Part 4 (1/2)

No time lag was noticeable. They were only some 15,000 kilometers away. Kivi had identified the body among the data pouring in from the continuous automatic sky-scan and, retrieving earlier information, computed an orbit. Now they saw a rough gray lump, about three kilometers long and one at maximum thickness, slowly tumbling.

”Apparently chondritic,” commented Raden. ”You'll notice the remarkable sparsity of craters. You're right, Maria, it must be from the outer belt, lately perturbed into an eccentric path.

Pristine, Tyra knew, formed hardly more than a billion years ago, in a thinly bestrewn region where there had been scant occasion or time for collisions. Probes were to examine such rocks later. But who knew how much later? Composition and structure might well give unique insights into the early life of every planetary system. This chance was too good to pa.s.s up. Should k.u.mukahi make sudden call on Henrietta Henrietta, she could boost back to Freuchen Freuchen in well under an hour. in well under an hour.

”Backing down on it, essentially,” continued Raden's voice. The asteroid swelled fast in sight. ”As you recall, we'll run parallel and let Jens stare while we send minisamplers-”

The thing erupted. A white cloud burst raggedly forth. Gravel and boulders sleeted outward.

Tyra heard herself scream.

The view swung wildly. The barrage became glints across a whirl of stars. Somebody in the boat yelled, ”Almachtige Gott!” Somebody else ripped an oath.

The view returned to the cabin and steadied on Rader. Sweat studded his brow, but he grinned, well-nigh laughed. ”Whoop, that was close! Thank Josef here. The autopilot isn't programmed for- He yanked us free. Barely, but he did it.”

Brandt looked around, his own expression grim. ”Barely is correct,” he grated. ”Some of those stones could have holed us, or even been bouncers.”

Tyra shuddered. She knew what he meant. The boat lacked a protective screen-field. The hull was self-sealing. But a small object that punched through could lose too much energy thereby to make an exit, not too much to ricochet back and forth and quite likely hit a man.

”Was fur den Teufel-what happened?” roared Worning.

Lillebro spoke almost calmly. ”I can guess. The chondrules surrounded a mixture of ices, which also mortared them together. The agglomerate was metastable, and the impulses from our polarizer drive as we neared touched off volatilization and-it will be fascinating to learn what reactions.”

”A bomb,” added Raden. ”I daresay they're not uncommon in young systems, but all of them are disrupted-solar input, impact energy, perhaps c.u.mulative cosmic ray effects-long before intelligence evolves locally to notice them. What a discovery!”

”It has just begun,” said Lillebro with rising excitement. ”The gas spectrum, and we'll collect specimens-”

”No,” decreed Worning. ”You will return here. At once.”

”What? But, sir, now that we're aware-”

”Of what are we still unaware? I will not risk one of our two boats and three of our lives for something that robots can examine at leisure. Return. That is an order.”

”Yes, sir.” Brandt did not sound unwilling. Lillebro sighed. Raden gave a wry grin and a rueful shrug.

When he cycled aboard, Tyra was waiting at the lock. She reached for his hands. ”You might have been killed,” she stammered, and could not altogether hold back the tears. ”You might have been killed.”

He drew her to him. ”Do you care that much?” he whispered. ”I dared not hope.”

A bunk could be folded out to double width, though it then filled most of the deck s.p.a.ce in a so-called stateroom. Lights could be turned down to softness. Music could be commanded, La c daremm' la mano La c daremm' la mano, Liebestod Liebestod, afterward the lilt and gentleness of Fynsk Foraar Fynsk Foraar, though likewise softened to a background.

”That was amazing,” he said as low. ”I didn't quite expect a supernova.”

”Thank you,” she answered, snuggling, refusing to wonder if he'd used those words before or how often. ”Same order of magnitude to you, sir. But let's settle for ordinary novas. They can repeat.”

He chuckled. His lips brushed her cheek. ”Shameless hussy.”

”I'd better be. You too. How many bets will be paid off tomorrow?”

He looked away. She heard the sudden seriousness. ”You told me you . . . don't do casual.”

She confronted her own spirit. ”I don't.”

”It's far too early to make promises. On either side.”

”I realize that. But I decided, nothing ventured, nothing gained.” And, if this didn't last-certainly the obstacles were many-she would at least have a profit of memories. As he would; she'd see to that. And she had the strength to pay the price. Which maybe wouldn't be required of her.

His eyes met hers. ”I'm being as honest as I'm able,” he said, ”because in fact I am in love with you.”

”All right, it's mutual.”

”I wish I could, well, give you more. Now, I mean, before we go . . . home. We have so little here.”

Through the eased-off happiness she felt her mind sharpen. She had given thought to this too. She did not believe the idea had snapped the leash she kept on herself. His escape did that. Nor was it a price she set, a bargain she struck.

Nevertheless- ”You can,” she said.

His head lifted off the pillow. ”What?”

She moved slightly aside from his warmth and male odor to lean on an elbow and keep hold of his gaze. ”When k.u.mukahi begins breaking up, you'll be out there to watch, won't you?”

”Of course. We haven't that many free machines, and we don't know enough to write adequate programs for any. Who can tell what human observers might catch?”

”Take me along.”

”Eh?” he exclaimed, and sat straight. After a moment, he leaned back. ”No, really, darling, it's not feasible. If the event begins in the next few days, and it probably will, Birgit won't yet be fit to pilot. That leaves Josef for one boat, crammed with scientists and their gear.”

Tyra nodded. ”I know,” from what Rover Rover's crew had told her. Neither they nor Eisenberg were weaklings, but kzinti captivity was at best unnerving. Given a stiff enough emergency, you could force yourself to carry on for a while. Thereafter medications merely helped time and nature. Eisenberg was absolutely right to disqualify herself for another week or two.

”And autopilot won't do for the other, not when we are bound to be surprised and must react fast if we are to collect the data,” Raden went on. ”I shall have to steer.” Even now, she heard the relish.

”Exactly,” Tyra said. ”In that case, you can pick who comes with you, can't you? If you make a point of it.”

”Well, I see where it could give you a spectacular story. But no, the hazard-no.”

”What hazard?” she challenged. ”You're skilled, you're not a fool, you won't take unnecessary risks.”

”Not knowingly. Still, who can foresee what happens?”
