"But for the space industry, it's small enough, we only need to make minor internal modifications to the existing spacecraft, so that they can communicate with the surface without delay in space, video chat, and watch live broadcasts. ”

"They can receive information from Aqua Blue in real time, so that the space trip does not have to be so boring, and they can also conduct real-time three-dimensional videos with their families to relieve the pain of missing their loved ones, and they can also log in to the second world in space, etc. ”

"This is very helpful for going further into deep space in the future, because one of the hardest problems in space exploration is actually the mental health of astronauts. Feng Ping explained one by one.

Quantum communication technology was born for space, and it is enough to be able to do that.

However, Li Quan thought more, and after a short period of thought, Li Quan decided to weaken quantum communication, at least temporarily, and it could be slowly improved later.

So he said: "The current 5G+ is enough for the time being, this technical upgrade will disrupt the existing social order all of a sudden, it only needs to be applied to space for the time being, and the speed must be limited, 10PB/S is too strong, limited to 100GB/S, a little weaker than the surface." ”

After thinking about it, Li Quan asked, "How big does this quantum communication terminal need to occupy, and can it be expanded later?"

"Back to Your Majesty, it depends on the number of users, according to the current population of Aqua Blue Star, even if it is for all human beings in the world, it only needs to cover an area of about four or five square kilometers, but in fact, it is impossible to use it all over the world, and it is very high to be able to use it by half of the people. As for the later expansion, there is no problem," Feng Ping said after thinking about it.

Li Quan nodded after understanding the situation: "Now that the population of Water Blue Star is skyrocketing, you can directly build a terminal that can provide 10 billion users this time, and it will be built on Zhenguan Island, where there is no development now, and I don't plan to carry out other development in the future, but it can facilitate future expansion." ”

"Yes, Your Majesty, the minister knows. Feng Ping understood what Li Quan meant.

"Although quantum communication technology cannot be popularized in Aqua Blue Star for the time being, important departments such as the research institute and the military department of the empire can give priority to the use of it without speed limit, and some important enterprises of the empire can also use the speed limit according to their needs, as for the civilian use for the time being. Li Quan said.

"Yes, Your Majesty, the minister will arrange it now, and the minister will retire. ”

Li Quan looked at Feng Ping, who left, the success of quantum communication technology has solved one of the two major problems in space, and the next one is stellar wireless power transmission, which is solved, and the solar system can be left to human beings.

By the way, the speed of the spacecraft is also a very big problem, but there is no solution for this for the time being, because there is no more advanced engine technology for the spacecraft in the system mall, and what is more advanced than the current civilian spacecraft is the engine technology of the military spacecraft.

But that speed is only about four times the speed of a civilian spacecraft, which is a drop in the bucket for the huge universe.

Before the system upgrade, the maximum speed of the ship could be the speed of a military spaceship.

At present, the spaceships of the New Tang Empire are divided into export-oriented spaceships and civilian spaceships.

At present, the military spacecraft are Kunpeng aerospace fighters and armed spacecraft modified from civilian spacecraft, and the real military spacecraft has not yet been exchanged.

However, despite this, the exploration spacecraft is the fastest and the passenger spacecraft is the slowest among the export spacecraft.

Passenger spacecraft can reach up to 250,000 km/h at the fastest without using planetary acceleration, which means that it can travel a distance of 6 million kilometers a day, which is very terrifying.

But according to the distance of the Sun from Aqua Blue Star, it is about 150 million kilometers.

That is, it would take 24 days for a passenger spacecraft to fly from Aqua Blue to the Sun without counting the gravitational pull of the planet on it.

Of course, no one is stupid enough to fly to the sun, but people will expect to fly out of the solar system, but the solar system is very big, bigger than people think.

Outside the mainstream planets of the solar system is the Kuiper Belt, where tens of millions of asteroids are distributed, but all of them are less than 3,000 kilometers in diameter, at least no asteroids larger than 3,000 kilometers in diameter have been found.

It should be the remnants of the star's debris from the early days of the formation of the sun.

So is the Kuiper Belt the boundary of the solar system, no, the solar system is much larger than people think, and there is an Ultra Nebula belt about two light-years or so outside the Kuiper belt.

There are hundreds of billions of comets scattered here, all of which were frozen in primordial ice and formed in the early days of the sun.

So there is water in space, there is, and there are a lot of them, and the comets here have abundant water resources.

Although the solar system is very small to the Milky Way, like dust, and the Milky Way is like dust to the universe, it seems that the water blue star is not dust to the entire solar system, so human beings should learn to revere the universe.

Even the solar system in which humans live is already measured in light years.

And how long is the distance of a light year, 9.46 trillion kilometers, compared to this, the distance from Aqua Blue Star to the Sun is basically negligible.

And if humans want to fly out of the solar system in a passenger spacecraft, they can only fly 2.19 billion kilometers a year, which will take about 8,500 years.

The fastest exploration ship is 2.5 times faster than a passenger spacecraft, which is about 3,400 years.

The speed of the civilian spacecraft used by the New Tang Empire itself can reach about fifteen times that of the export exploration spacecraft at the fastest, and it will take about 230 years to fly out of the solar system.

Even if the most advanced military spacecraft were to be used in the future, the speed would be increased by four times, and it would take about fifty or sixty years to fly out of the solar system.

This is also the reason why although the New Tang Empire observed the probe flying from Proxima Centauri into the solar system, they couldn't do anything about it for the time being, it was too far away.

And all of the above is ideal, in fact, because of the fuel, the spacecraft cannot start all the time, and sometimes it needs to be accelerated with the help of the gravitational pull of the planet.

In addition, the greater the velocity, the greater the mass, and the gravitational pull of the small star can be accelerated, and at the same time, it will slow down the spacecraft after flying a certain distance.

In short, in a word, at this stage, human beings can only operate within the Kuiper Belt, and even this area is enough for human exploration for a hundred years, a thousand years, or even longer.

Hey, there's a long way to go.

NTVOton needs itself, human beings need themselves even more, without me Li Quan, it is really hard to imagine how long it will take for human beings to leave the solar system, maybe never.

Aqua Blue Star Space City.

"What are you doing over there, why is it closed? I want to go to the border to see it." "There are tourists who come to Space City for unknown reasons, so I asked the tour guide.

"Oh, the second phase of the Space City project is underway over there, and the Space City still needs to be expanded in the future. The tour guide explained with a smile.

After hearing this, the tourist looked incredulous: "This space city is so big, and it needs to be expanded, can it use such a big place?" But this New Tang Dynasty Empire is really rich." ”
