What if an astronaut loses his grip on the spaceship when he exits? What will happen?

We should all be aware that there is a sharp thing at the top of modern spacecraft called the escape tower, but at that time the Soviet Union's "Ascent 2" spacecraft was not equipped with any tools for astronauts to escape, including the escape tower.

Spacewalk, also known as extravehicular activity, is a very key technology in manned spaceflight, and its mastery is of great significance to human's future space activities. On the one hand, spacewalks are for building space stationsIt lays the foundation for other space activities, because while space station construction missions have been replaced to some extent by robots, there are still some aspects that require astronauts, such as repairing and inspecting the spacecraft or station, replacing battery components, and performing scientific experiments.

Therefore, the jet pack is only an auxiliary measure in addition to the safety rope, which is an emergency function. In addition to the test function, the world now does not allow astronauts to use only jet packs to spacewalk, after all, too risky.

In order to overcome the deformation and expansion of the spacesuit, astronauts have to wear a beltChina's space station technology and crew technology are booming, so we will see three astronauts spend three months on the space station. The space station has enough living and working space for astronauts to stand or lie down.

2, in weightlessness conditions, the human muscle mass will be reduced, the heart rate will also slow down, thereby reducing the burden on the heart. It goes without saying that living in space prolongs life. With the development of space medicine, there are a lot of data that spaceflight has a profound impact on the physiological function and metabolism of the body, such as astronauts' weight loss, vestibular dysfunction, and cardiovascular system functionDecreased water and salt metabolism and nitrogen metabolism disorders, muscle atrophy and bone salt loss and so on. How astronauts live in space in several aspects: breathing, walking, eating, bathing, defecating and brushing their teeth.

Space science and technology light tips

This exhibition area is a place for interactive science popularization, technology display and experience of future technological development. It takes the cutting-edge development of modern science and technology as its theme, showing people the prospect of future science and technology and the relationship between science and technology and human life. In the Light of Technology exhibition area, you can go deepLearn about the latest developments and applications in the four major fields of information technology, materials and energy technology, biotechnology and aerospace technology.

Plug tips Why do electric fans, washing machines, refrigerators and other household appliances mostly use three-wire plugs? What is the difference between three-wire plug and three-phase plug? Three-phase electrical appliances refer to three different firelines, and the voltage between each of them is 380 volts, which is generally used for power systems, and is mostly seen in industrial electricity.

The content of science and technology tabloid should be science and technology as the theme, you can collect all aspects of science and technology knowledge or questions and answers to do science and technology, involved in the leadField is very broad, such as astronomical science and physical science and chemistry science and geography, and so on, so, the related contents belong to the category of science and technology in making technology copies out the newspaper from time to time.

Do astronauts have different colors of clothing for different purposes? Can you tell me about it?

The white spacesuit is the clothes that astronauts wear when they walk in space. This suit can keep the astronaut's body at the right temperature in spaceIt provides oxygen, also prevents small debris in space from harming astronauts, and astronauts can also drink water in space. The white suit is much thicker than the orange one because it has a lot of insulation inside. During spacewalks, astronauts have a rope attached to the space station. Therefore, the blue cabin overalls are mainly for the convenience of astronauts living and working in the space station. The suit is very lightweight and has no special functions other than the use of high-tech flame-retardant materials, which is because the station's life-support systems are already so completeSo you don't need to worry about the astronaut's suit.

In case of accidents, the orange suit is also equipped with various medicines, radio talk, lighting facilities and simple food. White spacesuits are called Extra-Vehicular Activities and you can see all the astronauts wearing white spacesuits on space missions.

The reason why astronauts wear white clothes Wireless astronaut : White has the widest spectral range, thus determinedIt has good anti-radiation function and the lowest thermal emissivity. Astronauts in space are directly exposed to various types of cosmic rays and intense solar thermal radiation. Usually living on the ground with atmospheric protection, all kinds of cosmic rays harmful to the human body are absorbed by the atmosphere.
