Chapter Text
The capsule vibrated in a way that wasn’t violent, but constant—like a living thing humming under pressure.
Christina Koch had trained for this sensation for years. Centrifuges, simulations, underwater mockups that mimicked weightlessness. Every possible scenario rehearsed, deconstructed, mastered.
None of it captured this.
Because none of it had the stakes of reality pressing in from all sides.
Outside the narrow, reinforced windows of Orion, Earth was already receding—no longer the endless horizon of home, but a curved, luminous boundary of blue and white. Fragile. Finite.
Beautiful in a way that almost hurt to look at.
Christina forced herself to shift her focus back inside the capsule.
Instrumentation. Data streams. Breathing steady.
Control.
“Guidance is holding nominal,” she said, voice even over the comms. “No deviations.”
“Copy that.”
Reid Wiseman.
His voice carried that same grounded calm it always had. Measured. Unshaken. The kind of tone that made chaos feel manageable.
Christina didn’t look at him right away.
That had become a habit she didn’t entirely trust.
Instead, she ran through her checklist again, fingers moving with practiced precision over controls she could operate blindfolded.
They were officially committed now.
No turning back.
It hadn’t started here.
It had started months ago, in a room that smelled faintly of coffee, whiteboard marker, and recycled air.
Training.
The conference room at Johnson Space Center was too cold—always too cold—and Christina had learned to ignore it the same way she ignored most discomforts: by outworking them.
A stack of mission protocols sat open in front of her, annotated, flagged, cross-referenced.
Across the table, Reid leaned back in his chair, one arm draped casually over the backrest, listening as one of the instructors walked them through contingency scenarios.
He looked relaxed.
He wasn’t.
Christina had learned that quickly.
Reid’s version of focus didn’t look like tension. It looked like ease sharpened to a point.
He caught things others missed. Not loudly. Not dramatically. Just… precisely.
“Let’s run that again,” he said, interrupting mid-brief.
The instructor paused. “Issue?”
Reid tilted his head slightly, eyes narrowing just enough to signal something was off.
“Timeline overlap,” he said. “If we hit that failure during trans-lunar injection, we’re stacking procedures that compete for the same system priority.”
Christina’s pen stilled.
He was right.
She’d seen the scenario. Reviewed it twice. And still—
She hadn’t caught that.
A flicker of something—annoyance, maybe—moved through her chest.
Not at him.
At herself.
She flipped back through the protocol, scanning fast, recalculating.
And there it was.
A narrow window. A potential conflict.
Subtle enough to miss.
“Good catch,” the instructor said.
Christina spoke up before she could second-guess it.
“We could stagger the sequence,” she said, already mapping it out. “Delay secondary diagnostics by—what—eight seconds? That should prevent the overlap without compromising response time.”
Reid looked at her then.
Directly.
Not surprised. Not impressed.
Just… engaged.
“Seven,” he said.
Christina frowned slightly. “Seven risks incomplete readouts.”
“Eight risks escalation delay if it’s a cascading failure.”
A beat.
He held her gaze—not challenging, exactly. But not backing down either.
Christina recalculated.
Again.
Fast.
He was right.
Seven seconds was tighter. Riskier in one direction, safer in another.
Balanced.
She exhaled slowly. “Seven.”
Reid nodded once.
“Seven it is.”
That was the first time she noticed it.
Not the disagreement.
The alignment.
Back in the capsule, days later—though it felt like time had stretched into something less defined—Christina finally allowed herself a glance in his direction.
Reid was already looking at her.
Not in a way that lingered too long. Not enough to be called anything.
But enough.
“Everything good?” he asked.
She nodded. “Yeah.”
A pause.
Then, quieter, “Just… recalibrating.”
A hint of a smile touched his mouth.
“Yeah,” he said. “That part never really stops.”
Outside, Earth kept shrinking.
Inside, something else—something far less predictable—was beginning to take shape.
