What happens if an astronaut accidentally drifts into space?

An astronaut accidentally drifted into space? This is something that many people don't want to see happen, but Magnesium Kejun still objectively analyzes it first, what will happen? I saw a video of an American astronaut coming out of the capsule, and I was thrilled.

The requirements for the space capsule are very strict, one person out of the capsule and one person supervises. Once, the hook of the American astronaut out of the cabin did not hang outside the floating cabin, and at the last moment, another astronaut grabbed his foot and pulled him back, avoiding an accident. It's dangerous!

If an astronaut drifts into space because the safety rope breaks, and the jetpack malfunctions, and your astronaut buddy can't come out to save you, you'll drift away in the direction of the force you were exerting when you loosened. You'll be completely weightless and probably spin all the time. No matter what you do, your body movements won't save you.

Earth's gravitational pull will trap you in a certain orbit around the Earth, if you have a spacesuit.

Intact, you'll experience a terrifying 8 hours waiting for oxygen** to run out.

There is another situation, once your spacesuit is damaged, your ** will be exposed to space, and the blood in your body will be due to the lack of atmospheric pressure.

And boiling, causing the body to swell, and even self-explosion. If you go into space at just the right angle and in the right orbit, you'll crash into Earth. But you can never reach the Earth, because of the atmosphere around the region.

It will make you disappear completely, like a shooting star.

Of course, we don't want that to happen, and for this reason the space agency has taken full measures to ensure the safety of astronauts. When astronauts walk out of the ISS.

When carrying out the operation, they must be at all times with the spaceship.

Connected by a 26-meter-long multi-strand braided retractable steel rope with tensile strength.

Up to 1100 lbs.

But if the rope is broken, the astronauts will have to use the "extravehicular activity simple rescue device". Fly freely with the power of a jet back to the space station or spaceship.

Here, we pay tribute to the astronauts flying in space! Salute to China's aerospace heroes!

If an astronaut falls into space, all that awaits is tranquility and death.

What does it feel like to be in space?

The astronauts who have had the most say on this issue are probably the astronauts who have been to outer space. We can learn a thing or two from my country's aerospace hero Yang Liwei:

At 590 seconds, the spacecraft accurately entered the predetermined orbit, and I suddenly felt my body about to float, and I realized that the spacecraft had broken away from the Earth's gravity, and I had really come to space. Suddenly, I felt as if I was head-down and toe-up, and I felt very uncomfortable. I realized that this was an illusion that appeared in the weightlessness of space.

I used the usual training methods to force myself to fight and overcome this illusion in my consciousness, and I quickly adjusted and returned to normal.

When I came to the vast expanse of space, I saw a magical and wonderful scenery. Outside the porthole, the sunlight illuminates the spacecraft's solar sail panels, and below is the beautiful earth that has been inhabited by humans for more than 10,000 years. The blue Earth is covered with faint clouds, and the long coastline is clearly visible between the continents and the oceans.

The spacecraft flies around the earth at high speed, every 90 minutes, one day and one night, between black and white, the edge of the earth seems to be inlaid with a beautiful gold edge, and the scenery is very charming.

The first thing you will do is face a weightlessness that can make you dizzy, and you may also have some hallucinations. Since the environment in space is completely different from that of Earth, people can feel upside down, suffering from dizziness, loss of coordination, and loss of appetite. If there are no professionally trained people, then this state will continue for a long time.

Thanks to the protection of the spacesuit, the astronaut will not burst due to the difference between the pressure of the human body and the pressure of space. But survival has indeed become the next issue that must be faced, and although it is in space, the metabolism of astronauts does not stop because of this. Also, the air, the oxygen that the spacesuit comes with is limited, it can only support a few hours.

Then it is likely that the astronaut died of suffocation before he even felt hungry.

In the vast universe, even if scientists on the earth find floating astronauts with living characteristics, they are helpless, not to mention how long it takes to prepare for the launch of a rocket and how much it costs, it is impossible to accurately "fish" people back in space with current technology.

Astronauts at this time will be very dangerous, because they may be sucked into black holes, and they may also be swept into other celestial bodies.

It is a very dangerous thing for an astronaut to accidentally drift into space, the edge of space is infinite, and it is easy to run out of astronauts' energy.

We all know that today, human beings can play happily on the earth, and everything in nature is safe and smooth enough to circulate and evolve on the earth, which is inseparable from the attraction of the earth to us. Because of the gravitational pull of the Earth, we didn't fall into the universe and become space junk. Do you know why planets in the universe, including the Earth, can be suspended in the universe without falling?

In fact, there is no air in the universe, all planets are in a vacuum, and there is no gravity on the planets themselves, and there is no difference between them. All planets are weightless, so there is no problem of falling matter in the universe. This is also the reason why astronauts levitate in space.

Moreover, in the universe, each planet does not move in no order, due to the impact of the universe, all the planets have accelerated, and under the condition that there is no air resistance, all the planets follow the laws of the universe. And because in the universe, all matter is endowed with energy from the moment of birth, and these energies make the planets have different attractions to each other, resulting in a state of bondage or bondage, so there is a situation where planets orbit stars and satellites orbit planets in an orderly manner.

However, there are times when this situation can be broken. When a planet's energy is exhausted, the planets around it are no longer bound by the gravitational attraction and fly out of the original trajectory to the system, and if you are lucky, you may be attracted to other planets and become a member of other systems, and if you are unlucky, you may become space junk or be swallowed by a black hole.

In reality, people also need to be prepared for space flights and space expeditions: for example, in order to prevent food from floating around in the spacecraft module, space food is processed into small "bite" food, and there is no flowing soup in the food package.

In the early space flights of the former Soviet Union and the United States, astronauts adopted a "mouth-to-mouth" feeding method, that is, specially processed liquid or semi-solid food was packed in a container similar to a toothpaste tube, and the food was squeezed directly into the mouth through a catheter when eating.

Because there is no gravitational force around space, and gravity is even less. Space is not affected by gravity at all. So the astronauts are in"Weightlessness"status. Therefore, it will float in the air.

Astronauts in outer space, without the gravitational pull of the earth or other planets, without the action of external forces, are in a state of weightlessness, so they will float in outer space.

It is nonsense to say that there is no gravity or is not affected by gravity, and astronauts float because they move in a uniform circular motion around the earth, and gravity is the centripetal force of uniform circular motion, keeping a specific height constant. If there were no gravity, astronauts would have flown out of Earth's control along tangents long ago.

Because there is no gravity in space, without the gravitational grab, of course the little people in space will float up like catkins.

The Earth can be suspended in space, what is the reason exactly?

Something very bad can happen, because there is no air there, and astronauts can die.

Then it will be very difficult for them to fly back and die in space, after all, space is very dangerous and there are no living conditions.

You will lose weight, your body will drift around, you will not be able to eat when you eat, you can only eat some compressed food, and you need to send oxygen in space.

Loss of consciousness due to lack of oxygen. In the 1965 air chamber experiment, an astronaut who was accidentally exposed to a vacuum said that due to the sudden drop in pressure, he felt the saliva on his tongue begin to boil, and he passed out after about 14 seconds, but the researchers noticed the situation and took measures at about 15 seconds, and the astronaut gradually regained consciousness.

Any place in space is full of gas, dust, wind, photons, cosmic rays and other substances from the stars, and there is no way for humans to survive in this environment, if humans are exposed to space, they will lose consciousness within 15 seconds, and at the same time, due to the low pressure, the air in the lungs will expand, the tissues will begin to tear, blood and saliva will begin to boil, and they will die in a few minutes.

Astronauts rely primarily on the space station to breathe in space

There are generally two types of air from the space station, one is the air from the earth, and the other is the space station's own production. The ISS has a well-developed system of oxygen replenishment and air filtration, all of which are configured according to the composition of the air on Earth.

This system is mainly through the method of ionizing this water, generating oxygen and releasing it directly into the space station, and the hydrogen and oxygen can also be reused without pollution. The spacecraft cabin is equipped with an air circulation and infiltration ring system, a spacecraft environmental control and life support system, which creates a living environment close to the ground atmosphere for astronauts in the sealed cabin.
