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

This takes time and needs to be verified step by step, so by now the fourth generation of space food is already very good.

It's just that they ran into Tang Chao.

And the hanging of Tang Chao is the entire Kanxing and the scientific research team on Kanxing.

Hey, it just so happens that the setting of Kan Xing is a race that is extremely yearning for space, and the initial space technology is slightly more advanced than similar technology on the earth.

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

It has been almost three years since Tang Chao got the Twin Star Gate, and it has been almost thirty years on Kan Xing's side.

So far, the political significance of the earth's space activities is extremely great, once the political side does not support it, it will not say that the development of space cannot continue, but the reduction of funds will indeed seriously affect the development of the space industry.

Just like now, human beings can't go to the moon, not that science and technology have regressed, the scientific and technological progress in recent years is obvious to all, it is true that political enthusiasm has faded, and mankind has not been on the moon for half a century.

On the other hand, on the other hand, they are just going to space, they are the goal engraved in their genes, and they will not turn around for anything.

Aerospace spending will only increase year by year, never decrease!

Based on the level of "Earth Aerospace Science and Technology +2", and then the whole people have participated in the development of aerospace science and technology for nearly 30 years, that level is the same as the current colonization of Mars decades later when humans landed on the moon.

Even Kanxing has "plug-ins", and those black monuments have further promoted the development of Kanxing technology, making the Kanxing little green men truly become a space race.

That is, 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 a lot of corresponding auxiliary technologies.

They rarely eat food, but they have a desire for food, and although most of their "food" is related to green vegetables or green foods, in terms of taste, it is still related to the earth.

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

Of course, meat and noodle products are also accepted, but the visual effect has to be slowed down.

For example, braised pork, when it comes to Kanxing, it has to be called green braised pork.

Its method is similar to that of braised pork on the earth, except that the color of the fried sugar is saved, but it is replaced with another sauce to make a green batch.

Tang Chao has tasted green braised pork, don't you say, in addition to the color, the other flavors are the same as the braised pork, which further shows that the taste of the little green man is similar to the taste of the earth, at most it is a difference between sweet or salty.

In fact, it's similar to whether human tastes are heavy or not.

Because of this, the technology that the other party uses for space food can also be used on the earth side, and it is not harmful to use it on people.

cough, this is Tang Chao's personal test.

People are not ruthless, and they can't stand steadily!

I've tried it with body cells first, and the theory has passed, so it's on the bar!

What's more, he is now in a "superhuman" state, and if he can't do it, then the average person on Earth definitely can't do it either.

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

It can really make space food more delicious, or restore its earthly taste.

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

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

Don't say that the use of rail shuttle delivery is not only less than a single delivery of goods, but it is still cheap, and it saves a series of steps of compression, freeze-drying, and dehydration, and saves another sum.

Hey, just save this money to make some nice cutlery, like a space bowl or something.

Hold a bowl and eat noodles, cool fly!

Not only the astronauts ate well, but even the audience watched it well.

It turned out that the live broadcast was very successful, and the number of live broadcasts of the Navigator broke records again, more than the last time they contacted aliens, and it seems that people on Earth still care about their astronauts eating in the sky.

There are many versions of the video of the astronauts eating on the Internet, and those videos have been watched over and over again, especially by the Merriken space agency.

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

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

"There's no way, we basically don't communicate in this regard, and they don't publicize it, they directly use the package service of the Navigator Space Company, which is more secretive, if it weren't for this live broadcast, we wouldn't know at all."

"I just want to know how our 'Adventure Star' is progressing? When will I be able to test fly? We are in dire need of our own orbital shuttle! ”

"Watch your wording, Tom, we should call Adventure Star an aerospace plane, that's what we call it."

"Actually, we can buy the Navigator's Dart, isn't the relationship between us very good now, and we can have some cooperation, after all, ......"

"Okay, needless to say, we're just pretty good on the surface, in fact, the real relationship, everyone knows, let's talk about the 'adventure star'."

In fact, the adventure star is really good, just like the original space race, in the face of the pressure of strong enemies, Merrican's progress is very faster.

Now that the prototype has been built, and because of the technological advances over the years, it has better data on paper, and it is currently undergoing ground trials, and when this is done, it will be ready to take off.

At that time, they will also have their own track to wear...... Oh no, it's an aerospace plane.

And not the current small space shuttle of the second class.

When that time comes, whether it's going back and forth between the sky and the ground, or when the aliens plan to invade the earth, they will have their own preparations.

With their Merrican's strength, they can definitely handle everything when the time comes.

Well, that's what those politicians here thought.

The scientists in the room were a little more realistic, and they were still analyzing the "new generation" of space food.

Judging from the video, the bowl of noodles has a lot of rituals, and these rituals are precisely the taste of the earth.

Well, although the bowl of noodles in the video is indeed a little more tech-high, the production steps are a little more complicated.

However, from the perspective of human emotion, that bowl is not even 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 sea of stars, but the human body is not suitable for the sea of stars.

Weightlessness is the enemy of mankind!

Species evolved over hundreds of millions of years, eventually evolved into humans, adapted to the gravity of the earth, and suddenly had to be made to use gravityless, which is simply embarrassing.

During space flight, astronauts' blood and other bodily fluids do not flow down the body as habitually as they do in gravity conditions.

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

This causes the astronaut to have facial swelling, head swelling, varicose veins in the neck, headache, nasopharyngeal blockage, and an upward shift in the center of body mass.

And it is precisely the human sense of smell and taste system that is here, which is also the common feeling of astronauts who have no taste when eating.

Add to that the fact that the ones are pressed into cakes, frozen to dry, and extremely dehydrated, and they look rather messy, and they don't feel like it's food a lot of the time.

Aside from the original fruits, chocolates, nuts and the like, things don't change, but they don't even feel like they're serious food.

So a lot of times eating is really like chewing toothpaste.

It's not even as good as toothpaste, at least it's still very sour to eat.

Once you don't eat well and are affected by the space environment, the astronauts will suffer.

In the first few days, astronauts 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 sweat, nausea, vomiting, dizziness and other symptoms caused by excessive movement stimulation of vestibular balance receptors in the human inner ear when taking a vehicle, and excessive bioelectricity is produced by the vestibular organs, which affects the nerve center.

Then, my stomach upset and I vomited directly.

If you have a motion sickness on Earth, you can take medication to relieve your symptoms, or even go to the hospital if you can't.

But in space, on the space station, astronauts can't use drugs, even if they cause more serious space motion sickness.

Sometimes it has to be said that astronauts are actually part of space experiments, and even they need to pay the pain to bring considerable experimental data to the entire human community.

Shorten the evolution time of billions of years to a very short, very short, very short, short to ...... 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.

After returning to Earth, it will take them a few months to return to normal.

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

By the time astronauts return to Earth, their immune systems have changed so much that months-long life in space has caused them to lose 8%-12% of their bone density.

This can take up to three years to recover.

In addition, other health factors of space travel include psychological stress, disruption of circadian clocks, extreme temperatures, and ambient noise, which may lead to hearing loss, difficulty concentrating, disrupted sleep, and susceptibility to fatigue.

Astronauts are also exposed to high-energy radiation, which radiates cosmic rays and solar flares from the Milky Way. Long-term exposure to high-energy radiation kills cells and destroys DNA, which can lead to an increased risk of cancer and cataracts.

These are all things that the astronauts knew, or the original astronauts didn't know, because everyone didn't know, so they needed to experiment day by day.

But as space experiments are carried out year after year, a large number of "destructive" consequences appear to astronauts, and the astronauts who later go into space also know about it, but they will still go into space and are willing to be experimenters of human civilization.

There was even a bunch of twin astronauts who did control trials.

One of the two brothers completed a mission in space for almost a year, while the other spent that time on Earth.

After the experiment, the brother in space had many changes in his body and genes, while his twin brother on Earth had everything as usual.

Changes in the space siblings include conditions such as thickening of the carotid arteries and retina, weight loss, gut microbiome changes, cognitive decline, DNA damage, altered gene expression, and chromosomal telomere lengthening.

One of the more surprising is chromosomal telomere elongation.

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

The space brother's telomere lengthening shocked scientists in the Merriken Space Agency's human research program, and even though they don't know why he got telomeres longer in space, scientists continue to study and find out why.

Those scientists want to study ways to extend telomere length as a way to reverse aging or defeat cancer.

The good 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 reduced telomeres were even shorter than before he started the mission.

Let's say that the length of his telomere before was 5, it becomes 7 when it is extended, and it becomes 3 when it is shortened!

Telomere shortening is associated with aging and disease!

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

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

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

The failure of a small subset of genes related to the immune system and DNA repair to normalize also suggests the potential for ongoing damage to human genes due to long-term living in space.

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

This can't be done, so find another way, such as making the astronauts physically and mentally healthy.

And eating is the first issue.

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

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

If you're happy inside, the rest may be better.

And this can allow humanity to go further.
