“Prospector Base was a cluster of five ten-meter-diameter inflatable domes, arranged in a tight pentagonal formation. Each dome touched two others on either side for mutual support against the fierce spring winds of the southern hemisphere. The void in the center of the pentagon was filled with a smaller dome, seven-and-a-half meters in diameter. The only equipment the central dome contained was the base water recycler unit. The recycler received wastewater from the galley, and from the shower and sink. Dubbed “the hall” by the EPSILON engineers, hatches connected the smaller central dome with each of the larger five domes that surrounded it. Each large dome was accessible to the others only via the hall. The larger dome closest to the landing party’s direction of travel possessed an airlock to the outside atmosphere. Known as the common room, it housed the main base computer, the communications equipment, the primary electrical supply panels, the CO2 scrubber, the oxygen generator and the backup oxygen supply tanks. The oxygen generator electrolyzed water collected from dehumidifiers located in all domes except the greenhouse and from the CO2 scrubber. It released molecular oxygen directly back into the air supply. The hydrogen it generated was directed to the carbon dioxide scrubber. By combining the Sabatier Reaction with the pyrolysis of waste product methane, the only reaction products were water—which was sent back to the oxygen generator—and graphite. The graphite was removed from a small steel reactor vessel once a week and stored in the shop where Dave and Luis intended to test the feasibility of carbon fiber manufacture. Excess heat generated by the water recycler, the oxygen generator, and the CO2 scrubber supplemented the heat output from the base heating system. The dome to the immediate left contained the crew sleeping quarters and a well-provisioned sick bay. The next dome housed the galley, food storage, and exercise equipment. The table in the galley doubled as the base conference table. The fourth large dome served as the greenhouse. It also housed the composting toilet and a shower. The final dome contained the shop, an assay bench, and a small smelter. The smelter was intended to develop proof-of-concept smelting processes for the various rare earth elements collected from the surrounding region. Subsequent Prospector missions would construct and operate a commercial smelter. A second manual airlock was attached to the shop dome to allow direct unloading of ore and loading of ingots for shipment to Earth.”
