The temperature difference between the moon is as high as 400 degrees, so why can American astronaut

The temperature difference of the moon is as high as 400 degrees, and the temperature can be as high as one or two during the day, and then it can also reach minus one or two at night when the sun is not in the sunOf course, this temperature difference is impossible for normal people to survive, because the human body can no longer withstand minus 50 degrees and minus 50 degrees without any protective equipment. <>

Taoyuan can survive in such a place because they have a protective suit called a spacesuit, because this is the most basic life system, it can be said that the spacesuit is a small ecosystem, it itself comes with a constant temperature system, oxygen system, and then a variety of living environments that meet the normal characteristics of human lifeTo survive in outer space, landing on the moon or out of the capsule requires the protection of a spacesuit, and even in a rocket spacecraft, the help of a spacesuit is needed, because the rapid impact force inertia requires the help of this external device. <>

The human body itself is actually very fragile, because people themselves do not have any particularly powerful abilities, and the only advantage that people have is that people have smart brains, and people can make all kinds of sophisticated instruments, so that these instruments can help us. When we explore space, we will definitely not be able to fly on our own, and it is impossible to enter space, so we invented rockets, and in order to adapt to the outside environment, we invented space servicesWe have built a space station to be able to survive in space, and we have all kinds of space food, which are all manifestations of human ingenuity. <>

It has been decades since I landed on the moon, and it can be said that human beings now know more about the moon, because after all, the moon, as the only satellite of the earth, is relatively close to the earth, and then there are a lot of materials for reference, so the difficulty of landing on the moon is not so highBut humanity is now preparing to gradually land on Mars, which is an unknown world, and I believe that we will get more information about the universe from the unknown planet.

A few days is for a few days on Earth, 75 hours is equivalent to a little more than 3 days on Earth, but it takes about an hour for the Moon to rotate around a week, that is, a day on the Moon is about 27 days on Earth, and these 75 hours on the Moon can be completely daylight, in fact, the United States landed on the Moon as well.

Because astronauts have spacesuits that can withstand huge temperature differences.

Both the Moon's rotation and revolution period are 27 days, but the Earth revolves around the Sun because the Moon revolves around the Earth. This results in the Moon's diurnal cycle being slightly two days longer than its rotational cycle. In other words, the moon has a little more than 29 days and nights.

The moon rotates once or around the clock, and its day and night are about 15 days each.

Because they have spacesuits made of special materials that can withstand such large temperature differences.

Because astronauts' clothes are made of special materials, they can regulate the temperature well.

Because astronauts will have special clothes, clothes can regulate the temperature well.

The material of the clothes determines how long the astronaut can stay, and the material is resistant to high temperatures or normal temperatures after wearing.

We all know that the moon has no atmosphere on it, so this causes its surface temperature to be very cold, and when it comes to the coldest place in the solar system, friends may think of Pluto and Neptune and other celestial bodies that are far away from the sun.

Since the Moon revolves around the Earth, the Earth revolves around the Sun.

The Moon is a satellite of the Earth, and the geography of the Moon's surface is very complex. After reaching the summit of the moon, they will put on a spacesuit to work. It can be insulated from the cold.

This is because the American astronauts were well prepared before the moon landing and had some special equipment and machinery, so they were able to stay for several days.

Because they have some special equipment that allows them to maintain a constant temperature that can stay for days.

Clothes are very special, and it is also because their clothes have the function of heat insulation, so such a phenomenon can appear.

One of the longest landings on the moon was Apollo 17 on December 11, 1972. This time, the astronauts stayed on the moon for 75 hours, which is equivalent to more than three days of human time. For the Moon, this time is completely insignificant.

The Moon must rotate at a constant speed for about 655 hours, which is equivalent to nearly one month on Earth. In other words, the astronauts spent 75 hours on the moon, completely in broad daylight.

The time it takes for the earth to rotate at a constant speed is about 23 hours and 56 minutes, so 24 hours is equivalent to one day. This is not the case with the Moon, which rotates at a constant speed for about 655 hours, and it takes 655 hours to complete a one-day cycle. 75 hours on the moon is equivalent to 2 hours on the earth, so astronauts did not stay on the moon.

The temperature difference of 400 degrees Celsius has nothing to do with the astronauts, and the time range of the astronauts is broad daylight, and the temperature difference will not be harmful at all.

The temperature of the Moon refers only to the surface temperature measured by instruments, not the temperature of the cyclone and the temperature of the experience. Since there is no gas on the Moon, the temperature of the Moon cannot be measured. Just like the earth where we live, the surface temperature is 70 or 80 degrees, and the temperature is probably only 40 degrees Celsius, which is very far apart.

And the astronaut's spacesuit must be closed through a unique design scheme, and it is very likely that there will be a thermal insulation design scheme and temperature adjustment. In other words, the surface temperature of the moon does not count at all for astronauts. Maybe they just feel a little hot on the soles of their feet, and they don't have any other dangers to themselves.

Since there is no gas on the moon, there is no temperature transmission on the moon, which immediately causes a very large temperature difference on the moon. The surface temperature can reach a maximum of 130 in the daytime and at least -180 at night, and the distance between the middle is particularly large. And the rotation period is too long, and the sun is facing or carrying the sun for a long time, resulting in a very large change in temperature.

Because astronauts wear thick spacesuits when they land on the moon, and these astronaut slow suits can ensure that the astronauts' high-end bodies are healthy, so they can stay on the surface of the moon for so long.

It is because the astronaut Ki Lulu is wearing a spacesuit, and then the spacesuit can make the astronauts feel the normal temperature on the earth, so the astronauts can stay on the surface of the moon for many days.

Because they have some special protective clothing, these clothes can better balance the temperature and keep the human body in a normal state.

Because the American astronauts wore spacesuits, which were very well insulated, it was fine.

In fact, according to some information, the temperature of the United States when the moon landing was indeed not high, and the spacesuit was enough to bear it.

The spacesuit is resistant to high temperatures, low temperatures, and fire resistance, and has a vacuum insulation layer, the outermost protective layer, a slightly inner liquid-cooled suit (for heat dissipation), and a suitable layer of underwear for the innermost layer, so astronauts will not feel uncomfortable wearing spacesuits in space.

In fact, because the astronauts wear spacesuits, they can withstand radiation and temperature, as long as they are around the moon, they will naturally lower the temperature.

The extravehicular spacesuit is resistant to high temperature, low temperature, and Qihong radiation, and has a vacuum insulation layer, the outermost protective layer, a slightly inner liquid-cooled suit (for heat dissipation), and the innermost underwear comfort layer, so astronauts will not feel uncomfortable wearing spacesuits in space.

Because astronauts have special equipment, wearing that suit can effectively prevent the effects of large temperature differences.

Humans are the most sensitive animals to temperature changes. Currently, the normal body temperature of humans is 37 degrees, and as long as it is high, the human body will have a fever. So if there is a temperature difference of 400 degrees, how can humans survive?

We know that the Moon does not have the thermal insulation of the atmosphere, so it is directly irradiated by sunlight and cosmic rays, resulting in a huge temperature difference on the Moon. During the day, the temperature on the moon can reach as high as 120 degrees Celsius, and water can boil directly on the surface of the moon. At night, the temperature of the moon drops to minus 170 degrees.

In this case, humans cannot survive on the moon.

So how did the U.S. Apollo program resist such a temperature difference on the moon?

In fact, the U.S. Apollo program has carried out six manned missions to the moon, sending 12 astronauts into space. The 12 astronauts walked on the moon for a total of 22 hours and stayed for more than three days. The only way astronauts can withstand the extreme temperatures of the moon is the spacesuits they wear.

The spacesuit worn by the American astronauts to the moon, called the A7L spacesuit, weighs 80 kilograms and uses 21 layers of material inside to protect the astronauts from extreme temperatures. The outermost layer of the spacesuit is PTFE resistant to high and low temperatures, which can work in temperatures ranging from 250 degrees Celsius to minus 180 degrees Celsius for a long time, providing the basic conditions for astronauts to withstand extreme temperatures. In addition, the spacesuit can provide the astronauts with the materials necessary for life support, such as maintaining a certain air pressure, providing oxygen and absorbing carbon dioxide.

To solve the problem of convenience for astronauts, special bags were specially equipped.

Under the protection of such spacesuits, astronauts were able to stay on the moon for such a long time.

But in reality, the trials that astronauts experienced on the moon were not the worst, because the astronauts on the moon mainly experienced daylight, and none of the astronauts experienced the dark night of searching for relatives. Although the temperature difference on the moon is huge, the moon's day and night change time is also very slow, we are a day and night in a day, and January on the moon is equivalent to a day on the earth, and the whole day lasts for about 15 days. Each time it goes to the moon, NASA chooses the right time for the astronauts to leave Earth before the moon "sunset."

Although PTFE claims to be able to work at temperatures as low as minus 180 degrees, U.S. spacesuits should not have taken into account the extreme cold on the moon, and it is difficult for all current spacesuits to have the dual properties of high and low temperature resistance.

For China's lunar exploration, manned lunar exploration has always been part of the plan, and I don't know what kind of surprises China's spacesuits will bring us in the future.
