❯ A Discarded SpaceX Falcon 9 Upper Stage Hit the Moon’s Far Side on August 5

CRASHA SpaceX Falcon 9 upper stage, left stranded in space after its January 2025 launch, struck the far side of the moon near Einstein Crater at roughly 8,700 km/h at 2:35 a.m. EDT on August 5.

CRATERNASA estimates the impact crater at about 18 meters in diameter and 3.6 meters deep, though other calculations put it at 20–30 meters. Because the impact happened on the lunar far side, it was not visible from Earth. The Lunar Reconnaissance Orbiter made one imaging pass overhead on July 29 but did not fly over on impact day; the next pass comes on August 12, so before-and-after comparison imagery and the actual crater size can only be confirmed after that. Total human-made debris on the lunar surface now exceeds 209 tons.

NO SIGNATORYWhat is worth noting is not the crater itself, but that no one is accountable for it. Debris beyond low Earth orbit still has no rules on ownership or disposal, even as the launch cadence for lunar missions steps up a level. Agencies running lunar missions will sooner or later have to write a hard constraint on final upper-stage disposal. With lunar landing launch density still climbing, impact-site selection and debris registration will directly affect safety assessments for future landing zones — in time, this must shift from scientific courtesy to mandatory reporting.

▪ SIGNALThe far side of the moon has one more crater, and no document on Earth needs to sign off on it.
