284 Comet

However, it is also imperative to go to the Kuyinbo Belt to search for asteroids.

Because unlike the asteroid belt between wood and fire, the asteroids in the Kuyinbo belt receive almost zero sunlight and remain frozen all year round.

It is at a low temperature close to absolute zero all year round, and is filled with nitrogen ice and water ice. Pluto, the largest dwarf planet, is the best example. According to detection, it may even have a liquid ocean inside.

The water on Pluto alone can meet the needs of Mars in the future.

Of course, with current technology, the Moon Palace Base has no way to drag this entire dwarf planet into the inner solar system.

Even if it can be dragged in, there is no way to place it. After all, it is too big and there is no way to integrate it with planets such as Mars.

However, the asteroids in the Kuyinbo Belt are still very rich in water resources, and most of the comets in the solar system originate here.

Except for the comets that we can see that can pass through the barrier of Jupiter and penetrate deep into the inner solar system, the vast majority of comets actually orbit in the outer solar system. Because they never get close to the sun, their comet tails are almost invisible and cannot be displayed. reveal their identities.

In the universe, water is not actually a scarce resource, but there is really very little water that is clean and suitable for drinking.

Yang Qing plans to capture more than a hundred small comets with a diameter of more than one kilometer at least in the Kuyinbo belt and send them to Mars to serve as a water source.

After all, water is the source of life. Without enough water, even if Mars is transformed into a planet with suitable air temperature, it will not be able to establish a self-circulation process.

Under the combined influence of Yang Qing's goal and Xiao Ai who broke free from the restraints, the appearance of the moon suddenly changed with each passing day.

Just on this side of the moon facing Blue Star, more than 10,000 square kilometers of solar panels were installed in just three days, and this rate is still increasing at a rate of 5,000 square kilometers per day.

The consequence of this is that it is difficult to cover up the brilliance of the moon during the day.

Mirror-like solar panels not only absorb photons, but also re-reflect more than 30% of the sunlight back into the universe.

Although this reflection has been completely scattered after passing a distance of 380,000 kilometers, and there is no more dazzling light, it still makes the moon much brighter.

A little dazzling patch looks even more dazzling against a large, slightly dark background.

Some mines that have been developed for a long time are also fully accelerating production this time. The raw materials produced, such as pure titanium, aluminum and iron, are continuously transported to the base.

Aluminum reserves are very abundant. In the context of the moon's lack of oxygen, the deeply buried bauxite is also doped with a large amount of elemental aluminum or aluminum alloys.

In fact, under vacuum conditions, the physical properties of aluminum are absolutely no worse than those of titanium.

It is lighter and is composed of an alloy that is also as hard as steel.

More importantly, its cutting performance is far better than that of titanium alloy, and the production of aluminum is relatively simple.

Therefore, in the context of full-scale production expansion, new robots are mainly made of aluminum alloy.

Now that there is sufficient supply of raw materials, under the guidance of only life, the robot factory has demonstrated unparalleled efficiency.

The number of robots produced on the first day was only 1,000, which was already the maximum production capacity of the robot factory.

The next day, the number doubled to 2,000 units.

On the third day, four thousand units.

On the fourth day, 8,000 units.

The number of robots is rising almost exponentially online.

The newly assembled robot immediately loaded the energy module, which is a spirit stone energy conversion core, and immediately went to work.

Now, what limits the further increase in the number of robots is no longer the production of robot bodies, but the number of energy core reserves inside them.

Fortunately, the talisman array in the energy core is not that complicated. After laser engraving, it is activated by a disciple who has entered the Qi refining stage.

A disciple in the Qi refining stage can activate a thousand such talisman formations in one day. There are more than thirty disciples in the Qi refining stage in the base, and they can only activate more than 30,000.

Therefore, this balance was directly broken on the sixth day. The talisman array was no longer enough to meet Xiao Ai's production needs, so the gut-breaking robots were neatly placed inside the workshop, waiting for energy. After the module is filled, it is put into use.

Fortunately, at this time, most of the mining sites on the moon have been occupied by Xiaoai, and solar panels have begun to be laid in preparation for the next step of mining. All robot miners do not need to be in place at once, they can be filled slowly. .

At the same time, much more than that was being built. Not far from the base, excavators and bulldozers began to level the land again. Smoke and dust flew up and fell all over the sky, covering the Moon Palace with a thin layer of lunar soil.

This will be a large industrial area, with a spaceship area not far ahead.

In the future, more than a dozen large platforms on Mars will heat the planet by reflecting sunlight and increase its gravity, as well as the interstellar spacecraft docking area. All components will be produced here.

These large platforms may also be responsible for part of the work of space raw material processing in the future. After all, after the transformation of Mars is completed in the future, except for those biomaterials that can be recycled, the mining of its own minerals will obviously be minimized.

After all, it is a planet that has gained weight with great effort, so we can’t dig it up again, right?

The spacecraft area produces small spacecraft that can tow asteroids.

In order to take into account the quality of the spacecraft and the minerals of the moon, the hulls and main components of these spacecraft will be made of iron alloy.

After countless tests, an iron alloy that could withstand temperatures close to absolute zero was applied to the outer hull of the spacecraft.

Although the strength of titanium alloy is comparable to steel, this new iron alloy formula, for the first time, leaves titanium alloy far behind in terms of strength.

The reason why titanium alloy is important in aerospace is that it is light enough, which is indeed a huge advantage for traditional rocket engines.

However, in the face of gravity engines and fusion reactors with nearly unlimited energy, this advantage has disappeared.

Although even in space, small-mass spaceships have the advantage of maneuverability or fuel saving, this advantage has no greater significance within the solar system.

The lunar soil dug up by the forklift will be immediately sent to the collection room for high-temperature distillation.

The helium-3, water, and certain easily decomposable minerals inside will be collected separately during the high-temperature distillation process.

In the future, helium-3 will be concentrated and the water will be electrolyzed. A small amount of tritium and 20% of deuterium will be liquefied separately and used as nuclear raw materials.

According to Xiao Ai's estimates, the base is preparing to produce more than 10,000 spacecraft this time, and the nuclear materials required are also massive.

After all, in order to tow asteroids, their reactors are very large, with two 10 million kilowatt fusion reactors.

When an empty ship goes to the asteroid belt, it is enough to turn on one reactor, but when towing, two reactors must work together.
