The time became extraordinarily long in the wait, until Ye Han and the others returned to the living module, the satellite still did not jump out of the crater, until dinner, the communication equipment received the satellite signal and sent out a long sound of "beep". Pen, fun, and www.biquge.info

Gao Kai almost immediately rushed to the communication desk: "Call the command center at the temporary base, please answer if you receive it!" ”

More than a second later, a slightly distorted voice appeared: "Command center received, base, please speak!" ”

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

Huo Qiang happened to be in the command center, and after hearing the news, he switched lines and communicated with the lunar base in person: "Base, how many samples have you taken?" ”

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

"Twelve!" Gao Kai hurriedly replied.

"How many point samples?"

Gao Kai couldn't help but hesitate: "One, one." "The three groups of ice mining are not rushing to the heavy water at all, of course, they are taking ice in one location.

"How can one point work?" Huo Qiang questioned, "At the very least, we should find a few more points to determine the specific reserves and then report, right?" ”

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

"It's not bad for a while, it's too late today, I'll arrange it tomorrow, but don't affect the 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 it." ”

"You can arrange the specific situation, I just need the result."

"Okay." Ye Han nodded.

The time was almost up, and Gao Kai didn't talk much nonsense, and took his people out of the living cabin to take over.

Ye Han called Duan Zhiyang and Xu Hua to find out the aerial map of the crater, first draw the location of the temporary base, and then mark the location of today's water extraction, stared at the map for a while and said: "Let's take the location of today's ice as the starting point, every twenty 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'll see it!" Duan Zhiyang said.

"That's it!" Xu Hua said.

At the end of the 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 to turn 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 had just recorded and restarted the recording: "Xiaoting, I'm fine now, I just miss you very much......"

Bai Xiaoting felt irrepressible distress when she saw the video, although Ye Han didn't say it, she could see that Ye Han was very tired, not physically tired, but mentally tired.

After breakfast the next day, the three groups found yesterday's ice point, Ye Han walked ten meters east and then began to take ice, not only on the surface, but also at a depth of one meter and two meters respectively, and each ice sample was marked to avoid confusion.

The next three people were divided into three ways, Ye Han was responsible for taking ice and loading the truck, Duan Zhiyang was responsible for transporting and loading the truck, and Xu Hua was responsible for ice melting detection and unloading.

Although taking three copies at a point can make the data more accurate, the workload when taking the ice is also increased several times, although Ye Han tried his best, the speed is still unsatisfactory, and the excess ice has to be thrown aside temporarily, but this ice will not be wasted, it will be great to pull it back to the base after a while.

After a whole day of busy work, only 11 points of sampling were completed, and only two-thirds of the ice samples were tested.

There was too much melted water, the storage tank of the treatment tank was limited, and the electrolytic cell worked non-stop for a day, not only filling all the oxygen storage containers, but also creating more than 20 pieces of oxygen ice.

By the time we returned to the dormitory, everyone was tired, but the day's work was worth it, and although only 11 sampling points were measured, the results showed that there was no difference between the surface of the glacial lake and the ice samples at a depth of one or two meters.

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

For a crater with a diameter of more than 30 kilometers, there are more than 3,000 sampling points in a straight line from east to west every 10 meters.

He couldn't count it if he didn't calculate it carefully, anyway, he couldn't stop it if he wanted to do it.

Thinking of this, Ye Hanban's mouth was full of bitterness, a point of ten meters is too close, even if an ice sample is collected in a hundred meters, the workload is amazing, although the closer the sampling distance, the more accurate the survey results, but what is the point of getting the survey data after a few months or even years?

The longer it drags on, the more passive it becomes.

Ye Han gritted his teeth secretly, if he can't do it, he will take a point every kilometer, and then talk about it when he gets the analysis results.

With his mind made up, Ye Han finally fell asleep.

The investigation entered the third day, and the experience of the first two days made Ye Han smart, only one point of each ice sample was taken, enough to analyze the components, so that it only took a few minutes to melt an ice sample, and it only took two or three minutes to analyze a water sample, and it only took seven or eight minutes from the ice sample to the analysis results.

On the fifth day of the investigation, Ye Han had just cut through the ice when he was sampling, and a white mist suddenly rushed out of the ice cracks, so startled that he quickly jumped away, staring at the gushing fog in disbelief.

The mist rushed up to the sky more than ten meters high, and soon fell like snowflakes, accumulating a thin layer near the ice crevices.

What's going on?

Ye Han was confused, hesitated, leaned over and continued 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 below was particularly transparent, and the quality of the water ice was amazingly high.

Curious to take a closer look at the ice, under the light of his headlamp, he suddenly noticed that there was a hollow the size of a melon under the crack of the ice, and those snowflake-like things must have been spewing out from here!

Not only that, there were other cavities of different sizes under the ice, Ye Han was curious, so he simply continued to cut down, and after a while, he cut out a piece of ice with cavities.

As a result, he was shocked that the cavity of the ice cube actually contained a half-cavity of flowing colorless liquid!

The discovery was incredible, he had only heard of something called blisters in chalcedony, with natural watery cavities inside. The situation is similar for this piece of ice. The problem is that this is the surface of the moon at more than minus 200 degrees Celsius, and the only thing that can keep flowing under such extremely low temperatures seems to be liquid gas.
