The latest website: According to Wu Hao's request, Yu Chengwu quickly asked people to screen and edit some video surveillance and some shooting videos of this launch experiment, as well as some recorded materials in the previous research and development process, and finally cut them into a 13-minute section video documentary.

This 13-minute video documentary was immediately posted on the company's official website and official blog.

And because Wu Hao and Haoyu Technology Company have always been concerned by many netizens and media, but there is no movement of him recently. So once this video was released, it was reprinted and reported by many media, and it once again made the headlines of many media.

In the video, the research and development process of the two rockets is first recorded, and then the two rockets are transported to the launch center in the northwest desert, where the environment is harsh and the living conditions are relatively difficult, etc.

Below is the scene where Wu Hao and Zhang Jun came to condolences and watched the live launch.

Then there is a picture of two rockets launching at once, and the recording footage of the second return rocket landing and landing failure.

Finally, there is Wu Hao's speech. I don't know who used the mobile phone to shoot it. The picture is very shaking, but the voice is very clear.

Even at the end, there was such a sentence, our journey is the sea of ​​stars.

I have to say that the editor who edited and produced the film is a master. He expressed the joy of everyone when the rocket was launched, and the deep feelings of frustration and collapse after the failure. Coupled with the exciting background music when Wu Hao gave an encouraging speech at the end, the whole film quickly moved many people on the Internet.

Just when many people liked this wonderful video one after another, the content and information expressed in this video quickly attracted people's attention.

Although there were media reports a long time ago, Haoyu Technology acquired two young rocket research and development teams. After the news was reported, it didn't attract much attention, and it was quickly lost in the massive amount of information.

But this time, Wu Hao and the others directly showed the results. Although not too successful, it has already taken shape.

In particular, the two rocket technologies in the video have become the focus of discussion among many technology and aerospace enthusiasts and experts.

The first is a low-cost one-time rocket using 3D printing technology and materials. According to the introduction in the short film, 80% of the rocket is printed using 3D printing technology. This will greatly reduce the difficulty of rocket manufacturing,

Shorten the manufacturing cycle and greatly reduce the manufacturing cost.

In the words of Yu Chengwu in the short film, they are confident that they will reduce the price of launching satellites into low-Earth orbit to less than US$10,000 per kilogram.

This price can be said to be very ideal. After conversion, it is about 60,000 to 70,000 per kilogram on average. Based on the average weight of 20 kilograms of the more popular small satellites, the launch price of a satellite may only be more than one million yuan.

This price can be said to be very cheap, almost reaching the price of cabbage. In other words, as long as you want, you can send a satellite into the sky for one or two million dollars.

In this regard, experts are very interested in this low-cost rocket developed using new materials and new manufacturing technologies, and have given high praise.

In the words of an aerospace technical expert, this low-cost rocket is very competitive in the market. Moreover, private enterprises are more flexible to participate in such projects, can keep abreast of the market, do not have to be restricted by certain rules, and can avoid some troubles.

In the words of this expert, because it is a private company, it can show its unique advantages in some international projects. On the one hand, this purely commercial launch cooperation project can reduce the sensitivity of this project as much as possible, and will not be over-interpreted by the outside world.

On the other hand, it is the convenience of business cooperation, and the scope of confidentiality involved is relatively small, so it is more suitable for cooperation with these international customers.

Of course, some experts have expressed concern about this, and believe that it is inappropriate for private enterprises to enter such sensitive fields. It is hoped that the relevant departments can strengthen the management in this area, and formulate relevant management restriction laws and regulations as soon as possible.

For example, this expert said that the reliability and safety of private rockets cannot be guaranteed, and major accidents are prone to occur. Now that the domestic airspace is relatively dense and there are many flights to and fro, if the rocket hits the plane, it will be a big event.

One is that the falling of rocket wreckage may pose a threat to the personal safety of residents in the area, and it will also affect the production and life of the people in the area.

As soon as the expert's words came out, many people immediately agreed with them and began to oppose them. Some people even @ the relevant departments and various departments, hoping that they can come forward to express their views.

The so-called big tree attracts the wind, and this may be the case. In the past, there were many cases of private rocket launch experiments, but we have never seen such a big reaction. Wu Hao and the others popped up as soon as they did this.

The expert's words are actually correct, he just expressed his concerns about this aspect. However, his words were misinterpreted and used, resulting in so many rhythms.

As a last resort, the company's official blog can only respond. Clarified the reason for the whole thing, and explained the experiment that happened this time. All launch experiments have been approved by relevant departments and full preparations have been made. There were no unsafe accidents in this experiment, and no one or personal property was injured.

As for the second retractable rocket, everyone has discussed it more technically. The first thing to discuss is whether the technology used by Wu Hao and the others is reliable. It is not that the plan of using a parachute to recover and land has not been mentioned, but no one has practiced it until now.

So this also makes many people question their recycling technology. On the one hand, they question whether this technology is reliable. After all, this recycling test has failed.

Another group of people questioned that this technology is backward after all, far from the advanced technology of the Falcon rocket, and they also questioned whether it can reduce costs.

Not only that, but it was discussed by experts and even featured on some spotlight shows.

Some experts said that this technology is relatively backward, it is completely outdated technology, and there is no room for operation.

Another expert objected to this, saying that it is not important that technology is outdated, but how to reduce launch costs is important. Judging from the content disclosed so far, this technology can still greatly reduce the launch cost, which is very suitable for commercial space launch missions.

Compared with the experts, the discussion among the public was more intense, and even split into two opposing factions, which made the debate extremely enjoyable.
