After separating from Wang Changwen, the two returned to the dormitory and chatted while looking for a suitable office space on the Internet.

"Hey, I said Nie Peng, what are you doing with the cultivation tank? Or outside the vacuum? You're going to catch Wild Ultraman, huh? ”

The other two roommates in the dormitory, one is a graduate school student, and the other is a civil servant, who is burying their heads in the library at this time, and they are angry and trying to be strong. At present, there are two people in the house, Chen Tuan and Nie Peng.

"I'm going to grab that thing and throw two of them to Japan, and we'll have more of them next year." Nie Peng nibbled on a cucumber.

"Huh? Why" Chen Tuan was confused

"Hey, how stupid is the bear... Because it attracts little monsters."

"Hahaha..." The two laughed

Ding Dong, Nie Peng's WeChat sound, opened it and saw that his father had transferred 5,000 yuan.

[Father, have you won the lottery? Are you sure you didn't press one more 0? 】

Nie Peng had already forgotten about the rocks brought back from the moon, although that thing was picked up from the moon, but for the moon, landing on the moon is climbing to the sky, and for him, landing on the moon is easier than going to the toilet, and he doesn't even need to step on his legs.

[The reward given by the bureau, the stone, is a lunar meteorite, report to the province tomorrow, you use the money first, and send me the address where you picked up the stone, to report]

Where can I find you an address, and locate you to the moon?

Nie Peng reluctantly picked an inaccessible place from the map and sent it to his father. This stone is not made from a tree that grows in the ground, it can be regarded as an unexpected event that cannot be traced, and it is said that it was picked up where it was picked up, and no one can prove the reason.

5,000 oceans is the first wealth brought to him by the moon, thinking about the stones on the moon, Nie Peng suddenly felt that it was so easy to get rich.

Of course, the same routine can't be used anymore, picking up meteorites all day and night, so what's the point? Next time, get a stone and see if anyone can collect it when it hangs on the meteorite net.

At dinner time, Chen Tuan had already left Nie Peng and kissed me with his girlfriend.

Nie Peng sent the parameters of the culture tank to Wang Changwen, planning to go to the moon for a field trip, but thinking of the uncomfortable lunar environment that was full of dust and made him itch when sticky, he still stopped the urge to set off immediately.

You have to find a way, or you will get silicosis sooner or later.

What Nie Peng didn't know was that the last astronaut on Apollo 17 to land on the moon had long complained about the "moon dust hay fever".

Even in 2011, NASA specifically developed a standard for exposure to lunar dust to limit the amount of airborne lunar dust in the environment to which astronauts will be exposed.

That's because during the Apollo mission, after the astronauts complete a spacewalk or out-of-cabin activity, a large amount of lunar dust adheres to the astronauts' out-of-cabin suits and boots and is carried into the capsule.

This dust is mainly unbonded particulate matter produced by repeated impacts of meteorite bodies during the formation of the moon, and these lunar dust attached to various surfaces of spacecraft can cause many failures, including mechanical structure jamming, sealing mechanism failure, optical system sensitivity, component wear, and thermal control system failure.

Moreover, it does not mean that quiet walking will not bring dust, because of the ultraviolet radiation and the action of the solar wind, the moon dust will be charged under the action of the surrounding plasma environment, and the electrostatic force acting on the dust is enough to overcome gravity and make the dust suspended in the air.

So for now, moon dust is still a big problem preventing people from landing on the moon.

A big problem for mankind, a small problem for Nie Peng, he went to the supermarket and bought a dozen dust masks and a high-pressure watering can.

A pressurized watering can for ten dollars.

Nie Peng's idea is very simple, everyone knows that when sweeping the floor, it is dusty, but sprinkling a little water will reduce it a lot.

This is due to the fact that the higher the moisture content of the dust, the smaller the amount of dust it produces. The principle of sprinkling water and dust removal is to spray water on the dust source to increase the viscosity and weight of dust particles.

So why didn't Apollo prepare two watering cans when he landed on the moon?

This is because even if you have a watering can that sprays water, the water vapor in the vacuum environment will not be able to stick to the dust, and there may even be a risk of short circuit caused by the vaporized water mist.

But does this have anything to do with Nie Peng? The water he sprayed out with the pressure watering can turned into small droplets, carrying the moon dust and flying far away, in this world, this is his unique reliance:

Everything comes according to the rules of the earth.

It's just that at present, this watering can is still a little insufficient, and Nie Peng, who is wearing a disposable dust suit taken from the laboratory and a three-layer dust mask, is like an agricultural technician spraying pesticides for crops at the moment.

Seeing that the mist sprayed in front of him drifted into the distance with most of the floating dust, and a small part of it stuck to his clothes, Nie Peng felt a little disappointed with the watering can in his hand.

Anyway, it's better than nothing. Waiting for the money, build a clean room, and use an ultrasonic atomizer to make a spray dust reduction system in and out, which should be much better.

While spraying water all over the sky, Nie Peng, who was looking for a suitable cultivation trough erection point, thought so.

The poor bread worm had already been torn into powder by the vacuum in the glass jar that he had placed behind the moon rock before, which also confirmed Nie Peng's guess.

As soon as he leaves the moon, then the special environment with him as the center of the sphere will immediately return to the rules of the moon, and vacuum, radiation, and violent temperature changes will ruthlessly tear apart the matter he brings, without exception.

Looking at the earth hanging in the air and not changing its position, the magnificent and transparent beauty can't be enough, but Nie Peng, who is a thief, always has the illusion of being peeped at, even if he knows that the most advanced telescope on the ground can only distinguish a 200-meter-sized lunar object, he still feels uneasy.

It's like a hen with a golden egg in her arms, and you have to watch out for it regardless of whether others know it or not.

Nie Peng walked on the surface of the moon, while looking for a suitable foothold, after many teleportations, he has gradually adapted to the gravity difference between the earth and the moon, found a bathroom with almost no one in the school experimental building, pasted a sign not to use in maintenance, and then locked the door of the bathroom, and the space inside was tossed with him.

Originally, he expected that the culture tank should be at least placed in a flat, stable environment.

The surrounding area should not be blocked by excessive terrain, but it should not be directly exposed to the view of the earth, so at present, it is ideal to choose a crater with a back to the earth as a shelter.

Just keep walking, keep spraying water, if the water is not enough, go back to the toilet to fill it, after going back and forth a few times, Nie Peng, who felt troublesome, simply found a big bucket, and carried it away after receiving the water, anyway, it is not heavy to carry on the moon.

Walking on the moon is not as comfortable as on the earth, due to the small gravitational pull of the moon, the weight of the human body is greatly reduced, which leads to a serious lack of friction generated by the upper of the shoe during walking, and it is very easy to slip.

The heavy moon dust is soft and has the illusion of walking in the snow. As the distance increased, Nie Peng felt more and more itchy skin on his legs, and his eyes were dry and unbearable.

Not far ahead, there was a rock exposed to the surface, Nie Peng gritted his teeth, went with difficulty, and looked back after arriving, this road of only two kilometers made him walk for forty minutes.

The stony ground is about 100 square meters, of which 80% of the ground is relatively flat, and it can be used if it is slightly flat, and the two tall rocks are just used to assume solar panels.

It was decided that it was here.

Finally getting rid of the dust all over the ground, Nie Peng picked up two stones, immediately returned to the earth, tore off the dustproof clothing covered with dirt, and threw them in the trash.

This kind of waste is often seen in the trash cans of the laboratory building, but he is not worried about being found out of anything abnormal, Nie Peng looked at the trousers and sneakers he was wearing, and he couldn't bear to look at it directly.

It's dirty, itchy, and choking.

Beeped Akita's feelings.

After a brief treatment, I decided to get a decent set of dust suits.

Back in the dormitory, Nie Peng took a shower and looked up information on solar panels on the Internet, a set of panels that can work for a long time in space is worth a lot, because to overcome various difficulties in the process of satellite launch, it is also necessary to meet the continued need for flexible adjustment in space, and a panel often integrates a number of top technologies.

But none of this is needed for Nie Peng, all he wants is a solar panel that meets the working temperature standard and can withstand vacuum, and even a tripod used to fix the panel can be exchanged at the thrift market.

The automatic sunshine system or something, just move it every day.

Nie Peng found more and more that his teleportation point on the moon was perfect, and the lunar sea area in the northern hemisphere, the long-term stable sunlight, and the large amount of solid ice that could exist were all ideal places for building a base. (The angle between the Moon's orbital plane and the equatorial plane around the Sun is only 1.5 degrees, which is not as large as the Earth's intersection angle (23 degrees), so there is little difference in insolation during the year at the Moon's poles, especially near the poles.)

If you are lucky enough to find the "Pirry" crater, which has many parts of the crater in sunlight all year round, and the ground temperature is stable around 20 degrees Celsius, you will not be able to ask for a beautiful scene.

After paying the order for solar panels, Nie Peng ordered some of the temperature control equipment in the cultivation tank in a certain treasure, and the 5,000 oceans that he only received in the morning went to 3,000 in a blink of an eye, which made him feel distressed.

After confirming the receipt information with the seller, Chen Tuan just came back. The two played a few sets of watchman butts, turned off the lights and went to bed.

"Shed, what do you call our company?" Soon after Chen Tuan lay down, he seemed to be asking Nie Peng, and he seemed to be muttering to himself.
