The world is on the contrary: what can not be done in space, as well as what is necessary for stability within the ship

The most popular answer to the question of what can not bedoing in space is to hang yourself. Indeed, it will not be possible to break off your life in this way, nor will you do a lot of other things customary to man. The reason for this is the absence of gravity in the cosmos (gravity force). Any objects in space lose their mass and stability in space, known physical laws stop functioning.

Bans and impossibilities in space

Listing what can not be done in space shouldimmediately note - it's about the space inside the ship, not outside it. In the open space, a person can exist only in a spacesuit, and even then not for long. Without protection, the open space kills painfully in 10-12 seconds.

Among the things that can not be done in space, we can distinguish the following:

1. Walk, lean, crouch, fall andto lie down. In space, only one way of controlled movement is available - a leisurely flight. Due to the lack of gravity, objects, living and non-living, lose their mass. The cosmonauts cautiously sort out with their feet (ask direction) and sleep in the air, fastening themselves with straps. What can not be done in space, so it's a sudden movement. It is not recommended even to sneeze, because the sharp output is capable of giving unnecessary acceleration.
2. Get steam (boil water). Because of zero gravity, there is no mixing of the layers. That is, only the liquid layer that is directly contacted with the heating site is heated.
3. Pour out the liquid. Water or any solution in space turns into an independent body that is in its own motion to something (wall, expensive equipment or the person of the nearest cosmonaut). Therefore, all the vessels on the ISS are closed, water is drunk through special tubes, and they go to the toilet through special equipment. Similar rules apply to all kinds of aerosols.

What to do in space

The most important thing that can not be done in space isstop straining the muscles of the body. Weightlessness has a bad effect on the human body, leading to atrophy and the inability to move in conditions of gravity. So cosmonauts should devote every day at least 1 hour to physical exercises. Regular exercises reduce the rate of weight loss, but completely from weakness can not be relieved. Cosmonauts, after returning to Earth, are being rehabilitated.

In addition, there is a mass loss during flightsbones - tissues literally "dissolve" because of the lack of gravity. To support the body and the immune system, astronauts are required to take special complexes of drugs.

The second nuance associated with staying ona space ship, is a sensitive sense of smell. Those who are on the ISS because of the influx of blood into the upper body strongly (by 30% or more) exacerbated perception. It is noted that cosmonauts perceive even the slightest aroma as a sharp stench. Therefore, the organizers of flights ensure that food, supplies and equipment for the space station do not have a smell.

Astronauts themselves should not use scentedsubstances (perfumes, deodorants, fragrant soaps, ointments, etc.) and are required to monitor the level of sweating. Clothing and underwear have gaskets made of antibacterial tissue, and there is a shower for cleaning on the ISS.

Another danger that can killman in space, is associated with a mental state. Guaranteed protection from depression and sudden hysteria does not exist. To reduce mental instability, astronauts must observe the regime - to fall asleep in the cells with the imitation of the night (darkening) or with a mask for sleep, to regularly take water and food (600 grams per day), and alternate their work and playing sports.

In general, space is defined as an aggressive environment,much more dangerous than the highlands or the desert. Evolutionarily man is not adapted for existence outside the Earth, and for those in space the probability of death (including sudden) increases tenfold.
