets, but in terms of spacecraft research and development, the progress has not been so fast. Until now, the first satellite of Tiangong Technology has also Still in development stage.

Of course, this is not to say that their Tiangong Technology's research and development of satellites and other spacecraft has not been smooth. On the contrary, in fact, the research and development of their first spacecraft developed by Tiangong Technology has been very smooth.

This is because Tiangong Technology, although it is the first time to develop a spacecraft, Tiangong Technology does not want to start research and development from the simplest small satellites like other aerospace companies, and then develop more technologically advanced and more complex structures. Medium and large satellites.

This time, the spacecraft developed by Tiangong Technology is not an ordinary spacecraft, but a high-orbit deep space communication satellite based on the official deep space communication system, and this satellite must not only have deep space communication capabilities , but also have the ability to relay satellites, and at the same time have a certain amount of deep space exploration and the ability to detect celestial bodies with a volume larger than one grain of rice within 10,000 kilometers near the earth. Provide interstellar navigation and the ability to avoid space traffic accidents.

Therefore, the satellite that Tiangong Technology is currently developing has a very high technical difficulty and a very complicated structure. In addition, there were not many R\u0026D personnel in Tiangong Technology in satellites and other spacecraft before.

At the same time, due to the weight of the satellite to be developed by Tiangong Technology, it is expected to reach about ten tons. Previously, their rockets of Tiangong Technology did not have the ability to send satellites of this weight to geosynchronous orbit, so the research and development aspects also Soldiers are not in a hurry.

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 successfully developed.

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

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

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

As the rocket climbed, it quickly disappeared from everyone's eyes. Wang Bin looked at the animation video of the rocket launch.

In fact, at this time, Wang Bin didn't feel any tension in his heart. Maybe it was because he had experienced too many rocket launches, or maybe it was because of his confidence in the rocket developed by Tiangong Technology.

In short, when the rocket was successfully launched and recovered, Wang Bin felt a little bit of excitement in his heart at this time, and applauded together with the people in the control room.

Of course, the people in the control room applauded one after another, but they were not as excited as they were when they successfully launched the rocket for the first time.

"Old Sun! This heavy rocket we designed,

It can be said to be very successful! Not only was the launch process very smooth, the spacecraft was successfully sent into the predetermined orbit, and even the recovery of the rocket at all levels was also very successful. All of this is due to you, Mr. Sun! "Wang Bin said.

"Mr. Wang! This is not due to me alone. After all, the development and manufacture of rockets is a huge project, and it is absolutely impossible to complete it by me alone. The result of the joint efforts of the manufacturing personnel.

In addition, Mr. 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 period of time. You have made the greatest contribution, and no one can compare to you, Mr. Wang! "Sun Lao said with a smile.

After hearing what Sun Lao said, Wang Bin didn't say anything, but smiled slightly.

In fact, what Sun Lao said was indeed very correct in some respects. Let alone the equipment for making rockets, Wang Bin bought them from the mall. For this, 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 the rockets developed by Tiangong Technology are all liquid hydrogen-oxygen fueled rockets, Wang Bin and his team at Tiangong Technology adopted the method of extracting liquid hydrogen and oxygen to obtain them.

After all, water is the easiest raw material to obtain compared to its extraction from other substances.

However, compared to extracting from other substances, it is not difficult to obtain liquid hydrogen and liquid oxygen from water, as long as electrolysis is performed.

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

After all, according to the current level of technology, at least 33 kilowatt-hours of electricity are needed to electrolyze one kilogram of hydrogen, and 33,000 kilowatt-hours of electricity for one ton of hydrogen. Even more electricity is needed to move liquid hydrogen.

And a heavy-duty rocket requires at least hundreds of tons of liquid hydrogen, and the power required for the electrolysis of liquid hydrogen required by just one rocket requires tens of millions of kilowatt-hours.

However, although Tiangong Technology also uses electrolysis of water to obtain hydrogen and oxygen, the power required is very small, even only one-tenth of the original level.

This is because the method of electrolyzing water used by Tiangong Technology is different from the traditional method, and some additives are added to the water, which greatly increases the efficiency of electrolyzing water. Therefore, the cost of launching rocket fuel is greatly increased. decreased.

Regardless of whether it is the new electrolyzed water technology or equipment, Wang Bin spent a huge amount of energy coins to buy it from the technology mall. That's why Mr. Sun said that the reason why Tiangong Technology was able to develop and manufacture it so quickly Wang Bin was the first to produce the first heavy rocket.

At the same time, Wang Bin can also foresee that with the successful development of Tiangong Technology's first heavy-duty rocket, the frequency of Wang Bin and his Tiangong Technology's rocket launch will also be greatly increased.

After all, their first rocket of Tiangong Technology, although it will not be reused because it will be used for commemoration, but the second Tiangong-4 heavy rocket of Tiangong Technology has already been used in the first rocket. When the rocket was manufactured, it had already started, and now it is about to be completed, and the second rocket will be reused in the future, and it will be reused at least ten times.
