What can not be done in outer space? About an unusual life outside terrestrial conditions

The usual life of astronauts hides in itself a lot of surprising. Far outer space is completely different from the life that people are used to. What differences exist between life in the comfortable conditions of the Earth and the surrounding cosmos?

The first thing to do is put on a space suit

The first thing that can not be done in space is to be there without a special spacesuit. A man will not survive and a couple of minutes in an open airless space. Since there is no external pressure, then any living organism expects an unenviable fate: the bubbles of gas inside will begin to disperse evenly, with the lungs bursting, and then the mucous membranes of the eyes and mouth begin to boil.

What can not be done in outer space? The exact time and its deceleration

Even in space it is impossible to know the exact time. All this happens according to the principles of the theory of relativity of Einstein. But do not get scared - not everything is so complicated. Just on Earth, time flows for a few seconds faster than on the ISS. This is due to the fact that in the near-Earth orbit the gravitational force is very small (its complete absence is possible only in distant cosmic spaces, where there are no celestial bodies nearby). The speed of the ISS reaches incredible values - about 7.9 km / s. And according to the theory of relativity, the lack of gravity and high speed change the flow of time. But all this passes relatively without consequences - if, for example, the cosmonaut spent several months on the ISS. If there is a distant interstellar journey, then, returning home, he is unlikely to find even his great-grandchildren.

How do the stars look if you look at them without the atmosphere?

What can not be done in space from what on Earth seems familiar and ordinary? In the open space, such pleasure becomes inaccessible, as to look at the stars. After all, from the surface of the globe, a person sees them flickering through a dense veil of atmosphere. People look at the stars in much the same way as through the water column. Therefore, in space, the stars shine with all their might.

Simple things: boil the kettle, write with a pen

To write with a ballpoint pen is another lesson that can not be done in space. The answer to this problem was previously of interest to many schoolchildren, especially during the Soviet era. Why is this happening, and what do you have to write to cosmonauts then? The fact is that in space there is no gravity. It is necessary for a conventional pen so that the ink gradually approaches its base, and the letter becomes possible. In Soviet times, cosmonauts wrote with pencils made of wax. After all, graphite rods could break off, and their particles become a threat to the breathing of astronauts. Cosmonauts from the United States used felt pens.

And also in space it is impossible to make one more simple action - to boil a teapot. This is due to the physics of open space. From the school course, everyone remembers that the higher you go, the lower the boiling point of water. For example, at the top of the mountain the kettle will boil faster than the bottom, at the foot. And in space, with complete absence of pressure, water will boil almost instantly.

True, the vapor particles will immediately turn into ice crystals, because in space it is very cold. On interplanetary space stations, water is still subjected to boiling. After all, inside of them, though artificially, pressure and temperature are created. At the ISS, something that can not be done in space is being done - the water in the kettle is boiling. But this happens at a temperature of 85 ° C.

Is it possible to use perfume in space?

This is another case from the list, which is impossible in the near-planetary space. It is possible to suffocate, of course, but the smell will be too sharp. In general, everything that concerns smells and flavors in space has its own characteristics. For example, food always seems unsalted. Therefore, cosmonauts are provided with a lot of seasonings. The cosmonauts themselves say that the cosmos has the smell of roasted steak. And the smell of the moon is like the smell of pea burning.

Game for the development of thinking

In many logical games and quizzes, a question is asked about what can not be done in outer space. The game "Matryoshka" in "Odnoklassniki" is one of the examples of such games. On the Internet, of course, there are a lot of such games. However, this game is different in the variety of tasks and topics. Every day new members join it. One of the most entertaining questions in this game is "What can not be done in outer space?". "Matryoshka" gaining popularity due to the fact that they can significantly expand the horizon.
