Don’t think that Mars is a safe place, it’s even more dangerous near Mars!
In the Earth's low-Earth orbit, space walks are commonplace, but no matter what level of space orbit, they are protected by 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 expedition fleet, high-energy particles are the second biggest threat after aliens. Only the reinforced shell of the battleship 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 better. 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 material. Some heavy ions that have lost their extranuclear electrons will fly into deep space at a speed close to the speed of light. These heavy ions can easily penetrate the human body and break the cells in the cells.
DNA, even if you don't feel anything at the time, you will become seriously ill or even die from it afterwards.
Moreover, this thing cannot be discovered or predicted. In order to resist heavy ions, the two spacecraft have to block the engineering boat at all times.
Heavy ions are only one direction of danger, and the ubiquitous space dust also threatens the safety of the team members at all times!
Firstly, Ye Han didn't know much about the situation in this area. Secondly, he was so focused on the task that he didn't pay attention to this situation at all. As a result, an accident happened on October 9th, three days after the start of the project.
ACCIDENT.
That afternoon, the No. 3 engineering boat was under construction at the designated location. Several team members in the boat were in their respective positions. Everything was no different from before.
Several team members suddenly heard a crisp "bang" sound, and one team member screamed. A small hole was pierced in the armor of the torso, and blood gushed out like a fountain.
The air in the boat was rapidly lost amidst the weakening hissing sound, and the flying blood beads floated upward with the air. Several team members immediately found the location of the hole and immediately blocked it with air-tight plugs.
The air pressure immediately rose, but several team members ignored this and immediately rushed to the injured comrade. As a result, they found that the injured man's liver had penetrated and he had fallen into a coma.
The situation was urgent, and the team members had no time to contact the Luzhou, so they immediately gave the wounded a shot of hibernating hormone, and then sent the seriously injured comrades back to the spacecraft as quickly as possible.
Due to timely treatment, the wounded man finally saved his life, but the removal of one-fifth of the mangled liver not only required long-term recuperation, but also made him unfit to remain in the Marine Corps.
At Ye Han's insistence, all engineering boats stopped construction, and a comprehensive inspection was conducted on the No. 3 engineering boat. The investigation found that the culprit was just a piece of gravel the size of a finger.
Although the size of the gravel is small, its hardness is very strong, and the relative speed with Deimos is extremely high. It also happened to hit the engineering boat, so it first penetrated the engineering boat and then the power.
Armor, and an accident that injured a team member.
What makes Ye Han even more unbearable is that the investigation found that this piece of gravel actually came from Deimos!
In other words, the debris generated by drilling a few days ago turned around and smashed through the engineering boat. Ye Han didn't know what kind of coincidence there was, but he strongly requested that the soldiers' protection be strengthened and it must not happen again.
Same accident.
Xu Moliang strongly opposed it, believing that this was just an accident, and the probability could not be smaller. Even if everyone stood on Deimos openly, the same situation would not happen again, and there was no need to stop work and affect the progress.
But Ye Han believes 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 the person can be saved.
The team members are risking their lives for construction. If safety is not effectively guaranteed, how can they complete the project on time?
Ye Han took the weight and became determined. Faced with the strong Ye Han, Xu Moliang had to compromise. He spent a day dismantling a batch of armored plate reinforcement engineering boats from the Luzhou, and the engineering boats resumed work one after another.
As time went by, the team members became more and more proficient, and the errors in the underground wells became smaller and smaller. After half a month, the soldiers finally drilled the first underground well without deviation, and the drilling project entered the fast lane.
, underground wells hundreds of meters or even thousands of meters deep were completed one by one.
There were also some minor problems during this period, and equipment failures were commonplace. Once, a drilling rig malfunctioned, and the drill bit got stuck in the ground more than 70 meters deep. As a result, the drilling rig twisted the drill pipe, and the broken drill pipe bounced off the engineering boat and flew away.
It collided with the Luzhou again in the air, and ended up flying to nowhere.
Another time, the fixing device of the engineering boat failed. After starting, the drilling rig did not drill into the ground, but almost overturned the engineering boat.
There were also many other large and small faults, but fortunately they were not major problems. In addition, the Luzhou had enough spare parts, so the engineering boat could be repaired in the shortest time every time, and it 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 all laughed at themselves and said that they would get pregnant if they did not touch the gunmen for so long. If they stopped fighting in the future, they could make a fortune by digging wells at home.
Although the words were meant as a joke, the actual situation was similar. The Marine Corps completely transformed into an engineering team and thoroughly understood all the drilling procedures.
Of course, this technology can also be used on Deimos. The gravity here is so low that it can be ignored. No matter how much the underground well is dug, there is no danger of collapse. Even if the satellite is penetrated, it will not be a problem.
In this way, Ye Han led his team members to be busy for more than a month, and finally completed all the underground wells on Deimos in early November. The irregular underground wells almost turned Deimos into a super honeycomb. As long as the nuclear bomb is sent
Enter the underground well and wait for Jupiter slowly.
Although there are a large number of underground wells, only a small part of them need to be placed for nuclear bomb blasting. The reason why so many underground wells are drilled is to shape the "munitions"!
When Ye Han first learned about this, he was completely confused. He didn't understand what the relationship between underground wells and shaping was. After listening to Xu Moliang's explanation, he understood that many underground wells formed a weak separation layer around the "ammunition".
, the blasting separation layer is destroyed first, so that the appearance of the "munition" can be maintained to the maximum extent, and the ammunition can be prevented from being shattered by the nuclear explosion to the greatest extent.
The project on Deimos is over, and the project on Phobos is about to begin.
