As the Jianmu-9 rocket carried the Lunar Cargo-2 spacecraft from the vertical assembly plant to the launch tower, the countdown to this mission also entered.
As the person in charge of this project, Zhou Xiangming led his team to the Nanhai Space Launch Site and made final preparations for the launch mission together with the scientific research and technical personnel who had arrived there earlier.
As for Yu Chengwu, he stayed behind in Anxi and took command.
As for Wu Hao and the others, they have been paying close attention to this launch mission.
To be honest, because this mission received special attention, it also made Wu Hao and the others feel a little pressure. Not to mention the scientific researchers below, so Wu Hao and others have been decompressing everyone these days.
In the office, Wu Hao and Zhang Jun sat together and listened quietly to Yu Chengwu's report there.
In fact, this is a small working meeting to hear about the preparations made by Yu Chengwu and the others in recent days.
"...Currently, our work is progressing smoothly, and the rocket will be launched at 8:10 pm on the 25th."
After listening to Yu Chengwu's report, Wu Hao and the others nodded.
Wu Hao looked at Yu Chengwu and asked, "The launch time has been determined."
Yu Chengwu nodded: "Through our communication and research with the meteorological system, from 5 pm to 10 pm on the 25th, the meteorological conditions at the Nanhai Space Launch Site and the surrounding sea areas, including the lander's scheduled landing sea area, meet the needs of rocket launch, so We determined this time and reported it to the launch site and superior authorities, and received approval."
"What's the current status of the rocket and spacecraft?" This time the question was asked by Yang Fan. As the company's chief technology officer, Yang Fan also has a say in this aspect.
And as a shareholder of the company, Yang Fan has the right to intervene in this matter.
So after hearing Yang Fan's inquiry, Yu Chengwu immediately responded: "The rocket and spacecraft are currently in good condition. We have begun to refuel the rocket and conduct final tests and rehearsals."
Speaking of this, Yu Chengwu smiled and said: "Generally, the fuel refueling time of the rocket is completed twenty-four hours before the rocket is launched, or even within twelve hours.
This is mainly because conventional rockets either use highly corrosive toxic fuels, or liquid hydrogen and liquid oxygen fuels, and then kerosene and methane, but they also need oxygen as a combustion support.
Liquid hydrogen and liquid oxygen are low-temperature fuels. If the filling time is too long, the ultra-low temperature will affect the rocket body materials, cause metal fatigue, and also affect and damage some electrical circuits in the rocket, causing rocket failure.
We use self-developed semi-solid foam propulsion fuel, which has many advantages over conventional propulsion fuel. First of all, it is cheap. Its cost is cheaper than liquid hydrogen and liquid oxygen fuel, and it is similar to the cost of methane and kerosene fuel.
The second is stability. This kind of fuel is very stable and not volatile, so it is suitable for long-term storage. So there is no problem for us to refuel in advance.
This can save us very precious time before launch, so that we can carry out a lot of preparation work. At the same time, it can also shorten the launch preparation time by half. "
“As for the spacecraft, we have also conducted repeated tests and inspections, and only carried out vertical assembly after confirming that there are no problems.
And thanks to our excellent achievements in artificial intelligence technology, we have also applied artificial intelligence technology to the control system of the spacecraft, which also makes the control system of the spacecraft more intelligent, and it can monitor the status of the spacecraft in real time. And accurately identify the problems on the spacecraft so that our technicians can solve them promptly and quickly.
At the same time, this intelligent control system can also play a huge role in the flight of the spacecraft. It can adjust independently according to the status of the spacecraft, thereby ensuring that the spacecraft can more accurately execute various preset instructions and remote control instructions.
In addition, it can also accurately troubleshoot and solve various system problems that may occur on the spacecraft. Therefore, with the help of this system, the reliability of the spacecraft will be greatly improved. "
After listening to Yu Chengwu's introduction, everyone nodded. In fact, they all know these things. Yu Chengwu's report at this time is undoubtedly to send a signal to them, that is, they are very confident in this launch mission.
Wu Hao and the others were naturally very satisfied with this.
Looking at Yu Chengwu's slightly haggard face, Wu Hao said with a smile: "Don't put too much pressure on yourself, and don't put too much pressure on everyone, this is just an ordinary mission.
Although there is a lot of attention on this mission from outside, it is nothing. For us, this is just an ordinary mission. We are by no means people who cannot afford to lose and refuse to accept failure, so don’t feel any psychological pressure and just try your best. "
Zhang Jun on the side also nodded and said: "The reason why this mission has such a high level of attention is also inseparable from the hype of some people with ulterior motives overseas.
The purpose of their hype is nothing more than to exaggerate our dangers. Who can hide this kind of trick?
So for us, just treat it with a normal mind and don't be disturbed by external information. Of course we know the risks involved in this mission. It should be said that any space mission has risks. Whether it is a rocket launch or a spacecraft landing on the moon, they are high-risk missions. Therefore, when we prepare for success, we are also prepared for failure. preparation.
It should be said that everything is actually under our consideration, so you don't have to worry too much.
Of course we will be happy if it succeeds. If it fails, it is just a launch mission. We will lose more money, time and delay the project progress at any time.
It doesn't matter, we still have a long time, so take your time. "
After listening to Zhang Jun's words, Yu Chengwu nodded and said, "Thank you leaders for your concern. We will definitely go all out to make this mission a complete success."
Wu Hao smiled and shook his head when he heard this. He also knew that all the persuasion was in vain. As long as the launch was not completed, the pressure on these people would not be relieved.
Even if Wu Hao and the others don't force them, they will force themselves and put pressure on themselves.
Thinking of this, Wu Hao said to Yu Chengwu: "I don't care what you are thinking or how violent you are, we must do a good job of psychological counseling for our ordinary scientific research and technical personnel, so that everyone can go into battle easily and work happily.
It is strictly forbidden to transfer your pressure to them, and you are not allowed to put pressure on them. At the same time, we must also do a good job in ensuring the livelihood of employees at work. Don't be stingy in this regard, and do everything with high standards.
This is equivalent to fighting a war, and logistics determines the success or failure of this battle. "
