Eight Hundred and Sixtieth IX Earth Drilling Engineering (2)

Don't think that Mars is a safe place, it is even more dangerous near Mars!

In the Earth's low-Earth orbit, spacewalking is nothing more than a common thing, but no matter what level of space orbit, it is under the protection of the Earth's magnetic field, which can effectively resist high-energy particles from the sun and the depths of the universe.

Mars is different. Its magnetic field disappeared billions of years ago. Only a small amount of magnetic field remains on the surface. Without a global magnetic field, it cannot resist high-energy particles from the sun and distant stars.

For the expeditionary fleet, high-energy particles are the second biggest threat after aliens. Only the shell of the battleship with added materials can block them. The thin shell of the engineering boat has a very limited effect. The power armor on the soldiers It's not much stronger, short-term off-ship work is not a big problem, but long-term off-ship activities are very dangerous.

To give a very simple example, a supernova explosion in the distant starry sky will eject a large amount of matter, and some heavy ions that have lost their extranuclear electrons fly to deep space at a speed close to the speed of light. These heavy ions can easily penetrate the human body and shatter the cells in the cells DNA, even if you don't feel it at the time, will get seriously ill afterwards, and even die because of it.

Moreover, this thing can neither be discovered nor predicted. In order to resist heavy ions, the two spaceships have to block above the engineering boat at all times.

Heavy ions are only one direction of danger, and the ubiquitous space dust is always threatening the safety of the team members!

Ye Han didn't know much about this aspect, and secondly, he was so focused on the task that he didn't pay attention to this aspect at all. As a result, an accident happened three days after the project started, that is, on October 9th. ACCIDENT.

That afternoon, engineering boat No. 3 was under construction at the designated location, and several team members in the boat took their positions, and everything was no different from before.

Several team members suddenly heard a crisp sound of "beep", a team member screamed, a small hole was pierced in the torso armor, and blood gushed out like a fountain.

The air in the boat was rapidly lost amidst the ever-decreasing hissing sound, and the flying blood beads floated upwards along with the air. Several team members immediately found the location of the hole, and immediately blocked the hole with an airtight plug.

The air pressure immediately picked up, but several team members didn't care about this, and immediately rushed to the injured comrade, only to find that the injured's liver had been punctured, and he had fallen into a coma.

The situation was urgent, and the team members had no time to contact the Luzhou, and immediately gave the wounded a shot of hibernation, and then sent the seriously injured comrades back to the spaceship as quickly as possible.

Because of the timely treatment, the wounded finally recovered his life, but the removal of one-fifth of the broken liver not only required long-term recuperation, but also made him unsuitable to stay in the Marine Corps.

Under Ye Han's insistence, all engineering boats stopped construction, and an all-round inspection was carried out on the No. 3 engineering boat. The investigation found that the culprit was just a finger-sized gravel.

Although the size of the gravel is small, its own hardness is very strong, and the relative speed between Deimos and Deimos is extremely high, and it happens to hit the engineering boat, so there is a phenomenon that first penetrates the engineering boat and then penetrates the power. armor, also injured a team member in an accident.

What made Ye Han even more unbearable was that the investigation found that this piece of rubble actually came from Deimos!

In other words, the rubble produced by the drilling a few days ago, turned around and smashed through the engineering boat. Ye Han didn't know what kind of coincidence was in it, but he strongly demanded that the soldiers' protection should be strengthened, and it must not appear again Same accident.

Xu Morian strongly objected, thinking that this was just a random accident, and the probability couldn't be more small. Even if everyone stood on Deimos openly, the same situation would not happen again, and there was no need to stop work to affect the progress.

But Ye Han thinks that if there is one, there are two. Xu Moliang's statement has no basis at all. If the same situation happens again, it is hard to say whether he can be rescued.

The team members are risking their lives for construction. If safety cannot be effectively guaranteed, how can they complete the project on time?

Ye Han ate the weight and became determined. Facing the strong Ye Han,

Xu Morliang had to compromise, and spent a day dismantling a batch of armored and reinforced engineering boats from the Luzhou, and the engineering boats resumed work one after another.

With the passage of time, the proficiency of the team members is getting higher and higher, and the error of the well is getting smaller and smaller. After half a month, the soldiers finally drilled the first well without deviation, and the drilling project has since entered the fast lane. , A series of wells with a depth of hundreds of meters or even thousands of meters were completed one by one.

There were also some minor problems during the period, and equipment failures were commonplace. Once a drilling rig malfunctioned, the drill bit was stuck in the ground at a depth of more than 70 meters. In the air, it collided with the Luzhou again, and finally flew to nowhere.

Another time, the fixing device of the engineering boat failed. After the drilling rig was started, it did not go underground, but almost overturned the engineering boat.

There were many other large and small faults, but luckily none of them were major faults. In addition, the Luzhou ship had sufficient spare parts, and the engineering boat could be repaired in the shortest time every time, which finally did not affect the progress of the project.

Although the soldiers complained constantly in private, when it was their turn to be on duty, they walked into the engineering boat without hesitation.

The team members laughed at themselves and said that if they didn't touch the guns for so long, they would give birth, and if they don't fight in the future, they can make a fortune when they go home and dig wells.

Although the words were teasing, the actual situation was similar. The Marine Corps completely turned into an engineering team and thoroughly understood all the drilling procedures.

Of course, this bit of technology can also be used on Deimos, where the gravity is so low that it can be ignored, no matter how the ground well is dug, there is no danger of landslides, even if the satellite is pierced across, it is not a problem.

In this way, Ye Han led his team members to be busy for more than a whole month, and finally completed all the wells on Deimos in early November. The messy wells almost turned Deimos into a super honeycomb. Enter the well and wait slowly for Io Zero.

Although there are many wells, only a small number of them need to be placed with nuclear bombs. The reason why so many wells are drilled is to shape the "ammunition"!

When Ye Han first found out about this, he was confused. He didn’t understand the relationship between wells and shaping. After listening to Xu Moliang’s explanation, he realized that many wells formed a weak separation layer around the “ammunition”. If the blasting separation layer is destroyed first, the appearance of the "ammunition" can be kept to the greatest extent, and the ammunition can be prevented from being broken by the nuclear explosion to the greatest extent.

The project on Deimos is finished, and the project on Phobos is about to start.
