"Mr. Wu, we deserve your continued commitment to the development of civil aerospace technology. From commercial launch vehicles to this new type of experimental spacecraft. Now many of us are more concerned and ask when you can send us ordinary tourists. Go to space and go on space tourism. Many people ask whether the price of space tourism can be lowered, and not just to become an exclusive project for the top rich."

Su Qian asked Wu Hao.

Wu Hao put down the coffee in his hand and said with a smile: "This is also the goal we have been striving for. It is the hope that more tourists can be sent to the sky to experience a wonderful space journey.

But it’s not easy to achieve this goal. Apart from other things, first of all, we must have a manned spacecraft that can send people into space smoothly.

Everyone knows that manned spacecraft is a very ambitious and complex systematic project. Let alone companies, it is difficult for most companies to support such a huge project.

So at present, there are only a handful of countries in the world that can play manned spacecraft, and only the few that are well known.

Although there are related successful cases, some companies and more than one company have developed manned spacecraft.

But these companies without exception have invested huge funds, resources, manpower and material resources, and time to achieve such results.

So if we want to build a manned spacecraft, we must invest a lot of manpower, material resources and time. This will be a huge number, which is very unbearable for us.

Therefore, if we really want to engage in manned spacecraft research and development projects, we must not rely on ourselves alone. We need to invite more companies to join us. We all work together so that this can be achieved.

In fact, it is technically, which can be combined with cost.

First of all, manned spacecraft technology can be said to be a combination of cutting-edge technologies that are currently integrated by mankind. There are only a few countries that can develop manned spacecraft. There are only a few to count, and technology is highly monopolized.

If we want to do it, what we will face is a project that most countries in the world cannot do. You can imagine how difficult it is.

Of course, this is not only reflected in technology, but also in research and development costs. To put it bluntly, most countries on the earth cannot support such a huge money burning project. "

Having said that, Wu Hao glanced at Susie, and then continued to preach: "Traditional manned spacecraft can only carry three to four astronauts at a time, and the space shuttle, as well as the current new generation The number of people is very high, but the number has been expanded to seven to eight people, almost doubled.

But despite this, the current carrying efficiency of these people is too low, and the price when converted into one passenger is very expensive. Except for those who are particularly wealthy, ordinary people, even those with substantial wealth, can hardly afford it.

So if we want more people to take a space trip at a reasonable price, then we have to reduce the price of each spaceship ticket.

If you want to lower the price, you have to lower the transportation cost per passenger. If you want to reduce costs, you must first reduce the cost of rocket launch and transportation.

We can use recyclable and reusable launch vehicles, which can greatly reduce the cost of rocket transportation.

So next, it is on the manned spacecraft. The current carrying capacity of people is too poor. If you want to be commercialized and want to reduce costs, you need to expand the capacity of people.

It will at least double, or even more, the current maximum crew of seven people. Generally speaking, it is more appropriate to control the crew within the range of 14 to 21 people.

In this way, we will be able to share the expenses originally shared among seven passengers evenly among 21 passengers, so that the transportation cost of a single person will be greatly reduced.

Secondly, it is to reduce the cost of manufacturing and using the spacecraft. There are two paths in this respect, just like our commercial launch vehicle.

Or use ultra-low-cost disposable spacecraft, which will reduce the cost a lot. The ultra-low cost I am talking about here does not mean to sacrifice the safety and reliability of the spacecraft. It is on this basis to reduce unnecessary things on the spacecraft, thereby further reducing costs.

The second method is the same as our Jianmu 2 retractable launch vehicle, which can be recycled and reused, which can also reduce costs.

If all of these can be achieved smoothly, we are sure to control the cost of each passenger within two million yuan, so that more tourists with space dreams can realize their dreams and take a trip to space dreams. "

"Two million yuan, the price is still too high, I am afraid that most people will find it difficult to bear. If nothing else, just say I, although I also have a strong dream of space, but I don't have two million for a space trip. Susie shook her head with a wry smile.

Ha ha ha ha, Wu Hao smiled and shrugged his shoulders: "Unless we have a huge overflight in space technology ~www.readwn.com~, the cost of going to space cannot be reduced to the point where everyone can accept it.

Just like intercontinental flights, aircraft technology has been developed for nearly a hundred years. Now, not everyone on earth can afford an intercontinental flight ticket.

The same is true for space travel. What we can do is to reduce this dream from being out of reach of most people and inaccessible in a lifetime to a lot of people's hard work, which can still be realized in this lifetime.

This is the limit that can be achieved according to our current social technology level. "

Susie nodded when she heard Wu Hao's words. Indeed, what Wu Hao said is not wrong. The price of two million can be said to be very conscientious. You know, the world's first space traveler, in order to be able to go to space, but spent 20 million US dollars.

And Wu Hao's quotation was only two million, less than one-tenth of that quotation, and it was still RMB, not U.S. dollars. It can be said that it is already very cheap, so you can't ask for too much.

Hearing his answer, Susie nodded, and then said to him: "In your words just now, you mentioned a sentence, unless we make a huge breakthrough in the field of space technology, the cost of going to space cannot be reduced to everyone. All are acceptable.

What do you mean by technological breakthroughs, similar to the space elevator in the science fiction novel "Three-Body"? "

Hearing Susie's words, Wu Hao smiled and shook his head again and again.

"The book "Three-Body" is very good, and I am also a loyal fan of it. However, we want to realize the sky elevator in the three-body, conservatively, I am afraid that it will not be possible in nearly a hundred years."
