The Nadine was out of overdrive and all the uncountable suns of the galaxy shone steadily, remotely, as infinitesimal specks of light of every color of the rainbow. Two hours since, the sun of this solar system had been a vast glaring disk off to port, with streamers and prominences erupting about its edges. Now it lay astern, and Moran could see the planet that had been chosen for his marooning. It was a cloudy world. There were some dim markings near one lighted limb, but nowhere else. There was an ice-cap in view. The rest was—clouds.
The ice-cap, by its existence and circular shape, proved that the planet rotated at a not unreasonable rate. The fact that it was water-ice told much. A water-ice ice-cap said that there were no poisonous gases in the planet's atmosphere. Sulfur dioxide or chlorine, for example, would not allow the formation of water-ice. It would have to be sulphuric-acid or hydrochloric-acid ice. But the ice-cap was simple snow. Its size, too, told about temperature-distribution on the planet. A large cap would have meant a large area with arctic and sub-arctic temperatures, with small temperate and tropical climate-belts. A small one like this meant wide tropical and sub-tropical zones. The fact was verified by the thick, dense cloud-masses which covered most of the surface,—all the surface, in fact, outside the ice-cap. But since there were ice-caps there would be temperate regions. In short, the ice-cap proved that a man could endure the air and temperature conditions he would find.
Moran observed these things from the control-room of the Nadine, then approaching the world on planetary drive. He was to be left here, with no reason ever to expect rescue. Two of the Nadine's four-man crew watched out the same ports as the planet seemed to approach. Burleigh said encouragingly;
"It doesn't look too bad, Moran!"
Moran disagreed, but he did not answer. He cocked an ear instead. He heard something. It was a thin, wabbling, keening whine. No natural radiation sounds like that. Moran nodded toward the all-band speaker.
"Do you hear what I do?" he asked sardonically.
Burleigh listened. A distinctly artificial signal came out of the speaker. It wasn't a voice-signal. It wasn't an identification beacon, such as are placed on certain worlds for the convenience of interstellar skippers who need to check their courses on extremely long runs. This was something else.
Burleigh said:
