Space Created On Earth

When cosmonauts work in space they work in a weightless environment. It goes without saying that they need to be prepared for such work. But how can it be done on Earth? It's not as hard as it first seems. Conditions closest to weightlessness are provided by ordinary water. That is why in 1980 they built a water immersion facility in the Cosmonauts Training Center named after Yuri Gagarin. For the thirty years of its existence cosmonauts have spent over 65 000 training hours here, those who have subsequently walked in real space had the same opinion: it felt 95% the same.

The water immersion facility is a complex hydrotechnical construction with a system of technological equipment, special instruments and mechanisms. It is mainly occupied by a huge reservoir: twenty three meters in diameter, about twelve meters deep. The reservoir is filled with water of unique composition whose temperature is about 30 C.

Inside the pool is a motion platform with a lifting capacity of forty tons. Interesting equipment models are secured on the platform: the Russian segment of the ISS, the space ship "Soyuz TMA", etc.  During immersion cosmonauts use special diving suits connected to an external air source. Their work is hazardous, so they are always accompanied by scuba divers while they are under the water.

In fact this water is almost distilled, there is no water with such a low density anywhere else. Powerful spotlights surround the pool from outside contributing to the feeling that you are in real space.

45 portholes along the perimeter of the pool are used for shooting and monitoring during the cosmonauts' training. All of the facility is permanent, its iron is identical to real one - to every single nut and every millimeter.
