Me, too.
Anyway, the ISS is in the buckyball atmosphere - it is not in a vacuum. There is wind up there - howling wind, going at thousands of miles an hour.
It is just very thin.
If (if, mind you) I was in the mind to bite, I would reflect on the fact that the solar wind extends far beyond Pluto, and has enough of a strength to enable solar-sailed spacecraft to be built.
I would also reflect on the fact that enormous electrically charged interstellar gasses are observed stretching across light years in length.
So, if I continued to reflect, I would duly conclude that unless you actually went fully intergalactic, you'd always be in some sort of "wind" (and even then, who knows what flows between galaxies?).
But if I were then to limit my reflections to the ISS, I would probably conclude that minute variations in the earth's gravitational field would be the probable cause of the perturbations and gradual degradation of the ISS orbit, rather than ionic wind at that altitude.
Granted, I could be wrong.
But at this hour of the night, I wouldn't agree to it without being shown a lot of colorful charts to prove it.
