Moon’s time capsule: Apollo-era rock core sample tells tale of ancient landslide.

NASA intentionally set aside a significant portion of this haul for future study, a decision now paying off.

The rock core was studied using advanced micro-CT scanning to analyze its contents in fine detail, an imaging technology that didn’t exist when the samples were first brought back.

The new research focused on clasts, fragments broken off from the mountain during the landslide.
