The rise of nanometers

Cheng Cunwu was not too surprised after reading the drilling report. After all, the space agency had previously explored some geological conditions of the moon through geological remote sensing satellites.

He even knew that there was a large amount of solid ice water at the bottom of the eternal night-type craters in the polar regions of the moon.

According to the current preliminary detection data, the water resources reserves in the polar regions of the moon are approximately 8.4 billion cubic meters.

This is just that the surface strata contain water resources. In a series of lunar seismic wave data, the Lunar Seismological Research Institute affiliated with the space agency found that there is a huge amount of liquid feedback in the deep crust of the moon.

For example, the purpose of the drilling experiments being conducted at Guanghan Palace Base at this time is to verify some theories.

If the Lunar Geology Institute's research is correct, the drilling machine will find liquid water about 120 to 140 meters underground.

He looked at the time. According to the current progress, the drilling rig could drill down about 0.3 to 0.5 meters per hour on average.

The reason why it is so slow.

On the one hand, due to heat dissipation issues, the base does not have a large amount of water, so heat cannot be dissipated with water. In addition, the lunar surface is almost vacuum, which is not conducive to heat dissipation. The drill must stop at intervals to conduct heat to the surrounding rock formations.

On the other hand, it is to protect the rock formation samples and ensure that the rock formation samples will not deviate too much.

While Cheng Cunwu was reading the drilling report, Yu Shengtian went to the communication cabin in the living area to package and send the experimental data of the past few days back to Blue Star.

The confidential communications at the Guanghan Palace Base use a laser communications system, which is currently the most confidential communications system.

The only trouble is that several laser communication relay satellites need to be deployed.

In the living area, Cheng Cunwu came to the wash cabin dedicated to bathing. Although the gravity of the moon is only one-sixth of the Blue Star, it is still gravity after all, which is much better than the space station floating everywhere.

In the bathroom, Cheng Cunwu took off his clothes and turned on the shower head, and the negative pressure water absorption system under his feet was activated at the same time, which can accelerate the water falling to the floor, simulating the bathing state on the Blue Star floor.

In addition, he also wears a semi-covered waterproof respirator, which is like a mask and covers the mouth and nose to prevent water droplets from entering the respiratory tract.

In a low-gravity environment, bathing is also troublesome and dangerous. Without a respirator, accidentally inhaling a large amount of water droplets into the lungs can cause suffocation.

Hot circulating water sprayed down from the shower head. Even though there was negative pressure to absorb water from the floor, the water droplets still fell slowly, as if in slow motion.

Cheng Cunwu also moved quickly without any sloppiness. He finished the bath in about ten minutes. After turning off the shower head, the negative pressure water absorption system was still running.

Grab a special hair dryer and dry your body and hair.

When he organized everything and walked out of the wash cabin, Yu Shengtian, who had gone to send the experimental data, had returned and was eating.

In the kitchen cabin, there was Shi Keji, who was in charge of the geological experiment cabin, and he was also eating.

Cheng Cunwu opened the food storage cabinet, picked out a portion of Kung Pao Chicken, a portion of Spicy Beef, a portion of Fried Lettuce, plus steamed buns, and threw them into the electric oven to heat, and then he picked up a Gannan navel orange.

Turning around, he inserted a special drink bottle into the cold drink machine, clicked the [Sour Plum Juice] button, and soon a 200 ml bottle of sour plum juice was poured into the drink bottle.

Take a sip of sour plum juice to stimulate your taste nerves. In a low-gravity environment, human taste will become insensitive, so you need some strong-flavored food.

Ding dong!

After the heating was completed, he put on insulated gloves and took out the food. All the food was made into small packages, basically one-pack-sized portions.

For example, small steamed buns are served one bite at a time, 10 in a portion, somewhat similar to aluminum-sealed steamed buns.

Cheng Cunwu tore open the package of a small steamed bun, put it directly into his mouth, and then bit into half a piece of spicy beef.

The three of them did not speak, but concentrated on eating. They were mainly worried about the danger. In a low-gravity environment, people might choke to death when eating and talking.

If food is sucked into the respiratory tract, rescue must be carried out. Aerospace Science and Technology has specially designed a set of respiratory foreign body cleaning equipment just in case.

Therefore, astronauts must be careful when eating, and talking while eating is absolutely not allowed.

After dinner, everyone began to perform their duties again, resting when they should, and changing shifts when they should.

Cheng Cunwu and Yu Shengtian came to the communication cabin to communicate with the ground. Due to communication delays, they could only communicate through text and pictures for the time being, and could not directly use video calls.

The two went through the ground command center to discuss some situations of electric field synthesis with Xie Qing's ground team.

The discussion lasted more than an hour.

Cheng Cunwu stopped, looked at the dense data, and rubbed his temples with a headache: "The gravity environment of the moon has a very serious impact on the formation of silicon nano-coating. Even the previous liquid electroplating method is difficult to form a perfect layer. Plating.”

Suddenly Yu Shengtian said: "Cunwu, there is actually a way, such as using a centrifugal system to simulate the gravity of Blue Star."

"Centrifugal system?" Cheng Cunwu frowned. He knew what a centrifugal system was. This is currently the most likely artificial gravity technology that humans can realize.

Just using centrifugal force to replace gravity will make the system very large and require a lot of engineering work.

If you want to implement a centrifuge system on the moon, you will need a very large centrifuge. Whether it is a super large motor, energy, or centrifuge body materials, these will require a lot of resources.

Although the transportation capacity of various local space cities, regardless of the cost, they can achieve a transportation volume of tens of thousands of tons a year.

But the transportation volume of tens of thousands of tons is just a drop in the bucket for the centrifugal pseudo-gravity system. He roughly estimated that the entire centrifugal pseudo-gravity system would require at least hundreds of millions of tons of materials to build.

For the current urgent space race, this kind of project consumes too many resources. Even if Greater China has controllable nuclear fusion technology and efficient element refining technology, it cannot withstand this terrible consumption.

Cheng Cunwu shook his head: "The centrifugal plan consumes too many resources..."

But Yu Shengtian interrupted him: "No, I don't want to build a large centrifugal space city. We only need a space capsule, even the size of a can."

"..." Cheng Cunwu thought for a while, but was still not optimistic about this plan: "This is just a temporary solution, not the root cause. We still need to find a technology that can synthesize electric fields in the lunar environment. The centrifugal solution cannot be mass-produced."

Yu Shengtian was speechless. His plan could only be used in the laboratory. The laboratory plan was of little use to the Guanghan Palace base at this time.

The solution they need at this time is a technology that can be mass-produced on the moon, similar to the production technology of foamed silicon steel.

Three locally customized foam silicon steel composite cabins will arrive at the Guanghan Palace base in two weeks.

By then, these three synthetic cabins will be able to produce about 400 to 600 cubic meters of foamed silicon steel materials every day. The density of foamed silicon steel is not high, weighing only about 1.2 tons per cubic meter, and its density is only slightly higher than water.

The skeleton material of the base can be mass-produced on a large scale, but the sealing material of the shell has been unable to adhere to silicon nanoparticles, which has become a shortcoming of the Guanghan Palace base.
