>...Alternatively, if you have lots of these tiny asteroids in orbit (like
we don't have enough space junk in orbit already!) you could have a robot
shuttle type vehicle which could go up and wander around scooping up these
asteroids and filling up the hold, before re-entry.
A similar type of robot vehicle has already been proposed for cleaning up
space junk in earth orbit.  BillK

BillK, when you make these kinds of suggestions, estimate the delta V
required to do it.  Once you do those calculations a few times, you see why
we don't have some kind of robot shuttle wandering around scooping up space
debris, and why we will not be getting that capability any time soon.
