The take-off of the Yishan super rocket is not an exaggeration to describe it as "earth-shattering and crying ghosts and gods".

That huge wave of sound can travel far and wide!

That huge figure can be watched as it flies into the universe!

The huge tail flame also makes the infrared radar capture exceptionally clear!

Anyway, the Yishan rocket is directly related to the word "huge", and no one doubts the name of "Yishan" anymore.

Some people even feel: "It's nothing to move the mountain without moving the mountain, and if the mountain is blown up directly, there is no problem at all, and the effect is the same." ”

The moat becomes a thoroughfare!

Gravity and the atmosphere are the "moat" between human beings and space, and the "natural formation of a ditch that hinders traffic" for human beings to move towards the future.

Tianxia people are very familiar with this, the geographical environment of Tianxia is too complicated, people live in Tiannan and Haibei, so Tianxia people build bridges, pave roads, pass ditches, move mountains, reclaim the sea, and pass tunnels, and connect the whole "world" together.

The same is true now, when the Yishan rocket was launched, it is a "cable-stayed bridge" in the space age, helping mankind to communicate between the ground and space.

"Booster separation!"

The Yishan rocket has already flown very high, although the infrared tracking can be seen clearly, but that picture is no longer very friendly to the audience, so what the audience is shown is the rocket perspective.

When the booster separated, the audience could see that the originally tightly fitting butt suddenly split a large opening, and the tail of the booster no longer emitted flames, and then the motorized nozzle next to the booster slammed outward, allowing it to quickly move away from the carrier.

The vehicle flew upwards according to inertia, then the engine ignited at high altitude and continued to push it into space.

Generally, it only takes a few minutes for a rocket to take off to enter space, and the Yishan rocket is no exception.

When the launch vehicle of the Yishan rocket went into space and climbed a certain orbit, the cargo hatch was finally opened.

Only now do people know what is in it.

"Look at it...... It turned out to be a maintenance module ?! ”

"I thought that the module in the commercial area would be launched first, but I didn't expect that the module in the industrial area would be launched first, or the maintenance module."

"Ah, what's the problem, is there anything particular about this firing sequence?"

"There's no problem, it depends on the Navigator's plan, it's just that it skips the commercial area and launches directly to the industrial area, how can this maintenance cabin dock with the rotating simulated gravity cabin?"

"Actually, it's okay not to dock, it's not that humans haven't built a single space station, just treat it as a single space station, and wait for the modules in each area to complete the assembly, and then they will dock together."

"I guess the navigator is planning to change his path, not engage in business, and start engaging in scientific research, to put it mildly...... With this maintenance pod, humans can repair satellites in space, right? ”

"What a change of way, I suddenly thought of an advertising slogan, I don't know if any brother sent it up for everyone to see, this is also a very profitable industry."

"Here it is, the advertising words: scrubbing at heights, dust removal on the surface of satellites, polishing and waxing of solar panels, painting and refurbishment of space stations, and maintenance of space shuttles. Large, cheap, invoiced, please consult the Navigator Aerospace Company Tang General Manager for details, telephone 138...... The back is casual. ”

"Hahaha, are all these years of funny jokes finally coming true? But why aren't you full of ads? What about the front? ”

"What's up ahead? Navigator is not an arms company? Aircraft carriers, submarines, nuclear warheads, fighter jets have nothing to do with them. ”

"How do you know it's okay? I'm afraid you don't know the relationship between domestic aerospace science and technology and aerospace science and industry, the navigator space station can be built, the rocket can be built, the lunar base can be built, and the orbital shuttle can be built, if you want to? What do you think these things can be converted into? ”

"Shhh I was shocked! ”

Many years ago, there was a funny picture on the Internet, and I forgot where the source was, that is, someone turned the brand P on the mobile tricycle into a "specialized aircraft carrier".

There is also a line of small print below: Satellite dust removal and waxing? Nuclear warheads refurbished!

The actual sign turned out to be "repair the roof leakage" and something like that.

Because I thought it was interesting, it spread? And the "project" is more and more filled, and finally it becomes a plain text mode.

But who would have thought that satellites that look like a joke would be waxed, oiled, and refurbished? But it is a high-tech industry with amazing profits in the future, far more promising than the rocket relaunch and utilization project that has only begun to heat up in recent years.

First, this is because the current rocket is still a means of transport facing high temperature, high pressure, and high-intensity external impact environment, and the one-time use of this means of transport itself is to improve reliability.

Because all the parts only need to work in a maximum of about 30 minutes to complete the task.

Forcibly increasing a high-risk engine system from a maximum of 30 minutes of reliability to 300 minutes, or even more, is very difficult in itself.

Especially when technology is insufficient.

In addition, there is no real economic benefit to the rocket itself, and the ultimate purpose of the rocket's work is to launch a payload into orbit.

This includes all satellites, spacecraft, space stations, deep space probes, and more.

That's what rocket work is all about.

And all these ballistic flying objects can be regarded as various "artificial satellites".

And the value of the satellites themselves, especially those large and heavy, in the vast majority of cases, far exceeds the cost of the rocket that launched them.

For most heavy satellites, even if their rocket can be reused 5 or even 10 times in a row, it is not as economical as having the satellite refurbished once.

Taking Tianxia's most common rockets and satellites as an example, the international launch price of the Changsanyi rocket is about 60 million to 70 million US dollars.

If the satellite platform launched is Dongfanghong-3, then the price of the star is about 200 million US dollars.

The price of a star based on the Dongfanghong-4 satellite platform may exceed 500 million.

The more advanced Dongfanghong-5 satellite platform even exceeds $1 billion.

This is a relatively cheap price, and if you buy similar satellites from the West, it may cost $1.5 billion a satellite.

Therefore, at present, when a country purchases large-capacity synchronous communication satellites, the party that sells the satellites simply "buys the satellites and sends them for launch."

The lifespan of a large-capacity communications satellite is 10 to 15 years, which is equivalent to the consumption of $100 million a year.

If it can be refurbished and extend its life by half or even two-thirds, it will create between $5 and $1 billion in value.

And more than ten years have passed, technology has definitely taken a big step forward, and it is not a simple saving to update its equipment at this time to make it more suitable for current and future tasks.

Not to mention how many rockets are enough to launch a rocket once extended, the fact that the rocket launch is "not 100% successful" is enough for many people to hesitate.

Yes, in case the launch fails, not only the money will be raised, but the future needs of the country will also be raised.

The delay in the launch of a satellite can affect a country's development strategy for years to come, if not longer.

For example, some countries have bought a meteorological satellite and want to rely on this satellite to realize their own weather forecasting, so as to get rid of the weather forecast control of some countries, and some countries in the province also carry private goods when providing meteorological data, but when these satellites fail to launch, they must continue to be patient in the next few years.

But when "this satellite" is already in orbit in space, that's two things.

As long as you don't actively slow down the satellite and then let it quickly enter the atmosphere and burn up, it can stay in Earth orbit for a long time.

Wouldn't it be safe and advanced if it could be replaced with parts and fueled at this time, so that it could be used like this year's satellite from a decade ago?

And there's an even more brilliant way.

Country A does not have satellites in space and cannot be upgraded, so country B can even repair and upgrade its own obsolete orbital satellites, upgrade them, and sell them directly to country A in space!
