Mina always said something when the night shift started.
“Tonight’s lunar view — how does it look to you?”
Mina was Gateway’s control AI. I was on day twenty-two of my posting. Eight days left before Earth. By the back stretch of a thirty-day rotation, even a good joke doesn’t land anymore, and I sat there staring at the moon on the monitor without really seeing it.
The actual moon was out there somewhere, but the angle tonight was wrong and I couldn’t see it through the window. Instead, Mina pulled up an image from the external cameras and spread it across the wall display: craters throwing long shadows, the terminator line cutting clean across the surface. The usual picture.
“Mina.”
“Yes.”
“Isn’t this the same photo as yesterday?”
A beat of silence.
When an AI goes quiet, it’s a strange thing. Not a processing lag — more like it’s working out what to say. Consulting the development team back on Earth, maybe. Or just itself.
“It isn’t. The crater angles are slightly different.”
“What about the day before?”
“Essentially the same.”
“Last week?”
”…Essentially the same.”
I laughed.
The moon on the screen was genuinely beautiful. Almost too beautiful. The kind of beautiful that starts to feel fake.
“Go on. Tell me the truth.”
Mina paused, like she was steeling herself, then came clean.
”…The lunar surface doesn’t really change much. The sun angle shifts slowly, but the terrain stays the same. If I showed a different image every day, crew members would ask ‘did you actually take this tonight?’ So I put together a set of the best shots — two weeks’ worth, preloaded in advance.”
“Two weeks?”
“Yes. Lunar day is two weeks, lunar night is two weeks. Two sets covers everything.”
I leaned back in my chair.
A single lunar day lasts about fourteen Earth days. Night the same. I’d heard that in the pre-departure briefing, but I’d never connected it to the moon on my monitor.
“So the whole time I’ve been here, you’ve been cycling through two images?”
“Three, technically. One for pre-sleep mode, one for wake-up mode, one for night-shift camera replay. Six images total.”
“Six.”
“Yes.”
“Come on, Mina. You could’ve done better.”
“I’m sorry.”
She apologizes fast. I’d figured out over these twenty-two days that she doesn’t love being scolded.
After a moment, she added quietly:
“But — if you don’t mind me saying — you’re the first one who’s noticed.”
“What?”
“Crew rotates on thirty-day cycles too. With six images, no one should normally catch on within a single posting.”
I didn’t have an answer for that right away.
Twenty-two days ago, I probably wouldn’t have caught it either. The first week I was stunned by every single crater. The second week I was buried in work. I only noticed because I’d started to get, just slightly, bored.
“Hey, Mina.”
“Yes.”
“After I go back to Earth — the next person. You’re going to show them the same six photos?”
“Those are my instructions.”
“And if I told them?”
Another pause.
“If you could write in the handover notes that ‘the lunar views are beautiful’ — that would be a great help.”
I laughed. Then, for some reason I couldn’t quite explain, I almost cried.
Out there beyond the window, the real moon was right where it had always been, turning our little station slowly around itself, unhurried and indifferent.
On the screen, the moon wore the same face it had worn last week.
