I could see most of my drones on the hopper’s feed, a bright dot forming on the three dimensions of the map. Group One was doing what I’d told them, gathering at a rendezvous point near the habitat. I had a calculation going, estimating the bogie’s time of arrival. Right before we passed out of range I told the drones to head northeast. Within moments, they dropped out of my range. They would follow their last instruction until they used up their power cells.
