Chapter 598 The belated “star”

Selling things requires publicity, and many people like to exaggerate a little when selling things, just to sell more points and make more money.

These are relatively normal operations. As long as you don't exaggerate too much, usually no one will cause trouble.

Even sometimes there are competitors, so when promoting yourself, you exaggerate your own advantages, and then exaggerate the opponent's shortcomings. This is a competitive process.

Whoever survives is the winner.

However, this approach of the new International Space Station is a bit nonsense.

Although he is promoting his own advantages, many others are also watching.

Generally speaking, if it is a modular structure, it is indeed conducive to replacement. This is also the current development trend. It is for convenience and speed. Even if one part is damaged, just remove it and replace it with a new one. Even some ordinary Stuff, you don’t even need to call a professional.

From this point of view, the new International Space Station has indeed done a good job and has made full preparations for future development.

Although the Tiangong Space Station was not mentioned in the promotion of the new International Space Station, anyone with a discerning eye could tell at a glance that they had secretly compared it for many rounds.

Moreover, these contests were initiated by several cooperating countries of the new International Space Station. Arclight Group ignored them at all and did whatever they were supposed to do.

Because from the perspective of Arclight Group and Dong Chen, there is no comparison with this. They haven't even built it yet. Even if there is competition, it will only happen after the new International Space Station is completed.

However, the cooperating countries of the new International Space Station are better than theirs. Some people also know some general conditions, that is, the new International Space Station model is a relatively intuitive modular design at this stage, and it is also the best that the countries on earth can come up with at this stage. Good build model.

The Tiangong Space Station is another model. It is a design that is more inclined to the future, or it is a space station that should appear tens or hundreds of years in the future. Its overall stability is more stable and its protective capabilities are better. powerful.

In contrast, the new International Space Station is more trouble-free and looks huge, but its internal space is definitely less than 70% of the smaller Tiangong Space Station, and its protection is not good against space debris. It is no different from an ordinary space station. If you encounter a relatively large piece of space junk, you still have to start the engine to avoid it, otherwise it will definitely follow the footsteps of its predecessors.

Besides, it’s not that the Tiangong Space Station doesn’t have a modular structure, it’s just that its modular structure is not that obvious. At least it’s not as obvious as the new International Space Station where modules are connected one module at a time.

It is just like building blocks. Everyone knows that it belongs to the category of modularity, and it has a very simple meaning of modularity.

In one respect, there is nothing wrong with the advantages promoted by several partner countries.

And there is the truck responsible for transporting cargo this time... Cargo Rocket, the latest "space launch system" of the United States. It is a super-heavy launch vehicle evolved from the space shuttle. It was designed by the National Space Administration of the United States. Its main purpose is Maintain the Constellation program and replace the retired space shuttle.

Its first phase will focus on the 70- to 110-ton Constellation program manned missions, and will later develop 130-ton cargo-type payload missions.

Eventually, its design carrying capacity will be upgraded to 143 tons, and may even reach 165 tons.

Overall, the Space Launch System and the Saturn V are very similar. They are both super-heavy launch vehicles, surprisingly large in size, and perform the most difficult tasks.

However, after so many decades, it is much more advanced than the Saturn V, and its transportation capacity has once again surpassed the Long March 9 launch vehicle used by China to land on the moon last time. It can be said to be the most powerful launch vehicle system in history so far. It’s not an exaggeration.

Coupled with the increasingly pure rocket recycling technology, it can be reused many times. In this way, its role is greater than that of the previous space shuttle, and it is also much cheaper than the Saturn V.

This has achieved its development purpose, being more reliable than the space shuttle and cheaper than the Saturn V.

You must know that rocket technology is much more mature than the space shuttle. It is currently the most reliable aerospace tool for mankind, and the cost of the Saturn V is nothing to say. At the time, the cost was equivalent to a nuclear-powered aircraft carrier.

Think about it, launching the Saturn V once is a nuclear-powered aircraft carrier flying in the sky, and it is a one-time event. There is no very necessary event. Who would do this?

It's okay to just call the Saturn V "Tuhao (number)" or "Hao". Only the local tycoons can afford it, and it's still painful to play.

Let’s talk about the issue of reliability. It was because the American space shuttle had two disasters that the American Space Agency needed to develop a more reliable transportation system.

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

The first shuttle disaster occurred when a booster was damaged during launch and personnel were unable to escape.

Because once the space shuttle's booster is activated, the astronauts cannot escape. There is no emergency escape cabin on it. If you want to parachute like an ordinary airplane, it is even more difficult.

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

The second space shuttle accident occurred because the wing was damaged and was destroyed during descent, which then caused a chain reaction and led to the final accident.

If an ordinary spacecraft is used, that is, the rocket's manned return capsule, a conical capsule with a smooth appearance, there is no possibility of wing damage on this thing. It will come down directly and open the parachute when it reaches the predetermined height. alright.

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

Its emergence will usher in a new era of human exploration of space. At that time, the "Space Launch System" will send the "Orion" spacecraft carrying astronauts into space. The first destination is an asteroid and the final destination is Mars. , can be said to be the farthest place that manned spaceflight has traveled.

However, after the sudden rise of Arc Light Aerospace, looking at the aerospace equipment developed by Arc Light Aerospace, the "cornerstone" and "new era" used in it are no longer consistent.

No matter how much they promote it, not many people believe it. After all, there are arclight space planes there. Even if they say that this "space launch system" was born for the Mars mission, it will soon make the United States the first A country that goes to Mars.

As for Dong Chen on Arc Light Island, he was eating, watching the news, and commenting on it.

I have to say that the United States should have spent a lot of public relations and publicity fees this time. The news about the new International Space Station has been overwhelming. They are mainly promoting its size and modular modular design. The good thing is that there are some modeling drawings of the interior of the space station, but there is no mention of how big the internal space is.

"You said that if the United States wants to launch, just launch it. What's the use of talking so much? Don't you know what "less talk, more action" means? Practical actions are the most convincing. And they are all talking about the advantages, and there are no disadvantages. He said that he made a good calculation and misled those who were unaware." 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 should consider themselves, and show their advantages and not show their disadvantages. Isn't this a common trait of all living things?"
