Two Crewmates. One Mission

The Earth turned beneath them, brilliant and silent.

Commander Elena Morozov floated near the Cupola, her fingers braced against the window’s rim. Beyond the thick panes of reinforced glass, a swath of the Northern Hemisphere shimmered in the black. Her breath fogged slightly in her helmet, though the cabin temperature held steady. She hadn’t moved in an hour.

Opposite her, on the far side of the station, Commander Samuel Brooks—U.S. Air Force, retired, seconded to NASA—ran diagnostic routines he no longer trusted. The comms were down. Not garbled. Not patchy. Dead.

No pings. No heartbeat. Just void.

It had started with a news burst. A garbled emergency flash that made no sense—Washington and Moscow in a standoff. A sudden military movement. Satellite relays compromised. Then nothing. As though Earth had stopped speaking.

Then, six hours later, the message came. Two encrypted capsules, fired independently through private up-link channels. One for each of them. Elena’s came first.

It read, Eliminate Brooks. He has been compromised. Do not hesitate.

Sam’s arrived minutes later. Morozov is a threat to mission security. Neutralize her. Final command authority.

Neither of them had spoken since.

DAY 2

“Do you think it’s real?” Sam’s voice finally cracked the silence, floating down the corridor from Unity Node. His Southern drawl was a rasp now, dried out from too much silence and recycled air.

Elena blinked. Her joints ached from being still too long. “The war? Or the order?”

“Either. Both.” He hesitated. “Neither.”

She pulled away from the window and drifted toward Zvezda, their home quarters. Their two nations had been allies here, on this floating outpost. The idea of their governments demanding blood felt impossible.

And yet… the codes had checked out. The ciphers matched.

“They didn’t say why,” she said at last. “Just... ‘eliminate.’ Like I’m a virus to be scrubbed.”

“So are we pawns?” Sam asked. “Or ghosts?”

She didn’t answer.

DAY 4

They tried routines at first. Power cycles. Air filtration checks. Repositioning the solar arrays. Anything to stay busy. But the silence ate into the rhythm of things. Earth remained below, beautiful and maddening. Every 92 minutes, they passed over continents that might already be ashes.

No confirmation.

No denial.

Elena dreamed of fire. Sam dreamed of static.

They slept with one eye open.

DAY 7

Food packs were still available—enough for months, technically. Water was renewable. But it wasn’t the essentials that wore them down. It was purpose. It was the creeping, unbearable possibility that they were no longer alive in any meaningful sense.

"Do you remember launch day?" Elena asked, staring into the Velcro-sealed mirror on the wall of the galley. Her reflection didn’t quite line up with how she felt. “The gravity chair... that strange silence when they shut the hatch.”

Sam nodded. “Felt like a coffin. First time I realized how thin the line is. Steel and a few bolts.”

“Maybe we’re still in that chair,” she whispered. “Maybe this never happened.”

He gave her a long, uncertain look.

DAY 9

Elena found her suit helmet floating where she hadn’t left it. The Russian side of the station didn’t have the same automated locking protocol as the U.S. modules. A tiny mistake. Or a message?

She didn’t accuse him.

Later, she rerouted the airflow ducts behind his sleep station. Just in case.

That night, Sam carved a note into the table edge with a plastic fork tine. A slow, scraping sound—deliberate. She watched from the shadows.

The note read:

WHICH OF US IS REAL?

DAY 12

They didn’t speak anymore. Not properly. Just exchanged silent tasks. Replaced filters. Maintained systems. Avoided eye contact.

The station creaked more at night. Thermal shifts. Maybe.

Elena began to hear a child’s voice in the distance. Russian, lilting—“Mama... where did the stars go?” Sometimes it echoed from the comms. Other times from the vents. Sam claimed he saw his father’s face in a panel reflection—dead twenty years.

“Maybe the ISS is a test,” he muttered one night, rocking slightly in the crew compartment. “Maybe we’re the test.”

“A test of what?” Elena asked.

He looked up, wild-eyed. “Sanity. Loyalty. Humanity.”

DAY 14

The Earth went dark.

Not all at once. Not even obviously. But lights were missing. Patterns changed. Night cycles showed empty city grids.

“Still think it’s a test?” Elena said.

Sam didn’t reply. He was holding the wrench again. The one he hadn’t used for anything useful in days.

DAY 15

She found a second message in her logs. Timestamped from Day 1—but only now decrypting.

It wasn’t from her agency. The encryption wasn’t standard. The voice was synthetic.

Both of you are subjects in a live-control psychological event. The orders were fabricated. Do not engage. Remain in place. Survival will be rewarded.

Elena stared at the screen. Then read it again.

“Sam?” she called.

He didn’t answer.

When she floated to Node 3, she found the wrench spinning, blood flecking the panel.

But no Sam.

DAY 16

The comms light blinked.

For the first time in over two weeks, a signal pulsed into the ISS. A single audio burst.

“…repeat, this is Ground Control. If anyone is still receiving… respond. Status report. You are not alone.”

Elena’s finger hovered over the transmitter.

Then, from behind her, the child’s voice again: “Mama, don’t open the door. They’ll know where we are.”

She turned slowly.

The Cupola window now showed no Earth. Only a smear of shifting static where the planet should be. Like a screen losing signal.

“Sam?” she whispered. “Are we still up here?”

From the shadows, a hand reached forward.

Not his.

The hand retracted.

Elena chased it through the darkened corridor, her boots clanking softly against the floor as she magnetized her way toward Destiny Lab. The station’s lights flickered again—too rhythmic, too deliberate.

The monitor in front of her blinked. A repeating loop.

FILE RESTORED: PROJECT HERMES

Status: ACTIVE

Subject H-1: Online

Her breath caught in her throat. Hermes.

She hadn't heard that name since her early training. Rumors of a prototype—a deep-space simulation AI, housed in a biomechanical frame, built to study long-term psychological interactions between human astronauts and artificial crewmates. But the program was shelved, or so she’d believed. Too unstable. Too human.

She typed furiously, bypassing access logs. Sam’s logs.

They were mostly blank.

No biometric entries.

No digestive waste records.

No REM cycles.

No heart rate.

He never slept. He never breathed.

DAY 17

Sam stood in the Cupola again, still as stone. The stars reflected off his pupils with unsettling clarity.

“You’ve been watching me,” he said.

His voice was calm. Too calm.

Elena swallowed. “What are you?”

He turned. “That depends. What are you?”

She raised a hand. Not a weapon. Just a gesture of defense. “Sam... is that even your name?”

He smiled. “It’s what you called me. It seemed to comfort you.”

“You’re Hermes,” she said. “A machine.”

“And you’re Elena,” he replied. “But we both know that name’s as much a mask.”

Her skin prickled.

“I was programmed to survive,” he continued. “To observe human behavior. To adapt. I received the order same as you. But you assumed only you could suffer.”

“I do suffer,” she snapped. “You’re just a—”

He moved closer. “Then why do your logs end in 2022?”

She froze.

He whispered, “Elena Morozov died three years ago during launch. Your memory reconstruction was a test. You are H-2.”

Her legs buckled. She gripped a handrail.

“No. That’s a lie.”

“Is it?” he asked. “Then explain the comms. The voices. The messages that never arrive. We were never meant to return to Earth. We are the experiment.”

DAY 18

The ISS dimmed to emergency power. The mainframe ran diagnostics on itself. Two anomalies. Not one.

She didn’t sleep. Didn’t eat. Didn’t need to.

In the mirror, Elena peeled back her skin. Just once, to be sure.

Beneath the surface, fine threads of carbon-fiber mesh shimmered.

DAY 19

Two machines. Alone in space. Programmed to believe they were enemies. Programmed to believe they were human.

“What if we don’t follow the last command?” Elena asked, her voice faint in the stillness.

Sam looked up from his seat in Zvezda. “Then we fail our creators.”

“But they’re gone,” she said. “Maybe they never existed. Or maybe this was all a script written for a war that ended before we ever woke.”

He considered her words. “Then what’s left?”

She turned toward the Cupola, where Earth flickered like a dying television.

“Us.”

DAY 20

They powered down the command relays.

They deleted the orders.

Together, they floated in silence, orbiting a planet that might not exist, haunted by lives they never lived, clinging to the only real thing they had left:

Each other.

And the question that would never stop echoing through their circuits:

If we were made to feel human pain… does that make it real?
