As she talked, David thought about Mars…and the Ship.
The Face on Mars had been carved by someone half a million years ago, someone who’d built a number of cyclopean structures in the area and apparently used humans imported from Earth to help with the construction. There was even evidence that some sort of massive terraforming project had been under way at the time; most surface features had been damaged or destroyed by a savage flood of liquid water. Many of the human bodies found so far showed evidence of having suffocated as their atmosphere—possibly contained in some sort of field or bubble—bled suddenly away. There was also evidence—lots of it—of a battle, an attack that had ripped open milewide pyramids and left the site in ruins. The Face itself was almost unrecognizable as an artifact carved by intelligence, though the general form and the neatly carved geometries were still visible beneath the rubble.
One of the more enigmatic sites at Cydonia was the hill known as the Fortress. Once, probably, it had been a pyramidal structure like some of the others in the area, but something more powerful than a thermonuclear bomb had sheared off the top, wrecked the inside, and reduced much of it to rubble. Later, a ship of some kind, a vessel over a kilometer long, had toppled onto the ruins, wracked by internal explosions. The wreckage, exposed to the sand-blasting of half a million years of Martian weather, was so poorly preserved it was impossible to learn much.
But the ruins—and especially the promise of the wrecked ship—had been responsible for the revitalization of the on-again, off-again vagaries of the US space program, and of the Russian Space Agency as well. Whoever had built the Cydonian complex had possessed the secret of traveling among the stars; a careful study of the ruins might bring that secret home to Earth.
And more than that. The Builders had been engaged in terraforming on a planetary scale; the ongoing deterioration of Earth’s environment, the coastal flooding and rising global temperatures, had been growing slowly but steadily worse for the past fifty years. The secret of planetary climate control might well prove to be more important, at least insofar as Earth’s continued habitability was concerned, than the secret of traveling to the stars.
And so the infant science of exoarcheology, and its bastard half brother, exotecharcheology, had been born.
On Mars, the problem had been the sheer scale of things, coupled with how damnably difficult it was to get there in the first place. By using a system of space stations, called cyclers, that alternately touched the orbits of Earth and Mars, it had been possible to get a few hundred people out to the Red Planet over the past decade or so to study the site; the trouble was, it would take thousands of people, working for years, simply to carry out a decent survey of the Martian ruins. It might well be centuries, yet, before Cydonia yielded the last of its long-held secrets.
But if some of those secrets also lay hidden on the Moon, just three or four days away, instead of the six to nine months required for a cycler passage to Mars…
“We can’t tell you everything that’s going on right now,” Sarah was saying. “Suffice to say that it has become an issue of national security. We need a trained archeologist’s assessment of the wreckage, and we need to have an idea of just what the UN scientists might have learned from it.”
“But why me?”
Roger shrugged. “That should be evident. You’ve been to Cydonia. You know as much about the Builders, about exotech, as anyone, and more than most. You are probably the field authority on ET artifacts and technologies.”
And, he thought with a touch of bitterness, I’m here, in your institute, bought and paid for. The other scientists who’d been to Mars—Kettering, Pohl, Vandemeer, and the others—had returned to their old positions, to promotions, to careers made more secure by their fifteen months on Mars. But David had had no place to go but…here. The Cydonian Research Foundation, a government-sponsored organization, had funded the Exoarcheological Institute to study the finds being uncovered on Mars.
And, perhaps, on the Moon as well.
The problem was that David’s reputation as something of a maverick in established archeological circles had made him the ideal candidate for exoarcheologist-in-residence here at the institute.
And it was damned hard to say no to a government-backed request.
“You’re also already rated for a pressure suit and pliss,” Sarah told him.
True enough. In fact, he’d already been to the Moon, briefly, as part of his astronautics training in preparation for his flight to Mars. He’d spent three days at Fra Mauro and been bored most of the time, even with a crowded training schedule.
“Can I take anyone along? Dr. Sullivan has been working with me on…”
“I’m sorry, Doctor. Space is limited, and there’s no time for training.”
Teri was going to be disappointed. Hell, he was disappointed…but the thought of getting into the field again—and on the Moon!—was too much to resist.
Besides, he knew what LEO-Lunar transports were like. There’d have been no privacy, no opportunity to give Teri a chance to join the Three Dolphin Club.
Later, after his visitors had left, David stood at the window looking down at the demonstrators outside, thoughtful. There was someone he needed to talk to just now.
Someone he wasn’t supposed to talk to at all….
EU Science Research Vessel
Pierre-Simon Laplace
Co-orbit with Asteroid 2034L
2235 hours GMT
Dr. Jean-Etienne Cheseaux floated alongside the Laplace’s tiny observation port, slipping his dark glasses into place as sunlight flooded into the compartment. Outside, the sun was just clearing the edge of the Rock as the ship’s slow drift brought her clear of the small planetoid’s shadow. He still wondered why the Académie des Sciences had insisted that he come here.
Cheseaux was an astronomer; his primary specialization was selenology, the geology of the Moon, but the Academy had asked him to serve as payload specialist aboard the Laplace. Not that he was complaining, necessarily—he liked it in space, enjoyed the sensations of free fall and the spectacular purity of the sunlight—but the measurements he was taking of 2034L’s mass and spin and precise orbit could have been made by any competent technician. It was, he supposed, an indication of the importance the Academy attached to this mission. The knowledge stirred his professional pride, and his ego; there was talk, he’d heard, of naming this particular rock Cheseaux. Of course, the astronomical society frowned on using the names of living people, but there were precedents.
Asteroid 2034L had been discovered eight years ago, one of the fast-growing number of near-Earth asteroids whose orbits carried them periodically inside the orbit of Earth. This one was particularly disturbing; as carbonaceous chondrite, like the majority of asteroids, it had an extremely low albedo, rendering its surface as black as the blackest coal. It was also small, less than a hundred meters across.
That combination of orbit, albedo, and small size made 2034L particularly dangerous, a prime target for the Phaeton Project. In Greek mythology, Phaeton was the boy who’d lost control of Apollo’s sun-chariot, bringing it too near the Earth and nearly destroying humanity in fire. Since the 1980s, the particular danger Earth-crossing asteroids and comets represented to the Earth had been well understood; the lesson of the dinosaurs, exterminated by the ten-mile body that had smashed into the Yucatán sixty-five million years ago, could not be ignored. By the early 2000s, several skywatch operations were in place, identifying and charting the flying mountains that might someday pose a direct threat to Earth and her inhabitants.
Phaeton, one of the most comprehensive of the sky-watch programs, had been begun in 2029, a collaboration between the European Union, Japan, and the United States. The UN had assumed financial responsibility five years later, the same year in which 2034L had been discovered. The war, of course, had interfered
