Armor Frenzy

The time became extraordinarily long during the waiting. Until Ye Han and others returned to the living cabin, the satellite had not yet jumped out of the crater. It was not until dinner time that the communication equipment received the satellite signal and issued a long beep.

Gao Kai rushed to the communication station almost immediately: "The temporary base calls the command center, please answer when you receive it!"

After more than a second, a slightly distorted voice appeared: "The command center received it, the base please speak!"

"The command center, the base mines water ice, and the heavy water content is 0.6%..." Gao Kai briefly reported the situation, and finally asked for instructions on what to do next.

Huo Qiang happened to be at the command center. After hearing the news, he switched the line and communicated with the lunar base in person: "Base, how many samples did you take?"

Gao Kai immediately asked with his eyes, and Ye Han answered with his mouth: "Twelve copies."

"Twelve copies!" Gao Kai quickly replied.

"How many points to sample?"

Gao Kai couldn't help hesitating: "One, one." The three groups of ice picking did not go to heavy water at all, of course, they were picking ice from one location.

"How about one point?" Huo Qiang questioned, "At least we need to find a few more points to confirm the specific reserves and report back?"

"Yes, I was negligent, arrange sampling immediately!"

"It's not too late, it's too late today, we'll make arrangements tomorrow, but don't interfere with normal work." Huo Qiang instructed.

"Yes!"

At the end of the communication, Gao Kai sighed: "Ye Han, did you hear it?"

Ye Han nodded: "I heard."

"You can arrange it yourself, I just want the result."

"Okay." Ye Han nodded.

The time was almost up, Gao Kai didn't talk too much, and the people who brought him left the living cabin to take over.

Ye Han called Duan Zhiyang and Xu Hua to find out the aerial map of the crater. First, he drew the location of the temporary base, then marked the location of today's water intake. He stared at the map for a while and said, "Let's take ice today. The location is the origin, every 20 meters... No, take a sample every 10 meters, record the sampling location in detail, and then study the next step after getting the results."

"I see it!" Duan Zhiyang said.

"Just do it!" Xu Hua said.

After a day's work, Ye Han finally returned to the narrow nest. While the satellite was still in the sky, he took out his mobile phone and turned on the video function, and put it on the small table to face his face, but he didn't know what to say. .

After hesitating for a while, he deleted the video he just recorded and started recording again: "Xiaoting, I'm fine now, I just miss you so much..."

Bai Xiaoting felt uncontrollably distressed when she saw the video. Although Ye Han didn't say anything, she could see that Ye Han was very tired, not physically, but in her heart.

After breakfast the next day, the three groups found yesterday's freezing point. Ye Han started to take ice after walking ten meters to the east, not only taking samples on the surface, but also taking samples at a depth of one meter and two meters. Good markup to avoid confusion.

The next three were divided into three groups. Ye Han was in charge of fetching and loading ice, Duan Zhiyang was in charge of transporting, loading and unloading, and Xu Hua was in charge of ice melting detection and unloading. The three cooperated with each other to investigate the heavy water content as quickly as possible.

Although taking three copies at a time can make the data more accurate, the workload when taking ice also increases several times. Although Ye Han tried his best, the speed is still unsatisfactory. The extra ice has to be temporarily thrown aside, but these ice It won't be wasted, it's great to pull it back to the base after a while.

After a whole day of busy work, only eleven points of sampling were completed, and only two-thirds of the ice samples were tested. In order not to hinder the progress of the investigation, the three of them had dinner and continued to work until midnight. Sample.

There was too much melted water and the capacity of the water storage tank in the treatment cabin was limited. The electrolytic cell worked continuously for a day, not only filling all the oxygen storage containers, but also making more than 20 pieces of oxygen ice.

When we returned to the dormitory, everyone was very tired, but the hard work of the day was worth it. Although only the data of eleven sampling points were measured, the test results showed that the surface of the ice lake was one meter deep and two meters deep. There is no difference in the content of ice samples.

After getting the comparative data, Ye Han decided to revise the investigation plan and only collect surface ice samples for testing, which can greatly speed up the investigation progress.

The crater with a diameter of more than 30 kilometers has more than 3,000 sampling points every 10 meters and a straight line from east to west. If the entire lake area is checked, how many ice samples should be collected?

He couldn't figure it out if he didn't calculate it carefully. Anyway, he couldn't stop it.

Thinking of this, Ye Han's mouth is full of bitterness. A point of ten meters is too close. Even if an ice sample is collected at a hundred meters, the workload is astonishing. Although the closer the sampling distance is, the more accurate the survey results will be. What's the point of getting survey data months or even years?

The longer you drag on, the more passive you become.

Ye Han gritted his teeth secretly. If he couldn't do it, just take a point a thousand meters and get the analysis results.

Determined, Ye Han finally fell asleep.

The investigation entered the third day. The experience of the first two days made Ye Han learn to be smart. Only take a little of each ice sample, enough to analyze the components. In this way, it only takes a few minutes to melt an ice sample and analyze a water sample. In two or three minutes, it only took seven or eight minutes from the time the ice sample began to melt to the analysis result.

On the fifth day of the investigation, Ye Han had just cut open the ice surface when taking samples, when a white mist suddenly burst out from the cracks in the ice. He was so shocked that he quickly jumped away and stared at the gushing mist in surprise.

The fog rushed into the sky more than ten meters high, and soon fell down like snowflakes~www.readwn.com~ A thin layer was deposited near the ice crevice.

what's going on?

Ye Han was completely confused, hesitated for a moment, leaned over to continue cutting, and quickly took off a half-meter square ice sample. He unexpectedly found that only the surface of the ice layer was covered with a layer of dust, and the ice layer below was very special. Transparent, the water ice quality is surprisingly high.

Curiously observing the ice body carefully, under the light of the headlamp, he suddenly found a melon-sized hole under the crack of the ice. Those snowflake-like things must have spewed out from here!

Not only that, but there are other cavities of different sizes under the ice. Ye Han was curious and simply continued to cut down. After a while, an ice cube with a cavity inside was cut out.

The result surprised him, the cavity of the ice cube actually contained a half-cavity of colorless liquid!

This discovery was incredible. He had only heard of a kind of thing called blisters in chalcedony, which had natural water-containing cavities inside. This ice is in a similar situation. The problem is that this is the surface of the moon at minus 200 degrees, and it seems that only liquid gas can keep flowing at this extreme low temperature.
