Drive

6

They had been married for six years when Solomon took the money he’d saved from his performances and efficiency bonuses and bought himself a yacht. It wasn’t a large ship; the living space in it was smaller than his first hole. It was almost five years old, and was going to require a month in the orbital shipyard docks before very much longer. The interior color scheme—cream and orange—wasn’t to his tastes. It had been sitting in dry dock for eight and a half months since its previous owner—a junior vice president of a Luna-based conglomerate—had died. His family on Luna didn’t have any plans to come to Mars, and the bother of retrieving it across the months-deep void made it easier for them to price it low and sell. For most people on Mars, a boat like that was an ostentatious status symbol and nothing more. There was no settled moon or inhabited L5 station to travel between. The trip to Earth in it would have been neither comfortable nor particularly safe. It could go around in orbit. It could run out into the vacuum near Mars, and then come back. That was about it, and the pointlessness of the exercise helped drive down the price ever farther. As a statement of wealth, it said its owner had had too much. As a means of transport, it was like having a race car that could never leave its track.

For Solomon, it was the perfect test vehicle.

The yacht had been designed around an engine he knew, and the build code was one he’d helped to write. When he looked at the technical and maintenance history, he could see every control array, every air recycling vent and cover. Before he’d even set foot on it, he knew it as well as he knew anything. Some parts of the exhaust system were things he’d designed himself a decade before. And, since he held the title to it, half a year’s worth of red tape would simply go away if he wanted to use it to test a some new refinements to the engines. That idea alone could make him cackle with delight.

No more permissions committees. No more hard capital liability reports. Just the boat, its reactor, a couple EVA suits and a set of industrial waldoes he’d had since he was in school. In previous eras, a scientist might have a garage PCR machine or a shed in the back of the house with beehives or disassembled engines or half-built prototypes of inventions that would change the world if they could just be made to work. Solomon had his yacht, and getting it was the most self-indulgent, delightful, important thing he’d done since the day he’d asked Caitlin to marry him.

And yet, even as the fertile garden of his mind sent up a thousand different green shoots of ideas and projects, tests and tweaks and adjustments, he found himself dreading the part where he told his wife what he’d done. And when the time came, his unease was justified.

“Oh, Sol. Oh, baby.”

“I didn’t spend my salary on it,” he said. “It was all bonus money. And it was only mine. I didn’t use ours.”

Caitlin was sitting on the bench in their multipurpose room, tapping her mouth with the tips of her fingers the way she did when she was thinking hard. The system was playing a gentle ambient music that was all soft percussion and strings loud enough to cover the hiss of the air recyclers but not so much as to overwhelm the conversation. As with almost all the new buildings on Mars, it was larger, better appointed, and deeper underground.

“So what I just heard you say is you can spend as much money out of the account as you want without talking to me if the total you pull is less than whatever you’ve made in bonuses. Is that what you meant?”

“No,” he said, though it was pretty close. “I’m saying that it wasn’t money we were counting on. All our obligations are covered. We’re not going to try to buy food and have the accounts come up empty. We’re not going to have to work extra hours or take on side jobs.”

“All right.”

“And this is important work. The design I have for the magnetic coil exhaust can really increase drive efficiency, if I can get—”

“All right,” she said.

He leaned against the door frame. The strings rose in a delicate arpeggio.

“You’re angry.”

“No, sweetie. I’m not angry,” she said gently. “Angry is yelling. This is resentful, and it’s because you’re cutting me out from the fun parts. Really, I look at you, and see the happiness and the excitement, and I want to be part of that. I want to jump up and down and wave my arms and talk about how great it all is. But that money was our safety net. You’re ignoring the fact that you spent our safety net, and if we both ignore it, the first time something unexpected comes up, we’re screwed. I love our life, so now I have to be the one who cares and disapproves and doesn’t get to be excited. You’re making me the grown-up. I don’t want to be the grown-up. I want us both to be grown-ups, so that when we do something like this, we both get to be kids.”

She looked up at him and shrugged. Her face was harder than it was when they met. There were threads of white in the darkness of her hair. When she smiled, he felt the hardness in his chest erode away.

“I may… have gotten a little carried away. I saw it was there and we could afford it.”

“And you zoomed ahead without thinking about all of what it would mean. Because you’re Solomon Epstein, and you are the smartest, most rigorous and methodical man who ever made every single important choice in his life by impulse.” If there hadn’t been warmth and laughter in her voice, it would have sounded like a condemnation. Instead it sounded like love.

“I’m cute, though,” he said.

“You’re adorable. And I want to hear all about your new whatever it is you’re going to try. Only first tell me that you’ll try to think about the future next time?”

“I will.”

They spent the evening with him talking about power and efficiency, ejection mass and velocity multipliers. And when that was done, they talked about building a responsible retirement plan and making sure their wills were up to date. It felt like an apology, and he hoped that they’d be able to do it again when she understood how much maintenance on the yacht was going to cost. It was a fight for another day.

The days, he spent working as usual with the team at the propulsion group. The nights, he sat on the monitors back at their hole and designed his own things. Caitlin started a program over the network with a group in Londres Nova discussing how companies like Kwikowski could intervene in the destabilizing spiral of threat and avoidance that Earth and Mars seemed locked in. Whenever he heard her talking to the others—about propaganda and divergent moral codes and any number of other plausible-sounding vaguenesses—she brought up lithium, molybdenum. Now tungsten too. All the other things were interesting, important, informative, and profound. But unless they could figure out the ore rights issues, they could address everything else and still not solve the problem. He was always proud of her when she said that. A liberal arts background was a hard thing to overcome, but she was doing great.

Eventually, the time came to test his idea and plans. He made the long journey to the shipyards on the new public transport system: evacuated tubes drilled through the rock and lined with electromagnetic rails like a slow, underpowered gauss gun. It was cramped and uncomfortable, but it was fast. He got to his yacht an hour before the sun set at the nearby Martian horizon. He finished the last-minute tweaks to the prototype he’d fabricated, ran the diagnostic sequences twice, and took the ship up beyond the thin atmosphere. Once he reached high orbit, he floated for a while, enjoying the novelty of null g. He brewed himself a bulb of fresh tea, strapped himself into the captain’s chair, and ran his fingertip across the old touchscreen monitor.

If he was right, the additions he’d made would increase efficiency by almost sixteen percent above baseline. When the numbers came back, he hadn’t been right. Efficiency had dropped by four and a half. He landed back at the shipyards and rode the transit tube home, muttering darkly to himself the whole way.

The United Nations issued a statement that all future Martian ships would be contracted through the Bush shipyards on Earth. The local government didn’t even comment on it; they just kept on with the scheduled builds and negotiated for new ones after that. The United Nations ordered that all shipyards on Mars shut down until an inspection team could be sent out there. Seven months to get the team together, and almost six months in transit because of the relative distances of the two planets in their orbits around the sun. Sol was a little nervous when he heard that. If they closed the shipyards, it might mean grounding his test yacht. He didn’t need to concern himself. The shipyards all stayed open. The rumors of war started up again, and Solomon tried to ignore them. Tried to tell himself that this time would be no different than the one before or the one before that.

Raj, to everyone’s surprise, resigned from development, rented a cheap hole up near the surface, and started selling hand-made ceramic art. He said he’d never been happier. Voltaire got a divorce and wanted all the old crew to come out the bars with her. There were eight of them now, but pretty much nobody went. Julio and Carl had a baby together and stopped socializing with anyone. Tori went in on a little chemical safety consultancy that pretended to serve any business with a Martian charter, but actually got all their business from the terraforming projects. Malik died from an unresponsive spinal cancer. Life struggled on, winning and failing. Solomon’s experimental drives got to where they were almost as good as the unmodified ship. Then a little bit better.

A year almost to the day after he’d bought it, Solomon rode out to the yacht with a new design. If he was right, it would increase efficiency by almost four and a half percent above baseline. He was in the engine room installing it when his hand terminal chimed. It was Caitlin. He accepted the request.

“What’s up?” he asked.

“Did we decide to take that long weekend next month?” she asked. “I know we talked about it, but I don’t think we made a decision.”

“We didn’t, but I’d better not. The team’s a little behind.”

“Overtime behind?”

“No. Just keep-showing-up behind.”

“All right. Then I may plan something with Maggie Chu.”

“You have my blessing. I’ll be home as soon as this is done.”

“All right,” she said, and dropped the connection.

He tested the housings, did an extra weld where the coil would suffer the most stress, and headed back up for the captain’s chair. The yacht rose through the thin atmosphere and into high orbit. Solomon ran the diagnostics again, making sure before he started that everything looked good. For a almost half an hour, he floated in his chair, held in place by his straps.

As he started the burn sequence, he remembered that the team was going to be in Londres Nova the weekend he’d been thinking about taking off with Caitlin. He wondered whether she’d put her plans with Maggie Chu in place, or if there was still time to change things. He started the burn.

Acceleration threw Solomon back into the captain’s chair, then pressed his chest like a weight. His right hand landed on his belly, his left fell onto the upholstery beside his ear. His ankles pressed back against the leg rests.
