This is how black technology should be used

Chapter 195 The Heroic Astronaut
"Ahem, I don't think this plan will help me, and I'm in good health and don't need any help."

"In fact, the Federation has always been a peace-loving country, but we have been fighting for world peace, so it is very good to use this technology on soldiers."

"But for the sake of peace, let's try not to mention the word 'soldier' ​​as much as possible, let's look up at the starry sky, there is no other meaning... I just think this technology is very suitable for astronauts and space exploration."

Dengzi coughed twice and said with a straight face.

"So when announcing this plan to the public, talk more about the situation of the astronauts..."

As he spoke, he winked at the scientific advisor, who immediately received the message and said, "Yes, we should pay more attention to the starry sky than the war on Earth, because there is the future of human beings there."

"It's just that human beings have been living on the earth and have adapted to the earth's environment long ago. Therefore, the space environment has a great negative impact on astronauts. They are the heroes of mankind..."

There were aerospace experts at the meeting, and they all knew that what the commander-in-chief and the scientific adviser said earlier was nonsense, but what was said later was true.

Astronauts are indeed heroes.

After entering space, every astronaut will suffer from space sickness.

Space sickness refers to astronauts working in a weightless environment and facing a series of health threats including motion sickness, bacterial infection, space blindness, psychological problems and toxic dust.

In the zero-gravity space environment, the astronauts' bodies undergo various changes like adolescents.

And most of these changes are bad.

Normally, astronauts need time to adapt to the state of weightlessness when they first enter space, such as dizziness, dizziness, pale face, cold sweat, abdominal discomfort, nausea, vomiting, and some also have increased saliva, belching, lethargy, headache and other symptoms. Neurological symptoms.

During this time, many astronauts experience motion sickness, hallucinations and disorientation.

This is space adaptation syndrome.

The proportion of astronauts suffering from space adaptation syndrome is about half, and the condition varies from person to person. Although the symptoms of adaptation syndrome usually disappear after a few days, it is dangerous.

Astronauts in spacesuits need to take anti-emetics to combat motion sickness, as free-floating vomit in spacesuits can cause horrific suffocation and endanger the lives of astronauts.

After adapting to the zero-gravity environment, it is not the end, but a beginning. At this time, some strange changes will occur in the astronaut's body.

The weightless environment causes bodily fluids to flow around, mainly to the torso and head, causing facial swelling and inflammation, such as nasal congestion, in astronauts.

During their long-term stay in space, astronauts are always in a curled up position, just like a fetus, and it takes conscious effort to stand upright.

The weightlessness causes the soles of the astronauts' feet to molt like some reptiles do, exposing the pink skin underneath.

And all kinds of hazards not only come from space, but also from the ground.

Although astronauts and cargo have to undergo various cleaning procedures before taking off, some things are still inevitably brought up, such as bacteria and fungi.

According to the survey, there are 234 kinds of bacteria and fungi living on the "Mir" space station, which does not include the bacteria on the astronauts' bodies.

Although most of these microorganisms are beneficial to astronauts, there are also "pests" among them.

Harmful bacteria in space can cause conjunctivitis, acute respiratory disease and dental infections.

And in space, the antibiotics prepared for astronauts require higher concentrations and are not as effective as when used on Earth.

In zero gravity, the most feared germ is Salmonella typhimurium, because it can cause... acute gastroenteritis!

Due to the relaxation of abdominal muscles caused by weightlessness, many astronauts also fart.

These symptoms are combined together, and in the airtight, weightless environment of the space station, the lethality is quite strong.

The most well-known effect of weightlessness is the degeneration of bones and muscles.

During a one-month stay in space, the average astronaut loses between 1% and 2% of their bone mass.

Astronauts suffer more muscle loss than bone loss, with an average muscle loss of up to 5% for a week of stay!

As the calcium in the bones enters the blood, astronauts are at an increased risk of developing kidney stones, and if they do, they will be in great pain.

In addition, calcium-deficient bones also become very fragile and prone to fractures, which is why some astronauts need to sit in seats after landing.

If regular exercise can slow down the decline of bones and muscles, then the gradual decline in vision of astronauts is much more serious, and the more time spent in space, the more severe the symptoms of vision loss, and may even be permanently blind.

When performing short-term missions, about 30% of astronauts have blurred vision, and the proportion of astronauts performing long-term missions has doubled!
Scientists are not yet sure what exactly causes space blindness, but some believe it may be related to increased hydraulic pressure in the head, which compresses the optic nerve in the eyeball and causes blindness.

But the most dangerous, and totally unavoidable, are solar storms and radiation.

These two things are among the biggest challenges of long-duration spaceflight.

Without the protection of Earth's magnetic field, astronauts are exposed to far more radiation than normal, and their cumulative radiation exposure in low Earth orbit exceeds that of workers near nuclear reactors, with a high risk of cancer.

Solar flares and other solar eruptions can produce dangerous waves of X-rays and heavy charged particles that can penetrate astronauts' bodies, damaging DNA and increasing the risk of cancer, as well as destroying equipment.

This is still in the earth's orbit, with some protection from the earth's magnetic field. If it is on the moon far away from the protection of the earth's magnetic field, the amount of radiation will be even greater.

And after landing on the moon, astronauts will not only face the problem of excessive radiation.

At the beginning, the astronauts of the Freedom Federation went out of the cabin and scrambled on the surface of the moon. When they returned to the cabin, they also brought in the fine moon dust on the spacesuit. As a result, the fine moon dust would irritate and wear the astronauts eyes and skin.

Leaving aside the toxicity of these moon dust, since there is no weathering phenomenon on the moon, the sharp edges and corners of inexplicable dust particles are very dangerous.

If it enters the lungs, the consequences are more serious.

Many scientists believe that Martian dust is more dangerous than lunar dust. The iron oxide in it will corrode organic compounds such as plastics and rubber, and it will also burn people's skin.

Storms on Mars whip up dust and send it through the tiniest of crevices.

So astronauts on future missions to the Moon and Mars will need to take serious precautions against misplacement and toxic dust intrusion.

Practical technology is crossing the river by touching the Freedom Federation. There is a separate airlock at the entrance of the outpost test cabin. During the process of boosting and depressurizing, there will be strong wind removal and electromagnetic adsorption effects, and it will try to eliminate the airlock attached to the spacesuit. Hazardous dust.

In addition to these physical hazards, psychological hazards are equally deadly.

Living and working in space is an extremely stressful experience that tests the psychological endurance of astronauts.

In space, they are isolated, living in a small space, without family and friends. In this case, a long space flight can lead to a series of psychological problems, including depression or volatility, mental vulnerability, anxiety and fear. .
