The Nautilus isn't huge, but it's okay to pull all nine other astronauts aboard.

It's just that the materials that advance to the base can only be temporarily placed here, and there is no place to put those materials "Nautilus". After all, the "Nautilus" is just the personal spaceship of the old man Andro, and the purpose is to pull the old man Andro around. As for supplies, do you think a person with a stellar star core needs to pull additional supplies? In the star core space, there is nothing to be found!

And in the cabin of the "Nautilus", there are no other chairs except for the helm seat where Tang Feng sits. However, the Nautilus, whether it was launched or flown off, did not cause any discomfort to the people in the cabin. Anthony: Even if they were standing in the cabin, it didn't matter.

With the experience of the first test flight, Tang Feng did not adjust the power output of the "Nautilus" to such a large size this time, but even so, the "Nautilus" only took more than ten seconds to arrive at a distance of more than 700 kilometers.

The "Nautilus" was a supership between the rivers in the past, and the flight distance was often calculated in millions of light years, but now in the hands of this new owner, it actually flies in the atmosphere, which is no different from using a Bugatti Veyron to pull a plow in the fields on Earth.

George. Anthony: Although they have seen this alien base up close through the camera, where can they come to this base in person?

Therefore, as soon as they entered the gate of the base and took off their spacesuits, these people were in Han. Led by Alexander, he began to take a closer look at this magnificent alien base, oh no, it should be called the Hope Base now.

As for Tang Feng, he didn't follow them to continue to visit the base, he came to the main control room of the base, and some things needed to be prepared by him in advance.

The people of the Doug family have almost the same genes as the earthlings, so the air they breathe and the food they eat are basically the same as the earthlings. It's just that when this base was built, it was built according to the conditions that could ensure the survival of tens of thousands of Doug family members, and later when only the thirteen people left in this base, many areas of the base were idle.

In addition to the large hangar, the base has a total of twenty-eight floors in the main base, which is six kilometers deep. Among the twenty-eight floors, except for the core layer at the bottom, the other twenty-seven floors are all living floors.

Among the 27 living layers, there is a living layer for the Doug family to rest, a research layer for scientific researchers, a mineral processing layer for processing Martian minerals into various raw materials, a precision casting layer for manufacturing various equipment and parts, a planting layer for growing grain, vegetables and fruits, and a breeding layer for captive livestock

For example, the planting layer used to grow grain, fruits and vegetables and the breeding layer used to raise livestock in captivity are the most layered, with a total of 18 layers, of which there are eight layers dedicated to growing grain, four layers are used to grow fruits and vegetables, and six layers are used to breed livestock.

The area of the main base is also very large, with an area of 20 square kilometers on the first floor. Like the planting layer used to grow grain, the eight layers are a total area of 160 square kilometers, that is, a total area of 240,000 mu.

According to the average output of wheat, corn, and rice on the earth, about 400 kilograms can be produced per acre of land, and these 240,000 mu of land can produce nearly 100,000 tons of grain in one season, which is enough for 500,000 people to eat for a year.

Don't forget, according to Tang Feng's understanding of the base, the planting layer can produce two or even three seasons of grain crops a year because of the artificial sun and temperature control system

It is no exaggeration to say that even the most fertile land on earth is not as productive as the plantation layer at this base because of the use of extremely sophisticated agricultural technology. The technology of aliens is not only reflected in those high-tech aspects, such as planting and breeding, which are the most basic but important technologies, and they are also many generations ahead of Earth.

It's just that most of Eric's people left Mars early, and there are only thirteen of Eric and them left in this huge base, so these planting layers and breeding layers are only a small part of them.

Now Tang Feng needs to understand all the situation of these planting layers and breeding layers, because the crops of the Doug family were planted here, and after the earthlings came here, they needed to plant crops on the earth, so Tang Feng had to find out about the light time of the artificial sun, the amount of irrigation, the pH of the soil, and the temperature control of the planting layer.

Of course, when Tang Feng figured out how to control zhì, he still needed to be like Jimmy. Johnson also has plant experts like Sun Wei to give precise numbers jù, and then Tang Feng can adjust the various numbers of the planting layer according to these numbers.

The planting layer and breeding layer are an important foundation for earthlings to immigrate to Mars on a large scale, and without them, even if they have this Martian base, earthlings will not be able to survive on Mars for a long time.

The equipment of this hope base is extremely perfect, and some of the equipment left by Eric before they left, through the control of the main control console, let the nanomachine qì people transform it, and it can become a variety of processing machinery that can be used by earthlings, and the mining equipment produced by these equipment can also be used for mineral collection on Mars, and become raw materials for various parts and equipment in the mineral processing layer.

In this way, chickens lay eggs, eggs lay chickens, and it won't be long before this base can meet the needs of earthlings for various industrial equipment.

If earthlings want to survive on Mars for a long time, food, fruits and vegetables, meat, and various machinery and equipment are indispensable. Although this foundation can accommodate 500,000 to 800,000 people to survive here for a long time, this number is still too small compared to the huge population base on the planet.

In order to truly allow earthlings to immigrate to Mars, it is also necessary to completely transform Mars. Of course, that would only be possible after the Split of the Star Core had completely taken control of Mars. Now, with this Martian base, a solid Martian bridgehead has been formed.

As the controller of the Hope Base, Tang Feng must make all kinds of preparations in advance. Therefore, after Tang Feng was busy in the main control room for three days, he basically understood the situation of the entire base.

However, during this period, Tang Feng also discovered a very interesting thing. This thing is extremely rare for earthlings, even rarer than the helium-3 that Tang Feng once made, but in the Hope Base, this kind of thing is very abundant.

This discovery also made Tang Feng a little ecstatic. If nothing else, as long as you bring this thing back to Earth, the cost of this manned Mars exploration program will be fully recovered (to be continued). )
