The world is the opposite: what can not be done in space, and also what is necessary for stability within the ship

The most popular answer to the question of what can not be done in outer space is hang yourself. Indeed, it will not be possible to break off your life in this way, nor will you do many other things that are familiar 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

Enumerating what can not be done in space, it should immediately be noted - it is about the space inside the ship, and not beyond 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 and lie. In space, only one way of controlled movement is available - a leisurely flight. Because of 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 sharp move. It is not recommended even to sneeze, because the sharp output is capable of giving unnecessary acceleration.
2. Get the 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, which 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 you need to do in space

The most important thing that can not be done in space is to stop 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 do not save. Astronauts, after returning to Earth, are rehabilitated.

In addition, during flights there is a loss of bone mass - the 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 being on a spaceship 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 fragrance as a sharp stink. Therefore, the organizers of flights ensure that food, supplies and equipment for the space station do not smell.

The cosmonauts themselves should not use odoriferous substances (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 destroy a person in space is connected with the mental state. Guaranteed protection from depression and sudden hysteria does not exist. To reduce mental instability, astronauts are required to comply with the regime - get enough sleep in the cells with imitation of the night (darkening) or with a mask for sleep, 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 tens of times.
