In addition to Lucia's Yuri, Antoine and Badis, the two heads of the space agency from the country and Italy, also went to China in a low-key manner.

They had the same purpose as Yuri, and they were also heading for the moon and the space station.

The world's four major space agencies, ESA, NACA, Lucia Space Agency, and China Space Agency; Theoretically, the strength of the Chinese space agency is the weakest, and the combined technical force of the ESA is actually very strong.

The Lucia Space Agency has a technical foundation but no money, NACA is too miscellaneous and costs money to do everything, ESA has money and technology, but it is indeed the most chaotic.

There are so many countries in Europe, basically you are good at combustion chambers and I am good at turbopumps, it has a very strong design of the arrow body, and it has very good strength in a certain field, but it lacks all-round integration and cannot be closely united.

For example, Aramco's Artemis program is very different from the Apollo program half a century ago, and it is open to cooperation with 11 countries, including European countries.

But the problem is that the Artemis project is going to be in line, and everyone knows that the NACA pigeons are also far away, and they are counting on them to be out of play.

Although the Chinese space agency does not even have heavy rockets now, as the world's largest industrial power, steel production exceeds the second to twentieth combined, and the second largest economy, if they are really ruthless, they must go to the moon, and no one will doubt that they will not succeed.

What's even more outrageous is that Huaguo has even raised a private aerospace company side by side with major space agencies, and it also has the potential strength to carry out manned lunar landings, which is really enviable.

The two stayed in the capital with Yuri for a few days, and there was also a discussion within the Aviation Development Commission whether to accept them.

Of course, the space agency accepts it, not to mention that there are still a lot of unique technologies in the country and Italy, and the international significance of this matter alone must be sought, but the Tiangong space station is operated by the Aviation Development Commission, and the opinions of Xinyuan Aerospace Power are equally important, so the problem is thrown over.

Xinyuan's liaison agreed after being authorized by Lin Ju, and except for some necessary but understandable restrictions, he was almost a laissez-faire attitude towards the Tiangong space station.

The space agency was a little relieved and at the same time secretly wondered, why didn't Lin Ju care about such an important space station?

It wasn't until November 13 that the space agency launched the Shenzhou-11 spacecraft to the docked Yungong-Tiangong-2 combination that it learned a piece of news.

Xinyuan has sent a new round of orders to downstream companies, one of which belongs to the Eighth Academy of Aerospace Sciences, and it is inferred that they will be used in giant rockets with a diameter of at least 10 meters.

The big guy immediately looked for it on the official website of Xinyuan Company and quickly found the corresponding rocket.

It is the Xinyuan-3 giant rocket, the parameters set by this rocket have changed slightly, the layout of 11 meters in diameter and 19 K380s at the bottom has not changed, the thrust has increased from 7300 tons to 7500 tons, the take-off mass is 5900 tons, the low-earth orbit carrying capacity is 247 tons, and the lunar transfer orbit capacity is 101 tons.

It is lower than the previously announced capacity parameters, but it also means that this is no longer a PPT, but has entered the stage of substantive demonstration R&D and manufacturing, and it is really intended to be made!

"What the hell!"

The big guy was in the manned space office when he looked at the data, and Academician She, who happened to come here to revise the lunar research station plan, was also there.

Academician She probed over and learned that Xinyuan Aerospace was probably building the Xinyuan-3 giant rocket now, and the surprise on his face made an old face a little deformed.

"The CBC configuration of Xinyuan-2 is enough to land on the moon, and the reliability of their rocket is also good, why are they still working on giant rockets? This is more exaggerated than the Long March 9! ”

The Long March 9 is still the original old configuration, with two YF130s each of the four boosters and four YF130s in the core stage, with a total thrust of 5,700 tons and a designed low-earth orbit capacity of 150 tons, which is much stronger than the Saturn 5, and the result is that the Xinyuan 3 has been exaggerated to 7,500 tons of take-off thrust.

Academician She didn't doubt Xinyuan's technical strength, after all, this company is really outrageous like Kaihang, even if it is stolen from abroad, it can't be stolen, but why do they build such a powerful giant rocket? Landing on Mars?

Wait, it's possible!

The big guy saw that Academician She lowered his head and thought for a while, and suddenly his face was as uncomfortable as constipation, and he hurriedly asked what happened, and then he heard that Lin Ju might be preparing to land on Mars.

"Are you sure? Landing on Mars? I'm afraid it's not just enough rockets, right? ”

"The biggest problem with landing on Mars is the rocket, since the last century, countries have demonstrated that at least 300 tons of spacecraft are needed, but the Xinyuan-3 launch twice is enough, and the ten-meter diameter capsule can only be prepared for long-distance voyages, only such a large-volume spacecraft needs a giant rocket;

And isn't Xinyuan now carrying out a nuclear propulsion program? If you join the A100, the success rate is close to 99%, and you can't use it at all after only a few days on the moon. ”

"Sss

The big guy sucked off half of the cool air in one gulp, and the other half of Academician She had already sucked it away first, causing everyone else to feel a lot warmer.

He felt the seriousness of the situation again, and after a long time he said:

"Don't report this beforehand, damn it, we can't have an endless space race with a private company, right? This is just speculation, don't jump to conclusions. ”

Academician She: "But look at their attitude towards the space station, what could be more fascinating?" ”

"No, even if these subsystems are to be done, it will take more than three or four years, and there is a window limit for landing on Mars, at least when the moon landing program ends."

Academician She patted his head: "I forgot about this stubble, the next Mars exploration window is from May to June 2018, if you really go, you must send the unmanned probe over first, and then the next window period is 2020 and September 2022, no matter how radical you are, you will get seven years later, I am unfounded."

As long as it's not a landing on Mars, what could be more powerful than landing on the moon? ”

……

In the Fifth Academy, Li Xi, as the chief engineer of the Long March 5, announced one good news and two bad news to the team.

Bad news: Long March 5 program terminated, project cancelled;

Good news: the team will not be disbanded, and there will be an additional 3 billion yuan in funding;

The bad news: they are going to build a new rocket, which is more troublesome than the Long March 5.

However, what is surprising is that instead of the rocket of the private company Xinyuan Aerospace, the Long March 5 is replaced by the Long March 10.

The Long March 10 has a low earth orbit capacity of 110 tons, which seems to have nothing to do with the Chang 5, which is positioned at 30 tons of LEO capacity, but don't forget that the Long March 10 is bundled with four boosters.

After discussion, the First Academy dismantled two rockets, Long March 10A and Long March 10B:

Long March 10A: Reducing the four boosters to two, with a take-off thrust of 1,956 tons, a take-off mass of 1,500 tons, a LEO capacity of 70 tons, and a lunar transfer orbit capacity of 27 tons;

Long March 10B: Smooth pole type, no booster, only two YF130s of the core stage, with a take-off thrust of 978 tons, a take-off mass of 777 tons, and a LEO capacity of 24 tons.

The capacity of the Long March 10B and the Long March 5 is close to that of the Long March 5, so there is no need for the Long March 5 to exist, and it cannot be reused anyway, so it is better to reduce a project.

However, the team still had to continue to work, and gave Li Xi an important task to develop the new Long March 5.

The space agency required the new Long March 5 to use a 6-meter-diameter rocket body and plug seven YF135s to manufacture a reusable heavy-lift rocket with a take-off thrust of 2,600 tons, a take-off mass of 2,000 tons, and a low-earth orbit capacity of 60 tons.

The second-stage rocket engine will use a newly designed YF90, 220-ton staged combustion cycle hydrogen-oxygen engine, and the lunar orbit capacity can reach 24 tons.

At the same time, the CBC configuration of the new Long March 5 will be developed, initially named Long March 15, with 21 YF135s, take-off thrust of 7,812 tons, take-off mass of 5,780 tons, and the near-earth orbit capacity increased to 185 tons, and the lunar transfer orbit capacity of 74 tons, as the main force of the future cheap heavy rocket and subsequent lunar surface construction, it is required to make the first flight before 2020.

The Long March 15 of the Long 5 light pole type and the Long 5 CBC is enough to replace the Long March 10 series, which is strong enough and cheap enough.

You must know that the old Changwu project was established in 2009 and is expected to make its first flight in 2017, which lasted 8 years, and the more crazy new Changwu has not even had a shadow of the engine, so it is required to make its first flight in 5 years......

The YF135 is the successor to the YF130, which has been planned for a long time, with a single combustion chamber of 360 tons of thrust, which can just be used as an engine for future reusable giant rockets.

The superiors are really forced to increase investment, and the future of the space agency will be both happy and painful.

I'm a little busy today, and I don't have time to proofread the manuscript at night, so I sent it together~
