Super technology leader

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

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

It's just that they encountered the ultimate cheater, Tang Chao.

And Tang Chao's cheat is the entire Kan Star and the scientific research team on Kan Star.

Oh, and coincidentally, Kan Star is set as a race that extremely yearns for space, and its initial aerospace technology is slightly more advanced than similar technology on Earth.

However, after they "connected" to Earth, there was a tenfold time difference.

Counting from when Tang Chao obtained the Twin Star Gate, it has been almost three years now, while it has been almost thirty years on Kan Star.

Kan Star is not Earth. So far, Earth's aerospace activities have great political significance. Once the political aspect doesn't support it, it's not that aerospace development won't continue, but reduced funding will seriously affect the development of the aerospace industry.

Just like now, humans can't land on the moon. It's not that technology has regressed. The technological progress in recent years is obvious to all. It's really that political enthusiasm has waned. Humans haven't been on the moon for half a century.

On the contrary, for Kan Star, their journey to space is a necessity, a goal engraved in their genes, and they won't turn or stop for anything.

Aerospace funding will only increase year by year and will never decrease!

Based on the level of "Earth Aerospace Technology + 2", and then with the whole people participating in aerospace technology development for nearly thirty years, that level is like humanity's fantasy of colonizing Mars decades later when they landed on the moon decades ago.

Kan Star even has "cheats." Those black monoliths further promoted the development of Kan Star's technology, turning the Kan Star little green men into a true space race.

It's just that the time is still short, and the space of the "Kan Star Universe" is small, with only three star systems. Otherwise, they would be a cosmic race in a few more years.

As such a race, they are naturally experts in space survival. Even if they are strong enough on their own, they still have a lot of corresponding auxiliary technology.

They rarely eat food, but they have a pursuit of gourmet food, although their "gourmet food" is mostly related to green vegetables or green-colored food, but in terms of taste, it is still related to Earth.

After Tang Chao introduced some green vegetables to them, they happily accepted them.

Of course, they also accept meat and noodles, but the visual effect has to be changed.

For example, braised pork, when it arrives on Kan Star, it has to be called green braised pork.

Its method is similar to that of braised pork on Earth, but the caramelizing sugar step is omitted, and it is replaced with another sauce, resulting in a green batch.

Tang Chao has tasted green braised pork. You have to say, except for the color, the taste is the same as braised pork.

This further illustrates that the taste of the little green men is similar to that of Earth, at most with a slight difference in being sweeter or saltier.

In fact, this is similar to how heavy or light human tastes are.

Because of this, the technology they use in space food can also be used on Earth, and it is not harmful to people at all.

Cough, this is Tang Chao's personal test.

If you're not ruthless, you can't stand firm!

First, test it with body cells, and the theory is passed, then go for it!

What's more, he is already in a "superman" state. If he can't do it, then ordinary people on Earth definitely can't do it.

After he brought the technology over, because it was mature technology, the various laboratories tested it quickly, and a batch of results came out before the Starry Sky Inn went to space.

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

However, because the time was tight, they haven't used 100% Kan Star technology in space food yet. The space food seen in the live broadcast at most used 30% Kan Star technology, of which 20% was still because of the orbital shuttle.

Also, because the technology has not been 100% verified, the goods supplied to the Tiangong Space Station are just food that has removed the compression, freeze-drying, and dehydration steps, and are transported to the space station using the orbital shuttle.

You have to say, using the orbital shuttle to deliver goods, in addition to the small amount of goods delivered at one time, it is still cheaper when calculated, and it saves a series of steps such as compression, freeze-drying, and dehydration, which saves another sum.

Hey, it just so happens that the money saved is used to make some good-looking tableware, such as space bowls.

It's so refreshing to eat noodles holding a bowl!

Not only do the astronauts eat happily, but even the audience sees it happily.

Facts have proved that this live broadcast was very successful. The number of online viewers of the Pathfinder has broken the record again, even more than the last live broadcast when contacting aliens. It seems that people on Earth still care about the situation of their astronauts eating in the sky.

Many versions of the video of astronauts eating appeared on the Internet, and those videos were repeatedly watched by people, especially by the American Aerospace Administration.

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

"The confidentiality measures of Tianxia are too good. We didn't even know that their space meals have been upgraded. This degree of restoration is too high!"

"There's no way. We basically don't communicate in this area, and they haven't made it public. They directly used the Pathfinder Aerospace Company's package service, which is more secretive. If it weren't for this live broadcast, we wouldn't have known at all."

"I just want to know how our 'Adventure Star' is progressing? When can it be test-flown? We urgently need our own orbital shuttle!"

"Please pay attention to your wording, Tom. We should call the Adventure Star a spaceplane. This is our standardized name."

"Okay, you said it."

"Actually, we can completely buy the Pathfinder's Dart, aren't our relations pretty good now? We can completely cooperate, after all..."

"Okay, there's no need to say this. We just have a good relationship on the surface. Everyone knows the real relationship. Let's talk about the 'Adventure Star'."

In fact, the progress of Adventure Star is indeed good. Just like the space race back then, facing the pressure of a strong enemy, America's progress was very fast.

Now the prototype has been built, and because of the technological progress in recent years, its paper data is even better. It is currently undergoing ground tests. After these are completed, it can take off.

At that time, they will also have their own orbital shuttles... oh, no, spaceplanes.

Instead of the current two-stage small space shuttle to show off.

By that time, whether it is traveling between space and the ground, or when aliens plan to invade the Earth, they will have their own preparations.

With the strength of their America, they will definitely be able to cope with everything.

Well, this is what those politicians present thought.

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

From the video, the sense of ritual of that bowl of noodles is very strong, and these senses of ritual are exactly the taste of Earth.

Uh, although the technological content of that bowl of noodles in the video is indeed a bit high, and the production steps are also a bit complicated.

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

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

Weightlessness is a major enemy of mankind!

Species have evolved for billions of years, and finally evolved into humans, adapted to the gravity of the Earth. Suddenly, they are asked to use zero gravity, which is simply embarrassing.

During spaceflight, an astronaut's blood and other body fluids do not flow down the body as they usually do under gravity conditions.

Instead, the blood from the lower body flows back to the chest and head.

This can cause astronauts to experience facial swelling, head distension, varicose veins in the neck, headaches, nasal congestion, and an upward shift in the center of body mass.

And precisely, the human sense of smell and taste systems are here, which is why astronauts generally feel that eating has no taste.

In addition, those things that are pressed into cakes, freeze-dried, and extremely dehydrated, look quite messy, and they often don't feel that they are food.

Apart from those original fruits, chocolates, nuts and other things, those things have not changed much, but those things don't even need to be felt, they are not real food.

So many times, eating is really like chewing toothpaste.

Even worse than toothpaste, at least toothpaste is very refreshing to eat.

Once you don't eat well, and there is the influence of the space environment, then the astronauts will suffer.

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

Basically, it refers to the symptoms of cold sweats, nausea, vomiting, and dizziness caused by excessive movement stimulation of the vestibular balance receptors in the inner ear, which produces excessive bioelectricity and affects the nerve center when riding in a vehicle.

Then, stomach discomfort, and directly vomit.

Motion sickness on Earth can be treated with medication to alleviate symptoms, and even go to the hospital if it doesn't work.

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

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

Shortening billions of years of evolution time to a very, very, very short time, short to... the time of a few generations.

The experiment continues.

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

It takes them months to return to normal after returning to Earth.

In addition, spaceflight increases the risk of bacterial or viral infections, as well as reactivating latent viruses in astronauts.

When astronauts return to Earth, the immune system has changed significantly, and months of space life have 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 circadian rhythm, extreme temperatures and environmental noise, which can lead to hearing loss, lack of concentration, sleep disruption, and susceptibility to fatigue.

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

These are what astronauts know, or rather, the initial astronauts didn't know, because no one knew, so they needed to experiment day by day.

However, as space experiments have been carried out year after year, a large number of "destructive" consequences have appeared on astronauts. Later astronauts who entered space also knew, but they still entered space, willing to be experimenters for human civilization.

Even a pair of twin astronauts did a controlled experiment.

One brother completed a mission of nearly a year in space, while the other spent this time on Earth.

After the experiment, the brother in space had many changes in his body and genes, while his twin brother on Earth remained the same.

The changes in the space brother included thickening of the carotid artery and retina, weight loss, changes in intestinal microorganisms, decreased cognitive ability, DNA damage, changes in gene expression, and lengthening of chromosome telomeres.

One of the more surprising things was the lengthening of chromosome telomeres.

Telomeres are protective caps at the ends of chromosomes that shorten as humans age.

The lengthening of the space brother's telomeres shocked scientists in the American Aerospace Administration's human research program, even though they didn't know why his telomeres lengthened in space, but scientists will continue to study and find out the reason.

Those scientists want to study ways to lengthen telomeres in order to reverse aging or fight cancer.

The above is good news, and the bad news is that the change in telomeres in space is not permanent.

Because two days after the space brother returned to Earth, his elongated telomeres began to shrink, and the shrunk telomeres were even shorter than before he started the mission.

If his previous telomere length was 5, it became 7 after lengthening, and it directly became 3 after shortening!

Telomere shortening is related to aging and disease!

When elongated telomeres shorten or disappear, this can have some irreversible negative effects on the astronaut's cell health.

After careful examination, scientists found that 93% of the space brother's genes returned to normal after landing, but the remaining 7% had long-term changes.

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

The small portion of genes related to the immune system and DNA repair that failed to return to normal also indicates the potential for lasting damage to human genes from long-term living in space.

Under the current technological conditions, how to exempt humans from the harm of the universe is the research goal of scientists, but it is impossible to complete in a short time.

Since this is impossible to complete, then take another approach, such as making astronauts healthier in body and mind.

And eating is the primary issue.

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

If they are given something good to eat at this time, then they may be very happy.

If they are happy inside, then other things may be better.

And this point can allow humans to go further.
