He had disconnected the cable leading from his helmet to the ship’s transmitter and switched on the ship’s fast-lens movie camera that would photograph the area covered by “Harry.” Then he was ready to go outside. He pressed a button on the wall, and the first air-lock hatch opened. He floated into the narrow alcove and closed the door in the cramped chamber behind him. He watched a gauge, and when it showed normal pressure and temperature again, he opened the outside hatch, closing it behind him. Had Marsh permitted the vacuum of space to contact the interior of the ship’s quarters, delicate instruments would have been ruined by the sudden decompression and loss of heat. Marsh fastened his safety line to the ship so that there was no chance of his becoming separated from it. Then he looked “downward,” to experience the thrill of his life. Like a gigantic relief map, the panorama of Earth stretched across his vision. A downy blanket of gray atmosphere spread over the whole of it, and patches of clouds were seen floating like phantom shapes beneath the clear vastness of the stratosphere. It was a stunning sight for Marsh, seeing the pinpoint lights of the night cities extending from horizon to horizon. It gave him an exhilarating feeling of being a king over it all. Earth appeared to be rotating, but Marsh knew it was largely his own and the rocket’s fast speed that was responsible for the illusion. As he hung in this region of the exosphere, he was thankful for his cadet training in zero gravity. A special machine, developed only in recent years, simulated the weightlessness of space and trained the cadets for endurance in such artificial conditions. “Describe some of the things you see, Marshall,” General Forsythe said over Marsh’s helmet receiver. “I’ve just cut in a recorder.” “It’s a scene almost beyond description, sir,” Marsh said into the helmet mike. “The sky is thickly powdered with stars. The Milky Way is very distinct, and I can make out lots of fuzzy spots that must be star clusters and nebulae and comets. Mars is like an extremely bright taillight, and the moon is so strong it hurts my eyes as much as the direct sun does on earth.” Marsh saw a faintly luminous blur pass beyond the ship. It had been almost too sudden to catch. He believed it to be a meteor diving Earthward at a speed around forty-five miles a second. He reported this to the general. As he brought his eyes down from the more distant fixtures of space to those closer by on Earth, a strange thing happened. He was suddenly seized with a fear of falling, although his zero-gravity training had been intended to prepare him against this very thing. A cold sweat come out over his body, and an uncontrollable panic threatened to take hold of him.
