The Galileo leaped forward, pressing them back into their pads.
They were headed skyward, out and far.
Chapter 9 - INTO THE LONELY DEPTHS
TO ROSS AND ART THE WORLD seemed to rotate dizzily through ninety degrees. They had been standing up, strapped to their upright hammocks, and staring straight forward past Cargraves and Morrie out through the conning port at the moon and the western horizon.
When the rocket took off it was as if they had been suddenly forced backwards, flat on their backs and pushed heavily into the cushions and springs. Which, in a way, was exactly what had happened to them. It was the powerful thrust of the jet which had forced them back against the springs and held them there. The force of the drive made the direction they were traveling "up."
But the moon still stared back at them, dead ahead through the port; "up" was also "west." From where they lay, flat on their backs, Cargraves and Morrie were above them and were kept from falling on them by the heavy steel thrust members which supported the piloting chairs.
The moon shimmered and boiled under the compression waves of air. The scream of the frantic molecules of air against the skin of the craft was louder and even more nerve-racking than steady thunder of the jet below them. The horizon dropped steadily away from the disk of the moon as they shot west and gained altitude. The sky, early morning gray as they took off, turned noonday blue as their flat climb took them higher and higher into the sunlight.
The sky started to turn purple and the stars came out. The scream of the air was less troublesome. Cargraves cut in his gyros and let Joe the Robot correct his initial course; the moon swung gently to the right about half its width and steadied. "Everybody all right?," he called out, his attention free of the controls for a moment.
"Swell!" Art called back.
"Somebody's sitting on my chest," Ross added.
"What's that?"
"I say, somebody's sitting on my chest!" Ross shouted.
"Well, wait a bit. His brother will be along in a minute."
"What did you say?"
"Never mind!" Cargraves shouted. "It wasn't important. Copilot!"
"Yes, Captain!"
"I'm going into full automatic. Get ready to check our course."
"Aye, aye, sir." Morrie clamped his octant near his face and shifted his head a little so that he could see the scope of the belly radar easily. He dug his head into the pads and braced his arms and hands; he knew what was coming. "Astrogator ready!"
The sky was black now and the stars were sharp. The image of the moon had ceased to shake and the unearthly scream of the air had died away, leaving only the tireless thunder of the jet. They were above the atmosphere, high above—free.
Cargraves yelled, "Hang on to your hats, boys! Here we go! He turned full control over to Joe the Robot pilot. That mindless, mechanical-and-electronic worthy figuratively shook his non-existent head and decided he did not like the course. The image of the moon swung "down" and toward the bow, in terms of the ordinary directions in the ship, until the rocket was headed in a direction nearly forty degrees further east than was the image of the moon.
Having turned the ship to head for the point where the moon would be when the Galileo met it, rather than headed for where it now was, Joe turned his attention to the jet. Thee cadmium plates were withdrawn a little farther; the rocket really bit in and began to dig.
Ross found that there was indeed a whole family on his chest. Breathing was hard work and his eyes seemed foggy.
If Joe had had feelings he need have felt no pride in what he had just done, for his decisions had all been made for him before the ship left the ground. Morrie had selected, with Cargraves' approval, one of several three-dimensional cams and had installed it in Joe's innards. The cam "told" Joe what sort of a course to follow to the moon, what course to head first, how fast to gun the rocket and how long to keep it up. Joe could not see the moon- Joe had never heard of the moon -but his electronic senses could perceive how the ship was headed in relation to the steady, unswerving spin of the gyros and then head the ship in the direction called for by the cam in his tummy.
The cam itself had been designed by a remote cousin of Joe's, the gteat "Eniac" computer at the University of Pennsylvania. By means of the small astrogation computer in the ship either Morrie or Cargraves could work out any necessary problem and control the Galileo by hand, but Joe, with the aid of his cousin, could do the same thing better, faster, more accurately and with unsleeping care—provided the human pilot knew what to ask of him and how to ask it.
Joe had not been invented by Cargraves; thousands of scientists, engineers, and mathematicians had contributed to his existence. His grandfathers had guided the Nazi V-2 rockets in the horror-haunted last days of World War II. His fathers had been developed for the deadly, ocean-spanning guidedmissiles of the UN world police force. His brothers and sisters were found in every rocket ship, private and commercial, passenger-carrying or unmanned, that cleft the skies of earth.
Trans-Atlantic hop or trip to the moon, it was all one to Joe. He did what his cam told him to do. He did not care, he did not even know.
Cargrave called out, "How you making out down there?"
"All right, I guess," Ross answered, his voice laboring painfully.
"I feel sick," Art admitted with a groan.
"Breathe through your mouth. Take deep breaths."
"I can't."
"Well, hang on. It won't be long."
In fact it was only fifty-five seconds at full drive until Joe, still advised by his cam, decided that they had had enough of full drive. The cadmium plates slid farther back into the power pile, thwarting the neutrons; the roar of the rocket drive lessened.
The ship did not slow down; it simply ceased to accelerate so rapidly. It maintained all the speed it had gained and the frictionless vacuum of space did nothing to slow its headlong plunge. But the acceleration was reduced to one earth-surface gravity, one g, enough to overcome the powerful tug of the earth's mighty weight and thereby permit the ship to speed ahead unchecked—a little less than one g, in fact, as the grasp of the earth was already loosening and would continue to drop off to the change-over, more than 200,000 miles out in space, where the attraction of the moon and that of the earth are equal.
For the four in the ship the reduction in the force of the jet had returned them to a trifle less than normal weight, under an artificial gravity produced by the drive of the jet.
This false "gravity" had nothing to do with the pull of the earth; the attraction of the earth can be felt only when one is anchored to it and supported by it, its oceans, or it's air.
The attraction of the earth exists out in space but the human body has no senses which can perceive it. If a man were to fall from a tremendous height, say fifty thousand miles, it would not seem to him that he was falling but rather that the earth was rushing up to meet him.
After the tremendous initial drive had eased off, Cargraves called out again to Art. "Feeling any better, kid?"
"I'm all right now," Art replied.
"Fine. Want to come up here where you can see better?"
"Sure!" responded both Art and Ross, with one voice.
"Okay. Watch your step."
"We will." The two unstrapped themselves and climbed up to the control station by means of hand and toe holds welded to the sides of the ship. Once there they squatted on the supporting beams for the pilots' chairs, one on each side. They looked out.
The moon had not been visible to them from their hammock positions after the change in course. From their new positions they could see it, near the "lower" edge of the conning port. It was full, silver white and so dazzling bright that it hurt their eyes, although not sufficiently nearer to produce any apparent increase in size. The stars around it in the coalblack sky were hard bright diamonds, untwinkling.
