Innelda and Marcus turn in a positive report. Everything their instruments have told them leads to the conclusion that Planet A is a good bet for colonization. There is water at least in moderation; there is air that is recognizable as air; the gravity is okay; at least in a general way the place appears to be capable of sustaining life, Earth-type life. But on the other hand, it is not possible to detect the presence of higher life-forms already in possession of the place. There are no cities visible from up here, no roads, no construction of any sort. No radio emission comes from Planet A, or anything else in any part of the whole electromagnetic spectrum. No artificial satellites are in orbit around it. All this is to the good. It is not the intention of the voyagers to move in on thriving alien civilizations and conquer them, or even to wheedle permission with gifts of beads and mirrors to settle among them. The Articles of the Voyage specifically state that the Wotan is to refrain from making landings on any world that is seen to be inhabited by apparently intelligent beings, leaving the definition of “intelligent” up to the year-captain, but making it quite clear that any sort of intrusion on a going civilization is definitely to be avoided.

There are, presumably, enough habitable but uninhabited worlds available within relatively easy reach to make such an intrusion not only morally undesirable but also unnecessary. This may or may not be the case, the travelers realize, but it is a good working assumption with which to begin their galactic odyssey. There are those on board who have already pointed out that policies can always be revised, much farther down the line, if circumstances demand such a revision.

The year-captain is suspicious, of course, of the encouraging data that Marcus and Innelda have brought him. It is inherent in his wary nature that he will believe that it is much too good to be true that the very first planet they have located should conveniently turn out to be suitable for colonization. Unless, of course, every solar system in the galaxy has one or two Earth-type planets in it — but in that case, why have there been no signs thus far of intelligent life anywhere in the galactic neighborhood? If there are millions or even billions of Earth-type worlds in the galaxy, is it at all probable that Earth itself should be the only one of those worlds to evolve a civilization?

So, then: Is Earth, that green and pleasant world, the one-in-a-billion galactic fluke, and, if so, how come they have struck a second such fluke so easily? Or are there planets of this kind all over the place and it is the human race itself that is the improbable statistical anomaly? The year-captain has no idea. Perhaps there will be some answers later on, he thinks. But he is made definitely uneasy by the swiftness with which they have discovered this apparently habitable but evidently uninhabited world.

The action now shifts to Huw’s department. He is the chief explorer; he will mount and launch an unmanned probe to provide them with actual and tangible samplings of the planetary environment that awaits them.

The Wotan carries three robot drones, and has the technological capacity to assemble others if anything happens to these. But constructing replacements for the original three would require a considerable redeployment of the ship’s resources of matériel and energy, and Huw understands very clearly that every effort must be made to bring each drone back successfully from a launching. He runs simulated landings nonstop for three days before he is ready to send one of the little robot vessels forth.

The outing, though, is carried off perfectly. The drone emerges smoothly from the belly of the starship and spirals downward to its target with absolute accuracy. Taking up an orbital position some 20,000 kilometers above the surface of Planet A, it carries out an extensive optical reconnaissance, sending back televised images that continue to provide confirmation for the belief that no higher life-forms are to be found down there.
