They had been married the day they left. The space ship was so crowded there was no chance for privacy, so the two had no honeymoon till they reached the station. * * * * * Aron and his bride arrived on Kligor in what was autumn on the planet, for the seasons were consistent in all hemispheres. Aron planned to spend a week at the station with his wife and then begin a planetary check of the various automatic observation stations that compiled the meteorological and other data and relayed it by radio to the main station. This check had to be completed before snow came to the planet. In that week they learned about each other. Neither of them was young and both were mature and prosaic enough to develop the daily routine of a long-married couple. There were many free hours which they would spend talking about themselves. To Martha, marriage was not new. She had experienced matrimony before. Her husband, a gambler, had killed himself after a bad loss, leaving her with an impossible burden of debt and a disillusioned mind. Since then she had worked, gradually paying off his debts. When Aron had come along, she liked the big man and thought that the years on Kligor would give her respite from a demanding reality. She did not picture herself as a tragic figure, but rather as merely competent and stable, not realizing that that attitude in itself is a sure sign of instability. A smile seldom found her face. She was slightly nervous with a tendency towards moodiness. Aron's history was not so bitter. He was born in a large family and had formed an aloof, reserved nature to achieve a sense of individuality in the group. His life had been spent in government work and he had never tasted the variable brew of the nuptial cup till he met Martha. He was not a deep man in emotion. His nature was such that he had to be constantly occupied with something--not the frenzied scurrying of insecure individuals--but a solid problem that he could work out. A project that he could carefully shape with a keen analytical mind or capable hands. They did not think of each other in terms of these thumbnail sketches, but merely watched and observed--and adjusted to each other. Their marriage was almost one of convenience, with just enough affection involved to oil over any disputes. The spell of the planet gradually lulled them into hypnotic acceptance of their sequestered lives. Their daily duties became the only things worth thinking about. * * * * * Aron learned about the planet in the next two months on his tours of inspection. He used a small atmosphere flier to cover the various posts scattered over its surface. The small blockhouses were automatic and hermetically sealed to preserve the instruments, but something could go wrong and then it was his job to fix it.
