I was sober enough to thank her for trying to sober me up.

"I needed to get away, too," she said. "All those people E.D. invited. None of them knew your mother in any important way. Not one. They're in there talking about appropriations bills or payload tonnage. Making deals."

"Maybe it's E.D.'s way of paying tribute to her. Salting the wake with political celebrities."

"That's a generous way of interpreting it."

"He still makes you angry." So easily, I thought.

"E.D.? Of course he does. Though it would be more charitable to forgive him. Which you seem to have done."

"I have less to forgive him for," I said. "He's not my father."

I didn't mean anything by it. But I was still too aware of what Jason had told me a few weeks ago. I choked on the remark, reconsidered it even before the sentence was out of my mouth, blushed when I finished. Diane gave me a long uncomprehending look; then her eyes widened in an expression that mingled anger and embarrassment so plainly that I could parse it even by the dim glow of the porch light.

"You've been talking to Jason," she said coldly.

"I'm sorry—"

"How does that work exactly? Do the two of you sit around making fun of me?"

"Of course not. He—anything Jason said, it was because of the medication."

Another grotesque faux pas, and she pounced on it: "What medication?"

"I'm his GP. Sometimes I write him prescriptions. Does it matter?"

"What medication makes you break a promise, Tyler? He promised he would never tell you—" She drew another inference. "Is Jason sick! Is that why he didn't come to the funeral?"

"He's busy. We're just days away from the first launches."

"But you're treating him for something."

"I can't ethically discuss Jason's medical history," I said, knowing this would only inflame her suspicions, that I had essentially given away his secret in the act of keeping it.

"It would be just like him to get sick and not tell any of us. He's so, so hermetically sealed.…"

"Maybe you should take the initiative. Call him sometime."

"You think I don't? Did he tell you that, too? I used to call him every week. But he would just turn on that blank charm and refuse to say anything meaningful. How are you, I'm fine, what's new, nothing. He doesn't want to hear from me, Tyler. He's deep in E.D.'s camp. I'm an embarrassment to him." She paused. "Unless that's changed."

"I don't know what's changed. But maybe you should see him, talk to him face to face."

"How would I do that?"

I shrugged. "Take another week off. Fly back with me."

"You said he's busy."

"Once the launches begin it's all sit back and wait. You can come to Canaveral with us. See history being made."

"The launches are futile," she said, but it sounded like something she had been taught to say; she added, "I'd like to, but I can't afford it. Simon and I do all right. But we're not rich. We're not Lawtons."

"I'll spot you the plane fare."

"You're a generous drunk."

"I mean it."

"Thank you, but no," she said. "I couldn't."

"Think about it."

"Ask me when you're sober." She added, as we mounted the steps to the porch, yellow light hooding her eyes, "Whatever I might once have believed—whatever I might have told Jason—"

"You don't have to say this, Diane."

"I know E.D. isn't your father."

What was interesting about her disclaimer was the way she delivered it. Firmly, decisively. As if she knew better now. As if she had discovered a different truth, an alternative key to the Lawton mysteries.

Diane went back to the Big House. I decided I couldn't face more well-wishing. I let myself into my mother's house, which seemed airless and overheated.

Carol, the next day, told me I could take my time about cleaning out my mother's things, which she called "making arrangements." The Little House wasn't going anywhere, she said. Take a month. Take a year. I could "make arrangements" whenever I had the time and as soon as I felt comfortable with it.

Comfort wasn't even on the horizon, but I thanked her for her patience and spent the day packing for the flight back to Orlando. I was nagged by the idea that I ought to take something of my mother's with me, that she would have wanted me to keep a memento for some shoebox of my own. But what? One of her Hummel figurines, which she had loved but which had always struck me as expensive kitsch? The cross-stitched butterfly from the living room wall, the print of Water Lilies in a do-it-yourself frame?

Diane showed up at the door while I was debating. "Does that offer still stand? The trip to Florida? Were you serious about that?"

"Of course I was."

"Because I talked to Simon. He's not completely delighted with the idea, but he thinks he'll be okay on his own for a few more days."

Mighty considerate of him, I thought.

"So," she said, "unless—I mean, I know you'd been drinking—"

"Don't be silly. I'll call the airline."

I booked a seat in Diane's name on the next day's first D.C/Orlando junket.

Then I finished packing. Of my mother's things, I settled at last on the pair of chipped jade Buddha bookends.

I looked around the house, even checked under the beds, but the missing mementos (school) seemed to have vanished permanently.

SNAPSHOTS OF THE ECOPOIESIS

Jason suggested we take rooms in Cocoa Beach and wait a day for him to join us there. He was doing a last round of media Q & A at Perihelion but had cleared his schedule prior to the launches, which he wanted to witness without a CNN crew dunning him with boneheaded questions.

"Great," Diane said when I relayed this information. "I can ask all the boneheaded questions myself."

I had managed to calm her fears about Jason's medical condition: no, he wasn't dying, and any temporary blips on his medical record were his own business. She accepted that, or seemed to, but still wanted to see him, if only to reassure herself, as if my mother's death had shaken her faith in the fixed stars of the Lawton universe.

So I used my Perihelion ID and my connection with Jase to rent us two neighboring suites in a Holiday Inn with a view toward Canaveral. Not long after the Mars project was conceived—once the EPA's objections had been noted and ignored—a dozen shallow-water launch platforms had been constructed and anchored off the coast of Merritt Island. It was these structures we could see most clearly from the hotel. The rest of the view was parking lots, winter beaches, blue water.

We stood on the balcony of her suite. She had showered and changed after the drive from Orlando and we were about to go down and brave the lobby restaurant. Every other balcony we could see bristled with cameras and lenses: the Holiday Inn was a designated media hotel. (Simon may have distrusted the secular press but Diane was suddenly knee-deep in it.) We couldn't see the setting sun but its light caught the distant gantries and rockets and rendered them more ethereal than real, a squadron of giant robots marching off to some battle in the Mid-Atlantic Trench. Diane stood back from the balcony railing as if she found the view frightening. "Why are there so many of them?"

"Shotgun ecopoiesis," I said.

She laughed, a little reproachfully. "Is that one of Jason's words?"

It wasn't, not entirely. "Ecopoiesis" was a word coined by a man named Robert Haynes in 1990, back when terraforming was a purely speculative science. Technically it meant the creation of a self-regulating anaerobic biosphere where none had existed before, but in modern usage it referred to any purely biological modification of Mars. The greening of Mars required two different kinds of planetary engineering: crude terraforming, to raise the surface temperature and atmospheric pressure to a plausible threshold for life, and ecopoiesis: using microbial and plant life to condition the soil and oxygenate the air.
