What?Other people are allergic to the moon?

In June 2019, on the 50th anniversary of the first lunar landing, Harrison Schmidt issued a warning at the Starmus Space Festival in Zurich. Many people may be allergic to the dust on the surface of the moon ...

Former American astronauts delivered a speech at a press conference in Zurich, Switzerland.

He said that these were not blind, because he really experienced it all.

In December 1972, before the Apollo plan was canceled, Harrison Schmidt was the only scientist who landed on the moon and participated in the last moon landing journey of the Apollo plan.

As a well -trained geologist, Schmidt spent a few hours to collect dust around the Litro Valley near the quiet sea, and collect rock samples from the moon surface.

In 1972, Schmidt, which was collecting lunar dust in the moon, was covered with dust on his shoes.

But when he returned to the landing warehouse, the accident happened.

The dust attached to the surface of the Aerospace suit follows Schmidt to the cabin. After taking off the heavy astronauts, Schmid's nasal cavity inhaled the dust from the moon, and there was an abandoned smell of gunpowder.

"When I first sucked into the moon dust, I immediately had an allergic reaction, my nose was swollen immediately, and my voice was not right. The back slowly relieved, and I didn't feel it when I was inhaled in the fourth time." Schmidt said at the Space Festival, "For some people, if they are exposed to the dust of the moon for a long time, we need to figure out whether they will be allergic."

Not only Schmidt's allergies to the dust of the moon, another flying surgeon also had severe allergies when Schmi specially unloaded Schmi to return to the ground, and even had to stop working at hand.

Speaking of which, maybe don't you think about it? Is there anything strange? Isn't the dust on the earth and the dust of the moon?

Yuechen particles are not spherical, but sharp.

No, it is really different, and the moon dust is much dangerous.

Amsterland was the first person to land on the moon. In the first few minutes of leaving the moon cabin, he reported to Houston's view of the moon dust: "The surface of the moon is fine powder. I can kick them with my feet. It is charcoal powder. I have a layer of powder with the soles of my soles and shoe. I only step into a few millimeters, perhaps 3 mm, but I can see the footprints on the fine sand particles. "It can be seen that the moon dust covers The surface of the moon cannot be avoided at all.

It is important that the moon dust is a residue of a tiny meteorite impact. Because there is no air or water erosion, each dust maintains a sharp corner and looks like a broken glass.

At the same time, the moon dust also has strong polishing, so that when the astronauts returned to the earth, the navigation bureau experts found that the three layers of the Schmidt boots were similar to that of the Kiffra fiber.

In addition, there is no atmosphere of the moon, and the dust is completely exposed to the radiation of the universe. This radiation brings a small amount of iron with a small amount of iron, making the dust particularly sticky. It may block or even damage the equipment.

After research by scientists, it was found that the moon dust was similar to silicon dust on the earth. You should have heard a occupational disease called silicon lung disease. Similar, scientists are also worried that the dust of the moon will cause similar threats to astronauts.

When a large amount of dust is inhaled into the human body, they are embedded in the tiny bubbles of the lungs and then swallowed by macrophages in the lungs. However, sand and dust cannot be decomposed by macrophages, causing macrophages to die, release the dust swallowed, and then vicious circulation, causing more cells to be damaged and causing obstacles to lung function. This is a disease that cannot be cured. It can only alleviate the symptoms through washing the lungs and extend life.

Because Schmidt did not inhale a lot of inhalation of the moon, it only contacted a little bit, so it was just allergies and did not cause great hindrance. If humans have colonized the moon in heaven and live and work on the moon for a long time, then the probability of pneumonia will greatly increase the probability of pneumonia for a long time. And the problem will only be more serious, because the moon dust is more sharp than the earth dust, which can penetrate the lungs deeper.

The threat of the moon dust is so great that scientists have been studying the way to fight the moon dust. Electronic beam cleaning is one of the methods. Special devices will shoot electronic beams to hit the dust, and the surface of the dust will gather negative charge. When the dust gathers enough charge, they may push each other to fly the moon dust on the Aerospace.

Vacuum room located in the University of California Boldish School

In the vacuum laboratory, the dust outside the electronic beam only takes a few minutes, but it is not perfect. On average, it can only clean up 75-85%of the dust on the surface.

In the future, if there is one day of this method of cleaning up the moon dust, maybe the astronauts will enter a cleaning room before entering the cabin in the future. Essence
