When she saw him she was pleased that he had come, but irritated that he had come so late. It was almost time for her to go. Up the cable, onto a shuttle, out to one of the new hollowed-out asteroids, this one particularly large and luxuriant; and then off, accelerating for a matter of months, until it could coast at several percent of the speed of light. For this asteroid was a starship; and they were off to a star near Aldebaran, where a Mars-like planet rolled in an Earth-like orbit around a sun-like sun. A new world, a new life. And Jackie was going.

Nirgal still couldn’t quite believe it. He had gotten the message only two days before, had not slept as he tried to decide whether this mattered, whether it was part of his life, whether he ought to see her off, whether he ought to try to talk her out of it.

Seeing her now, he knew he could not talk her out of it. She was going. I want to try something new, she had said in her message, a voice record without a visual image. There coming from his wrist, her voice: There’s nothing for me here now anymore. I’ve done my part. I want to try something new.

The group in the starship asteroid were mostly from Dorsa Brevia. Nirgal had called Charlotte to try to find out why. It’s complicated, Charlotte said. There’s a lot of reasons. This planet they’re going to is relatively nearby, and it’s perfect for terraforming. Humanity going there is a big step. The first step to the stars.

I know, Nirgal had said. Quite a few starships had already left, off to other likely planets. The step had been taken.

But this planet is the best one yet. And in Dorsa Brevia, people are beginning to wonder if we don’t have to get that distance from Earth to get a fresh start. The hardest part is leaving Earth behind. And now it’s looking bad again. These unauthorized landings; it could be the start of an invasion. And if you think of Mars as being the new democratic society, and Earth the old feudalism, then the influx can look like the old trying to crush the new, before it gets too big. And they’ve got us outnumbered twenty billion to two. And part of that old feudalism is patriarchy itself. So the people in Dorsa Brevia wonder if they can get a little bit more distance. It’s only twenty years to Aldebaran, and they’re going to live a long time. So a group of them are doing it. Families, family groups, childless couples, childless single people. It’s like the First Hundred going to Mars, like the days of Boone and Chalmers.

And so Jackie sat on the carpeted floor of the departure lounge, and Nirgal sat next to her. She looked down. She was smoothing the carpet with the palm of her hand, and then drawing patterns in the nap, letters. Nirgal, she wrote.

He sat down beside her. The departure lounge was crowded but subdued. People looked grave, wan, upset, thoughtful, radiant. Some were going, some were seeing people off. Through a broad window they looked into the interior of the socket, where elevator cars levitated in silence against the walls, and the foot of the 37,000-kilometer-long cable stood hovering ten meters over the concrete floor.

So you’re going, Nirgal said.

Yes, Jackie said. I want a new start.

Nirgal said nothing.

It will be an adventure, she said.

True. He didn’t know what else to say.

In the carpet she wrote Jackie Boone Went to the Moon.

It’s an awesome idea when you think of it, she said. Humanity, spreading through the galaxy. Star by star, ever outward. It’s our destiny. It’s what we ought to be doing. In fact I’ve heard people say that that’s where Hiroko is— that she and her people joined one of the first starships, the one to Barnard’s star. To start a new world. Spread viriditas.

It’s as likely as any other story, Nirgal said. And it was true; he could imagine Hiroko doing it, taking off again, joining the new diaspora, of humanity across the stars, settling the nearby planets and then on from there. A step out of the cradle. The end of prehistory.

He stared at her profile as she drew patterns on the carpet. This was the last time he would ever see her. For each of them it was as if the other were dying. That was true for a lot of the couples huddled silently together in this room. That people should leave everyone they knew.

And that was the First Hundred. That was why they had all been so strange— they had been willing to leave the people they knew, and go off with ninety-nine strangers. Some of them had been famous scientists, all of them had had parents, presumably. But none of them had had children. And none of them had had spouses, except for the six married couples who had been part of the hundred. Single childless people, middle-aged, ready for a fresh start. That was who they were. And now that was Jackie too: childless, single.

Nirgal looked away, looked back; there she was, flush in the light. Fine-grained gloss of black hair. She glanced up at him, looked back down. Wherever you go, she wrote, there you are.

She looked up at him. What do you think happened to us? she asked.

I don’t know.

They sat looking at the carpet. Through the window, in the cable chamber, an elevator levitated across the floor, hovering upright as it moved over a piste to the cable. It latched on, and a jetway snaked out and enveloped its outer side.

Don’t go, he wanted to say. Don’t go. Don’t leave this world forever. Don’t leave me. Remember the time the Sufis married us? Remember the time we made love by the heat of a volcano? Remember Zygote?

He said nothing. She remembered.

I don’t know.

He reached down and rubbed the nap of the carpet so that he erased the second you. With his forefinger he wrote we.

She smiled wistfully. Against all the years, what was a word?

The loudspeakers announced that the elevator was ready for departure. People stood, saying things in agitated voices. Nirgal found himself standing, facing Jackie. She was looking right at him. He hugged her. That was her body in his arms, as real as rock. Her hair in his nostrils. He breathed in, held his breath. Let her go. She walked off without a word. At the entry to the jetway she looked back once; her face. And then she was gone.

Later he got a print message by radio from deep space. Wherever you go, there we are. It wasn’t true. But it made him feel better. That was what words could do. Okay, he said as he went through his days wandering the planet. Now I am flying to Aldebaran.
