How to save yourself if you get lost during a spacewalk

They usually carry a compass, and nowadays astronauts basically tie a rope so that they can follow the rope when they get lost.

If you accidentally land on Pluto, you should ask for help from the Earth, and at the same time ask for help from the M78 Nebula, because our Ultraman uncles often pass by there because they want to save the Earth.

There was basically no cell phone signal and nothing to call.

Since there is no reference in space, astronauts can easily lose their sense of distance and proximity, and in this way they can get lost. Far away planets, you may feel close at hand. Normally, a spacewalk will have a rope, and if you get lost, you can follow the rope and go back.

Wake up, wake up, it's time to go to the psychiatric department in the hospital, I guess you have: paranoia.

Just call the robot cat.

Hurry up and catch a bunch of Pluto female aliens, then give birth to a bunch of sons, occupy Pluto, and then come back in their spaceship.

Astronauts can't walk in space, so when I go to space, I ask Dingdong to borrow a bamboo dragonfly, which saves a lot of trouble. And if Ding Dong is in a good mood, he will lend me a random door, then you can go home directly if you get lost. If you don't have a random door, the most important thing when you get lost is to be calm, wait where you are, and ask for directions when the Gundam flies by, or ask Optimus Prime to give you a ride.

Recently, Wukong and Bida have started to fight on Pluto again, and they have been fighting for seven seven forty-nine days, and they have not yet decided the winner, if they enter the Pluto range, the most important thing is to be calm, and at the same time hit ** and go home and tell Mom that they will not come back for dinner tonight, and when they are almost done, you talk to Wukong, and let him use teleportation to bring you back to Earth.

Congratulations, a relentless disease is eating away at the healthy cells of your brain, and a new vegetative person is about to be born!

Landlord, take a shower and get some sleep. Get up tomorrow morning and get the issue out of the way.

Pluto seems to be made of gas, so it's not going to be able to walk on it.

Also, Does a compass work on Pluto? It doesn't seem to have a magnetic field on it, and if it weren't, the compass wouldn't rotate.

If you get lost in space, you will basically starve to death, first of all, we will not adapt to the air in space, and we will not be able to stand it without food and water. The last thing is to call for help, and then go back to land.

If you get lost in space, the only way to escape is to accept your fate, there are planets everywhere, and there are no signs and directions.

Beijing, 1 (Xinhua) -- Astronauts walking in space means entering the high-vacuum and high-radiation environment of space from the atmospheric environment in the spacecraft, which is similar to the ground, and it also means that astronauts have to leave the spacecraft and "walk" alone in weightless space. How to ensure the safety of astronauts out of the capsule?

Chen Shanguang, commander-in-chief and chief designer of the astronaut system, said that the most important safety equipment is an extravehicular spacesuit. Oxygen supply, power supply, air circulation, voice support ......Most of the functions that the spacecraft can achieve are concentrated in a small extravehicular spacesuit. It can be said that an extravehicular spacesuit is a small spacecraft that is worn on the body.

Under the protection of extravehicular spacesuits, astronauts seem to be "exposed" to space, but in fact they are in a small environment with air pressure, atmospheric composition, temperature and humidity suitable for human survival.

In response to the biggest danger in the spacewalk - the leakage of the spacesuit, Chen Shanguang said that all the designs of the extravehicular spacesuit are double backup, or even triple backup. For example, in the event of a leak, in addition to the main oxygen cylinder, the astronaut can also use a spare oxygen cylinder, and even if both fail, there are also ejectors and emergency oxygen supply devices to ensure the safety of the astronauts.

China's extravehicular spacesuit does not have a power plant. So, once an astronaut breaks away from the spacecraft, won't it be easy for him to disappear into the vast space and become a "space trapeze"? Don't worry, astronauts wear "seat belts" on their bodies.

When this reporter visited the extravehicular spacesuit before the launch of the "Shen VII," he saw that two orange safety tethers, one long and one short, stretched out from the lower right side of the cuirass of the extravehicular spacesuit. This is no ordinary rope, they have springs inside them that can be pulled up to a meter and are able to withstand a ton of pulling force. At the other end of the rope are two hooks, and before each step of the spacewalk, the astronaut must first fix the hook of the safety tether on the handrail of the orbital bulkhead, and only after one is fixed can the other change position.

In addition, there is a meter-long "electric umbilical cord" connected to the spacecraft on the left side of the astronaut's waist, which is used to transmit the astronaut's physiological parameters. This feature is completely wireless and we use wired as a backup for the safety tether. ”

Chen Shanguang said: These security measures are also a common practice in international space activities.

Advance planning has minimized the risk!

I'm going to talk about the problem, and you think about how you do it.

1. Environmental impact: low temperature, lack of oxygen, harmful radiation, floating objects and fine dust that may be impacted.

2. There is nowhere to exert force, and it is necessary to solve the problem of the defeat movement.

3. Navigation, and communication between the Nassho faction and the mothership or ground control center.

4. Psychological problems caused by being in the vast dark space.
