Yep. That would definitely be something they'd want to own and classify. It might also be forbidden by space demilitarization treaties. After all, if you can shoot down junk, you can shoot down satellites -- including manned ones.<br /><br />The main stumbling block to space junk businesses is that it takes a considerable amount of energy to deorbit each chunk -- and the bigger it is, the more energy it will take. An earth-based system would be plausible with current tech, but you would have to arrange for entries which consume the junk, which means you can't get any money from the salvaged scrap. You'd have to charge somebody for the service of clearing junk, and I don't think anybody's really prepared to pay for that at present. Reclaiming space junk isn't practical, however, because not only will you need spacecraft that can safely reenter with it, but they need to acheive many enormous plane shifts (lots of delta-V) in their operational career, and they need to not contribute just as much junk from their boosters/payload fairings/etc as the stuff they're cleaning up after. It would cost way more than it would make, and is probably dependent on new tech.<br /><br />The laser is probably the most practical at present, to be honest. And even that isn't going to be something done commercially; there's really no return on it. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em> -- The Tenth Doctor, "Blink"</font></p> </div>
