There is space vacuum, and hard vacuum. Space in the orbit area around Earth is sort of a pisspoor vacuum. There are gases up there, they are just too thin for us, and the paint chips, dust, nuts bolt and other stuff we have left up there makes even a geosynchronous orbit a challenge, right now, to get a package into orbit without an immediate collision. That’s why NASA talks about “launch windows” for orbital traffic. It’s like pulling out onto a busy city street at rush hour, blindfolded, without getting clobbered.
So space is in reality pseudo-vacuum? Now I’ll know it when I see it. JUST KIDDING!
