The strongest version of this theory

If one Moon rock was fake, why trust the rest?

A rock presented by a U.S. ambassador, during the Apollo 11 astronauts’ own goodwill tour, turned out to be petrified wood. The museum had confirmed it with a phone call to NASA. [1] For a skeptic, that is exactly what a fraud would look like.

    Associated Press report on the Rijksmuseum’s announcement.

What actually happened

A private gift with no paperwork, and the real samples.

The stone was a private gift on 9 October 1969 from Ambassador J. William Middendorf, who later said he got it from the State Department and could not recall the details. It came with no NASA certificate. The museum said it had checked only with a phone call, and NASA had told it that the gift rocks given to more than 100 countries came from later missions. [1][2]

The Netherlands also received NASA’s official Apollo 11 goodwill display: tiny fragments sealed in acrylic. In 2024 researchers examined those fragments with X-ray methods without opening them. They found a titanium-rich basalt that matches Apollo 11 samples. [3]

Nobody knows where the petrified wood came from. It may have been a mix-up or a joke, but it was never part of NASA’s sample program.

What we can’t tell you. The origin of the wood is still unexplained.
