To study this, I was prompted by the article that Canadian scientists have identified 118 km. as the border of space. Come on?
100 km - the official international border between the atmosphere and space - the Karman line.
Karman's Line - “The height was named after the American scientist Theodore von Karman. He was the first to determine that at about this altitude the atmosphere becomes so rarefied that aerodynamic aviation becomes impossible."
DISCHARGED but ATMOSPHERE.
Further more interesting.:) Everyone knows that the ISS has to constantly adjust its orbit height?
For me personally, it was a discovery that this is due to the fact that the ISS is decelerated by the planet's atmosphere, loses speed and descends … Yes, Yes. The ISS is not in space. The ISS is hanging in the atmosphere. The first manned flight into space took place even lower by a hundred kilometers. Why is that? Why not hang the ISS where there is no need to adjust the orbit? The most popular explanation for the network is because it is already normal! She performs her tasks here too! But in truth … There are no technologies on this planet so far that allow humans to transfer radiation from space.
"1000-1100 km is the maximum height of the auroras, the last manifestation of the atmosphere visible from the Earth's surface (but usually well-noticeable auroras occur at altitudes of 90-400 km)."

4000-17000 Van Alenen radiation belts
90-100 thousand kilometers from the Earth's sea level is the upper boundary of the planet's geocorona.
Overall. 100% space is 100,000 km from the planet. ISS at an altitude of 350 km. Well, mankind does not fly into space … It does not fly …
