This is how black technology should be used

Chapter 291 The Benefits of Simulating Gravity

In the rotating simulated gravity cabin, the astronauts basically don’t need a tether when using the treadmill. As long as the movements are standardized, they can run like on the earth, just a little bit floating.

But the effect is better after tethering.

You can lie down when you sleep, you can feel the softness of the mattress, you can cover yourself with a thin quilt, and you don’t need to find a sleeping bag to tie yourself up.

The toilet that simulates the gravity cabin is really great!

Although it also has certain space attributes, such as the toilet still has to actively pump air to let the excrement go down, but compared to the excretion in weightlessness, it is quite good.

There is also a washing process, such as taking a bath. In weightlessness, it is not called a bath, but just wipe it with a wet towel.

Now you can take a bath in the simulated gravity cabin. The water really flows from top to bottom, which is very refreshing.

You can sit firmly while eating, and you don't have to worry about floating while eating.

You don't have to worry about food residue flying around, even flying into your throat, making you cough.

It feels really good to drink soup from a bowl, and it feels like home.

The technology of separation and reuse of oily fumes is perfect, allowing them to cook and eat in the simulated gravity cabin of the space station!
Whoever eats the space stir-fry just out of the pan will know!

There are so many things that can be done with the gravity of 0.4g, which is much stronger than the gravity of the moon. Previously, the astronauts on the space station envied their colleagues at the lunar outpost who could sit and eat peacefully, but they did not expect that they can do it now.

And better.

These explicit benefits are not the most important. The implicit benefits are the core motivation for the development of the simulated gravity cabin.

As we all know, space travel can explore the unknown, experience adventure and excitement, and satisfy human's thirst for knowledge of novel things.

But this is limited to short-duration space travel.

Practice has proved that long-term space flight in a weightless and vacuum environment will cause serious damage to the astronauts' bodies, such as muscle atrophy or cancer.

At present, the longest time an astronaut stays in space is more than 400 days, and the time spent in space will become longer and longer in future space exploration, so it is necessary to understand weightlessness, high vacuum, large temperature fluctuations and high-energy radiation How the space environment affects human health and how to overcome them one by one.

Weightlessness will cause changes in cardiovascular function, as I said before, it will make the face bigger and the neck thicker.

This is during spaceflight when an astronaut's blood and other bodily fluids don't flow down their lower body as they customarily do under gravity.

On the contrary, the blood in the lower body will flow back to the chest cavity and head, which can cause facial edema, head swelling, varicose veins in the neck, headache, nasopharyngeal blockage, and upward shift of the body center of mass.

In the first few days, astronauts also suffer from motion sickness, also known as space motion sickness, which is similar to any other form of travel sickness and refers to excessive motion stimulation of the vestibular balance receptors in the human inner ear while traveling in transportation.

At this time, the vestibular organ will generate excessive bioelectricity, which will affect the nerve center, and finally symptoms such as cold sweat, nausea, vomiting, and dizziness will appear, accompanied by symptoms such as stomach discomfort and vomiting.

If you were wearing a helmet, you could even spit directly into the helmet, that would be an exciting scene.

On Earth, people who suffer from motion sickness can take medicine to relieve symptoms, but on the space station, astronauts cannot use medicine even if it causes more serious space motion sickness.

Because the space environment will cause various conditions, even if it is used, it must be a special drug developed for space conditions.

After three months in space, some astronauts experience muscle atrophy and lose as much as 30 percent of their muscle mass, which can take months for them to return to normal after returning to Earth.

In addition, spaceflight can increase the risk of bacterial or viral infections, and even reactivate some dormant viruses in astronauts.

By the time astronauts return to Earth, their immune systems have undergone significant changes, and months of living in space have caused them to lose 8% to 12% of their bone density, which can take up to three years to recover.

Additionally, other health factors of space travel include psychological stress, disrupted circadian clocks, extreme temperatures and environmental noise, which can lead to hearing loss, poor concentration, disrupted sleep and susceptibility to fatigue.

Most of these problems are caused by the weightless environment. As long as the astronauts feel gravity again, these problems will be more or less alleviated.

For, in addition to weightlessness, there is equally dangerous high-energy radiation.

When astronauts leave the ground, they also leave the thickest atmosphere and magnetic field protection. The atmospheric molecules in space orbit are already very thin.

Without the protection of the atmosphere and a part of the magnetic field, high-energy radiation will have a dangerous effect on the human body. After all, the thin protective layer of the space station is definitely not as good as the atmosphere that is hundreds of kilometers thick.

High-energy radiation in the Earth's orbit comes from cosmic rays and solar flares in the Milky Way. Long-term exposure to high-energy radiation will kill cells and damage DNA, which may lead to an increased risk of cancer and cataracts.

But everything has two sides, and there are both disadvantages and advantages in a zero-gravity state.

For example, some situations that are unfavorable to normal people, in turn, can actually relieve back pain and improve blood circulation in some patients.

Moreover, Practical Science and Technology Aerospace Corporation develops a new technology almost every day. The bulkhead protection layer that simulates the gravity orbital module is the new material of Practical Science and Technology Aerospace Corporation.

In addition, the new drug from the life science research department of Practical Science and Technology Aerospace Company has been used by returning astronauts. It can not only eliminate space radiation damage, but also strengthen the human body, which is very powerful.

However, this matter is currently top secret, and very, very few people know about it.

If the effect is satisfactory, maybe humans will soon be able to add a new [space survival] attribute and enter the interstellar era.

Of course, those are too far away, and the performance of simulated gravity has already made many people ecstatic.

It's just that unlike the shocked, excited and watching netizens, some people are sour.

On the International Space Station, the resident astronauts grasped the limiter with their hands and hooked their feet, struggling to maintain their balance in weightlessness, and watched a new video released by the Starry Space Agency in front of a laptop.

As astronauts, they have much more to consider than ordinary people.

"This technology is too powerful!"

"Yeah, I wonder when the International Space Station will be available?"

"It's probably impossible. No one knows the aging speed and extent of the International Space Station better than us. It really won't last for a few years."

"Alas, there's nothing we can do about it. Today's technology is developing too fast..."
