The "Nantianmen" space station was not originally called by this name. Pen & Fun & Pavilion www.biquge.info can even be said that it originally had no name, only a number.

Although the space elevator was still a miracle a hundred years ago, it was only one of the 12 space elevators responsible for transporting water into space in this era, and it was no different from the other 11 space elevators built on the sea, and it was completely the result of mass production.

The huge gravity of the earth determines that if human beings want to truly enter the cosmic age, they must use the moon as a springboard.

Although the moon is rich in metal content for human development of the space industry, the water content is very small, and it is difficult to extract, and it is impossible to rely on the little water on the moon to maintain the daily needs of tens of millions of people.

The space elevators at these base stations on the surface of the sea were originally built with one purpose in mind: to carry water into space.

Therefore, this space station with a base station on top of a space elevator on the surface of the sea is not like most land-based space elevator top space stations, which have gradually developed into small space cities over time.

Originally, these space stations were built without even considering the survival of human beings, let alone using centrifugal force to simulate gravity, and there was no design for air circulation systems.

This large "wheel" with a diameter of 800 meters was actually built from materials from the moon at the spacecraft factory in the "Tiangong", and then transported from the "Tiangong" to geosynchronous orbit.

In this way, these space stations, which were originally used to carry water, were adapted so that they could also transport tourists into space.

The name "Nantianmen" was also chosen at that time, implying that this space station will become a transit station from the earth to the "Heavenly Palace".

When the space elevator stopped, it was the same process of separation between the space elevator and the cable as on the ground, and then another space elevator that was already ready to carry the passengers who were going back to Earth to the ground.

Since it is now a gravity-free environment, the process of switching elevators is much easier than on Earth.

Then Lu Ze and the space elevator they were riding passed through a tunnel and stopped on the spinning "wheel".

The centrifugal force generated by the rotation of the "wheel" simulates a slightly lower gravity than the gravity of the earth's surface, about 0.8g, so they can walk more easily.

This kind of simulated gravity is very necessary, if there is no gravity, just let the passengers in these space elevators leave the space elevator by themselves in a gravity-free environment is a big problem, all the passengers have not been trained to move in a gravity-free environment, so many people together will inevitably have bumps and bumps.

The three of them lined up again, and since they were on the top floor, they waited a full twenty minutes before leaving the space elevator.

The "Nantianmen" space station has a radius of 400 meters and a width of only 400 meters, which is far inferior to the base station on the ground in terms of size.

It's just a transit point for travelers to take a break, no one lives here, but the environment is not bad, and there are even plants for decoration.

Lu Ze will stay here for an hour, and then leave the space station together on the spaceship that had sailed from the "Heavenly Palace" to transport passengers returning to Earth, and go to the "Heavenly Palace".

Although Lu Ze and Lu Li only vaguely put forward the idea of going to space to see when they chatted at the beginning, how could they really enter space if they only went back and forth between the ground and the synchronous orbit once?

Compared with the space stations that can only live hundreds to thousands of people in geosynchronous orbit, the number of people living in "Tiangong" for a long time has reached 5 million, which is suitable as the destination of Lu Ze's trip.

All three of them were in space for the first time, and they had been fixed to their chairs since the second acceleration of the space elevator, and they had not been able to really see the Earth from space.

The station was clearly built with this in mind, with huge floor-to-ceiling windows on the side close to Earth dedicated to visitors admiring the Earth.

The floor-to-ceiling window was 50 meters high, and they could see the Earth in front of them from a long distance as soon as they got off the space elevator.

Because gravity in the space station comes entirely from the centrifugal force generated by the rotation of the "wheels", its direction is exactly perpendicular to the direction of the Earth's gravity, so the Earth is no longer located under the feet, but directly in front of the floor-to-ceiling windows.

Although it is 36,000 kilometers above the Earth's surface, the Earth still looks huge, 40 times larger in diameter than the Moon when seen from the ground.

At the same time, the Earth seen in the space station is slowly rotating, not because of the Earth's rotation, but because the "wheel" rotates about every 45 seconds, so the Earth as seen rotates every 45 seconds.

The three of them walked in the direction of the floor-to-ceiling windows, near which was a row of tables and chairs.

Like the base station on the ground, there will be food and beverage for passengers, and it will be in the form of a buffet.

However, the food here is not made from the meat of various plants or animals, as they have eaten in the past, but some colorful balls that look like crystals.

The largest ball is the size of a ping-pong ball, and the smaller one is only a little bigger than a grain of rice.

But no matter what kind of food it is, it has one characteristic, and that is that it must be spherical in shape.

"Are these really food?" Lu Ze decided to ask Tianhuo, a professional.

"That's right, these are food, but it's not food on Earth, it's a lunar specialty from the 'Heavenly Palace'."

Sure enough, Tianhuo was immediately introduced to Lu Ze.

"These ornamental-looking balls are actually food synthesized from factories, unlike the earth, where the food produced by machines is still made from the meat of crops or animals, while most of the food in space is synthesized directly from factories."

In fact, a little calculation can be known, although today's technology can use nuclear fusion to generate energy, using lights instead of sunlight to grow crops, but such planting methods have high requirements for soil and water, with the current technology of human beings, the water needed to maintain daily life is already the limit of space, and this water must also be recycled.

It would be impossible to use water to grow food in space, or to transport large amounts of soil into space.

As for transporting food directly from the earth, there is no need to consider it, these tens of millions of people eat nearly 10,000 tons of food every day, which is larger than the combined carrying capacity of all the current human space elevators, so it has become an inevitable choice to synthesize food from factories.

"Although there are many plants and animals on the earth, they are all sent to space as experimental objects, and it is impossible to satisfy people's appetites. Real earth food is available, but it is scarce. Tianhuo said again.

Hearing this, Lu Ze was taken aback, and only then did he realize that although on the earth, human civilization had already developed to an era of great material abundance. But in this vast space, human civilization is still in the toddler stage, and it is impossible to have everything you want as you do on Earth.

For example, the food here is prepared in advance, and the travelers can only choose in it, and it is impossible to make it for him immediately if he wants anything like the earth.

As for the food on the earth, is there really no food?

Lu Ze didn't believe it.

Just as He Ruiyin can carry her box into space, it's not impossible for other people to really want to carry food into space, but will people who carry food into space share it with other strangers?

Apparently not.

Because these foods are their personal belongings.

If a person goes to space without food, they will have to eat food synthesized in the factory.

"Then why are all these foods spherical?" He Ruiyin said curiously.

Tianhuo said: "Not all synthetic foods are spherical in this way, it's just that this kind of spherical food is more common. If you want to eat other foods, you will naturally have the opportunity to taste them when you arrive at the 'Heavenly Palace'. ”

"And how are you going to eat these things?" Lu Ze asked.

Tianhuo began to introduce the two of them to how to eat these lunar specialties.

"Look at these white grains the size of mung beans, these are actually the staple foods that the factory synthesizes to replace rice."

Tianhuo said as he picked up a bowl and scooped it with a spoon.

Lu Ze and He Ruiyin also did the same.

Tianhuo pointed to a red ball the size of a ping-pong ball and said: "You can say that this is a chili pepper, of course, its taste is completely different from that of chili, and it is not only spicy, it also refers to the practice of 'opening the world mapo tofu', which is very suitable for rice, if you can eat spicy, the whole bite will be very refreshing." ”

When Lu Ze heard this, he immediately moved, and immediately scooped one up and ate it in one bite.

Although it is not tofu in taste, and the taste is 108,000 miles worse than the "groundbreaking mapo tofu" he ate at the beginning, I have to say that it is very suitable for this kind of synthetic rice.

Moreover, the rice synthesized by this factory is not dry and tasteless as described in the science fiction novels that Lu Ze has read in the past, but has a completely new taste that is different from any kind of rice on the earth.

Lu Ze couldn't help but ask, "Tianhuo, how do you know so much about these synthetic foods that only exist in space?" ”

Tianhuo smiled: "Because I came to space to study these synthetic foods well, although the earth can already provide me with endless ingredients, but it is always good to be exposed to some new things." ”

He Ruiyin also nodded in agreement: "That's right, only by getting in touch with some new things can we provide a steady stream of inspiration for innovation, for example, when I just took the elevator, I had some new ideas for the "Civilization" suite. Maybe the idea is a little too biased, but it's also good as a new song. ”
