What is a space station? Be clear

It's like Alibaba**.

The space station refers to a manned spacecraft that can operate for a long time in low-earth orbit and is used by many astronauts for long-term work and life; The space station effectively guarantees the progress of space scientific research, can provide certain convenience for astronauts to live in space, can also reduce the cost of spaceflight, can also shorten the time of astronauts in space, and effectively guarantees the continuity and depth of space work.

It is an artificial satellite put into space by the country, which can orbit the earth and is a semi-permanent base; It is possible to understand the structure adopted, to develop space resources after completing scientific research, and to promote high-tech experiments and development.

The space station is a kind of manned spacecraft that can live and work. The specific role is to allow astronauts to work, to make astronauts live, and to survey any activity on Earth.

The space station, also known as the space station or space station, is a place for astronauts to carry out scientific experiments and live; It is mainly used to carry out some scientific research that requires special conditions, so as to ensure the high efficiency of space scientific research.

Hello, the space station, also known as the space station, is a small experimental scientific research and military activity base operating in the earth's orbit, and is also a large space platform for astronauts to live and work for a long time in a fixed orbit. The space station is a place to welcome astronauts and space supplies, and is a space base that orbits the earth, and is also known as the "space island". Its main tasks are to study man's ability to adapt to the space environment, detect celestial bodies, observe the earth, make new materials and medicines, and conduct biological experiments.

The space station is generally composed of several cylindrical modules, and is the earliest "space pavilion" that can be inhabited, where there are working modules, service modules, docking cabins, and all equipment are installed in the cabin and on the outer surface of the module. After the space station enters orbit, the solar panels and antennas outside the capsule are automatic.

1. Working cabin.

The working cabin is equipped with relevant instruments and equipment for various research and experiments.

2. Service cabin.

The service compartment is equipped with motor engines, attitude control engines, propellants, oxygen cylinders, power supply systems, radio systems, etc.

3. Docking cabin.

It is used to dock manned spacecraft or cargo spacecraft to deliver supplies, etc.

The space station is also known as the space station and the space station. It is a kind of manned spacecraft that operates in low earth orbit for a long time and can be visited by many astronauts for long-term work and life. 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 at one time, while a multi-module space station is assembled by a space launch vehicle that puts each module into orbit in batches and assembles each module in space. There must be all the facilities that people can live on the space station, and the space station does not have the ability to return to Earth.

An astronaut's life on the space station is mainly to use limited resources and get the job done without gravity. It is said that there are more than 100 kinds of food, most of which are packaged in paper bags, plastic bags or metal cans. But these foods are not fresh, and what they need to make on the space station are some convenience foods.

Many of them are compressed foods, so they need to be heated in hot water and swelled before eating. Of course, these foods are hot, because they have to complete a lot of work tasks and ensure their health. Although the food may not be as delicious as it is on earth, the nutritional combination is complete.

In addition to eating, they have to see through, because the water resources in the space station are relatively scarce, so they will not wash clothes in the space stationAnd we can see that the clothes worn in the space are relatively heavy. Usually, underwear is changed every two or three days, and coats may need to be changed once a week. The clothes that are changed will not be washed, some will be brought back to Earth, and some will be thrown away as cosmic garbage.

Of course, their change of clothes at the space station is also hidden, because everyone has their own room.

As mentioned above, the astronauts on the space station have their own roomsThey are also allowed to bring some personal belongings with them, but there is a limit to the capacity. I remember that there was a very cute astronaut on the space station this time, and he **a lot of TV series and**, ready to go to the space station to enjoy, indicating that their entertainment activities are still very rich. Although the room on the space station is relatively small, probably the size of a bathroom on an airplane, the place is enough for them to wash and rest.

Therefore, the living environment on the space station is not as bad as everyone thinks.

Another important part of an astronaut's life on the space station is work. Their work is divided into two parts, one is astronauts, and their main task is to fly manned spacecraft. There are also some scientific and technological personnel, who carry out various space missions, such as placing satellites in orbit, or recovering and repairing satellites from orbit, conducting space physical exploration, space medical research, or space processing experiments, and so on.

Astronauts not only have to live against gravity on the space station and keep themselves healthy, but also complete a variety of space station missions, which is a very dangerous job. Their lives in the space are not only what everyone sees in the camera, but also very colorful.

I don't think life on the space station is as casual as it is on the ground, because it's very constrained, including in a vacuum, especially the food they eat. It's not as delicious as freshly made.

In space, astronauts sleep as much as they want. In the early days of manned spaceflight between the United States and the Soviet Union, the space in the spacecraft was small, and the astronauts could only sleep in their seats. To prevent inadvertently touching the switch, you must sleep with your hands tied to your chest.

The most special thing in space is the sleeping position, when weightless, the body will naturally become arched when completely relaxed, experts believe that sleeping in space, the body is slightly bent into an arch, which is much more comfortable than lying completely straight and flat.

There is certainly no ground at will, and it will be weightless.

1. Conduct scientific experimentsVarious scientific experiments can be carried out by using various laboratories and extravehicular platforms and other facilities on the station.

2. Develop space resources

3. Develop the space industry, using the space resources obtained on the station, the processing of special materials, the production of pharmaceuticals and the production of various new products.

4. Carry out high-tech testsThe special environmental conditions on the station are used to carry out experimental work in various technical fields such as communication, solar energy, space propulsion, and ground remote sensing.

5. On-orbit serviceIt can also carry out service activities such as maintenance of the main body on the station, maintenance of other spacecraft, upgrading of equipment, and construction of large-scale space equipment.

6. Space Station7. Military operationsThey can engage in all kinds of large-scale military activities, including reconnaissance, photography, space weapon launch and testing, command and control, coordination and liaison, and so on.

Features of the space station.

The space station is characterized by its relatively large size, complex structure, long flight time in orbit, and multiple functions.

One of the features of the space station is its economy. For example, all space stations do not have the function of returning to the ground, but accept astronauts in space for experiments, which can make manned spacecraft a tool for transporting only astronauts, thereby simplifying the structure of the space station, reducing the difficulty of its engineering design and reducing 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 shortens the time astronauts spend in space and reduces a lot of consumption. Rolling silver.

When the space station fails, it can be repaired and replaced in space to extend 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.

Whether the space station is stationary or flying, the space station is flying. The space station is in motion, revolving around the Cracked Earth. The space station, also known as the space station and space station, is a manned spacecraft that operates in low-earth orbit for a long time, works for a long time, can be visited by many astronauts, and can live for a long time.

The space station can be divided into a multi-module space station and a single-module space station, and the single-module space station is launched into orbit by a space launch vehicle;

The multi-module space station is made by the Liangmo space launch vehicle to put each module into orbit in batches and assemble each module in space. The space station does not have the ability to return to Earth, but its facilities have the function of human life. At 18:48 on June 17, 2021, astronauts Tang Hongbo, Nie Haisheng and Liu Boming entered the Tianhe core module successively, which also marked the first time that Chinese entered their own space station.
