The lesson of the former Soviet Union is that astronauts should carry guns when carrying out space missions, because astronauts should not only fly into space, but also return to the ground. Among them, when the return capsule returns to the ground, due to the influence of wind speed and emergencies, the landing site is prone to deviation, and the astronaut's landing site will be selected in a remote and sparsely populated place when designing. Once astronauts land in dangerous areas, the appearance of guns can improve their survival probability.
Astronauts have long been used to carrying guns, but two astronauts in the former Soviet Union did encounter an emergency when they needed guns.
Beliaev and leonov are astronauts of the former Soviet Union, who returned to Earth after completing their space missions in the 1960s. Everything went well, but on the way back, the spacecraft's positioning system broke down, which made it impossible for ground rescuers to accurately judge their position. Unfortunately, the two astronauts landed in a virgin forest in the former Soviet Union.
At that time, there were many bears living on the earth, and they met a bear who came out to feed here. But fortunately, they learned the experience of living in the wild, escaped the bear, and survived in the virgin forest for one night without any protection.
The rescue team found them the next day and protected them from the virgin forest. In the end, they left here with a narrow escape. However, this incident also reminds people how to protect the safety of astronauts after returning to Earth.
Because the space mission is full of dangers, any danger may lead to the death of astronauts, so people put some astronauts' survival supplies, such as guns and knives, in the return capsule. China astronaut Yang Liwei has tents and other materials in his return cabin.
Astronaut's return cabin In fact, the astronaut's return cabin is also specially designed. The last problem that astronauts face after carrying out space missions is the problem of safe return. This is because there is an atmosphere on the earth, and the atmosphere is dense. When astronauts enter the earth's atmosphere in the return capsule, they will generate high temperature due to friction with the air, which will easily lead to the death of astronauts.
At first, the United States designed the space shuttle, and astronauts returned to Earth by space shuttle after performing space missions. Unfortunately, the accident rate of the space shuttle is very high. Two space shuttle crashes in American history killed 14 astronauts.
In addition, the flight cost of the space shuttle is very high, about 500 million US dollars for one flight, far exceeding the design cost. And the aging speed of the space shuttle is very fast.
Therefore, the space shuttle was later cancelled and the return capsule was used as a device for astronauts to return to Earth.
The return capsule is also called the astronaut's cab. When astronauts perform outer space missions, they will enter the earth in a return capsule. There is a heat insulation layer on the surface of the return capsule, which can ensure the temperature in the capsule even if the friction between the return capsule and the air produces high temperature. After the return capsule enters the earth's atmosphere, it will open the parachute. There are at least three parachutes, namely, a guide parachute, a deceleration parachute and a main parachute. The fourth parachute is a backup umbrella.
These parachutes will slow down the speed of the return capsule and eventually land on the surface of the earth. At present, most countries in the world will use the return capsule as a device for astronauts to return to Earth. If the capsule lands on the ocean, astronauts are not allowed to leave the capsule unless necessary. If astronauts land on land, they can use the return capsule as a refuge, and they can use guns or other daily necessities to survive in the return capsule.
Guns can not only prevent the invasion of wild animals, but also make fires, hunt and send signals, so guns are one of the essential items for astronauts.
The conclusion is that China astronaut Yang Liwei carried a gun when carrying out a space mission, not to deal with aliens, but to deal with uncertain landing sites on the earth.
Some countries have made special guns for space, but in China, astronauts usually use small automatic pistols.
