This is the best summary I could come up with:
After landing on the moon on December 11, 1972, NASA astronauts Eugene Cernan and Harrison Schmitt collected rocks and dust from the lunar surface.
During that time more than 4 billion years ago, a Mars-size object crashed into Earth, flinging off a large rocky piece that became the moon, according to the researchers.
So any crystals on the Moon’s surface must have formed after this lunar magma ocean cooled,” said Heck, who is also the senior director of the museum’s Negaunee Integrative Research Center and a professor in the department of geophysical sciences at the University of Chicago.
This research marks the first use of the analytical method of dating the crystals with atom probe tomography and was carried out using instruments at Northwestern University in Evanston, Illinois, according to the study authors.
Although the lunar samples were returned to Earth more than 50 years ago, it has taken time to develop the technology needed to conduct such a detailed analysis of the crystals.
This is why NASA has waited to unseal some of the pristine samples collected during the Apollo era until recent years, allowing for more insights into our planet’s natural satellite using the most advanced methods.
