and water masses," Castor said.
"I don't know what could have stripped it so completely," Ben said.
"You never did like the Hoyle Wickramansingh theory, did you?"
"Has anyone ever found those space-formed viruses? Even a trace in any
Oort cloud?" Ben stuck his chin out with a touch of belligerence. "I won't
buy that space-virus theory, not when a planet is covered with city-sized
craters. To have both would be overkill, and the universe is conservative.
One gets you just as dead as the other."
"I searched the library for data on other stripped planets. Asturias
matches up on every particular," Liu said, his eyes on the screen. "What
particulars there can be, that is!" He rose, stretched, and yawned broadly.
"What we really need is one in the process of being stripped."
Shavva gave a bark of laughter. "Fat chance of that."
Liu shrugged. "Something does it. Anyway, I feel that the virus theory
would be the rarest probability, while meteors are common, common, common.
Look at what happened in our Earth's Cretaceous and Tertiary periods. We were
just lucky! Probes away, Captain," he said formally to Castor. "Now, I'm for
something to eat, then I'll pack the shuttle for the shot."
"I'll give you a hand," Shawa said. "I want to be sure we got what we
need this time," she added in a low, angry voice, bitterly aware that it had
been Flora's own negligence that had cost those two lives. Shavva was now the
default leader of this understaffed team, and she was determined not to repeat
previous mistakes.
As a young biologist with latent qualities as a nexialist, she had
joined the Exploration and Evaluation Corps for the diversity of duty and the
thrill of being the first human to walk on unexplored planets and catalog new
life-forms, but she hadn't counted on losing friends in the process. EEC
teams developed very close bonds, having to rely on each other's strengths and
weaknesses in dangerous, stimulating, and testing circumstances no textbook,
indeed often no other team reports, could imagine. This was her fourth tour
of duty but the first one punctuated by disasters. Now all the fieldwork
would have to be accomplished by three people--herself, Liu, and Ben--while
Castor, still handicapped by his leg injuries, remained on board as the
exploratory vessel did its hairpin turn about the third planet.
Shavva would have to double as botanist on this trip. Fortunately she
had learned enough from Flora to be able to determine a fair amount about the
ecology of the plant life--if there were sufficient pollinators, what sort of
competition there was for the food crops, as well as the nutritional
possibilities of the native forms, and quite likely what disease agents and
possible vectors existed within the ecology.
Ben, as a geologist with some secondary background in chemistry, could
cope with the planet's basic pulse--its air and landmasses, magnetic fields,
mass-cons, continental plate structure, tidal patterns, temperatures, the
general topography, and, especially, any seismic activity--and evaluate the
history of the planetary surface for at least the past million years. If the
survey proceeded without glitches, he'd have a go at the longer-term history,
attempting to detect signs of magnetic reversals and to determine if--and
when--there had been any large extinctions.
Liu, as nexialist, would investigate whatever remaining aspects of this
planet they had time to consider. That is, if the probes brought back reports
that would make a visit worthwhile. Numero Tres did look promising, but
Shavva had discovered that looks could be very deceiving in this business.
The probe sent back reports that were skeptically regarded as being too
good to be true.
"Good balance of land and water masses," Liu said. "Usual ice caps,
mountains, good plains areas Parallels Earth in many respects. Initial P.E.
for starters, Castor."
"Atmosphere is breathable, slightly above normal in oxygen content:
gravity slightly lower at zero-point-nine on the scale," Ben contributed.
"Considerable volcanism in that chain of islands extending from the southern
