_Because they were so likable and intelligent

and adaptable--they were vastly dangerous!_

It's difficult, when you're on one of the asteroids, to keep from

tripping, because it's almost impossible to keep your eyes on the

ground. They never got around to putting portholes in spaceships, you

know--unnecessary when you're flying by GB, and psychologically

inadvisable, besides--so an asteroid is about the only place, apart from

Luna, where you can really see the stars.

There are so many stars in an asteroid sky that they look like clouds;

like massive, heaped-up silver clouds floating slowly around the inner

surface of the vast ebony sphere that surrounds you and your tiny

foothold. They are near enough to touch, and you want to touch them, but

they are so frighteningly far away ... and so beautiful: there's nothing

in creation half so beautiful as an asteroid sky.

You don't want to look down, naturally.

I had left the _Lucky Pierre_ to search for fossils (I'm David Koontz,

the _Lucky Pierre_'s paleontologist). Somewhere off in the darkness on

either side of me were Joe Hargraves, gadgeting for mineral deposits,

and Ed Reiss, hopefully on the lookout for anything alive. The _Lucky

Pierre_ was back of us, her body out of sight behind a low black ridge,

only her gleaming nose poking above like a porpoise coming up for air.

When I looked back, I could see, along the jagged rim of the ridge, the

busy reflected flickerings of the bubble-camp the techs were throwing

together. Otherwise all was black, except for our blue-white torch beams

that darted here and there over the gritty, rocky surface.

The twenty-nine of us were E.T.I. Team 17, whose assignment was the

asteroids. We were four years and three months out of Terra, and we'd

reached Vesta right on schedule. Ten minutes after landing, we had known

that the clod was part of the crust of Planet X--or Sorn, to give it its

right name--one of the few such parts that hadn't been blown clean out

of the Solar System.

That made Vesta extra-special. It meant settling down for a while. It

meant a careful, months-long scrutiny of Vesta's every square inch and a

lot of her cubic ones, especially by the life-scientists. Fossils,

artifacts, animate life ... a surface chunk of Sorn might harbor any of

these, or all. Some we'd tackled already had a few.

In a day or so, of course, we'd have the one-man beetles and crewboats

out, and the floodlights orbiting overhead, and Vesta would be as

exposed to us as a molecule on a microscreen. Then work would start in

earnest. But in the meantime--and as usual--Hargraves, Reiss and I were

out prowling, our weighted boots clomping along in darkness. Captain

Feldman had long ago given up trying to keep his science-minded charges

from galloping off alone like this. In spite of being a military man,

Feld's a nice guy; he just shrugs and says, "Scientists!" when we appear

brightly at the airlock, waiting to be let out.

So the three of us went our separate ways, and soon were out of sight of

one another. Ed Reiss, the biologist, was looking hardest for animate

life, naturally.

But I found it.

I had crossed a long, rounded expanse of rock--lava, wonderfully

colored--and was descending into a boulder-cluttered pocket. I was

nearing the "bottom" of the chunk, the part that had been the deepest

beneath Sorn's surface before the blow-up. It was the likeliest place to

look for fossils.

But instead of looking for fossils, my eyes kept rising to those

incredible stars. You get that way particularly after several weeks of

living in steel; and it was lucky that I got that way this time, or I

might have missed the Zen.

My feet tangled with a rock. I started a slow, light-gravity fall, and

looked down to catch my balance. My torch beam flickered across a small,

red-furred teddy-bear shape. The light passed on. I brought it sharply

back to target.

My hair did _not_ stand on end, regardless of what you've heard me

quoted as saying. Why should it have, when I already knew Yurt so

well--considered him, in fact, one of my closest friends?

The Zen was standing by a rock, one paw resting on it, ears cocked

forward, its stubby hind legs braced ready to launch it into flight. Big

yellow eyes blinked unemotionally at the glare of the torch, and I cut

down its brilliance with a twist of the polarizer lens.

The creature stared at me, looking ready to jump halfway to Mars or

straight at me if I made a wrong move.

I addressed it in its own language, clucking my tongue and whistling

through my teeth: "Suh, Zen--"

In the blue-white light of the torch, the Zen shivered. It didn't say

anything. I thought I knew why. Three thousand years of darkness and

silence ...
