That night, at around 8 p.m. Earth time, the shuttle returned to Hope, carrying the asteroid meteorite that had been broken down and analyzed.

Of course, the asteroid meteorite is sealed by various means to prevent it from coming into contact with the air of Hope, because after all, the shuttle is just a simple laboratory, and many more in-depth experiments need to be carried out on Hope, and in order to prevent accidents, there is one last experimental step to confirm that these asteroid meteorites are 100% safe!

Of course, as the captain and supreme leader of the Hope, Yao Yuan must also be present, talking to those staff members, shaking hands and thanking them, etc., these are essential, and it can't be said to be a show, because Yao Yuan is also sincerely grateful to them, after all, there are so many situations in the universe, who knows if those meteorites are safe? These people also went with some kind of consciousness, so even in front of others, Yao Yuan had to thank them.

Then, there are the sharp laboratories of the fourth and fifth layers of the Hope, which analyzed the asteroid meteorite material, all aspects, through chemical, physical, biological, all aspects of analysis and experiments, almost all scientists are busy all night, no one feels bitter, in fact, many scientists are so excited that they want to spray nosebleeds, extraterrestrial matter, and they are mining alien material, according to the development of human beings on the earth, at least until the beginning of the twenty-second century, Or maybe it will be possible by the end of the twenty-first century, but they have already done it now.

It was so busy that by the next morning, the composition analysis of the meteorite had been completely completed, and all the data was written as a report file and concentrated in Yao Yuan's captain's room.

Yao Yuan looked at these reports carefully, since he left the earth, he is not idle every day, in addition to his daily fixed work, the rest of the time he is basically absorbing all kinds of knowledge, not seeking depth, first improving the breadth of each aspect of knowledge.

In fact, Yao Yuan is quite glad that the preparations before leaving the earth, not to mention the materials or anything, the key is a large number of scientists and a large number of technical workers, engineers from various industries, and from the desert planet, to the nebula material area, and now to see the hope, when the universe can be mined, it is these scientists, technical workers, and engineers who play the biggest role on the Hope, they are really worthy of the elite of the human elite, and they can afford this name.

According to their report, the asteroid meteorite confirmed that there were no viruses, microorganisms, or other life reactions, including possible silicon-based life, which were not present.

Secondly, the composition of asteroid meteorites contains many substances, metallic and mineral, but they are basically compounds or oxides, but they only need energy, and they can still be completely purified by electrolysis and chemical means, or smelting methods.

Of course, according to the inference of scientists, the asteroid belt here is too fragmented in size in terms of minerals and meteorites, not to mention not conducive to collection, and there are not many minerals in it, a large number of which are silica, that is, sand rocks, which are basically of little use to Hope except for extracting oxygen and forming oxygen.

In comparison, on the other side of the two-month space distance from Hope, the terrestrial planet that is in the early stage of formation, the asteroid material there is very huge, the largest piece has become the core of this terrestrial planet, its size is almost comparable to a small moon, and its mass and gravity are definitely greater than the surrounding asteroid fragments, so as to be able to absorb and condense the surrounding materials, so the largest asteroid must be rich in minerals and various substances, especially the radioactive elements must also be enriched. This is the substance that the Hope needs most.

Yao Yuan finished reading the report in his hand, and he pondered.

In the report, the scientists were divided into two groups, one group believed that they should immediately set sail for the terrestrial planet that was forming, the largest asteroid fragment was large enough to land Hope, and the meteorites there were generally very large, suitable for collecting the richest parts of it and obtaining large quantities of minerals and radioactive ores.

The other school of thought believes that no one knows what dangers are in the universe, and maybe there will be a new crisis in the next moment, so instead of spending two months sailing over, it is better to collect enough radioactive minerals here, and also replenish the water and oxygen on the Hope, as well as other compounds, at least need to replenish the radioactive minerals that can jump two or three times, and then go to that terrestrial planet to excavate, which is the safest way.

Both have their own reasons, but the second, that is, the theory that some of the materials were collected here first, has won the support of more than seventy percent of scientists, and even Yao Yuan agrees with this.

However, the second opinion has a fatal flaw, that is, it is impossible for Hope to get close to the asteroid belt, to prevent asteroid random collisions, there will be an asteroid that will break away from hit Hope, in fact, the current distance of 50 kilometers has made some scientists warn, according to them, 100 kilometers to 200 kilometers range, this is a safe area.

Because of this, it was impossible for the Hope to go up to collect it in person, so it would have to send a small spacecraft such as a shuttle to collect it.

But at present, there is a key problem that there is only one shuttle in the Hope at present, even if it is collected 24 hours a day, this is not digging the ground, but the collection of minerals in the universe, you need to choose the size of the asteroid meteorite, select its appearance color, in order to preliminarily judge its composition, try to choose the most minerals, and its capacity is also limited, and so on, a shuttle is simply impossible to bear the consumption of the entire Hope, and it will take at least ** months when the collection is completed, And in these years, a lot of material ...... has been consumed+.

"Isn't there only the first option? Go to a terrestrial planet, land on a large asteroid debris, and collect it the traditional way? Yao Yuan rubbed his brow a little distressedly.

As he looked at some of the documents in his hand, he suddenly found one of them, and the author of this document was Polly, the only healthy whisperer on the Hope...... Ivan is still in the hospital care unit, the severe burns will be completely recovered, it is estimated that the growth of the genetically modified pig will stop, and the skin of the genetically modified pig can be transplanted to Ivan, which is cultivated according to his genes This genetically modified pig, which is the technology after 2020, is just used here.

On the Polly document, it is proposed to create a simple mineral collection spaceship, the size is only about one-fifteenth of the shuttle, the interior generally sits two to three people, has a simple contact device, an ordinary propulsion system, a two-to-three-person life support system, can be away from the ship for four to five hours, there is no mineral storage device, this ultra-small spacecraft only has a pair of mechanical arms, it is very simple to build, after people sit in, they can fly to the asteroid belt with a small spaceship, and then select five to ten cubic meters of asteroid meteorites, Then use the robotic arm to bring it back to Hope, and this is the collection......

Yao Yuan carefully looked at the design plan on this document, this kind of small mining spaceship is indeed very small, the bulkhead is also very thin, it cannot be compared with the shuttle at all, and the internal device is also very simple, a set of liaison devices, ordinary propulsion system and engine, two to three people life support system, no anti-gravity system, no various complex instruments, to be precise, this kind of small spaceship is not so much a spaceship, but a fully enclosed car, but more propulsion systems to accelerate and decelerate, Add in the Vitamin's system to keep the oxygen, temperature, pressure inside the boat, and other than that, it's really no different.

However, the cost of this small spaceship is extremely low, it almost does not consume much things, and there is no high-tech content, according to the data and calculation formulas listed by Polly, the smelting room, parts room, modification room, plus those skilled workers and engineers can build about five to seven ships a day, and with the proficiency and future transformation, it may be possible to build ten ships a day.

"If feasible......"

Yao Yuan did what he thought of, and dozens of minutes later, he saw Polly in a laboratory calculating something.

This is a girl who is always expressionless, delicate and beautiful, but never dressed up, and her hair is a little messy, when Yao Yuan proposed to see the model of this mineral gathering spaceship, Polly directly spread his hands and said: "It's exploded." ”

"Exploded? What do you mean? Yao Yuan asked a little inexplicably.

"It's just bursting." Polly looked back even more inexplicably, as if she was looking at a stupid person, she pressed something on her computer, and soon, a set of analog images appeared on the screen.

Yao Yuan saw that the simulated mining spaceship left the Hope and flew towards the asteroid belt, halfway through, the engine suddenly sparked, and then soon, the entire mining spaceship exploded in space, directly turned into a spark, and the most important thing is that at the end of this simulation screen, there was actually a gameover picture, which made Yao Yuan's head full of cold sweat.

"The engine of the mining spaceship cannot use the kind of shuttle, because the size is different, the energy required is different, and the energy that can be loaded is also different, which requires urgent research and special manufacturing, and it is impossible to solve the engine problem in the short term with my ability alone." Polly said calmly.

Yao Yuan was already completely disappointed and was about to leave now, but when he heard this, he immediately asked excitedly, "Is it?" With our current technology, can we build such a scaled-down space engine? ”

"Of course." Polly glanced at him and said lightly: "My design is fine, the key is that the engine needs to be specially manufactured, otherwise ......"

Yao Yuan laughed and patted Polly's little head directly, causing Polly to look at him again, but he didn't care, and left the laboratory with a laugh.

In the afternoon of the same day, engineers and scientists from various related specialties were gathered, and Yao Yuan proposed a plan for a small mining machine and put forward the research situation of related engines......

Three days later, this new scaled-down engine was built, and the relevant personnel were given a reward of 50 to 100 yuan in human coins, and Bo Li, as the designer, directly issued 250 human coins, and then, the prototype of the first mining machine was built.

"Two hundred and fifty ......"

Polly looked at the information on the screen about the arrival of the new transfer in the magnetic card, she sneered, and a bruise appeared faintly on the door of her head.

"Hmph, now that you know my identity, you don't need to tell me deliberately......"

"I'm like two hundred and five there! You idiot is two hundred and five! ”
