This is amazing. The probes, which have been orbiting the moon to monitor gravity variations, will hit the unnamed mountain at 6051 kilometres per hour. It really is science fiction stuff but this Time article is the first I've heard of it.
Tangentially it also further undermines the arguments of those wacky moon landing conspiracy theorists. One of the reasons for crashing the probes is apparently to avoid any risk that they will come down on the Apollo landing sites and damage the relics left by early moon explorers.
If whatever shady government agency is supposed to have faked the moon landings were really interested in removing any damning evidence why would they not grasp this brilliant opportunity? Accidentally hitting the supposed sites of landings with crash landing space craft and obliterating them would be an eminently practical way of launching a cover up!
