Why is the space station called a laboratory built in space?

The space station is a large, manned, long-term man-made satellite that can operate in space for a long time, and is a semi-permanent space base that orbits the earth. The space station is an important part of the entire space system. It can transport people and materials to and from each other, and undertake communication tasks; It can carry out logistical support, repair and maintenance of other spacecraft; It can be used as a launch platform to send new artificial objects into space; It can also use the special environment of space to engage in scientific research, material processing, and complete tasks such as earth monitoring, resource exploration, weather forecasting, and astronomical observation. It can also dock with other spacecraft in space and combine them into a larger orbital complex, creating good conditions for astronauts to work and live in space for a long time.

The space station is very versatile, and given the high vacuum, high purity, microgravity and high position in space, it has significant value in scientific research, national economy and military as an orbital complex of the former Soviet Salyut-7 space station and the Soyuz spacecraft.

Space activities are very valuable, but valuable space activities, especially those with commercial value, can completely rely on non-manned spacecraft, so that in the 80s of the 20th century, when the United States debated whether to build a space station, Reagan's scientific adviser Keworth said: The main reason why people want to build a space station is to send people into space. He also believes that the Soviet Union developed the Salyut space station because of their lack of advanced electronic technology.

At present, the main role of the space station is to accumulate experience for mankind in building large-scale spacecraft and living and working in space for a long time. With the rise of space tourism, the space station will also have more economic value. By building a space station, we are not only accumulating technology for life in the far reaches of space, but also by reaping significant financial rewards, just as no one ever asks why we launch communications satellites.

In addition, the space station is also a good platform for space technology experiments and applications, which can play an important role in biology, materials and other fields.

The space station accepts astronauts in space for experiments, which can make a manned spacecraft a vehicle for transporting only astronauts, thereby simplifying its internal structure and reducing the material required for space flight.

This can not only reduce the difficulty of its engineering design, but also reduce the cost of spaceflight. In addition, the space station can be manned or unmanned during operation, as long as the astronauts start and debug it, it can continue to work as usual, check regularly, and achieve results at that time.

This can shorten the time of astronauts in space, reduce many consumption, and when the space station fails, it can be repaired and replaced in space, extending the life of the spacecraft. Increasing the life of the space can also reduce the cost of spaceflight.

Because the space station can fly for a long time (months or years), it ensures the continuity and depth of space scientific research, which plays an important role in the gradual deepening of research and the improvement of scientific research quality.

Explore the universe, study the changes of living things in outer space, study man-made ecosystems, study the physical and chemical changes of matter under weightless, intense radiation conditions (such as DNA variation).

It can improve China's construction industry, improve China's space technology, improve China's aerospace industry, make the aerospace industry pay better attention, improve the development of the aerospace industry, and improve China's aerospace capability.

It can make China's scientific research develop at a high level, and it will also carry out some scientific experiments, carry out the main equipment, and also be responsible for completing China's space science experiments, which can improve my scientific research technology.

The thermosphere of the atmosphere of the International Space Station.

The atmosphere is usually divided into 5 layers, namely the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The atmosphere at an altitude of 80 km to about 500 km is called thermospheric brigade. The perigee of the ISS is and the apogee is and its altitude range is within the thermosphere.

The space station is also known as the space station and space station. It is a kind of manned spacecraft that operates in low earth orbit for a long time and can be used by many astronauts to visit, work and live for a long time. There are two types of space stations: single-module space stations and multi-module space stations.

A single-module space station can be launched into orbit by a space launch vehicle in a single operation.

The main uses of the space station are: conducting scientific experiments, developing space resources, developing space industry, conducting high-tech experiments, in-orbit services, and space stations. Among them, in-orbit or mu services include maintenance of the main body or other spacecraft on the space station, upgrading of equipment, etc.; Space station refers to the space station that can be used as a transition station, refueling station, transfer station, ** station, etc. for spacecraft.

We take the International Space Station.

ISS) is the largest man-made object in space and the third brightest object in the sky. So much so that many people can see it in the night sky without a telescope. It is 109 meters long and 75 meters wide – about the size of a football field.

It weighs 420 tons, which is comparable to the weight of 280 cars.

The total space of the space station is 932 cubic meters, of which about two-thirds is used for equipment and storage. Only a third of them are "habitable", meaning it can be inhabited by humans. For all of them, where only six astronauts livedSoundIt may be big, but it's actually very narrow.

A small living spaceEach astronaut's bedroom is a small cabin with a sleeping bag tucked in the bulkhead to prevent them from drifting around while sleeping. The cabin also houses their computers, and there is room for a few other personal belongings.

There are also scientific laboratories where the crew can conduct research. With up to 2,400 research investigations conducted in a single expedition, labs can get very crowded. The crew must make room for each other and all their equipment.

Space ManufacturingDid you know that it takes 42 space flights to assemble the main components of a space station? On the outside there are eight solar panels.

Powering the space station. Together, they produce up to 90 kilowatts of electricity – enough to power 13 Australian homes! The space station also allows for the simultaneous connection of six spacecraft.

These spacecraft come from Russia, Japan or the United States of America.

Bring people and supplies. There are currently six crew members on board the ISS.

The view from inside the Earth's space station is spectacular. There is a special observation window called a cupola. It allows one astronaut to view and photograph the Earth's ** at a time.

The station orbits the Earth 16 times every 24 hours. Imagine seeing 16 sunrises and sunsets every 24 hours. What a wonderful sight it would be.

At present, China also has its own space station, and compared to the International Space Station, our space station is also updated.

The space station is still very large, because there is a lot of physical and reverence testing that needs to be done, and there is some other work to be done. The final spatial structure is actually a sealed system, with insulated windows and bright air in the cabin.

It is 109 meters long and about 75 meters wide, about the size of a basketball court, and is divided into equipment and storage space, as well as living space.

The space in the space station is very large, and the internal structure is also very chaotic, and it looks very complicated, because the structure inside is very important.

As large as a football field, it has a very complex internal structure, with both living areas and operating platforms, as well as research equipment.

The internal structure is very good, and the internal structure is also very complex, and it is also a basic structure, so it is very convenient.

Chinese space station.

The impact of the establishment on the world is undoubtedly extremely far-reaching, which is from the movie "Gravity Celebration".

You can get a glimpse of one or two. In the movie "Gravity", the heroine finally returned to Earth by riding the Chinese space station, which was originally a manifestation of the influence of China's space station on the world.

International Space Station.

It should be the most famous space station, and it is also the only space station in space that has been manned for a long time. As a region consisting of 16 countries.

A huge project to participate in, it can be said to be a miracle in the history of mankind. However, at the beginning of the ISS program, China was refused to join by the United States on the grounds that"The space station has a special purpose"。And we really didn't work on the ISS project.

However, the characteristics of us Chinese are that we are more and more courageous, and the participation of the International Space Station is blocked, so we study our own space station. We don't have a personal part of the equation and we don't know how much of it is, but the difficulty of building a space station is conceivable. Different from ordinary spacecraft, the space station is a one-acre space that can be used by humans to stay in space for a long time, which determines that the space station must have a certain volume, need to regularly replenish water, food, oxygen and other items, life support system, bathroom, toilet, etc.

A complete set is much more difficult than a one-off ship.

The space station can provide a long-term microgravity or even weightlessness for human beings, which has a certain role in promoting various human research, and the research of some new materials and new processes relies on the space fast station. In addition, the space station will have an impact on future human exploration of outer space.

The life support and psychology of the time have a great research role. Therefore, in the event of the loss of the space station, much research will be blocked. But the cost of the space station is huge, so the establishment of the Chinese space station will definitely have an impact on the world.

After all, if the International Space Station is retired one day, there will be only one space station left in China.

It can provide the infrastructure for the development of multidisciplinary and serialized air sock research. It can also strengthen the contact and cooperation with the countries of the world, benefit all mankind, and help China enhance its international status.

After the completion of the space laboratory of China's space station, it can better help China's research in the field of space talk, enhance China's political position and voice in the world, and at the same time be of great significance to the space development of the whole world.

Kai dismantles multidisciplinary research, conducts scientific and technological infiltration experiments under sky conditions, improves the ability of space experiments, promotes the progress of science and technology, and explores space.

Summary. The space station can be in weightlessness for a long time. Under these conditions, long-term observation tests can be carried out on the effects on living organisms and how the physicochemical properties of various substances change. On Earth, weightlessness can only be simulated for a short time.

Why do you want to do scientific experiments on the space station Isn't it possible to do it on Earth?

The space station can be held in weightlessness for long periods of time. Under this condition, long-term observation tests can be carried out on the effects of the cave elimination on living organisms, how the physical and chemical properties of various substances change, etc. On Earth, weightlessness can only be simulated for a short time.
