Flying astronaut in the world's largest swimming pool

Hundreds of astronauts will be trained and trained to get used to the weightless condition of flying into space.

Many large devices in the swimming pool are all familiar in space, helping astronauts not to be surprised when living on the International Space Station (ISS).

Astronauts will practice the most difficult exercises, because they may have to encounter situations in more complex conditions when entering space.

Regular practice at the swimming pool helps astronauts out of the earth's atmosphere to avoid illness, nausea or dizziness.

Training participants will have to wear astronaut clothes. NASA's swimming pool is also the training ground for astronaut Chris Hadfield, who began to fame over the past few months with a series of YouTube videos about his own experiences in space.

Astronauts will have to work hard, precisely in the lab movements, to find the missing points and practice carefully, avoiding mistakes when working outside the earth.

All astronauts' underwater practice is recorded by the camera system. Experts at the operating room will follow the screen directly.
