Which is precisely what I meant... the fact that it's polluted by solid debris rather than chemical effluent doesn't make it less dangerous, given the specificities of that environment and human interaction with it.Schneibster wrote:There is that, but it's not what I meant.Svartalf wrote:If you solely mean chemical/radiological pollution, indeed it doesn't, especially since anything outside the atmosphere gets irradiated to degrees we can hardly imagine.
When they talk about "pollution," what they mean is dropped tools or nuts and bolts or other fragments of old spacecraft, or even whole old spacecraft, in retrograde or eccentric orbits, that pose an impact hazard to missions. And that's only in low Earth orbit; the risk further up is less than that from asteroid or comet material.
I was actually invoking a meme you may not be familiar with: "pollute space" is one of the more amusingly totally wrong ideas I've seen anti-technology idiots deploy.
But I have no idea what meme you were invoking.
