Alongside the transcripts of visual anomalies, a newly unsealed document details a report from Apollo 17 astronaut Jack Schmitt. During his time on the moon, Schmitt reported seeing a sudden, unexplained ‘flash on the lunar surface north of Grimaldi [crater].’

During Apollo 17, the final manned mission to the moon in 1972, astronaut Jack Schmitt experienced a highly unusual visual anomaly that was kept classified for decades.

According to a newly unsealed document, Schmitt urgently reported seeing a brilliant, sudden, and entirely unexplained ‘flash’ directly on the lunar surface.

Schmitt pinpointed the exact location of the mysterious light burst, stating that it occurred just north of the massive Grimaldi crater on the western edge of the moon's near side.

The report adds immense credibility to the study of Transient Lunar Phenomena (TLP)—short-lived shifts in light, color, or appearance on the lunar surface that have long baffled astronomers.

While some scientists argue the flash could have been a meteor impact or outgassing, internal analysts flagged the event as potentially artificial in nature.

The documents reveal that Mission Control acknowledged the sighting but swiftly instructed the crew to shift to a secure channel, effectively burying the incident.

With NASA's Artemis program preparing to return humans to the moon, Schmitt's ‘lunar flash’ report raises urgent questions about the true environment awaiting the next generation of astronauts.
