Among the meteorological factors that affect rocket launches, the wind speed should be the most influential. If the wind speed is too high, it will affect the rocket's flight attitude, which will cause the rocket to fly at ease and even cause the launch to fail. Even if the launch is successful with luck, the satellite and other payloads may be transported to the wrong orbit.

Such consequences may be minor failure of the satellite function, or failure to achieve the expected goal, reduced life span, etc. On the other hand, the transportation orbit error may cause the satellite to collide with other orbiting satellites or spacecraft, which may cause a chain reaction and cause serious consequences.

The weather forecast system will give more accurate forecasts for large weather conditions, but it is difficult to accurately forecast the special microclimate or small air circulation formed in the area, which is what we call gusty weather.

Especially in this kind of sparsely populated and vast desert, the meteorological department set up relatively few weather stations, so it is difficult to capture the weather conditions in this area.

As for dust, it can be said that it is the number one enemy of many precision equipment. The tiny particles in the sand and dust may enter the precision equipment in the rocket body, causing some sensors to fail, or some precision instruments are short-circuited and malfunctioning.

In contrast, the impact of low temperature is relatively small. Especially for some "ice arrows", that is, hydrogen-oxygen fuel cryogenic rockets, the impact is relatively small.

However, this type of rocket is specially designed, so it has no effect.

This time, the second stage rocket of the Jianmu-2 recoverable rocket uses a hydrogen-oxygen engine and hydrogen-oxygen fuel.

The first-level recyclable part is Wu Hao's new mixed liquid fuel, which is a rocket propulsion fuel developed by Wu Hao themselves, and has obtained related patents. Although this fuel is in a liquid state, it is not simply a liquid, but rather like a thicker milk, which makes the engine more powerful.

Although the fuel is not affected by low temperature, some of the catalysts, such as fuel mixing, are not very resistant to low temperatures, so if the temperature is too low, it will affect the performance of the rocket.

Therefore, there are certain requirements for the temperature of the launch site, especially during the ignition phase before takeoff. It coincided with these two days that the cold current from Siberia passed by, so Yu Chengwu and Zhou Xiangming were more worried.

In fact, as early as the launch site was established, Yu Chengwu and Zhou Xiangming were preparing to establish a meteorological observation system within a radius of hundreds of miles.

In the vast and sparsely populated desert, automatic weather observation stations based on solar or wind energy are set up to collect relevant weather information. Then the meteorological information is integrated with the data of the meteorological system and the national meteorological system in the nearby area, so that the meteorological conditions of the launch site can be forecasted more accurately.

At present, this system has been initially completed, and it has also played a significant role.

But this launch does not only require a launch window, and then launch the rocket smoothly into the air, it also has to allow a time for the rocket to land.

Especially when landing, the rocket will release three large retarders, which is more sensitive to weather information, especially wind speed.

So before the last moment, Yu Chengwu and Zhou Xiangming had no bottom in their hearts.

Came to the command and control center of the launch site, which was brightly lit and a busy scene. Compared with the last rocket launch, everyone is obviously more busy this time.

Not only is the launch process of this recoverable rocket more complicated, but also because this is their first recoverable commercial launch vehicle.

This recyclable commercial launch vehicle is more technically difficult, so everyone has no idea. So everyone hopes to be foolproof before the rocket launch to ensure that the rocket launch and return are successful.

Especially for all members of the entire project team, what is even more terrible is the two satellites carried on the rocket this time. One is a scientific experiment satellite from a research institute, and the other is a ground remote sensing observation satellite from a commercial company.

The value of these two satellites is relatively high. Although there is insurance, everyone is still quite worried.

After all, it is the first round of cooperation with these institutions and companies. If it fails, although there is insurance to compensate, it will delay the project development process. As a result, it will be more difficult to think about cooperation in the future.

And the second thing everyone is worried about is that this time not only Wu Hao has come to sit down in person, but he also invited giant celebrities like Lao Ma and Xiao Ma to watch it on the spot.

If there is something wrong with this, and the launch fails, it will have a great impact on future projects. Thinking about the days to come, everyone couldn't help but smile.

Wu Hao walked to the seat and sat down, then waved his hands at Yu Chengwu, Zhou Xiangming and the others: "Okay, you all go and work, don't worry about me, I will just take a look."

Seeing Wu Hao said so, everyone was not polite, and immediately began to get busy. And Zhou Xiangming nodded to Yu Chengwu, then greeted Wu Hao, and hurried to get busy.

Wu Hao looked at Yu Chengwu who was sitting next to him and said: "How about, UU reading www.uukānshu.com is confident."

Yu Chengwu smiled and shook his head: "I have confidence, but I'm not sure."

"What are these words?" Wu Hao laughed at the words.

"Recoverable rockets are much more complicated than disposable rockets in terms of structure, and there are too many factors that can affect the launch of the rocket. There is definitely no full confidence, but we must go all out."

Seeing Yu Chengwu's premature decay, with some gray hair on the temples, Wu Hao smiled and comforted: "Just work hard, don't put too much pressure on yourself.

I heard that you have not rested for a long time. After this launch, regardless of success or failure, you should take a good rest for a while, and wait for the year to pass. "

Yu Chengwu smiled bitterly and shook his head and said, "Success is okay. I can rest for a few days. But if you fail, how can you rest assured if you don't find out the cause and solve it."

"Don't put so much pressure on yourself." Wu Hao looked at him and persuaded: "This project will not be completed in a day or two. It will be a long time in the future. You have more tasks on your body, so take care of your body."

"Don't worry, Mr. Wu, a group of us are running around the base every morning for fitness, and we can hold it." Yu Chengwu smiled.

"After the launch mission in March is completed, we will rest for a while. At that time, the weather is also warm, and we can also take a good vacation."

Hearing this, Wu Hao nodded and said with a smile: "That's good, anyway, you arrange and coordinate the relationship between work and life.

Work is important, life is equally important, don’t forget about life for work. "

"Um, Mr. Wu, I'm afraid you are not qualified to talk about me in this regard. I heard that your longest record is not coming out in the laboratory for more than ten days."

Wu Hao:...
