Chapter 277 Lighting Conditions of Mars

Estimates of the value of the Spirit Star based on the human value of Blue Star are as high as about 10 million trillion dollars.

It is higher than the total production value created by Blue Star mankind from ancient times to the present, which is 400 trillion meters.

And this asteroid is not too far away from our blue star, about 370 million kilometers.

It is located in the asteroid belt between Mars and Jupiter.

Of course, this extremely valuable asteroid was not discovered only in the 21st century. In fact, it was already detected by Italian astronomer Gasparis as early as 1852. .

This is an M-type asteroid, composed of a metallic core.

From the surface, this celestial body is sparkling and covered with gold.

Moreover, this spiritual star also contains a large amount of platinum, nickel, titanium and other metals.

According to astronomers' observations, the gold contained in Psyche is more than 100 million times the amount currently detected in our blue star.

Of course, this is not absolute, because you can control the amount of mining. For example, diamonds are everywhere in Nanfei, and they can even be synthesized. But why are they still so expensive? It’s not because of good sales and publicity control. .

Some time later, the planet Theia unfortunately had a violent collision with the Blue Star.

It is conceivable that if such a high content of gold is placed in our Blue Star, then everyone in Blue Star can become a billionaire.

And even if such an asteroid made of gold is placed on Blue Star, it is impossible for everyone on Blue Star to become rich. Just like those oil companies, the rich are only the royal family, not ordinary people. What about oil exploration rights?
The so-called M-type asteroids are objects with a metallic core.

But after all, things are rare and valuable. If the gold of Spirit Star is developed in the future, then it is very likely that the environment will not be so precious.

As for why Spirit Star became an asteroid with only a star core, the situation it encountered was probably somewhat similar to Blue Star.

It was such an impact that directly knocked out the components of the Blue Star's core, and a large number of fragments were knocked out of the Blue Star's surface.

About 4.6 billion years ago, that is when Blue Star was just born.

After orbiting around the blue star for a period of time, the moon we see now was formed.

Near the Blue Star is a celestial body similar in size to Mars, called the planet Theia.

And these celestial bodies are actually very similar to Blue Star, because Blue Star is an M-type planet.

At that time, humans will most likely use gold to build houses.

Love is everlasting and diamonds last forever are not all deceptive propaganda. So as long as the production of gold is controlled well, it can naturally be promoted as a testimony from the starry sky 300 million kilometers away, and maybe it will Will be more popular or something.

This is the most accepted speculation by the scientific community so far about how the moon was formed.

And why does the Spirit Star expose its metal core? The cause of its formation is likely to be similar to the impact of Blue Star 4.6 billion years ago.

It is also possible that Psyche was a very large object a long time ago. But it was only after the impact that it became what it is now. The rock material that was originally wrapped on the outside was peeled off during the impact because it was not strong enough, leaving behind a relatively large and very solid metal core.

This is just like the Blue Star. In fact, the Blue Star contains a lot of gold. However, as a large-mass metal, gold naturally sank into the core of the planet, leaving less than 100 million points on the surface. Just a remnant of one.

But all this has nothing to do with Liu Xiu, because with today's aerospace capabilities, it is extremely difficult to reach Mars, let alone Lingshen Planet. After all, reaching Lingshen Planet at this speed would be at least It would take five times more time.

Therefore, it will take at least three years to carry out mining operations on the Spirit Star.

After a day of hard work by Liu Xiu and other nineteen people, a 200-square-meter Martian version of the vegetable greenhouse has been successfully erected.

Of course, for the sake of sealing effect, the vegetable greenhouse on Mars cannot be built directly on the land of Mars like the one on Blue Star, because there is no way to seal it. After all, the land on Mars does not have an airtight effect.

Therefore, the vegetable greenhouse of Mars is actually built on a piece of spliced ​​aluminum plate. The thickness of this aluminum plate is also the same as the thickness of the prefabricated house built by Liu Xiu and the others yesterday, one centimeter thick, and it can still be used universally. kind.

The double-layered one-millimeter membrane of the greenhouse is built on this aluminum plate. In order to seal, it is clamped with glued aluminum plywood and finally fixed with screws, so there is no need to worry about air leakage.

After all, it is still double-layered, and the outer layer is not filled with a lot of gas. It is mainly for the double-layer sealing effect, because if the air pressure of the outer layer increases, it will naturally indicate air leakage, which has the effect of double-layer protection.

There is also a 20-centimeter-high baffle erected on the aluminum plate on the ground, which is actually used to place soil.

You must know that it is definitely unrealistic to simply rely on the soil on Mars for planting.

Instead, we first use the organic soil brought here, that is, the black soil, for planting, because we need to quickly establish the ecology here.

You must know that although there is still a lot of oxygen and hydrogen left on the space station, you cannot simply rely on these!
What's more, only successfully establishing its ecological cycle system on Mars means successfully taking root on Mars.

As for using Martian soil to grow vegetables and other plants, we still have to wait until the Mars base is operating smoothly and can be self-sufficient before conducting this experiment.

Time passed very quickly during construction, and a month passed in the blink of an eye.

In this month, Liu Xiu and others also went back once. This time they went back naturally to continue transporting the construction materials and supplies from the space station, and by the way, they also brought Wu Qianli and one other person who were staying on the space station. Give them some rotation and let them get in touch with the gravity on Mars for a while.

After all, always carrying it on the space station will affect the body, such as osteoporosis and other symptoms.

Therefore, it is still necessary to rotate. After Liu Xiu and others return in the future, the space station will naturally rotate every six months or so to prevent anything from happening to the people staying in the space station.

The materials transported to the space station this time mainly include a large number of solar power panels, as well as some small mining and refining equipment.

There is no way, although the 100 square meters of prefabricated houses on the base have been covered with solar panels.

But for a hundred square meters of power generation panels, even if Liu Xiu used the most advanced and best solar power generation panels, the light energy conversion efficiency reached 30%, but because Mars is further away from the sun than Blue Star.

Therefore, the light intensity in the Mars orbit is actually only about 40% of that of the Blue Star. For example, the light intensity in the Blue Star orbit is more than 1,300 watts per square meter, while the light intensity in the Mars orbit is only more than 500 watts per square meter. Watt's light intensity.
