On her flight to Mars, space had been at a premium, but that was nothing compared to her current surroundings. The beds were small plastic boxes contoured for easy stacking. One wall of boxes was open, allowing access to a sparse interior which held nothing but a compressed foam mattress, screen, and water nozzle. The beds rose above and across from each other in towering columns that filled the tall space, the only breaks narrow zigzagging alleyways that stretched up to the dull ceiling. Duct tape held thin aluminum ladders in place while power cables crossed the gap.
