C-in-C Space Command, a four-star Air Space Force general, took the stand before them. He glared at them with hands on hips and addressed them through a booming PA: The USASF’s proudest moment since we took command of the high frontier on the occasion of our sixtieth anniversary in 2007… The finest candidates from all the services… a rigorous selection process… the first U.S. spaceborne troops…

The fifty of them were dressed in their space suits: bright silver with service epaulettes and name patches, white helmets under their arms, gloves neatly folded. Why the hell the suits should be silver she didn’t know — she looked like a cross between John Glenn and Buck Rogers — but she had to concede they looked magnificent, shining in the California sun, and maybe that was the point. TV cameras hovered around them, beaming their smiling faces across the planet. Symbols, she thought. But that made her feel good, to be a symbol of strength and reassurance in these difficult times. She stood a little taller.

And now there was action at the launch facility itself. One of the assembly structures started to roll back.

… From the major conflicts of history we learn conclusive lessons: the Trojan Horse. Hannibal’s crossing of the Alps. The retreat of Napoleon s infantry from Moscow. All of these underscore the strategic necessity for effective transportation of troops and their support equipment. Each new era of human progress has brought with it an urgency for an expanded military transport capability, most recently to global ranges, and now to the truly interplanetary scale…

A spacecraft was revealed.

It was a blunt cylinder. It was capped by a truncated, rounded nose cone, and fat auxiliary cylinders — expendable fuel tanks? — were strapped to the hull. She looked at the base, searching for rocket nozzles, but she saw only a broad dish shape, like a pie dish. The hull was coated with what looked like space shuttle thermal blankets and tiles, black and white, and there were big USASF decals and lettering. TV camera drones buzzed around the walls like flies.

This new vessel is over two hundred feet tall, taller than the space shuttle, with a base diameter of eighty feet and a gross weight of fourteen million pounds. We have thirty-six combustion chambers and eighteen turbo pumps; the fuel system is liquid hydrogen and oxygen. The rocket engines are the most advanced available, developed by Lockheed Martin for the Ven-tureStar. They are based on the “aerospike “ principle, which I am assured will ensure optimal operation at all altitudes, from ground to interplanetary space. . .

The bird looked like a toy, gleaming in the sun. She couldn’t see how it could be big enough to lift all of them to orbit, let alone all the way to an asteroid.

It was only when she saw a technician walking past — an orange-hatted insect — that she got a sense of the ship’s true scale.

It was immense.

… We call her Bucephalus. She is the outcome of a whole series of covert projects mounted since we were effectively grounded by the Challenger debacle. She is built on studies developed over decades, but she has been designed, tested, constructed in a couple of months. This is U.S. can-do at its best, rising to this new challenge. Bucephalus will develop a takeoff thrust of eighteen million pounds, which is two and a half times as much as the Saturn rocket that took us to the Moon, and it will be so damn loud our major problem will be preventing it shaking Vandenberg to pieces…

Laughter at that. Nervous, but laughter.

Ladies and gentlemen, she is named after Alexander the Great’s charger. Now she is your steed. Ride her now into the great out there, ride her to victory beyond the sky itself!

They cheered, of course. They even threw their white space helmets into the air. You had to make the four-star feel good about his project.

But June knew she wasn’t the only one who gazed down on the giant fat ship — scrambled together in just months and now destined to hurl them all off the planet — with deep, stomach-churning dismay.

Reid Malenfant:

The night before they reached the asteroid, Malenfant had

trouble sleeping.

Every time he turned over he would float up out of his bunk, or find his face in the breeze of the air-conditioning vent. When he took off his eye shield and earplugs the noise of the air system’s mechanical rattling broke over him, and the dimmed lights of the meatware deck leaked around the curtain into his compartment.

He dozed a little, woke up alone, one more time. He decided to pop a pill. He climbed out of his bunk and made for the galley.

There was movement far overhead. It was Emma, visible through the mesh ceiling.

For a heartbeat he was shocked to find her there, as if he’d forgotten she was here on the ship. He had to think back, to remember how he’d coerced her onto the ship at the Mojave.

She was up on the zero G deck. She seemed to be spinning in the air, as if she were performing somersaults.

He pulled himself up the ladder and joined her. When he arrived she stopped, looking sheepish. She was wearing a loose cotton coverall.

He whispered, “What’s up?”

“Just trying to see Earth.”

He looked out the window. There were Earth and Moon, neatly framed, a blue pebble and its wizened rocky companion, still the brightest objects in the sky save for the sun itself. They were spinning, of course, wheeling like the stars behind them, four times a minute.

“You know,” she said, “it’s funny. Every time I wake up I’m surprised to find myself here. In this ship, in space. In my dreams I’m at home, I think.”

“Let me try.” He braced himself on the struts behind her. He took her waist. He took his guide from Earth, the Moon turning around it like a clock hand, and soon he had her turning in synch. She stretched out her arms and legs, trying to keep herself stable. Her hair, which she was growing out, billowed behind her head like a flag, brushing his face when it passed him. When she slowed, he was able to restore her motion with a brushing stroke of her bare arm or leg. She laughed as he spun her, like a kid.

Her skin was soft, warm, smooth, full of water and life in this dusty emptiness.

He wasn’t sure how it happened, who initiated what. It did take a certain amount of ingenuity, however. The key, Malenfant discovered, was to brace himself against a strut for leverage.

Afterward she clung to him, breathing hard, her face moist with sweat against his chest, their nightclothes drifting in a tangled cloud around them.

“Welcome to the Three Dolphins Club,” he whispered.

“Huh?”

“How to have sex in free fall. If you can’t brace against anything, you do it like the dolphins do. You need a third person to push.”

She snorted laughter. “How do you knovil… Never mind. This was stupid.”

“We’re a long way from home, Emma. All we have out here—”

“Is each other. I know.” She stroked his chest. “Your skin is hard, Malenfant. That time in the desert toned you up. I think I can still smell it on you. Dry heat, like a sauna. You smell like the desert, Malenfant… I still don’t understand why you wanted me on this flight. I have a feeling you planned this whole damn thing from the beginning.”

Warm in his arms, she was waiting for an answer.

He said, “You have things I don’t, Emma. Things I need.”

“Like what?”

“A moral center.” *

“Oh, bullshit.”

“Really.” He waved a hand. “Remember the note left by that crazy, Art Morris, the guy who tried to shoot down the BOB. Look what you did, Malenfant.”

“He was crazy. You didn’t hurt his kid.”

“I know. But I have hurt a lot of people, to get us here. For example they probably threw poor George in jail. Look what I did. I think it’s worth it, all of this. I think it’s justified. But I don’t know” He studied her. “I need you to tell me, Emma. To guide me.”
