СКАЧАТЬ Chetwynd, and Tam each took turns to gawk, silently jockeying to keep Commissioner Keefer last in line, since he had already spent more than his share of time at the observation scopes.

      Keefer simply sat back in his webbed relaxation seat with an inward smile, feeling at peace.

      Mars. At last.

      He had been only twenty-eight when he had begun working with the United Nations Space Agency on the terraforming efforts. He had served with the ground support staff on Earth, watching the first manned landing in many years. The small multinational team of explorers had collected geological samples, taken data on how much hydrated water in the rocks was boiling out and how much permafrost was thawing and oozing into the soil to chart the progress of the terraforming efforts, already several decades under way. The mission specialists had endlessly imaged sun-exposed outcroppings and sheltered crannies, cataloging which species of the robotically introduced simple plants were gaining a foothold. The astronauts had returned to Earth to a genuine ticker-tape parade, leaving Mars to continue its slow and inexorable progress toward paradise.

      Only four years after that, Dr. Dycek and her team from the Sovereign Republics had thrown everything into confusion with the surprise landing on Mars of the adins—monstrously altered human beings—long before any humans were expected to live on Mars. …

      Tam Smith moved away from the viewport and gestured for him to look, her wispy blond hair crackling around her head with static electricity. “You’re not fooling anybody with that bored act, Keef,” she said with a smile. “Go ahead, take a look.”

      “Caught me,” he answered and launched himself out of the web chair. At the viewport he peered down through a wispy veil of thickening atmosphere, the faint milkiness of high cirrus clouds smeared out near the poles. The bloody-ochre surface carried a flush of olive color, the first heartbeats of new life. He realized he was grinning with glassy-eyed delight, and his enthusiasm was infectious. Ogawa and Shen were chuckling at him and whispering to each other.

      What other project could be so grand? Keefer asked himself. This sculpting task could make men approach the level of gods. They were remaking an entire world! This had been his dream since his adolescent years.

      Rubbing his black-brown eyes in the lounge’s dry recirculated air, Keefer stretched out to touch the insulated wall of the ship. He pushed away from the port, drifting toward the center of the room. Ogawa and Shen claimed his space to ogle the planet once more.

      History would eventually imbue the Mars project with the grandeur it deserved, although the apathy shown by Earth’s general population frustrated Keefer. People had no patience for long-term projects. What was a hundred years or so in the grand scheme of things? The universe itself would blink its eyes in astonishment at how Sol’s frozen fourth planet had suddenly exploded into life.

      Long before Keefer had even been born, governmental huckstering had finally brought about a flags-and-footprint manned mission to Mars that managed to accomplish real science as well as take care of the political obligations for worldwide viewers, including the “For All Mankind” plaque.

      But during the years of preparation and the actual landing, the world’s space agencies carefully avoided the question of what to do next. Was Mars destined to be a dead end, a dusty trophy like the Moon? The red planet had enormous resources, but the sheer distance and the travel times involved made it unlikely that anything available there could make a difference to lives on Earth.

      Seeing that the governments did not have their hearts in exploiting Mars, multinational corporations scrambled to put together their own resource expeditions. Though Keefer had no love for the sheer-profit-motivated industrial mindset, he did credit the multinationals with finally forcing the UN Space Agency into action, to secure a beachhead on Mars before the companies could. In a bold move UNSA absorbed and adopted the other fledgeling programs, arm-wrestled all the competing work into a pool of combined resources, and secured the backing of the major governments. Riding the wave of support, UNSA struck out on a century-long program to make the fourth planet more like Earth, to change its hostile environment so that people could live there.

      The terraforming process would be costly, but no more so than a handful of short-term missions to Mars. Terraforming involved merely a lot of time, a lot of tedious long-distance maneuvers, remote operations—and thinking on scales larger than anyone had ever tried before. …

      Keefer found a coffee tube in the wall locker, pulled the zip-tab that made it heat itself, then sucked on the nozzle, careful not to burn the inside of his mouth. He frowned at the taste—he had accidentally removed a tube with cream-and-sugar flavoring. “Want this?” he asked Tam, who took it from him, brushing his dry fingertips with hers, but he was too preoccupied to notice her flirtations this time. Keefer rummaged in the wall locker again until he found a tube marked CREAM ONLY, and sipped idly.

      Back at the viewport, shoulder to shoulder with the other four, Keefer saw how the orbit had carried them over Mars. Below stretched the gouge of Valles Marineris, the “grand canyon” of Mars, miles deep in places and wider than the entire United States. In the northern highlands, a giant whitewashed crater marked Encke Basin, the scar left by one of the comets that had been hurled into Mars as the first step in the terraforming process.

      UNSA had undertaken a rendezvous mission to Encke as the comet whipped close to Earth on its 3.3-year orbit, detonating precisely positioned nuclear warheads that sent Encke straight to Mars, where it grazed the atmosphere, aerobraking to slow its descent. Thus it burned up and dumped its contents into Mars’s atmosphere rather than ionizing all the gases into space. The comet strike brought with it cubic miles of free water, as well as enough energy of impact to warm the atmosphere. The shock wave and the heat imparted by the collision released an additional four times Encke’s water vapor from the soil into the air.

      The resulting Encke Sea had volatilized in only two years, but the changes in the Martian atmosphere were permanent. The upset in the climate and the brief greenhouse effect melted part of the ice caps, which increased the atmospheric pressure further, which melted more. …

      The escalation had begun. Mars had been locked in an unsteady climatic equilibrium, waiting for a shove from ambitious humanity.

      A year later two transports released samples of airborne algae—voracious for carbon dioxide—into the Martian atmosphere. The algae included a dozen different varieties genetically engineered to thrive on Martian conditions. They soaked up the weak sunlight, gathered minerals from the ever-present fine dust that whipped through the air, settled on exposed surfaces, and released bound oxygen. All this laid the groundwork for a terrestrial ecology. Two years later another cargo ship dumped more algae into the air, new strains. Monitors showed measurable improvements in the air concentrations.

      That was the year Keefer had been born.

      Six years after that, new algae and free-plankton strains were deployed, tweaked to optimize their metabolism in the changing environmental conditions, while the first species grew obsolete in an atmosphere becoming too rich for them.

      Nineteen years after the first cometary impact, a second iceball crashed into Mars. The long-period comet Harlow-Burris, previously undiscovered, roared down into the solar system in an orbit that would take it astonishingly close to Mars on its trip through the ecliptic plane. A frantic mission was set up to give Harlow-Burris a nudge and change its course just enough to smack it into Mars, dumping more water, adding more heat, freeing more of the locked moisture and oxygen buried beneath the sands and hydrated within the rocks.

      During Earth’s worldwide recession, when Keefer himself began working as a student in planetary geology, most of the cost-intensive terraforming work ground to a halt, but the wheels of nature СКАЧАТЬ
