However, when the aircraft frame of Tiangong Technology came out of the painting workshop and entered the final assembly workshop again, Wang Bin, who wanted to continue the final assembly of this aircraft in the workshop, had to come out of the workshop.

Because after these few days of assembly work, their second Tiangong-4 rocket of Tiangong Technology has been assembled and erected on the launch pad.

At the same time, their Tiangong Technology's first deep-space satellite has also completed the research and development and assembly work, and has also been installed on the rocket, just waiting for launch.

Of course, according to the original plan, the rocket should have been launched a few days ago.

However, due to the unfavorable weather conditions these days, the rocket has not been launched during this period of time.

According to the weather forecast, today's weather will be very good, so Tiangong Technology decided to launch the rocket this afternoon after learning about the weather conditions a few days ago.

Of course, before the launch of this rocket, Tiangong Technology had already reported this matter to the superior, and had obtained the consent of the superior.

Of course, with Wang Bin and his Tiangong Technology successfully manufacturing this satellite, it also means that Tiangong Technology has successfully and initially mastered the satellite manufacturing technology, and it is also the manufacturing technology of deep space exploration communication and relay satellites.

In fact, in general, compared with rocket manufacturing technology, satellite manufacturing technology is relatively simpler. Of course, this is only compared to low-earth orbit satellites that are not technically complicated and have a single function.

Because in an environment like space, satellites must consider a variety of factors, such as weightlessness, high radiation, high temperature, low temperature, impact of meteorite fragments, and so on.

It is precisely because of this that the requirements for satellite materials are very high, and their Tiangong Technology has made good achievements in materials.

As for the satellite designed and manufactured by Tiangong Technology, its technical difficulty is much greater, even compared with rocket technology, it is not much better.

First of all, it is natural that the weight of this satellite has reached more than ten tons, and this satellite has many functions. At the same time, the orbit of the satellite is outside the geosynchronous orbit. means of communication.

As the launch time approached, Wang Bin came to the console of Tiangong Technology's rocket launch site. At the same time, Wang Bin was still a little excited.

After all, the satellite launched this time is the first time that Tiangong Technology has launched a space vehicle developed and manufactured by itself. Although Tiangong Technology already had the ability to launch a variety of rockets before, what they launched was basically It is an official satellite, and has never launched its own satellite.

Of course, this is also related to the fact that Tiangong Technology did not have this need before, but it is different now. Due to the formal proposal of Tiangong Technology’s deep space star chain plan, it is foreseeable that most of the rockets launched by Tiangong Technology in the future will be will be equipped with their own satellites of Tiangong Technology,

Logically speaking, since Tiangong Technology is developing satellites for the first time, it should be honest and step-by-step, first developing low-orbit small satellites with a single function and less complicated technology, but Tiangong Technology directly develops satellites outside the geosynchronous orbit. It is a high-orbit satellite, and it is also a satellite with complex functions.

At the Tiangong Science and Technology rocket launch site, a slender rocket was standing there at this time, but Wang Bin found that this Tiangong-4 rocket seemed a little different from the first Tiangong-4 rocket before. That is the fairing of this rocket, which is much larger than the one launched before, and its diameter is even larger than the core stage of the rocket. At the same time,

The length of this fairing is also much longer, reaching about ten meters long, and the length and diameter of the fairing of the rocket launched before are not as large as now.

It is precisely because of this that Wang Bin feels that this rocket is a bit different from the previous ones. After all, under the current situation, this rocket looks much bigger, and at the same time it feels longer.

But there is no way around this. Although the satellite developed by Wang Bin and Tiangong Technology this time only weighs about ten tons, but because Tiangong Technology is the first to develop a satellite and it is still a satellite with complex functions, so in terms of technology , is still a bit rusty, and because the trajectory of this satellite is outside the synchronous orbit, more factors must be considered than low-orbit satellites. The first requirement is also very long, and it must have the ability to operate for more than 50 years.

Therefore, the satellites developed by Tiangong Technology are so large in size and heavy in tonnage.

Of course, since the satellite launched this time was developed by Tiangong Technology itself, and the orbit is outside the synchronous orbit, this satellite is also the first satellite of the Deep Space Starlink project.

So the launch of this satellite this time has naturally received great attention from the authorities. The entire control center has been crowded with satellite experts and aerospace workers who have heard the news. At the same time, these experts are They were all discussing something in a low voice, including Mr. Qin, the person in charge of the aerospace department.

Wang Bin looked at the rocket in the middle of the launch pad quietly, and beside the rocket, there were many people busy at this time. Wang Bin knew that this was the technician of their Tiangong Technology rocket, and they were working on the rocket. Final check.

At the same time, there are no aircrafts flying in the sky over the rocket launch at this time, even some civilian drones. It is obvious that the sky near the Tiangong Technology rocket launch site has been banned at this time.

"Mr. Wang! The rocket is in good condition, the fuel has been added, and it can be launched at any time. May I ask if the launch mission is carried out as planned?" Mr. Sun came over and said to Wang Bin.

"Execute according to the original launch plan." Wang Bin turned his gaze to the side and asked the person in charge of the launch, Sun Lao said.

Just after Wang Bin finished speaking, the staff at the launch site also began to evacuate one after another, and the countdown to the rocket launch also started.

"30.29.28...3.2.1! Ignition! Launch!" As the countdown to the rocket launch ended, the controller on the launch pad beside him gently pressed the red rocket ignition launch button and stood upright. The Tiangong-4 rocket in the launch site immediately ejected countless hot flames from its tail, and the Tiangong-4 rocket also began to slowly leave the ground.

At the same time, when the rocket is ignited, countless water jets are sprayed out on the rocket launch pad, and they are quickly vaporized after contact with the flames sprayed by the rocket, so as to reduce the impact of the flames sprayed by the rocket on the launch pad. At the same time, the water vapor can also effectively suppress the loud noise produced by the rocket launch.

At this time, as the height of the Tiangong-4 rocket rose, the color of the flames ejected from the rocket also changed. From the original orange red, it soon became completely transparent white. As you can imagine, At this time, how high is the temperature of the flame sprayed by the rocket, and how harsh the operating environment the rocket engine needs to withstand.
