Among these meteorological factors that affect the launch of rockets, the wind speed should have the greatest impact. If the wind speed is too large, it will affect the flight attitude of the rocket, which will lead to the flight reliability deviation of the rocket, and even make the launch fail. Even if you are lucky enough to launch a successful launch, you may be able to put a satellite or other payload on the wrong track.

The consequences of this are the failure of the satellite's function, or the failure to achieve the expected goal, the reduction of lifespan, and so on. In the worst case, the satellite may collide with other orbital satellites or spacecraft due to the wrong transportation orbit, which may cause a chain reaction and cause serious consequences.

Weather forecasting systems for large weather conditions will give more accurate forecasts, but it is difficult to predict the special microclimates formed in the region, or the circulation of small airflows, which is what we call gusty weather.

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

As for sand, 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, resulting in the failure of some sensors, or the failure of some precision instruments due to short circuits.

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

However, these rockets are specially designed, so they have no effect.

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

The first-level recyclable part is Wu Hao's new hybrid liquid fuel, which is Wu Hao's own rocket propulsion fuel, and has obtained relevant patents. Although the fuel is in a liquid state, it is not a pure liquid, but rather a bit like thicker milk, which makes the engine thrust greater.

Although the fuel is not affected by low temperatures, some 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 happened that in the past two days, a cold snap from Siberia had passed through, so Yu Chengwu and Zhou Xiangming were more worried.

As a matter of fact, as early as the beginning of the establishment of the launch site, Yu Chengwu and Zhou Xiangming were ready to establish a meteorological observation system within a radius of several hundred miles.

In the vast and sparsely populated desert, automatic weather observation stations with solar or wind energy are set up to collect relevant meteorological information. The meteorological information is then 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 predicted more accurately.

At present, this system has been preliminarily completed, and it has also played a great role.

But this launch is not only about a launch window and then launching the rocket into space, but also about reserving a landing time for the rocket.

Especially when landing, the rocket releases three large parachutes, which are more sensitive to the influence of meteorological information, especially wind speed.

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

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

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

This recyclable commercial launch vehicle is more technically difficult, so everyone has no bottom in their hearts. Therefore, everyone hopes to be foolproof before the rocket launch to ensure the success of the rocket launch and return.

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

The value of these two satellites is relatively high, and although they are insured, everyone is still quite apprehensive.

After all, it is the first round of cooperation with these institutions and companies, and 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 cooperate in the future.

And the second thing that everyone is worried about after all is that this time not only Wu Hao came to the town in person, but also invited giant celebrities such as 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 bitterly.

Wu Hao walked to his seat and sat down, then waved his hand at Yu Chengwu, Zhou Xiangming and the others and said, "Okay, you all go and get busy, don't worry about me, I'll just take a look." ”

Seeing that Wu Hao said this, everyone was not polite, and immediately began to get busy. And Zhou Xiangming nodded to Yu Chengwu, and then after saying hello to Wu Hao, he also hurried to get busy.

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

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

"What are these words?" Wu Hao laughed when he heard this.

"Recyclable rockets are much more complex than disposable rockets, and there are too many factors that can affect the launch of rockets. We are sure that we are not sure, but we will give it our all. ”

Looking at Yu Chengwu's premature and gray hair on his temples, Wu Hao smiled and comforted: "Just work hard, don't put too much pressure on yourself."

I heard that you haven't rested for a long time, and after this launch, whether it's successful or not, you should rest for a while, and wait until the New Year is over. ”

Yu Chengwu shook his head with a wry smile and said, "It's okay to say that you can rest for a few days. But if you fail, if you don't find out the cause and solve it, how can you rest with peace of mind? ”

"Don't put that much pressure on yourself." Wu Hao looked at him and persuaded: "This project can't be completed in a day or two, the coming day is long, you still have more tasks on your body, you have to take care of your body." ”

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

"When that launch mission is done in March, we'll take a little rest. At that time, the weather was also warm, and we could also go on 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. ”

"Well, Mr. Wu, I'm afraid you're not qualified to talk about me in this regard, I heard that your longest record has not come out in the drilling laboratory for more than ten days."

Wu Hao: ......
