VIII


The Corianis had vanished between Kholar and Mani-nea. After the fact was discovered, it took a mere few hours to get a space lifeboat out of atmosphere with a spectrotelescope on board to watch for the iron-atom cloud in emptiness which would be a plea for aid, and only two days and a few hours were needed to get the news back to Kholar. On the way back, the mail-ship which took the news may have passed within light-hours of the spot where the Corianis had collided with a celestial scrap-heap. But it was not equipped for search.

By the time the Corianis was four days overdue, a trampship took off from Maninea; it also was equipped with a spectrotelescope. It began, methodically, to make short hops in overdrive along the line the Corianis should have followed. Each time it came out of overdrive it made a search. It searched from three light-days from Maninea and six, and twelve, and so on. It did not really expect to pick up a distress-signal so early. An iron-atom cloud would be relatively small so soon after its presumed formation. But it would enlarge, and the fact that it would also thin out didn't matter.

That first hunting ship from Maninea reached Kholar. No news. It was joined by another ship which had come into port. The two ships spaced themselves some light-minutes apart and headed back for Maninea; they reached it without any discovery. Two other ships had arrived from other worlds in response to the shipping service's request. Four ships headed back for Kholar.

Empty space is dark. The firmament glitters with innumerable stars, of all the colors that light can be; but the total light is faint, and where there is no sun it is very, very lonely. Each of the ships making multi-billion-mile casts through emptiness seemed utterly solitary. A ship came out of overdrive to unstressed space. It located the sun Kholar. It focussed a spectrotelescope upon a five-degree square area of space with Kholar at its center. It turned on the scope. Only stars with strong absorption-lines in their spectra would appear in the scope-field. They were examined separately. If or when one of them showed the lines slightly widened, it would indicate that iron existed between the star and the ship. Then there must be a cloud of iron particles in space -a signal of distress.

A little more than halfway across, a ship from Ghalt- the last ship to join in the search-found the telltale widening of iron-spectrum lines in the light of Kholar itself. It aimed for the cloud and jumped for it. It overleaped. It went back. It found the cloud-and danger-signals clanged inside it. The iron-atom cloud was then two and a half million miles in diameter. The ship sought its center; it found debris floating in space. It measured the iron-vapor cloud and computed its mass. There was too much vaporized metal to have come from a signal-rocket's substance; there was not enough to say that the Corianis itself had broken down to atoms.

The ship began to examine all the debris its radars picked up. It found some rocky and many metallic masses; some were the size of houses. There was a dense cloud of still larger metal lumps. Its parts were in motion, as if it had only recently been jolted by something enormous.

The first ship was joined by a second, which also had found the iron-cloud. Later a third ship drove up and joined the search.

They did not find the Corianis. They did find a mountain-sized mass of metal, on one of whose flanks there was a circular, hollow, glistening scar, as if some incredible blast of heat had burned or boiled away the metal there. Rough estimate suggested that the amount of metal boiled away at this spot might account for the metal-cloud.

It did. An analysis of the cloud's substance disclosed nickel in considerable quantity with the iron. A measurement of the cloud's expansion gave the time of its beginning to expand-its creation.

The iron-cloud did not come from the Corianis' hull or signal-rocket. It was not iron alone; it was a nickel-iron cloud. It was metal vaporized from a mass of metallic debris. It had been vaporized at the time the Corianis had passed through this part of emptiness. Here, then, was where the Corianis had vanished.

But there was no trace of the ship itself, though one or another of the three ships examined every particle of solid stuff within thousands of miles.

The search-ships, though, had done a remarkable job; they'd located the scene of a disaster in space. The ship involved could not be found-but to pinpoint even the place where a ship had been wrecked was more than had ever been accomplished before.
