# 9: The Moons of Jupiter

Nothing much happened until it was time to make our approach to Jupiter, except that a four-year-old kid turned up missing. The kid's parents searched all around and they passed the word from the control room for everybody to keep an eye open but they still couldn't find him.

So we had a chance to try out the Scouts' emergency organization. The ship's officers couldn't search the ship, since there was just the Captain and two watch officers and Mr. Ortega and his assistant chief. Captain Harkness supplied plans to each of the Scoutmasters and we went through that ship like a kid searching his clothes for a half credit. We turned the kid up, all right, in about twenty minutes. Seems the little devil had snuck into the hydroponics room while it was being serviced and had got himself locked in.

While he was in there he had got thirsty and had tried to drink the solutions they raise the plants in—had drunk some, in fact. The result was just about what you would expect. It didn't do him any real harm but, boy, was that place a mess!

I was talking to Dad about it that night over a game. Peggy had a Girl Scout meeting and Molly was off somewhere; we were alone for once. The baby's mother had raised particular Ned, just as if there had really been something wrong—I mean, what can happen in a space ship? The kid couldn't fall overboard.

Dad said her reaction was perfectly natural.

I said, "See, here, George, does it seem to you that some of the emigrants don't have what it takes to be colonists?"

"Mmmm . . . possibly."

I was thinking of Noisy but the ones I mentioned were Mrs. Tarbutton, who gave up and didn't even come along, and that female—Mrs. Grigsby—who got in trouble and had to wash dishes. And another fellow named Saunders who was continually in trouble with the council for trying to live his own life, wild and free, no matter what it did to the rest of us. "George, how did those characters get past the psycho tests?"

George stopped to peg fifteen-four, then said, "Bill, haven't you ever heard of political influence?"

All I said was, "Huh?"

"It's a shocking thought I know, but you are old enough to get used to the world as it is, instead of the way it ought to be. Take a hypothetical case: I don't suppose that a niece of a state councilor would be very likely to fail the psycho tests. Oh, she might fail the first tests, but a review board might find differently—if the councilor really wanted her to pass."

I chewed this over a while. It did not sound like George; he isn't the cynical type. Me, I'm cynical, but George is usually naive. "In that case, George, there is no use in having psycho tests at all, not if people like that can sneak past."

"Contrariwise. The tests are usually honest. As for those who sneak past, it doesn't matter. Old Mother Nature will take care of them in the long run. Survivors survive." He finished dealing and said, "Wait till you see what I'm going to do to you this hand. You haven't a chance."

He always says that. I said, "Anybody who would use public office like that ought to be impeached!"

George said mildly, "Yep. But don't burn out your jets, son; we've got human beings, not angels, to work with."

On the twenty-fourth of August Captain Harkness took spin off and started bringing us in. We decelerated for better than four hours and then went into free fall about six hundred thousand miles out from Jupiter and on the opposite side from where Ganymede was then. Weightlessness still wasn't any fun but this time we were ready and everyone got shots for it who wanted them. I took mine and no nonsense.

Theoretically the Mayflower could have made it in one compound maneuver, ending up at the end of deceleration in a tight circular orbit around Ganymede. Practically it was much better to sneak in easy and avoid any more trouble with meteorites—with the "false rings," that is.

Of course Jupiter doesn't have rings like Saturn, but it does have quite a lot of sky junk traveling around in the same plane as its moons. If there were enough of it, it would show up like Saturn's rings. There isn't that much, but there is enough to make a pilot walk on eggs coming in. This slow approach gave us a fine front seat for a tour of Jupiter and its satellites.

Most of this stuff we were trying to avoid is in the same plane as Jupiter's equator, just the way Saturn's rings are—so Captain Harkness brought us in over the top of Jupiter, right across Jupiter's north pole. That way, we never did get in the danger zone until we had curved down on the other side to reach Ganymede—and by then we were going fairly slow.

But we weren't going slow when we passed over Jupiter's north pole, no indeedy! We were making better than thirty miles a second and we were close in, about thirty thousand miles. It was quite a sight. Jupiter is ninety thousand miles thick; thirty thousand miles is close—too close for comfort.

I got one good look at it for about two minutes from one of the view ports, then had to give up my place to somebody who hadn't had a turn yet and go back to the bunk room and watch through the vision screen. It was an odd sight; you always think of Jupiter with equatorial bands running parallel across it. But now we were looking at it end on and the bands were circles. It looked like a giant archery target, painted in orange and brick red and brown—except that half of it was chewed away. We saw it in half moon, of course.

There was a dark spot right at the pole. They said that was a zone of permanent clear weather and calm and that you could see clear down to the surface there. I looked but I couldn't see anything; it just looked dark.

As we came over the top, Io—that's satellite number one—suddenly came out of eclipse. Io is about as big as the Moon and was about as far away from us at the time as the Moon is from the Earth, so it looked about Moon size. There was just black sky and then there was a dark, blood red disc and in less than five minutes it was brilliant orange, about the color of Jupiter itself. It simply popped up, like magic.

I looked for Barnard's satellite while we were close in, but missed it. It's the little one that is less than one diameter from the surface of Jupiter—so close that it whirls around Jupiter in twelve hours. I was interested in it because I knew that the Jovian observatory was on it and also the base for Project Jove.

I probably didn't miss anything; Barnard's satellite is only about a hundred and fifty miles in diameter. They say a man can come pretty close to jumping right off it. I asked George about it and he said, no, the escape speed was about five hundred feet per second and who had been filling me up with nonsense?

I looked it up later; he was right. Dad is an absolute mine of useless information. He says a fact should be loved for itself alone.

Callisto was behind us; we had passed her on the way in, but not very close. Europa was off to the right of our course nearly ninety degrees; we saw her in half moon. She was more than four hundred thousand miles away and was not as pretty a sight as the Moon is from Earth.

Ganymede was straight ahead, almost, and growing all the time—and here was a funny thing; Callisto was silvery, like the Moon, but not as bright; Io and Europa were bright orange, as bright as Jupiter itself. Ganymede was downright dull!

I asked George about it; he came through, as usual. "Ganymede used to be about as bright as Io and Europa," he told me. "It's the greenhouse effect—the heat trap. Otherwise we wouldn't be able to live on it."

I knew about that, of course; the greenhouse effect is the most important part of the atmosphere project. When the 1985 expedition landed Ganymede had a surface temperature a couple of hundred degrees below zero—that's cold enough to freeze the milk of human kindness! "But look, George," I objected, "sure, I know about the heat trap, but why is it so dark? It looks like the inside of a sack."

"Light is heat; heat is light," he answered. "What's the difference? It's not dark on the ground; it goes in and doesn't come out—and a good thing, too."

I shut up. It was something new to me and I didn't understand it, so I decided to wait and not pound my teeth about it.

Captain Harkness, slowed her down again as we came up to Ganymede and we got in one good meal while she was under drive. I never did get so I could eat at free fall, even with injections. He leveled her off in a tight circular orbit about a thousand miles up from Ganymede. We had arrived—just as soon as we could get somebody to come and get us.

It was on the trip down to Ganymede's surface that I began to suspect that being a colonist wasn't as glamorous and romantic as it had seemed back on Earth. Instead of three ships to carry us all at once, there was just one ship, the Jitterbug, and she would have fitted into one of the Bifrost's compartments. She could carry only ninety of us at a time and that meant a lot of trips.

I was lucky; I had to wait only three days in free fall. But I lost ten pounds.

While I waited, I worked, helping to stow the freight that the Jitterbug brought up each trip. At last it came our turn and we piled into the Jitterbug. She was terrible; she had shelves rather than decks—they weren't four feet apart. The air was stale and she hadn't been halfway cleaned up since the last trip. There weren't individual acceleration couches; there were just pads covering the deck space and we covered the pads, shoulder to shoulder—and foot in your eye, for that matter.

The skipper was a loud-mouthed old female they called "Captain Hattie" and she kept bawling us out and telling us to hurry. She didn't even wait to make sure that we were all strapped down.

Fortunately it didn't take very long. She drove away so hard that for the first time except in tests I blacked out, then we dropped for about twenty minutes; she gunned her again, and we landed with a terrible bump. And Captain Hattie was shouting, "Out you come, you ground hogs! This is it."

The Jitterbug carried oxygen, rather than the helium-oxygen mix of the Mayflower. We had come down at ten pounds pressure; now Captain Hattie spilled the pressure and let it adjust to Ganymede normal, three pounds. Sure, three pounds of oxygen is enough to live on; that's all Earth has—the other twelve pounds are nitrogen. But a sudden drop in pressure like that is enough to make you gasp anyhow. You aren't suffocating but you feel as if you were.

We were miserable by the time we got out and Peggy had a nose bleed. There weren't any elevators; we had to climb down a rope ladder. And it was cold!

It was snowing; the wind was howling around us and shaking the ladder—the smallest lads they had to lower with a line. There was about eight inches of snow on the ground except where the splash of the Jitterbug's jet had melted it. I could hardly see, the wind was whipping the snow into my face so, but a man grabbed me by the shoulder, swung me around, and shouted, "Keep moving! Keep moving! Over that way."

I headed the way he pointed. There was another man at the edge of the blast clearing, singing the same song, and there was a path through the snow, trampled to slush. I could see some other people disappearing in the snow ahead and I took out after them, dogtrotting to keep warm.

It must nave been half a mile to the shelter and cold all the way. We weren't dressed for it. I was chilled through and my feet were soaking wet by the time we got inside.

The shelter was a big hangarlike building and it was not much warmer, the door was open so much, but it was out of the weather and it felt good to be inside. It was jammed with people, some of them in ship suits and some of them Ganymedeans—you couldn't miss the colonial men; they were bearded and some of them wore their hair long as well. I decided that was one style I was not going to copy; I'd be smooth shaven, like George.

I went scouting around, trying to find George & Co. I finally did. He had found a bale of something for Molly to sit on and she was holding Peggy on her lap. Peg's nose had stopped bleeding. I was glad to see, but there were dried tears and blood and dirt on her face. She was a sight.

George was looking gloomy, the way he did the first few days without his pipe. I came up and said, "Hi, folks!"

George looked around and smiled and said, "Well, Bill, fancy meeting you here! How is it going?"

"Now that you ask me," I answered, "it looks like a shambles."

He looked gloomy again and said, "Oh, I suppose they will get things straightened out presently."

We didn't get a chance to discuss it. A colonist with snow on his boots and hair on his face stopped near us, put his little fingers to his lips, and whistled. "Pipe down!" he shouted. "I want twelve able-bodied men and boys for the baggage party." He looked around and started pointing. "You—and you—and you—"

George was the ninth "You"; I was the tenth.

Molly started to protest. I think George might have balked if she had not. Instead he said, "No, Molly, I guess it has to be done. Come on, Bill."

So we went back out into the cold.

There was a tractor truck outside and we were loaded in it standing up, then we lumbered back to the rocket site. Dad saw to it that I was sent up into the Jitterbug to get me out of the weather and I was treated to another dose of Captain Hattie's tongue; we couldn't work fast enough to suit her. But we got our baggage lowered finally; it was in the truck by the time I was down out of the ship. The trip back was cold, too.

Molly and Peggy were not where we had left them. The big room was almost empty and we were told to go on into another building through a connecting door. George was upset, I could see, from finding Molly gone.

In the next building there were big signs with arrows: MEN & BOYS—TO THE RIGHT and WOMEN & GIRLS—TO THE LEFT. George promptly turned to the left. He got about ten yards and was stopped by a stern-faced woman dressed like a colonial, in a coverall. "Back the other way," she said firmly. "This is the way to the ladies' dormitory."

"Yes, I know," agreed Dad, "but I want to find my wife."

"You can look for her at supper."

"I want to see her now."

"I haven't any facilities for seeking out any one person at this time. You'll have to wait."

"But—" There were several women crowding past us and going on inside. Dad spotted one from our deck in the Mayflower. "Mrs. Archibald!"

She turned around. "Oh—Mr. Lermer. How do you do?"

"Mrs. Archibald," Dad said intently, "could you find Molly and let her know that I'm waiting here?"

"Why, I'd be glad to try, Mr. Lermer."

"Thanks, Mrs. Archibald, a thousand thanks!"

"Not at all." She went away and we waited, ignoring the stern-faced guard. Presently Molly showed up without Peggy. You would have thought Dad hadn't seen her for a month.

"I didn't know what to do, dear," she said. "They said we had to come and it seemed better to get Peggy settled down. I knew you would find us."

"Where is Peggy now?"

"I put her to bed."

We went back to the main hall. There was a desk there with a man behind it; over his head was a sign: IMMIGRATION SERVICE—INFORMATION. There was quite a line up at it; we took our place in the queue.

"How is Peggy?" Dad asked.

"I'm afraid she is catching a cold."

"I hope—" Dad said. "Ah, I HOPE—Atchoo!"

"And so are you," Molly said accusingly.

"I don't catch cold," Dad said, wiping his eyes. "That was just a reflex."

"Hmm—" said Molly.

The line up took us past a low balcony. Two boys, my age or older, were leaning on the rail and looking us over. They were colonials and one was trying to grow a beard, but it was pretty crummy.

One turned to the other and said, "Rafe, will you look at what they are sending us these days?"

The other said, "It's sad."

The first one pointed a thumb at me and went on, "Take that one, now—the artistic type, no doubt."

The second one stared at me thoughtfully. "Is it alive?" he asked.

"Does it matter?" the first one answered.

I turned my back on them, whereupon they both laughed. I hate self-panickers.
