Dr. Dmitri Pchanskii himself, a talented Belorussian obstetrician and
surgeon, had set an example as the leader of the fourth group of _dvas_.
Watching his outspoken commitment, other medical professionals and scientists
volunteered for the extreme surgery, with the justification that becoming a
_dva_ would be the best way to do research on an alien world. After the
surgeries, they could be part of the environment, studying Mars hands-on, the
same way field researchers studied Earth.
Firebrand legal representatives for the _dvas_ had even demanded of the
UN that their clients actually "own" the land they worked, not just receive
lifelong leases. A Volga German lawyer named Rotlein had played on public
sympathies -- everyone admired the _dva_ bravery, especially after learning of
the horrors that had befallen the _adin_ phase. Why not throw the _dvas_ a
bone? The _dvas_ would probably not live long in such a harsh environment
anyway....
For a time, the _dva_ project appeared to be a complete success. Over
the years, the _dvas_ had received enormous, robotically piloted shipments
containing the modules for Lowell Base and the four other human bases
scattered across the surface of Mars. Before the first unmodified humans
arrived to stay, the _dvas_ completed all the prep work, like servants sent
ahead to prepare the master's room. Three years after the last _dva_ landing,
Rachel and fifty others arrived at Lowell Base to prepare for the "Grand
Opening" of a terraformed Mars.
But, when a project was as large as an entire planet, the work never
ended. Pchanskii's team of _dvas_ had been searching for subterranean water in
Noctis Labyrinthus. But Pchanskii had been a surgeon on Earth, not a geologist
or a construction engineer. He had not understood what he was doing when he
blasted the fragile rocks.
When Lowell Base received no progress reports from them for several
days, and with a large seasonal dust storm approaching, Rachel had dispatched
a search team. She herself had rushed out on the rescue mission, as others
watched the green-and-pink skies thicken with approaching waves of dust.
Rachel had stared at the fallen rocks, the sheared-off cliffs, and the fine
dust that refused to settle, whipped back into the air by precursor gusts of
wind.
As much as a week could have gone by since the collapse; little wonder
they found no survivors, no sign at all.
With grim irony, Pchanskii's avalanche had exposed a rich vein of water
ice that looked like a steaming white gash on the rock. It created a thick,
temporary fog in the canyons as the ice sublimed in the thin air....
The weather satellites politely advised everyone to take shelter at the
base and ride out the storm. The rescue team, unable to recover _dva_ bodies
or precious equipment from under tons and tons of rock, was forced back to the
base. Later, after the abrasion from the month-long storm, there had been
little point in even looking.
Pchanskii's group had been swallowed up by the tumbling walls of rock,
but Rachel was left to face the avalanche of recriminations, and
"I-told-you-so's", and the sadly shaking heads. She had endured it, barely
flinching, with no more than a tic in the right eye and a grim twitch at the
corner of her wide mouth.
She could no longer deny that the entire _dva_ project, her brainchild,
was at an end, with only a few messy loose ends to tie up: 150 _dvas_ still
toiling on the surface of Mars, while spacesuited humans plowed ahead with
their own work. In a few more decades, neither surgical augmentations nor
environmental suits would be necessary to survive in the cold, brittle
atmosphere. The remaining _dvas_ were obsolete, the program a dead end, and
they would live out their lives on Mars with no hope of returning to Earth.
Now, Rachel's decade as commissioner seemed like such a grand folly.
She stared at the motionless rubble in the canyon and listened to the whispers
of wind and the burbling of her air-regeneration system.
In the first launch opportunity from Earth after the _dva_ disaster,
