In the not too distant future, perhaps as early as the next decade, an international conference on space flight will be convened. It will differ from all other similar conferences in that the majority of its delegates will be lawyers from different countries. The main problem of this conference will be the question of the boundary separating outer space from the earth's atmosphere. It is highly probable that a height of 250 km will be chosen as this boundary.

The legalized boundary of outer space is necessary, since representatives of various sciences still cannot come to a consensus on this issue. The minimum value of the height where outer space begins is proposed by doctors. The Department of Astromedicine has adopted a special term for this height - "space-equivalent height". In numerical terms, it is about 18,000 m. The reason for choosing such a relatively small value, according to physicians, is this: for most people, staying at an altitude of the first 3,000 m does not require any special precautions. Moreover, for them, the altitude can be freely increased to 4500 m. But some people begin to experience symptoms of so-called mountain sickness already at an altitude of 3000 m. Therefore, the US Air Force uses additional oxygen to breathe at an altitude of 2400 m and above. This ensures greater safety for the flight crew.

At an altitude of 7600 m, a person can still breathe, provided that he is sufficiently trained and accustomed to low pressure, and that the pressure decreases gradually. A person who suddenly finds himself in conditions corresponding to an altitude of 7600 m above sea level loses consciousness after 3-4 minutes (this period of time is called the “time of useful consciousness”), during which he can consciously perform some actions. With an increase in altitude by another 1500 m, the “time of useful consciousness” is reduced to one minute. At an altitude of 15,000 m, it fluctuates between 10 and 18 seconds, depending on pre-training and experience. Further, at these heights, another factor, perhaps no less serious, joins the factor of loss of consciousness. It is known that, being raised to a high mountain, water boils at a lower temperature; Generally speaking, the boiling point of any liquid falls as atmospheric pressure decreases. At an altitude of about 18,000 m, this pressure decreases so that the liquid contained in the human body (blood, lymph, etc.) begins to boil at a temperature of 36.6 ° C. Death comes in a few minutes. It is generally accepted that since a person at an altitude of 18,000 m will die for the same reason and in the same period of time as at a distance of 180,000 km from the Earth, insofar as a height of 18,000 m is, from a medical point of view, “spatial - equivalent height.
