How should astronauts return to the spacecraft if they accidentally fall into space?

Now, with the development of science and technology, China's manned aviation industry is also constantly developing, and even we can realize the dream of soaring in space, and one after another manned spacecraft have entered space with people's dreams, making great contributions to the development of science and technology in China. So how do astronauts on a spacecraft get back to the spacecraft if they accidentally fall into space?

First of all, we have to know that the astronaut enters the spaceship, and the surrounding environment and climate are completely different from ChinaIt's very difficult to go back, because there is nothing in space, and there is nothing for the astronaut to grasp and return. Therefore, astronauts who go into space usually take a rope to firmly connect themselves to the spacecraft, so that even if they accidentally break away from the spacecraft, they can use this rope to return safely.

In the early days, due to the limited level of economic development, astronauts only had a safety rope when they went into space to perform tasks, but now with the development of science and technology, astronauts' spacesuits are equipped with systems to maintain the life of astronautsThere is pressure and temperature suitable for human survival in it。Even when it is out of its original environment and thrust, the system can help him return, so there is no need to worry about anything that will happen to the astronauts.

If a real astronaut accidentally breaks away from the spacecraft, then he can now use his high-tech spacesuit, with the help of the recoil system inside, and then fly his body to the spacecraft, and as a last resort, he can also release the gas in the spacesuit first, and thenThe principle of using pressurePush yourself back. However, after so many space operations, there has never been an incident in which an astronaut has ever separated from a spacecraft, and it seems that our country has done a very good job of protecting the lives of these astronauts.

You should contact the staff on the ship to help you get back to the ship, as it will be difficult to return to the ship on your own.

You can use the reaction force to return to the spaceship, and at this time, you can throw objects in the opposite direction, and you will be subjected to the reaction force.

There's no going back. If you fall into space, your body will be **, and you will die.

If you accidentally fall into space, it is basically a dead end, and the chance of survival is very small! That's why we want to survive in space. Because space is a vacuum, there is no oxygen, there is no gravity, and you will slowly float in space, or further into space, or to Earth.

When the astronauts first fell, they were wearing spacesuits with 8 hours of oxygen and a backpack with jet boosters. When you fall for the first time, you can use the booster to push yourself back into the ship, and if the booster fails, it's over!

At this point, you will realize that your body is already in space. If you're less than 30 meters away from the ship, you can use the ship's arms to pull it back, but if you're more than 30 meters away from the ship, you can't grab the arms. Only despair awaits death!

When the air in the spacesuit runs out after 8 hours, you're dead! Or it can drift into outer space for 20 or 30 years, or it can be smashed to pieces by space junk, or it can be captured by the gravitational pull of another planet and become a human satellite of another planet. Or it can be pulled back to Earth by the Earth's gravitational pull, and when it enters the Earth's atmosphere, it creates friction that burns the human body to ashes.

Either way, the results are tragic. Speaking of astronauts, does the body decay? We need to be clear about that.

Decomposition requires oxygen, temperature, humidity, and microorganisms to break down the body. Space is a vacuum, there is no oxygen, and the temperature is low. So the body doesn't break down in space!

Therefore, the life of an astronaut is in the service of the aerospace industry. They have truly contributed to the aviation industry with their lives, and they are real people's heroes! They are real heroes.

It is worthy of all of us to learn and admire! Science and technology will only continue to advance if humanity continues to take risks. The same is true of the exploration of space, of which humanity has never stopped its pace and of being a part of the fact that powerful nations continue to send people into space, and we are proud of them.

There are a lot of unknowns in space, and exploring the unknown means taking a lot of risks. Astronauts are the pioneers of humanity, risking their lives to pave the way for all of humanity. From the beginning of space exploration to the present, 22 astronauts have given their precious lives to explore space.

There are 19 people who died on Earth, the United States"Challenger"It happened just 73 seconds after liftoff**, USA"Colombia"The ship disintegrated in the air 16 minutes before landing**, killing all the crew and leaving no bones, and a total of 14 astronauts died twice**.

Astronauts have to follow certain rules when traveling in space, and they have to follow a specific route. In the event of an accident, it is very difficult to return to the capsule again, which is very dangerous.

Call your teammates and then let your teammates rescue you, and the astronaut will be affected if he falls into space for a long time and does not return to the spaceship.

You can directly click on the alarm on the spacesuit to alarm, or you can directly ask your teammates in the spaceship for help, so that you can return to the spaceship.

The ability to turn on your spacesuit and return to the spaceship, so that you can let yourself go back, and now the astronaut's spacesuit is very capable.

Hello everyone, I'm Erchen. China's International Space Station is gradually improving, and three astronauts have been successfully sent into space under the watchful eye of the public. Judging from the ** sent back by the astronauts, their lives are not easy, because this is an environment in a state of microgravity, when the astronauts go out of the cabin to carry out the mission, they will be tied with safety ropes, and if they are not careful, they are very likely to get lost in space, if this situation really happens, then is there a chance to remedy?

Astronauts are a veritable "high-risk" industry, operating in space full of unknowns, no one knows what will happen in the next second, if an astronaut has an accident during the operation, it will float directly in space, pulled by other gravitational forces, astronauts will drift farther and farther away in space, until they die, disappear into the vast universe, in this case, astronauts may be able to save themselves through the following two methods.

Space is almost a vacuum, the drag is very small, a little force, may fly out a few meters away, so when accidentally out of the spacecraft, you can use the force skillfully.

In the process of throwing things, the body will be subjected to a backward force, and the astronaut will be affected by the force and slowly float towards the spacecraft, of course, this force is very difficult to control.

This method is actually the same principle as the first one, and the strong thrust may be able to push the astronaut back.

The above two are the ways of astronauts to save themselves, of course, they can also wait for the rescue of their companions, and the companions can take a longer tow rope and throw it to the astronauts who need to be rescued accurately.

In the spacesuit, the oxygen in it can be used by the astronaut for 10 hours, the oxygen will be exhausted little by little, and the astronaut will eventually suffocate to death, and eventually become the "garbage" floating in space, or be affected by the gravity of other planets, fall on other planets, and the microorganisms surviving on the astronauts become the beginning of life on this planet, of course, this is just a conjecture, and it cannot be proved feasible at present.

What should an astronaut do if he or she leaves the spacecraft without holding on to it when he or she exits the capsule?

The main thing is a safety rope connected to the spacecraft with a spacesuit, and without a safety rope, the astronaut drifting from the spacecraft has a certain danger. Astronauts leave spacecraft for equipment inspection and scientific experiments to carry out activities, which is called spacewalking. Spaceflight is somewhat dangerous due to the fact that the ship's sturdy shell is less protected.

One of the dangers is that astronauts will not be able to return to the spacecraft after they have left the spacecraft, but there are also the following countermeasures. Secure** connection.

Generally speaking, astronauts will use a safety rope to connect their spacesuit to the spacecraft when they are on a spaceflight, so when they lose their focus, they can use a safe rope to return to the spacecraft. The technical conditions of early spacesuits were limited, and the safety rope during spacewalks was umbilical, which could continuously provide life support for astronauts. At present, spacewalks do not use this method in spacewalking spacesuits due to the distance constraints of the umbilical cord.

Thrust spacesuitsNow, spacesuits for space use have independent life support systems that provide astronauts with oxygen, pressure, temperature, etc., and have a thrust system. For example, the spacesuit used by the U.S. Space Shuttle, equipped with 24 nitrogen thrusters, allows astronauts to easily control their posture and safely return to the spacecraft even if they are completely out of the spacecraft. However, the thruster has a limited amount of nitrogen, and if it is too far away from the spacecraft's orbit, it may not be able to return to the spacecraft.

In this case, the astronaut can only try his best to abandon what he throws at maximum speed and, with the help of the counter-shock, push himself towards the spaceship, in which case he can only expel part of the gases used in the respiratory system, as the protagonist of the movie "The Martian" operates. What if this astronaut didn't have a safety line in place and then floated away? What if you need another astronaut to help at this time?

In fact, from the 70s to the 80s of the 20th century, NASA was thinking about this problem, so they tested special spacesuit propulsion equipment. Such a device would allow the astronaut to control the propulsion and direction of propulsion to return to the space station. This method is suitable for astronauts not far away.

For example, it's okay to leave more than 100 meters, but what if this astronaut is floating? Another approach, recently developed, is the integrated reentry system for spacesuits, in which the spacesuit automatically returns to the ISS with the astronauts.

I watched science fiction movies, when astronauts are out of space, they will make a leash on their waists, even if they accidentally grab it and get out of the spaceship, there is no need to panic, because there is a leash, and he can use the leash to pull it back.

If the astronaut does not hold on to the spacecraft when exiting the capsule, then a rope should be tied to the astronaut's body to prevent permanent separation from the spacecraft, and the astronaut should also be equipped with something similar to a hook that can be shot out in time and then drag the astronaut to the spaceship.

In the end, it will definitely be like in the movie, it will float in the universe, and it will definitely die in the end.

Astronauts are prepared with extremely professional conditions to get out of the capsule, they must have a hook safety rope before they can get out of the capsule, and if there is an accident, there are teammates and their own auxiliary devices to help them correct their mistakes.

If you accidentally fall into space, you must send a corresponding distress signal according to your spacesuit, you must reduce the rate of breathing, and try not to waste the air inside the spacesuit.

When astronauts go on a space journey, they will have advanced science and technology to protect the astronauts themselves. If something unexpected happens, the consequences can be devastating.

If such an event happens, the astronauts can contact the space station by radio and can send someone to rescue them, or they can use the tow rope to save themselves.

You should find a way to contact the staff on the space station and ask for help, because it is difficult to save yourself on your own.

The best way to release the gases from the spacesuit to provide thrust to the body is to stay still and wait for rescue.
