He deliberately broke off in mid-sentence to measure what effect his words would have on the wide-eyed, incredulous Pirx. Slowly the cadet drew a solemn breath, held it, and sat there as if oblivious of the need to exhale. Blushing like a maiden at the sight of her Prince, he waited for another dose of sweet-sounding phrases. The commandant cleared his throat.

“Well, well,” he said soberingly, “I may have been exaggerating. Anyway, you’re mistaken.”

“Beg your pardon?” stammered Pirx.

“I mean you’re not the world’s only salvation. Not yet, at least.”

Pirx, red as a beet, squirmed in his seat and fidgeted with his hands. The commandant, a man notorious for his methods, had just finished painting a paradisiacal vision of Pirx the Hero (Pirx already had dreams of returning from his Heroic Exploit and, while being paraded through a packed cosmodrome, hearing awed whispers of “That’s the one! That’s the one!”), and now, unknowingly it seemed, he was beginning to play down the Mission, to trim it down to the size of a routine training assignment.

“The station is manned by astronomers—they’re sent out there, do their month’s service, and that’s that. The work is routine, requiring no specialized skills. Candidates used to be screened on the basis of the standard first- and second-degree tests. But that was before the accident. Now we need people who have undergone more rigorous testing. Pilots would be ideal, but you can’t very well farm a pilot out to a routine observatory. You can understand that.”

Pirx could understand. The whole solar system was begging for pilots, astrogators, navigators—always in short supply, even in the best of times. But what “accident” was the commandant referring to? Pirx observed a prudent silence.

“It’s a small station, situated in the most cockeyed place imaginable—not on the crater floor, as you’d expect, but just below the northern summit. There was a big to-do about the choice of location, international prestige rather than sound selenophysics being the deciding factor—as you’ll see in a moment.
