Super technology leader

The upgrading of space food has always been accompanied by the development of science and technology, as well as the advancement of human cognition of the relationship between the human body and the universe.

This takes time and requires step-by-step verification, so the fourth-generation space food is already very good.

It's just that they ran into Tang Chao.

However, Tang Chao's affair was forced by the entire Kanxing and Kanxing scientific research team.

Hey, it just so happens that Kanxing's setting is a race that is extremely aspiring to space, and the initial aerospace technology is slightly more advanced than similar technologies on the earth.

But after there was "connected" to the earth, there was a tenfold time difference.

It has been almost three years since Tang Chao got the Double Star Gate, while it has been almost 30 years since Kan Xing.

Kanxing is not the Earth. So far, the Earth’s space activities are of great political significance. Once political support is not given, it will not be said that space development will not continue, but the reduction of funds will indeed seriously affect the development of space industry.

Just like now, mankind can't land on the moon. It does not mean that technology has regressed. The technological progress in these years is obvious to all. It is indeed that political enthusiasm has faded. Mankind has never been on the moon again in half a century.

On Kan Xing's side, it was the opposite. They were just needed to go into space, they were targets carved in their genes, and they wouldn't turn for anything.

Space funding will only increase year by year, never decrease!

Based on the level of "Earth and Space Science and Technology + 2", and then the whole people have participated in the development of space science and technology for nearly 30 years. That level is the same as when humans dreamed of colonizing Mars decades later when they landed on the moon decades ago.

Even Kan Xing has "plug-ins". Those black obelisks further promoted the development of Kan Xing's technology, turning the Kan Xing little green people into a space race.

That is to say, the time is still short, and the space of the "Kanxing Universe" is also small, with only three star systems, otherwise they will be a cosmic race in a few years.

As such a race, space survival is naturally a master, even if they themselves are strong enough, but there are still many corresponding assistive technologies.

They seldom eat food, but have a pursuit of food. Although most of their "food" is connected with green vegetables or green food, in terms of taste, it is connected with the earth.

After Tang Chao introduced some green vegetables over there, they also accepted it with pleasure.

Of course, meat and noodles are also accepted, but the visual effects are slower.

For example, braised pork in brown sauce, in Kanxing, it has to be called green braised pork.

Its method is similar to that of teriyaki braised pork, except that it saves the sugar color. Instead, it replaced it with another sauce and produced a green batch.

Tang Chao has tasted green braised pork. Don’t mention it. Except for the color, the other flavors are the same as braised pork. This further shows that the taste of the little green man is similar to the taste of the earth, at most it is sweet or partial. The difference is saltier.

In fact, this is similar to the taste between humans.

Because of this, the technology that the other party uses for space food can also be used on the earth side, and there is no harm in using it on humans.

Well, this was tested by Tang Chao himself.

People are not ruthless, can't stand steady!

I've tried it with body cells first, and the theory has been passed, so let's go ahead!

What's more, he is now in a "superman" state. If he can't do it, then ordinary people on earth will definitely not do either.

After he brought the technology, because it was a mature technology, the various laboratories tested it quickly, and a batch of results were released before the Starry Sky Inn went to the sky.

It can indeed make space food more delicious, or restore its earth flavor.

It's just that because time is tight, they haven't used 100% Kanxing technology in space food. The space food seen in the live broadcast uses at most 30% Kanxing technology, and more than 20% of them are due to orbital shuttles.

Because the technology has not yet been 100% verified, the goods supplied to the Tiangong space station are only to remove compressed, freeze-dried, and dehydrated food and transport them to the space station using an orbital shuttle.

Not to mention, the use of orbital shuttles to deliver less goods in a single delivery, but it is still cheaper, and it saves a series of steps of compression, freeze-drying, and dehydration.

Hey, the money just saved to make some good-looking tableware, such as space bowls.

Holding a bowl to eat noodles, refreshing!

Not only did the astronauts eat well, but even the audience enjoyed it.

Facts have proved that this live broadcast was very successful. The number of live broadcasts of Navigator broke a record, and it was more than the live broadcast of the last contact with aliens. It seems that people on earth still care about their astronauts eating in the sky. Case.

There have been many versions of the video of the astronaut eating on the Internet, and those videos have been watched repeatedly, especially by the Meriken Space Agency.

Later, the dining video of the Tiangong Space Station was also uploaded, and it was watched and analyzed repeatedly.

"Tianxia's secrecy measures are so good, we didn't even know that their space meal has been updated, and the degree of restoration is too high!"

"No way, we basically don't communicate in this aspect, and they didn't publicize it. They directly used the package service of Navigator Aerospace Company, which is more confidential. If it were not for this live broadcast, we would not know."

"I just want to know how our'Adventure Star' is progressing? When will the test flight be available? We desperately need our own orbital shuttle!"

"Please pay attention to your own words, Tom, we should call Adventure Star Skyplane. This is our standardized name."

"Actually, we can buy the Navigator's Darts. Isn't the relationship between our two parties very good? We can have some cooperation, after all..."

"Okay, I don't need to talk about it. We are just superficial. In fact, everyone knows the real relationship. Let's talk about the "Adventure Star"."

In fact, Adventure Star is really good, just like the original space race, in the face of the pressure of powerful enemies, Meriken's progress is very faster.

Now the prototype has been built, and because of the advancement in science and technology over the years, its paper data is better. It is currently undergoing ground tests. Once these are completed, it can take off.

At that time, they will also have their own tracks to wear...oh no, it's an aeroplane.

Instead of the current secondary small space shuttle.

At that time, whether it is traveling between the sky and the ground, or waiting for aliens to invade the earth, they will have their own preparations.

With their Meriken's strength, they can definitely handle everything by then.

Well, this is what the politicians in the room think.

The scientists present are thinking more realistically. They are still analyzing the "new generation" of space food.

From the video, the ritual sense of the bowl of noodles is very full, and these ritual senses are just the taste of the earth.

Uh, although the technology content of the bowl of noodles in the video is indeed a bit higher, the production steps are also a bit more complicated.

However, from the perspective of human emotions, that bowl is not even a real bowl, but a paper bowl, but the meaning it represents is truly extraordinary.

People always say that the future of mankind is the sea of ​​stars, but the human body is not suitable for the sea of ​​stars.

Weightlessness is a great enemy of mankind!

The species has evolved for hundreds of millions of years, and finally evolved into a human being, adapted to the gravity of the earth, and suddenly asked him to use weightlessness, which is simply embarrassing.

During space flight, the blood and other body fluids of astronauts do not flow down the body as usual under gravity conditions.

On the contrary, blood from the lower body returns to the chest cavity and head.

This can cause astronaut facial swelling, head swelling, neck varicose veins, headaches, blockage of the nasopharynx, and shifting the center of body mass.

And precisely, the human sense of smell and taste system is here, which is why astronauts generally feel no taste when eating.

Plus those pressed into cakes, freeze-dried, and extremely dehydrated, it looks quite messy, and they don't feel that it is food many times.

Except for the original fruits, chocolates, nuts and other things, those things have not changed much, but those things don't even feel like they are not serious food.

So many times eating is really like chewing toothpaste.

Even toothpaste is inferior, at least the toothpaste is sour and refreshing.

Once the food is not good enough and the space environment is affected, the astronauts will suffer.

In the first few days, astronauts will also get motion sickness, also known as space motion sickness, which is similar to any other form of travel sickness.

Basically, it refers to symptoms such as cold sweat, nausea, vomiting, dizziness and other symptoms that occur when the vestibular balance receptors in the human body are stimulated by excessive exercise during transportation, and the vestibular organs produce excessive bioelectricity, which affects the nerve center.

Then, the stomach is upset, and I vomit directly.

If motion sickness occurs on the earth, drugs can be taken to relieve symptoms, or even go to the hospital if it doesn’t work.

But in space, in the space station, even if it causes more serious space motion sickness, astronauts cannot use drugs.

Sometimes I have to say that astronauts are actually part of space experiments, and even they just need to pay pains to bring considerable experimental data to the entire human population.

Shorten the evolution time of hundreds of millions of years to a very short, very short, very short, as short as... a few generations.

The experiment continues.

After three months in space, some astronauts may experience muscle atrophy and even lose up to 30% of their muscle mass.

It will take several months for them to return to normal after returning to Earth.

In addition, space flight will increase the risk of bacterial or viral infection and reactivate the latent virus in the astronauts.

When the astronauts returned to Earth, the immune system had changed a lot, and months of life in space caused them to lose 8%-12% of their bone density.

It may take up to three years to recover.

In addition, other health factors of space travel include psychological stress, disruption of the day and night biological clock, extreme temperatures and environmental noise, which may cause hearing loss, inattention, sleep interruption and susceptibility to fatigue.

Astronauts are also exposed to high-energy radiation, radiating cosmic rays and solar flares from the Milky Way.Long-term exposure to high-energy radiation can kill cells and damage DNA, which may increase the risk of cancer and cataracts.

These are all astronauts know, or the original astronauts did not know, because everyone does not know, so it takes day by day experiments.

However, as space experiments continued year after year, a large number of "destructive" consequences appeared on astronauts. Astronauts who later entered space knew about it, but they will still enter space and are willing to experiment with human civilization. personnel.

There are even a bunch of twin astronauts who have done a controlled experiment.

One of the two brothers completed nearly a year's mission in space, and the other spent this time on Earth.

After the experiment is over, the brother in space has undergone many changes in his body and genes, while his twin brother on Earth is doing business as usual.

The changes in Space Brothers include thickening of the carotid artery and retina, weight loss, changes in intestinal microbes, cognitive decline, DNA damage, changes in gene expression, and chromosomal telomeres.

One of the more surprising is the lengthening of chromosomal telomeres.

Telomeres are the protective caps at the ends of chromosomes. As humans age, telomeres become shorter.

The telomeres of the Space Brothers became longer and shocked the scientists of the Human Research Project of Meriken Space Agency. Even though they did not know why his telomeres became longer in space, scientists will continue to study to find out why.

Those scientists want to study ways to extend telomere length in order to reverse aging or overcome cancer.

The above is good news, but the bad news is that telomere changes in space are not permanent.

Because two days after the Space Brother returned to Earth, his elongated telomeres began to shrink, and the shrinking telomeres were even shorter than before they started to complete this task.

If his telomere length was 5 before, it becomes 7 after being extended, and it becomes 3 directly after shortening!

Telomere shortening is related to aging and disease!

When the elongated telomeres shorten or disappear, this will have some irreversible negative effects on the cell health of the astronauts.

After careful inspection, the scientists found that after the Space Brothers landed, 93% of the genes returned to normal, but the remaining 7% had undergone long-term changes.

His immune system, DNA repair, and genes related to hypercapnia have all undergone irreversible changes.

The failure of a small number of genes related to the immune system and DNA repair to return to normal also indicates that long-term living in space has the potential to continue to damage human genes.

Under the current technical conditions, how to avoid the harm of the universe to mankind is the research goal of scientists, but it is impossible to complete it in a short time.

This can’t be done, so take another approach, such as making the astronauts physically and mentally healthy.

And eating is the primary issue.

Many astronauts are picky eaters in space, but that is not something they can control, it is a passive "curse."

If you let them eat something good at this time, then they might be very happy.

I am happy inside, and the others may be better.

And this can make humans go further.
