Super technology leader

"Although the simulated gravity of 0.3G is much smaller than that of the earth, it is precious in space. We will show you a set of comparative experiments that are not very accurate to let you understand the importance of space gravity~"

Yesterday, after the Tiangong Space Station docked with the New Star Hotel, the astronauts on both sides converged to greet all the audience and ended the live broadcast.

Of course the audience is not satisfied. Not only are they dissatisfied, but also those who know the news later. Others watched the live broadcast at any rate. They didn't even watch the live broadcast, so they could only watch it on the Internet.

After reading it, I was shocked.

The plot in the science fiction movie turned out to be a reality!

There was no news before.

Yesterday, those who watched the live broadcast somehow still had barrage guesses. Some guesses were equivalent to a reminder of "high energy ahead", but those who watched the broadcast faced the "future of science fiction."

When discussing on the Internet, many people incidentally contacted the leader and the Tianxia Space Agency official and asked the official to come up with more related videos. Their friends love to watch.

No, the space agency and Navigator jointly released a video on the second day of the docking.

The five astronauts in the video belong to two different space stations. They each go to each other's space station and experience different environments.

Two astronauts came to Tiangong and experienced with one of the remaining pilot astronauts in the simulated gravity cabin. They experienced running, exercise, eating, working, resting, and going to the toilet under 0.3G gravity. There are four gravity cabins, and each cabin has different functions. Rest, exercise, and work do not affect each other.

The navigator's trainee astronauts didn't have a long time to come up, so I didn't feel it deeply, but the Tiangong astronauts who had been in space for several months were really moved to cry.

Speaking of crying, in the Tiangong Space Station in a completely weightless environment, they would try their best to prevent themselves from crying, because when you cry, the tears don’t flow down. In the end it becomes a water polo.

If you do not use absorbent cotton to suck away the tears in time, your eyes may be damaged.

I can cry now, it is a happy cry, because it is great to experience gravity again in space.

When running on a treadmill, there is no need to tether the rope. As long as the movement is standardized, you can run like on the earth, just a little floater.

You can lie down when you sleep, you can feel the softness of the mattress, and you can cover a thin life without having to find a sleeping bag to tie yourself up.

The toilet of the simulated gravity cabin is really great. Although it still has certain space attributes, it is "heaven" compared to washing in a weightless state.

You can sit steadily while eating, and you don’t have to worry about floating while eating, and you don’t have to worry about food residue flying around or even flying into your throat and making you cough.

It feels good to have a bowl of soup, and it feels like going home.

It is said that the navigators are working on the technology of separating and reusing oil fume and gas. If this technology comes out, they can cook and eat in the simulated gravity cabin of the space station.

Of course, it can be done now, but when cooking fume separation technology is not available, all the fume and exhaust gas produced by cooking have to be replaced, which is too wasteful.

The gravity of 0.3G can do too much, it is almost twice the gravity of the moon. Before, they envied that their counterparts on the moon base could sit and eat safely, but they did not expect that now they can too.

And better.

These explicit benefits are not the most important ones. The hidden benefits are the core driving force behind the development of the simulated gravity cabin.

As we all know, space travel can explore the unknown, experience adventure and excitement, and satisfy human curiosity for novel things.

But this is limited to short-term space travel.

Practice has proved that long-term space flight in a weightless and vacuum environment can cause serious damage to the astronaut's body, such as causing muscle atrophy or cancer.

At present, the longest time that astronauts can stay in space is more than 400 days. In the future space exploration, the time to stay in space will be longer and longer. Therefore, we must understand weightlessness, high vacuum, large temperature fluctuations and high energy radiation. How does the space environment affect human health, and we must overcome them one by one.

Weightlessness will cause changes in cardiovascular function, as I said before, it will become bigger and thicker.

This is 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 will flow back to the chest cavity and head, which can cause astronaut facial swelling, head swelling, neck varicose veins, headache, nasopharyngeal blockage, and the upward shift of the body mass center.

In the first few days, astronauts will also suffer from motion sickness, also known as space motion sickness, which is similar to any other form of travel disease. It means that the vestibular balance receptors in the ears of the human body will be stimulated by excessive exercise when taking transportation.

At this time, the vestibular organs will produce excessive bioelectricity, which then affects the nerve center. Finally, symptoms such as cold sweats, nausea, vomiting, and dizziness appear, as well as stomach upset and vomiting.

If at the space station, or even throw up directly in the helmet, then the scene is called excitement.

On Earth, when motion sickness occurs, drugs can be taken to relieve symptoms, but on the space station, even if it causes more serious space motion sickness, astronauts cannot use drugs, because the space environment will cause various situations, even if they need to be used, It must be a special drug developed for the space situation.

After three months in space, some astronauts will experience muscle atrophy and even lose up to 30% of their muscle mass. It will take months for them to return to normal after these return to Earth.

In addition, space flight will increase the risk of bacterial or viral infections, and even reactivate certain latent viruses in 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, which 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.

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

But things have two sides, and there are both disadvantages and benefits in zero gravity.

For example, some unfavorable conditions for normal people, in turn, can actually relieve some patients' back pain and improve blood circulation.

Therefore, the model embodied in the combination of Tiangong and Starry Sky Inn is both a weightless environment and a simulated gravity environment.

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

When astronauts leave the ground, they leave the strongest 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 thick as the atmosphere that is hundreds of kilometers thick.

The 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 destroy DNA, which may increase the risk of cancer and cataracts.

In fact, Navigator has a new technology almost a day. The bulkhead protection layer of the simulated gravity orbital module is Navigator's new material. The protective capacity of the new material is several times that of the Tiangong and the International Space Station.

In addition, the various new drugs from the Life Science Research Department of Navigator, especially those targeting space radiation damage and enhancing human physique, are also at the most advanced level in the world.

Several technologies work together to ensure that astronauts have better survivability in space.

But those are too far away, and the performance of simulating gravity now has made many people ecstatic.
