I thought it was also “what about future space exploration in general?” And I don’t think that issue’s actually been dealt with. It’s just being ignored – whether due to current emergency usefulness, or due to a general societal attitude of ‘oh hell let’s go ahead and do it and we’ll clean up the mess afterward, nevermind whether we have any idea how to do that’, I don’t know.
If I’m wrong, and it’s been concluded either that there’s no problem or that there’s a definitely-usable solution, please let me know; though maybe in a different thread.
Thanks.
