The United States has always been at the forefront of the world in the field of space exploration, and it has also encountered difficulties in exploration.

When it comes to astronauts, almost everyone is like a "space hero" in their hearts, but the space environment is unpredictable, and human exploration of space is only the tip of the iceberg. When performing missions in space, astronauts face a variety of problems, but what difficulties do they usually encounter?
As we all know, there is no gravity in space like on Earth, and the absence of gravity makes everyday life the primary problem that astronauts must overcome.
First of all, there is the problem of eating, in space, the tableware used to eat is made of special materials to prevent the food from accidentally running away, and special tables will be configured. The most difficult thing is to drink water, water is not flowing in space, and the water in the cup will not flow out under the influence of gravity like in the earth, and it is very difficult to drink water.
Then there is the issue of hygiene, the time astronauts spend in space is increasing with the growth of technology, and people are more likely to sweat in space than on the ground, so it is also very important to keep themselves clean. But it is not easy to wash, under normal circumstances, astronauts will be equipped with a special oral cleaner in space, this cleaner is like chewing gum, astronauts can put it in their mouths and chew it after eating, you can achieve the effect of cleaning the mouth. Body hygiene can generally be scrubbed with a wet towel or using dry cleaning to scrub the whole body, when you have to use water is quite cumbersome, on the one hand, water resources are limited, on the other hand, water will float in the air, which will also bring a certain danger to people, once choking into the human throat, it will cause life danger, so when bathing, astronauts will also wear breathing masks, eye masks, etc. to prevent water droplets from entering the body.
For astronauts, the space environment is extremely harsh, and long-term work in outer space will cause human muscles to atrophy, which is very demanding for the body, and then there is the lack of oxygen in the space environment, cosmic radiation and other factors, which will bring damage to the human body.
-
When astronauts perform tasks in space, they generally encounter weightlessness, because if they can't borrow strength in space, their actions will be particularly inconvenient, and they will usually encounter difficulties in drinking water and eating, cleaning their mouths, and bathing and washing their faces.
-
You will encounter difficulties in eating, sleeping, and defecation, like getting out of the space capsule is quite simple, and the process of going back is very difficult to walk on the moon, in this mission, in fact, there is a certain difficulty in doing anything, it is difficult to operate, and it will not be as simple as on Earth.
-
Generally, you will encounter the environment is not very adaptable, blood weightlessness, difficulty in physical exertion, diet is not guaranteed, the air is not fresh, you will feel inconvenient to move, etc.
-
Astronauts will encounter difficulties such as eating, moving, sleeping, drinking, bathing, etc., and they are all particularly dangerous, and astronauts are also very hard.
-
It is very likely that they will drown in space, and there will be drifting away, and the blood of the whole person will boil, and it will cause the whole person to be exhausted, and there will be many unknown difficulties waiting for these astronauts.

Introduction: In fact, in the process of space exploration, people have made breakthroughs again and again, for example, from sending objects into outer space, to people entering outer space in the space capsule, to people going out of the capsule for spacewalks, and then to landing on other planets, so each breakthrough represents people's space exploration, and has made great progress. So when was the first human spacewalk?
What are the difficulties of a spacewalk?
In 1965, humans went out of the capsule for the first time to enter a spacewalk, and it was Russian cosmonauts who walked out of the capsule, so it is said that the time for human beings to carry out spacewalks is relatively early. However, not every country can do this, and there are still relatively few countries that carry out spacewalks, and in fact, there are difficulties in conducting spacewalks. Because the environment inside and outside the capsule is completely different, for example, astronauts will not worry about radiation and other effects of outer space in the space capsule, but you must know that outer space is basically zero gravity and zero gravity, so once the astronaut and the capsule lose connection, then they will float in the capsule.
The temperature in outer space is very low, which means that if there is no spacesuit to protect it, then the astronaut will quickly freeze to pieces. And there is no oxygen, so it has to be supplied through oxygen cylinders. At the same time, it is important to note that there is a lot of solar radiation in outer space.
In fact, the development of space exploration can be seen in terms of the progress of mankind as a whole and the progress of the country. China's space exploration is definitely at the forefront of the world, and the investment and results have been relatively good, leaving many countries in the dust. Not only that, but it has also built its own space station, so in the process of space exploration, it is actually a time to show the country's scientific and technological strength and economic strength.
In addition, space exploration can also bring more productivity and development space, and in the process of space exploration, it can also explore the path of commercialization, so that the life of people on the earth can be better promoted.

March 18, 1965.
Difficulties encountered:
1.Drowned in space. A spacesuit, like a small personal spacecraft, will fail. Any system that fails is life-threatening.
2.Float away. During spacewalks, astronauts will tie 26 meters of steel rope to their bodies to prevent them from drifting away.
3.Blood boiling. Astronauts wear spacesuits during spacewalks to protect them from the vacuum. Human flesh expands to twice its normal size in a vacuum, and spacesuits protect it.

The first actual spacewalk was on March 18, 1965. The difficulty that Fu Chunpi will encounter when walking in space is that it is difficult to walk, he cannot control his own pace, he cannot control his body, he cannot walk on the ground, and he will be affected by atmospheric pressure.

If you go to space the way you live on Earth, there will definitely be a lot of big jokes:
1. When drinking water, if you use an ordinary cup, even if you turn the cup upside down, the water will not flow down. Because in a spaceship, the water loses weight. To get water, astronauts use a plastic cup with a straw.
2. Walking in a spaceship is more fun. A person will float into the air with the slightest exertion, and a cough may take several steps back. In order to be able to walk smoothly, the astronauts wear shoes with hooks on the soles of their shoes so that they can be firmly hooked to the grid floor.
3. Taking a shower in a spaceship is not an easy task, and the water sprayed from the nozzle is always floating in the air. To solve this dilemma, scientists have designed a special shower.
4. Space food is sufficient, complete and nutritious, but astronauts can't eat in the sky.

The difficulties in exploring space are: the obstruction of gravity, the lack of thrusters, the absence of oxygen in space, the absence of space positioning systems, the lack of folding technology for humans, and so on.
1. The obstacle of gravity, there is no gravity in space, and human beings cannot walk in space normally.
2. Lack of thrusters, human beings lack high-speed warships, and after entering space, the speed is too slow, and it will not be able to get out of the round and collapsing galaxy for a hundred years.
3. There is no oxygen in space, and human exploration of space can only rely on spacecraft to store oxygen, and cannot produce oxygen in space and breed animals and orange plants.
4. There is no space positioning system, and although stars can indicate directions, they are too far away to locate the spacecraft.
5. Human beings do not have folding technology, that is, the technology that the mold can be folded on a curved surface and then quickly shuttled, etc.
Space is the cosmic space outside the Earth's atmosphere, the entire space outside the atmospheric space. Physicists divide the atmosphere into five layers: the troposphere (sea level up to 10 km), the stratosphere (10 40 km), the mesosphere (40 80 km), the thermosphere (ionosphere, 80 370 km) and the outer atmosphere (ionosphere, above 370 km).
The difficulties encountered by the Red Army in the Long March can be described as many, mainly as follows: 1The enemy's encirclement, pursuit, and interception, hundreds of thousands of troops on the ground blocked in front, chased behind, and intercepted left and right, which relied on the Red Army and the enemy to fight bravely, that is, to fight, that is really called a killing to open a bloody road, to seize the road; After the Zunyi Conference, under the leadership of Mr. Mao Gongzedong, our army fought, fought well, walked, walked wonderfully, took the initiative everywhere, and finally completed the Long March victoriously. >>>More
Density is an inherent property of an object, which does not change with changes in the environment, that is, the density of an object does not change in space.
I will not ask for help from relatives.
I have a very bad relationship with my relatives, because I think my relatives are some abnormal people, they always quarrel with our family at every turn, and when our family has a little bit of happiness, they will be yin and yang, for example, when I was admitted to university, our family held a thank-you banquet. >>>More

In the construction of the Qinghai-Tibet railway and highway, plateau permafrost has always been the biggest problem plaguing the construction of the project. Since the 60s of the last century, the Chinese Academy of Sciences has cooperated with the Ministry of Railways, the Northwest Branch of the Chinese Academy of Railway Sciences and other units to endure the dangers of plateau operations such as harsh climate, hypoxia and altitude sickness, solve the world's problems such as plateau permafrost and ecological environment, and make a series of major innovative contributions to the smooth opening of the Qinghai-Tibet Railway and the smooth flow of the Qinghai-Tibet Highway. In order to overcome the problem of frozen soil, since 1961, the Chinese Academy of Sciences has organized its own team to carry out permafrost survey and exploration along the Qinghai-Tibet Highway, and established observation stations for long-term observation. >>>More
