That night, around 8 pm Earth time, the shuttle returned to Hope, carrying the asteroid meteorite that had been decomposed and analyzed.

Of course, asteroid meteorites are closed by various means to prevent them from being exposed to 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. In case of prevention, there is also a last experimental step to confirm that these asteroid meteorites are 100% safe!

Of course, as the captain of Hope and the supreme leader, Yao Yuan must also be present. Talking and sympathizing with the staff, shaking hands and thanking them, etc., these are essential. They cannot 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 whether those meteorites are safe? These people also left with some awareness, so even in front of others, Yao Yuan must thank them.

Then, the sharp laboratories on the fourth and fifth floors of Hope analyzed the asteroid meteorite matter in all aspects, through chemical, physical, biological, and various analysis and experiments, almost all scientists were busy all night, and no one felt bitter. In fact, many scientists were so excited that they were bleeding from the nose. They were also mining alien matter. According to the development of human beings on Earth, it would not be possible until at least the early 22nd century or the end of the 21st century, but they had done it now.

It was so busy that by the next morning, the composition analysis of the meteorite had been thoroughly done, and all the data was written into report documents, which were concentrated in Yao Yuan's captain's room.

Yao Yuan looked at these reports carefully. Since he left the earth, he has not been idle every day. Apart from his regular work every day, he has been absorbing all kinds of knowledge for the rest of his time. He does not seek depth, but first improves the breadth of each knowledge.

In fact, Yao Yuan was very grateful for the preparations before leaving the earth, not to mention materials, the key was a large number of scientists, a large number of technical workers, engineers from various industries. From the desert planet, to the later nebula material areas, and now seeing hope, when mining in the universe, these scientists, technical workers, and engineers played the greatest role on Hope. They are truly the elites among human elites and can fully afford this title.

According to their report, there are no viruses, microorganisms or other life reactions in the asteroid meteorites, including possible silicon-based life, that do not exist.

Secondly, the components of asteroid meteorites contain many substances, metals, and minerals, but they are basically compounds or oxides, but only energy is required. Through electrolysis, chemical means, or smelting means, they can be completely purified easily.

Of course, according to scientists' inferences, the minerals and meteorite sizes here are too broken, not only not easy to collect, but there are not many minerals in them, and a large number are silica, that is, sand and rocks. These things are basically of little use for Hope, except for extracting oxygen elements and forming oxygen.

In comparison, on the other side of the two months away from Hope's space, the asteroid planet that was forming in the early stages, the asteroid matter there is very huge. The largest piece has become the core of this terrestrial planet, and its size is almost as large as a small moon. Moreover, its mass and gravity are definitely larger than the surrounding asteroid fragments, so that the surrounding matter can be absorbed and condensed. Therefore, the largest asteroid must be rich in minerals and various substances, especially radioactive elements, which are definitely rich in substances. This is the most insecurity and need of Hope.

After Yao Yuan read the report sheet in his hand, he began to ponder.

On the report list, scientists were divided into two factions. One thought that it should set sail immediately to the land-like planet that was forming. The largest asteroid fragment was even large enough to allow Hope to land. Moreover, the meteorites there were generally very large, suitable for collecting the richest parts of it and obtaining a large number of minerals and radioactive minerals.

Another faction believes that no one knows what dangers are in the universe, and may a new crisis occur in the next moment. So instead of spending two months on sailing, it is better to collect enough radioactive minerals here first, and also supplement the water and oxygen on Hope, as well as other compounds. At least it is necessary to supplement radioactive minerals that can jump two to three times before going to the Earth-like planet for excavation. This is the safest way.

Both have their own reasons, but the second one, that is, the statement that some materials were collected here first, won the support of more than 70% of scientists, and even Yao Yuan agreed with this.

However, the second opinion has a fatal flaw, that is, Hope cannot approach the asteroid belt, to prevent the asteroid from colliding randomly, and asteroids that will break out will cause apart from the collision of Hope. In fact, the current distance of 50 kilometers has caused some scientists to warn that according to their statement, a range of 100 kilometers to 200 kilometers is a safe zone.

Because of this, Hope cannot go up to collect it in person. In this way, it can only send small spacecraft such as shuttles to collect it.

But there is a key problem at present. Hope currently has only one shuttle. Even if it is collected for 24 hours a day, it is not digging ground, but mineral collection in the universe. It is necessary to select the size of asteroid meteorites and choose their appearance and color to determine their composition in a preliminary manner. Try to choose the ones with the most minerals, and their capacity is limited. In various situations, a shuttle can not afford the consumption of the entire Hope. It will take at least eight or nine months by the time the collection is completed, and a lot of material has been consumed...

"Can you only choose the first method? Go to a terrestrial planet, land on large asteroid fragments, and then collect them in the traditional way?" Yao Yuan rubbed his brows with some distress.

Just as he was looking at some documents in his hand, he suddenly found one of them. The author of this document was Poli, the only healthy whisperer on the Hope Number... Yifan is still in the hospital custody room. The severe burns need to be completely recovered. It is estimated that the genetically modified pig will have to wait until the genetically modified pig grows to Yifan. The genetically modified pig's skin can be transplanted to Yifan. This is the technology after 2020 and is used here.

In Boli's document, it proposed to make a simple mineral collection spacecraft, which is only about one-fifth of the size of a shuttle. It usually sits two to three people inside, with a simple liaison device, an ordinary propulsion system, and a two to three person life maintenance system. It can be lived for four to five hours away from the ship. There is no mineral storage device. This ultra-small spacecraft has only a pair of robotic arms, which is very simple to build. After people sit in, they can fly to the asteroid belt by driving the small spacecraft, and then select five to ten cubic meters of asteroid meteorites, and then use the robotic arm to bring them back to Hope. This is the collection...

Yao Yuan looked carefully at the design plan in this document. This kind of mining spacecraft is indeed very small, and its bulkhead is also very thin, which is completely incomparable to the shuttle. The internal device is also very simple. A set of contact devices, ordinary propulsion systems and engines, two to three-person life maintenance systems, no anti-gravity system, and no various complex instruments. To be precise, this small spacecraft is more of a fully enclosed car than a spacecraft, but there are more propulsion systems from front, back, left and right to accelerate and decelerate, and a life maintenance system to maintain the oxygen, temperature, pressure and other things in the ship. Apart from this, there is really no difference.

However, this small spacecraft is extremely costly, consumes almost no amount of things, and has no high-tech content. According to the data and calculation formulas listed by Poli, the smelting room, parts room, modification room of Hope, plus those skilled workers and engineers, can make about five to seven ships a day. And with the proficiency and future transformation, it may be possible to have ten ships a day.

“If possible…”

Yao Yuan did it when he thought of it. After a few dozen minutes, he saw Boli, who was calculating something in a laboratory.

This is a girl who always has no expressions. She looks pretty and beautiful, but never dresses up, and her hair feels a little messy. When Yao Yuan proposed to see a model of this mineral collection spacecraft, Boli spread her hands and said, "It's explosive."

"It's exploded? What does it mean?" Yao Yuan asked inexplicably.

"It's just exploded." Poli looked back inexplicably, and her eyes seemed to be looking at a fool. She was pressing something on her computer. Soon, a set of simulated images appeared on the screen.

Yao Yuan saw the simulated mining spacecraft leaving Hope and taking it toward the asteroid. Halfway through the flight, the engine suddenly sparked, and soon, the entire mining spacecraft exploded into the universe and turned into a spark. The most important thing is that at the end of the simulation screen, a gameover actually appeared, which made Yao Yuan's head full of cold sweat.

"The engine of the mining spacecraft cannot be used as a shuttle, because the size and energy required are different, and the energy it can be loaded is also different. This requires urgent research and special manufacturing. With my own ability, it is impossible to solve this engine problem in the short term." Poli said frankly.

Yao Yuan was completely disappointed and planned to leave. When he heard this, he immediately asked excitedly: "Is that so? With our existing technology, can we create such a reduced space navigation engine?"

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

Yao Yuan laughed loudly and patted Boli's little head, which caused Boli to roll his eyes and look over again. He didn't care and left the laboratory with a laugh.

In the afternoon of the same day, engineers and scientists from various related majors were gathered together. Yao Yuan proposed a plan for a small mining machine and proposed the research on relevant engines...

Three days later, this new reduced version of the engine was manufactured, and the relevant personnel issued a bonus of 50 to 100 yuan in human coin, while as the designer, Boli directly issued 250 yuan in human coin, and then the trial production of the first mining machine was manufactured.

"Two hundred and fifty..."

Poli looked at the information about the arrival of new transfers on the magnetic card on the screen, and she sneered, and blue veins appeared on her forehead.

"Hmph, if you know my identity, there is no need to tell me on purpose..."

"I'm like two hundred and five! You idiot are two hundred and five!"
