The human capital of Endurance dwindled. They were always short on food. Arklets were designed to grow their own food supplies in their translucent outer hulls. But Endurance ’s arklets were buried in ice to protect them from the Hard Rain. The ones near the outside got enough sunlight to produce some food, but not enough compared to the mouths that had to be fed. She began her journey well stocked with emergency provisions, which were rationed out on a schedule that assumed a mission length of one year. As it became clear that the journey would go on much longer, the rations were cut back. Endurance also had abundant stockpiles of vitamins, most of which had survived the Break. These were sought after by the people of the Swarm, who had flown the coop without stockpiling enough of them. Trade began to happen between Endurance and the Swarm, but it wasn’t the free market that the Swarmamentalists had once envisioned. Deals were negotiated over the radio and consummated by exchanges between MIVs and arklets, difficult to arrange because of the need to match orbits that had now become very different.
