Moreover, astronauts are constantly rotating and won't stay on Mars for long.

The residents inside Mars City are completely different; if they are always confined to enclosed buildings, it's likely someone will go insane before long.

Therefore, Mars City must have a certain amount of external space for residents to move around.

Finally, Jiang Cheng settled on the current design plan, where all the buildings are situated in an open environment.

Jiang Cheng plans to arrange ordinary buildings inside Mars City, identical to those on Water Ball, and not have them all sealed.

But such a design requires a protective layer in the outer area to isolate the entire city from the outside environment.

So Jiang Cheng came up with a solution: to protect the city by building a dome.

Jiang Cheng plans to construct a massive dome in the outer area of the city to surround it.

This way, the outside low temperatures and unbreathable air will no longer affect the humans inside the city.

The entire dome functions like a protective shell, shielding the humans inside.

While this design is beneficial for the city's residents, it poses innumerable challenges for construction.

Just imagining the construction of a colossal dome encompassing the city reveals how difficult a task it is.

On Water Ball, building just the roof of a stadium was already a laborious effort.

Now, Jiang Cheng's task of building a dome around an entire city is a super-engineering feat.

It's fair to say that the dome's construction is the most challenging and intricate aspect of the entire project.

Jiang Cheng is currently focused on this aspect, facing the largest hurdle in the project.

How to construct this gigantic dome is Jiang Cheng's current concern.

The building materials for the dome have arrived, I certainly don't want to see a lack of materials during construction.

Jiang Cheng is in the engineering command center, inquiring about the materials.

Building such a massive dome requires an astronomical amount of materials.

The total materials needed for the dome might even exceed those required for the entire city.

From the project perspective, more than half of the entire effort goes into building the dome, which explains Jiang Cheng's concern here.

Construction of the dome is about to commence, and a shortage of materials would drastically slow down the project.

The last batch of materials has been completed and is ready to be shipped from Water Ball. "President Jiang, you don't need to worry about the materials; they can certainly keep up with our construction progress."

We confirmed this with Water Ball yesterday, so we are very clear about the situation.

The materials for constructing the dome are quite special and can't be produced on Mars, requiring pre-manufacturing on Water Ball before being transported to Mars for assembly.

Many materials for building Mars City are sourced locally from Mars.

After years of development, Mars' mining industry is quite advanced, providing resources for construction operations.

However, due to production difficulties, many materials still need to be transported from Water Ball, including those for the dome.

The dome, designed by Jiang Cheng, uses transparent material far more durable than steel, resisting Mars' harsh climate.

Such advanced materials cannot be produced on Mars and must be shipped over.

The dome, built with transparent materials, is indeed transparent, allowing the city to boast a transparent dome.

Imagine the future residents of the city being able to look up and see the Martian night sky—it's simply fantastic.

If the dome weren't transparent, the city's residents would feel like they were living inside a large stadium.

Nobody would enjoy this feeling; it's not much different from living in sealed buildings.

Because of considerations like these, Jiang Cheng decided to use transparent material for the dome.

Of course, using transparent material significantly increases construction difficulty.

Transportation of such materials is a major issue; the Pioneer has been frequently transporting dome materials back and forth.

Almost all materials shipped from Water Ball are primarily for the dome.

Once all the dome modules are prefabricated, they will be transported from Water Ball to Mars.

Then, these prefabricated sections will be assembled on Mars to complete the dome.

The process seems very complicated, adding several more steps compared to direct construction.

Transporting prefabricated blocks is a major issue since moving completed modules is far more difficult than raw materials, and producing them on Water Ball was very troublesome too.

The Pioneer has made several trips recently to transport these prefabricated blocks.

Almost all materials transported from Water Ball are primarily for the dome.

This is why Jiang Cheng pays so much attention here, worrying that the prefabricated blocks won't be transported to Mars on time.

Although this construction technology involves complicated transport and advance manufacturing, it does have its advantages.

The benefits become apparent during construction, making the building process several times more convenient than usual methods.

Since all transported items are prefabricated dome modules, Jiang Cheng's team only needs to assemble them.

The only thing to note during assembly is the sequential numbering of modules, as each has a unique shape, and incorrect installation would be troublesome.

This dome construction approach greatly reduces construction difficulties.

Otherwise, attempting to build such a large dome on Mars would be an impossible task.

Constructing such a massive dome on Water Ball alone is challenging enough, let alone on Mars under harsh conditions.

Fortunately, Jiang Cheng now only needs to worry about arranging the assembly work.

All modules have been numbered in advance, and astronauts only need to assemble the dome according to these numbers.

Although the dome project is extensive, robotic assistance is available, making the task feasible.

If Jiang Cheng directs well, a transparent giant dome will rise on Mars.

Once the dome is completed, subsequent construction will become much more straightforward.

With the dome protecting all, astronauts can work without worrying about the external environment and focus solely on their tasks.

When the Pioneer finally arrives on Mars, loaded with the last batch of modules, the transparent dome is still under construction.
