On May 9, the five crew members of the Steadfast made their official appearance in Qiongzhou, and their outfits were a huge change from before.

The nature of the three others, including Commander Hu Dong, Chen Jun and the others, was informal, and this was China's first manned space orbital flight for purely commercial purposes.

For the first time in the world, but with one more premise: private companies are dominant.

Originally, it was widely believed that Musk might compete for the first place in the private company's commercial space delivery into orbit because of the Dragon spacecraft, but now this name belongs to Xinyuan Aerospace Power.

The two coal bosses and the writer are too old, and after more than 6 months of vocational training, of course, in order to be worthy of the 50 million training fees they paid, they have experienced all the projects, and the ground weightlessness experience market has been several hours.

Chen Jun was different, he only got a place before the Spring Festival, went to training at the end of March, and completed all the training on May 4.

One is that he is in his forties, younger than the three old men, and his physical condition is much better, but it is only measured by the load standard, in fact, an ordinary person with good physical fitness is theoretically fine even if he does not train.

The rich practice more is just to be worthy of their status and charge more money, and most of these rich people are too old to reduce the hidden danger of disease first.

For example, Ke Yun, a system engineer, because he has obtained the senior student certification in the flight school, only conducted a closed training camp for 1 week, and then sent it to space.

The crew of the first commercial manned flight in China in the five countries even had different clothes, many logos were removed, and the appearance was as simple as possible.

This is also to distinguish between commercial and official missions, and to make space as close as possible to life.

While the four passengers were being interviewed and concerned, Guo Shen met with Masashi Okada.

"Do you want to join Xinyuan? But your identity is the problem, you can't work in China on a tourist visa, and we don't lack engineers. ”

Guo Shen was very surprised by Okada Kuangshi's intention, this sneaky old book close to the B-level base would have been detained by the Security Department if he hadn't identified himself in time, and then he asked to see the executives of Xinyuan Company, and since Lin Ju was currently in the capital, Guo Shen met him.

But as soon as Okada exited, he wanted to join Xinyuan Company, and it didn't seem to be a joke:

"Guo Sang, I know that your company's status in China is different, I really want to continue to develop in your country, the island country's aerospace has been locked, from H1 to H3 rockets actually have no progress, it is just a toy for the people to look like.

I think Xinyuan is the place where we Asians surpass rice animals in space, and I have brought a lot of technologies for H series rockets, hydrogen and oxygen engines, solid rockets, electronic engines, and space measurement and control, which can prove my loyalty! ”

Okada's self-taught Chinese is very good, Guo Shen looked at the USB flash drive he took out, touched his chin and thought.

Technology, of course, is insignificant.

Before the official start of manufacturing of Xinyuan 3, JAXA's LE-9 expansion cycle hydrogen-oxygen engine was really the first in Asia, but now the first Xinyuan 3 is going off the assembly line, and the 240-ton staged combustion cycle hydrogen-oxygen engine used in the second stage has been used many times, who can still look at LE-9?

There is also a solid rocket, the S-700 single-stage thrust of 700 tons, which is a black technology that vigorously flies bricks all over the world, but it is too expensive to leave the Xinyuan-4 rocket with no manufacturing.

But how to say it, if the things in the USB flash drive are true, then Okada is really ruthless enough, and he has moved all the little technical essence of JAXA over, and the kind that doesn't leave any bottoms.

It's done so badly, Okada Yasei really wants to join.

Betraying JAXA, does Xinyuan already have such a strong appeal?

However, the issue of Okada's identity will cause unnecessary disputes in the international community, so should we accept his refuge?

Guo Shen chose to leave the problem to his boss.

In the capital, Lin Ju is fighting with Androv in the Aviation Development Commission.

The space agency plans to carry out another Chang'e-5 mission next year to carry out unmanned sample returns.

This mission has two purposes, one is to increase the familiarity with the lunar surface again, obtain more data, and if it is still launched by Xinyuan-5B, it will not cost too much money, and the Fifth Academy will also have the energy to design a probe.

At present, the main tasks of the Fifth Academy are still very important, one is the two subsequent test chambers and a space telescope of the Tiangong space station, but the lander for manned landing on the lunar surface, as well as the lunar surface scientific research station.

It seems to be a lot, but now that the five hospitals have expanded their staff, they can fully cope with it.

Therefore, the second purpose of Chang'e-5 is to verify the rendezvous and docking technology in lunar orbit.

The process of unmanned sampling return is the same as that of manned return, the lander is separated, landed, sampled, the ascender takes off into orbit, rendezvous and docking, and returns.

Except for the size, there is no difference from a manned mission to the moon, and doing a mission will be reassuring.

Therefore, the Aviation Development Commission discussed this project internally, and the space agency also liked to use the way of cooperation between the Aviation Development Commission and private enterprises.

Of course, another reason is that only the rocket of Xinyuan Aerospace Power can complete this task now, and the capacity of Xinyuan 5B is just enough, and the overall mass of Chang'e 5 should be controlled at 7980 kg, which can be done.

Xinyuan Aerospace can provide cheap rockets, and by the way, it can also expand the payload mass, and other private enterprises can also save some energy and resources by participating in it, and can complete more tasks without increasing or even reducing government spending.

But Xinyuan raised objections to the Chang'e-5 mission.

Anderov thinks that in the case of manned lunar exploration, unmanned sample return is simply a waste of resources, the manned returner can bring back 100 kilograms at a time with such a large mass, can the unmanned returner have 10% of this?

Of course not, Chang'e-5 is expected to bring back no more than 2 kilograms of lunar soil, and astronauts will go up and shovel more than that.

Anderov thinks that Chang'e-5 can be changed and sent to a mobile nuclear power vehicle.

It is to make a reactor into a lunar rover, which can provide electricity for future lunar research stations, such as charging a lunar rover or a living module.

This mobile nuclear power plant weighs about 3.4 tons, generates 38KW of electricity, can operate continuously for 15 years without maintenance, and can rely on wheels to move on the lunar surface, follow the march, and is also very helpful for lunar surface exploration.

In the future, Xinyuan-2A will launch a larger stationary fission power station with a landing mass of 23 tons to the lunar surface, with a power generation of an astonishing 2,000KW, and will use the moon's dry ice and water resources to synthesize methane and liquid oxygen to build a fuel supply station.

In fact, this stationary nuclear power plant can reach 3000KW, but the nuclear power plant needs to dissipate heat, and vacuum is the enemy of heat dissipation, so it has to use nearly 4 tons of mass to manufacture a complex heat dissipation system, which is designed to replace the fuel once every 20 years.

It's much easier to do on Mars, even if the Martian atmosphere is very thin, the heat dissipation problem is much easier than vacuum.

The nuclear power train can be completed next year, and the stationary nuclear power plant will have to wait for 2018, so instead of launching a useless Chang'e-5, it is better to make a little preparation for the lunar base first.
