Second, you can throw things in a forward direction.This method also uses the opposite force to push oneself close to the capsule, and those who have studied physics know that the force is mutual, if we hit an object with our hand, the object will also give the hand a spring. If an astronaut throws an object forward, according to the law of conservation of energy, it is the same energy as his own retreating.
Find a place with sun, preferably a high point, and keep sending sos. And say a prayer to the unmasked God. This is the case with today's technology. In the old days, you'd find a cool place, take the coolest pose, and then take off your spacesuit, likeIf you have one of those things. After a long time, this kind of thing is almost impossible.
But if the power line still breaks, the astronauts will have to use the "extra-vehicular activity simple rescue device." This is a small emergency jetpack system, worn during spacewalks, that provides free flight power back to the space station. But if the device goes awry, or if the astronaut wearing it loses consciousness and cannot operate the jetpack, the only hope is for the rest of the space station crew to organize a rescue mission.They usually carry a compass, and today's astronauts basically stillCan tie a rope so you can follow it back if you get lost. If you land on Pluto, you should call for help from Earth, and also call for help from M78, because our Ultraman uncles often pass by there to save the Earth. There's basically no cell phone reception, nothing to call.
If the tow rope accidentally broke, the astronaut would fall into space, so someone asked: if the astronaut accidentally fell into space, how to return to the spaceship? Maybe there are two ways to try it. If an astronaut accidentally falls into space, he or she becomes directionlessFloating objects will float down and down in space until they are attracted by the gravity of other objects.
1. The official notice of the first exit of the God 14 crew has come. What are the precautions for the astronauts to carry out the exit activities? Liu Yang and Chen Dong successfully got out of the capsule on September 1 and took photos with the earth, and the details of the space suit have changed, which is called Chinese romance by netizens. Chen Dong said out of the cabin feelingAll right, Chen Dong and Liu Yang are out as Shenzhou 14. 2, in the middle of April, three astronauts will return to the Earth by the re-entry module, followed by China's Shenzhou 14, 15 manned spacecraft will be launched one after another, continue to complete the full construction of the Tiangong space Station before the preparatory work. At present, the three astronauts on the space station are working intensively to make various preparations.
3, Shen14 astronauts into Tianzhou 4, they have to complete the task is difficult. For example, conducting space science and technology experiments. Such a mission can root the scientific spirit in young people, but also let reasonOn getting practice. Secondly, they must cooperate with the docking of the sky experiment module, the core module and the Dream Sky experiment module, and complete the assembly and construction of the Chinese space station in orbit. In a low-pressure environment, they have to overcome various environmental factors to complete the task.
4, the Shenzhou-15 astronaut group has selected Shenzhou-14 and Shenzhou-15 two crew groups will be in orbit for six months, will be the first time to realize the rotation of the in-orbit crew, to achieve uninterrupted presence. The six astronauts in the two crew groups will stay in orbit for 5-10 days, and the astronaut system will face more severe challenges.
5, Shenzhou 14 will also welcome Shenzhou 1They establish a distance communication. He is also far from home, discussing with his teammates how to live on the space station, which is less than 139 square meters.
You can try to live like an astronaut. Despite not floating in weightlessness, performing any groundbreaking experiments, or seeing the Earth from space, you can stay at home for a few days, working indoors, exercising, and eating only freeze-dried food from a packet. It's an exploratory attempt to understand what it's like to live isolated and confined to the same place 24 hours a day.
In addition to activities inside the capsule, they are often required to perform tasks outside, such as repairs. For space, this is not an easy job, because the spacesuit is so heavy, a simple movement often takes a long time to complete. So the "space walk" will last six or seven hours, and the diaper has become a standard part of the spacesuit.Psychological training The third kind is psychological training, astronauts not only have a strong physical quality, but also need to have a strong psychological quality to be able to go to space. Because once in space, astronauts can be far away from people and lonelyIsolated from the rest of the world, being alone in a confined space is subject to two major physical and mental challenges.
First of all, to have undergraduate study experience, you need to accept the knowledge of science, medicine, engineering and other fields; Second, you must have operational experience, especially as a test pilot. Third, good astronauts are good at helping others." After the spaceship enters the space, it is far away from the people, in addition to contacting the ground, isolated, and the long-term lonely life has a certain impact on people's psychology and physiology.
Have at least two years of relevant professional experience in a STEM field, or have piloted at least as a captain1,000 hours of jet flight. Can pass NASA's astronaut fitness test.
4, How astronauts live in space When astronauts eat, they have to suck with their mouths and squeeze with their hands like a baby. Washing up in space is even more fun. Instead of brushing your teeth with a toothbrush and toothpaste, you chew a gum, which is similar to gum, and let the dirt on your teeth be on the glue to achieve the purpose of cleaning your teeth. Wash your face without water and towels, just wipe your face with soaked toilet paper, andPut this wet paper on the comb and brush your hair.
