Thirty-six thousand kilometers ahead, Earth gleamed at half phase—with dawn breaking across eastern North America, while the Atlantic, Europe, and Africa lay in full light between swirls and shreds of brilliant white cloud. At this distance, the planet spread across just 20 degrees of arc pole to pole, appearing delicate and impossibly fragile.
More fragile still, though, was the web of orbital structures just ahead in America’s path. SupraQuito hung suspended on the slender tether of its elevator cable in synch-orbit, directly above Earth’s equator some 35,783 kilometers above the top of the mountain to which it was anchored. The structure—or interconnected series of structures, actually—was an enormous collection of hab modules, shipyards, orbital factories, environmental facilities, power plants and collectors, agro spheres, and docking facilities suspended between the elevator dropping to Earth, and the support tether leading up to the anchor some thirty thousand kilometers farther out.
From here, SupraQuito—including the tangle of structures that housed the Earth Confederation government—was visible, barely, as a thread-slender gleam of reflected sunlight, with constellations of tiny stars showing in the shadows. Some day, a thousand years hence, perhaps, SupraQuito would join with the other two space elevators, at Singapore and at Tanganyika, and become a true, inhabited ring encircling the Earth. At the moment, the entire massive structure appeared gossamer and delicate, far too insubstantial to trap the oncoming bulk of the Star Carrier America.
America herself was at the helm. The powerful AI residing within the carrier’s electronic network possessed far more memory and processing power—by several orders of magnitude—than did a merely human brain. Exact comparisons between the relative brainpower of man and machine were meaningless, however, and probably impossible to calculate in any case. America’s mind, if that was the proper term, was wholly focused on the ship, its systems, its functioning, its navigation and control. At the moment, she was judging the remaining distance between her prow and Docking Tube One at the SupraQuito Military Fleet Base now just a few hundred kilometers ahead, and her own rate of deceleration. With a closing velocity of 8.64 kilometers per second, she needed to increase the gravitational mass currently being projected dead astern by 37 percent in three … two … one … now.
America kept up a running dialogue with her counterpart at Fleet Base Approach Control, with every aspect of her vector checked hundreds of times each passing second. The docking facility was not stationary, of course. Its omega, its angular velocity, kept it precisely above its attachment point in the Andes Mountains of Ecuador. At synchronous orbit, this worked out to 3.0476 kilometers per second.
For ten long seconds, America decelerated. With the ship enmeshed within the gravitational field of the projected singularity aft, the deceleration was unfelt by the vessel’s passengers and crew. For them, the slowly rotating hab rings provided spin gravity. America slowed … slowed …
A final, precisely timed nudge from singularities to starboard gave her the necessary 3.0476 kps lateral velocity.
And with perfect choreography the massive carrier dropped into the sweet spot just five kilometers off the docking port, all singularities winking out before they could warp the delicate structure of the base. Grappling tethers, extended along the carrier’s length, reached toward the dock. America would be warped into her berthing space—an ancient seafaring term that had nothing to do with her space-bending Alcubierre faster-than-light drives. The tethers connected with grappling points along the berthing area and began to contract. A small fleet of powerful little tugs emerged from the base, taking up station and nudging the carrier toward the dock. Slowly, very slowly, the quarter-million-ton carrier was hauled into port.
While America’s AI was far more powerful in most respects than human intelligence, the ship possessed nothing like human emotion. She heard the cheers from personnel on her bridge and in her CIC, from lounge decks and ready rooms and flight decks where members of her crew had gathered to watch the docking. Most of them, evidently, were delighted to be home, though the carrier had only an academic understanding of what that might mean. America had been on extended patrol for the past six weeks, watching for evidence of further incursions by the enemy Turusch. Her admiral had been ordered home to attend a ritual that America did not understand at all, even in theory.
The tether cables continued to contract and the dockyard tugs continued to nudge, drawing the ship closer and closer to her berth. Braces gently swung out to arrest that movement with a jar barely felt by the humans on board. Magnetic clamps snapped home, and the debarkation tube extended from the berthing module to America’s quarterdeck, located in zero-G at her central spine, immediately abaft the shield cap and just forward of the still rotating hab modules.
“All hands, this is the Captain.” The voice was that of Captain Randolph Buchanan, America’s commanding officer. “Welcome home!”
But for the Star Carrier America, this certainly was not home.
This was a temporary waypoint, a momentary interruption of her duties, of her electronic life.
For America, home was always … out there.

“Why in a quantum-warped hell do I have to go to this thing?” Rear Admiral Alexander Koenig glared at his own image projected on the wall screen in his quarters.
“Your adoring public, of course,” a voice replied in his head. “They want to see you, shake your hand, and give you the worship due a conquering hero.”
“Bullshit,” Koenig growled. “I think it’s just more politics, and the sooner I’m back on America’s flag deck the better, so far as I’m concerned.”
“Harsh words from the man who saved Earth.”
He winced a bit at that. He’d saved Earth, yes, in what was now being called the Defense of Earth, a rare and hard-won naval victory just two months ago. But there’d been losses … terrible losses. And one of them …
“Let me see you, Karyn,” he said.
The room’s electronics projected a holographic image into the suite’s sunken living area, a smiling woman Koenig’s age in the black-and-gray dress uniform of a Confederation Navy rear admiral. She looked … perfect, exactly as he remembered her.
Exactly as she’d been before the high-velocity Turusch impactor had slashed through the military synchorbital base above Mars known as Phobia, wrecking Mars Fleet CIC, the fleet dockyard, and killing thousands of civilian, Marine, and Navy personnel … including Karyn Mendelson.
He’d recovered her PA, her personal assistant. Copies had resided within his own communications implants, and in his office on board the Star Carrier America, and elsewhere. When she’d been alive, it had been able to project an AI simulacrum, an avatar, of Karyn indistinguishable from the living person over any communications or virtual net links. PAs could project the owner’s image to field the flood of routine requests and calls received every day. Such avatars were smart enough to hold conversations and even make routine decisions for the original.
They weren’t the same, though, weren’t as responsive or as smart, and most important, they weren’t flesh and blood.
God, he missed her.
The image in front of him looked a
