Sending up a whole rocket/"catcher" for every single bit of space debris you want to deorbit cannot possibly work.<p>What other options are there?
In N. Stephenson's Seveneves, a major plot point was that sufficient falling debris can superheat the atmosphere. Granted, we've orbited a trivial fraction of the Moon's mass, but have we orbited enough material to cause any warming to the atmosphere upon re-entry? Are we many orders of magnitude away?<p>I'm frankly not even sure how to napkin math such a question.
