There were two small circular windows, one to either side of her. Now there was only darkness within them, because the spacecraft—perched here a hundred and seventy feet above the ground at the tip of the Long March booster—was enclosed within its protective fairing. But there was a small periscope, its eyepiece set in the center of the instrument panel before her, whose extension poked out beyond the fairing.
Seen through the periscope, the sky was a vast blue dome, devoid of moisture.
This was Inner Mongolia, the northeast of China. The desert was a vast, tan brown expanse, as flat as a table-top, stretching to the horizon in every direction. Beijing was hundreds of miles east of here. To the north, beyond the shadow of the Great Wall, camel trains still worked across the Mongolian Gobi.
The Jiuquan launch center itself was modest. There were just three launch pads set in a rough triangle a few hundred yards apart. The pads were concrete tables, a hundred feet across, with minimal equipment at each; there was a single gantry almost as tall as the Long March booster itself, which was moved on rails between the pads. She could see the railway spurs which brought booster stages here. There was no surrounding industrial complex, as at Cape Canaveral or Tyuratam. There was only an igloo-like blockhouse close to each pad, buried partly underground, containing the firing rooms; further away there were gleaming tanks and snaking pipelines for propellant storage and delivery, and a small power station.
The launch complex, in fact, was dwarfed by the thousandmile hugeness of the Gobi.
To Jiang, the elemental simplicity of this facility was its power. Here in the mouth of the desert it was as if her booster had barely any connection with the Earth it was soon to shake off. To Jiang, Jiuquan was the reality of spaceflight, reduced to its core…
The flight was still to come, of course. But already, she sensed, the worst of her mission was over: the public tours, the attention from TV and net correspondents, the speeches to thousands of Party cadres in Tiananmen Square, even the meeting with the Great Helmsman himself. Of course there would be many more such chores after the flight, but that was far from her mind.
For now she was alone in here, contained within the xiaohao—in this environment she had come to know so well. Here, she was in command, and she was ready to confront destiny: to become the first Chinese, in five thousand years of history, to break the bonds of Earth itself.
A voice crackled in the small speakers on her headset. “Lei Feng Number One from the firing room. Are you ready to begin your checklist?”
She was still clutching the brass bell. She reached up, and fixed it to the handle of the hatch above her with a twist of wire. She touched Mao’s face with a spacesuited finger. The bell rang gently. She smiled. Now, ta laorenjia could protect her as he did millions of Chinese; Mao Zedong, three decades after his death, had become the most popular household folk god.
She settled back in her couch. “This is Jiang Ling in Lei Feng Number One. Yes, I can confirm I am ready to proceed with the checklist. Today is a good day to fly!”
The work seemed to come in waves, with clusters of switches to throw and settings to check in a short time. In addition she had to record measurements in her log book. And she had to work to reduce the condensation inside the cramped compartment. In orbit this would be done automatically, but on the ground the light pumps were overwhelmed by Earth’s gravity, and she had to open and close valves at set times, and she had a little hand-pump she used to move condensate from one part of the cabin to another.
There were several long holds in the countdown, when malfunctions were encountered. During these periods she had literally nothing to do, and she found them difficult times.
She was aware of continual movement and noise. She could feel the rocket swaying as the thin desert wind hit its flanks; and there was a succession of thumps, bangs and shudders, as ancillary equipment was moved to and from the booster. She was very aware that she was suspended at the top of a thin, fragile steel tower housing thousands of tons of highly explosive propellant.
There were cameras all over the cabin, focused on her face behind its open visor, their black lenses glinting in the floods. She tried to keep her expression clear, her movements calm and assured.
She felt a deep nervousness gnaw at her, more worrying even than the prospect that some catastrophe might claim her life, today. If something went wrong, if the mission was aborted, was it possible that she would somehow be blamed?
Jiang was not Han Chinese. She was a Turkic Uighur, a Muslim minority which emanated from the westernmost province of Xinjiang. Jiang’s family came from the desert capital Urumqi; her family had moved to Beijing when she was a child when Jiang’s father, a mid-ranking Party cadre, was posted to the Minorities Institute in the capital in the 1970s. Since her father was both an official and a Uighur, the family had been treated with a special deference reserved for select representatives of minority groups who served as symbols for the Party’s efforts to build “socialist solidarity” between central China and the non-Han regions. In Beijing, Jiang had attended a special “experimental” school reserved for the children of the Party élite.
Among the Han astronaut trainees there had been some resentment at her promotion—sometimes suppressed, sometimes not. And there had been genuine surprise when she had been selected for the honor of this first flight, ahead of the Han candidates.
Jiang believed that it was on the basis of her superior abilities. Perhaps that was true. But she knew that she could not help but accrue rivals and enemies, now, as she moved into national, even international prominence.
Meanwhile the xiaodao xiaoxi—the back-alley scuttlebutt—was that the Chinese space program, in its thirty-year history, had already killed five hundred people. Even worse, it was said, one astronaut had already lost his—or her—life, in a clandestine suborbital test of the Lei Feng-Long March system.
Jiang Ling believed some of this, but not all. She would be a fool to try to deny that she was exposing herself to enormous risks, here in the Lei Feng. Perhaps more risks than any other astronaut from East or West since the first pioneers themselves.
But for Jiang it was worth it. And not for the glory for being what the People’s Daily called a jianghu haojie, a modern-day knight errant—and certainly not for the “iron rice bowl” which her status afforded her. To Jiang, it was simply this moment, the hours and days to come: to be thrust into orbit, to look down on the Earth like a glowing carpet below. To Jiang, that was worth any risk.
As she’d come to the pad, a technician had told her the Americans were claiming to have found life on Titan, moon of Saturn.
Lying here now, Jiang tried to absorb the news. What could it mean? Could it be true?
In the end she dismissed the speculation. What value was a mission to Saturn? What use was life on Titan, even if it existed? Perhaps the stars were for America, but Earth was for China.
And now the holds started to clear up, and her mood lifted.
Jackie Bcnacerraf didn’t know what to expect of JPL. She certainly didn’t rely on the descriptions from her mother, the famous spacewoman.
She drove. her hired car out along the Glendale Freeway, out of downtown LA, along tree-lined roads. She drove through swank suburbs, following the softscreen map in the car, and was surprised when she rounded a turn, and came upon JPL.
At first glance JPL could have been any reasonably modern corporate or college site, maybe a hospital: it was spread over two hundred acres, nestling in the eroded, green-clad shoulders of the San Gabriel Mountains, the blocky office buildings interspersed with Southern California palms. She caught glimpses of some kind of campus inside the security fences, fountains and trees.
But the roads here were called Mariner Road, and Surveyor Road, and Ranger Road. For the Jet Propulsion Laboratory had built and run spacecraft which had reached every planet in the Solar System, save only Pluto. And, right now, the scientists here were gathering information from the moons of Saturn.

sp; She parked her car. Isaac Rosenberg was there to meet her at the visitors’ reception. “Jackie. Thanks for coming in.”
“Isaac, it’s good to meet you again.”
He pushed his John Lennon spectacles a little further back up his nose. “Rosenberg. Everybody calls me Rosenberg.”
“Rosenberg, then.”
He was somewhere in his mid-twenties, she figured, maybe a couple of years older than she was. He didn’t look as if he lived too well; his face was pale and badly shaved, and his prematurely thinning black hair, none too clean, was tied back in a pony tail.
But none of that mattered, compared to the look in his brown eyes.
He said, “Thanks for coming out. Listen, you want me to get you a coffee? A doughnut, maybe?”
“No, thanks, Rosenberg. I want you to tell me about your results. At the party the other night, you were so—”
“Out of it.”
“Were you serious? Are the press reports true? How come the official spokesmen won’t answer questions on it?”
“Come see the results for yourself.”
He led her through the reception area and across the campus, to a long, low building he called the SFOF, for Space Flight Operations Facility. He took her up to the second floor, to a big windowless loft of a room, painted gray, with gray carpeting. It was divided up into rows of cubicles, within which worked—Rosenberg said—the engineers and scientists who controlled Cassini’s systems. So this is a spacecraft control center, she thought. It was about as lively as a bank’s back office.
They crossed the engineering room, and then passed through a hall to a science area, and entered a new warren of cubicles, the science back room. Rosenberg took her to his own cubicle, which was cluttered up with papers and rolled-up softscreens and an old-fashioned hard-key calculator. There were reproductions of the covers of antique science fiction magazines taped to the cubicle walls, she saw: By Spaceship to Saturn, and Raiders of Saturn’s Rings, and Missing Men of Saturn
He showed her a Packard Bell softscreen, stuck to one wall, which was cycling through displays of what turned out to be a thermal profile through Titan’s atmosphere, as sampled by the descending Huygens lander. Grabbinga mouse, he cleared down the screen and pulled up data from a fresh database.
She’d met him a few days before at a party at her old sorority at Caltech, where he was getting steadily drunk on ice beer and talking too much, loud and fast and humorlessly, about his work here at JPL on the Cassini/Huygens mission. He’d attracted a rotating audience of student types, some intrigued, some argumentative; as the group cycled, Rosenberg would happily launch into his obsessive monologue again, as far as Jackie could tell pretty much from the beginning.
He was talking about biochemistry—the chemistry of life—on Saturn’s moon, Titan.
Jackie was intrigued. Here was a classic loser magnet, but with a story of such compelling intensity that it was attracting a crowd, if a transient one. And she got even more interested, when the sensational claims about life on Titan had started appearing in the press and the net.
She was in the middle of a new effort to revive her once-promising career in journalism, which had been pretty much dormant since her second kid was born. If she was going to progress, she knew, she was going to have to develop a nose for a story, her own story, something dramatic and compelling—but out of the way, far from the attention span of the big boys.
And maybe—she’d thought, listening to this skinny monomaniac mouthing off to a bunch of strangers about weird chemistry results from Titan, and with his eves shining—maybe, she’d found it.
Before the end of that party she’d buttonholed Rosenberg and arranged to meet him here, at JPL. She’d figured it was a better than evens chance that he would have forgotten all about her, in which case she would have driven all this way out here to the arroyo for nothing. But when she’d arrived at the security gate, she found he’d left a media pass for her to collect.
Soon the softscreen was covered by chemical, notation and complex molecular structure charts.
He said, “How much biochemistry do you know?”
Actually, she’d picked up a little in her graduate days. But she said, “Nothing.”
“All right. I’m working in the group responsible for the GCMS results.”
“GCMS?”
“Gas chromatograph and mass spectrometer. In-situ measurements of the chemical composition of gases and aerosols in Titan’s atmosphere, and at the end of Huygens’s descent, a direct sample of the surface. The lead scientist is a guy at Goddard. On the lander, a slug sample was drawn in through filters and into an oven furnace, which—”
“Enough. Tell me what you do.”
“I’m working on high atomic number results. Complex molecules. Look—what do you know about conditions on the surface of Titan?”
“Only what I’ve seen in the pop press the last few weeks.”
“All right. Titan is an ice moon, with a thick layer of atmosphere. The only moon with a significant layer of air, anywhere. In a lot of ways, Titan right now is like primeval Earth—say, four and a half billion years ago. Its chemistry is mostly based around carbon, hydrogen and nitrogen. And chemistry like that produces a lot of the key molecules of prebiotic chemistry.”
“Prebiotic?”
“The components of life. But there’s a crucial difference. Titan has no liquid water. It’s too cold for that. The importance of water on primitive Earth is that it was a solvent. It allowed the polymerization of volatile reactive organics and the hydrol ysis of prebiotic oligomers into biomolecules… I’m sorry. Look, you need water as a solution medium, so that the components, the building blocks, can assemble themselves into proteins and nucleic acids, the main macromolecules of our form of life.”
Our form of life. That phrase made her shiver. “But maybe there are other solvents.”
“Correct. Maybe there are other solvents. In particular, ammonia. And we knew before Huygens that there is ammonia on Titan. Now. Look here. Look what the Huygens GCMS found.” He pointed to a diagram of a molecule shaped like a figure eight on its side, with some of its edges highlighted in blue for double covalent bonds.
“What is it?”
“Ammono-guanine. That is, guanine with the water chemistry systematically replaced by ammonia.” He looked up at her, the multicolored diagram reflected in his glasses. “Do you get it? Exactly what we’d have expected to have found, if some ammonia-based analogue of terrestrial life processes was going on down there. Look at these ratios.” He pulled up another image. “See that? Here, close to the surface, you have a depletion of methane and gaseous nitrogen, and a surplus of ammonia and cyanogen, compared to the atmosphere’s average. The analogy is clear. Methane and nitrogen are being used in place of monose sugars and oxygen, and you have ammonia and cyanogen instead of water and carbon dioxide—”
“What are you saying, Rosenberg?”
“Respiration,” he said. “Don’t you get it? Something down there has been breathing nitrogen, and exhaling ammonia.”
“So, could it mean life?”
He looked puzzled by the question. “yes. That’s the point. Of course it could.”
She frowned, staring at the molecular imagery. It was exciting, yes, but it was hardly the electric thrill she’d been hoping for. Even those blurred images of the microfossils in that mete orite from Mars had had more sex appeal than this obscure stuff.
“What do you think we should do about this?”
“Send another probe, of course,” he said, staring into the screen. “It ought to be a sample-return. We’ve just got to follow this up. Look at this.”
He studied his results, and Jackie studied him.
Right now, her own mother was on orbit, in Columbia.
In the long months of her mother’s work absences, Jackie had often wondered why it was always people with no life of their own on this planet—Rosenberg, her own mother after her lawyer husband walked out with his secretary�
��who became obsessive about finding life on others.
Anyhow it was academic. The funding just wasn’t there. Maybe not for the rest of your working life, Rosenberg, she thought sadly. This data, here, might be all you’ll ever see.
Rosenberg flexed his fingers, as if itching to thrust them into the ammonia-soaked slush of Titan.
“Lei Feng Number One, there are five minutes to go. Please close the mask of your helmet.”
Jiang obeyed, locking the heavy visor in place with a click of aluminum. “My helmet is shut. I am in the preparation regime.”
“Four minutes and thirty seconds to go.”
As her helmet enclosed her she was aware of a change in the ambient sound; she was shut in with the sound of her own voice, the soft words of the launch controllers in the firing room, the hiss of oxygen and the scratch of her own breathing.
Impatience overwhelmed her. Let the count proceed, let her fly to orbit, or die in the attempt!
Still the holds kept off: still she waited for the final, devastating malfunction which might abort the flight completely.
But the holds did not come; the counting continued.
The voices of the firing room controllers fell silent. There was a moment of stillness.
Jiang lay in the warm, ticking comfort of her xiaohao, the little Mao bell motionless above her, the couch a comfortable pressure beneath her, no sound but the soft hiss of static in the speakers pressed against her ear.
She closed her eyes.
And so the countdown reached its climax, as it had for Gagarin, Glenn and Armstrong before her.
Book One
LANDING
As the pilots prepared for the landing, Columbia’s flight deck took on the air of a little cave, Benacerraf thought, a cave glowing with the light of the crew’s fluorescent glareshields, and of Earth. Despite promises of upgrades, this wasn’t like a modern airliner, with its “glass” cockpit of computer displays. The battleship-gray walls were encrusted with switches and instruments that shone white and yellow with internal light, though the surfaces in which they were embedded were battered and scuffed with age. There was even an eight-ball attitude indicator, right in front of Tom Lamb, like something out of World War Two; and he had controls the Wright brothers would have recognized: pedals at his feet, a joystick between his legs.
