What BBN said about it

Hank Ledger · Lead AnchorThe claim under review: the moon is shrinking. Ten thousand cracks on its surface show by how much, Space.com reports.

Dale Bearman · Chief Skeptic & ContributorShrinking. I knew it. The one thing in the sky I trusted to stay the same size.

Hank Ledger · Lead AnchorThe study estimates the radius has shrunk by about forty-five meters, which is one hundred forty-eight feet.

Hank Ledger · Lead AnchorResearchers found more than ten thousand young faults in orbiter images.

Dale Bearman · Chief Skeptic & ContributorA hundred and forty-eight feet. That's a whole cricket pitch and a bit, gone off the edge.

Hank Ledger · Lead AnchorOver four hundred to eight hundred million years.

Dale Bearman · Chief Skeptic & ContributorRight. So it's been at it for ages and only now do we hear.

Hank Ledger · Lead AnchorHere's the catch. The study lead says the interior keeps cooling and contracting, so existing faults should grow and new ones should form.

Hank Ledger · Lead AnchorAnd some proposed Artemis landing sites sit near active fault zones.

Dale Bearman · Chief Skeptic & ContributorSo you land on a cracked moon that's still cracking. Wonderful. I'd park somewhere else, personally.

Hank Ledger · Lead AnchorCeremonial rating: Mildly Bonkers.

Hank Ledger · Lead AnchorIt lost a hundred and forty-eight feet of radius over hundreds of millions of years, and the complaint is only now being filed.
