"Let's get started." Wu Hao looked at the picture on the big screen and said immediately.
"Sampling begins." Immediately Shi Zhaoping gave the order.
As the command was issued, on the big screen, in the surveillance camera screen on the small detection robot, a small intelligent robotic arm replaced the sample drill bit and began drilling at a piece of crystal clear ice in front of it.
No sound can be heard in a vacuum, but the sound will be transmitted back through the robotic arm. There is a sound-collecting microphone on the small detection robot, so the slightest drilling sound can be heard.
The lens zoomed in and focused on the drill. It was seen that the drill was very sharp and drilled out many ice chips on the ice. The drill also continued to penetrate deeper, until it reached a depth of about fifteen centimeters, and then it stopped.
Then the small intelligent robotic arm replaced the sample shovel, carefully collected the ice chips coming out of the drill bit, sealed them, and put them into the sample storage box on the small detection robot.
This kind of sampling is far from over. Next, the small detection robot needs to take multiple samples of different ice cubes and different locations. In addition to drilling, the small detection robot also uses the impact hammer on the mechanical arm to break the ice cubes and then extract them from them.
Collected some ice cubes of different sizes.
In addition to these ice cubes, this small exploration robot also sampled lunar soil and lunar rocks from various landscapes at the bottom of the Moon Creek Valley.
After completing this, the small detection robot slowly drove out of the valley. When it first descended to the bottom of the Yuexi Valley, it used the relatively gentle slope on the Yuexi side, and then relied on the "Wangshu" intelligent lunar
The lunar surface inspection and exploration vehicle was pulled by cables and then slowly descended to the bottom of the valley. But if you want to go up this time, it will not be easy. If you use too much force and break the cables, the loss will be huge.
, this may affect the subsequent series of detection tasks.
Therefore, the small detection robot switched to a six-legged mode of travel and began to slowly crawl up the complex rock wall. In addition, the "Wangshu" intelligent lunar surface inspection and exploration vehicle had a smaller traction force on it, so
Although the terrain of the rock wall is complex, the small detection robot still climbed up little by little.
Although the cliff was only 50 to 60 meters long, it frightened the small detection robot for more than half an hour before it successfully climbed up the Moon Creek and met the "Wangshu" intelligent lunar surface parked on the edge of the Moon Creek.
The inspection rover conducts a meeting.
Although it has been determined that these crystal clear things are ice, no one can be sure without testing and analysis. Because there are too many things that can crystallize, such as crystals, methane, carbon dioxide, etc.
So now both Zhang Qutong and Zhang Jun are eager to conduct testing as soon as possible. Wu Hao, on the other hand, is not very eager. In his opinion, the samples have been taken out from the bottom of Yuexi Valley, so there is no need to wait.
time.
At this moment, many people gathered in the Xinyuehu Aerospace Command and Control Hall, and many people who had the authority to come here gathered in the hall. Everyone was eager to know whether the composition of these samples was water.
Under the watchful eyes of everyone, the small mechanical watch on the "Wangshu" intelligent lunar surface patrol and exploration vehicle took out a tube of samples from the sample storage box of the small detection robot. The tube containing the stored samples
It is a resin sampling storage tube about the size of an adult's index finger. This sampling storage tube is also specially customized for sampling. It can withstand a certain amount of pressure and can withstand the high and low temperature transitions of the moon and even the universe, and it is very durable.
Stable, it is a very ideal sample storage vessel. A lot of sample storage tubes like this are prepared on the "Wangshu" intelligent lunar surface patrol and exploration vehicle to facilitate sampling. In addition to this kind of sample storage tube, there is also a sample storage tube
Sealed bag for convenient sampling, storage and use.
When the high-definition lens was focused on the transparent sampling storage tube, everyone exclaimed and showed expressions of surprise.
The temperature of the moon's surface ranges from minus 180 degrees to plus 160 degrees. When the sun shines, it can reach plus 180 degrees. At this temperature, ice can melt instantly and even
boiling.
So when the transparent sampling storage tube saw sunlight, the originally solid ice slag inside actually melted into liquid at a very fast speed.
This is water, for real.
Everyone exclaimed in surprise.
Zhang Jun stared at the screen and said in dialect: "If this isn't water, I'll drink it all."
You are so beautiful, do you know how much it costs to ship this tube of samples back, and you can still drink it clean? Wu Hao joked with a smile.
Hehehehe...
The tense atmosphere at the scene also relaxed. Wu Hao smiled and nodded at Shi Zhaoping. Then under Shi Zhaoping's instruction, the transparent sampling storage tube was placed out of the experimental cabin door by a small intelligent robotic arm. Then the outer door of the experimental cabin opened.
The transparent sampling storage tube was moved into the preparation area inside the experimental cabin. The miniature intelligent robotic arm in the experimental cabin opened the sampling storage tube, then took out one or two drops of liquid from it, and then placed it on the test bench.
The two drops of liquid were dropped onto the test stand and quickly opened up, like two flowers spread out. Then, a high-power digital microscope began to observe the two drops of water stains. At the same time, the elemental analyzer also began to analyze and detect
stand up.
Soon, a high-definition, high-power microscope photo was returned from Chuanshui and displayed on the big screen.
An expert stared at the photo on the big screen and shouted excitedly: "This is water. Look, it is very pure. There is not even a single impurity in it."
What are those crystal particles? Someone asked.
"It should be salt, or sodium chloride crystal particles. It may be that the salt in the soil has dissolved into the water." An expert answered.
Is this water the same as that on the earth? Can it be mixed with it? Zhang Junwen came up with a question that everyone is concerned about. Although the analysis and test results have not yet come out, it is basically certain that it is water. But the water on the moon is different from the water on the earth.
Is it the same, and more importantly, is it drinkable?
Hearing this question, the experts all laughed. Zhang Qutong replied with a smile: "They are basically the same, but there may be some differences in isotopes. The moon has no atmosphere, which means it is directly exposed to the cosmic environment.
Affected by cosmic radiation, there may be some differences in water molecules.
Even on the earth, water is divided into many types, such as pure water, heavy water (deuterium water), tritium water, etc. The moon is exposed to cosmic radiation, so there may be some changes. However, it remains the same.
It’s still water. As long as it’s water, it’s not a big problem. It can still be drank directly after some treatment.”
