Chapter 788 (1/2)

after the foundation construction, the following is the ground construction.

The first thing to build is not the houses in the city, but the huge dome surrounding the city.

The air on Mars cannot be breathed, and the temperature of Mars is not suitable for human survival.

So this Mars immigrant city, Yeosu, designed a totally enclosed structure.

Only a fully enclosed urban structure can resist the extreme environment on Mars and protect the safety of the residents in the city.

Dome is to ensure the safety of the city, isolated from the external environment of Mars.

The whole dome is a semicircular bowl, which is directly buckled to the city to form a safe space and protect the whole city.

Originally, when designing the city, Yesu planned to use the same design as the Mars base.

The buildings in the whole city are designed to be closed, and then all the buildings are connected through some passageways.

This kind of design is undoubtedly the most convenient choice, and the construction difficulty is countless times lower.

But in the end, Yesu abandoned the design and decided to adopt the conventional urban layout instead of the design of the Mars base.

The reason why Ye Su didn't adopt the design idea of Mars base is mainly for the consideration of the life of the residents in the city.

Living in a fully enclosed building, people will have a depressive mood for a long time, which is very harmful to mental health.

Mars base can be designed in this way, because it is full of astronauts who have their own missions on Mars.

And astronauts are in rotation at any time, and will not stay on Mars for a long time.

The residents of Mars city are quite different. If they are allowed to live in closed buildings in the future, it is estimated that some people will go crazy soon.

Therefore, Mars city should at least use a certain amount of external space for the residents in the city.

In the end, ye sucai chose the present design scheme. All the buildings were in the open air environment.

Yesu, the Martian City, plans to arrange ordinary buildings in the city, which are exactly the same as those on earth, and will not allow all buildings to be closed.

But such a design pattern needs to design a protective layer on the periphery to isolate the whole city from the outside environment.

So Yesu came up with a way to protect the city by building a dome.

Yesu plans to build a huge dome on the outskirts of the city to surround the whole city.

In this way, the low temperature outside and the air that is not suitable for human breathing can not affect the human beings in the city.

The whole dome is like an umbrella to protect the people inside.

Although this kind of design scheme is much better for the residents inside, it also adds numerous difficulties to the construction.

It's hard to think about the huge dome that surrounds the city.

On earth, just building a dome that surrounds a stadium doesn't know how much effort it takes.
