Among these meteorological factors affecting rocket launches, the most influential one should be wind speed. If the wind speed is too high, it will affect the rocket's flight attitude, which will lead to deviations in the rocket's flight safety, and even cause the launch to fail. Even if the launch is successful with good luck, it may transport satellites and other payloads to the wrong orbit.

Such consequences range from satellite function failure, or that the expected goal is not achieved, life expectancy is reduced, and so on. On the other hand, due to the wrong transportation orbit, the satellite may collide with other orbiting satellites or spacecraft, which may cause a chain reaction and cause serious consequences.

The meteorological forecast system will give relatively accurate forecasts for major weather conditions, but it is difficult to forecast accurately the special microclimate formed in the region, or the small air circulation, which is what we call gust weather.

Especially in this kind of sparsely populated and vast desert, there are relatively few weather stations set up by the meteorological department, 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. Tiny particles in the dust may enter the precision equipment in the rocket body, causing some sensors to fail, or some precision instruments to short-circuit and malfunction.

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

However, these rockets are 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 propellant developed by Wu Hao and the others themselves, and has obtained related patents. Although this kind of fuel is in a liquid state, it is not a pure liquid. Instead, it is somewhat like thicker milk, which makes the thrust of the engine greater.

Although the fuel is not affected by low temperature, some catalysts like fuel mixing are not very resistant to low temperature, 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 the ignition stage before takeoff. Coinciding with these two days, the cold current from Siberia passed through, so Yu Chengwu and Zhou Xiangming were worried.

In fact, Yu Chengwu and Zhou Xiangming planned to establish a meteorological observation system within a radius of hundreds of miles as early as the beginning of the establishment of the launch site.

In the sparsely populated vast and endless desert, an automatic weather observation station with solar or wind power is set up to collect relevant weather information. The meteorological information is then integrated with the data of the meteorological system in the nearby area and the national meteorological system, so that the meteorological conditions of the launch site can be more accurately forecasted.

At present, this system has been preliminarily established and has played a great role.

But this launch does not only need a launch window, and then the rocket will be launched smoothly into the sky, but also a landing time must be reserved for the rocket.

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

So until the last moment, Yu Chengwu and Zhou Xiangming didn't know what to do.

When we came to the command and control center of the launch site, it was brightly lit and a busy scene. Compared with the last rocket launch, everyone is obviously busier this time.

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

The technical difficulty of this recyclable commercial launch vehicle is even more difficult, so everyone has no idea. So everyone hopes to be foolproof before the rocket launch to ensure the success of the rocket launch and return.

Especially for all members of the entire project team, what is even more terrible is the two satellites carried by 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 they are insured, everyone is still quite nervous.

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 their project development process. In this way, it will be more difficult to cooperate in the future.

And the second thing everyone is worried about is that not only Wu Hao came to sit in the town in person this time, but also invited giants and celebrities like Lao Ma and Xiao Ma to watch on the spot.

If there is something wrong with me 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 wryly.

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

Seeing what Wu Hao said, everyone was not polite, and immediately started to get busy. On the other hand, Zhou Xiangming nodded to Yu Chengwu, greeted Wu Hao, and hurried to get busy.

Wu Hao looked at Yu Chengwu who was sitting beside him and said, "How about it, do you have confidence?"

Yu Chengwu shook his head with a smile and said, "I have confidence, but I'm just not sure."

"What's that?" Wu Hao laughed when he heard the words.

"Recoverable rockets are much more complicated than disposable rockets in terms of structure, and there are too many factors that can affect rocket launches. There is absolutely no certainty, but we must do our best."

Looking at Yu Chengwu's prematurely aging, gray hair at the temples, Wu Hao comforted him with a smile: "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, no matter whether it is successful or not, you should take a good rest for a while, and wait until the year is over. "

Yu Chengwu smiled wryly and shook his head, "It's okay to be successful. You can rest for a few days. But if you fail, if you don't find out the reason and solve it, how can you rest in peace."

"Don't put so much pressure on yourself." Wu Hao looked at him and persuaded: "This project can't be completed in a day or two. The future will be long, and you still have many tasks on your body. You have to take care of your health."

"Don't worry, Mr. Wu, every morning a group of us are running around the base for fitness, and our bodies can bear it." Yu Chengwu said with a smile.

"After the launch mission in March is completed, we will take a short rest. It happens that the weather is warmer at that time, and we can also take a good vacation."

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

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

"Uh, Mr. Wu, I'm afraid you're not qualified to say anything about me. I heard that your longest record is that you haven't come out of the lab for more than ten days."

Wu Hao: ...
