“The conquest of space is what thrills me most. Partly because it’s the most difficult
achievement of human engineering, the most daring and the most dangerous. And
partly, I suppose, because my own descendants played a big part in it.”
An eager ring of enthusiasm had risen in his voice, and now he paused awkwardly, as
if suddenly self-conscious because of it. His sharp blue eyes searched my face. I kept
silent until he went on, sure that the least show of doubt would stop him.
“Yes, Doctor, I’ve a son.” His thin brown face showed a wistful pride. “I don’t see
much of him, because he’s a very busy young man. I failed to make a soldier out of
him, and I used to think he’d never amount to much. I tried to get him to join up, long
before Pearl Harbor, but he wouldn’t hear of it.
“No, Don never took to fighting. He’s something you call a nuclear physicist, and
he’s got himself a nice, safe deferment. Now he’s on a war job, somewhere out in
New Mexico. I’m not even supposed to know where he is, and I can’t tell you what
he’s doing—but the thesis he wrote, at Tech, was something about the metal
uranium.”
Old John Delmar gave me a proud and wistful smile.
“No, I used to think that Don would never accomplish much, but now I know that he
designed the first atomic reaction motor. I used to think he had no guts—but he was
man enough to pilot the first manned atomic rocket ever launched.”
I must have goggled, for he explained:
“That was 1956, Doctor—the past tense just seems more conven-lent. With this—this
capacity of mine, you see, I shared that flight with Don, until his rocket exploded,
outside the stratosphere. He died, of course. But he left a son, to carry on the Delmar
name.
“And that grandson of mine reached the Moon, Doctor, in a military rocket. After
uranium was discovered there, he went back to take command of the American
outpost—a little camp of air-tight domes, over the mines. But the ghastly atomic
wars, in the 1990’s, isolated the Moon. My grandson died there, with the rest of his
little garrison, and it was nearly two hundred years before human civilization was far
enough recovered from the wars to build another space rocket.
“But it was a Miles Delmar, late in the twenty-second century, who finally went back
to the dead mining camps on the Moon, and then set out for Mars. He left too much
shielding off his atomic reaction motor, to lighten his ship for that voyage, and the
leaking radiations killed him and all his crew. The dead ship carried the bodies on,
and crashed in the Syrtis Major.
“Miles’s son, Zane Delmar, patented the geodyne—which was a vast advance over
the heavy, dangerous atomic reactors. He found the wreck of his father’s ship on
Mars, and survived an attack from the native Martian beings, and later died of a
Venusian jungle-fever. The victory of men over space wasn’t easy—quite! But Zane’s
three sons carried on the war. And they made a huge fortune out of the geodyne.
“In the next century, all the solar system was pretty well explored, as far out as the
moon of Neptune. It was fifty years more before a John Ulnar reached Pluto—our
family name was changed, about that time, from Delmar to Ulnar, to fit a new
