Turns out, in NMS, if you plonk an automated miner down on a resource deposit, then mine the resource deposit with the terrain manipulator while it's harvesting, you get the resources from the deposit you just slurped up, AND the miner keeps going, just... hovering in the air. I have no idea how long it'll last, but... dang.
