context: [Transcriber's Note: This etext was produced from Galaxy Science Fiction November 1951. Rootless and footloose, a man in space can't help but dream of coming home. Flight Officer Robert Craig surrendered the tube containing his service record tapes and stood waiting while the bored process clerk examined the seal. "No specific destination," supplied the man as he punched a key on a small instrument, "Air-lock ahead and to your right. "No, but my father—" "Your parents left Terra during the Second Colonization of Cassiopeia II, didn't they?" "Oh, I've landed a few times, even walked around for a while...." Short of Gravitational conditioning, there is nothing to stop you from going to Terra." Your body is conditioned to a normal state of free fall, or at best to a state of acceleration." It helps suppress certain physiological reactions to an entirely new set of conditions. They play an important part in our awareness of balance. Without gravity they act up for a time, then gradually lose function. Returning to gravity is rather frightening at first." And yet the man could not be pinned down to any specific condition the spaceman would find intolerable. He had been on Einstein IV, the planet of eight moons, and had felt the pulse of all eight of the satellites at once that no PON could completely nullify. But even if he could accept the psychologist's authority for the cumulative effect of a gravity system, he could not understand the unspoken warning he felt underlying all that the man said. On the eighth day, two attendants, who showed the effects of massive doses of PON to protect themselves from the centrifugal force, had to carry a man out of the tank. Many others asked to be removed, begged to be allowed to withdraw their resignations. "The twelfth day is the worst," a grizzled spaceman told Craig. "How ... how do they know when you ought ... to come out?" "Can't they ... drop it down continuously?"
