A slurry of sludge and chips blown back from the blades clumped and writhed over the Polyglas canopy, making it seem as if something out there was alive, but beyond the walls of the smooth-cut shaft there was nothing but dense ice.
“Don’t slow down,” Forster said, as if anticipating some uncharacteristic caution on Blake’s part. Forster tugged at his nose and muttered little ruminative wordless bleats, watching the image of the ice mole boring closer to the bright boundary of ice and water.
Forster was sure he knew what that thing in the middle of Amalthea was, although he hadn’t known a thing
about
it until they’d finally started getting the hard data a few days ago. Years had passed since his conviction had started him on the difficult path to these discoveries.
The view through the window was almost total black-ness, relieved only by reflected light from the cockpit in-struments; the view on their screen vividly depicted the mole grinding its way straight down through the ice. Behind it, liquified ice flashed into vapor and was propelled up the shaft. But to Forster’s imaginative eye, the deeper they got the more the surrounding ice seemed to glow with some faint and distant source of radiance.
Up on the flight deck of the
Ventris
, the same recon-structed graphic from the mole’s mapper was available on the big screens, alongside the projection of the
Ventris
’s more powerful and sophisticated seismic-tomography program. Here there was nothing uncertain—within the limit of resolution of sound waves in water—about the size and shape of Amalthea’s crust or the object at its core. On these screens were incorporated the dimensions, temperature, density, and reflectivity, at every depth, of multiple imagi-nary slices through the moon. Yet even on
Ventris
’s screens the core was represented as a black hole. For the core object was almost perfectly absorptive of sound waves.
The boiling hot water around it was pictured with perfect clarity, in false colors that showed the intricate eddies and jets surrounding the core. But no image of the inside of the core was possible; whatever it was made of either did not transmit ordinary vibration or somehow actively damped the vibrations of the seismic disturbance that buffeted it on every side.
Over Jo Walsh’s shoulder, Tony Groves watched in fas-cination as the mole descended. “Caution now, caution now.” His voice was almost a whisper.
Unfortunately live visuals were missing: the mole’s orig-inal designers had not thought it sensible to put a camera on a machine that was meant to spend its working life sur-rounded by solid ice. “Blake. Professor. Can you see anything? Tell us what you see,” Walsh said.
Lazy spirals of cable descended as slowly as smoke wreaths from the bulk of the
Michael Ventris
. Power cables and safety cables slithered across the ice toward the hole and disappeared into the vapor plume, following the mole inward. To Hawkins and McNeil, hovering nearby on the surface, the sign of the mole’s progress was a plume of ag-itated vapor in the mist.
They heard the reports from the mole over their suit-comms, and for a moment Hawkins shared the thrill of the impossible discovery.
Life
. For that moment, at least, he was able to stop thinking about Marianne Mitchell and Randolph Mays.
Even in the midst of his self-described insanity he re-tained his charm, however. Whether he had really read her so completely, or whether it was just wonderful luck, Mar-ianne found that he exerted a powerful attraction upon her. He was almost old enough to be her father—though not so old as her real father, which perhaps lowered that particular psychological barrier—and he was far from conventionally handsome. Nowhere near as handsome as . . . well, Bill Haw-kins, for example. But his . . .
rugged
look and, mm,
rangy
physique were kind of sexy if you thought about it, and his mind . . .
She loved working with him. She wouldn’t have minded something more than work. But he had treated her with nothing but professional courtesy. She did her best to live up to all his expectations in that category, and at first she trotted after him as faithfully as a pet. . . .
Marianne was not the only woman on Ganymede who was trying to read Randolph Mays’s mind. Sparta had hardly stopped thinking about him since Forster’s press conference, on the eve of the launch of the
Ventris
. She had never seen him in person before. So intrigued was she by the stagy presence of the historian-reporter, in fact, that she had de-cided not to be aboard the
Ventris
when it blasted for Amalthea.
He said nothing, only stared morosely at the wall. He was sitting on a sprung plastic-covered couch, legs stretched out and arms crossed, and she was pacing the scuffed tile floor of the visitors’ area in the Space Board’s headquarters on Ganymede, a grim, cramped room in a grim, bulging, pressure structure hidden from casual view among blast domes and fuel storage tanks in a remote corner of the spaceport— a structure whose low domed profile and win-dowless, government-gray skin were a reflection of the uneasy relations between the Space Board and the Indo-Asian communities of the Galilean moons.
The commander shifted uneasily on the broken springs of the steel-backed couch. “Why do you want to bother with Mays? He’s got no way of interfering with Forster now, no way of getting to Amalthea. We have him right where we want him, under observation.”
Ganymede had an electromagnetic cargo launcher like the two on Earth’s moon—proportionally longer, of course, some fifty kilometers overall, to accommodate Ganymede’s greater gravity. In addition to freight services and routine transportation to parking orbit, the Ganymede launcher of-fered something Earth’s moon couldn’t—self-guided tours of Jupiter’s spectacular Galilean moons.
But the delta-vees required to send even an essentially free-falling capsule around the Jovian system and get it back again didn’t come cheap, and selling tour tickets at several hundred new dollars a pop wasn’t a cinch. Over the years the hucksters had evolved a graduated pitch:
Free!
—and available at any of the numerous agencies with offices on the main square—was an informational slide show, a minichip’s load of two-and-a-half-dimensional views of the Galilean moons as seen through the portholes of automated tour cruisers, with an accompanying narration consisting mostly of astronomical facts—cleverly presented by leading industrial psychologists to instill in the viewer the conviction that there was something interesting out there, and whatever it was wouldn’t be learned from
this
feeble presentation.
For only a few new cents more, one could view a three--dee-feelie in the big Ultimax theater, just off the Shri Yantra square. Breathtaking fly-bys of Callisto, Ganymede, Europa, Io! See Grooved and Twisted Terrain! See History in the Craters! See the Largest Active Volcano in the Solar System! Outside the theater, buy sackfuls of Greasy Dim Sum and Fried Won Ton!
And for just one new dollar more, you could ride Captain Io’s Mystery Tour, which mimicked a close pass right through the plume of Io’s biggest sulfur eruption. The tilt-ing, vibrating seats, the high-speed, high-definition images, the screaming music and sound effects made a thrilling ride for adults and even for very young children.
Randolph Mays and Marianne Mitchell were led through the boarding stages of the Rising Moon Enterprises tour by brightly uniformed young men and women who all seemed to have been cloned from the same pair of traditionally golden-haired Southern Californians—Ken ’n’ Barbies who might have seemed strangely out of place in this Asian cul-ture, were it not for the ancient Disneyland tradition, much admired in Earth’s Mysterious East. If any thoughts lurked behind these white-toothed, blue-eyed smiles, the customer would never know it; these kids were paid to stay
cheerful
.
Marianne was too shrewd not to see the boredom and alarm that alternately lurked just beneath the smiling faces, and it made her uneasy. But unless she was willing to make a scene it was too late, for suddenly she and Mays were left alone, strapped into the cramped cabin of Moon Cruiser Number Four, lying side by side in standard suits that stank of a thousand users before them. They faced a videoplate screen wide enough to virtually fill the field of view. The console below it was so simple it looked fake. There were no instruments on this ship except those needed to monitor volume and frequency, no controls except those needed to change channels and adjust sound and picture quality.
At the moment, the wide screen videoplate was display-ing the view from the capsule of the launcher’s marshalling yard. It was about as attractive as a subway station in mid-20th-century Boston. “Somehow this wasn’t how I pictured the business of interplanetary investigative reporting, Randolph,” said Mar-ianne. Her thin voice through the commlink sounded weary, on the verge of discouragement.
“No one could
possibly
understand the back ground of the events on Amalthea without a first hand
look
at the Jovian system,” Mays replied. For all the effort in his deliv-ery, he didn’t sound completely convincing.
The capsule lurched violently, and he was saved from the necessity of a reply. Somewhere machinery had begun to hum, jostling their capsule forward onto magnetic tracks. They were moving through the switchyard to join a string of other capsules, lined up for launch. Most carried cargo destined for transfer to ships in orbit, while others were going up empty, for more cargo came down to the surface of Ganymede than left it. Perhaps once a week, a couple of Moon Cruisers held tourists like themselves.
The image on the videoplate showed the capsule nearing the end of the electromagnetic cannon that would shortly fire them into space. Except for entertainment programs prerecorded on chip, only one other view could be accessed by the passengers, and that was a schematic of the planned trajectory.
Tour itineraries varied constantly with the positions of the Galilean moons. Often no tours were possible, especially when Io was inaccessible, for Io, with its Technicolor land-scape and its sulfur plumes a hundred kilometers high, was the moon tourists really wanted to see.
