As the launch time gets closer and closer, the Internet is also paying attention to this launch mission. Not only did many bloggers and anchors come to the coast of the South China Sea, they opened related live broadcast rooms to broadcast the whole process.

The official website and official community platform account of Haoyu Aerospace, Haoyu Technology, as well as the official accounts of the virtual world and virtual reality world also conducted simultaneous live broadcasts.

In addition to the Internet, the TV station has also launched special programs on news channels and Asian channels, with live broadcasts on Qiancheng. There are even live broadcast rooms set up on the official accounts of multiple TV stations to broadcast the entire process.

In various forums, netizens are eagerly looking forward to this mission. Especially in the aerospace forum and the lunar forum, a group of enthusiasts and fans were extremely excited, watching the live broadcast and discussing enthusiastically.

The revolving platform begins to open.

I really opened it and finally saw the whole picture of Jianmu No. 9.

Why is it opened so early? Isn't it usually opened one hour before launch?

Yes, I asked why it opened so early today.

Generally speaking, the opening of the rotary platform is determined based on various situations, and the opening time of different tasks is different. For example, manned launch missions are usually fully opened half an hour before launch. Some missions are opened an hour before launch, and some missions may be opened several hours before launch.

What was said above is correct. The opening of the revolving platform is comprehensively determined based on the launch mission, weather, rocket, and other conditions. The weather looks good today, so I opened it early.

It’s not just the weather, it has a lot to do with the rockets. Haoyu Aerospace's Jianmu series rockets use self-developed semi-solid foam propulsion fuel instead of liquid oxygen kerosene, liquid oxygen, liquid hydrogen, or unbiased dimethylhydrazine used by other large rockets. These fuels need to be filled before launch, and the filling process is very complicated. After filling is completed, you need to launch quickly, otherwise the rocket fuel may corrode the fuel tank and pipelines in the rocket body, causing damage to the lines. In addition, liquid oxygen and liquid hydrogen fuel are low-temperature fuels. When the rocket body materials are in a low temperature state for a long time, it will also affect the characteristics of these materials, causing problems.

Continuing from the previous article: There is not much information disclosed about the semi-solid foam propulsion fuel used by Haoyu Aerospace. It is said that the formula is currently confidential. In addition to Haoyu Aerospace, this fuel has also been used in other spacecrafts and is said to have been used in missiles. Of course, these are just speculations. The biggest advantage of this kind of propulsion fuel is that the thrust generated by the fuel is more than 30% higher than that of traditional fuel, and this is only public data. We don't know the specific amount.

Continuing from the previous article: This semi-solid foamed propulsion fuel not only produces higher thrust than traditional fuels through combustion, but its biggest advantage is that it can be filled in advance and stored for a long time without causing corrosion to the tank. This kind of fuel is usually stored in a viscous liquid. When the fuel is decatalyzed, it will quickly foam and expand, and then injected into the engine to start violent combustion, thereby generating greater thrust.

Worship the elder, it’s too detailed. Is the elder working in the aerospace system or Haoyu Aerospace?

No, I am a college student majoring in aerospace and have not graduated yet.

No wonder it is so detailed. Where does Da Lao want to go after graduation? Haoyu Aerospace or the aerospace system.

Probably go to Haoyu Aerospace, if you can get in. I heard from my brothers and sisters that the salary and benefits offered there are quite high, but the requirements are also extremely strict. I don’t know if I can get in. If you can't get in, you might go to the aerospace system.

May your dream come true.

Let me go, this rocket looks big. It is indeed the largest launch vehicle in China at this size.

It is one of the largest launch vehicles in the world, but of course it is still not as good as the previous giants.

This Jianmu-9 is really the same as the Falcon Heavy rocket, and may be a little smaller than the Falcon Heavy rocket.

They're all pretty much the same, no one is necessarily worse than the other. And compared with Falcon rockets, Jianmu series rockets use new propulsion fuel and have a higher thrust-to-weight ratio.

With a multi-ton thrust, it can indeed kill most opponents in the world in an instant, and it can rank among the forefront of the world's heavy-lift rockets.

Strictly speaking, this Jianmu-9 should not be counted as a heavy rocket, but only a medium rocket. Medium-sized rockets should refer to large rockets with a transport capacity of more than 100 tons in low-Earth orbit.

There is no detailed classification of rocket classification, so both Jianmu-9 and Falcon Heavy rockets can be called heavy-duty launch vehicles.

Compared to last time, I am more interested in the lunar cargo transportation system inside the fairing. I heard that this time it also carried two small satellites for lunar survey, imaging and communication.

I am also very interested in this lunar cargo transportation system. I heard that this is a cargo spacecraft specially designed to transport cargo to the moon. The entire spacecraft is divided into two parts, the orbiter and the lander. The lander is the main part, which stores cargo and material equipment, while the orbiter is the small column section at the back, which is mainly responsible for promoting the entire lunar cargo transportation system, and for It provides electricity.

I heard that the ten tons of cargo transported this time included two multi-purpose engineering robots, an intelligent control robot, a lunar soil 3D printer, a large data antenna system, a set of solar panels, and a set of super Solid-state batteries, as well as a range of other materials.

It seems that Wu Hao really plans to build a city on the moon, which will directly send the lunar soil 3D printer to the moon.

In fact, this lunar 3D printer is not uncommon, it also exists in reality. It is said that the quartz in the sand is sintered and melted into a liquid material, and the required shape is printed through the printing nozzle.

Of course it's different. Don't forget that the moon is a low-gravity vacuum environment. The temperature difference on the moon's surface is particularly large, so the requirements for these equipment are very strict.

[In view of the general environment,

Compared to this lunar soil 3D printer, I am more interested in that intelligent control robot. Is this the stupid one in the movie "The Wandering Earth"?

Don't tell me, it does look a bit like it. In other words, this intelligent control robot was designed by our technical team based on the prototype of Benben in the movie.

Boy, the tech from the movie is finally coming to life.

Stupid? Stupid! Love it, love it! I’m really looking forward to its performance on the moon.

There is definitely a certain gap between reality and science fiction movies. However, I believe that given Haoyu Technology’s strong capabilities in artificial intelligence and robotics, this stupid person may not be as smart or intelligent as in the movie.
