If I was on Artemis I'd spend the 40 minute radio blackout rigging all the clocks, logs, instrumentts etc to show that 6 hours had passed, then refuse to comment on what I'd seen on the far side.
This is probably why I'm not allowed on the Artemis.
@_thegeoff Clarke wrote on the author's note of 2010 that the Apollo 8 crew confessed to him they considered the idea of reporting the finding of a huge black monolith on the far side of the Moon (they already had seen 2001)

@RGBes Be fun if you could get the timing right:

"Kshhh...y god, it's full of stars..."
"Artemis, Houston, radio contact reestablished."
"Receiving you loud and clear."
"What was 'full of stars'?"
"Huh? Oh, nothing...."
