Den Simmons - Orphans of the Helix

The great spinship translated down from Hawking space into the red-and-white double light of a close binary. While the 684,300 people of the Amoiete Spectrum Helix dreamt on in deep cryogenic sleep, the five AIs in charge of the ship conferred. They had encountered an unusual phenomenon and while four of the five had agreed it important enough to bring the huge spinship out of C-plus Hawking space, there was a lively debatecontinuing for several microsecondsabout what to do next.

The spinship itself looked beautiful in the distant light of the two stars, white and red light bathing its kilometer-long skin, the starlight flashing on the three thousand environmental deep-sleep pods, the groups of thirty pods on each of the one hundred spin hubs spinning past so quickly that the swing arms were like the blur of great, overlapping fan blades, while the three thousand pods themselves appeared to be a single, flashing gem blazing with red and white light. The Aeneans had adapted the ship so that the hubs of the spinwheels along the long, central shaft of the ship were slantedthe first thirty spin arms angled back, the second hub angling its longer thirty-pod arms forward, so that the deep-sleep pods themselves passed between each other with only microseconds of separation, coalescing into a solid blur that made the ship under full spin resemble exactly what its name impliedHelix. An observer watching from some hundreds of kilometers away would see what looked to be a rotating human double DNA helix catching the light from the paired suns.

All five of the AIs decided that it would be best to call in the spin pods. First the great hubs changed their orientation until the gleaming helix became a series of three thousand slowing carbon-carbon spin arms, each with an ovoid pod visible at its tip through the slowing blur of speed. Then the pod arms stopped and retracted against the long ship, each deep-sleep pod fitting into a concave nesting cusp in the hull like an egg being set carefully into a container.

The Helix, no longer resembling its name now so much as a long, slender arrow with command centers at the bulbous, triangular head, and the Hawking drive and larger fusion engines bulking at the stern, morphed eight layers of covering over the nested spin arms and pods. All of the AIs voted to decelerate toward the G8 white star under a conservative four hundred gravities and to extend the containment field to class twenty. There was no visible threat in either system of the binary, but the red giant in the more distant system wasas it should beexpelling vast amounts of dust and stellar debris. The AI who took the greatest pride in its navigational skills and caution warned that the entry trajectory toward the G8 star should steer very clear of the L1 Roche lobe point because of the massive heliosphere shock waves there, and all five AIs began charting a deceleration course into the G8 system that would avoid the worst of the heliosphere turmoil. The radiation shock waves there could be dealt with easily using even a class-three containment field, but with 684,300 human souls aboard and under their care, none of the AIs would take the slightest chance.

Their next decision was unanimous and inevitable. Given the reason for the deviation and deceleration into the G8 system, they would have to awaken humans. Saigy, AI in charge of personnel lists, duty rosters, psychology profiles, and who had made it its business to meet and know each of the 684,300 men, women, and children, took several seconds to review the list before deciding on the nine people to awaken.

Dem Lia awoke with none of the dull hangover feel of the old-fashioned cryogenic fugue units. She felt rested and fit as she sat up in her deep-sleep crche, the unit arm offering her the traditional glass of orange juice.

Emergency? she said, her voice no more thick or dull than it would have been after a good nights sleep.

Nothing threatening the ship or the mission, said Saigy, the AI. An anomaly of interest. An old radio transmission from a system which may be a possible source of resupply. There are no problems whatsoever with ship function or life support. Everyone is well. The ship is in no danger.

How far are we from the last system we checked? said Dem Lia, finishing her orange juice and donning her shipsuit with its emerald green stripe on the left arm and turban. Her people had traditionally worn desert robes, each robe the color of the Amoiete Spectrum that the different families had chosen to honor, but robes were impractical for spinship travel where zero g was a frequent environment.

Six thousand three hundred light-years, said Saigy.

Dem Lia stopped herself from blinking. How many years since last awakening? she said softly. How many years total voyage ship time? How many years total voyage time-debt?

Nine ship years and one hundred two time-debt years since last awakening, said Saigy. Total voyage ship time, thirty-six years. Total voyage time-debt relative to human space, four hundred and one years, three months, one week, five days.

Dem Lia rubbed her neck. How many of us are you awakening?

Nine.

Dem Lia nodded, quit wasting time chatting with the AI, glanced around only once at the two-hundred-some sealed sarcophagi where her family and friends continued sleeping, and took the main shipline people mover to the command deck, where the other eight would be gathering.

The Aeneans had followed the Amoiete Spectrum Helix peoples request to construct the command deck like the bridge of an ancient torchship or some Old Earth, pre-Hegira seagoing vessel. The deck was oriented one direction to down and Dem Lia was pleased to notice on the ride to the command deck that the ships containment field held at a steady one gee. The bridge itself was about twenty-five meters across and held command-nexus stations for the various specialists, as well as a central tableround, of coursewhere the awakened were gathering, sipping coffee and making the usual soft jokes about cryogenic deep-sleep dreams. All around the great hemisphere of the command deck, broad windows opened onto space: Dem Lia stood a minute looking at the strange arrangement of the stars, the view back along the seemingly infinite length of the Helix itself where heavy filters dimmed the brilliance of the fusion-flame tail that now reached back eight kilometers toward their destinationand the binary system itself, one small white star and one red giant, both clearly visible. The windows were not actual windows, of course; their holo pickups could be changed and zoomed or opaqued in an instant, but for now the illusion was perfect.

Dem Lia turned her attention to the eight people at the table. She had met all of them during the two years of ship training with the Aeneans, but knew none of these individuals well. All had been in the select group of fewer than a thousand chosen for possible awakening during transit. She checked their color-band stripes as they made introductions over coffee.

Four men, five women. One of the other women was also an emerald green, which meant that Dem Lia did not know if command would fall to her or the younger woman. Of course, consensus would determine that at any rate, but since the emerald green band of the Amoiete Spectrum Helix poem and society stood for resonance with nature, ability to command, comfort with technology, and the preservation of endangered life-formsand all 684,300 of the Amoiete refugees could be considered endangered life-forms this far from human spaceit was assumed that in unusual awakenings the greens would be voted into overall command.

In addition to the other greena young, redheaded woman named Res Sandrethere was: a red-band male, Patek Georg Dem Mio; a young, white-band female named Den Soa whom Dem Lia knew from the diplomacy simulations; an ebony-band male named Jon Mikail Dem Alem; an older yellow-band woman named Oam Rai whom Dem Lia remembered as having excelled at ship systems operations; a white-haired blue-band male named Peter Delen Dem Tae whose primary training would be in psychology; an attractive female violet-bandalmost surely chosen for astronomynamed Kem Loi; and an orange maletheir medic, whom Dem Lia had spoken to on several occasionsSamel Ria Kem Ali, known to everyone as Dr. Sam.
