He glanced around the space below again. There were the oxygen tanks, set up with a timer, one gently hissing away. There also was a small heating unit with a thermostat that evidently kept the temperature in the animal division at a level—and almost certainly was doing the same for the whole section.

Robin grimaced to himself as he worked the padding back into place on the floor. He might manage to be quite comfortable for a while longer—a day or so more. While there's life, there's hope, he said to himself. Better check the parachute question, too, while I'm at it.

He reversed himself in a neatly executed weightless somersault and making what had once been his roof the floor, worked the padding out there. But here he was thwarted, for he found the rounded metal side of the section's nose. If there were a parachute, it obviously occupied its own compartment at the very tip of the rocket's nose.

He looked out the peephole from his upside-down perch, stared musingly at the panoply of the stars. He wondered if he could recognize a planet should one swing across his narrow field of vision, decided that perhaps he might not be able to do so, so vast were the number of stars present. He looked again at Earth, noticing that it had visibly rotated on its axis. That meant that time had passed, a good deal of it. Mentally he tried to calculate just how much. He was looking at the Eastern Hemisphere now, or a corner of it. At least half a day, or maybe a day and a half, or more. How could he tell how long he had been asleep, how long unconscious?

He realized that he was tired, that his body still ached from the painful take-off. He closed his eyes, and without actually wanting to, fell asleep.

His sleeping body swung slowly to and fro in the tiny space, bumping gently from one side to the other. As he slept he dreamed of falling, dreamed of falling over huge endless cliffs, of dropping down strange chasms, of being carried by huge birds and suddenly being dropped.

His subconscious mind would never give up the insistent awareness that his body was falling. It was a certain thing that such would be the dreams of anyone in space flight. The built-in machinery of self-protection identifies a sense of loss of weight with the automatic warning of a fall. Ten thousand thousand generations of climb from primeval arboreal ancestry found the warning valid—no conscious knowledge otherwise would ever shut off this instinctive alarm.

He awoke again with a start and a convulsive grasp for a tree branch. But he shook off the sensation and rubbed his eyes. He took another sip from the water flask, reached into the compartment below and took one of the bananas. The monkeys were still in each other's arms, but now asleep. The rabbits were nosing the corners of their cage as if everything were perfectly normal.

He looked through his peephole and saw the Moon.

It was large, it was vast, it took up most of the view in his range. It looked as close as the Earth had looked before. He looked upon the stupendous moonscape with awe. It was the vision one strains to see through a telescope. He had often paid a dime to look at it through the six-inch telescope at the City Science Museum. This was the same vision, but bigger and clearer, so very, very clear.
