You can't 'glide down' from orbit. You need to dump your delta-V somewhere. Stop thinking of orbit as though this chunk of metal is suspended from some big balloon out there. _Everything_ in space is moving, 0.0% if it is moving at the right speed and direction to enter the atmosphere and soft land without a lot of external assistance.

Could be autonomous, could be 'tugboats' with human crew, I don't care. Doesn't really matter, as long as the lifting body of refined raw materials has the right weight to surface ratio, and therefore rarely even peaks above 400°C for a short time.
