What was the first space station in the world?

The salute 197 1 launched by the former Soviet Union is the first space station in the world.

Due to the continuous progress of society and science, astronomy has developed to this day, and the research objects and methods are constantly expanding, such as the continuous improvement of telescopes and the continuous launch of satellites and various space stations, which have made important contributions to the development of astronomy.

So far, nine narrow stations have been launched around the world. Judging from the launch time. The salute 197 1 launched by the former Soviet Union in April 2000 was the earliest, so it became the first space station in the world. Salute 1 successfully docked with Soyuz in space after launch. "Salute 1" includes three astronauts, who first protected their own lives, but also completed a lot of scientific experiments and lived and worked in the station for 24 days.

In fact, the Soviet Union launched Salute 1 as a scientific base, and astronomers used it to do a lot of astronomical observations and experiments. In fact, "Salute 1" is a manned satellite in a fixed orbit. It can not only serve as an observation and research base, but also provide fuel for other spacecraft or launch satellites and missiles from above. The implementation of the "Salute 1" project not only found a new technical way to explore the establishment of a new type of near-earth orbit space station, but also laid the foundation for the construction of a large space station in the future.

So, how does Salute 1 carry out its research work? Let's first understand its structure. It is an irregular cylinder, which is mainly composed of three parts: the track module, the service module and the docking module. The total length is about12.5m, the maximum diameter is 4m, and the total weight is about18.5t.. It usually runs in an orbit about 200 kilometers above the earth, and the station is equipped with various experimental equipment, photographic equipment and scientific experimental equipment. After docking with Soyuz successfully, a living cabin with a volume of 100 cubic meter was formed, which can accommodate six astronauts. Then "Salute 1" space station ran in space for six months, and successively docked with "Soyuz 10" and "Soyuz 1 1" to form an orbital complex.

Unfortunately, when it docked with Soyuz 1 1 and returned to Earth, the pressure equalizing valve of the return capsule opened prematurely and three astronauts died. But they left us a lot of scientific achievements, which made people remember their contribution to science forever. Later, "Salute 1" unfortunately burned in the atmosphere on June 197 1.

Generally speaking, the launch of "Salute 1" means that manned space flight has entered a new stage of development.
