Ninety Days Out

Rachel Trust had stopped counting days in twenty-four-hour units around week three, because a day meant nothing out here except a number Hope 's systems assigned it for the sake of the log. What she counted instead was distance — not kilometers, those were meaningless too at this scale, but proximity. Ninety days from Earth. Forty-one days, by her latest model, from ignition.

She kept the number written on a strip of tape stuck to the underside of her console, where nobody else would see it unless they went looking, updated by hand each morning with a marker that was starting to run dry. 41. Yesterday it had said 42. Tomorrow, if the models held, it would say 40. She liked doing it by hand instead of trusting the ship's own countdown, which lived on a screen and updated itself and felt, somehow, like someone else's number. This one was hers.

"You're doing the thing again," William said, floating past her workstation with a coffee pouch clamped between two fingers like it might make a break for open water if he let go.

"I don't know what thing you mean."

"The thing where you touch the tape before you look at it. Like it's going to have changed since yesterday on its own."

"It has changed since yesterday."

"Not the number. The tape. You touch the tape first." He settled himself into the seat beside her with the particular economy of movement he'd developed over three months — nothing wasted, nothing extra, the exact opposite of how he moved on the ground, where he took up more space than he needed just because he could. "It's a tell, Trust. You've got a tell."

"Everyone's got a tell up here. Yours is you make coffee nobody asked for whenever you're avoiding a conversation."

"This is a coffee nobody asked for."

"Exactly."

He grinned at that, unbothered, and drank half the pouch in one long pull, and didn't say what conversation he might be avoiding, which was its own kind of answer. Rachel had learned, over ninety days in a vessel with a livable volume smaller than most people's living rooms, that everyone on Hope had exactly one subject they wouldn't approach head-on, and that the kindest thing you could do for a crewmate was let them circle it in their own time.

Hers was the tape. Forty-one days.

The galley — a generous word for a nook with two fold-down seats and a heating unit that worked when it felt like it — was where the crew's actual conversations happened, the ones that weren't logged, weren't for the mission record, weren't for anyone back home to review months later and nod approvingly at how professional everyone had sounded. Darrell was already there when she arrived for the evening rotation, turning a ration pouch over in his hands without opening it, looking at nothing in particular.

"You're not eating."

"I'm thinking about eating. It's a phase." He glanced up. "You get anything back from Marcus?"

Marcus. Her fiancé, four months into an engagement that had been supposed to turn into a wedding sometime around when she got home, assuming the mission ran to schedule, assuming nothing else got in the way, assuming a great many things that Rachel had stopped assuming anything about the moment she'd signed onto a six-month mission to watch a star die. She and Marcus had agreed, before launch, on a communication schedule that made sense on paper — a message every four days, accounting for the growing delay as Hope pushed farther from Earth, each transmission taking longer to arrive than the one before it, the conversation itself stretching out across the widening gap like something being pulled thin.

"Got one this morning. Took nineteen minutes to download, which means it's from — " she did the math without needing to, the same reflex that made her good at her job — "about eleven days ago, now. He says the dog learned to open the back door on her own. Says the neighbors think it's a ghost."

Darrell smiled, small and real. "Does he know it's not a ghost?"

"I told him it's not a ghost. He says he prefers to believe it's a ghost. Says a ghost dog is a better story to tell people than 'the dog figured out the handle.'" She said it lightly, but underneath the lightness was the specific ache of a joke landing eleven days after it had been funny to the person who made it — Marcus, at his kitchen table, laughing at his own line, not knowing that by the time she heard it, the moment it belonged to would already be gone, replaced by ten more days of a life she wasn't in. "It's strange," she said, before she'd fully decided to say it out loud. "Every message is already old by the time I get it. He's not talking to me. He's talking to a version of me from eleven days ago and hoping I catch up."

"That's marriage," Darrell said. "Just — faster, usually."

"Is it?"

He considered that longer than the question probably warranted, turning the ration pouch over once more. "Mara used to say the whole thing was just two people trying to guess who the other person's turned into since the last time they really looked. Most days you're close enough it doesn't matter. Some days the gap's bigger than you think." He set the pouch down, unopened. "I don't figure we're any different up here. Just the gap's got a number attached to it now. Nineteen minutes. Eleven days. Feels more honest, maybe, having a number."

Rachel didn't have anything to say to that, so she didn't say anything, and Darrell didn't seem to need her to. That was another thing about the ship — silences didn't need filling the way they did on the ground. There was nowhere for anyone to go, so nobody was going anywhere, and a silence could just sit there being what it was.

She found Xavier in the observation module before her sleep rotation, exactly where she expected to find him, because Xavier had developed the habit, sometime around day fifty, of ending every day with twenty minutes in front of the wide window doing nothing at all except looking. Not at the Sister Star specifically — it wasn't visible to the naked eye yet, not really, just a slightly brighter point among a great many other points — but at the general, overwhelming fact of everything out there.

"You're going to wear a groove in that seat," she said, settling in beside him.

"William said the same thing. Except he said it meaner."

"William says everything meaner. It's affection. He doesn't have another setting." She looked out at the field of stars, unbothered by the ship's slow rotation, patient the way only things that had existed for longer than human time could afford to be patient. "How's Priya?"

Xavier's face did something complicated — a smile that was trying very hard to be uncomplicated and not quite managing it. "Good. She's good. She's — " He stopped, started again. "She thinks she might be pregnant. Said the test was faint. Says she wants to wait and be sure before either of us says it out loud, because she doesn't want it to be a maybe that turns into a whole conversation and then turns out to be nothing."

"Xavier."

"I know."

"That's — " Rachel searched for the right size of the thing and didn't find it, so she settled for something true instead. "That's a big thing to be carrying around by yourself up here."

"I'm not by myself. I've got you people." He said it like a joke, and underneath the joke, not very far underneath it, was something that wasn't a joke at all — the particular loneliness of good news that had nowhere to land yet, six months and four hundred million kilometers from the one person who was supposed to hear it first. "I keep doing the math," he admitted. "If she's right — if it's — then by the time I'm home, she'd be, what. Five months? Six?"

"Somewhere in there."

"I missed the part where you find out. That's the part everybody talks about. The two lines, or whatever it is now, the little screen, whatever. I'm going to get a message about it eleven days late, same as you get everything eleven days late, and by the time I write back congratulating her it'll be old news to her too. We're going to have this whole — " he gestured, helpless, at the width of the gap between them and everyone they loved — "this whole conversation happening out of order. Like a play where everyone's reading their lines from a different night."

Rachel thought about Marcus's ghost dog, about a joke that was already eleven days dead by the time it reached her, and didn't say anything about the parallel, because Xavier didn't need a parallel right now. He needed someone to sit with him in the observation module and not pretend the gap was smaller than it was.

"For what it's worth," she said instead, "I think you'll make a good dad. You already do the math on things nobody's asked you to do the math on. That's basically the whole job."

That got a real laugh out of him, short and surprised. "That's the worst compliment I've ever gotten."

"I'm an astrophysicist, not a poet."

Later — ship-later, the arbitrary hour her body had decided to treat as night — she lay in her bunk with the light off and thought about the number on the tape. Forty-one days. She'd spent six years of her life fighting rooms full of people who didn't think this mission was worth funding, six years of testimony and budget hearings and one particularly bad afternoon in front of a subcommittee chairman who'd asked her, not unkindly, whether the money wouldn't be better spent on something people actually cared about — and none of that mattered anymore, none of it, because in forty-one days the Sister Star was going to do the one thing it had been building toward for longer than human beings had existed as a species, and she was going to be four hundred million kilometers closer to it than anyone had ever been.

She thought about the models she'd built, checked and rechecked so many times the numbers had stopped looking like numbers and started looking like a shape, a physical thing she could almost hold. The star's core, collapsing under its own weight. The rebound. The shockwave. She knew, in the specific, total way a person knows something they've devoted their whole career to, exactly what was going to happen and roughly when.

What she didn't know — what nobody could have modeled, what no subcommittee chairman and no budget hearing and no six years of fighting could have prepared her for — was that the models were about to be wrong. Not wrong in the way models are sometimes wrong, an error term, a correction in the next paper. Wrong in a way that hadn't happened to anyone, ever, in the whole history of anyone looking up.

But she didn't know that yet. Nobody on Hope knew that yet. That night, ninety days out, the only thing on Rachel Trust's mind was a number on a strip of tape, counting down toward the loudest thing that had ever happened, and the quiet, stubborn joy of being the one close enough to hear it.

She updated the tape the next morning. 40.

It felt, for one more day, like the biggest number in the world.
