Chapter 1093 (1/2)

As the center of the colony, it was the main place where the colonists lived, worked, socialized and entertained, with all kinds of facilities.

Around the colony cabin, there are also four spherical buildings of graphene material, which are connected with the colonial cabin by a man holding thick and thin pipelines. Don't underestimate these four spherical buildings. They are the lifeline of the whole colony.

As we all know, Mars is a planet covered with desert and volcanic ash, giving people the intuitive impression that it is an extremely dry planet.

However, on the contrary, as early as a few years ago, according to the data sent back by the curiosity Mars probe, NASA concluded that Mars is not only not short of water, but also rich in water resources! However, most of these water are brines, and most of them are buried in the ground or seeped in the sandy soil layer, so they can not be directly drunk.

However, for the star ring trade, this is not a problem. As long as there is water, there must be a way to turn it into drinkable water. The four bulbous buildings are nothing else. Their meaning is equivalent to the pumping pump of the colony or the one with its own filtration capacity.

The site of the colony was originally located on the lake bed where the ancient sedimentary facies could be observed. There must be no water shortage under the foot. The four spherical pumps first pump the underground brine into the spherical storage tank, and then filter it. Finally, the water is continuously transported to the colony tank through the pipeline.

Water is the source of life. Whether we can realize the self-sufficiency of drinking water is the key to realize the self-sufficiency of Mars colony.

After water, it's oxygen.

Mars's oxygen content is so low that billions of years of oxygen have either run away, or they've gone with iron everywhere. Fortunately, there is an atmosphere here. There is no oxygen but carbon dioxide. It is much easier to solve the oxygen problem than the moon. There is no need to use electrolytic water to waste electricity. After all, there is no helium 3 on Mars to exploit, and the energy is still very expensive.

The problem of oxygen can be solved with food.

The main component of the Martian atmosphere is carbon dioxide, followed by nitrogen, oxygen and water vapor, which are almost negligible. For animals, it's hell, but for plants, it's heaven!

Of course, this is not to say that plants can be directly planted on Mars, not to mention how cold the surface of Mars is. Long time exposure to pure carbon dioxide will also lead to ”photosynthetic adaptation” of plants, thus hindering crop growth.

However, as long as nitrogen is used to control the carbon dioxide concentration in the plantation, it is easy to keep the crops in the plantation under the optimal carbon dioxide concentration. With the appropriate amount of water supply and ultraviolet light, the growth rate of crops is not too fast!

The only drawback is that the initial investment is a little high. For the sake of the ration of these 20 people, the cost of the whole equipment will cost hundreds of millions. If put on the earth, 100 million SGD would be enough to cultivate hundreds of thousands of mu of good farmland.

In the future, Jiang Chen plans to establish itself as an industrial base in the future. With the shipbuilding technology of the future heavy industry, the star ring trade will get more ”seagulls” to expand its transportation capacity, and the grain and other things will be transported directly from the earth. It's hard to find a way to farm in the desert without developing such a large granary.

Apart from other things, Guanghan City has the advantage of low power cost at least, so it is justifiable to plant some grain to relieve the supply pressure. There is no helium 3 or pure water on Mars, so you can lose as much food as you produce.

Of course, Jiang Chen did not think of transforming Mars into an earth like planet before. In other words, he was not the only one who had proposed a plan to transform Mars a long time ago.

One of the most famous is Elon Musk, CEO of SpaceX, who has always been obsessed with Mars. It has to be said that this product is a genius. He proposed the shocking method of constantly dropping nuclear bombs at the poles of Mars. Nuclear explosion melts dry ice, thickens atmosphere, causes greenhouse effect, melts more dry ice, continues to thicken atmosphere The central idea of the whole method is to use nuclear bombs to leverage the lever of greenhouse effect. Although it sounds like a heresy, it makes sense in theory, and it is simple and crude.

But Jiang Chen also thought about it, and then gave up the idea.

There is no other reason. It's too slow to play like this. It's easy to pry this ”lever”, but don't even think about it without thousands of years. The most important thing is that there are too many uncertainties in this plan, and Mars is the most important link in the plan of forming ”invincible fleet” in the future of star ring trade. If one of them is not fun to leave, there will be no place to cry.

Of course, although he gave up his plan to change the topography of Mars in the short term, this does not mean that Jiang Chen completely gave up his plan to transform Mars into an earth like planet.

To the north of the colony cabin is the plantation, which is the largest building in the colony except the colonial cabin. It is connected with the water storage tank and the colony cabin by pipelines.
