Why did the United States build the Skylab space station?

In 2020, the United States will start building a lunar space station? But the purpose is not to explore the moon!

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 main module of the "Skylab" is 15 meters long and has an internal space of more than 300 cubic meters, which is equivalent to a 100-square-meter conference room as a space station.

It's spectacular to have such a big room. The cabin is divided into two floors, the upper floor is the working area, and the lower floor is the living area. On the upper floor, there are laboratory equipment, water tanks, and storerooms, and on the lower floor there are kitchens, bedrooms, washrooms, toilets, bathrooms, and even garbage cans.

There is a grid floor between the work area and the living area, and there is a hole in the floor slab to replace the staircase. Astronauts go up and down the stairs without an elevator or a pin, and if they want to go upstairs, they can fly up with a slight kick and gently push the ceiling with their hands.

He could easily go downstairs, go up and down, and come and go as he pleased.

On May 14, 1973, the United States successfully launched a space station called Skylab, which operated in a near-circular space orbit at an altitude of 435 kilometers, and successively received three groups of nine astronauts from Laozhen to work on the station. They stayed on the station for 28, 59 and 84 days, respectively. With a total length of 36 meters, a maximum diameter of 6 7 meters and a total weight of 77 5 tons, Skylab consists of an orbital module, a transition module and a docking module, providing a workplace of 360 cubic meters.

On May 25, July 28 and November 16, 1973, the Apollo spacecraft sent several groups of astronauts to work on the space station. During the manned flight, the astronauts used 58 kinds of scientific instruments to carry out more than 270 experiments on biomedicine, space physics, astronomical observation, resource exploration and technological technology, photographed a large number of solar activities and the earth's surface, and studied various phenomena of human space activities. After the third group of astronauts left space and returned to Earth in February 1974, Skylab was closed until July 12, 1979, when it crashed into the atmosphere over the southern Indian Ocean and burned up.

It has been in space for 2,249 days and has a range of more than 1.4 billion kilometres.

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 three astronauts, the first owners of the "Skylab", stayed on it for 28 days and 50 minutes, and left the "Skylab" on June 23 and returned safely to the homeland of mankind on the Apollo spacecraft.

Then, on July 28, the second group of astronauts, consisting of Commander Aaron Bean, Orn Galliot and Jacques Rusma, arrived at Skylab on a spacecraft and lived in space for 59 days.

The third group of glorious envoys to "Skylab" were Commander Girardhuzhen Ga, William Pogue and Edwald Gibson, who spent a meaningful 84 days in space from November 16, 1973 to February 8, 1974, and ushered in a new year in space.

On May 14, 1973, the United States successfully launched a space station called Skylab, which operated in a near-circular space orbit at an altitude of 435 kilometers, and received three groups of nine astronauts to work on the station. The nine astronauts arrived on the station to work. The nine astronauts stayed on the station for 28, 59 and 84 days, respectively.

With a total length of 36 meters, a maximum diameter of meters, and a gross weight tonnage, Skylab consists of an orbital module, a transition module, and a docking compartment, providing a workplace of 360 cubic meters. On May 25, July 28 and November 16, 1973, the Apollo spacecraft sent astronauts to work on the space station. During the flight, the astronauts used 58 kinds of scientific instruments to conduct more than 270 biomedical, space physics, astronomical observations, resource exploration and technological blind technology and other experiments, photographed a large number of solar activities and the earth's surface, and studied various phenomena of human space activities.

When the third group of astronauts left space and returned to Earth in February 1974, Skylab was closed and shut down. Skylab USA operates in space for 2,249 days and has a range of more than 1.4 billion kilometers.

Since the space station of the former Soviet Union was launched, it has been working with the Soyuz series of manned spacecraft and the Progress series of cargo spacecraft to form an orbital consortium to carry out space flight missions.
