Of course, the upper stage is only used for special needs such as multiple satellites with one stone, high orbit and precise orbit entry. In general, there is no need for a propulsion unit at the upper stage.

After all, the upper level also costs money, and it costs a lot of money.

In fact, the approach proposed by these experts is actually highly questioned and controversial.

After all, whether it is the first-stage rocket body or the second-stage rocket body of the rocket, even in the case of running out of fuel, the weight of the empty arrow body is very medium, and the acceleration of the arrow body falling from a high altitude, even if there is a paraglider, but such a large acceleration, even if it is captured by a heavy helicopter, it may be difficult to lift it.

As for the combination of multiple heavy helicopters for recycling and retrieval work, the coordination of multiple helicopters is also a problem.

Even the combination of multiple heavy helicopters in such close proximity for recovery and retrieval missions is fraught with many uncertainties and dangers.

As for the fairing, it is relatively light, plus there is a paraglider to slow down, and the speed is relatively slow, which is also suitable for helicopters to capture in the air.

The successful completion of these two launches and recovery marks that Haoyu Aerospace has become the second private company in the world to master the recovery technology of the rocket first-stage rocket body and fairing.

And from the cost point of view, Haoyu Aerospace's Jianmu-2 rocket has a cost competitive advantage.

However, even this kind of commercial space program has its own peculiarities and complexities, and not all orders can be accepted.

Of course, domestic commercial space launch orders only need to be approved by the relevant departments, which is naturally no problem. However, the issues involved in foreign commercial space launch mission orders are more complicated.

First of all, because of some well-known reasons, as well as the comprehensive suppression of Europe and the United States in this regard, this also makes it difficult for them to obtain commercial satellite launch orders from many countries in Europe and the United States, even if they are private enterprises and carry out commercial space launch missions.

Therefore, their overseas launch orders are generally from some developing countries, or even underdeveloped countries. And in this regard, it is difficult for them to compete with the national team.

So there is still very little room for them to develop, but it is not impossible. For example, they successfully won an order to launch a small communications satellite in an African country.

Of course, at present, the domestic aerospace field is developing rapidly, especially in the field of microsatellites, with the current launch price getting lower and lower, more and more enterprises and scientific research institutions are developing their own microsatellites.

So from this point of view, the development prospects in this field are also very broad.

In addition, Haoyu Aerospace will also launch its own related space payloads, including experimental spacecraft, satellites and so on.

With various media reports, these two launch missions have also attracted the attention of many people, and there are even many industry bigwigs and Wu Hao's old acquaintances.

For example, Brother Xiaoma, who personally visited the launch base of the Northwest R&D Center, called Wu Hao after the two launch and recovery missions.

Looking at the little brother Ma who was wearing a white shirt and sitting in a precarious position in the video, the corners of Wu Hao's mouth turned up slightly.

Brother Xiaoma, although he is relatively low-key, but his personality is not bad, whether it is in the world, he is very gentle and elegant, which makes people have a good impression.

Since they met Brother Xiaoma, the two have also had a lot of anxiety, and sometimes they will call or message each other to greet each other, and the relationship has gradually become familiar.

Xiao Wu, congratulations. The two launches were not only a complete success, but also quite successful. I didn't expect you to achieve such results in just such a long time, which is really remarkable.

Hehe, thank you. Wu Hao thanked with a smile.

Brother Xiao Ma laughed in the video: "How did you come up with this recycling method, it's really whimsical and amazing." ”

"This kind of charging method is not the first thing we came up with, this is actually someone came up with it, but we have made relevant improvements and optimizations on this basis, and this time the experiment was successful." Wu Hao explained with a smile.

I'm curious to see how much money this fairing will leave you with if it is successfully recycled, and how much the whole recovery will cost. Brother Pony then asked him what he was more concerned about.

Wu Hao smiled when he heard this question. In fact, many people have asked him this question, so Wu Hao replied directly with a smile: "The whole fairing is divided into two halves, although it is only two halves of the protective shell, but it is actually relatively expensive, and the entire production and manufacturing will take about one or two million to transport to the launch site for assembly."

If it can be successfully recovered, it will leave us with almost more than 1 million launch costs.

As for the cost of recycling, it is relatively low, about 100,000 yuan. ”

Hearing Wu Hao's answer, Brother Xiao Ma nodded, and then said: "In this way, your first-stage rocket and fairing will add up to more than 80% of the rocket manufacturing cost." ”

Wu Hao waved his hand again and again when he heard this: "It can't reach that much, about 60 to 70 percent, and the cost of the second-stage rocket is still relatively high."

Of course, compared with traditional disposable rockets, the launch cost is naturally much lower, and the corresponding launch cost will be much cheaper. ”

"It's a great idea to save 60 or 70 percent. So what about this two-stage rocket, can it also be recycled? Little Pony then asked another question that he was interested in.

In this regard, Wu Hao shook his head: "There is no technology in this area at present, and it is too difficult to recover the second-stage rocket." In particular, it needs to pass through the atmosphere twice, and the friction and burning damage to the second-stage rocket body is relatively large, so it generally does not have the conditions for recovery.

And even if it can be recycled, it doesn't have a high recycling value. The manufacturing cost of the second-stage rocket body is almost half cheaper than the first-stage rocket body, and the recovery of the second-stage rocket is large and the cost is high, so it is basically not of much value when it is offset, and naturally there is no need for this. ”

Hearing Wu Hao's words, Brother Xiao Ma nodded, and then said to Wu Hao: "After returning from the launch site of your Northwest R&D Center last time, I am more proud than you."

I would also like to try to explore the field of space technology, but don't get me wrong, we have no plans to enter the field of space launch at the moment.

We have set up several spacecraft and micro-research laboratories that are currently working on an experimental data communication satellite for us, which we hope to launch on your rocket. ”
