Selling things is all about publicity, and many people like to exaggerate the publicity a little bit when selling things, just to sell more, and then make more money.

These are relatively normal operations, as long as you don't exaggerate too much, generally no one will look for trouble.

Even sometimes there are competitors, so when you advertise yourself, you exaggerate your strengths, and then exaggerate the shortcomings of your opponents, which is a competitive process.

Whoever survives counts.

However, the approach of the new ISS is a bit of nonsense.

Even though he was promoting his own merits, many other people were watching it.

Generally speaking, if it is a modular structure, it is indeed conducive to replacement, which is also the trend of development now, that is, for convenience and speed, even if there is a place damaged, just remove it and replace it with a new one, and even some general things, even find professionals do not need to be.

From this point of view, the new ISS has done a good job in this regard, and it is fully prepared for future development.

Although the Tiangong space station was not mentioned in the promotion of the new ISS, the discerning people could see at a glance that they had secretly compared many rounds.

Moreover, these contests are still the initiative of several partner countries of the new International Space Station, and the Arc Group does not pay attention to them at all, what should they do.

Because in the eyes of Arc Group and Dong Chen, this is not comparable to the original, they haven't even built it yet, even if there is competition, it will be after the completion of the new International Space Station.

However, the new ISS partner countries are better than theirs, and some people also know some general situations, that is, the new ISS model is a relatively intuitive modular design at this stage, and it is also the best formation model that the earth countries can come up with at this stage.

The Tiangong space station is another model, it is a design that is more inclined to the future, or it should appear in the space station in the next tens of hundreds of years, its overall stability is more stable, and the protection ability is stronger.

Relatively, the new International Space Station is more convenient in this mode, and it looks huge, but its internal space is definitely less than 70% of the Tiangong space station that is smaller than it, and its protection is not good, and the protection against space junk is no different from that of ordinary space stations.

Besides, the Tiangong space station is not without a module structure, but its module architecture is not so obvious, at least there is no cabin connection like the new International Space Station...... So obvious.

It's the same as building blocks, everyone knows that it belongs to the category of modularity, and it is the kind of very simple modular meaning.

In one respect, there is nothing wrong with the advantages advertised by a few partner countries.

And then there's the truck that was in charge of transporting the goods this time...... Cargo Arrow, the latest "Space Launch System" of the United States, is a super-heavy launch vehicle evolved from the Space Shuttle, designed by the National Space Administration of the United States, the main purpose of which is to maintain the progress of the constellation program and replace the space shuttle that has been decommissioned.

The first phase of the project will focus on manned missions of 70 to 110 tons, followed by a 130-ton cargo bay load mission.

Eventually, it will be designed to carry 143 tons, and possibly even 165 tons.

On the whole, the Space Launch System is still very similar to the Saturn V, both are super-heavy launch vehicles, both are surprisingly large in size, and the missions performed are also the most difficult missions.

However, after so many decades, it is much more advanced than the Saturn V, and the capacity once again surpassed the Long March 9 launch vehicle used by Huaguo to land on the moon last time, and it can be said that it is the strongest launch vehicle system in history so far.

Coupled with the fact that rocket recovery technology has become more and more pure, it can be reused many times, so that it can be used much more effectively than the previous space shuttles, and it is also much cheaper than the Saturn V.

This also achieves the purpose for which it was developed, being more reliable than the Space Shuttle and cheaper than the Saturn V.

You must know that the rocket is much more mature than the space shuttle, and it is currently the most reliable space tool for mankind, and the cost of Saturn V is not to be said, the cost at that time was equivalent to a nuclear-powered aircraft carrier.

Think about it, a launch of the Saturn V is a nuclear-powered aircraft carrier flying in the sky, and it is still a one-off, there is nothing very necessary for a big event, who would do this.

Saturn No. 5 is directly called "Tuhao (No.)" or "Trench", and only Tuhao can play, and it is still painful to play.

Speaking of the problem of reliability, it was because of the two disasters of the space shuttle in the United States that the space agency of the United States needed to develop a more reliable transportation system.

Because after their analysis, if an ordinary series-parallel hybrid rocket launch system was adopted, both disasters could have been avoided.

The first space shuttle disaster arose due to the fact that the booster was damaged during the launch, and the personnel could not escape.

Because once the booster of the space shuttle is activated, the astronauts will not be able to escape, and there is no emergency escape pod on it, and it would be doomed to parachute like a normal airplane.

And if an ordinary rocket was used at that time, then this manned space mission would definitely be equipped with an escape tower, which is the "lightning rod" on the rocket. In the event of an accident, the astronauts can activate the escape tower to escape.

The second space shuttle accident was caused by damage to the wings, which were destroyed during the descent, which had a chain reaction and the final accident.

If you use an ordinary spaceship, that is, the manned return capsule of the rocket, a conical cabin with a smooth appearance, there is no possibility of damage to the wings of this thing at all, and it will come down directly, and it will be good to open the parachute at a predetermined altitude.

The United States has set high specifications for the "Space Launch System", saying that it can transport astronauts to greater distances and is the cornerstone of human space exploration.

Its appearance will open a new era of human exploration of space, when the "Space Launch System" will send the astronauts on board the "Orion" spacecraft into space, the first destination is an asteroid, and the final destination is Mars, which can be said to be the farthest place to go in manned spaceflight.

However, after the sudden emergence of arc aerospace, looking at the aerospace equipment developed by arc aerospace, what "cornerstone" and "new era" are used on it, it is no longer very consistent.

No matter how much they advertise this, there are not many people who believe it, after all, there is an arc space flight spaceplane there, even if they say that this "space launch system" was born for the Mars mission, which is about to make the United States the first country to land on Mars.

And in Dong Chen on Arclight Island, he watched the news while eating, and he also judged his head while watching.

I have to say that the United States should spend a lot of public relations and publicity expenses this time, and the news about the new International Space Station can be said to be overwhelming, mainly to promote how big its volume is, what are the benefits of the modular design of building blocks, there are some modeling drawings inside the space station, but there is no mention of how big the internal space is.

"You said that this rice country will be launched if it wants to be launched, what's the use of saying so much, don't you know what it means to "say less and do more"? Actions are the most convincing. And they are all talking about the advantages and disadvantages, and they are all talking about the advantages, not saying any of the disadvantages, and they are misleading those who do not know. Dong Chen said to No. 1 sitting next to him while stuffing rice into his mouth.

No. 1 looked at Dong Chen and said with a smile, "Sir, of course people have to think about themselves, and show their strengths and not their weaknesses, isn't this the common nature of all creatures?" ”
