Is there really someone on the International Space Station all the time?

Yes, the International Space Station has always been manned.

There are always astronauts on the International Space Station. The work plan is divided into short-term scientific experiments and long-term scientific observations. Short-term scientific experiments usually last for weeks or months, while long-term scientific observations usually last for half a year or a year.

There is a separate "room" in the living area of the International Space Station for astronauts to bathe and sleep. There is a kitchen with a refrigerator, a dining table and sports equipment for astronauts to exercise.

Extended data

In the past few years, the International Space Station has really provided a good place for our scientific research. In zero gravity environment (or microgravity environment), researchers can carry out many experiments that cannot be carried out on the ground.

This point, although sometimes manned spacecraft can do it, but the running time of the spacecraft is relatively short, which is not comparable to that of a large space station. The long-term operation of the space station allows astronauts to live and work in it for a long time, and more experiments can be carried out.

In the past ten years, more than 230 researchers from 18 countries have conducted more than 2,400 experiments on the International Space Station. In addition, astronauts have carried out more than 1300 extravehicular activities and 2 17 spacewalks.

The scientific experiments carried out on the space station cover six research fields: physical science, biology and biotechnology, technology development and verification, human research, earth and space science, and educational activities and publicity.
