I'm not sure that's relevant to the broader argument I am making. Don't blast waste into space. It carries with it dramatically higher costs - and drastically higher risks. It's completely untenable according to every study and paper on the matter.

Again, selecting a geographic area away from humans and providing sufficient demarcation is dramatically safer than putting it into a rocket and flying it up into orbit over humans. If you disagree, cite a source on its feasibility - and one on the lack of feasibility of deep geological sequestration. Let's not shoot from the hip on this one. I know I haven't found any.
