He'd been a Survey Candidate on Khali II and Taret and Arepo I, all of which were tropical, and a Junior Officer on Menes III and Thotmes--one a semi-arid planet and the other temperate-volcanic--and he'd done an assistant job on Saril's solitary world, which was nine-tenths water. But this first independent survey on his own was another matter. Everything was wholly unfamiliar. An ice-planet with a minus point one habitability rating was upsetting in its peculiarities. He knew what the books said about glacial-world conditions, but that was all. The denseness of the fog his breath made seemed to grow less as the room-warmer whirred and whirred. When by the thinness of the mist he guessed the temperature to be not much under freezing, he climbed out of his bunk and went to the port to look out. His cabin, of course, was in one of the drone-hulls that had brought the colony's equipment to Lani III. The other emptied hulls were precisely ranged in order outside. They were connected by tubular galleries, and painstakingly leveled. They gave an impression of impassioned tidiness among the upheaved, ice-coated mountains all about. He gazed down the long valley in which the colony lay. There were monstrous slanting peaks on either side that partly framed the morning sun. Their flanks were ice. The sky was pale, and the sun had four sun-dogs geometrically about it. Normal post-midnight temperatures in this valley ranged around ten below zero--and this was technically summer. But it was colder than ten below zero now. At noon there were normally tiny trickling rills of surface-thaw running down the sunlit sides of the mountains, but they froze again at night. And this was a sheltered valley, warmer than most of the planet's surface. The sun had its sun-dogs every day, on rising. There were nights when the brighter planets had star-pups, too. The phone-plate lighted and dimmed and lighted and dimmed. They did themselves well on Lani III; the parent world was in this same solar system, making supply easy. That was rare. Bordman stood before the plate and it cleared. Herndon's face peered unhappily out of it. He was even younger than Bordman, and inclined to lean on the supposedly vast experience of a Senior Officer of the Colonial Survey. "Well?" said Bordman, feeling undignified in his sleeping garments. "We're picking up a beam from home," said Herndon anxiously. "But we can't make it out."
