pressure in space. Is the ISS present at the flight altitude?

Question

Physics

Physics probably taught me poorly, but I’m somehow convinced that it should still be present at 400 km, or rather below one atmosphere, but closer not to the physical vacuum, but to the technical vacuum obtained on earth, or rather not even to it, but to a strong rarefaction, because in fact the ISS hangs in the thermosphere, is it likely that there are oxygen molecules there?

Answer 2

There is some non-zero pressure anywhere - even in interstellar space (in the middle between the Sun and Alpha Centauri), and in intergalactic space. And I would not say that it is quite small there - because it is precisely the stars and planets that "suck out / devour" a significant part of the matter during their movement.
Plus, some pressure creates relic radiation.
It seems to me that you are not thinking about what you are asking about. Reframe the question.

Answer 3

And there is only one question, how much pressure in space? How much pressure in the suit? Decide
