Joe was sleeping in air, one hand gripping a bunk rail. He looked perfectly
comfortable.
Now the waking workers were swapping yarns and playing poker for pennies. I
was satisfied just to listen, familiarizing myself with their qualities. These
were generally uneducated folk, illiterate or partially literate, but canny
enough in their limited fashion. Literacy does not equate to intelligence or
humanity, after all. I was not familiar with their game of poker, but figured
I could learn it in due course.
Meanwhile, as a mental exercise, I calculated, in the unfamiliar Jupiter units
of miles, the location of the agricultural bubble we were traveling to. I had
been raised on the superior metric system, but I knew I would have to become
conversant with the system of the Colossus if I wanted to convert my alien
residency to proper citizenship. Also, my lost love Helse had used the Jupiter
system of measurements, so I felt closer to her with them, foolish as this may
seem.
Acceleration measured in this fashion came to 32 feet per second squared, for
one gee. 3,600 seconds in an hour meant-this was pretty good mental exercise,
because of the irregular intervals between units-about 115,000 feet per second
in an hour of gee, which seemed to be what we had experienced. There were-I
strained to remember -5,280 feet in a mile. That meant we were traveling about
22 miles per second now, or close to 80,000 miles per hour. Fifteen hours at
that velocity would be about 1,200,000 miles. But we would not be traveling
straight in toward Jupiter; we would angle back to intercept the bubble as it
overhauled Leda in its smaller, faster orbit. The bubble was probably about
ten million kilometers out from Jupiter, compared to Leda's eleven million-
oops, I had slipped back into the metric system!
At any rate, I was satisfied that the bubble was about 90 percent of Leda's
distance out, in this miniature Solar System that was the Juclip, and that we
would not be carried far from Leda in the ten days Joe said we would be
picking. That reassured me; I didn't want to get lost and not be on hand to
recover my identification.
We did indeed arrive on schedule, decelerating at gee for an hour and docking
on the bubble. Our ship simply hooked onto a rack awaiting it and hung nose-
out, suddenly upside down as the gee resumed. The bunks were made to take it;
they could be used from either side. The bubble was rotating one complete turn
every minute and a half, so that centrifugal force brought our weight at its
surface to almost gee, Earth-normal gravity.
We climbed the ladder-tube up into the bubble. Inside, we stepped out of the
lock onto the great, curving inner surface. I stood, dazzled by it.
The bubble was a virtually hollow sphere about a thousand feet in diameter.
From a mirror in its center shone the sun; or rather, the twenty-sevenfold
magnified image of the sun, projecting the hellish intensity of Earth-normal
solar radiation to the broad, curved expanse of green plants. I knew I would
not be able to tolerate that very long; the radiation would soon blister my
skin.
The bubble was, of course, oriented so that its pole pointed to the sun.
Otherwise the light would have been flashing on and off in sub-two-minute
cycles, not good for the plants. This way, the bubble's rotation was
