Wu Hao's remarks really aroused the fighting spirit of everyone present, and also let everyone see Wu Hao's huge space program.

The thought of having the honor to participate in this project made everyone excited.

Looking at the countdown card on the wall, Wu Hao couldn't help but say: "It's less than thirty hours before the launch." ”

Yu Chengwu nodded and said: "

According to the meteorological satellite cloud map and the current national and regional weather data, there will be a launch window from 18 to 20 o'clock tomorrow evening, and we plan to launch at an opportune time during this period.

If the launch is terminated and postponed, it may be a few days later. ”

Wu Hao nodded when he heard this, then looked at the rocket monitoring screen in the middle of the big screen and said, "What is the situation of the rocket now, are you ready?" ”

Zhou Xiangming nodded and said: "Because we use a new type of semi-solid foamed propulsion fuel developed by ourselves, which is more convenient to store than conventional liquid rocket fuel, the fuel has been filled three days ago."

In addition, we have conducted two systematic tests and two launch exercises, and now we are conducting the third systematic test and launch exercise.

It is expected to be completed in the evening and can be transferred to the launch procedure. ”

Yu Chengwu added: "We have already gone to the area where the rocket wreckage may fall with the local authorities, done ideological work for the people, and evacuated it when it was launched. In addition, we also installed a Beidou locator on the rocket, which can track the specific location of the rocket wreckage in real time, so as to arrive at the scene for disposal as soon as possible.

In addition, we also cooperate with the satellite tracking and control center in Anxi and the island city, and they track and monitor the flight trajectory of rockets and satellites, and transmit them to me in real time.

At the same time, the tracking and monitoring data of the launch and the two satellite tracking and control centers will be uploaded to the Beijing Aerospace Flight Control Center, which will conduct real-time monitoring and command.

Of course, in general, they will not interfere with us unless there are special circumstances. ”

"Where's the satellite?" Wu Hao nodded and asked.

Yu Chengwu replied now: "The representatives of the developers of the three satellites have already arrived, and the final commissioning of the satellites is underway in the next few days, would you like to see them?" ”

Wu Hao shook his head with a smile and said, "Forget it, there is no need to make special arrangements." You should be able to meet tomorrow when you watch the launch, and you can just say hello when the time comes. ”

Hearing Wu Hao say this, Yu Chengwu also nodded and stopped talking.

After chatting for a while, Zou Xiaodong immediately proposed that he wanted to go to the rocket launch site to have a look, which couldn't help but arouse the interest of other casual personnel.

It stands to reason that after the rocket fuel refueling is completed, other idle personnel are not allowed to approach. However, they use a new type of semi-solid foamed propulsion fuel, which is still relatively reliable in terms of safety.

So Yu Chengwu immediately agreed to their request, and then everyone got into several open-top off-road vehicles at the base and drove towards the rocket launch site.

The launch site is about two or three kilometers away from the base, and the terrain is relatively flat, and the sand dunes that have been raised one after another have been bulldozed. So you can see the launch tower of the launch site and the white and blue rockets erected on the tower.

Although the rocket was less than thirty meters away, the closer it became, the more shocked everyone was by his majestic body. It is hard to imagine that such a large rocket can only carry less than three tons of items to low earth orbit. It has to be said that the funds and resources consumed by human beings flying into space in the future are absolutely huge, which is why the price of rocket launch payloads is so expensive.

Arriving at the launch site, after putting on the hard hats, everyone was finally able to look up close at the launch vehicle, which had been set up on the launch platform and was about to be launched.

Looking at this rocket, Yu Chengwu and Wu Hao's eyes couldn't help but soften. That feeling is like looking at your own child, and it is also a 'promising child'.

"This rocket was assembled horizontally in the final assembly test building at the base and tested for the first time. After the test is completed, the rocket will be handed over to our transport vehicle, which will transport the rocket to the launch site through the hardened road between our base and the launch site, and then erect it on the launch platform.

Compared with the vertical assembly adopted in our country, the technical difficulty and requirements of vertical and horizontal assembly and transportation will be much lower, and the corresponding cost will be much lower.

Of course, the whole process is complicated. For example, the hardened road we just walked on was specially paved with great effort.

Don't underestimate this road, the construction difficulty is very high, and its construction cost is enough to pave two airport runways. ”

Yu Chengwu saw everyone's surprise and said with a deep smile: "That's right, the cost is huge. Because the road should not only be straight, but also as smooth as possible, the horizontal difference of the entire road surface, we controlled it at five millimeters, which is a very high standard.

That is, from that end of the road to this section, the drop is less than half a centimeter.

Secondly, it requires the road to have ultra-high anti-subsidence and anti-compressive and anti-load capacity. Rockets of tens or hundreds of tons have to pass through above, and there are very strict requirements for the road and the foundation under the road.

This may not be much in the mainland, but this is a desert with sand underneath and is very easy to sink. Therefore, when building a road, we have to drive the pile foundation first, and then build the road on the pile foundation, which is equivalent to building a bridge with a super high standard.

Finally, there is the launch vehicle of this rocket, and we have introduced the world's most advanced self-propelled modular transporter. Not only does the car have a heavy load, but it can also be modularly assembled as needed, increasing the length as needed.

This means that we will be able to transfer longer and heavier rockets in the future. ”

Speaking of this, Yu Chengwu smiled a little embarrassedly: "However, according to the latest fixation of the space authorities, medium and heavy commercial launch vehicles such as those of our private companies must be launched at a regular launch center and handed over to the launch center.

In other words, we can only launch light rockets here in the future, and we need to apply to the space authorities a month in advance. ”

Wu Hao nodded when he heard this, and then asked, "Are there any problems or difficulties?" ”

Yu Chengwu shook his head with a wry smile and said, "It's not difficult, it's just more troublesome."

First of all, because the tunnels are limited, the diameter of the rocket that can be transported is actually limited, which is also one of the problems that restrict the launch of large rockets in the interior of our country.

It is also for this reason that our country decided to establish a launch center in the South China Sea to transport large rockets by port ship. ”
