"Sort of. More of a maintenance engineer than a design or development engineer. He seems to have specialized in military equipment—there's a long list of postings to combat units. The last one is interesting . . ." Maddson selected a sheet and passed it across to Hunt. "That's a translation of the last page of postings. The final entry gives the name of a place and, alongside it, a description which, when translated literally, means 'off-planet.' That's probably the Lunarian name for whatever part of our Moon he was sent to."

"Interesting," Hunt agreed. "You've found out quite a lot more about him."

"Yep, we've got him pretty well taped. If you convert their dates into our units, he was about thirty-two years old at the date of his last posting. Anyhow, that's all really incidental; you can read the details. I was going to run over the picture we're getting of the kind of world he was born into." Maddson paused to consult his notes again. Then he resumed: "Minerva was a dying world. At the time we're talking about, the last cold period of the Ice Age was approaching its peak. I'm told that ice ages are Solar-System-wide phenomena; Minerva was a lot farther from the Sun than here, so as you can imagine, things were pretty bleak there."

"You've only got to look at the size of those ice caps," Hunt commented.

"Yes, exactly. And it was getting worse. The Lunarian scientists figured they had less than a hundred years to go before the ice sheets met and blanketed the whole planet completely. Now, as you'd expect, they had studied astronomy for centuries—centuries before Charlie's time, that is—and they'd known for a long time that things were going to get worse before they got better. So, they'd reached the conclusion, way back, that the only way out was to escape to another world. The problem, of course, was that for generations after they got the idea, nobody knew anything about how to do something about it. The answer had to lie somewhere along the line of better science and better technology. It became kind of a racial goal—the one thing that mattered, that generation after generation worked toward—the development of the sciences that would get them to places they knew existed, before the ice wiped out the whole race."
